2. Operation
Operation with high-pressure
• Open the water supply.
• Release the lever of the gun with the safety
ratchet and pull the lever.
• Turn on the machine switch.
Note: The machine is equipped with a pressure-
operated switch. The motor starts only if the lever
of the gun is pulled.
• The working pressure can be variably adjusted by
turning the spray lance on the outside (+/-).
In order to avoid damage to the surface beeing
cleaned, each time the machine is used, ensure
a minimum distance of 300 mm between the sur-
face and the spray nozzle. This distance can be
reduced dependent on the type and condition of
the surface being cleaned but is wholly at the dis-
cretion of the operator.
• The working pressure can be read off the pres-
sure gauge on the spray gun.
Operation with Detergent
• Remove the cleaning solution tank by using a
screwdriver to relieve the retaining spring.
• Fill the detergent tank (max. 1 l) with detergent.
• Reinstall the cleaning solution tank in the unit.
• Set the lowest working pressure with the spray -
lance. No detergent can be drawn in with a high
working pressure.
• Set the detergent dosing-valve to the desired
dosage rate.
• We recommend that you use detergent sparingly
for the sake of the environment. Observe the
recommended dosage on the detergent label.
• We offer you an individual cleaning and detergent
range, thereby guaranteeing fault-free work.
Please allow us to advise you or order our cata-
logue or the detergent information sheets.
Note: Only those detergents which have been
approved by the appliance manufacturer may
be used. Unsuitable detergents can damage the
appliance and the object being cleaned.
We recommend the following cleaning methods:
Step 1: Loosening dirt
Spray on detergent sparingly and leave for
1-4 minutes.
Step 2: Removing dirt
Spray off the loosened dirt with the high-pressure
spray.
Washing Brush
• Press the washing brush against the spring force
into the bayonet connection of the gun and then
turn the washing brush by 90° until you hear it
lock into position.
• The washing brush is suitable only for water tem-
peratures up to max. 40°C.
Switching Off the Machine
• After using a detergent, the machine should be
rinsed clear. To do this, set the cleaning agent
metering valve to „0“ and flush the machine for
approximately 1 minute with the gun open.
• Switch off the machine and disconnect the elec-
tric plug from the power socket.
• Close the water inlet and detach the machine
from the water connection.
• Pull the trigger until there is no more pressure in
the machine, and secure the trigger with the safe-
ty ratchet against unintentional opening.
Moving Machine
• To facilitate moving the machine, it is equipped
with a transport handle and a pair of wheels. This
allows walking while holding the unit by the top
handle, and rolling it — with negligible physical
effort — over longer distances.
• To transport the machine over steps or obsta-
cles, it must be lifted by the carrying handle.
• If the machine is to be transported horizontally,
the cleaning solution tank must be removed first.
Storing the Machine
• Insert the spray gun with spray lance into the
handgun storage clip.
• Roll up the high-pressure hose.
• Roll up the power cord, and hang it over the po-
wer cord reel holder.
• Insert the cleaning brush into the accessory
keeper.
