Vacuuming Dry Materials; Vacuuming Liquids; Emptying The Drum - RIDGID WD1685AU0 Owner's Manual

Operation (continued)

Vacuuming Dry Materials

1. The filter must always be in the correct
position at all times to avoid leaks and
possible damage to the 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 must be used 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 (less than 5-10 cm of liquid in the
bottom of the drum) the filter may be
left in place.
2. When picking up larger amounts of
liquid (more than 10 cm of liquid in the
bottom of the drum) we recommend
removing the filter. If the filter is not
removed, it will become saturated and
misting may appear in the exhaust.
WARNING: Do not operate without
a filter cage and float, as they prevent
liquid from entering the impeller and
damaging the motor.
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 the Vac airflow will
cease 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 the Vac
with float in raised position.

Emptying the Drum

WARNING: To reduce the risk
of injury from accidental starting,
unplug the power cord before
emptying the drum.
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 the drum or
changing the filter.
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: 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.
