NINJA INTL 86038610 03/29/07
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.
DO NOT attempt to
repair hose!
Repairing high-
pressure hoses may result in severe burns and
serious injury.
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.
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. 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 gauge if necessary.
4. Check overall performance of machine.
SEMI-ANNUALLY
1. Check vacuum motor brushes.
LUBRICATION
For pressure regulator and pump cam lubrication,
use a light silicone lubricant which will not damage
o-rings. A small tube (86246790 – PRV NO.
51391) is supplied with your machine.
STORAGE
Thoroughly clean machine if it is to be stored. You
