1. Unscrew the cap of the built-in detergent tank. (See G1)
2. Add detergent to the tank and screw the cap back on. (See G2)
4) Start the pressure washer by turning ON/OFF switch to ON, let the machine run for a
while to reach the necessary pressure,and then press the gun trigger (9). (See E)
REMINDER: Motor does not run continuously, only when trigger is squeezed.
3. ADJUSTING THE SPRAY
The adjustable spray nozzle can adjust from fan to jet setting. The spray is adjusted from
jet spray to fan spray by turning the nozzle as shown in F.
NOTE: the pressure of the spray on the surface you are cleaning increases as you move
the wand closer to the surface.
CAUTION: Jet spray adjustment is very aggressive. Do not adjust while spraying. We
recommend that for most cleaning applications a 20-degree spray angle should be used
to avoid damage to the surface being sprayed.
Surface preparation
Before staring any cleaning task it is important the area for objects which could create a
hazard. Remove objects from the work area which area which could be tripped over, such
as toys or outdoor furniture. Ensure that all doors and windows are closed tight.

Maintenance
WARNING! Always disconnect the electrical plug from the socket prior to
maintenance or cleaning. To ensure a long and problem free working life, please take
the following advice:
- Wash out water hose, high pressure hose, spray lance and accessories before mounting.
- Clean the connectors of dust and sand.
- Rinse the detergent spraying attachment after use.
- Clean the nozzles.
Any repair should always be made in an authorized workshop with original spare parts.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
Cleaning of water inlet filter
Clean the water inlet filter regularly once a month or more frequently according to use.
Carefully loosen the filter with a screwdriver and clean it. Check that it is intact before re-
mounting it.
The inlet filter must always be fitted inside the water inlet pipe to filter out sand, limestone
and other impurities, as they will damage the pump valves.
CAUTION: Failure to fit the filter will invalidate the guarantee.
Cleaning of nozzle
A clogging up in the nozzle causes a pump pressure which is too high. This is why cleaning
is required immediately.
1. Stop the machine and disconnect the nozzle.
2. Clean the nozzle. (See H1, H2)
IMPORTANT: The nozzle cleaning tool (18) should only be used when the nozzle is detached.
3. Flush the nozzle backwards with water.
Cleaning of machine vents
The machine should be kept clean so as to let cooling air pass freely through the machine vents.
Greasing of couplings
To ensure an easy connection and that o-rings do not dry up. The couplings should be
greased regularly.
