and the type of surface to be treated. After using
a detergent, the detergent intake circuit must be
flushed out with clean water.
NOTE
Detergent must only be delivered in the low-pres -
sure setting.
1. Prepare the solution of detergent at the con-
centration most suitable for the type of dirt
and the surface that is to be washed and fill the
detergent tank with the diluted product (Fig.
10).
2. Start the cleaner, turn on the detergent tap,
and spray the dirty surface with the diluted
product, working from bottom to top. Let it re -
act for a few minutes.
3. Rinse the whole surface well from top to bot -
tom with hot or cold water at high pressure.
4. After use with detergent, flush out the intake
circuit by placing the detergent suction hose in
a tank of clean water and letting the pump run
for 1 minute with the dosing tap turned fully on
and the lance in detergent delivery condition.
Water softener
Depending on the model, a water softener solu -
tion tank may be available. To fill the tank (Fig. 19),
use only products recommended by the manufac -
turer and/or dealer. Follow the instructions given
on the packaging meticulously. (Do not disperse
water softener in the environment).
Stopping the machine
1. Turn the burner off by rotating the pressure reg -
ulator to the “0” position.
2. Let the pressure washer run with cold water only
for at least 30 seconds to cool down the boiler.
3. Stop the pressure washer by turning the “On-
Off” switch to pos. "0".
4. Discharge the pressure from the high pressure
hose by pressing the trigger on the gun.
5. Disconnect the machine from the mains electric -
ity supply.
6. Turn off the water supply tap.
WARNING
Dry use of the water cleaner causes serious damage
to pump gaskets. If the pressure washer is left, even
temporarily, turn it off by using the switch or by un -
plugging the plug from the socket.
PRECAUTIONS AGAINST FROST
The cleaner must not be exposed to frost. If the
machine is left in premises where it is exposed to
frost, when work is over or for storage, antifreeze
must be used to prevent serious damage to the
hydraulic circuit:
1. Turn off the water supply, disconnect the hose
and run the cleaner until it is completely empty.
2. Stop the machine with the “On-Off” switch in
the “O” position.
3. Prepare a container with the solution of anti-
freeze.
4. Immerse the tube in the container with the an -
ti-freeze solution (Fig. 13).
5. Start the machine with the “On-Off” switch in
the “I” position.
6. Let it run until antifreeze comes out through
the lance.
7. Suck up antifreeze with the detergent intake
system too.
8. Disconnect the machine from the mains elec -
tricity supply.
NOTE
For high pressure cleaners provided with water tank,
the detergent solution prepared must be poured di -
rectly into the water tank.
NOTE
Anti-freeze may cause environmental pollution. Al -
ways follow the instructions given on the pack.
