Installing or removing socket
002341
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.
The proper fastening torque may differ depending upon the
002357
kind or size of the bolt, the material of the workpiece to be
fastened, etc. The relation between fastening torque and fas-
tening time is shown in the figures.
M14
Hold the tool firmly and place the socket over the bolt or nut.
M12
Turn the tool on and fasten for the proper fastening time.

(S) NOTE:
• When fastening screw M8 (5/16") or smaller, carefully
002358
adjust pressure on the switch trigger so that the screw is
not damaged.
M12
• Hold the tool pointed straight at the bolt or nut.
M10 • Excessive fastening torque may damage the bolt/nut or
socket. Before starting your job, always perform a test
M8
operation to determine the proper fastening time for your
(S)
bolt or nut. Especially for the bolt smaller than M8 (5/
16"), perform the above test operation to prevent the
trouble on socket or bolt, etc.
• If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
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. When the battery cartridge is discharged almost com-
pletely, voltage will drop and the fastening torque will be
reduced.
2. Socket
• Failure to use the correct size socket will cause a
reduction in the fastening torque.
