Vacuuming Liquids; Emptying Dust Drum - RIDGID WD1660 Owner's Manual

3. If your filter is wet but you need to use
the vac to pick up dry material, you can
quickly dry the filter by running the vac
without hose attached for about 10 min-
utes. The clean air rushing through the
vac will help dry the filter.

Vacuuming Liquids

1. When picking up small amounts of liq-
uid the filter may be left in place.
2. When picking up large amounts of liq-
uid we recommend that the filter be
removed. If the filter is not removed, it
will become saturated and misting may
appear in the exhaust.
CAUTION: Do not remove the filter
cage or float. It is there to shut off air-
flow when the drum is full of liquids.

Emptying Dust Drum

WARNING: To reduce the risk of
injury from accidental starting,
unplug power cord before emptying
the drum.
1. To remove the lid to empty contents of
the dust drum, simply lift the two drum
latches at the front and rear of the dust
drum and lift the lid assembly up and off
the dust drum and set to the side.
NOTE: Do not pick up the lid assembly by
lifting on the handle to the detachable
blower. Lift the lid assembly by the
latches. This will ensure that the detach-
able blower and the lid will not separate
during removal of the lid assembly.
2. Lay the lid assembly upside down on a
clean dry area while emptying the drum
or changing the filter.
3. Dump the drum contents into the proper
waste disposal container.
3. When the liquid in the drum reaches a
predetermined level, the float mecha-
nism 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 avoid damage to the
vac do not run motor with float in raised
position.
4. If the contents are liquid, you may dis-
pose by using the drain provided in the
drum for easy emptying. Simply
unscrew the drain cap and allow the liq-
uid 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 comfort-
ably.
