OPERATING PROCEDURES
WARNING! For the safe operation of this machine follow the instructions given in this booklet and the training given by
your supervisor. Failure to do so can result in personal injury and/or damage to machine and property!
DO NOT OPERATE MACHINE IN AN EXPLOSIVE ENVIRONMENT!
WARNING! NEVER USE THIS MACHINE TO PICK UP VOLATILE OR EXPLOSIVE MATERIAL!
The model shown in this manual is intended for commercial use.
PREPARATION
1. Check power cord, plug and strain relief for worn or damaged insulation. Repair or replace if necessary.
2. Confirm the drain valve is closed (T-handle pushed down). If the valve is left open, the vacuum performance is
dramatically reduced and any recovered solution will drain out.
3. The lever for the spool valve is located on the lower back panel of the machine near the left wheel. During normal
operation as a self contained extractor this lever is turned toward
“CARPET SPRAY”
(vertical position). It should be
turned to the
“ACCESSORY TOOLS”
position (horizontal) when a wand or other tool is being used.
4. Inspect the vacuum head and brush by tilting the machine backwards, allowing it to balance on the wheels and drain
spout.
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.
5. Check the inlet strainer for damage or debris. It is located at the bottom of the fresh water tank. Holes in the
screen can allow contaminants to enter the pump resulting in costly repairs. A clogged screen will reduce pump
performance and may cause permanent damage.
6. Remove the clear dome plate on top of the recovery tank.
a) Inspect for damage to the dome plate 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 foam filter and screen at the vacuum hose connection should be clean of debris and checked periodically
for any damage, replace if necessary.
c) Ensure that the intake filter is in its proper position to prevent recovered water from entering the vacuum motor.
Return the cover to its original position on the recovery tank and connect the hoses. The suction hose that runs from the
vacuum shoe to the dome connects to the right side and comes out of the rear of the machine on the right, lower side.
The hose that runs from the vacuum motor to the dome that creates the suction connects to the left side of the dome.
OPERATION
The following procedures are intended to describe and detail 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 (lower tank located at the front of the
machine). Follow mixing instructions for 8 gallons of water. Then fill the tank with warm to hot water. Do not use
water hotter than 600C (1400F). DO NOT OVERFILL.
3. Connect the power cord plug to a 115 volt grounded wall socket. See Grounding Instructions on page 2. 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.
4. Turn the spool valve knob (located at the back, left of the machine to the:
a) “Carpet Spray” (vertical) position for routine carpet extraction as a self contained unit, or:
b) Turn it in the “Accessory Tools” (horizontal) position when using a wand or tool.
5. The switch panel is located on top of the handle and contains the following:
a) Pump switch: Make sure in the intermittent (off) position for standard carpet extraction. The switch is only turned
to the continuous (On) position for either prespraying (for which you will tilt the machine backwards slightly and
run the machine back and forth over the area to be treated. All other switches should be in the Off position for
prespraying) or when using an hand tool or wand after the pump direction valve has been set to “Accessory Tools”
setting and the solution hose for th etool has been connected to the quick disconnect at the rear of the machine.
b) Turn the vacuum switch on to start the vacuum motor.
c) Turn the brush motor switch on to start the brush motor.
