8.3 Working Directions
Grinding and sanding operations:
Press down the machine evenly on the surface and
move it 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 the
machine may kick back from the cut in
an out of control manner. 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.
Wire brushing:
Press down the machine evenly.
9. Cleaning
Remove the battery pack from the machine before
making any adjustments, changing tools,
maintaining or cleaning.
Clean the dust filter regularly: remove and clean
with a jet of compressed air.
Remove the battery pack periodically and wipe the
contact area of the battery pack and machine with a
dry cloth and remove deposits. If the battery pack
cannot be removed: see the Repairs chapter.
Particles may become deposited inside the power
tool during operation. This impairs the cooling of the
power tool. Conductive build-up can impair the
protective insulation of the power tool and create an
electrical hazard.
The power tool should be cleaned regularly, often
and thoroughly through all front and rear air vents
using a vacuum cleaner or by blowing in dry air.
Prior to this operation, separate the power tool from
the power source and wear protective glasses and
a suitable dust mask. Ensure appropriate suction is
available when blowing out vents.

10. Troubleshooting
The electronic signal display (13) flashes
and the machine does not start.
The battery pack is empty; the temperature is
too high or the restart protection has triggered.
Switch the machine off and back on again.
The machine will not start if the battery pack is
inserted while the machine is on.
When using a battery pack that is not part of CAS,
the machine will not start.
The electronic signal display (13) is
permanently on.
There has been an overload while working,
therefore the performance may be reduced
temporarily. Reduce working pressure.
Electronic safety shutdown: the machine has
SHUT DOWN by itself. If the slew rate of the
current is too high (for example, if the machine
suddenly seizes or kickback occurs), the machine
switches off. Switch off the machine. Switch it on
again and continue to work as normal. Try to
prevent the machine from seizing. See Section 4.2.
