Maintenance
Cleaning Vac Filter
WARNING: To reduce the risk of
injury from accidental starting,
unplug power cord before changing
or cleaning filter or foam pad.
Be sure to dry the filter before storing or
picking up dry debris.
IMPORTANT: After cleaning, check the fil-
ter for tears or small holes. Do not use a fil-
ter with holes or tears in it. Even a small
hole can cause a lot of dust to come out of
your vac. Replace it immediately.
NOTE: The filter is made of high quality
paper designed to stop very small particles
of dust. The filter can be used for wet or dry
pick up. Handle the filter carefully when
removing to clean or installing it. Creases in
the filter pleats may occur from installation
but will not affect the performance of the fil-
ter.
Removal
To remove the filter for cleaning or replace-
ment, unscrew the filter nut from the filter
cage, remove filter plate and lift off filter.
IMPORTANT: To avoid damage to the
blower wheel and motor, always reinstall the
filter before using the vac for dry material
pickup.
CAUTION: Do not remove the filter
cage or float. It is there to shut off air-
flow when the drum is full of liquids.
Dry Filter
1. Light cleaning of some dry debris from
the filter can be accomplished without
removing the filter from the vac. Simply
slap your hand on top of the handle
while the vac is turned off.
2. Clean the filter in an open area. Clean-
ing SHOULD be done outdoors and not
in the living quarters.
3. Remove filter from vac. Gently tap the fil-
ter against the inside wall of your dust
drum and the debris will loosen and fall.
4. For thorough cleaning of dry filter with fine
dust (no debris) you may run water
through it as described under “Wet Filter”.
Wet Filter
Remove filter from vac, run water through
the filter from a hose or spigot. Take care
that water pressure from the hose is not
strong enough to damage filter. Remember:
To dry a filter quickly, reinstall the filter on
the vac and allow the unit to run for 10 min-
utes. The clean air rushing through the filter
will dry it.
Installation
Refer to “Filter Assembly”.
Allow the filter to dry before reinstalling and
storing the vac.
