Start with Electric Starter
Choke of the combustion engine to be pulled, respectively lever to be turned.
Speed control lever (5) in position “full load”. Starter key to be put into position
“Start” and starter push button to be pressed. As soon as it has started, open
choke until the motor is running smoothly.
Do not disconnect running motor from starter battery.
Unlock and activate spray pistol. Warm up motor for 5 minutes at low
pressure. Then increase up to working pressure by turning the adjusting wheel
on the unloader valve clockwise.
Be aware of recoil. Ensure stable foothold.
Pressure Adjustment
Working pressure can continuously be adjusted between high and low
pressure by opening and closing the handle at the double lance.
Counter-clockwise:
pressure decrease
Clockwise:
pressure increase
Pressure/Water Volume Adjustment
Pressure and water volume can continuously be adjusted according to
requirements by turning the knob at the unloader valve.
Counter-clockwise:
continuous reduction of pressure and water volume
to minimum capacity
Clockwise:
continuous increase of pressure and water volume
up to maximum capacity
Detergent Injection
Only if special injector kit is installed. The injector is activated when spray
wand is fully opened. The injection rate is 10 % of the water volume. To
achieve a lower injection rate, detergent to be diluted (e.g. 5 % requires a 1 : 1
dilution).
Fully open valve at the double lance and activate spray pistol, so activating the
injector which automatically feeds the detergent into the water stream.
Detergent to be sprayed onto the object to be cleaned from the top to the
bottom. Let it work in for several minutes. Close the valve at the double lance,
so stopping the injector, and wash the object from the bottom to the top. Keep
a spray distance of 10 – 20 cm. Detergent residues to be washed away com-
pletely. Detergent not to be sprayed onto warm surfaces or in direct sunlight.
Detergent must not dry.
Detergent line to be flushed after work by dipping detergent hose into clean
water and running the machine for one minute with the valve at the double
lance open.
