PERIODIC MAINTENANCE
Twice a month, 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. If spray jets
become clogged, remove the spray tips, wash
them thoroughly, and blow-dry.
NOTE: Do not use pins, wire, etc. to clean
nozzles as this could destroy spray pattern.
Periodically inspect all hoses, electrical cables
and connections on your machine. Frayed or
cracked hoses should be repaired or replaced
to eliminate vacuum or solution pressure loss. If
the cable insulation is broken or frayed, repair
or replace it immediately. Don't take chances
with electrical fire or shock.
