CAUTION

Applying the impact driver for too long tightens the screw too much and can break it.

Tightening a screw with the impact driver at an angle to that screw can damage the head of the screw and the proper force will not be transmitted to the screw. Tighten with this impact driver lined up straight with the screw.

8.Number of screw tightenings possible

Please refer to the table below for the number of screw tightenings possible with one charge.

	Screw used		No. of tightenings
	Wood screw 5/32" × 2"		Appro. 630
	(Soft wood) (ø4	× 50)	Appro. 630
	(Soft wood) (ø4	× 50)
	Machine screw		Appro. 1260
	5/16" x 5/8" (M8	× 16)	Appro. 1260
	5/16" x 5/8" (M8	× 16)

These values may vary slightly, according to surrounding temperature and battery characteristics.

OPERATIONAL CAUTIONS

1.Resting the unit after continuous work

After use for continuous bolt-tightening work, rest the unit for 15 minutes or so when replacing the battery. The temperature of the motor, switch, etc., will rise if the work is started again immediately after battery replacement, eventually resulting in burnout.

CAUTION:Do not touch the hammer case, as it gets very hot during continuous work.

2.Cautions on use of the speed control switch

This switch has a built-in, electronic circuit which steplessly varies the rotation speed. Consequently, when the switch trigger is pulled only slightly (low speed rotation) and the motor is stopped while continuously driving in screws, the components of the electronic circuit parts may overheat and be damaged.

3.Tightening torque

Refer to Fig. 15 for the tightening torque of bolts (according to size), under the conditions shown in Fig. 16. Please use this example as a general reference, as tightening torque will vary according to tightening conditions.

NOTE

If a long striking time is used, screws will be strongly tightened. This may cause the screw to break, or may damage the end of the bit.

If the unit is held at an angle to the screw being tightened, the head of the screw may be damaged, or the specified torque may not be transmitted to the screw. Always keep the unit and the screw being tightened in a straight line.
