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-M88) 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 vacu-
uming mode, always insert the air diffuser
in the exhaust port on the detachable
blower. This breaks up the direct flow of
air and diffuses it.
Familiarize yourself with the accessories
included with the vac. Each accessory
may be used in various ways for vacuum-
ing and blowing debris. Here is a list of the
accessories and their uses.
Utility Nozzle - General purpose nozzle
for most vacuuming applications.
Wet Nozzle - Used for wet pickup on
smooth surfaces to pick up liquid and dry
the surface in one stroke.
Car Nozzle - Dry pickup nozzle for car
interiors and most upholstery cleaning.
Blower Nozzle - Attached to the end of a
hose or directly to the power assembly
concentrates the air for blowing applica-
tions.
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 addi-
tional length for more reach.
Hose - Provides transfer of vacuum or
blowing capability to work site. Provides
the means of attaching extension wands
and nozzles.
Male To Male Adapter - Use this acces-
sory to connect the blower nozzle to the
exhaust of the power assembly.
Accessory Caddy - Store all the acces-
sories 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.

11
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.
NOTE: Do not pick up the lid assembly by
lifting on the handle to the detachable
blower. Lift the lid assembly by the
latches. This will ensure that the detach-
able blower and the lid will not separate
during removal of the lid assembly.
2.Lay the lid assembly upside down on a
clean dry areawhile emptying thedrum
or changing the filter.
3.Dump the drum contents into the proper
waste disposal container.
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 allow the liq-
uid to 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 comfort-
ably.

Operation (continued)
Cord Wrap
When vacuuming is complete, unplug the
cord and wrap it around the power assem-
bly as shown. The cord should wrap
under the pull handle (abovethe 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 dedicated 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

Cleaning Vac Filter
Your filter should be cleaned often to
maintain peak vac performance.
Be sure to dry the filter before storing or
picking up dry debris.
IMPORTANT: After cleaning, check the
filter for tears or small holes. Do not use a
filter 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 parti-
cles 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 perfor-
mance of the filter.
Removal
To remove the filter for cleaning or
replacement, remove filter nut from the
screw on the filter cage, and lift off filter.
IMPORTANT: To avoid damage to the
blower wheel and motor, always reinstall
the filter before using the vac for dry mate-
rial 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. Remem-
ber: To dry a filter quickly, reinstall the fil-
ter on the vac and allow the unit to run for
10 minutes. 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.
Wet/Dry Vac
To keep your Wet/DryVac looking its best,
clean the outside with a cloth dampened
with warm water and mild soap.
To clean the drum:
1.Dump out debris.
2.Wash drum thoroughly.
3.Wipe out with dry cloth.
WARNING: To assure product
SAFETY and RELIABILITY, repairs
andadjustment should beperformed

of oil on the roller shaft.

15
Wet Nozzle
To pick up liquids off a smooth surface,
use the 2-1/2" wet nozzle accessory sup-
plied with your wet/dry vac. To use,simply
attach the nozzle to the end of an exten-
sion 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
squeegee:
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
removable insert, flip the nozzle over so
the latches are on the top and the round
inlet opening is facing away from you.
Make sure the squeegee stays on the
insert pins.
3.Press down with each thumb below the
latching tabs until you see and hear the
removable insert snap into the nozzle
body. Snap the latches over the locking
tabs into their original position.
4.Inspect the pins of the insert to make
sure they fit through the holes of the
squeegee and fit into the matching slots
in the nozzle body.

WARNING
SERVICING OF DOUBLE-INSULATED WET/DRY VAC
In a double-insulated Wet/Dry Vac, two systems of insulation are provided
instead of grounding. No grounding means is provided on a double-insulated
appliance, nor should a means for grounding be added. Servicing a double-
insulated Wet/Dry Vac requires extreme care and knowledge of the system,
and should be done only by qualified service personnel. Replacement parts
for a double-insulated Wet/Dry Vac must be identical to the parts they replace.
Your double-insulated Wet/Dry Vac is marked with the words “DOUBLE INSU-
LATED” and the symbol (square within a square) may also be marked on
the appliance.
* Standard Hardware Item - May be purchased locally
† These replacement parts are available where you purchased your vac.
