HOW TO USE

1. Operation of switch (Fig. 5)
The switch 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.
CAUTION:
Be sure to turn the switch OFF and wait until the motor completely stops before
changing the direction of wrench revolution. Switching while the motor is rotating
will result in burning the motor.
2. 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 preventing 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.
