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.
