INSPECTION
Carefully unpack and inspect your machine for shipping damage. Each unit is tested and thoroughly
inspected before shipment, and any damage is the responsibility of the delivery carrier who should
be notified immediately.
ELECTRICAL
This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit. V oltages
below 105 volts AC or above 125 volts AC could cause serious damage to the motor.
-
115 Volt
WARNING
Electric motors can cause explosions when operated near explosive materials or vapors. Do not
operate this machine near flammable materials such as solvents, thinners, fuels, grain dust, etc.
GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce the risk of electric shock. This appliance is
equipped with a cord having an equipment-grounding conductor and grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
DANGER
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 appliance — 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 grounding plug that looks like the
plug illustrated in Sketch A. Make sure that the machine is connected to an outlet having the
same configuration as the plug. No adapter should be used with this appliance.

WARNING
This vacuum may contain potentially hazardous dust depending on its appilcation. Special handling
of contaminated disposal bags and filters is recommended. Disposal must be in compliance with
local EPA regulations
USER MAINTENANCE INSTRUCTIONS
All service and repair should be performed by qualified vacuum service representative or electrician.
No user serviceable components are employed in the electrical vacuum lid head assembly. No
lubrication of the motor is required.
CLOTH BAG & HOSE ASSEMBLY
Cloth bag and hose assembly are user maintenance items and can be replaced when worn out.
For optimum performance, empty and clean filter bag regularly. A clogged and dirty bag restricts
the flow of air and results in reduced vacuum. The hose assembly can be maintained by wiping
off with a dampened cloth of mild liquid soap and water, then allowed to dry.
CORD STORAGE
While not in use storage can be accomplished by winding cord around motor lid assembly. Cord
should be completely unwound from lid assembly during operation.
• Do not use with damaged cord or plug. If appliance is not working as it should, has been
dropped, damaged, left outdoors, or dropped into water, return to service center.
• Do not pull or carry by cord, use cord as handle, close a door on cord, or pull cord around sharp
edges or corners. Do not run appliance over cord. Keep cord away from heated surfaces.
• Do not unplug by pulling cord. To unplug, grasp the plug, not the cord.
• Do not handle plug or appliance with wet hands.
• Always unplug the machine when removing the motor head off the tank. This equipment should
be stored indoors and not exposed to rain.

Each facility has its own individual and unique cleaning problems, it is suggested that you use the following:
Tank/Filter Set-Up Procedure
1. Fully open the plastic bag and place it down into the tank on the underside of the intake tube as shown.
2. Take the paper bag that has the cardboard collar attached and open it up by gently pulling the folds apart.
3. You will notice two creases on the top side of the collar; carefully bend the ends down (toward) the bag.
4. Insert this bag into the tank and push it to the bottom, taking care not to snag the plastic bag.
5. Locate the cardboard collar around the intake tube and gently work it up past the raised ring that runs around
6. Push the plastic bag down past the paper bag; position it about 1/2 to 2/3 down past the top of the bag.
7. Starting at the bottom of the cloth filter, slip the paper filter protector over the entire cloth filter until the elastic

not to rip the paper filter protector when pushing the cloth filter with steel frame into the tank.
U.L.P.A. filter will go down inside the cloth filter. Make sure that the motor lid is seated onto the ring of the cloth
filter frame completely around the tank.
For proper cleaning of the tank and removal/changing of the filters, see “Procedures in Removing Contaminated
Filters and Cleaning of Contaminated Tank.”
Procedures in Removing Contaminated Filters
and Cleaning of Contaminated Tank
Always wear a facemask and gloves when conducting this procedure.
1. Unplug the machine from the power source.
2. Carefully and slowly unlatch the tank latches and remove the vacuum lid only (be sure when you lift up on the
lid that the cloth filter stays inside the tank.) Set the lid with the U.L.P.A. filter assembly aside.
3. Gently remove the cloth and paper filter protector from the tank. Carefully place the paper and cloth filter into a
plastic bag. With one hand grab the bottom of the paper filter protector through the plastic bag and with the
other hand release the elastic band from around the cloth filter frame. Slide the cloth filter out of the paper bag.
Set the cloth filter and frame aside.
4. Before closing up the plastic bag with the used paper filter inside, check the prefilter filter attached to the
U.L.P.A. filter for any noticeable dirt. The impact filter should be changed every other time you change the
paper filter or if any dirt particles are noticed during inspection. Then the used impact filter can also be put into
the plastic bag before sealing up for disposal. See “Changing the Black Foam Prefilter” for more information.

Changing the Black Foam Prefilter
The prefilter should be changed using all of the precautions previously mentioned.
The prefilter should be changed when any of the following takes place:
1. Anytime there is an indication of a filter tear during normal operation of the unit. This tear could be in any of the
filters used.
a. paper dust containment bag
b. paper bag protector
c. cloth filter bag
These tears would show up during the tank clean-out procedure, or...
2. Every other tank clean-out period. To change the prefilter, do the following before you do Step #3 of the normal
clean-out procedure.
a. Wipe down all of the exposed surfaces on the underside of the removed lid, using the dampened wiping
cloth.
b. Remove the prefilter from the high efficiency filter. Be careful so as not to damage or puncture the U.L.P.A.
media used in the final filter . Do not attempt to clean the prefilter in any way; dispose of by placing it into the
tank you are now in the process of cleaning. DO NOT USE ANY TOOLS TO REMOVE THE PREFILTER.

Changing of Pre-Filters
In order to prolong the efficiency and performance of the critical filter it is recommended that
each pre-filter, debris bag and paper filter protector be changed every time the debris bag is
full. Change the impact filter every second time or if a bag breaks or tears. Follow the manual
for bag replacement.
Whenever the vacuum is in operation or being emptied, the operator should be wearing
protective clothing and respirator for protection.
All used pre-filters and debris bags should be handled and disposed of in accordance with local
regulations.
