IMPORTANT SAFETY INSTRUCTIONS
READ AND UNDERSTAND ALL WARNINGS AND INSTRUCTIONS
BEFORE USING THIS MACHINE!
WARNING! To reduce the risk of fire, electric shock, or injury:
1. You must be trained to operate this machine. This machine is to be operated for its intended use
only.
2. Do not operate this machine unless it is completely assembled.
3. Always use a three-wire electrical system connected to the electrical ground. For maximum protection against electrical shock, use a circuit that is protected by a ground fault circuit interrupter. Consult your electrical contractor.
4. To prevent electrical shock: Always remove the electrical plug from the electrical outlet before performing any repairs, maintenance or cleanup and when leaving the machine unattended.
5. To prevent electrical shock: Keep the machine surface dry; Do not subject to rain; Store the machine
in a dry building area; Clean the machine with a dry cloth only.
6. Machines can cause an explosion when near flammable materials and vapors. Do not use or store
this machine with or near fuels, grain dust, solvents, thinners, or other flammable materials. Do not
use flammables to clean this machine.
7. Maintenance and repairs must be done by a qualified or authorized person.
8. If the machine is not working as it should, has been dropped, damaged, left outdoors, or dropped into
water, return it to a service center.
9. To avoid damage to the machine’s electrical cord, always lift the machine over the cord. Do not run
the machine over the electircal cord.
10. Make sure all labels, decals, warnings, cautions and instructions are fastened to the machine.
Grounding Instructions
This machine must be grounded. If it should malfunction or break down,
grounding provides a path of least resistance for electric current to reduce the
risk of electric shock. This machine is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be inserted
into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
WARNING - Improper connection of the equipment-grounding conductor
can result in a risk of electric shock. Check with a qualified electrician or
service person if you are in doubt as to whether the outlet is properly grounded.
Do not modify the plug provided with the machine - if it will not fit the outlet,
have a proper outlet installed by a qualified electrician.
This machine is for use on a nominal 120-volt circuit, and has a grounded
plug that looks like the plug illustrated in figure A. A temporary adapter that
looks like the adapter illustrated in figures B and C may be used to connect
this plug to a 2-pole receptacle as shown in figure B if a properly grounded
outlet is not available. The temporary adapter should be used only until a
properly grounded outlet (figure A) can be installed by a qualified electrician. The green colored rigid ear, lug, or the like extending from the adapter
must be connected to a permanent ground such as a properly grounded outlet
box cover. Whenever the adapter is used, it must be held in place by a metal
screw.
NOTE: In Canada, the use of a temporary adapter is not permitted by the
Canadian Electrical Code
EXTENSION CORDS
Use only three-wire 16/3 or larger gauge approved extension cords that have
three-prong grounding type plugs and three-pole receptacles that accept the
appliance’s plug. Replace or repair any damaged cords or plugs.
When servicing, refer to authorized person only. Use only identical replacement parts.
NOTE: Do not use adapters shown in figures B & C in Canada

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 MATERIALS.
OPERATION
To prepare the machine for operation, make sure it is of the
correct voltage and properly assembled. If in doubt, ask
your supervisor.
FOR DRY PICK-UP:
“Dry” refers to material such as dust, dirt, debris and dry
foam shampoo.
1. Release the clamp on the side of the tank and head
assembly. Lift the head assembly off and set it aside.
2. Then lift the cloth filter assembly out of the collector
tank. Clean the cloth filter if needed (reference the
“Maintenance” section).
3. Empty the collector tank of all dust and debris. If the
debris is wet, empty and dry the inside of the tank thoroughly.
FOR WET PICK-UP:
“Wet” refers to liquids such as water, scrub solutions and
detergents; NOT volatile or explosive materials.
1. Release the clamp on the side of the tank and head
assembly. Lift the head assembly off and set it aside.
2. Then lift the cloth filter assembly out of the collector
tank. Store the filter assembly for future, dry pick-up
use. DO NOT REINSTALL.
3. Empty the collector tank of all dust and debris. Also
wipe the inside of the collector tank to remove cling
ing dust.
4. Check the float shut-off device on the lower portion of
the head assembly. The float should have free movement. When the recovered liquid soilage reaches the
collector tank capacity, the float will rise to shut off
the air flow, stopping the liquid recovery. This prevents damaging overflow and signals the operator when
to empty the collector tank.
5. Replace the head assembly and fasten the clamp. Attach the hose, wand and floor tool of choice (reference
page 5).
6. Plug the power cord into a 115-volt, 60 cycle grounded
outlet.
7. Turn the machine’s motor on by pressing the rocker
switch which is located on the head assembly.
4. Place the cloth filter assembly back into the collector
tank. Check for a good seal around the outer filter lip
and tank rim.
5. Replace the head assembly and fasten the clamp. Attach the hose, wand and floor tool of choice (reference
page 5).
6. Plug the power cord into a 115-volt, 60 cycle grounded
outlet.
7. Turn the machine’s motor on by pressing the rocker
switch which is located on the head assembly.

MAINTENANCE
Good maintenance procedures assure better operation,
fewer repairs and longer life to your machine.
DISCONNECT THE ELECTRICAL PLUG OF THE
MACHINE FROM THE ELECTRICAL OUTLET
BEFORE DOING ANY CLEANUP, REPAIRS OR
MAINTENANCE OF THE MACHINE AND WHEN
LEAVING THE MACHINE UNATTENDED.
CLEAN THE MACHINE AFTER EACH USE:
1. Wipe the outside with a clean cloth.
2. Clean the collector tank: Release the clamps on each
side of the tank and head assembly. Lift the head assembly off and set aside. Lift the filter assembly out
of the collector tank and set aside. Then wipe the
inside of the collector tank with a clean cloth.
3. Empty and check the filter assembly: Empty the
recovered soilage into a suitable container and shake
to remove clinging dirt. Brush the outside of the filter
bag to remove embedded dirt. Check the filter assembly for tears or holes; repair or replace if necessary.
Install the clean filter assembly into the clean collector tank.
ELECTRICAL CABLE:
Check the cord for any nicks, cuts or damage. Report
these to your supervisor for correction.
VACUUM HEAD ASSEMBLY:
1. Gaskets: Clean the vacuum head gasket (23) and the
float shut-off gasket (24 on page 6).
2. Float Shut-Off Device: This should move freely. Remove
any debris or strings from the float cage.
3. Head Assembly: Replace and leave ajar if the collector tank is damp to prevent mildew.
WHEELS AND CASTERS:
Check these for cuts and nicks. Remove any strings or
debris that may restrict the free movement of the wheels.
Wipe the treads clean.
CARBON BRUSH INSPECTION:
Check for wear at six month intervals or every 600 hours
of operation. The carbon brushes must be replaced if worn
shorter than 3/8 inch.
