Maintenance - Makita 6951 Betriebsanleitung

Operation (Fig. 5)
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
trigger just as the screw bottoms out. The proper
fastening torque differs depending upon the kind or
size of screws/bolts, the type of materials to be
fastened, etc. Refer to Fig. 5 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 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 carrying out any work on the tool.
Replacement of carbon brushes (Fig. 6 & 7)
Replace carbon brushes when they are worn down to
the limit mark. Both identical carbon brushes should
be replaced at the same time.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
