Stepless adjustment of the tightening torque:
The speed and tightening torque can be adjusted
steplessly by pressing the trigger (5) firmly or
lightly, thus adapting to working conditions.
Recommendation:
determine the correct setting
by carrying out trial screwdriving.

Changing screwdriver bit
Inserting screwdriving bit:
Slide locking sleeve
(2) forward and insert screwdriving bit as far as the
stop. Release locking sleeve (2).
Pull on the screwdriver bit to check that it is
correctly seated.
Removing screwdriving bit:
Slide locking sleeve
(2) forward and remove screwdriving bit.
Only use screwdriving bits with such plug-in
ends:
The screwdriving bit used must match the
screw.
Damaged screwdriving bits must not be
used.
Mount the machine on the screw, ensuring it is
aligned straight.
The screwdriving process has two elements:
inserting the screw
and
tightening the screw with the percussion
mechanism.
The tightening torque depends on the impact
duration.
With an impact duration of approx. 5 seconds, the
maximum tightening torque has been reached.
The torque curve depends on the type of applica-
tion:
With a hard screwdriving application (screw-
couplings in hard material such as metal),
maximum tightening torque is already reached
after a short impact duration (a).
With a soft screwdriving application (screw-
couplings in soft material such as wood), a longer
impact duration (b) is required.
Recommendation: determine the correct impact
duration by carrying out trial screwdriving.
Caution!
With
small screws,
maximum torque
can be reached even below an impact duration of
0.5 seconds.
- This is why the duration of the screwdriving
process must be monitored exactly.
- Adjust the tightening torque by pressing firmly or
lightly on the trigger (5), ensuring that the screw
is not damaged or that the screw head does not
tear off.
Use only genuine Metabo accessories.
For dealers to select the correct accessory, they
need to know the exact model designation
of your tool.
