The LCS1240 is a compact, cordless electric chainsaw with a brushed motor at its heart which provides excellent power output, provided that you don’t expect to bring down 15-inchers with it. At first look, this may seem to be an oxymoron, but it really isn't. In an older motor fully assembled the switch's contacts may have become pitted and burned, or its parts may be worn so that there is not enough pressure to close the contacts when the motor is not running or is first starting up. It is not uncommon for an electrolytic capacitor to dry out and fail in audio equipment after 20 years or less. Good news: With an electric chainsaw, the problems related to starting are limited.Check for one of these common issues: ­ 1. The meter is set to the 15 Amp. Use an Ohmmeter. With instant starting and no gas or oil to mix, an electric chainsaw is already quite a straightforward tool. An electronic switch does not respond to the speed of the motor shaft like a centrifugal switch does, but has a timed disconnect. When working with the electric chainsaw, do not press on the tire, the saw must smoothly enter the tree trunk. Small … or what? It will deal with 8-10-inch-thick logs easily and it works like a charm. I believe I was pretty much able to work the end castings farther and farther out toward the end of the shaft. Be patient. It is not a recommended procedure, but I figure it is suitable for a motor I use only occasionally in my workshop. The best answer I can give is to follow the instructions supplied with the motor. Reason things out. wikiHow is where trusted research and expert knowledge come together. 2 years ago. I realized I made an assumption the centrifugal switch is working. You have checked for shorts. At the worst, you will be out a relatively small amount of money, and it may be your capacitor has a flaw that does not show itself in the tests you are able to conduct. Capacitors can give good readings on a meter and still be weak or failed. I couldn't see the back of the endcaps very well, I didn't realize the bearings would pull through it. But, replacing a start capacitor without first checking for shorted or open windings, an open reset, and a faulty centrifugal switch will not make your motor run, if the capacitor is not really your problem. When a motor fails, it is often difficult to see why it failed just by looking at it. My electric chainsaw motor still runs, but sparks and heat are coming from the brushes and commutator. Connect an Ohmmeter to the contact points wires. 6 months ago. Thanks to all authors for creating a page that has been read 1,147,143 times. (One may go to the capacitor and one may be on a post in the junction box.) wikiHow is a “wiki,” similar to Wikipedia, which means that many of our articles are co-written by multiple authors. Here are some ways to test your capacitor. We hope our sharing is useful for you. Phil, stunning. If there is no junction box on the motor, remove the end of the motor where the power cord connects to the windings. Thanks again for taking the time. Thank you. Follow the wires as best you can. craftsman elec chain saw model 358.34118 Problem: motor does not turn on when switch is closed ( I checked switch with multimeter - it closes properly (0 ohms when pressed). I had seen a couple of wear spots on the contact plate where the spool rubs on it. […] I was using it and it was working fine. for example a 500 watts electromotor 2800 rpm. Do not jerk the tool to release the chain. on Step 4. I have a Poulan 3.5 HP electric chainsaw. It has the two shafts and similar type bearing design. At the best, the motor may run. Many digital meters do not offer the ability to zero, so skip the "zeroing" information above if yours is a digital meter. Note: This Instructable is written to share some helpful things I learned, as well as some tools and resources you will find helpful. Turn the rotors and push and pull the shaft to test the bearings; if the rotors move smoothly and there is little to no movement in the shaft, the bearings are probably fine. If your electric chainsaw stops working, here are some things to look for and what you can do to fix them. Just want i needed, have an old bench grinder that i thought i had fixed, but alias it was not to be. If one of the windings shows an open circuit, look closely at where the wires attach to a terminal or to a heavier wire. It is also possible to buy an electronic switch to replace the centrifugal switch. It is really not possible to make a photo of the centrifugal switch in all of its parts as it is in place inside the motor, so I made a side view drawing that shows the relationship of the parts. (Here is a similar device you can make.) I am assuming you have a single phase 1/4 or 1/2 horsepower motor, even possibly up to 1 horsepower. How did you get the bearings out and the end caps off?I have the end caps loose from the main housing but the bearings are not letting them go farther than that. I want to run it to a wall outlet. There was no smell of a hot motor or no unusual sounds prior to it not working. I do not want that washer to