Do not use with the clutch dial numeral between
“22” and the black line at the middle of the drill mark.
Doing so may cause damage (See Fig. 8).
7. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity
to the screw diameter. When too strong torque is
used, the screw head may be broken or be injured.
Be sure to adjust the clutch dial position according to
the screw diameter.
(2) Tightening torque indication (See Fig. 7)
The tightening torque differs depending on the type
of screw and the material being tightened.
The unit indicates the tightening torque with the
numbers “1, 5, 9 ... 21” on the clutch dial, and a black
dots. The tightening toque at position “1” is the
weakest and the torque is strongest at the highest
number.
(3) Adjusting the tightening torque (See Fig. 7)
Rotate the clutch dial and line up the numbers “1, 5, 9
... 21” on the clutch dial, or the dots, with the triangle
mark on the outer body. Adjust the clutch dial in the
weak or the strong torque direction according to the
torque you need.
CAUTION
䡬
The motor rotation may be locked to cease while the
unit is used as drill. While operating the driver drill,
take care not to lock the motor.
䡬
When setting the shift knob to “HIGH” (high speed)
and the position of the clutch dial is “17” or “22”, it
may happen that the clutch does not engaged and
that the motor is locked. In such a case, please set the
shift knob to “LOW” (low speed).
䡬
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.
䡬
Too long hammering may cause the screw broken
due to excessive tightening.
8. Switch operation
(1) Lock switch
The tool is equipped with a lock switch. To activate
the main switch lock, move the lock switch to the “
䊲
LOCK” position. Move the lock switch to the opposite
position to operate the tool. (Fig. 9)
CAUTION:
Always set the lock switch to the “
䊲
LOCK” position
when carrying or storing the tool eliminate
unintentional starting.
(2) Main switch
The main switch functions as a motor switch and
rotational direction selector switch. When the main
switch is pushed to “R” indicated on the main switch,
the bit rotates clockwise. When the main switch is
pushed to “L” indicated on the main switch, the bit
rotates counterclockwise. When the main switch is
released, the tool stops. (Fig. 10)
9. Using the light
The light lights when the light switch is pushed.
When the light switch is pushed again, the light is
turned off. (Fig. 11)
CAUTION:
Do not look directly into the light. Such actions could
result in eye injury.
10. Using in the Straight or Pistol Configuration
Use the tool in the straight configuration when using
in confined spaces. Use it in the pistol configuration
when using in other locations. Select the configuration
that best matches the tool application. When changing
the configuration, the tool will make a clicking sound
when it snaps into position. Bend (or extend) the tool
until the clicking sound is heard.
CAUTION:
When using the tool in the pistol configuration, do
not hold onto the bending portion of the tool when
returning to the straight configuration. Your finger or
other part of the hand may be pinched by the bend
ing portion resulting in possible injury (Fig. 12).
