10 Service and maintenance
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.
Information on battery packs
– Where possible, store the battery pack in a cool,
dry place at a temperature between 5 °C and 25
°C.
– Battery packs are most efficient at temperatures
between 20 °C and 30 °C.
– Protect the battery pack from moisture, water
and heat.
– Significantly shorter operating times after each
charge indicate that the battery pack is worn and
should be replaced with a new one.
– The LiIon battery pack is fully compatible with the
charger! Integrated electronics prevent over-
loading and overheating during the charging pro-
cess.
– Do not leave flat battery packs in a charger dis-
connected from the mains power supply for lon-
ger than one month. There is a risk of total
discharge and the maximum power of the battery
pack may decrease.
– Store the battery pack in its packaging to reduce
the risk of short circuits..
– If LiIon battery packs are to be stored for long pe-
riods without use, they should be charged to 40 %
capacity (approx. 15 mins. charging period).
