Vacuuming Liquids

IMPORTANT:
1. When picking up small amounts of liquid
the filter may be left in place.
2. When picking up large amounts of liquid
we recommend that the filter be
removed. If the filter is not removed, it
will become saturated and misting may
appear in the exhaust.
3. After using the vac to pick up liquids, the
filter must be dried to reduce the risk of
possible mildew and damage to the filter.
4. When the liquid in the drum reaches a
predetermined level, the float mechanism
will rise automatically to cut off air-flow.
When this happens, turn off the vac,
unplug the power cord, and empty the
drum. 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.
IMPORTANT: To reduce the risk of
damage to the vac do not run motor with
float in raised position.

Filter Performance Sensor

1. This Wet/Dry Vac features an innovative
device for determining when your filter
needs to be cleaned. This patent
pending design works whether the
Wet/Dry Vac is on or off.
2. Bars of color show the cleanliness of
your filter. All green bars indicate that
your filter is clean and ready to use.
3. As the filter becomes dirty, orange bars
will appear and green bars will
disappear.
4. All orange bars indicate that your filter is
dirty and needs to be cleaned or
replaced.
5. Your Wet/Dry Vac operates most
efficiently and powerfully, with a clean
filter. When the filter performance
sensor shows all orange bars, the
performance of your Wet/Dry Vac is
approximately 40-55% of its original
power with a clean filter. At any point
during the increasing orange bars,
you may elect to clean the filter.

6. To set the indicator bars back to the
original full green position, press the
sensor reset button.
NOTE: Do not press the sensor reset button
while the Wet/Dry Vac is running. This may
damage the filter performance sensor.
7. Press the sensor reset button until all
green bars show. This should be done
whenever you clean or replace the filter.
Depending on how clean you get the
filter, will determine how many orange
bars show. A new filter will show all
green.

Emptying the Drum

for easy emptying of liquids. Simply
unscrew the drain cap and lift the
opposite side slightly to empty the drum.

Moving the Wet/Dry Vac

Should it become necessary to pick the
vac up to move it, the handle on the sides
of the dust drum are used to lift. To
