There are a variety of chainsaw, those that run on electricity, compressed air and even hydraulic power though most of chainsaw in the current market are powered by two-stroke petrol engine. One can save a great deal of time and money when his or her electric chainsaw goes out. One can look at the performance of the chainsaw to determine what need to be fixed or replaced.
1. When the engine does no start
This is a common failure to the electric chainsaws. First check to see all the connection to the switch are proper since there could be a problem with the switch. Also you will need to check if the power code is intact and plugged in correctly. If this checks are all good then you can replace the switch.
2. The chain saw produces smoke
Production of smoke is an indication that there is little or no lubrication in the machine. This damages the chain and the chain bar. Check the oil reservoir before operating the machine. To check if the oil pump is functioning correctly, hold the tip of the saw over a light-colored area, hit the throttle to check if oil sprinkles across the chain bar. If it does not, turn the machine of remove the chain guard bar and check if the oil discharge slots are mixed with saw dust. Clean out the saw dust and restart the machine.
3. Chain jumps during operation
This failure is caused by the engine drive sprocket when it gets worn out. When the sprocket gets worn out, the chain does not settle properly in it. If the sprocket is in right condition then check the chain’s tension. Also a dull and overworked chain will skip during operation.
4. Improper cuts
You will know that your chains has improper cuts when it cuts at wrong angle or shoots out a lot of sawdust. Get the chain sharpened. Also a dull chain can cause kickbacks than can cause chain break. The chain releases tiny particles that are harmful to the machine. You need to check for any tiny shinny particle and examine each cutter for damage.
5. Chain continues to move or suddenly stops
When the engine idles and the chain continues to move, check and make sure the idle is set at right place that is not too high or too low. Make sure too the brake is not engaged.
6. Loses power
This happens when there is a break in connection while operating. Make sure all connections are intact.
N/B if the problem seems more technical, you can always consult a professional.
