15. While cleaning, pre-spray traffic areas and spots using the spray wand. The
spray wand is attached to a quick disconnect and is pressurized when the
MAIN SWITCH is turned on.
WARNING:
To avoid serious injury: Disconnect power before servicing. Electrical
service must be performed by an authorized service station or electrician.
Use only nonflammable commercial chemicals intended for machine
application. Do not use where explosive vapors or dust are present in the
air. Disconnect power if the machine is left unattended. Do not allow
machine to freeze. Do not expose to rain, store machine indoors.
Daily Maintenance:
1. Rinse out the recovery tank and clean the recovery dome. In addition,
remove and clean the recovery screen cap.
2. Drain the solution tank and clean with water.
3. Remove any debris in either the recovery or solution tank.
4. Flush the pumping system with clean warm water or white vinegar.
5. Remove lint or debris from the vacuum shoe or brush. Hint: if heavy lint
build-up is present, use a hacksaw blade with teeth down to remove
the lint.
Periodic Maintenance:
x It is highly recommended that once a month you flush the Marathon 2000 out
with a 8 to 1 ratio of water to white vinegar or anti-browning solution through
the Marathon 2000
extractor. This will help to prevent the build up of alkaline
residue.
x If the spray jets become clogged, remove and wash them thoroughly and
blow dry. Do not use wire or pins to clean the nozzles as this will cause the
spray pattern to become distorted, thereby creating a streaking pattern on the
carpeting.
x If the spray jets drip after the pump is turned off, the solenoid valve may need
to be cleaned.
x Once a month, inspect all electrical cables, hoses, filters and connections in
the Marathon 2000. If you see something that should be repaired or replaced
it should be reported and repaired. Little things are easy to forget about, but
as these little things add up, you end up with a cluster of problems that will
cost you in the long run.
CAUTION: When opening the Marathon 2000 for service and/or inspection, be
sure that the recovery hose is in its proper position. If not, the hose can
become crushed and you will not get good airflow from the vacuum nozzle.
