    Why is the main power lamp blinking on my Makita DUC303 Chainsaw?
    • B
      Bradley BrennanSep 10, 2025
      The main power lamp on your Makita Chainsaw might be blinking because the switch trigger is being pulled under an un-operable condition. Make sure to pull the switch trigger only after the main power switch is turned on and the chain brake is released.

      Erica MillerAug 23, 2025
      Your Makita Chainsaw might not start due to several reasons: First, ensure that two charged battery cartridges are properly installed. Second, the battery voltage may be low, requiring you to recharge or replace the battery cartridges. Finally, check if the main power switch is turned off, as the chainsaw automatically turns off after a period of inactivity. Turn the main power switch on again.
