OPERATING PROCEDURES
WARNING! For the safe operation of this machine
follow the instructions given in this booklet and the train-
ing given by your supervisor. Failure to do so can result
in personal injury and/or damage to machine and prop-
erty!
DO NOT OPERATE MACHINE IN AN EXPLOSIVE
ENVIRONMENT!
NEVER USE THIS MACHINE TO PICK UP VOLA-
TILE OR EXPLOSIVE MATERIALS!
The model shown in this manual is intended for commer-
cial use.
PREPARATION
1.
Check
power cord
,
plug
and
strain relief
for worn or
damaged insulation. Repair or replace if necessary.
2.
Confirm the
quick connects
located at the back of the
machine are properly attached. This is the water supply
line and solution water will not be allowed to flow
through to the jets if this connection isn’t secure.
3.
Lock the
brush assembly
in the up position for storage
or transport. This is done by pulling up on the
black
knob/lift mechanism
at the front of the machine and
allowing the lift stop to rest on the bracket.
4.
Inspect the
vacuum head
and
brush
by tilting the ma-
chine backwards.
a)
Vacuum Head:
Check for any damage. Burrs on
the contact surface may snag carpet fibers. Gouges,
scratches and chipped areas can reduce vacuum
performance.
b)
Brush:
Inspect for damaged or missing bristles,
replace if necessary.
Return the machine to the upright position.
OPERATION
The following procedures are intended to describe and de-
tail proper operation of your machine. Failure to follow
these recommended procedures can reduce the machine’s
performance and may result in damage to the machine.
1.
Vacuum
the area to be cleaned
. Your machine will do
a more thorough job if the loose dirt and debris are
removed before the extraction process begins.
2.
Add NON-FOAMING cleaning concentrate to the
fresh
water/solution tank.
Follow mixing instructions for 3 to
3-1/2 gallons of water.
Then fill the tank with warm
water using the faucet/power fill adaptor
. Do not use
water hotter than 60
°
C (140
°
F).
Or, you may mix the concentrate with 3 to 3-1/2 gallons
of clean water in a CLEAN bucket, then pour the mixture
into the solution tank.
DO NOT OVERFILL.
NEVER USE THE RECOVERY TANK’S DIRTY
WATER TO FILL THE SOLUTION TANK!
3.
Ensure the water supply hose connection at the rear of
the machine is secure.
4.
Connect the power cord plug to a
115 volt
grounded
wall socket
. See Grounding Instructions. Use of an
extension cord is not recommended. However, if one is
necessary, use only a
14 gauge
or larger cord. Smaller
or inferior cords are dangerous and may cause damage
to your machine.
5.
Lower the brush assembly
by lifting theblack knob off
the storage/transport bracket.
6.
Turn on the
vacuum switch at the control panel
to start
the vacuum motor.
Note: The accessory pump switch is for use only with the
accessory tools. See “OPERATING WITH ACCESSORY
TOOLS”.
7.
Pull
backward during operation
. DO NOT AT-
TEMPT TO OPERATE IN A FORWARD DIREC-
TION.
Position yourself behind the machine, grasp
the handle and depress the red momentary “Pump/
Brush” switch on the top center of the handle
. This
switch activates the brush drive motor and the pump to
spray cleaning solution. Walk slowly backward and
continue to depress the red switch to perform the clean-
ing process.
5.
Check the
inlet screen and filter bag
in the opening of
the fresh water/solution tank for damage or debris. Holes
in the screen can allow contaminants to enter the pump
resulting in costly repairs. A clogged screen will re-
duce pump performance and may cause permanent dam-
age.
6.
Remove the clear dome on top of the recovery tank.
a)
Inspect for damage to the
dome
and
gasket
. Dirt
or debris on the gasket or sealing surface of the
tank can cause a vacuum leak and reduce vacuum
performance.
b)
The
intake filter screen
should be clean of debris
and checked periodically for any damage, replace
if necessary.
Return the cover to its original position.
