1. Fixing the body in place
○ If a load is applied to the bit when drilling holes, the
tool may be pushed out of control in the opposite
direction by recoil.
To reduce the load applied to the bit, use a well-
sharpened bit that is appropriate for the type of work.
Place the bit straight against the surface to be drilled.
○ Try to avoid drilling holes in wood that is bent, damp,
or has many knots. Also, ensure that there are no nails
or other metal objects inside the wood.
○ When drilling existing holes to make them larger, or
when the bit goes all the way through the material, be
careful as a load may be applied to the bit.
○ Placing the side handle against a pillar, etc. while
working can prevent the tool body from jerking out of
control. (Fig. 18)

2. Slip clutch
During work, the slip clutch activates when a
large load is suddenly applied, which causes the
transmission between the motor and the bit to slip,
and the bit rotation stops. If this feature activates and
the drill rotation stops, quickly stop the switch.
NOTE
The slip clutch only activates when the change lever is
in low speed ("1").
OPERATIONAL CAUTIONS
1. Resting the unit after continuous work
(1) The power tool is equipped with a temperature
protection circuit to protect the motor.
Continuous drilling or tightening wood screw 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.
