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 screws
Install the bit that matches the screw, line up the bit
in the grooves of the head of the screw, then tighten
it.
Push the angle impact driver just enough to keep
the bit fitting the head of the screw.
CAUTION:
● Applying the angle impact driver for too long
tightens the screw too much and can break it.
● Tightening a screw with the angle impact driver at
an angle to that screw can damage the head of the
screw and the proper force will not be transmitted
to the screw.
Tighten with this angle impact driver lined up
straight with the screw.
7. Tightening and loosening bolts
A hex. socket matching the bolt or nut must first 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 fitted 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.

CAUTION:
Do not look directly into the light. Such actions
could result in eye injury.
9. Battery level warning lamp
The battery level can be checked by pulling the
trigger switch while the power tool is in a no-load
state. The battery level warning lamp lights when
the battery power is very low. If this happens, charge
the battery. (Fig. 8)

NOTE:
The level at which the battery level warning lamp
lights may vary due to the ambient temperature,
characteristics of the battery, etc. and is intended
only as a guide.
The battery level warning lamp may light when the
power tool is overloaded. This does not mean that
the battery power is very low.
Be sure to check the battery level while the tool is in
a no-load state.
