Lubrication
CAUTION:
• This
Authorized or Factory Service Centers only.
This tool requires no hourly or daily lubrication because it
003237
has a grease-packed lubrication system. It should be relubri-
cated after every 6 months of operation. Send the complete
tool to Makita Authorized or Factory Service Center for this
lubrication service. However, if circumstances require that
you should lubricate it by yourself, proceed as follows.
Run the tool for several minutes to warm it up. Switch off and
unplug the tool.
Loosen the six screws and remove the handle. Note that the
top screws are different from other screws.
Disconnect the two terminals (white and black) by pulling
003240
them.
