￿How to switch over the Power mode (P) or Save mode (S)

To set to the Power mode (P), slide the lever on the side of handle to the lower side, and to set to the Save

mode (S), slide the lever to the upper side. (Fig. 8)

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 cap is bitween “16” and “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.

￿In the work of the save mode (S), avoid the continuous screw-tightening as temperature of electronic components of the converter switch increases.

￿To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, if the tool is overloaded, the motor may

stop. However, this is not the trouble but the result of protection function. In this case, release the switch of tool and eliminate the causes of overloading.

CAUTION

￿The selection examples shown in Table 5 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 impact 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 impact driver drill at LOW (low speed) when using a machine screw.

NOTE

The use of the battery BCL1430, EBL1430, EBM1430 and EBM1830 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.
