Lubrication
CAUTION:
• This servicing should be performed by Makita
Authorized 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.
