Remove safety goggles.
WARNING: Numerous government regulations apply to the stor-
age of hazardous waste. Ensure that contaminated filters are
properly labeled and stored in your hazardous waste storage
area. Also, make sure that they are not stored on your site longer
than government regulations allow (the typical limit is 90 days).
Check your government (local, state, and federal) regulations for
hazardous waste storage requirements.
3. Lubricate—
3a. Lubricate the bearing block and shuttle track with Tri-Flow
lubricant.
Note: Use a small amount of lubricant, just enough to allow the
bearing block to move freely on the track. Too much lubricant will
aid in the build up of contamination and cause stalling.
