Fixing a Broken Chainsaw

A chainsaw is often needed in emergency situations, so having your chainsaw ready and available at all times is important. Whether your chainsaw is for cleaning up downed trees, pruning, cutting firewood, or carpentry projects, proper maintenance is critical. It can also be expensive to get a broken chainsaw repaired. You can save time and money by repairing it yourself. For chainsaw repair you will need a work bench to set the chainsaw, a chainsaw tightening tool, files to sharpen the blades, and any necessary replacement parts.

My Chainsaw’s Engine Does Not Start or Runs Rough

If the engine will not start at all, check the spark plug and make sure you have a strong spark. If not, then replace the plug. If there is a strong spark, then it is most likely a fuel problem. The main cause of this problem is stale fuel which is caused by fuel breakdown during long term storage. If a fuel stabilizer is used when the piece of equipment is stored for the winter or more than sixty days, this problem could be avoided. The best option is to add fuel stabilizer to your fuel mixture every time fuel is purchased. What typically happens is that the diaphragm inside the carburetor has been hardened by the fuel that is sitting in the carb while it is being stored, the diaphragm is not pliable anymore. If after adjusting the rpm needle valves and it still does not run properly, it is definitely a carburetor issue. The simplest and cheapest solution is to install a carb kit. The kit costs about $20 depending on brand and takes about half hour to install. While you have the carburetor apart, you should clean it with a cleaning solvent. A more expensive, but easier and quicker option is to purchase and install a new carburetor from your local parts dealer.

My Chainsaw Smokes

If there is smoke coming from the chain, it could be an indication that there is not enough lubrication. Without the proper lubrication, the chain and chain bar can become seriously damaged. Make sure there is oil in the reservoir. When you start the saw, the automatic oil pump should lubricate the chain and bar. To see if this is a problem, hold the saw tip over a light-colored surface, hit the throttle and look for oil spatters on the chain bar. If you see no oil splatters, turn the saw off. Remove the chain guide bar and see if the oil discharge slots are clogged with sawdust. Clean out the sawdust and restart the chainsaw to check lubrication again.

The Chain Skips or Jumps

If the chain skips or jumps during operation, check the engine drive sprocket to make sure it is not worn. If you have a worn sprocket it will not allow the chain to sit properly. Also, check to make sure the chain tension is set correctly. Setting the chain tension is a part of continuous operation. However, a dull or damaged chain may also cause the skipping and jumping.

My Chainsaw Isn’t Cutting Properly

If the saw cuts at the wrong angle or shoots out a lot of sawdust, you probably need to sharpen the chain. A dull chain can be very dangerous. It can cause a kickback or chain jump that might break the chain and release pieces that could harm to the operator. If your chain looks relatively new, you need to examine each cutter for damage. Use a file to sharpen the cutters.

The Chain Continues to Move or Stops

If the chain continues to move while the engine idles then you should check to make sure the idle is not set too high. If it stops while cutting, see if the brake is engaged.

My Chainsaw Loses Power

If the chainsaw loses power while operating, check to make sure all electrical connections are secure. Any break in current may cause the saw to decrease in power, stall or shut down altogether.

As a final reminder, consult your user’s manual for questions specific to certain manufacturer types.
