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.
5.) Grease piston inside pressure regulator.
SEMI-ANNUALLY
1.) Check vacuum motor brushes.
LUBRICATION
For hose fitting lubrication, use a light silicone
lubricant which will not damage o-rings.
STORAGE
