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 machine.  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, wires, etc. to clean nozzles 
as this could destroy the 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. The electrical cable 
must be well insulated and cable connector screw kept 
tight.  If the cable insulation is broken or frayed, repair 
or replace immediately.  Don't take chances with 
elctrical fire or shock.

Daily/Regular Maintenance

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

  

1.

Empty unused cleaning solution from the solution 
tank.

2.

Inspect and clean filter screen in solution tank.

3.

Flush pumping system with 1 to 2 gallons of clean 
water.

4.

After each use, rinse tank with fresh water.  Period-
ically inspect the recovery tank and decontaminate 
if necessary, using a Hospital Grade Virucide or a 
10-1 bleach to water solution.  Waste water should 
be disposed of properly.

Do not allow machine to freeze.
