Operation
WARNING
To reduce the risk of fire or explosion, do not operate this vac in areas with
flammable gases or flammable vapors such as lighter fluid, cleaners, oil-base
paints, gasoline, alcohol or explosive dust such as coal, magnesium, grain or
gun powder in the air. Do not vacuum explosive dust, flammable or combusti-
ble liquids or hot ashes. Do not use this vac as a sprayer. To reduce the risk of
health hazards from vapors or dusts, do not vacuum toxic materials. To
reduce the risk of electrical shock do not expose to rain. Store vac indoors.
Unplug power cord before changing or cleaning filter or emptying the dust
drum.
CAUTION: To reduce the risk of hear-
ing damage wear ear protectors
when using the vac or blower for
extended hours or when using it in a
noisy area. The operation of any util-
ity vac or blower can result in foreign
objects being blown into the eyes,
which can result in severe eye dam-
age. Always wear safety goggles
complying with ANSI Z87.1(or in Can-
ada CSA Z94.3-99) shown on Pack-
age before commencing operation.
Safety Goggles are available at many
local retail stores.
To reduce the risk of electric shock, this
appliance has a polarized plug (one blade
is wider than the other). This plug will fit in
a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the
plug. If it still does not fit, contact a quali-
fied electrician to install the proper outlet.
Do not change the plug in any way.
NOTE: When using the unit in the vacuum-
ing mode, always insert the air diffuser in
the exhaust port on the detachable blower.
This breaks up the direct flow of air and dif-
fuses it.
Familiarize yourself with the accessories
included with the vac. Each accessory may
be used in various ways for vacuuming and
blowing debris. Here is a list of the accesso-
ries and their uses.
Utility Nozzle - General purpose nozzle for
most vacuuming applications.
Wet Nozzle -Usedforwetpickupon
smooth surfaces to pick up liquid and dry
the surface in one stroke.
Car Nozzle - Dry pickup nozzle for car inte-
riors and most upholstery cleaning.

Blower Nozzle - Attached to the end of a
hose or directly to the power assembly con-
centrates the air for blowing applications.
Diffuser - Insert in the exhaust of the vac
while vacuuming and the air exiting the
exhaust is “diffused”. This breaks up the air
coming out of the exhaust.
Extension Wands - These wands can be
connected together and provides additional
length for more reach.
Hose - Provides transfer of vacuum or blow-
ing capability to work site. Provides the
means of attaching extension wands and
nozzles.
Male To Male Adapter - Usethisaccessory
to connect the blower nozzle to the exhaust
of the power assembly.
Accessory Caddy - Store all the accesso-
ries with your vac.
Caster Feet (Front) - Store accessories
with your vac.
Vacuuming Dry Materials
1.The filter must be in correct position at
all times to avoid leaks and possible
damage to vac.
2.When using your vac to pick up very
fine dust, it will be necessary for you to
empty the drum and clean the filter at
more frequent intervals to maintain vac
performance.
NOTE: A dry filter is necessary to pick up
dry material. If you use your vac to pick up
material when the filter is wet, the filter will
clog quickly and be very difficult to clean.
3.If your filter is wet but you need to use
the vac to pick up dry material, you can
quickly dry the filter by running the vac
without hose attached for about 10 min-
utes. The clean air rushing through the
vac will help dry the filter.
Vacuuming Liquids
1.When picking up small amounts of liq-
uid the filter may be left in place.
2.When picking up large amounts of liq-
uid we recommend that the filter be
removed. If the filter is not removed, it
will become saturated and misting may
appear in the exhaust.
CAUTION: Do not remove the filter
cage or float. It is there to shut off air-
flow when the drum is full of liquids.
3.When the liquid in the drum reaches a
predetermined level, the float mecha-
nism will rise automatically to cut off air-
flow. You will know that the float has
risen because vac airflow ceases and
the motor noise will become higher in
pitch, due to increased motor speed.
When this happens, turn off the vac,
unplug the power cord, and empty the
drum.
4.After using the vac to pick up liquids,
the filter must be dried to avoid possible
mildew and damage to the filter.
IMPORTANT: To avoid damage to the vac
do not run motor with float in raised position.
Emptying Dust Drum
WARNING: To reduce the risk of
injury from accidental starting,
unplug power cord before emptying
the drum.
1.To remove the lid to empty contents of
the dust drum, simply lift the two drum
latches at the front and rear of the dust
drum and lift the lid assembly up and off
the dust drum and set to the side.
2.Lay the lid assembly upside down on a
clean dry area while emptying the drum
or changing the filter.
3.Dump the drum contents into the proper
waste disposal container.

