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.

10. Troubleshooting

The electronic signal display (13) flashes,
a signal can be heard and the machine
does not start. Restart protection is active.
The machine will not start if the battery pack is
inserted while the machine is on. Switch the
machine off and back on again.
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 chapter 4.2.
