WARNING

Clean all parts in a well-ventilated area. Avoid inhalation of solvent fumes and prolonged exposure of skin to cleaning

solvent. Dry cleaning solvent, P-D-680 or P-S-661, used to clean parts is potentially dangerous to personnel and property.

Do not use near open flame or excessive heat. Flash point of solvent is 100 F. - 138 F. (38 C.- 59 C.).

Clean ball and roller bearings by replacing them into a wire basket and then immersing them into a container of fresh cleaning solvent (Fed.

Spec. P-D-680). Agitate the bearings in the solvent to remove all traces of old lubricants. After the bearings are cleaned, allow them to air

dry.

Inspect the bearings for signs of scoring, cracked races, signs of overheating, and binding operation.
