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.

Before making any adjustments or repairs to the machine,
disconnect the power cord from electrical source.
