Routine Maintenance; Maintenance Schedule - Comet K Steel S Manual De Instrucciones

• Put the regulation valve in minimum pressure conditions, turning knob (8) (Xtreme) anticlockwise until
it goes no farther (this is only necessary for models with a 15 kW/20.4 HP motor; in fact, all the other
models are fitted with a pressure resetting regulation valve).
• Close the water supply tap or take the suction hose out of the tank.
• Drain the water from the high pressure cleaner, working it for a few seconds with the spray gun lever (22)
pressed.
• Press the push button (42) to stop the machine (Xtreme).
• Move the master switch (1) to "0" position.
• Remove the plug from the power socket.
• Discharge any residual pressure from the high pressure hose, keeping the spray gun lever (22) pressed
for a few seconds.
• Wait for the high pressure cleaner to cool down.
• Disconnect the spray gun (56) from the high pressure hose (61) and put it away using the supports (3).
• Disconnect the high pressure hose from the water outlet fitting (16), wind it up carefully, avoiding
bends, and put it away on the support (7).
• Wind the power cable up with care (6), avoiding bending it, and put it away on the support (7).
• The high pressure cleaner must be kept in a dry, clean place paying attention not to damage the high
pressure hose and the power cable. Engage the brake (20) to avoid any uncontrolled movements of
the machine.
NOTE: after a prolonged period of non-use you could find a few drops of water under the pump.
This dripping normally disappears after a few hours of use. If it does persist however, contact a Specialized
Technician.

ROUTINE MAINTENANCE

• Check the power cable, high pressure hose, fittings, spray gun and lance hose.
If one or more parts are found to be damaged do not, under any circumstances,
use the high pressure cleaner and contact a Specialized Technician
• Check pump oil level with the motor off and the machine completely cooled down.
• Use the indicator (50) (Xtreme) or the dipstick integrated in the plug (14) (all the
other models). When topping up is needed please refer to the lubricant types given
in the "Specifications and technical data" paragraph.
• clean the water inlet gasket/filter (64).
Unscrew the water inlet hose-end fitting (25) and take the filter out (also see Fig. 6).
It is normally enough to put the filter under running water or blow it with
compressed air to clean it. In the most difficult cases use a scale remover or replace
it, contacting an authorised assistance centre to buy the new filter.
• clean the water inlet filter (18).
The filter is the self-cleaning type. Check that the high pressure cleaner is connected
to the water mains and the tap is open. Turn knob (53)
dirt drains through the outlet (65). When the fluid comes through clean, turn
