The pilot holes should be slightly smaller than the wood
screws in diameter.
The size of wood screw which can be fastened with this
tool may differ depending upon the type of material to be
fastened. Always perform a test operation to determine
the size of wood screw.
When fastening bolts or nuts, always perform a test
operation to verify the adequate fastening time for your
bolt or nut. Excessive fastening torque may damage the
bolt/nut or socket bit.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
when they wear down to the limit mark. Keep the carbon
brushes clean and free to slip in the holders. Both carbon
brushes should be replaced at the same time. Use only iden-
tical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take out
the worn carbon brushes, insert the new ones and secure
the brush holder caps.
After replacing brushes, plug in the tool and break in brushes
by running tool with no load for about 10 minutes. Then
check the tool while running and electric brake operation
when releasing the switch trigger. If electric brake is not
working well, ask your local Makita service center for repair.
To maintain product SAFETY and RELIABILITY, repairs, any
other maintenance or adjustment should be performed by
Makita Authorized or Factory Service Centers, always using
Makita replacement parts.
