SAFETY DEVICES

• Amperometric protector.
  This safety device stops the high-pressure cleaner in the event of electrical overcurrent.
  If it trips, follow the instructions below:
  – turn the main switch (1) to “0” and take the plug out of the mains socket;
  – press the cleaner gun lever (24) to discharge any remaining pressure;
  – wait 10 to 15 minutes for the high pressure cleaner to cool down;
  – check that the requirements for the mains power connections have been followed correctly (see the INSTRUCTIONS MANUAL – SAFETY INSTRUCTIONS), paying particular attention to the extension lead used;
  – reconnect the plug and repeat the start-up procedure described in “OPERATION”.

• Safety valve.
  This duly calibrated maximum pressure valve discharges any excess pressure should an anomaly develop in the pressure adjustment system.

• Boiler safety thermostat.
  This stops the burner working should the hydraulic circuit overheat as a result of an anomaly in the temperature adjustment system.

• Burner Control.
  This stops the burner working should the combustion flame go out.

• Pressure control/ adjustment valve
  This valve is calibrated by the Manufacturer so that the operating pressure can be adjusted using the knob (8). It enables the pumped liquid to return to the pump’s suction unit, preventing the development of dangerous pressure levels when the gun is closed or when a pressure value is set over the maximum level allowed.

• Dry-running control.
  This prevents the possibility of the burner running without water.

• Gun Lever Blocking Device.
  This safety device (27) allows to lock the lever (24) on the cleaner gun (15) in the closed position, preventing accidental activation (Fig.3, position K).

• various types of lances and nozzles.

INSTALLATION – FITTING THE ACCESSORIES

• Connect the quick fit connector (22) on the hose (21) to the water outlet connector (12) and secure the ring nut tightly by hand. STEP B IN FIG. 9.
• Screw the connector (19) on the high pressure hose onto the thread of the cleaner gun (15) and tighten it using two 22 mm spanners (not supplied). STEP A IN FIG. 9.
• Insert the seal (34) onto the water inlet hose support (35) and screw it onto the connector (13). STEP C IN FIG. 8.

PRELIMINARY OPERATIONS

• Use the handles (2) to move the high pressure cleaner to the area where it is to be used.
• Engage the brake (11). STEP S IN FIG. 6
• Unwind the high pressure hose completely (211).
• Use a collar clamp (not supplied) to secure a hose from the water supply, whose internal diameter mustbe 19 mm / 0.75”, to the water inlet hose support (35). STEP C IN FIG. 8.
• Connect the water supply hose to a tap.
• Open the water tap (if connecting to the mains water supply, you must use a backflow hydraulic device:please refer to the relative instruction manual), making sure that there is no dripping (or place the suction pipe in a draft tank).
• Check the detergent adjustment knob (20) is closed properly.
• Check the master switch (1) is set at “0” and connect the plug. STEP D IN FIG. 10.
• Turn the master switch (1) to .
• Press the cleaner gun lever (24) and wait for an even stream of water to be produced.
• Turn the master switch (1) to “0” and connect the lance pipe (16) to the cleaner gun (15), securing it firmly. STEP E IN FIG. 9.

STANDARD OPERATION WITH COLD WATER (AT HIGH PRESSURE)

• Turn the high pressure cleaner on again by turning the master switch (1) to .
• Press the cleaner gun lever (24) and check the nozzle spray is even without dripping.
• If necessary, adjust the pressure using the knob (8). Turn it clockwise to increase the pressure; turn it anticlockwise to reduce the pressure.
• You can check the pressure level on the pressure gauge (10).
  NOTE: If the level of fuel in the tank is below the minimum mark, the warning light (28) will remain lit, even if you are operating the cleaner with cold water.

