Operation

Danger
Risk of explosion!
Do not spray flammable liquids.
If the appliance is used in hazardous areas
(e.g. filling stations) all of the safety provi-
sions and operating instructions detailed in
this manual must be observed.
Warning
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
Proneness to blood circulation deficien-
–
cies (cold, numb fingers).
Low ambient temperature. Wear warm
–
gloves to protect hands.
A firm grip impedes blood circulation.
–
Continuous operation is worse than an
–
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
Caution
Clean engines only at places with corre-
sponding oil separators (environmental
safety).
