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 dur-
ing 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 opera-
tion is under adverse conditions (e.g., longer than usual operating hours, extended idling peri-
ods, extreme dust, etc.).
Clean area around lubrication points with detergent (Item 4, WP 0020 00) or equivalent
before lubricating equipment. After lubrication, wipe off excess lubricant to prevent accumu-
lation of foreign matter.
Dashed leader line indicates lubrication on both sides of vehicle.
