at temperatures outside the specified range may damage the battery and increase the
risk of fire.
Service
Have your power tool serviced by a qualified repair person using only identical
u
replacement parts. This will ensure that the safety of the power tool is maintained.
Never service damaged battery packs. Service of battery packs should only be per-
u
formed by the manufacturer or authorized service providers.
Safety Warnings for Sander
Only use the power tool for dry sanding. Water entering a power tool will increase
u
the risk of electric shock.
Warning: Danger of fire! Avoid overheating the workpiece and the sander. Al-
u
ways empty the dust collector before taking a break from work. Sanding dust in
the dust bag, microfilter, paper bag (or in the filter bag or vacuum cleaner filter) can
spontaneously combust under certain conditions, for example if flying sparks are cre-
ated when sanding metals. This risk is increased if the sanding dust is mixed with
paint or polyurethane residue or with other chemical substances and if the workpiece
is hot as a result of prolonged work.
Clean the air vents on your power tool regularly. The motor's fan will draw the dust
u
inside the housing and excessive accumulation of powdered metal may cause elec-
trical hazards.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is
u
held more secure than by hand.
Always wait until the power tool has come to a complete stop before placing it
u
down.
In case of damage and improper use of the battery, vapours may be emitted. The
u
battery can set alight or explode. Ensure the area is well ventilated and seek med-
ical attention should you experience any adverse effects. The vapours may irritate the
respiratory system.
Do not open the battery. There is a risk of short-circuiting.
u
The battery can be damaged by pointed objects such as nails or screwdrivers or
u
by force applied externally. An internal short circuit may occur, causing the battery
to burn, smoke, explode or overheat.
Only use the battery with products from the manufacturer. This is the only way in
u
which you can protect the battery against dangerous overload.
