DAILY MAINTENANCE:
(At the end of each working day) :
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. Waste water should be
disposed of properly.
4) Remove lint build-up from the float shut-off
screen in the recovery tank . (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 lay on wet carpet. To
prevent electrical shock replace cords that
are frayed or have cracked insulation
immediately.
7) Ensure automatic shut-off ball is working
properly.
8) Clean all dirt and obstructions from drain
valve and gaskets to prevent possible
leakage and premature wear.
9) Run clean water through solution pump
when work is complete.
10) Empty both tanks and rinse, run vacuum(s)
for at least one minute to dry motor(s).
11) 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 of
water) or anti-browning solution (mixed as
directed) through the extractor, turning
pump switch on/off several times, flush with
clean water. This will prevent build-up of
alkaline residue in the system.
2) Check hoses for wear, blockages, or
damage. Frayed or cracked hoses should
be repaired or replaced to eliminate vacuum
or solution pressure loss.
3) Check all handles, switches, knobs,
electrical cables and connections on your
machine for damage. If the cable insulation
is broken or frayed, repair or replace it
immediately. Don’t take chances with
electrical fire or shock.
4) Clean out solution tank and remove and
clean solution screen.
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 with gauge if necessary.
4) Check overall performance of machine.
SEMI-ANNUALLY
1) Check vacuum motor brushes.
