of the screw. It depends also on the strength of material
to be fastened (wood, metal, etc.) and the type of washer
used. Operate the tool after calculating the appropriate
impact operation time by performing a trial fastening
and measuring the actually achieved torque by a torque
wrench.
WARNING: Power tool with a faulty switch is
dangerous and shall be repaired before use.
SCREWING / UNSCREWING
Install a bit that matches the screw, align the bit into the
grooves of the screw head, and then tighten it.
Push the impact driver just enough to keep the bit in con-
tact with the screw head.
WARNING: Overtightening may result in
breaking the screw or damaging the bit!
Applying the impact driver for too long may tighten the
screw too much and break it.
▪ Tightening with the impact driver not aligned with the
screw may damage the screw head and the driving
force will not be transmitted properly to the screw.
▪ Before screwing large long screws into hard material,
it is advisable to pre-drill a pilot hole with the core di-
ameter of the thread to depth approx. 2/3 of the screw
length.

Maintenance
