OPERATIONAL CAUTIONS

Resting the unit after continuous work

(1)

The power tool is equipped with a temperature
protection circuit to protect the motor.
Continuous bolt-tightening work may cause the
temperature of the unit to rise, activating the
temperature protection circuit and automatically
stopping operation.
If this happens, allow the power tool to cool before
resuming use.

(2)

After use for continuous tightening wood screw
works, rest the unit for 15 minutes or so when
replacing the battery. The temperature of the
motor, switch, etc., will rise if the work is started
again immediately after battery replacement,
eventually resulting in burnout.

CAUTION

●

The selection examples shown in Table 6 should
be considered as general standard. As different
types of tightening screws and different materials
to be tightened are used in actual works proper
adjustments are naturally necessary.

●

When using the hammer drill with a machine
screw at HIGH (high speed), a screw may damage
or a bit may loose due to the tightning torque is
too strong. Use the hammer drill at LOW (low
speed) when using a machine screw.

NOTE:

䡬

The use of the battery in a cold condition (below 0
degree Centigrade) can sometimes result in the
weakened tightening torque and reduced amount
of work. This, however, is a temporary
phenomenon, and returns to normal when the
battery warms up.

䡬

When using the unit as an impact drill, prolonged
operation of 5 minutes or more will result in
internal heat which may cause a repeated noise
other than the sound normally emitted by the
motor. This does not indicate a malfunction.
Discontinuing use of the unit and allowing its
internal temperature to cool down will eliminate
the noise.
For prolonged use, allow the unit to cool down
periodically.

12. Using the light

Pull the trigger switch to light up the light. The
light keeps on lighting while the trigger switch is
being pulled. The light goes out after releasing the
trigger switch. (Fig. 1).

CAUTION:
Do not expose directly your eye to the light by
looking into the light.
If your eye is continuously exposed to the light,
your eye will be hurt.

13. 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.

●

Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
