Routine Maintenance; Maintenance Schedule - Comet FDX Xtreme Bedienungs- Und Wartungsanleitung

WARNING
• If you have to interrupt the high pressure jet and put the spray gun down, without stopping the machine,
you have to insert the safety stop (32). Operation S in Fig. 6.
CAUTION
• Do not leave the high pressure cleaner for more than three minutes in bypass (spray gun closed) if
the optional thermostatic valve has not been installed by a Specialized Technician.
• 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 (33)
pressed.
• Carry out the stop operations, explained in the engine operating and maintenance manual and
disconnect the spark plug contact (petrol engines without electrical start-up) or take the ignition key
out (43) (Diesel engines and petrol engines with electrical start-up).
• Discharge any residual pressure from the high pressure hose (30) or (59), keeping the spray gun lever (33)
pressed for a few seconds.
• Wait for the high pressure cleaner to cool down.
• Carefully rewind the high pressure hose (30) or (59) without making any kinks in it.
• Follow the instructions for decommissioning as given in the engine operating and maintenance manual.
• The high pressure cleaner must be kept in a dry, clean place paying attention not to damage the high
pressure hose. Use the rack (9) to store the delivery hose and accessories. Engage the brake (41) to
avoid any uncontrolled movements of the machine (not for FDX2).
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.
Do the operations described in the
table.
Also remember to carry out the routine maintenance jobs given in the engine operating and maintenance
manual, especially as regards to checking engine oil, the air filter and the spark plug.

ROUTINE MAINTENANCE

"S " paragraph and follow the instructions given in the following
top
• Check the 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 (not for FDX2 10/150).
• Remove all dirt and debris from the cooling fins on the engine, from the air inlet
grids, from the mechanisms and rev regulator springs (refer to the engine operating
and maintenance manual).
• Clean the water inlet filter (39).
Unscrew the water inlet hose-end fitting (11) and take the filter out (also see Fig. 7).
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.
