IMPACT WRENCH SAFETY
WARNINGS
○ Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener
may contact hidden wiring or its own cord.
Fasteners contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the
operator an electric shock.
ADDITIONAL SAFETY WARNINGS
1. When using the tool at a hight, make sure that there is
nobody below.
2. Use earplugs if using for a long time use.
3. Switch the reversing switch only after the motor has stoped
when it is necessary to change the direction of the rotation.
4. Use a step up transformer when a long extension cable
is used.
5. Confi rm the tightening torque by a torque wrench before
use in order to assertain the correct tightening torque to
be used.
6. Assemble the socket securely to the impact wrench with
the socket pin and ring.
7. Confi rm whether the socket has any cracks in it.
8. Always hold the handle and side handle of the impact
wrench fi rmly. Otherwise the counterforce produced
may result in inaccurate and even dangerous operation.

1. Switch operation (Fig. 3)
The switch (2) in this machine functions as a motor
switch and rotational direction selector switch. When
the switch is set to R indicated on the handle cover, the
motor rotates clockwise to tighten the bolt.
When the switch is set to L, the motor rotates
counterclockwise to loosen the bolt. When the switch is
released, the motor stops.
2. Operating time
The tightening torque increases when the operating time
increases. But the tightening torque does not increase
above a certain value even if the tool is driven for a long
time (See Fig. 5).
3. The protection function
To protect the tool, the protection function will be
activated, automatically shutting down the unit in the
event of any problems. (Table 1)
