Makita BUC122 Problems and Solutions
some common issues and solutions for the Makita BUC122 electric chainsaw, as recommended by experts:
- The chain is not cutting properly.
- Cause: The chain may not have the proper amount of tension. If the adjustment screw is too loose, the chain may not make good contact with the wood. If the chain is too tight, the chain may not rotate at the proper speed, causing the chain not to cut properly.
- Solution: To adjust the chain, tighten or loosen the adjustment screw. The screw is located on the side of the chainsaw, near the chain sprocket. Turn the screw clockwise to tighten the chain, and counterclockwise to loosen it.
- The chain is getting stuck in the wood.
- Cause: The chain may be dull or damaged. A dull or damaged chain will not cut through the wood as easily, and may get stuck.
- Solution: To sharpen the chain, you will need a chainsaw file. Follow the instructions in your chainsaw's owner's manual to sharpen the chain properly. If the chain is damaged, you will need to replace it.
- The chainsaw is not starting.
- Cause: The chainsaw may not have enough oil in the tank. A chainsaw needs oil to lubricate the chain and bar, and if the oil level is too low, the chainsaw may not start.
- Solution: Check the oil level in the tank and add oil if necessary. The oil level should be between the "MIN" and "MAX" marks on the tank.
- Other possible causes: The spark plug may be dirty or damaged, or the fuel filter may be clogged. If the chainsaw still does not start after checking the oil level, you may need to clean or replace the spark plug or fuel filter.
