1. Starting
•Please contact your dealer immediately if, on
unpacking the appliance, you discover damage
has been caused during transportation.
•Do not simply discard the packing materials
with the house-hold waste. Take the packing
materials to the appropriate collection areas for
recycling.

!Electrical Connection
•See technical data of connected values.
•Check whether the voltage shown on the rating
plate corresponds to that of the power source.
Note:
If you are using an extension cable, it
should always be completely unwound from the
cabledrumandhaveasufficientcross-sectional
area: 10 m = 1.5 mm², 30m = 2.5 mm²

"Power Switch
•With this switch you can switch the high-
pressure pump ON and OFF.

#Water Connection with coupling
•See technical data for connected values.
•Screwthecouplingontothewaterconnectionof
the appliance.
•Connect a water supply hose (not supplied) to
the appliance and the water pipe.
Suction
Observethefollowingifyouaredrawingwaterfrom
an open container:
1.Unscrewthecouplingfromthewaterconnection
of the appliance, and attach a suction hose
with filter (order no. 4.440-238) directly to the
appliance.
2.Allow the pump to operate without the high-
pressure hose until water appears at the high-
pressure outlet without any more bubbles.
3.Then re-attach the high-pressure hose.
Note:
Dirt in the feed water could lead to the ap-
pliance being damaged.To avoid this risk, we re-
commend fitting a filter. A suitable filter with 3/4"
connectionisavailableunderOrderNo.6.414-389.

%Trigger Gun with safety ratchet (A)
and high-pressure hose
•Connect the high-pressure hose to the high-
pressure outlet.
Note:
The safety ratchet does not lock the lever
of the gun during operation but only prevents it
from opening unintentionally.

&Spray lance with double nozzle
•Pushthespray lance against the spring into the
bayonet connector of the gun, and then rotate it
through 90° until it clicks into place.
•You can choose between 2 different types of
spray by rotating the front protective device on
the spray lance:
High-pressure flat spray
for large surface dirt.
Low-pressure flat spray
for cleaning with detergent
Note:
Only rotate the front protective device on
the spray lance when the gun is closed.

2. Operation
Operation with high-pressure
•Set the double nozzle to “ ”.
•Release the gun trigger with the safety ratchet
and pull the trigger.
•Switch on the pump.
Operation with Detergent
•Set the double nozzle to “ ”.
•Suspend the detergent hose in the detergent
container (not included).
•Werecommendthatyouusedetergentsparingly
for the sake of the environment.
•We offer you an individual cleaning and deter-
gent range, thereby guaranteeing fault-free
work.Pleaseallowustoadviseyouororderour
catalogue or the detergent information sheets.
Note:
Only those detergents which have been appro-
vedbytheappliancemanufacturermaybeused.
Unsuitable detergents can damage the applian-
ce and the object being cleaned.
Observetherecommendeddosageonthedeter-
gent label.
We recommend the following cleaning methods:
Step 1: Loosening dirt
Spray on detergent sparingly and allow to react
for a short time.
Step 2: Removing dirt
Sprayoffthelooseneddirtwiththehigh-pressure
spray.
•The appliance should be rinsed clean after de-
tergent has been used.To do this, suspend the
detergent suction hose in a container of clean
water, and run the pump for approx. 1 minute.
Interrupting Operation
•In the event of extended work breaks (more
than 15 minutes), switch off the pump to avoid
damage due to water overheating.
Switching Off the Appliance
•Switchoffthepumpandunplugthepowercable
from the mains.
•Close the water inlet and detach the appliance
from the water connection.
•Pullthetriggeruntilthereisnomore pressurein
the appliance, and secure the trigger with the
safety ratchet against unintentional opening.
Purpose
– Use the appliance to clean machines, vehicles,
buidings, tools etc.
– Clean facades, terrasses, garden equipment
etc. without detergent only with the high-pres-
sure spray.
– Engines may only be cleaned at locations with
appropriate oil separators (environmental
protection).
– When the appliance is used at petrol stations
and other dangerous areas, the appropriate
safety regulations must be observed.
– We recommend the dirt blaster as a special
attachment for stubborn dirt.

and rinse with water from the front.
•Cleanthestrainerinthewaterconnection.Itcan
be easily removed with a flat-nosed pliers.
Note:
Disconnect the appliance from the power mains before all repair work. Only authorized customer
service personnel may inspect electrical components.
4. Troubleshooting
Frost Protection
•Frost will destroy an appliance which has not
been completely emptied of water. Ideally, the
appliance shold be stored in a frost-free room.
In this chapter, we would like to give you some
hints on dealing with malfunctions yourself.
In all other cases or in the case of electrical faults,
please contact the authorized customer service.
Appliance does not Work
•Check the mains voltage.
•Check the connector cable for damage.
Appliance does not reach Operational
Pressure
•Adjustthedoublenozzletohighpressureorcle-
an same.
•Bleed the air from the appliance. (→Suction2.)
•Clean the strainer in the water connection.
•Check the inlet water flow rate.
•Check all inlet pipes to the pump for leaks or
blockage.
Strong Pressure Fluctuations
•Clean the double nozzle. Remove dirt from the
nozzle hole with a needle, and rinse with water
from the front.
Pump Leaks
•3 drops per minute are permissible. In the case
ofmoreseriousleakage,youshouldcontactthe
