This will ensure a longer machine life and more effective cleaning. Please return the vacuum to the Preservation Dept. with a vacuum return slip marked to request filter changing and that you want the vacuum returned to yourself. Preservation staff can provide instruction on filter replacement for large stack cleaning projects. A filter record on each vacuum will be updated by Preservation staff. These are for dry vacuuming only.
Supervisors are responsible for monitoring vacuuming activity.
If the vacuums are heavily used, the cone filter should be changed once a week, even if the canister is not full . Keep a record of filter changes. Lift side clamps and top unit. Gently set the motor unit down. Lift the canister unit from the wheel ring and empty in the dumpster.
