WARNING: To reduce the risk of fire, explosion, or damage to Vac:
• Do not leave Vac running while unattended - you may fail to notice important
signs indicating abnormal operation such as loss of suction, debris/liquid
exiting the exhaust, or abnormal motor noises. Immediately stop using Vac
if you notice these signs.
• Do not continue running when float has cut off suction.
• Sparks inside the motor can ignite airborne flammables. Do not operate Vac
near flammable liquids or in areas with flammable gases, vapors, or
explosive/airborne dust. Flammable liquids, gases, and vapors include:
lighter fluid, solvent-type cleaners, oil-based paints, gasoline, alcohol, and
aerosol sprays. Explosive dusts include: coal, magnesium, aluminum,
grain, and gun powder.
• Do not vacuum up explosive dusts, flammable liquids, or hot ashes.

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 accessories and their uses.
Multi-Purpose Tool - Dry pickup nozzle
for car interiors and most upholstery
cleaning.
Hose - Provides transfer of vacuum or
blowing capability to work site. Provides
the means of attaching the multi-purpose
tool.

Operation (continued)
Vacuuming Dry Materials
1. The filter must always 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
peak Vac performance.
NOTE: The paper filter must be dry in
order to pick up dry material. If you use
your Vac to pick up dust when the filter is
wet, the filter will clog quickly and be very
difficult to clean.
Vacuuming Liquids
1. When picking up small amounts of
liquid (up to one inch in the bottom of
the drum) the filter may be left in
place.
2. When picking up large amounts of
liquid (more than one inch in the
bottom of the drum) we recommend
that the filter be removed. If the filter is
not removed, it will become saturated
and misting may appear in the
exhaust.
WARNING: Do not remove the
filter cage and float. The float
prevents water from entering the
impeller and damaging the motor.
The cage prevents fingers from
touching the moving impeller.
!
3. When the liquid in the drum reaches a
predetermined level, the float
mechanism will rise automatically to
cut off airflow. 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, remove the
battery 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.
9
2. Lay the power head on a clean dry
area while emptying the drum or
changing the filter.
3. Dump the drum contents into the
proper waste disposal container.
Operation (continued)
Emptying the Drum
1. To remove the lid , grasp the drum
latches on both the right and left side
of the power head. Slowly pull the
drum latches out and up from the
drum. Lift the power head off the
drum. Place the lid assembly to the
side.
WARNING: To reduce the risk of
injury from accidental starting,
remove battery before emptying the
drum.
!
Blowing Feature
Your Wet/Dry Vac has the capability to
blow sawdust and other debris and to be
used as a blower for yard work, patio
cleanup and workshop applications.
NOTE: The blowing port is located
opposite the vacuum port.
WARNING: Always wear safety
eyewear complying with ANSI Z87.1
(or in Canada, CSA Z94.3) before
using as a Blower.
CAUTION: Wear a dust mask if
blowing creates dust which might
be inhaled.
CAUTION: To reduce the risk of
hearing damage, wear ear protectors
when using the Vac/Blower for
extended time or in a noisy area.
WARNING: To reduce the risk of
injury to bystanders, keep them
clear of blowing debris.

!
Filter
NOTE: The filter is made of high quality
paper designed to stop very small
particles of dust. The filter can be used
for dry pick up or small amounts of liquid.
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
filter.
IMPORTANT: To avoid damage to the

the filter before using the Vac for dry
material pickup.
12
Maintenance (continued)
WARNING: To reduce the risk of
injury from accidental starting,
remove battery before changing
filter.
!
Cleaning and Disinfecting the
Wet/Dry Vac
To keep your Wet/Dry Vac looking its
best, clean the outside with a cloth
dampened with warm water and mild
soap.
To clean the drum:
1. Dump debris out.
2. Wash drum thoroughly with warm
water and mild soap.
3. Wipe out with dry cloth.
Before prolonged storage or as needed
(i.e., waste water pick up) the drum
should be disinfected.
Cleaning A Dry Filter
NOTE: For best cleaning results due to
accumulated dust, clean the filter in an
open area. Cleaning SHOULD be done
outdoors and not in the living quarters.
1. Light cleaning of some dry debris from
the filter can be accomplished without
removing the filter from the vac.
Simply slap your hand on top of the
handle while the vac is turned off.
2. Remove filter from vac. Gently tap the
filter against the inside wall of your
dust drum and the debris will loosen
and fall.
3. For thorough cleaning of a dry filter
with fine dust (no debris) you may run
water through it as described under
“Cleaning A Wet Filter” Section.
Cleaning A Wet Filter
After filter is removed, 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.
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. If your filter is damaged or
worn, replace it immediately.
Allow the filter to dry before reinstalling
and storing the Vac or picking up dry
debris.
