Initial startup
WARNING
Damaged components
Risk of injury
Check that the device, accessories, supply lines and
connections are in perfect condition. If the condition is
not perfect, you may not use the device.
1. Apply the parking brake.
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).
Refuelling
DANGER
Unsuitable fuel
Risk of explosion
Only use diesel fuel or light heating oil. Unsuitable fuels,
such as petrol, must not be used.
ATTENTION
Operation with an empty fuel tank
Destruction of the fuel pump
Never operate the device with an empty fuel tank.
1. Open the tank cap.
2. Refill the fuel.
3. Close the tank cap.
4. Wipe up the spilt fuel.
Water connection
WARNING
Danger of backflow of contaminated water into the
drinking water network
Health risk
Observe the regulations of your water supply company.
According to applicable regulations, the device must
never be used with the drinking water network without a
system separator. Use a system separator from
KÄRCHER or a system separator as per EN 12729
Type BA. Water that has flowed through a system sep-
arator is classified as undrinkable. Always connect the
system separator to the water supply and never directly
to the water connection on the device.
● See the "Technical data" for the connected loads.
Note
The supply hose is not included in the scope of delivery.
14
Note
The system separator is not included in the scope of de-
livery.
1. Connect the system separator to the water inlet (e.g.
tap).
2. Connect the inlet hose (minimum length 7.5 m, min-
imum diameter 3/4") to the water connection of the
device and to the system separator.
3. Open the water inlet.
Suctioning water from the container
Note
Suctioning water from a container is not possible with
the RM 110 attachment kit.
DANGER
Suction of fluids containing solvents or drinking
water
Risk of injury and damage, contamination of drinking
water
Never extract fluids containing solvents such as paint
thinner, petrol, oil or unfiltered water. The seals in the
device are not resistant to solvents. The spray mist of
solvents is highly flammable, explosive and poisonous.
Never extract water from drinking water tanks.
1. Connect the suction hose (diameter at least 3/4") to
the water connection of the device.
2. Hang the suction hose in an external water source.
Note
Maximum suction height: 0.5 m
3. Until the pump draws in water: Set the pressure/
quantity regulator of the pump unit to the maximum
value.
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.
ATTENTION
Exceeding the grid impedance
Electrical shock in the event of a short-circuit
The maximum permissible mains grid impedance at the
electrical connection point (see Technical data) must
not be exceeded.
Contact your electricity supplier in the case of any un-
certainties regarding the mains grid impedance at your
electrical connection point.
● 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.
