Section II. PREVENTIVE MAINTENANCE CHECKS AND SERVICES
a. 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 mixer; 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 mixer after its last use and whether those
faults have been fixed. For the information you need on forms and records, see TM 38-750.

3-4. General Maintenance Procedures.
a. Cleanliness. The mixer body will operate practically trouble free if the proper emphasis is placed on cleaning and
lubricating. Hardened cement in any area will cause operational problems, as will improper lubrication. Cleanup is
relatively easy if done immediately after shutting down the unit but becomes much more difficult if It is put off. Dirt, greas e,
oil and debris only get in the way and may cover up a serious problem. Use dry cleaning solvent (SD-2) on all metal
