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. Your 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: 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.

Vacuuming Liquids

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. When the liquid in the drum reaches a
predetermined level, the float
mechanism 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.

Emptying the Drum

! WARNING: To reduce the risk of
injury from accidental starting,
unplug power cord before emptying
the drum.
1. The 12 gallon Vac comes equipped
with a drain for easy emptying of
liquids. Simply unscrew the drain cap
and lift the opposite side slightly to
empty the drum.
2. Pull the flexible latches outward on
each side of the lid to release from the
drum.
3. While holding the latches out, lift the
top assembly up and away from the
drum.
4. Lay top assembly upside down on a
clean area while emptying drum or
changing filter.
5. Dump the drum contents into the
proper waste disposal container.
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.

Moving the Wet/Dry 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.
The pull handle on the motor cover
should be used to maneuver the Vac.
