Vacuuming Dry Materials; Vacuuming Liquids; Emptying Dust Drum - Emerson RIDGID WD40700 Owner's Manual

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 dust 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 2 inches (5 cm)
of liquid in the bottom of the Drum)
the Filter may be left in place.
2. When picking up large amounts of
liquid (more than 2 inches (5 cm)
of liquid in the bottom of the Drum)
we recommend that the Filter be
removed. If the Filter is not removed,
it will become saturated and misting
may appear in the exhaust.
WARNING:
!
Do not operate without 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 airflow. 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.

Emptying Dust Drum

WARNING:
!
To reduce the risk of injury from
accidental starting, unplug power
cord before emptying the drum.
1. To remove the Powerhead to empty
contents of the Dust Drum, simply lift
the two Drum Latches on the side of
the Vac and lift the Powerhead up and
off the Dust Drum and set to the side.
2. Lay the Powerhead 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.
