Adjusting the detergent (on models with this feature)
Detergent flow is adjusted using the regulator (F).
Adjusting the detergent pressure
Set the adjustable nozzle on " to deliver detergent at the correct
pressure (on models with this feature).
Adjusting the pressure (on models with this feature)
The regulator (G) is used to adjust the working pressure. The pres-
sure is shown on the pressure gauge (where fitted).
INFORMATION ON USE OF THE APPLIANCE (FIGA)
Controls
Starter device
Set the starter switch on (ON/I) to:
a) start the motor (in models without TSS device);
b) set the motor readyto 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 fol ows:
Low: low pressure washing
High: high pressure washing
Set the starter device switch on (OFF/O) to shut down the applian-
If there isa pilot light on the starter device it should go out.

A Caution - Danger!
/ During operation the appliance must be positioned
as shown in fig. 4 on a sturdy, stable surface.
Start-up
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.
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 tuming anti-clockwise
exchange two of the three phase wires (Ll. Q, L3) in the electrical
plug.
1) Turn on the water supply tap fully.
2) Re ease the safety catch (D).
3) Depress the gun trigger for a few seconds and start up the appli•
ance using the starter device (ON/I).
TSS models In TSS models pith automatic delivery flow cut-off
system:
when the gun trigger is released the dynamic pressure automati-
cally cuts out the motor (see fig.4};
- when the gun trigger is depressed the automatic drop in pres-
sure starts the motor and the pressure is restored after a very
slight delay;
- if the TSS is to function correctly all gun releasing and depress-
ing operations must be performed at intervals of less than 4-5
seconds.
To prevent damage to the appliance, when running do not
stop the water jet for more than 10 minutes at a time.
Stopping the appliance
1) Set the starter device sw•tch on (OFF/O).
2) Depress the gun trigger and discharge the residual pressure
inside the hoses.
3) Engage the gun safety catch (D).

Restarting
1) Release the safety catch
2) Depress the gun trigger and discharge the residual air ins'de
the hoses.
3) Set the starter device on (ON/I).
Storage
1) Switch the appliance off (OFF/O)_
2) Remove the plug from the socket.
3) Turn off the water supply tap
4) Discharge the residual pressure from the gun until all the water
has come out of the nozzle.
5) Drain the detergent tank.
6) Engage the gun safety catch
Refilling and using detergent
When using detergent, the adjustable nozzle must be set on
" : " (on models with this feature).
Fill the tank with highly degradable detergent.
Recommended cleaning procedure
Dissolve dirt by applying the detergent mixed with water to the
surface while still dry.
When dealing with vertical surfaces workfrom the bottom upwards.
Leave the detergent to act for 1-2 minutes but do not allow the
surface to dry. Starting from the bottom, use the high pressure jet
at a minimum distance of 30 cm Do not allow the rinse water to run
onto unwashed surfaces.
MAINTENANCE (FIGS)
Any maintenance operations not covered by this chapter should be
carried out by an Authorized Sa es and Service Centre.
A Caution - Danger!
Always disconnect the plug from the power socket
before carrying out any work on the appliance.
Cleaning the nozzle
1) Disconnect the lance from the nozzle.
2) Remove any dirt deposits from the nozzle hole using the tool
Cleaning the filter
Clean the suction filter (L) and the detergent fi ter after every 50
hours of operation.
Unjamming the motor (on models with this feature)
In case of lengthy stoppages, limescale sediments may cause the
motor to seize. To unjam the motor, turn the drive shaft with a
tool
End-of-season storage
Treat the appliance with non-corrosive, non-toxic antifreeze before
storing it away for winter.
