Comet CLASSIC 3.11 Notice Technique - Utilisation Et Entretien page 30

• The pressure value can be modified by acting on the pressure regulator (64) of the cleaner gun (63), as
in Step H in Fig. 7 to increase the pressure, or as in Step L in Fig. 7 to decrease the pressure (EVO only).
• You can check the pressure level on the pressure gauge (13).
NOTE: If the level of fuel in the tank is below the minimum mark, the warning light (44) will remain lit, even
if you are operating the cleaner with cold water.
STANDARD OPERATION WITH HOT WATER (AT HIGH PRESSURE)
• Check the nozzle support head (30) is not set for the distribution of detergent. Also refer to
THE CLEANER WITH DETERGENT"
• 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 18 l / 4,8 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 (41).
• Press the cleaner gun lever (22) 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.
• The pressure value can be modified by acting on the pressure regulator (64) of the cleaner gun (63), as
in Step H in Fig. 7 to increase the pressure, or as in Step L in Fig. 7 to decrease the pressure (EVO only).
• You can check the pressure level on the pressure gauge (13).
• When the fuel is low, the burner will stop working and the warning light (44) 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.
(MAXIMUM PRESSURE 32 bar 464 psi - ONLY EXTRA)
The EXTRA series high pressure cleaners were designed in compliance with category II of Directive for
pressure equipment (PED). The compliance with this requirement is assured by a special electronic device
that constantly checks:
• that for temperatures above 110 °C/230 °F, the pressure set is below 32 bar/464 psi;
• that for pressures above 32 bar/464 psi, the temperature set is no greater than 110 °C/230 °F.
If the above limits are exceeded, the burner stops and the warning light (48) comes on.
Steam operation will only resume if the pressure is reduced to below 32 bar/464 psi.
• Turn the high pressure cleaner on again by turning the master switch (1) to
to below 32 bar/464 psi by turning the knob (8) anticlockwise.
• Set the temperature between 110°C/230°F and 140°C/284°F using the temperature adjustment knob (41).
• Press the cleaner gun lever (22) and wait for steam to be produced.
• If the burner stops working during use of the cleaner and the warning light (48) lights up, turn the knob (8)
anticlockwise to lower the pressure below 32 bar/464 psi.
• You can check the pressure level on the pressure gauge (13).
• When the fuel is low, the burner will stop working and the warning light (44) 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 when it reaches the set temperature.
• If the flame goes out, the burner will stop working and the warning light (49) will light up.
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".
• Check if the pressure regulator (64) is set for maximum pressure. Step H in Fig. 7 (EVO only).
