Danger
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 de-
pends on several factors:
–
Proneness to blood circulation defi-
ciencies (cold, numb fingers).
–
Low ambient temperature. Wear
warm gloves to protect hands.
–
A firm grip impedes blood circula-
tion.
–
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
fingers) please consult a physician.
CAUTION
Clean engines only at places with cor-
responding oil separators (environ-
mental safety).
The appliance can be operated in a
vertical or horizontal position.
NOTICE
The appliance is equipped with a pres-
sure switch. The motor starts up only
when the lever of the pistol is pulled.
Device with hose drum:

tally from the hose drum.

Unlock the trigger gun and pull the
lever of the gun.

ing.
