hose and connections must be in faultless
condition. If they are not in a perfect state
then the appliance must not be used.

Operation

Safety instructions
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
– Danger of scalding by hot water! Do not
direct the water jet on persons or ani-
mals.
– Risk of burns on account of hot surfac-
es! Do not touch uninsulated pipes and
hoses when hot water operations are
on. Hold the jet pipe only at the handles.
– Risk of poisoning or itching on account
of detergent! Follow the given instruc-
tions for using detergents. Store deter-
gents safely and protect them against
access by unauthorised persons.
DANGER
Risk to life on account of electric shock! Do
not direct the water jet on the following
equipment:
– Electrical appliances and plants,
– the unit itself,
– all electricity-carrying parts in the work-
ing area.
!
There is a recoil pressure arising from the
water jet that comes out from the spray
pipe. The angular spray pipe brings about
an upward force.
DANGER
– Risk of injury! The recoil pressure of the
spray pipe can throw you off-balance.
You may fall. The spray jet can fly off
and cause damage to persons. Search
a secure place to stand and hold the
gun firmly. Never hold on tightly to the
lever of the hand spray gun.
– 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.
– Risk of accident on account of damage!
Clean tyres and valves from a minimum
distance of 30 cm.
DANGER
Danger from substances that are harmful to
health! Do not spray the following materials
as they can swirl up substances that are
harmful to health:
– Materials containing asbestos,
– Materials that could contain substances
harmful to health.
DANGER
– Risk of injury on account of the emanat-
ing water jet that could be hot! Only
original Kaercher high pressure hoses
are optimally suited for the plant. No
guarantee can be given if you use any
other hoses.
– Detergents can prove to be a health
hazard! If any detergents are added,
the water let out of the plant is not of po-
table quality.
– Risk of hearing impairment while work-
ing on noise-making parts! If so, wear
ear plugs.

Machine vibrations
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.
