Suck in water from vessel
DANGER
Never suck in water from a drinking water
container. Never suck in liquids which con-
tain solvents like lacquer thinner, petrol, oil
or unfiltered water. The sealings within the
device are not solvent resistant. The spray
mist of solvents is highly inflammable, ex-
plosive and poisonous.
 Connect suction hose (minimum diame-
ter 3/4") with filter (accessory) to the
water connection point.
 Set dosing value for detergent to "0".
 Remove air from appliance before oper-
ation.
Note:
Do not use the Geka coupling (included in
delivery) for vacuuming operations! Not all
connector couplings are suitable for vacu-
uming operations (pump sucks air and
therefore does not build up pressure).
Dearating the appliance
 Open the water supply.
 Start the engine according to the oper-
ating instructions of the engine manu-
facturer.
 To dearate the appliance, unscrew the
nozzle and allow the appliance to run
until the water exits in a bubble-free
state.
 Switch off the appliance and fit the noz-
zle again.

Operation

DANGER
– Place the appliance on firm surface.
– The high-pressure cleaner must not be
used by children. (Risk of accidents on
account of improper use of the device).
– The high-pressure jet generates high
levels of noise when the device is in
use. Risk of hearing impairment. Al-
ways use proper hearing protection
while working with the device.
– The water jet coming out of the high-
pressure nozzle causes the gun to re-
coil. Further, an angular spray pipe can
cause additional torque. Hence, hold
the spray lance and gun firmly.
– Never direct the water jet on to persons,
animals, the appliance itself or electrical
components.
– Vehile tyres/ tyre valves may be
cleaned only with a minimum spray dis-
tance of 30 cm. Otherwise, the high
pressure spray can cause damage to
the vehicle tyre/ tyre valve. The discol-
ouring of the tyre is the fhe first sign of
damage. Damaged vehicle tyres are a
source of danger.
– Do not spray materials containing as-
bestos or other health-hazardous sub-
stances.
– The operator must wear proper safety
gear to be protected against the water
sprays.
– Pay attention to ensure that all screws
of all connecting hoses are tightened
properly.
– The lever of the hand spray gun must
not be locked during the operation.
– Do not spray flammable liquids.
