CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. Whenever carbon brushes must be replaced, they cut out the tool automatically. This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. Remove the crank cap using a Makita lock nut wrench (optional accessory). Wipe out the old grease inside and replace with a fresh grease (30 g). To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita Authorized Service Centre. The side grip swings around to either side, allowing easy handling of the tool in any position. Loosen the side grip by turning it counterclockwise, swing it to the desired position and then tighten it by turning clockwise.
