Trigger switch
CAUTION
The pushing button can not be switched while
the impact wrench is turning. To switch the
pushing button, stop the impact wrench, then set
the pushing button.
5. Switch operation
○ When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
○ The rotational speed can be controlled by varying
the amount that the trigger switch is pulled. Speed
is low when the trigger switch is pulled slightly and
increases as the trigger switch is pulled more.
○ When releasing the trigger of the switch, the brake will
be applied for immediate stopping.
NOTE
A buzzing noise is produced when the motor is about
to rotate; this is only a noise, not a machine failure.
6. Tightening and loosening bolts
A hex. socket matching the bolt or nut must fi rst be
selected. Then mount the socket on the anvil, and grip
the nut to be tightened with the hex. socket. Holding
the wrench in line with the bolt, press the power switch
to impact the nut for several seconds.
If the nut is only loosely fi tted to the bolt, the bolt
may turn with the nut, therefore mistaking proper
tightening. In this case, stop impact on the nut and
hold the bolt head with a wrench before restarting
impact, or manually tighten the bolt and nut to prevent
them slipping.
7. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
