around and under heater. Look for smoke in heated air stream (excessive smoke is

observed (TM 9-2350-294-20-1-1, WP 0121-00)).

If leaks are found:

a. If fuel leaks are found in steps one (1) and two (2), repair at unit level.

b. If fuel leaks are found in steps four (4) through six (6), remove heater and turn into

appropriate level maintenance for repair.

Repair of any internal heater component is not authorized at unit level. If repairs are needed,

turn component in to appropriate level maintenance facility.

Crewmembers must always be aware of the warning signs of potential fire, abnormal smells,

smoke, flames, or fuel leaks while operating their vehicles. If any area of your vehicle has

questionable shortcomings, report them to maintenance.

Operators must remain with the vehicle during heater operation to detect and suppress fires.

Crewmembers must physically rehearse fire and evacuation drills on a regular basis in

accordance with the operator's manuals and applicable field manuals. As duty positions change,

so do individual responsibilities during fire and evacuation. Institute these drills in your routine

training activities and practice them until they become second nature.

Unit Commanders, contact your local TACOM Logistics Assistance Representative (LAR) or

your State Surface Maintenance Manager for assistance if necessary.
