For the current lubrication order, refer to DA PAM 310-4.
3-3. Detailed Lubrication Information
a. General. Keep all lubricants
in closed containers and stored
in a clean, dry place away from external
heat. Allow no dust, dirt, or other foreign materials to mix with the lubricants. Keep all lubrication equipment
clean and ready to use.
b. Cleaning. Keep all external parts not requiring lubrication clean of lubricants. Before lubricating the
equipment wipe all lubrication points free of dirt and grease. Clean all lubrication points after lubricating to
prevent accumulation of foreign matters.
c. Points of Lubrication.
(1) Service the lubrication points at proper intervals as instructed in the current lubrication order.
(2) Apply pressure lubricant until clean lubricant comes from the part being lubricated.

Shorten intervals to compensate for abnormal operations and severe conditions. During inactive periods,
intervals may be lengthened to the point where lubrication protection is assured.
Section III. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
3-4. Maintenance Forms and Records
Every mission begins and ends with the paperwork. There isn't much of it, but you have to keep it up. The
forms and records you fill out have several uses. They are a permanent record of the services, repairs, and
modifications made on your equipment; they are reports to organizational maintenance and to your
commander; and they are a checklist for you when you want to know what is wrong with the equipment after its
last use, and whether those faults have been fixed. For the information you need on forms and records, see
3-4-1. Preventive Maintenance Checks and Services
a. Do your (B) PREVENTIVE MAINTENANCE just before you operate the equipment. Pay attention to
the CAUTIONS and WARNINGS.
b. Do your (D) PREVENTIVE MAINTENANCE during operation. (During operation means to monitor the
mixer and its related components/ systems while they are actually being operated.)
c. Do your (A) PREVENTIVE MAINTENANCE right after operating the equipment. Pay attention to the
CAUTIONS and WARNINGS.
d. Do your (W) PREVENTIVE MAINTENANCE weekly.
e. Do your (M) PREVENTIVE MAINTENANCE once a month.
f. If something doesn't work, troubleshoot it with the instructions in this manual or notify your supervisor.
g. Always do your preventive maintenance in the same order, so it gets to be a habit. Once you've had
some practice, you'll spot anything wrong in a hurry.
h. If anything looks wrong and you can't fix it, write it on your DA Form 2404. If you find something
seriously wrong, report it to organizational maintenance RIGHT NOW.
i. When you do your preventive maintenance, take along the tools you need to make all the checks. You
always need a rag or two.
Dry cleaning solvent, SD-2 used to clean parts, is potentially dangerous to
