change lever is slid fully to the desired side. Select the
speed optimum for your job.
CAUTION:
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and incon-
sistent fastening torque and/or damage to the bolt or nut.
Installing or removing socket
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.
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.
