CAUTION
When the selector switch is in the center position,
the trigger switch cannot be pulled. Always
set the selector switch to the center position
or remove the battery pack before performing
maintenance, changing accessories, storing the
tool and any time the tool is not in use.
5. Change rotation speed.
Change lever
Push-button
Change the rotational speed by turning the change
lever while pressing the push-button. Set the ▲ mark
position of the change lever to that of the rotation
speed to be used. (See Fig. 14)
When the change lever is set to "1", the drill rotates at
a low speed. When set to "2", the drill rotates at a high
speed.
CAUTION
● When changing the rotational speed with the
change lever, confi rm that the switch is off .
Changing the speed while the motor is rotating
will damage the gears.
● When a large force is required for operation set
the change lever to "1". If "2" is set and the unit
is used, it may cause the motor to burn out or
malfunction prematurely.

● To operate the change lever, press the push
button, and release the lock of the change lever.
Also, check and make sure after operation
that the push button has returned and that the
change lever has been locked.
● Switch the change lever without mistake.
If it is used at a position halfway, there is a fear
that the service life of the switching mechanism
may be shortened.
6. Confi rm that the battery is mounted correctly.
CAUTION
Until the battery locks in place with a little click,
if not, it may accidentally fall out of the tool
causing injury to you or someone around you.
7. Switch operation
○ When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
When releasing the trigger of the switch, the brake will
be applied for immediate stopping.
○ The rotational speed of the drill 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.
CAUTION
● The motor rotation may be locked to cease while
the unit is used as drill. While operating the angle
drill, take care not to lock the motor.
● If the motor is locked, immediately turn the power
off . If the motor is locked for a while, the motor or
battery may be burnt.
● A buzzing noise is produced when the motor
is about to rotate; This is only a noise, not a
machine failure.
CAUTION
● Do not apply excessive force during operation.
Doing so will not only damage the tip of the drill
bit, but also reduce the service life of the power
tool.
● When drilling holes with a hole saw, the larger
the diameter is, the larger the reactive force
applied to your arm becomes.
To prevent loss of control from the reactive
force, ensure that you have fi rm footing, support
the tool fi rmly with both hands, and drill holes
perpendicular to the drilled material.
Pressing with excessive force or prying can
cause loss of control from the reactive force,
which may damage the blade tip of the hole saw
or result in injury. Additionally, doing so makes
the tool more likely to be stopped by the overload
protection.
