TSS Models - In TSS models with automatic delivery flow
cut-o system:
a. When the gun trigger is released the dynamic
pressure automatically cuts out the motor (see Fig. D);
b. When the gun trigger is depressed the automatic
drop in pressure starts the motor and the pressure
is restored after a very slight delay;
c. If the TSS is to function correctly all gun releasing
and depressing operations must be performed at
intervals of not less than 4 - 5 seconds at least.
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.
Note: To prevent damage to the appliance, do not allow
it to oper- ate 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 (Fig. D17).
Restarting
1. Release the safety catch (Fig. D17).
2. Depress the gun trigger and discharge the residual
air inside the hoses.
3. Set the starter device on (ON/I).
Storage
1. Switch the appliance off (OFF/0).
2. Remove the plug from the socket.
3. Turn o the water supply tap.
4. Discharge the residual pressure from the gun until
all the water has come out of the nozzle.
5. Drain and wash out the detergent tank at the end of
the working session. To wash out the tank, use clean
water instead of the detergent.
6. Engage the gun safety catch (Fig. D17).
Relling and using detergent
When using detergent, the adjustable nozzle must be set
on " " (on models with this feature).
Use of a high pressure hose longer than the one originally
supplied with the cleaner, or the use of an additional hose
extension, may reduce or completely halt the intake of
detergent.
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 work from 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 30cm. Do
not allow the rinse water to run onto unwashed surfaces.
In some cases, scrubbing with brushes is needed to
remove dirt. High pressure is not always the best solution
for good washing results, since it may damage some
surfaces. The finest adjustable nozzle jet setting or the
rotopower nozzle should not be used on delicate or
painted parts, or on pressurised components (e.g tyres,
inflation valves, etc.).
Effective washing depends on both the pressure and
volume of the water used, to the same degree.
MAINTENANCE (Fig. E)
Any maintenance operations not covered by this chapter
should be carried out by an Authorized sales and service
Centre.
Caution! 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 (Fig. E7).
Cleaning the filter
Inspect the intake filter (Fig. E25) and detergent filter
(if fitted) before each use, and clean in accordance with
the instructions if necessary.
Unjamming the motor
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 and lubricate the o-rings using the lubricating
grease tube (where sup- plied) as shown before storing it
away for winter.
Put the appliance in a dry place, protected from frost.
