connected together and provides additional
length for more reach.

ing capability to work site. Provides the
means of attaching extension wands and
nozzles.

to connect the blower nozzle to the exhaust
of the power assembly.

Vacuuming Dry Materials

1. The filter must 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 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.
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.
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.

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.
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.
