Start procedure reverse start
•
Turn ignition key clockwise into position "1".
•
Take handle and carefully pull out until engagement, then strongly
pull out in order to start motor. Put handle back into initial position.
If the engine in operational state and at correct oil level does not start
after several attempts, most likely the oil pressure is poor. In this case
disconnect the cable of oil pressure switch (at the male threaded flange
of the engine oil filter) upon start-up.
As soon as the engine has started, cable of oil pressure switch to
be reconnected, as otherwise the low oil level cut-out is disabled.
Pressure/Flow Regulation
Pressure and flow rate can continuously be adjusted as required at the hand
wheel of the safety control valve.
Counter-clockwise:
continuous pressure and flow reduction to minimum
capacity
Clockwise:
continuous pressure and flow increase to maximum
capacity
When pistol is closed, machine is running in circulation mode. If
water temperature exceeds 60 °C, thermo valve (14) opens,
releases small amounts of hot water and cold water enters.
After Work
In order to reduce motor stressing, decrease working pressure by turning the
hand wheel of the safety/control valve (3).
•
Close and lock spray pistol.
•
Stop motor: Turn ignition key into position “0”.
•
Remove key in case machine is not in operation
or
unattended or remains unattended.
•
Thoroughly clean high pressure hose. In case of damage (cuts,
abrasions, kinks) replace high pressure hose for safety reasons.
•
Only original OERTZEN high pressure hoses to be used.
Otherwise Declaration of Conformity and warranty will expire.
•
Reel up high pressure hose properly without any loops.
•
Store machine and accessories in a dry, frost-protected area.
•
Drain pump completely in case of extended shut-down periods.
