dust and other foreign material from the housing into a sealable plastic

bag.

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 haz-

ardous waste storage requirements.

2c) Clean the laser shuttle track using isopropyl alcohol.

3. Lubricate—

Use Tri-Flow lubricant to lubricate the bearing block and shuttle track.

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.

4. Reinstall—

Reinstall all guards and panels.
