An electric chainsaws, as the name implies, relies on electricity instead of gas to power its motor and allow the chain to rotate. Chainsaws are quite useful for trimming tree branches, lumberjacking and many home construction projects that involve wood. Chainsaws can be very hazardous if they are used improperly, and severe injury can result. As a result, an electric chainsaw needs to be examined thoroughly in the event of any mechanical malfunction before it is used again. Troubleshooting an electric chainsaw requires some diligence.
If the chainsaw is not working properly, charge the battery. If it has a battery, but the chainsaw still does not operate properly, the battery may be faulty and needs to be replaced. If it does not start even with the chainsaw plugged into the battery, the battery is not likely the culprit.
If the chainsaw still won't start and the battery looks healthy, replace the chainsaw's motor.
If the chain is dull and not cutting properly, replace the chain. Soak the new chain in SAE lubricant for at least 6 hours before installing it on the saw. Tensioning is recommended according to the saw's instructions, but the chain will most likely be stretched in the first 30 minutes of operation. Double check the tension after light use to ensure the new chain is properly adjusted.
Check the guide plate when replacing the chain. A damaged guide plate will wear out the chain quickly. Before putting a new chain on the saw, replace the guide plate if it looks warped or worn.
Make sure the chain and chainsaw components are properly lubricated. A dry chainsaw may not operate properly and may be louder than an oiled saw. A dry saw may also begin to smoke, a sure sign that it needs to be oiled. The incorrect type of oil can also damage the saw components.
If your chainsaw has a chain oiler, fill it up. It automatically keeps the chain lubricated during operation, but it needs to be checked frequently to make sure there is proper oil in it.
