SAVE THESE INSTRUCTIONS
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 equip-
ment 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 quali-
ed electrician or service person if you are in doubt as to weather the outlet is properly grounded.
Do not modify the plug provided with the appliance - if it will not t the outlet, have a proper outlet installed by a qualied electrician.
This appliance is for use on a nominal 120 - Volt circuit, and has a grounded plug that looks like the plug illustrated in sketch A be-
low. A temporary adapter that looks like the adapter illustrat-
ed in sketches B and C may be used to connect this plug to a
2-pole receptacle as shown in sketch B if a properly grounded
receptacle is not available. The temporary adapter should be
used only until a properly grounded outlet (sketch A) can be
installed by a qualied electrician. The green colored 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.

IMPORTANT:
This vacuum is equipped with a self-resetting thermo-protection switch to prevent overheating of the vacuum’s compo-
nents. If this switch activates and shuts down the motor during vacuuming, it is necessary to wait 15-20 minutes for the
motor to cool and for the thermo-protection switch to reset itself. Normally, the thermo-protection switch is activated
when airow is severely restricted from a full disposable bag. To avoid motor overheating, avoid excessive overlling
of the disposable bag. We recommend changing the disposable bag when it is 1/2 full. Replacing disposable bags
frequently will maximize your vacuums capabilities. It ensures greater airow, increased worker productivity and no
interruptions due to an overheated motor. Removing the disposable bag is fast and easy. Just reverse the steps on the
following page for installing the disposable bag. If the motor overheats after replacing the bag, check for an obstruction
in the vacuum hose or the hose inlet located on the tank.
WARNING:
Be certain the HEPA lter and disposable bag are installed correctly before using this vacuum. Failure to do so could
expose people in the work area to hazardous particles that could represent a serious health risk.
WARNING:
When using this vacuum to recover hazardous dust, do not attempt to open or dispose of its contents without personal
protection equipment (PPE). In addition, this procedure must be completed in a controlled & contained environment.

HEPA FILTER SYSTEM
HEPA Filter: Your vacuum is equipped with an individually tested and certied HEPA lter that is 99.97% ecient
at .3 microns or larger. The HEPA lter is located inside the plastic lid.
To remove:
Grasp the plastic lid with
one hand and pull away
one of the tabs that secure
the HEPA lter. Repeat
with other tabs until HEPA
lter is loose and can be
removed from the lid.
To replace:
Slide HEPA lter ange un-
der one tab, then press the
HEPA lter rmly so it locks
inside the plastic lid.
Other Attachments:
Motor Inlet Filter:
This lter should be in-
spected and/or replaced
if clogged with dust and
debris.
Excessive dust on the mo-
tor inlet lter will indicate a
lack of an air seal between
the motor and HEPA lter.
Center Filter Seal Gasket:
This important gasket cre-
ates an air seal between
the vacuum motor and
HEPA lter. Due to the
strength of the air seal,
the act of removing the lid
may cause the center lter
seal gasket to move from
its original position. If this
occurs, inspect the gasket
carefully. Remove any
visible dust or debris, then
carefully seat it securely
back on the base of the
motor column.
