Maintenance
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.
Daily / Regular Maintenance

machine, disconnect the power cord from electrical
source.

hot water.

cally inspect the recovery tank and decontaminate
