PROTECT FROM FREEZING
If it becomes necessary to store in temperatures that
could drop below 40°F, the pumping system, hoses
and valves must be protected from freezing with a
methyl hydrate window washer antifreeze solution.
NOTE: Do not use ethylene glycol or cooling system
antifreezes.
1. Add one gallon of window washer antifreeze to
the supply tank.
2. Turn on pump switch and spray until the
antifreeze solution fills the solution lines.
3. Drain the leftover antifreeze from the supply tank.
Always allow the unit to reach room temperature
before filling with hot water or operating.
4. Before operation be sure to flush system
completely. Failure to do so after winterizing
machine will damage carpet.
DAILY/REGULAR MAINTENANCE
!
WARNING
Before making any adjustments or repairs to the
machine, disconnect the power cord from the
electrical source.
1. Empty unused cleaning solution from the
solution tank.
2. Inspect and clean filter screens in solution tank,
and on top of tube in recovery tank.
3. Flush pumping system with 1 or 2 gallons of
clean, hot water.
4. Check spray jet for full spray pattern.
5. Empty the recovery tank and rinse with clean water.
6. Check for and remove any lint or debris around
brush and vac shoe.
PERIODIC MAINTENANCE
1. After every 25 hours of operation, flush a white
vinegar solution (ONE quart vinegar to two
gallons of water) or anti-browning solution (mixed
as directed) through the extractor. This will
prevent build-up of alkaline residue in the system.
2. If the spray jet becomes clogged, remove the
spray tip, wash it thoroughly, and blow dry.
NOTE: Do not use pins, wire, etc. to clean spray jet
nozzle as this will deform the jet and destroy the spray
pattern.
3. Periodically inspect all hoses, electrical cables, filters,
gaskets and connections on your machine. Frayed
or cracked hoses should be repaired or replaced to
eliminate vacuum or solution pressure loss.
4. The electrical cable must be well insulated, if the
cable insulation is broken or frayed, repair or
replace it immediately. Don't take chances with
electrical fire or shock.
5. The filter in the bottom of the solution tank must
be clean to allow free flow of cleaning solution.
The screen filter on the vacuum tube in the
recovery tank must be free of lint buildup to
ensure full vacuum strength.
6. The dome gasket must be properly seated and
free of damage to create the air seal needed to
extract water.
