Leakage, contamination or damage
If the high pressure valve is closed, you CANNOT read the pressure on the pressure gauge. You also
CANNOT read the pressure on the pressure gauge if the spray gun is connected but the trigger is not
pulled.
If the pressure gauge nevertheless shows a pressure reading, there is leakage or the non-return valve is
dirty or damaged. In that case, do the following:
1. Turn off the machine.
2. Unscrew the hose coupling.
3. Clean or replace the non-return valve.
4. Check that the O-ring is still in good condition.
5. Check that the sealing ring is still in good condition.

a year
The following parts must be maintained every 1000 hours of operation or at least once a year:
