Makita HR4013C instruction manual Maintenance, Blow-out bulb optional accessory Lubrication

CAUTION:

•There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break- through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations, and maintain good balance and safe footing. Failure to do so may result in the loss of control of the tool and potentially severe injury.

Lubrication

CAUTION:

•This servicing should be performed by Makita Authorized or Factory Service Centers only.

•Do not perform lubrication just after the operation, wait until the tool cools down. Otherwise skin burn may result.

This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. However, it is necessary to replace grease and carbon brushes periodically for tool's long life.
