Safety warnings

IMPORTANT - Failure to observe the following safety
rules may cause injury or damage to equipment.
6.1.1 Checks to be performed before starting up the
machine.
Before using the machine, make sure all safety
devices are positioned correctly and are in good
condition.
6.2 Prohibited operations
Adjustment, maintenance and/or lubrication may not
be performed with the machine on.
6.3 Training
All users must be suitably trained, including with hands-on
experience of the machine. This training should emphasise:
 The need for attention and concentration while working;
 Children and unfit persons must not use the machine.
Hold the trigger and wand firmly

Do not use the machine on uneven surfaces

 Do not direct the jet at animals or persons
Do not direct the jet towards live parts

Do not unplug the power plug by pulling the cable

 Do not use electrical extensions
 Do not use the machine with faulty guards
7 Using the high pressure washer
7.1 Water connection
Connect the machine to the mains water supply using a hose
with a diameter of not less than 1/2" (use the quick coupling
provided). Connect the high pressure hose to the machine
and the wand by screwing up the M22 diameter screw
couplings tightly. Mount the nozzle on the wand terminal and
the wand terminal on the trigger.
7.2 Electrical connection
Mount the plug on the cable. Plug into the power socket,
making sure the main switch on the machine and power line
are both in the OFF position.
power supply voltage and frequency required by the machine
correspond to those of the power line (check the machine
rating plate). Important: the power socket must be protected
by a differential circuit-breaker in compliance with current
regulations and standards.
7.3 Electrical boards
The electrical board in the STX model has the panel shown in
the following figure, with:
switch (general)

Boiler thermostat.

 Detergent tap
 Water pressure gauge
7.4 Tanks
Fill the tanks with the respective products: diesel (main filler),
detergent (small filler) and water softener through the filler
Important: check that the
under the object compartment lid on the cowling. Each tank
has an identification label near the corresponding filler.
7.5 Start up Open the mains water tap.
Turn the main switch on. The OK light comes on to confirm
that the machine is powered correctly. Hold the wand firmly
and turn the main switch on the appliance to the ON position.
Press the lever on the handgrip a number of times to eliminate
the air present in the circuit. When the jet is constant, set the
thermostat to the required temperature.
boiler is turned on, it may give off a little smoke caused by the
presence of air in the circuit.
Before turning the machine off, set the thermostat to OFF,
wait until the water has cooled down completely (1 or 2
minutes), then turn the main switch off.
7.6 Work method
Super and Super Plus series high pressure washers are fitted
with a Delayed Total-Stop control which shuts the machine
down a few seconds after the trigger has been released.
When the trigger is pressed again, the machine starts up
normally. The high pressure washer has a "micro-leak
control" function which shuts the machine down after repeated
start-ups caused by dripping (leaks). If this function trips, the
machine stops. To start it again, turn the main switch to OFF,
then back to ON (reset). The high pressure washer is fitted
with a "no use" function which shuts the machine down after
20 minutes of inactivity. If this function trips, the machine
stops. To start it again, turn the main switch to OFF, then back
to ON (reset). This function can be cut out, but the operation
must be performed by a qualified professional.
7.7 Pressure regulation valve
The pressure regulation valve enables water pressure to be
reduced to a maximum of about 25 bars. When this value is
decreased, the valve reduces the quantity of water to be
heated, allowing the temperature to be increased.
function enables water at temperatures of more than 100°C to
be delivered for short periods (value varies according to
model and flow rate).
temperatures, great
manipulating the jet. Important: prolonged use of high
temperatures leads to a rapid accumulation of limescale.
7.8 Washing with detergent
Open the tap on the panel and operate the lever on the
trigger. The pump automatically takes up detergent from the
tank. Spray the surface to be treated, release the lever on the
trigger, then close the detergent tap. Operate the lever on the
trigger again to begin rinsing. N.B.: detergent delivery will
continue for a few seconds after the tap has been closed due
to detergent left in the hoses. Important: do not spray
detergent onto hot surfaces and rinse within the times
recommended by the detergent manufacturer.
7.9 Indicator lights
The indicator light panel provides information on machine
operation and malfunctions.
