Place the point of the driver bit in the screw head and apply pressure to the tool. Then switch the tool on. When the clutch cuts in, the motor will stop automatically. Then release the switch trigger.

NOTE: Make sure that the driver bit is inserted straight in the screw head, or the screw and/or bit may be damaged.

Limits of fastening capacity

Use the tool within the range of the revolution angle up to 360 ﾟ. If you use the tool beyond the upper limit of this range, the clutch does not work. And the tool cannot deliver enough fastening torque (LED indicator blinks in purple slowly or lights up in purple).

NOTE:

• The revolution angle means the angle which a screw/bolt revolves when the tool attains to 100% from 50% of desired torque.
• Use of a low temperature conditioned battery cartridge may sometimes give warning for battery cartridge capacity by warning lamp and beeper which makes the tool stop immediately. In this case, the fastening capacity may be inferior to the specification on this manual even if a charged battery cartridge is used.

MAINTENANCE

• Always be sure that the tool is switched off and the battery cartridge is removed before attempting to perform inspection or maintenance.
