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.
8. Change rotation speed
As shown in Fig. 9, when the rotation change lever
is slid to the lower side, the power mode (P) is set.
And when slid to upper side, the save mode (S) is

CAUTION
In the work of the save mode (S), avoid the
continuous screw-tightening as temperature of
electronic components of the converter switch
increases.
9. 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 impact driver/wrench just enough to keep
the bit fitting the head of the screw.
CAUTION
Applying the impact driver/wrench for too long
tightens the screw too much and can break it.
Tightening a screw with the impact driver/wrench
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 impact driver/wrench lined up
straight with the screw.
10. 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.
11. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
CAUTION
When using the hook, hang up the power tool
firmly not to drop accidentally.
If the power tool is dropped, it may lead to an accident.
When carrying the power tool with hooked to your
waist belt, do not fit any bit to the tip of power
tool. If the sharp bit such as drill is fitted to the
power tool when carrying it with hooked to your
waist belt, you will be injured.
