Disconnect battery from power tool, take it
off your back, observe battery and contact

If the battery emits fumes, heats up, smells,
makes noises or shows signs of deforma-
tion, disconnect it from the power tool, take
it off your back, put it down and immediately
move a safe distance away. Keep children
and animals away from the work area. Keep

Take the adapter out of the power tool and
refit it. Switch on the power tool – if the light

a malfunction and must be checked by a
STIHL servicing dealer.
