Check the oil level in the high-pressure pump
ATTENTION
Milky oil
Device damage
If the oil is milky, inform authorized Customer Service
immediately.
1. Place the device on a flat and level surface.
2. Check the high-pressure pump oil level at the oil lev-
el display.
The oil level must be in the middle of the oil level in-
dication.
3. Top up the oil if necessary.
Installing accessories
Note
The EASY!Lock system connects components quickly
and safely via a single turn of the quick-release thread.
1. Connect the spray lance to the high-pressure gun
and hand-tighten (EASY!Lock).
2. Plug the high-pressure nozzle onto the spray lance.
3. Fit the union nut and hand-tighten (EASY!Lock).
4. Connect the high-pressure hose to the high-pres-
sure gun and high-pressure connection of the de-
vice and tighten hand-tight (EASY!Lock).
System care
Define system care
Note
RM 110 prevents calcification of the heating coil in the
presence of hard water.
Note
RM 111 prevents the formation of black water and cares
for the pump in the presence of soft water.
Water hardness (°dH) System care products to be
used
<3 RM 111
>3 RM 110
1. Determine the local water hardness via the local
supply company or with a hardness tester (order
number 6.768-004.0).
Refilling the system care
Note
The system care is not included in the scope of delivery.
● The system care is a highly effective agent for pre-
venting calcification of the heating coil when operat-
ing with calcareous tap water. This is drip-fed dosed
into the float container.
● The dosage is set to medium water hardness at the
factory. The device can be adjusted to the local wa-
ter hardness by customer service.
1. Refill the system care.
Refuelling

3. Close the tank cap.
4. Wipe up the spilt fuel.
● See the "Technical data" for the connected loads.
Note
The water supply hose is not included in the scope of
delivery.
1. Connect the supply hose (minimum length 7.5 m,
minimum diameter 3/4") to the water connection of
the device and to the water supply (e.g. water tap).
2. Open the water inlet.
Electrical connection
DANGER
Unsuitable electrical extension cables
Electric shock
Only use approved and appropriately marked electrical
extension cables with a sufficient line cross section for
outdoors.
Make sure that the plug and coupling of an extension
cable used are watertight.
Always unroll extension cables completely.
● For connected loads, see technical data and type
plate.
● The electrical connection must be carried out by an
electrician and comply with IEC 60364-1.
● Check the correct polarity of the device, see opera-
tion / polarity inverter switch.
DANGER
Flammable fluids
Risk of explosion
Do not spray inflammable liquids.
DANGER
Operation without spray lance
Risk of injury
Never operate the device without the spray lance installed.
Before each use, check that the spray lance is firmly
seated. The screw connection of the spray lance must
be tightened hand tight.
DANGER
High pressure water stream
Risk of injury
Never fasten the trigger in the actuated position.
Before doing any work on the device, secure the high-
pressure gun by pushing the safety latch forward.
Hold the high-pressure gun and spray lance with both
hands.
DANGER
Danger due to damaged mains cable
Electric shock
Make sure that the mains cable is not in contact with the
burner (hot) during operation.
ATTENTION
Operation with an empty fuel tank
Destruction of the fuel pump
Never operate the device with an empty fuel tank.
Changing nozzles
1. Switch off the device and operate the high-pressure
gun until the device is depressurized.
2. Lock the high-pressure gun by pushing the safety