float into the contacts and inadvertently press them closed while the motor is running. It allows the starting windings to be engaged for 7.4 seconds and then breaks the circuit. But, it may also look perfectly normal. The actual reading is just a little below 7 Amps. Estimated time of constant work is 15-20 minutes. How can I check for the cause? When the chainsaw is cold (has not been run recently), the chain should sit on the bar fairly snugly, and raise around ¼- ½ an inch off of the bar if pulled. If it is connected - disconnect it before attempting the steps below. No, it’s not a sign of being in love, it’s probably just damaged or worn out motor brushes. Then it was pushed close to the iron frame of the motor where it shorted and showed a leak pathway. After that, get out your ohm meter and start checking the windings for an open coil. The wire got a scrape that left it bare in one spot. It has been designed is a way to get a comfortable grip and is self-sharpening which makes this saw as the best electric chain saw of 202o. Is there an internal fuse that is not in the explosion diagram and is hidden? This advancing magnetic field gives the rotor something to chase, causing the rotor to spin. This causes the rate at which heat can be conducted to reduce at an alarming rate. I sometimes gently pry a bearing seal off of one side, work some bearing grease into them, undo any damage to the bearing seal, and tap it back into place. To create this article, 23 people, some anonymous, worked to edit and improve it over time. Turn the motor shaft by hand. The best electric chainsaw for you may not … I have not seen any listed anywhere. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. You would need either a phase converter, basically another electric motor and control box where you would pull the other two phases of electricity from or a VFD (solid state option), either way you would run into trouble with the timer and selector mechanism in the washer. When a motor fails, it is often difficult to see why it failed just by looking at it. can it be running for hours without getting damage or be overheated? Regardless of what you do, make sure that whatever you try is done safely. I checked for shorts and opens, but the coils are fine. Many have fittings for lubrication while others are permanently lubricated or "maintenance free". Placing the test probes on the capacitor terminals, the resistance should start low, and gradually increase as the small voltage supplied by the meter's battery gradually charges the capacitor. If any of the readings indicate a pathway for electricity, double check to be certain you were getting an accurate reading. I looked closely and saw a break where the coil wire attached to one of the terminal pins. My left thumb taught me to always double check before resorting to a bigger hammer. I removed the screws visible on the end plates of my motor. At no time during the motor check out is power required. A chainsaw that offers tool-free guide bar chain replacement and adjustment option is most preferred. After 61 years the rubber covered cord has several cracks. The purpose is to give the reader enough help to make some careful tests and solve some basic problems. So it is essential to know your saw, how it fits together, and how it uses power. An example could be an "open" circuit caused by an electrical failure caused by a foreign object that falls into or is drawn magnetically into the motor or excessive voltage that literally causes a wire in the winding to "blow up" or melt. I did whallop the one cap too hard and broke the overload switch. Thank you for reading. When I assembled the motor and put power to it, the shaft turned about 1/8 of a turn, froze, and growled. Chainsaws can be very hazardous if they are used improperly, and severe injury can result. 2 years ago. Procedure A--With at least one wire removed from the capacitor and no power to the motor circuit, attach an Ohmmeter to both terminals of the capacitor. If you have any of those things, look for frayed wires in the power cord touching another frayed wire or shorting to the iron frame of the motor. Make sure your hands are not touching the metal probe tips, as doing so will cause the reading to be inaccurate. But, some capacitors in older motors may also be flat, like a short stack of 4 x 6 index cards. Please help us continue to provide you with our trusted how-to guides and videos for free by whitelisting wikiHow on your ad blocker. As it's an electric chainsaw, a broken switch can cause serious harm. It worked when I bought it at a used tool sale about two years ago, but the ball bearings sounded rough when the shaft was turned by hand. A few months later it did not run. It should provide voltage tables matching the correct color codes and / or jumper settings for voltage selection. The reading should rise to a high number and drop suddenly to zero or an open circuit. Hopefully, there are no sparks or shocks from the motor frame, and the circuit breaker does not immediately trip. MCBs should be of type C or D to allow for inrush current, and