STANDARD OPERATION WITH HOT WATER (AT HIGH PRESSURE)

• Unscrew the cap (7) and fill the tank with automotive gas oil, making sure the fuel does not spill over.We recommend using a funnel reserved exclusively for this purpose (maximum tank capacity 20 l / 5,3 US gal). Replace the cap.
• Turn the high pressure cleaner on again by turning the master switch (1) to .
• Select the temperature required using the temperature adjustment knob (25).
• Press the cleaner gun lever (24) and check the nozzle spray is even without dripping.
• If necessary, adjust the pressure using the knob (8). Turn it clockwise to increase the pressure; turn it anticlockwise to reduce the pressure.
• You can check the pressure level on the pressure gauge (10).
• When the fuel is low, the burner will stop working and the warning light (28) will light up.
• The burner will only start working approximately 3 seconds after the cleaner gun has been opened and will stop working when the cleaner gun is closed or after it has reached the set temperature.
• If you want to switch from hot water operation to cold water operation, turn the master switch (1) to the position.

OPERATION WITH DETERGENT

The Manufacturer recommends the use of detergents which are at least 90% biodegradable.
Refer to the label on the detergent for instructions on how to use it.

• Turn the master switch (1) to “0” .
• Put the hose (37) in the external tank (FIG. 4) which has already been prepared with detergent to the strength required: in this case too, follow the instructions given for the dosage on the detergent pack label.
• Turn the knob for adjusting the detergent (20) anticlockwise.
• Switch the cleaner on again by turning the master switch (1) to or ; operate the cleaner gun lever (24) to start distribution of detergent (these versions distribute the detergent at high pressure).

STOPPING THE CLEANER – TOTAL STOP MODE

• Release the cleaner gun lever (24) to stop the high pressure jet and the high pressure cleaner moves to by-pass operating mode, and if it remains in this condition it will stop automatically after approximately 13 seconds (Total Stop).

• The cleaner will resume normal operation the as soon as the lever on the gun is pressed.
  WARNING

• If you stop the high pressure jet and put the gun down, enable the locking handle (27). STEP K IN FIG. 3.

STOPPING

• Run the cleaner for a few minutes with cold water.
• Close the tap on the water supply off completely (or remove the suction pipe from the draft tank).
• Drain the water out of the cleaner by running it for a few seconds with the cleaner gun lever (24) pressed.
• Turn the master switch (1) to “0”.
• Take the plug out of the power socket.
• Eliminate any remaining pressure in the high pressure hose (21) by keeping the cleaner gun lever (24) pressed down for a few seconds.
• Wait for the cleaner to cool down.

STORAGE

• Wind up the high pressure hose (21) with due care, making sure it is not bent.
• Wind up the power cord (6).
• Store the high pressure cleaner in a clean, dry place. Make sure the power cord and the high pressure hose are not damaged.

ROUTINE MAINTENANCE

Follow the instructions for “STOPPING WORK” and those provided in the table below.

hose, the connectors, the cleaner gun and the lance pipe.
Should any of these look damaged, do not use the cleaner for any reason and contact a QUALIFIED TECHNICIAN.
Once a Week| •  Check the water inlet filter and clean it if necessary. Unscrew the whole filter and remove the filter cartridge.
Running water or compressed air is generally all that is needed to clean the filter cartridge. In difficult cases, use a lime scale remover or replace the filter cartridge. For tough cases, use a lime scale remover or replace it by contacting a QUALIFIED TECHNICIAN to buy the spare part.
Replace the filter.
Once a Month| •  Clean the nozzle.
To clean the nozzle, it is generally sufficient to insert the pin (18) supplied into the nozzle’s hole. If no appreciable results are obtained, contact a QUALIFIED TECHNICIAN to buy the spare part . The nozzle can be replaced using a 14 mm/0.55” spanner (not supplied).
•  Check the pump oil level.

SUPPLEMENTARY MAINTENANCE
Supplementary maintenance should only be carried out by a QUALIFIED TECHNICIAN, following the table below (guideline only).

•  Check the pump is firmly secured
•  Adjust the electrodes| •   Clean the fuel nozzle.
•   Check/replace the fuel filter.
•   Check/replace the water filter
Every 500 hours| •  Change the pump oil
•  Replace the electrodes
•  Replace the fuel nozzle.
•  Check the pump delivery/suction valves.
•  Check the tightness of pump screws.| •   Check the pump’s adjustment valve
•   Clean the boiler.
•   Check the safety devices
