Collect the generated particles at the source, avoid
deposits in the surrounding area.
Use suitable accessories for special work. In this
way, fewer particles enter the environment in an
uncontrolled manner.
Use a suitable extraction unit.
Reduce dust exposure with the following measures:
- Do not direct the escaping particles and the
exhaust air stream at yourself or nearby persons
or on dust deposits.
- Use an extraction unit and/or air purifiers.
- Ensure good ventilation of the workplace and
keep it clean using a vacuum cleaner. Sweeping
or blowing stirs up dust.
- Vacuum or wash protective clothing. Do not blow,
beat or brush.

5. Use
5.1 Multifunctional monitoring system
of the machine
If the machine switches off automatically, the
machine electronics have activated automatic
protection mode. A warning signal sounds
(continuous beeping). The beeping stops after a
maximum of 30 seconds or when the trigger (8) is
released.
In spite of this protective function, overloading
is still possible with certain applications and
can result in damage to the machine.
Causes and remedies:
1. Battery pack almost flat (the electronics
prevent the battery pack from discharging totally
and avoid irreparable damage).
If one LED (13) is flashing, the battery pack is
almost flat. If necessary, press the button (14)
and check the LEDs (13) to see the charge level.
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.
3. If the current is too high (for example, if the
machine seizes continuously for long periods),
the machine switches off.
Switch off the machine at the trigger switch (8).
Then continue working as normal. Try to prevent
the machine from seizing.
5.2 Battery pack
Charge the battery pack before use.
If performance diminishes, recharge the battery
pack.
The ideal storage temperature is between 10°C and
30°C.
In case of Li-Ion battery packs with capacity and
signal display (13) (equipment-specific):
- Press the button (14), the LEDs indicate the
charge level.
- If one LED is flashing, the battery pack is almost
flat and must be recharged.
Removing and inserting the battery pack
Removal: Press the battery pack release button
(11) and pull the battery pack (12) forwards.
Insertion: Slide the battery pack (12) in until it
engages.
5.3 Setting the direction of rotation,
engaging the transporting safety device
(switch-on lock)
Do not activate rotation selector switch (7)
unless the motor has completely stopped!
Actuate the rotation selector switch (direction of
rotation setting, transporting safety device) (7).
See page 2:
R = Clockwise setting
L = Counter-clockwise setting
0 = middle position: transportation safety device
