CAUTION

䡬 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.

䡬 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.

Work Suggestions

Brick

Drilling

Wood

Use for drilling purpose.

Steel

Aluminum

Machine screw Use the bit or socket matching the screw diameter.

Driving

Wood screw Use after drilling a pilot hole.

䡬 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

䡬 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.

䡬 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).

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 In the work of the save mode (S), avoid the continuous

screw-tightening as temperature of electronic

components of the converter switch increases.

䡬 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.

5. The scope and suggestions for uses

The usable scope for various types of work based on

the mechanical structure of this unit is shown in

Table 4.
