GENERAL LUBRICATION PROCEDURES - CONTINUED

Recommended intervals are based on normal conditions of operation, temperature, and humidity. When operating under

extreme conditions, such as high or low temperatures or exposure to sand or dust, lubricants should always be changed

more frequently. Lubricants that have become contaminated will be changed regardless of interval. When in doubt,

notify your supervisor.

Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat. Keep container covers

clean and do not allow dust, dirt or other foreign material to mix with lubricants. Keep all lubrication equipment clean

and ready for use.

Maintain a good record of all lubrication performed and report any problem noted during lubrication. Refer to DA Pam

738-750 for maintenance forms and procedures to record and report any findings.

Keep all external parts of equipment not requiring lubrication free of lubricants. Before lubrication, wipe lubrication fit-

tings with a clean rag (Item 31, WP 0305 00) and detergent (Item 14, WP 0305 00). After lubrication, wipe off excess oil

or grease to prevent accumulation of foreign matter.

Refer to FM 9-207 for lubrication instructions in cold weather.

Refer to AR 70-12 for use of standardized fuels and lubricants.

Engine and transmission oil filters shall be changed when:

they are known to be contaminated or clogged;

at prescribed hardtime intervals.

Engine oil and transmission fluid must be sampled initially at or 90 days of operation as prescribed by DA Pam 738-

750.

For equipment under manufacturer's warranty, hardtime oil service intervals shall be followed. Intervals shall be short-

ened if lubricants are known to be contaminated or if operation is under adverse conditions (i.e., longer-than-usual oper-

ating hours, extended idling periods or extreme dust).

GENERAL PMCS PROCEDURES

Always perform PMCS 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. If any deficiency is discovered, perform the appropriate troubleshooting task in Chapter 2 of this man-

ual. If any component or system is not serviceable, or if the given service does not correct the deficiency, notify your

supervisor.

Before performing preventive maintenance, read all the checks required for the applicable interval and prepare all tools

needed to make all checks. Have several clean rags (Item 31, WP 0305 00) handy. Perform ALL inspections at the appli-

cable interval.

Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem. Clean as you work

and as needed. Use detergent (Item 14, WP 0305 00) and water when you clean.

Rust and Corrosion. Check metal parts for rust and corrosion. If any bare metal or corrosion exists, clean and

apply a light coat of lubricating oil (Item 22, WP 0305 00). Report it to your supervisor.

Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing, bent or broken condition.

You can't try them all with a tool, but look for chipped paint, bare metal or rust around bolt heads. If you find one

you think is loose, tighten it.

Welds. Look for loose or chipped paint, rust or gaps where parts are welded together. If you find a bad weld, report

it to your supervisor.

Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken connec-

tors. Tighten loose connectors and ensure that the wires are in good condition.
