The M915A4 must receive lubrication with approved lubricants at recommended
intervals in order to be mission-ready at all times.
The Lubrication Chart shows lubrication points, items to be lubricated, the
required lubricants, and recommended intervals for lubrication by the operator/crew. Any

section of the chart.
The KEY and CHARTs A through C provide information needed to select the
proper lubricant for various temperature ranges and uses, and identify the interval.
Recommended intervals are based on normal conditions of operation,
temperature, and humidity. When operating under extreme conditions, lubricants should
always be changed more frequently. When in doubt, notify your supervisor.
