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:
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.
IMPORTANT:
To reduce the risk of
damage to the Vac, do not run motor
with float in raised position.
WARNING: To reduce the risk of
injury from accidental starting,
unplug power cord before emptying
the 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.
Emptying the Drum
3. Dump the drum contents into the proper
waste disposal container.
4. If the contents are liquid, you may
dispose by using the drain provided in
the drum for easy emptying. Simply
unscrew the drain cap and allow the
liquid to drain completely out of the Vac
drum.
WARNING: Do not operate
without filter cage and float, as they
prevent liquid from entering the
impeller and damaging the motor.
Drum
Latch
1. To remove the lid to empty contents of
the dust drum simply lift the two drum
latches on the sides 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 area while emptying drum or
changing the filter.
