Care and maintenance

You can agree on regular safety inspections or close a
maintenance contract with your dealer. Please seek ad-
vice on this.
DANGER
Danger due to the device inadvertently starting up
Risk of injury
Disconnect the spark plug connector or disconnect the
battery before performing any work on the device.
CAUTION
Risk of burns from hot surfaces
Risk of injury
Allow the device to cool down prior to all work on the de-
vice.
Maintenance intervals
1. Check the high-pressure hose for damage (danger
of bursting). Immediately replace a damaged high-
pressure hose.
2. Check the exhaust device for damage. Contact cus-
tomer service in case of damage or soot formation.
Weekly
ATTENTION
Milky oil
Device damage
If the oil is milky, inform authorized Customer Service
immediately.
1. Check the oil level of the high-pressure pump.
Monthly
1. Clean the sieve in the water connection.
2. Clean the sieve in the water shortage safeguard.
3. Clean the filter on the detergent suction hose.
Every 500 operating hours, at least annually
1. Descale the device.
2. Have the device maintained by Customer Service.

Maintenance work

Replacing the oil in the high-pressure pump
See the "Technical data" section for the oil filling quanti-
ty and type.
1. Provide a catch pan for approx. 1 litre of oil.
2. Unscrew the oil drain plug.
3. Drain the oil into the catch pan.
Note
Dispose of the old oil in an environmentally friendly
manner or hand it over to an authorised collection point.
4. Screw in the oil drain plug.
5. Slowly fill with new oil until the level is in the middle
of the oil sight glass. The air bubbles must be able
to escape.
1. Carry out maintenance work on the motor as direct-
ed in the motor manufacturer's operating instruc-
tions.
Descaling the device
Deposits accumulating in the pipelines increase the flow
resistance and the motor load becomes too high.
DANGER
Hazard due to inflammable gases
Risk of explosion
Do not smoke during the descaling process. Ensure
good ventilation.
Daily
Motor
DANGER
Acid danger
Risk of acid burns
Wear safety goggles and protective gloves.
Execution:
According to legal regulations, only approved boiler sol-
vents with a test certificate may be used for removing
deposits.
● RM 101 (order number 6.295-398.0)
1. Fill a 20 litre container with 15 litres of water.
2. Add 1 litre of scale solvent.
3. Connect the water hose directly to the pump head
and hang the free end into the container.
4. Place the connected spray lance in the container
without a nozzle.
5. Start the motor according to the operating instruc-
tions of the motor manufacturer.
6. Open the high-pressure gun and do not close it
again during descaling.
7. Set the power switch to a work temperature of
40 °C.
8. Let the device run until the work temperature is
reached.
9. Switch the device off and allow it to stand for 20 min-
utes. The high-pressure gun must remain open.
10. Then pump the device empty.
Note
For the purposes of corrosion protection and neutralis-
ing acid residues, we recommend then pumping an al-
kaline solution (e.g. RM 81) through the device via the
detergent container.
