MACHINE OPERATION
NINJA INTL 86038610 03/29/07
3-3
PRE-RUN INSPECTION
1. Check all fittings and connectors for proper
assembly.
2. Check all hoses for leaks. Repair or replace
any damaged hoses.
3. Check power cord(s) for any damage. If
damaged, replace.
EQUIPMENT SET-UP
1. Plug power cord from machine into properly
grounded wall outlet.
2. Turn vacuum motor switch on and off to
make sure there is electrical power at
machine.
3. Connect vac hose to machine. Slide the
swivel cuff over the outlet on the tank.
4. Connect the hose to your machine and
wand. Pull back the knurled collar on the
quick disconnect coupler and push onto the
connection on the chassis. To avoid leaks,
check to be that a positive connection was
made.
5. Using a clean container, fill the solution tank
with clean hot water. Mix in a non-foaming
cleaning concentrate for use in hot water
extraction machines, following the
manufacture’s instructions printed on
container.
NOTE: When using a powder cleaner, pre-mix
with hot water in a clean container before adding
to the solution tank.
6. Turn pump and vacuum switch(s) to the on
position.
7. Start cleaning.
PRIMING THE PUMP (SELF PRIMING VALVE)
[High Pressure Pump Models ONLY]
Turn pump and both vacuums on.
1. Press lever (located above the accessory
connection; front of machine) toward
machine.
2. Do this for 30 seconds or until there is a
steady flow of water flowing through the sight
tube. (located on right side of recovery tank.)
EMPTYING AND CLEANING
Always use
defoamer if foaming
occurs. Foam will
suspend large particles that may damage
vacuum(s) as well as allow liquid into the
vacuum motor(s) without activating the float
shutoff.
1. Before proceeding, make certain that the
nozzle is functioning properly.
a. To check, hold the wand about one foot
above the surface to be cleaned and
open the wand valve. A full spray should
be observed from the nozzle.
b. If the nozzle is not showing a full spray
pattern, adjust nozzle for proper pattern,
clean, or replace nozzle.
2. Normally, chemical is applied on the push
stroke of the wand when cleaning.
Vacuuming is done on the pull stroke. For
heavily soiled carpets the wand may be used
in a scrubbing manner, applying chemical in
both the push and pull stroke.
3. When cleaning, keep the working opening
(wand mouth) flat on the surface being
cleaned. Keep the wand moving when the
valve is open.
4. The shutoff float inside the vacuum tank will
impede the vacuum flow when the vacuum
tank is full.
When this occurs, empty the vacuum tank by
opening the dump valve and dispose of the
waste in a proper manner.
5. Once the vacuum tank has been emptied,
you may once again proceed with cleaning
