Make sure that the hose is at least Ø 13 mm and that it is
reinforced.
Adjustment information (fig.3)
Adjusting the spray nozzle
(for models with this feature)
•
Water flow is adjusted by regulating the nozzle (E).
Adjusting the detergent
(on models with this feature)
•

Information on use of the appliance (fig.4)
Controls
•
Starter device (H).
Set the starter switch on (ON/1) to:
a) Start the motor (in models without TSS device);
b) Set the motor ready to start (in models with TSS
device).
•
If there is a pilot light on the starter device, it should light
up.
•
If the "low/high" settings are available, use them as
follows:
•
Low : low pressure washing
•
High : high pressure washing
•
Set the starter device switch on (OFF/0) to shut down
the appliance.
•
If there is a pilot light on the starter device, it should go
out.
•
Water jet control lever (I).
Caution - Danger!
During operation the appliance must be positioned as shown
in fig. 4 on a sturdy, stable surface.
Start-up
1) Turn on the water supply tap fully.
2) Release the safety catch (D).
3) Depress the gun trigger for a few seconds and start up
the appliance using the starter device (ON/1).
Caution - Danger!
Before starting up the appliance check that the water supply
hose is connected properly; use of the appliance without
water will damage it; do not cover the ventilation grilles when
the appliance is in use.
TSS models - In TSS models with automatic delivery flow
cut-off system:
•
When the gun trigger is released the dynamic pressure
automatically cuts out the motor (see fig.4);
•
When the gun trigger is depressed the automatic drop in
pressure starts the motor and the pressure is restored
after a very slight delay;
•
If the TSS is to function correctly all gun releasing and
depressing operations must be performed at intervals of
less than 4-5 seconds.
•
On three-phase models for professional use, at first use
start the appliance for a very short time to check that the
motor is running in the correct direction. If the motor fan
is turning anti-clockwise, exchange two of the three
phase wires (L1, L2, L3) in the electrical plug.
•
To prevent damage to the appliance, do not allow it to
operate dry and when running do not stop the water jet
for more than 10 minutes at a time (for models without
TSS device).
Stopping the appliance
1) Set the starter device switch on (OFF/0).
2) Depress the gun trigger and discharge the residual
pressure inside the hoses.
3) Engage the gun safety catch (D).
