lubrication intervals, man-hour requirements, and Army Oil Analysis Program (AOAP) for the
M109A2/M109A3/M109A4/M109A5 self-propelled howitzer.
b. Lubrication Intervals and Interval Symbols
The lubrication instructions found in this appendix are presented in grouped sequence by interval. The following lu-
brication interval symbols are used to indicate how often the lubrication service will be performed.
D -- Daily

S -- Semi-Annually
A -- Annually
RDS -- Round fired
c. Maintenance Levels
The maintenance level for all lubrication services in this appendix is Operator/Crew, indicated by “(C)” after the para-
graph headings.
d. Exceptional Operational Requirements
Lubricate more often to compensate for abnormal operation and extreme conditions. High or low temperatures, pro-
longed periods of high rate operation, continued operation in sand, dust, or exposure to moisture may quickly destroy
the protective qualities of the lubricant.
Before performing lubrication checks or services, observe the following.
1
NEVER:
(a) Use incorrect lubricant.
(b) Use too much lubricant.
(c)
Use hydraulic fluid (FRH), MIL--H--46170, in hydraulic system.
2
ALWAYS:
(a) Clean grease fittings before lubrication.
(b) Use this appendix as a guide.
(c)
Lubricate after fording operations.
(d) Ensure vehicle is level prior to checking fluid levels.
