Installing or removing socket
001265
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.
[*1] Presetting number of impacts is impossible for more than
200 impacts (4 seconds).
[*2] Fastening time includes when you pull the trigger com-
pletely.
CAUTION:
•
Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time and number of impacts (presetting number).
•
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 proper fastening torque may differ depending upon the

kind or size of the bolt, the material of the workpiece to be
M10 (3/8")
fastened, etc. The relation between fastening torque and fas-
(M10)
tening time is shown in the figures.

including the following. After fastening, always check the
torque with a torque wrench.