the Z ratings of the circuit must be below the specified threshold in your locality for the rating of the overcurrent device. If the problem seems to be electrical, use an ohmmeter to check resistance value. Once I snagged a thin enamelled wire from one of the windings when I was inserting the rotor. You mentioned you pulled the motor apart to service the bearings. In these chainsaw reviews we take a look at some of the top, best-rated electric chainsaws that are currently available to buy in the UK. The WEN 4017 16-Inch Electric Chainsaw is meant solely for light to medium yard work and for that, the 12 Amp electric motor meets expectations. You may find that when it runs ungrounded that the casing becomes live at up to supply voltage. The best chainsaw machines 2020 require maintenance which get the chainsaw working like it should. What is the best reliable device to use for protecting the motor against over-current? While a chain saw does produce some heat while in use, it should never overheat or begin smoking. I was a Lutheran pastor for forty years and still fill in regularly. This article has been viewed 1,147,143 times. 3 Phase motors are usually additonally protected by a thermal overload relay or electronic equivalent which is much more accurate and the same device can be used for single phase if desired. You can find that by checking the ohms between the motor terminals, if shorted or not . These may be located in the base of the motor so that outward appearances make it seem the motor has no capacitor. It passed every one of them. Now you have known how to start an electric chainsaw. (Make some photos showing the connections so you can make them correctly again, if you need to take them apart.) The ends of the motor have rather large openings and the windings in the stator windings are plainly visible. I am enjoying posting things I have learned and done since I got my first to…, How to Make a Bent Plywood Modern Mantel Clock, No-waste Plywood Trunk With Lid Storage and Walnut Trim, 16-3 power cord and plug (if needed to replace an old cord), Sharply pointed round prying tool (for lifting bearing seals), Hammer, punch, and flat surface (for smoothing bearing seals before reinstalling), Capacitance meter (optional, but nice to have--See step 5. Where something lacked enough detail for me I went on-line and looked for additional material or for videos at YouTube. When finished, restore the connections to the capacitor, either the old one or a new one. Step 1 – Engine Does Not Start. The old cord was two wire. It is also probable that the starting windings are not working properly, but there could be more than one reason for that. ). Unlike a typical chainsaw manual , this one discusses the issues which can emerge in course of time. A chainsaw is a very useful tool for house owners and professionals alike, till it stops working! These types of motors are what you will find in most home and workshop applications. But, the field coil showed an open circuit between the two terminal pins. If you are not able to find the break in the coil circuit and repair it, the motor will need to be rewound. Motor capacitors are usually a cylinder with terminals on top. Do this a couple of times, just to be safe. will bring it out again, dust it off (very dusty) and with your pdf in hand, have another crack at ti :). All motors should be protected by an overcurrent device (MCB) in the consumer unit, and a residual current device (RCD or GFCI). What should I test if my fan only works on low speed whether the switch is low or high, and the capacitor tests are fine? However, if you are actually asking, "How do I connect the wires in a motor? There is no sound but the trigger reacts as if the machine is not plugged. A mathematical formula tells how many microfarads your capacitor yields, given the parameters of the test. See the first graphic. With it being plugged in the trigger will not work to power the change saw. s1? I sat it down and when I picked it up to cut my next item, it would not run. I opened the motor and packed the bearings with new grease. Look for that first. There are ways, albeit not very efficietnt, to run a three phase motor on single phase 220 volt current, but, if your wall outlet is 115 volts, it is an unworkable situation. My motor purrs like a contented kitten. If your machine is able to spin at a fast enough rate but you are still not able to get the efficient cut that you are after there are a … Look closely at your motor and find the wires that lead to the stationary switch contacts. Whether it is through a chargeable battery or directly from an outlet with a cord, … I always enjoyed boiling things in the Bible down to simple steps in simple terms so people grasped something they did not previously know or understand. what type of duty cycle are washing machine motors? I made a different washer from 16 gauge steel sheet to fit on the end of the spool. Could you describe how you did that? If they are, then the problem could be dirt buildup in the commutator. Connect one lead to the iron frame of the motor. It