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!
Check the connecting line with mains plug for
damages. If the power cord is damaged, please
arrange immediately for the exchange by an au-
thorized customer service or a skilled electrician.
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 without
the high pressure nozzle. If the operating pres-
sure on the manometer of the machine increases
to more than 3 MPa, then the plant needs to be
decalcified. The same is applicable when an op-
erating pressure of more than 0.7 - 1 MPa is de-
tected 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 elec-
trode.
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.
Perform a safety inspection as per the applicable
national rules and regulations for liquid spray jets
of the respective country.
