Damaged safety devices and components must be
repaired or replaced in a recognised specialist
workshop, unless otherwise indicated in the oper-
ating manual.
Observe the following instructions:
– Keep the air slits on the machine and the charger
free and clean to ensure adequate cooling.
– Keep the contacts on the machine, charger and
battery pack clean.
– Check the guidance roller regularly for wear.
– Regularly remove dust deposits from the chip
guard.
– Regularly clean the base runner to prevent
scratches and cores on the surface.
Information on battery packs
– Store in a cool, dry place at a temperature be-
tween 5 °C and 25 °C.
– Protect battery packs from moisture, water and
heat.
– Do not leave flat battery packs in a charger dis-
connected from the mains power supply for lon-
ger than one month. Danger of deep discharge!
– If you intend to store li-ion battery packs for lon-
ger periods without use, you should charge them
to 40 % capacity (approx. 15 min charging time).
– To avoid short circuits the battery pack should be
stored in the packaging supplied.
– Significantly shorter operating times after each
charge indicate that the battery pack is worn and
should be replaced with a new one.
