CAUTION
⅜ The selection examples shown in Table 7 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.
⅜ When using the driver 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 driver drill at LOW (low speed)
when using a machine screw.
NOTE
The use of the battery EB9H, EB926H, EB930H,
EB1222HL, EB1226HL and EB1230HL 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.
6. Using the hook
CAUTION
⅜ When using the hook, pay sufficient attention so that
the main equipment does not fall. If the tool falls,
there is a risk of accident.
(3) Adjusting the tightening torque
Rotate the clutch dial and line up the numbers “1,
3, 5 ... 22” 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
⅜ 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.
⅜ Too long hammering may cause the screw broken
due to excessive tightening.
3. Change rotation speed
Operate the shift knob to change the rotational
speed. Move the shift knob in the direction of the
arrow (See Figs. 7 and 8).
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.
Use Clutch Position
Rotating speed selection (Position of the shift knob)
LOW (Low speed) HIGH (High speed)

CAUTION
⅜ 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.
⅜ 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).
⅜ 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.
