Cleaning/Inspection.
WARNING
·
Drycleaning solvent (P-D-680) is TOXIC and flammable. Wear protective
goggles and gloves; use only in a well-ventilated area; avoid contact with skin,
eyes, and clothes and do not breathe vapors. Keep away from heat or flame.
Never smoke when using solvent; the flash point for type I drycleaning solvent
is 100°F (38°C) and for type II is 140°F (60°C). Failure to do so may result in
injury or death to personnel. P-D-680 type III is a substitute for types I and II in
this application. The flash point for type III is 200°F (93°C).
·
If personnel become dizzy while using cleaning solvent, immediately get fresh
air and medical help. If solvent contacts skin or clothes, flush with cold water.
If solvent contacts eyes, immediately flush eyes with water and get immediate
medical attention.
·
Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa).
Use only with effective chip guarding and personal protective equipment
(goggles/shield, gloves, etc).
CAUTION
Do not allow bearing assembly to spin freely when drying with compressed air;
turn bearings slowly by hand. Failure to do so may result in damage to race and
balls.
(1)
Clean all parts with drycleaning solvent and dry with compressed air.
(2)
Turn outer race of bearing and inspect for roughness.
