CAUTION: high pressure jet of water
. Grip the lance with both hands.
Never direct the jet of water toward
people or animals.
TO START THE MACHINE IT IS NECESSARY TO FOLLOW THE FOLLOWING SEQUENCE:
1) STARTING STAGES
A) Turn on the water
B) Set to zero the pressure by turning the
regulating knob on the lance (when
present). The pressure is indicated by
the pressure gauge (FIG. C/7)
C) Press the starting switch ON
(FIG. C/5)
CAUTION: grip the lance and the
spray gun with both hands
D) Hold the gun in the open position for a
few seconds to allow the air to escape from the hoses.
E) At this point adjust the machine to your pressure requirement by turning the pressure
regulating knob on the lance (when present)
F) Select the temperature of the water by turning the starting knob of the burner
(FIG. C/4). In position 0 the burner is OFF and water is cold
2) USE
The machine can (by low pressure or even by high pressure according to models - see table
"Equipment") suck and mix detergents or other liquid chemicals (not corrosive) thanks to an
automatic device.
The machine is equipped with a detergent suction hose with filter (FIG. A/16)
The quantity of detergent can be regulated by turning the intake knob (FIG. A/7)
We suggest proceding in the following way:
- distribute the detergent on the surface to be cleaned
- stop the delivery and wait 3-4 minutes
- start the hot jet of water
To avoid chemical deposits building up we suggest to clean the chemical suction kit by sucking
water for a few seconds.
When the fuel inside the burner (gas-oil) reaches the minimum level, the warning light for lack of
gas-oil (2) lights up (only on prepared machines). In this case fill the gas-oil tank (FIG. B/21)
