WARNING
Dry cleaning solvent P-D-680 is toxic and flammable. Always wear protective goggles
and gloves, and use only in a well-ventilated area. Avoid contact with skin, eyes, and
clothes, and DO NOT breathe vapors. DO NOT use near open flame or excessive
heat. The solvent's flash point is 100F-130F (38C-59C). If you become dizzy
while using cleaning solvent, immediately get fresh air and medical help. If solvent
contacts eyes, immediately wash your eyes and get medical aid.
b. Use dry cleaning solvent (Item 10, Appendix E) to clean grease fittings, lubrication points, and
surrounding areas before lubricating.
c. When lubricating at a grease fitting, apply enough grease to purge old grease from the lubricated
area. When old grease oozes from the grease fitting, purging and lubrication are adequate.
