Check the power supply cable. The cable must not be damaged (risk of electric shock). An authorised
electrician must replace the damaged power lead immediately.
-
Check high-pressure hose for damages (risk of bursting); if damaged replace immediately.
Measures at risk of frost:

7.3 Oil level high-pressure pump (check regularly)
-
Check the oil level in the crankcase before starting operation of the cleaner.
-
Check with oil dipstick.
-
Check in fresh oil tank approx. 2 cm.
-
First oil change after approx. 50 hours of operation, subsequently every 300 operating hours or every
6 months.
Oil change:
- Open oil-drain screw.
- Let oil drain off into collecting tray.
- Close oil-drain screw.
- Fill in new oil slowly, oil must reach the middle of the oil level indicator.
Applicable oil: SAE 10W-60 fully synthetic (Item.-No.: WB0011-01)
7.4 Filter
The standard water filter is on the backside of the device at the water inlet connection behind the Geka-
coupling towards the high-pressure pump.
Check the filter regularly (at least 1 x daily) and clean if applicable. Screw off the filter casing and rinse
filter.
Contaminated filters lead to water shortages and therefore damages the pump.
