Operation - Makita 6953 Instruction Manual

To install the socket, push it onto the anvil of the tool until
it locks into place.
To remove the socket, simply pull it off.
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
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

The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.

Fastening time
NOTE:
• When fastening screw M8 (5/16") or smaller, care-
fully adjust pressure on the switch trigger so that
the screw is not damaged.
• Hold the tool pointed straight at the bolt or nut with-
out applying excessive pressure on the tool.
• If you fasten the bolt for a time longer than shown in
the figures, the bolt or the socket may be over-
stressed, damaged, etc. Before starting your job,
always perform a test operation to determine the
proper fastening time for your bolt. Especially for
the bolt over than M8 (5/16"), perform the above
test operation to prevent the trouble on socket or
bolt, etc.
The fastening torque is affected by a wide variety of fac-
tors including the following. After fastening, always check
the torque with a torque wrench.
1. Voltage
Voltage drop will cause a reduction in the fastening
torque.
2. Socket
• Failure to use the correct size socket will cause
a reduction in the fastening torque.
• A worn socket (wear on the hex end or square
end) will cause a reduction in the fastening
torque.
3. 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.
4. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.
