2-9. CLEANING INSTRUCTIONS (continued).
Hands should be kept free of grease, which can collect dust and dirt,
WARNING
Compressed air used for cleaning purposes shall not exceed 30 psi (207 kPa). Use
only with effective chip-guarding and personal protective equipment (e.g., goggles/
shield, gloves).
Blow-dry metal parts with compressed air or wipe pads dry with clean rags.
Rubber parts should be washed with a soap solution and dried with clean rags.
CAUTION
Do not steam-clean electrical components. Moisture and condensation in electrical
wiring can cause short circuits and other damage.
Wipe electrical harnesses completely dry with clean rags.
Remove corrosion or rust by sandblasting or vapor-blast cleaning, or with crocus cloth. Use the method that will not
damage the surface being cleaned. Crocus cloth should be used to remove corrosion and rust from polished surfaces
only. Make sure critical dimensions are not changed when using crocus cloth.
Inspect screw thread inserts for damaged or missing keys, damaged threads, or looseness. Replace any damaged
screw thread insert.
Inspect threaded holes for damaged or knurled threads. Repair damaged threads with thread restorer file by chasing
on a lathe or using tap and die.
Always measure a component when tolerances are given to make sure the component is still serviceable.
2-10. LUBRICATION INSTRUCTIONS.
Unless otherwise directed, apply a light coat of lubricating oil to all metal parts after cleaning and inspection. This
prevents rusting and aids assembly. To ease connection, silicone compound maybe used on connectors of electrical
wires.
Lubricate parts during and after assembly in accordance with lubrication instructions and intervals given in TM 9-2350-
287-10 and TM 9-2350-287-20-2.
