OPERATION

DANGER
– The appliance may not be operated in
explosive atmospheres.
– Place the appliance on firm, even surface.
– The high-pressure cleaner must not be
used by children. (Risk of accidents on
account of improper use of 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.
– Make sure that feet are firmly planted
and you are holding the trigger gun with
one hand and your second hand is firm-
ly gripping the insulated portion of the
spray lance before starting discharge of
water.
– Never direct the water jet on to persons,
animals, the appliance itself or electrical
components.
– Risk of injury from high-pressure jet and
unsettled dirt. Wear safety goggles, pro-
tective gloves, protective overalls and
special safety boots with foot protection.
– The jet must not be directed by the user
at him/herself or at other persons to
clean clothing or footwear.
– Do not use the device other persons are
within reach of it.
– Danger of hearing damage. Always
wear suitable hearing protection when
working with the device.
– Wheels/tyre valves must not be cleaned
with this device due to the high water
pressure.
– Do not clean materials containing as-
bestos or other health-hazardous sub-
stances.
– Pay attention to ensure that all screws
of all connecting hoses are tightened
properly.
– The lever of the trigger gun must not be
clamped tight during operation.
– Do not drive over the main cable or the
high pressure hose.
– Only work with sufficient lighting.

High pressure operation

WARNING
The water jet that is emitted from the high-
pressure nozzle results in a repulsion power
acting on the hand spray gun. Make sure that
you have a firm footing and hold the trigger
gun and the spray lance with both hands.
The shoulder support (2.639-251.0) should
be used to prevent injuries and to make
work easier at recoil pressures > 150 N.
Power nozzle
The appliance is equipped with the follow-
ing nozzles:
– Power nozzle, 15° spray angle
High pressure flat stream (15°) for large
areas of contamination.
 The working pressure can be read from
the manometer.
Note:
Always direct the high-pressure jet at the
object to be cleaned from a distance to
avoid damage from high pressure.

Interrupting operation

 Release the lever on the trigger gun.
 Use the safety catch to secure the
handgun lever.
