removed from the machine.
Always hold the machine with both hands on
the designated handles, take a secure stance
and concentrate on the work.
Avoid the machine swirling up or taking in dust

8.1 Working Directions
Grinding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Rough grinding: position the machine at an angle of
30° - 40° for the best working results.
Cut-off grinding:
Always work against the run of the disc
(see illustration). Otherwise there is
the danger of the machine kicking
back from the cut out of control. Guide
the machine evenly at a speed
suitable for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
Sanding:
Press down the machine evenly on the surface and
move back and forth so that the surface of the
workpiece does not become too hot.
Wire brushing:
Press down the machine evenly.
9. Cleaning
Button (17) for adjusting the handle:
Occasionally vacuum clean the button or blow
compressed air through it (when pressed, in all 3
main handle positions). Prior to this operation,
separate the power tool from the power source and
wear protective goggles and a dust mask.
10. Transport
Transport of li-ion battery packs:
The shipping of li-ion battery pack is subject to laws
related to the carriage of hazardous goods (UN
3480 and UN 3481). Inform yourself of the currently
valid specifications when shipping li-ion battery
packs. If necessary, consult your freight forwarder.

and no fluid is leaking. Remove the battery pack
from the machine for sending. Prevent the contacts
from short-circuiting (e.g. by protecting them with
adhesive tape).
Remove the battery pack from the machine to
transport the machine.
11. Troubleshooting
The electronic signal indicator (4) lights up and
the load speed decreases. The temperature is too
high! Run the machine in idling until the electronic
signal indicator switches off.
The electronic signal display (4) flashes and
the machine does not start. The restart protection
is active. The machine will not start if the battery
pack is inserted while the machine is on. Switch the
