NOTE: Loosening stuck or hard to move sleeves.
Grasp the bit installed in the keyless chuck, in a vise or similar tool.
Set the clutch dial position to “1-11” and turn on the switch. The motor then starts.
Finally, rotate the sleeve to the left, and it will loosen.
4. Confirm that the battery is mounted correctly.
5. Check the rotational direction.
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise (See Fig. 17).
(The
L
and
R
marks are provided on the body.)
When the trigger switch is depressed, the tool
rotates. When the trigger is released, the tool stops.
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.
When releasing the trigger of the switch, the brake
will be applied for immediate stopping.
6. Change rotation speed.
Operate the shift knob to change the rotational speed. Move the shift knob in the
direction of the arrow (see Figs. 18 and 19).
When the shift knob is set to “LOW”, the drill rotates at a low speed. When set to “HIGH”,
the drill rotates at a high speed.
CAUTION:
When changing the rotational speed with the shift knob, confirm 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 (operations indicated in the following chart)
set the shift knob to “LOW”. If “HIGH” is set and the unit is used, it may cause the motor
to burn out or malfunction prematurely.
