This Lubrication Chart is for the operator/crew (C). Lubrication intervals (on-condition
or hard time) are based on normal operation. Lubricate more during constant use and less
during inactive periods. Use correct grade of lubricant for seasonal temperature expected.
For equipment under manufacturer's warranty, hard time oil service intervals shall be
followed. Intervals shall be shortened if lubricants are known to be contaminated or if
operation is under adverse conditions (e.g., longer than usual operating hours, extended idling
periods, extreme dust, etc.).
Dry cleaning solvent 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 solvents flash point is
100°F-138° F (38°C-59° C). 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.
Clean area around lubrication points with dry cleaning solvent (Item 16, Appendix D)
or equivalent before lubricating equipment. After lubrication, wipe off excess lubricant to
prevent accumulation of foreign matter.
Dashed leader line indicates lubrication on both sides of vehicle.
