Have makita demo saw with auto decompression but will not decompress when trying to start
If your Makita demo saw has an auto decompression feature but is not decompressing when attempting to start, there could be a few potential causes for this issue. Here are a few things you can check:
- Check that the decompression valve is functioning properly. It could be clogged or stuck and not allow the engine to decompress.
- Check the air filter. A dirty air filter can restrict airflow to the engine, making it difficult for the saw to start. Clean or replace the air filter as needed.
- Check the spark plug. A fouled or worn spark plug can also make it difficult for the saw to start. Clean or replace the spark plug as needed.
- Check the fuel filter. A clogged fuel filter can restrict fuel flow to the engine, making it difficult for the saw to start. Clean or replace the fuel filter as needed.
- Check the carburetor. A dirty or clogged carburetor can restrict airflow and fuel flow to the engine, making it difficult for the saw to start. Clean or rebuild the carburetor as needed.
- Check the fuel level. If the saw runs out of fuel, it will not start. Make sure the fuel tank is filled with fresh fuel.
It's worth mentioning that if the saw is still under warranty, it is best to contact Makita's customer service and ask for assistance.
If you are not comfortable working with the engine, it is best to consult a professional or refer to the service manual for your specific saw.
My dc18ra makita battery charger flashes red and green lights no matter how many bateries i try
The pcb inside the battery has a microcontroller that monitor the
charges and charge cycle. When the cell falls below a certain voltage,
it will instruct the charger not to charge and will show with a
red-green flashing light. If the battery has been tried 3 times in
succession then the pcb will brick itself from the makita charger. So
first replace the bad cells. There are 2 solutions at this moment:
charge with a 3rd party lithium charger like the imax b6 or replace the
pcb with a working one. check out my blog on
