4-1
Unplug power cord(s)
before servicing or
making any repairs.
DAILY MAINTENANCE
1. Flush the entire system, including floor tool,
hand tool, etc., with 1 to 3 gallons of clean, hot
water.
2. Vacuum out the solution tank.
3. Rinse tank with fresh water. Periodically inspect
the recovery tank and decontaminate if
necessary, using a Hospital Grade Virucide or a
1-10 bleach to water solution. Wastewater
should be disposed of properly.
4. Occasionally check filter screen at the bottom of
the solution tank and rinse clean with hot water if
necessary.
5. Inspect hoses for wear. Frayed or cracked
hoses should be replaced to avoid vacuum or
solution pressure loss.
6. Inspect power cord for wear or damage. This
cable will lie on wet carpet. To prevent electrical
shock replace cords that are frayed or have
cracked insulation immediately.
7. Clean all dirt and obstructions from drain valve
and gaskets to prevent possible leakage and
premature wear.
8. Run clean water through solution pump when
work is complete.
9. Empty both tanks and rinse, run vacuum (s) for
at least one minute to dry motor(s).
10. Store with access covers removed to allow tanks
to dry.
PERIODIC MAINTENANCE
1.
Twice a month, flush a white vinegar solution
(one quart vinegar to two gallons water) or anti-
browning solution (mixed as directed) through
the extractor. This will prevent build-up of
alkaline residue in the system.
2.
If spray jet becomes clogged, remove the spray
tip, wash it thoroughly, and blow dry.

3.
Apply silicone lubricant to solution nipple.
4.
Periodically inspect all hoses, electrical cable
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 on the power cord is broken
or frayed, repair or replace immediately. Don’t
take chances with electrical fire or shock.
5.
Clean outside of all tanks and check for
damage.
MONTHLY MAINTENANCE
1. Check all bearings for noise and wear.
2. Check all gaskets for wear and leakage.
3. Check pump pressure; observe spray pattern
and check gauge if necessary.
4. Check overall performance of machine.
SEMI-ANNUALLY
1. Check vacuum motor brushes
.
LUBRICATION
For hose fitting lubrication, use a light silicone
lubricant which will not damage o-rings.
