steps:
1. Check guards and covers. Repair any that are damaged. Replace any that are
missing.
2 Wipe all exposed air bearing paths and the work table surface with alcohol
and a clean, soft cloth. Use clean medical gauze or the equivalent.
3. Check the air supply. It should be 3.7 BAR (55 psi).
4. Check the air filters and drain or replace, if necessary.
CAUTION
Never attempt to remove any portion of the filtration system without
disconnecting the air supply to machine and bleeding off system pressure.