acts as if no power is getting to the motor. The tests above give you an idea about whether a capacitor is working, but give you no hint about the actual capacitance of the capacitor. Procedure D--It is not always feasible to buy several pieces of test equipment you may not use more than once or twice. Procedure C'--The book mentioned in the next step provides another test. Can really only be electrical connections, motor or drive to chain, no ? I was able to coat the wire with an insulating liquid and push it out of the way. Is the extension cord plugged in? There was no indication of an open circuit in any of the armature coils. Unplug the motor from its power source. Otherwise, repairs can not be avoided. For the case of the electric chainsaw, the parts to be checked are not as much as in the case of the gas options. I now have a digital multimeter with capacitance reading. I believe a washing machine motor has a capacitor like the one in this Instructable, although it may be mounted away from the motor. I bought three wire and will connect the ground wire to the motor frame to bring it up to present day standards.. The magnet above the table chases the magnet under the table in a crude form of an electric motor. checks out in your motor and the capacitor gives indications it should be good, but the motor still does not run, a new capacitor is $10 to $20 shipped to your door. 10 months ago. At least one uses an Arduino module. I bought the book because some people I know somehow think I know enough to help them with their electric motor problems. When I connected an Ohmmeter to the wires that go to both sides of the stationary part of the centrifugal switch, the contact points did not provide an electrical pathway, even though I had cleaned and polished them with fine sandpaper. Coil windings inside the motor quickly heat up on a motor that does not run and the coils can be destroyed. A capacitor can pass several tests and still fail under a load. You might have to strike the end of the shaft with a soft dead blow hammer. If you have a saw that runs on fuel, the troubleshooting process will be different from an electric model. Access the connections between the power cord and the motor windings. If there is a steady reading of some value, the capacitor is shorted. The centrifugal switch must have been on the edge. Hi Phil,Thank you for the reply. An ESR meter measures internal resistance that effects actual performance. I am not an expert, but this is what I remember reading. This corded chainsaw does not require gas for its working. The bulb should light, although may be dimmer than usual. Coil windings inside the motor quickly heat up on a motor that does not run and the coils can be destroyed. In a nutshell? (Whoops) Check the power cord to ensure it’s connected to both the saw and the outlet. If you have anything new to share, do not hesitate! Not all electric chainsaws use a rechargeable battery as some have a power cord that needs to be plugged into the mains. Then the centrifugal switch locks out the components of the starting winding circuit. That could cause the starting winding to burn out. and improve them greatly. The motor shaft spun freely and smoothly when turned by hand with no power. It has been very helpful. It really shouldn't matter, an AC single-phase motor can be connected either way. Remove the junction box cover plate, if there is one. How do I check and find out with a multi-meter whether a motor is faulty or not? This results in a broken path - or "open circuit". If the motor of an electric chainsaw starts to smoke, it’s a sure sign that you have pushed it a bit too far. We use cookies to make wikiHow great. Remember that you are working with a tool that is not only electrical, but is also designed to cut, and it will do that to whatever gets in its way, including you. I tested my switch contacts with the motor fully assembled. That could overheat and destroy the starting windings. Best Electric Chainsaw Reviews. 4. The book is now drenched in ink from my underlinings and marginal notes. Connect the other lead to each of the wires coming out of the motor, including those that connect to the capacitor. All tip submissions are carefully reviewed before being published. I finally did that, using a common washer for each mounting screw, and I removed the washer I had made. Pat. For information on how to check the fan and the bell housing, read on! But, the washer could move to put pressure on the centrifugal switch contacts and engage the starting winding while the motor is running. It doesn't happen often - but it does happen. Overheating also occurs when an electric motor is forced to operate in a high temperature environment. An electric chainsaw, as the name implies, relies on electricity instead of gas to power its motor and allow the chain to rotate. Where to start ? It is not that uncommon for a motor's windings to be both "open" and "shorted" at the same time. See the text boxes.The centrifugal switch normally presents a closed circuit, if it is working properly. I checked my book and another option is