PROCEDURE FOR REMOVING CONTAMINATED FILTERS
AND FOR CLEANING OF CONTAMINATED TANK
For the benefit of your health, you should always wear personal protective clothing and respiratory
protection any time you are using or cleaning this vacuum.
1. Unplug machine from power source.
2. Carefully and slowly remove lid only (be sure you have not accidentally lifted the cloth filter bag
at the same time). Set the lid/filter assembly aside.
3. Gently tap the inside of the cloth bag to loosen any particles that may be on the opposite
surface. Do this all around the inside surface of the bag.
4. Gently remove the cloth bag and set aside.
5. Using a cloth, dampened with water (not soaking wet), wipe down all of the exposed surfaces
inside of the tank; put the cloth aside, do not discard.
6. Carefully and "very" slowly, push the paper bag down and off of the intake tube, using the
attached cardboard collar. After the collar is removed from the intake tube, take the damp
cloth and wipe off any surfaces that were not previously cleaned; at this time, re-wipe the
entire inside of the tank and dispose of cloth in the plastic bag.
7. CAUTION: Hazardous materials must be disposed of properly. Never throw contaminated
debris in your usual trash receptacle. Place debris in a plastic bag or can marked
"HAZARDOUS MATERIALS" and take to a hazardous waste handler.
8. For proper assembly of new filters, see "Tank/Filter Set-Up Procedure".
