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.

usage may result in damage of the anvil. This tool is
(3/8")
intended for assembly and disassembly automotive

components and is provided with 9.5 mm (3/8") anvil.
(S)
When fastening screw M8 (5/16") or smaller, carefully
adjust pressure on the switch trigger so that the screw is

not damaged.
Hold the tool pointed straight at the bolt or nut.
Excessive fastening torque may damage the bolt/nut or
socket. Before starting your job, always perform a test
operation to determine the proper fastening time for your
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.
M10 (3/8")
If the tool is operated continuously until the battery
M8 (5/16")
cartridge has discharged, allow the tool to rest for 15
5.0 (S)
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.