to add a spacer between the motor frame and the stationary part of the centrifugal switch. If the chain is too tight, the blade may not spin when the throttle is engaged, which can cause damage to the clutch or other associated parts. If the chainsaw stops working while the motor is smoking and it won’t start up again, then the motor is most likely fried for good. Here are a few things to try when your electric chainsaw does not work properly. Thrust washers may be used to move it a little, if there is space for the washers.) Perhaps someone can correct me. It is about 208 volts. I smoothed out the seals as best I could and put them back. If the bearings are not rusted inside, you can probably work new grease into them. I certainly did not damage the pulley. Electric Chainsaw Buying Guide. If it's a 3-phase motor, you have to swap only two phases. TEFC motors on the other hand, can be used in all the previously mentioned areas but must not be submerged unless designed specifically for the purpose. Thanks for the effort.Jerry, Reply About 25 years ago I had an electronics magazine with a home built circuit for a capacitance meter based on a 555 IC. Procedure B--Remove both wires from the capacitor. You also should have a look at the oil bar and also check if it's lubricating the bar smoothly. It was not a perfect solder joint, but the Dremel worked again.) I now realize some logical basic testing and thoughtful deduction will help me to solve the basic motor problems I can expect to see. The reviews above are meant to give you a better picture of what a great electric chainsaw is all about. How do I reverse the direction the motor runs? If you still find evidence of a pathway for electricity, one of the windings is shorted to the motor frame. These can be used "in circuit" and give an accurate reading without feedback through other parts of the circuit. This article has been viewed 1,147,143 times. Procedure C--You can get a meter that reads the capacitance value of a capacitor here for less than $20 plus shipping. Could you post a photo of your motor from the end? Such junctions are the most common places for an open junction to happen. Get out your ohmmeter, open up the fan, and check the continuity of all of the coils in the fan motor. I was still absolutely certain the capacitor is faulty. (If you see ratings in millifarads, 1 millifarad equals 1000 microfarad.). An electric chainsaw will stop working for different reasons than one that uses fuel like petrol and a motor with air filters and spark plugs. Share it with us! The dead blow hammer did the trick. Have this exact motor for my drill press. The centrifugal switch on that motor also had a problem. A capacitor may bulge or leak when it is failing. 7 months ago. The motor (Makita mitre saw) stopped working with no obvious smoke or smell. Many motors have a domed cover on the outside of the motor, and the capacitor is under it. This could indicate the motor needs to be rewound. To determine the problem, you can look for certain “symptoms” that will tell you what needs to be fixed. I was runing a 240v 2kw motor off a faulty generator which I now know was producing less than 240v. I think I used a puller and it yielded quickly without much stress to the pulley. Most motors use a centrifugal switch to disconnect the starting winding from the circuit as soon as the motor shaft builds most of its speed. Include your email address to get a message when this question is answered. There are various test procedures for capacitors, but those tests are not foolproof. Also, bridge the two terminals of the capacitor with a screwdriver to remove any charge that could shock you. Not sure just what you are talking about. Chainsaw engines are traditionally either a two-stroke gasoline (petrol) internal combustion engine (usually with a cylinder volume of 30 to 120 cm 3) or an electric motor driven by a battery or electric power cord. After prolonged use of your chainsaw, you will notice your motor will start to run slow or lose power. Don't forget to check the switches and throttle if they're working instantly and adequately. The reviews have not been conclusive about which one of the electric chainsaws is the best. Then the motor needs to be rewound to work again. Then make some careful tests in a logical order. Hello, I just got a Powr Kraft Montgomery Ward 1/2hp 1725 rpm motor similar to the Craftsman motor in your article here. I did several tests of the capacitor. Special purpose industrial motors (DC, three phase) will have some differences and I still know nothing about them. Combustion engines today are supplied through a traditional carburetor or an electronically adjustable carburetor. Tip References. Electrically checking a capacitor can be done with the ohm meter. Another option is to put a spacer under the stationary part of the centrifugal switch to bring it nearer to the spool.). Then the motor needs to be rewound to work again. It depends on the voltage supply, such as 110v or 220v. While there are reasons a chainsaw/pole saw won’t cut, you might end up losing your hard work.
