Causes and remedies:
1. Battery pack almost flat (the electronics
prevent the battery pack from discharging totally
and avoid irreparable damage).
If the battery pack is almost flat, it must be
recharged.
2. Long continuous overloading of the machine will
activate the temperature cut-out.
Leave the machine or battery pack to cool.
Note: The machine will cool more quickly if you
operate it at idling speed.
6.2
Battery pack
Charge the battery pack before use.
If performance diminishes, recharge the battery
pack.
Removing the battery pack
Press the battery pack release button (6) and
remove the battery pack (7).
To fit
Slide in the battery pack (7) until it engages.
6.3
Setting the direction of rotation,
engaging the transporting safety device
(switch-on lock)
Do not actuate the rotation selector switch or
engage the transportation lock (4) unless the
motor has stopped completely!
Actuate the rotational direction switch /
Engage the transportation lock (4)
R = Right rotation set
(insert screws)
L = Left rotation set
(remove screws)
0 = Central position: transportation lock setting
(switch-on lock)
6.4
Switching on and off
To switch on: press the trigger switch (5).
Switching off: Release the trigger (5).
6.5
Speed / Tightening torque
The speed and tightening torque are connected
directly. The lower the speed, the lower the
tightening torque.
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.
6.6
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.
7. Use
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
application:
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.
8. Accessories
Use only genuine Metabo accessories.
