Water Leaks
Check the water pressure pump, water hoses, and their connections.
• If water leaks from a hose connection, open it and replace the O-ring.
• If a connector leaks, replace the thread-seal tape, as follows:
1. Open the connection and remove the old thread-seal tape.
2. Wrap fresh thread-seal tape (for example,
PTFE
or
Teflon
®
tape) on the threads of the connector.
Wrap thread-seal tape clockwise, in the direction of the thread, so that it doesn’t unwrap when
tightening the connection.
3. Close and tighten the connector.
Oil
• The oil level should be no lower than the middle of the sight glass.
• With high atmospheric humidity and temperature fluctuation there might be condensation (if the oil has
a grayish color).
If the oil has a grayish color, it must be changed, as follows:
1. Make sure the WaterJet is switched off.
2. Disconnect the power cable from the wall socket.
Warning: Electrical Hazard
Contact with live circuits could cause serious electric shock. Do not continue before
turning off the power switch and disconnecting the power cable.
3. Drain the oil into a container.
4. Refill the water pressure pump with 0.25 liters of motor oil W 15/40.

5. Dispose of the container in accordance with local regulation.
