Operation; Maintenance - Makita 6952 Instruction Manual

Hook
The hook is convenient for temporarily hanging the tool.
This can be removed without using a tool. This can be
installed on either side of the tool.
Installing and removing hook (Fig. 5)
Expand the upper part of the hook in both directions and
remove it. To install the hook, follow the removal proce-
dure in reverse.

OPERATION

Hold the tool firmly and place the point of the driver bit in
the screw head. Apply forward pressure to the tool to the
extent that the bit will not slip off the screw. Start the tool
slowly and then increase the speed gradually. Release
the switch trigger just as the screw bottoms out.
The proper fastening torque differs depending upon the
kind or size of the screw/bolt, the material of the work-
piece to be fastened, etc. Refer to Fig. 6 for the relation
between fastening time and wood screw size. (Material to
be fastened: Lauan)
NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• When fastening tool screws in a steel plate, the proper
fastening torque can be obtained in an extremely short
time (approx. 0.1 – 0.2 seconds). Turn the tool off as
soon as the impact sound is heard.
• Hold the tool pointed straight at the screw or the screw
and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.
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 deter-
mine 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 identical carbon brushes. (Fig. 7)
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. (Fig. 8)
After replacing brushes, plug in the tool and break in
brushes by running tool with no load for about 10 min-
utes. Then check the tool while running and electric
brake operation when releasing the switch trigger. If elec-
tric brake is not working well, ask your local Makita ser-
vice center for repair.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centres,
always using Makita replacement parts.
