Holding The Tool; Maintenance; Replacing Carbon Brushes - Makita TD0101 Instruction Manual

NOTE:
• 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.

Holding the tool

Hold the tool only by the handle when performing an
operation. Do not touch the metal part.
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. The relation between fas-
tening torque and fastening time is shown in the figures.

Fastening time
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 and turn
the tool on to start operation.

NOTE:
• Use the proper bit for the head of the screw/bolt
that you wish to use.
• When fastening screw M8 or smaller, carefully
adjust pressure on the switch trigger so that the
screw is not damaged.
• Hold the tool pointed straight at the screw.
• If you tighten the screw for a time longer than
shown in the figures, the screw or the point of
the driver bit may be overstressed, stripped,
damaged, etc. Before starting your job, always
perform a test operation to determine the proper
fastening time for your screw.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. Driver bit or socket bit
Failure to use the correct size driver bit or socket
bit will cause a reduction in the fastening torque.
2. Bolt
• Even though the torque coefficient and the class
of bolt are the same, the proper fastening torque
will differ according to the diameter of bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class
of bolt and the bolt length.
3. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.
4. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
