The operator must use the appliance cor-
rectly. When working with the appliance, he
must consider the local conditions and pay
due care and attention to other persons, in
particular children, who are nearby.
Never leave the appliance unattended
when it is in operation.
DANGER
–Only operate the equipment with the
front cover closed.
–Risk of injury! Device, tubes, high pres-
sure hose and connections must be in
faultless condition. If they are not in a
perfect state then the appliance must
not be used.
DANGER
–The jet must not be directed at other
persons or directed by the user at him/
herself to clean clothing or footwear.
–Risk of injury from parts flying off! Fly-
ing-off fragments or objects can injure
people or animals. Never direct the wa-
ter jet on fragile or loose objects.
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 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.
DANGER
Risk of injury on account of the emanating
water jet that could be hot!
Check high pressure hose, pipe con-
nections, fittings and water jet for dam-
age every time before use.
Replace leaky components immediate-
ly and seal all leaky connection points
immediately.
Check hose coupling to ensure that it
sits firmly and is leak-proof.
ATTENTION
Risk of damage on account of dry running.
Check filling level of the detergent tank
and refill if required.
Check softener fluid level and refill if
necessary.
To open the trigger gun: Actuate the
safety lever and trigger.
To close the hand spray gun: Release
the safety lever and trigger.
