(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
◯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.
◯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.
Table 6
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 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).
◯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.

CAUTION
◯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.
◯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
◯ 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.
