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 working 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 di-
rected by the user at him/herself to clean clothing
or footwear.
–
Risk of injury from parts flying off! Flying-off frag-
ments or objects can injure people or animals. Nev-
er direct the water 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:

Exception according to Regulation (EU) 2019/1781 Annex I Section 2 (12): a)
–
Materials containing asbestos,
–
Materials that could contain substances harmful to
health.
DANGER
–
Risk of injury on account of the emanating water jet
that could be hot! Only original Kaercher high pres-
sure 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 potable quality.
–
Risk of hearing impairment while working 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 several factors:
–
Proneness to blood circulation deficiencies (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 occurrence of the symptoms (e.g.
cold, numb fingers) please consult a physician.
Making the plant ready for operations
DANGER
Risk of injury on account of the emanating water jet that
could be hot!
DANGER
Check the high pressure hose for damage before every
use. Please arrange for the immediate replacement of a
damaged high pressure hose.
Check high pressure hose, pipe connections, fittings
and water jet for damage every time before use.
Check hose coupling to ensure that it sits firmly and
is leak-proof.

Switch-off in case of emergency
Turn the main switch to position "0".
Shut off water supply.
Activate trigger gun until device is pressure-less.
Turning on the Appliance
Open the water supply.
Turn the main switch to position "1".
Press the unlocking key.
Indicator lamp for operational readiness lights up.
Perform the cleaning operation.
Note: In case of a cleaning break of more than 30 sec-
onds, the pump will turn off. At the same time, a 6-hour
operation readiness period will be started. Within this
operation readiness period, the appliance will automat-
ically switch on because of the drop in pressure when
the hand spray gun is opened.
Getting the system ready for operations
Press the unlocking key.
Indicator lamp for operational readiness lights up.
Turn off the appliance
Turn the main switch to position "0".
Shut off water supply.
Activate trigger gun until device is pressure-less.
Secure the hand spray gun using the safety catch
so that it doesn't open accidentally.
Shutdown
If the appliance is not to be used for a longer period or
if it is not possible to install it in a frost-free environment,
you must take the following measures (see chapter
"Maintenance and care", section "Anti-freeze protec-
tion"):
