Fit the screw on the point of the bit and place the point of the
screw on the surface of the workpiece to be fastened. Apply
pressure to the tool and start it. Withdraw the tool as soon as
the clutch cuts in. Then release the switch trigger.
CAUTION:
• When fitting the screw onto the point of the bit, be careful
not to push in on the screw. If the screw is pushed in, the
clutch will engage and the screw will rotate suddenly.
This could damage a workpiece or cause an injury.
• Make sure that the bit is inserted straight in the screw
head, or the screw and/or bit may be damaged.
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