10
Operation (continued)
4.If the contents are liquid, you may dis-
pose by using the drain provided in the
drum for easy emptying. Simply unscrew
the drain cap and allowthe liquidto drain
completely out of the vac drum.
WARNING: To reduce the risk of back
injury or falls, do not lift a vac heavy
with liquid or debris. Scoop or drain
enough contents out to make the vac
light enough to lift comfortably.
Cord Wrap
When vacuuming is complete, unplug the
cord and wrap it around thepower assembly
as shown. The cord should wrap under the
pullhandle (above the inlet) and around and
under the handle to the power assembly.
Moving the Vac
Should it become necessary to pick the vac
up to move it, the handles on the sides of
the dust drum are used to lift. To maneuver
the vac, the pull handle above the inlet
should be used.
Blowing Feature
Your wet/dry vac has a “detachable blower”.
It has the capability to be used as a dedi-
cated blower for yard work, patio cleanup
and workshop applications to blow sawdust
and other debris.
WARNING: Always wear safety gog-
gles complying with ANSI Z87.1 (or
in Canada CSA Z94-3-M88)before
using as a blower.
WARNING: Wear a dust mask if blow-
ing creates dust which might be
inhaled.
CAUTION: To reduce the risk of hear-
ing damage wear ear protectors
when using the vac/blower for
extended hours or when using it in a
noisy area.
WARNING: To reduce the risk of
injury to bystanders, keep them clear
of blowing debris.
1.Familiarize yourself with the detachable
blower portion of your wet/dry vac.
2.Remove the detachable blower of your
vac by pressing down on the power
head latch under the handle of the
detachable blower. (This power head
latch holds the detachable blower to the
lid assembly.)

Cleaning Vac Filter
Your filter should be cleaned often to main-
tain peak vac performance.
Be sure to dry the filter before storing or
picking up dry debris.
IMPORTANT: After cleaning, check the fil-
ter for tears or small holes. Do not use a fil-
ter with holes or tears in it. Even a small
hole can cause a lot of dust to come out of
your vac. Replace it immediately.
NOTE: The filter is made of high quality
paper designed to stop very small particles
of dust. The filter can be used for wet or dry
pick up. Handle the filter carefully when
removing to clean or installing it. Creases in
the filter pleats may occur from installation
but will not affect the performance of the fil-
ter.
Removal
To remove the filter for cleaning or replace-
ment, unscrew the filter nut from the filter
cage, remove filter plate and lift off filter.
IMPORTANT: To avoid damage to the
blowerwheel and motor, always reinstall the
filter before using the vac for dry material
pickup.
CAUTION: Do not remove the filter
cage or float. It is there to shut off air-
flow when the drum is full of liquids.
Dry Filter
1.Light cleaning of some dry debris can
be accomplished without removing the
filter from the vac. Simply slap your
hand on top of the lid while the vac is
turned off.
2.Clean the filter in an open area. Clean-
ing SHOULD be done outdoors and not
in the living quarters.
3.Remove filter from vac. Gently tap the fil-
ter against the inside wall of your dust
drum and the debris will loosen and fall.
4. For thorough cleaning of dry filter with fine
dust (no debris) you may run water
through it as described under “Wet Filter”.
Wet Filter
Remove filter from vac, run water through
the filter from a hose or spigot. Take care
that water pressure from the hose is not
strong enough to damage filter. Remember:
To dry a filter quickly, reinstall the filter on
the vac and allow the unit to run for 10 min-
utes. The clean air rushing through the filter
will dry it.
Installation
Refer to “Filter Assembly”.
Allow the filter to dry before reinstalling and
storing the vac.

NOTE: To quiet noisy casters put a drop of
oil on the roller shaft.

13
Wet Nozzle
To pick up liquids off a smooth surface, use
the 2-1/2" wet nozzle accessory supplied
with your wet/dry vac. To use, simply attach
the nozzle to the end of an extension wand.
Connect a second extension wand to the
first, and connect the 2-1/2" x 7' hose to the
extension wand.
Liquids may be picked up by dragging the
nozzle across the surface. The squeegee
will dry the surface as you vacuum.
If the rubber becomes worn, it may be
flipped over for use on the opposite side or
replaced. (Replacement service part
#822256). To reverse or replace the squee-
gee:
1.Lay the wet nozzle on a flat surface with
the round inlet opening facing up and
the two latches close to you as shown.
2.Using both hands, position each thumb
on the removable insert, (below the
latches) and two fingers of each hand
on each latch, lift and disengage the
two latches from the tabs on the nozzle
body.
3.Gently pull the latches toward yourself
to remove the insert.
To reinstall the removable insert correctly,
follow these steps:
1.Place the removable insert on a flat sur-
face with the pins positioned upward
and the latches close to you as shown.
Place the rubber squeegee on the
insert, with the pins fitting through the
matching holes in the squeegee. (Make
sure the new working edge is located
farthest from you.)
2.Using both hands, lower the nozzle
body onto the insert and squeegee with
the round opening of the nozzle closest
to you. With fingers on the far side and
thumbs holding the latches of the

GUARDEESTASINSTRUCCIONES
El funcionamiento de cualquier aspiradora o soplador
de uso general puede dar como resultado que salgan
proyectados objetos extraños hacia los ojos, lo cual
puede causar daños graves en los ojos. Use siempre
anteojos de seguridad (no use gafas) que cumplan
con la norma ANSI Z87.1 (o en Canadá, con la norma
CSA Z94.3-99) mostrados en el paquete. Las gafas
corrientes sólo tienen lentes resistentes a los golpes.
No son gafas de seguridad. Los anteojos de seguri-
dad se encuentran disponibles en muchas tiendas
minoristas locales. Las gafas o los anteojos que no
cumplan con la norma ANSI o CSA podrían causarle
lesiones graves al romperse.
Para reducir el riesgo de daños a la audición, use
protectores de oídos cuando utilice la aspiradora
durante muchas horas seguidas o cuando la emplee
en un área ruidosa.

eléctricas. Cuando utilice un cordón de extensión, ase-
gúrese de que estéen buenas condiciones. La utiliza-
