Performance
Check whether the hand-spray gun closes tightly
without any leaks. Check the protection mecha-
nism against accidental switching. Replace de-
fective hand-spray guns.
Check hoses to see if there are damages. Re-
place defect hoses immediately. Danger of acci-
dent!
If the oil is milky, it needs to be replaced.
Check oil level of the pump. Refill oil if required
(Order no. 6.288-016)
See section "Clean sieve".
Check the pump for leaks. If the leakage is more
than 3 drops per minute, call Customer Service.
Operate the machine using the spray pipe with-
out the high pressure nozzle. If the operating
pressure on the manometer of the machine in-
creases to more than 3 MPa, then the plant
needs to be decalcified. The same is applicable
when an operating pressure of more than 0.7 - 1
MPa is detected while operating the machine
without high pressure pipe (water comes out
freely at the high pressure outlet).
See section "Clean sieve".
Replace electric igniter and/or the ionisation
electrode.
Drain off oil. Fill in 1 l new oil (Order no. 6.288-
016). Check oil level in the oil tank.
Visual inspection of the plant, check high pres-
sure connections to see that they are not leaking,
check that the over-flow valves are not leaking,
check high pressure hoses, check pressure
tanks, remove calcium deposits from the heating
coil, clean/ replace ionisation electrodes, adjust
burner.
Install new hose.
Safety check according to the guidelines for fluid
spraying equipment.
