4.1 Environmental protection
••
• Please dispose of packaging environmentally
••
responsibly.
The packaging materials are recyclable.
Please do not throw the packaging in with
household rubbish but take it to a recycling
centre.
••
• Please dispose of scrapped units
••
environmentally-responsibly.
Scrapped units consist of valuable recyclable
materials that should be taken to a recycling
centre. Batteries, oil and similar products
must not be allowed to contaminate the
environment. Therefore, please dispose of
scrapped units via appropriate disposal
systems.
••
• Please ensure engine oil, fuel oil, diesel and
••
petrol
to contaminate the environment. Please
protect the ground and dispose of used oil
ecologically.
4. Start-up
••
• Check the oil level in the oil tank. Do not start
••
the appliance if the oil level has dropped
below “MIN”. Top up the oil as required (see
tech. data, chap. 3).
4.5 Pouring in the fuel
••
• The appliance is delivered with an empty fuel
••
tank.
••
• Fill the fuel tank with diesel or a light fuel oil
••
before the initial start-up.
– When the fuel tank is empty, the fuel
pump will operate dry and will be
damaged.
– Unsuitable fuels must not be used,
e.g. petrol (danger of explosion).
4.6 Pouring in the liquid softener
••
• The liquid softener prevents the heating
••
element from becoming calcified when
operating with hard supply water. The liquid
softener is added in drops to the supply water
in the water tank. The metering is set to an
average value at the factoy. This setting may
be adjusted to local conditions by customer
service.
4.2 Unpacking the appliance
••
• Please contact your dealer immediately if, on
••
unpacking the appliance, you discover damage
has been caused during trans-portation.

••
with pressure flow control.
••
• Connect the high-pressure hose accordingly.
••
••
• Attach the high-pressure nozzle to the spray
••
lance.
••
• Tighten all union nuts hand-tight.
••
4.4 Checking the oil level of the
high-pressure pump
••
• Before the initial start-up, open the appliance
••
hood and cut the tip off the oil tank cover
(venting the oil housing).
••
• Pour the RM 110 liquid softener (included in
••
standard delivery) into the filling orifice of the
white tank.
••
• You can also work without liquid softener
••
when operating with soft water, e.g. rain water.
In this case you should remove the small (!)
cover from the white tank and place the
supplied spring underneath on the cover
support. Then replace the cover. This prevents
the indicator light on the instrument panel from
continually flashing. This spring must be
removed when operating with supply water.

8. General Information
8.1 Safety equipment
Overflow valve with 2 pressure switches
When the water flow rate is reduced with the
servo compression valve on the hand-held spray
gun or with the flow regulator on the pump head,
the overflow valve opens and some of the water
flows back to the pump suction side.
If the gun is completely closed, enabling all of the
water to flow back to the pump suction side, the
pressure switch located on the overflow valve
switches off the pump.
If the hand-held spray gun is opened again, the
pressure switch located on the cylinder head
switches on the pump again. The overflow valve
is set and lead-sealed at the factory.
Adjustments must only be carried out by customer
service.
Safety valve
The safety valve opens when the pressure switch
is defective. The safety valve is set and leadsealed at the factory. Adjustments may only be
carried out by customer service.
Low-water safety device
The low-water safety device prevents the burner
