GENERAL INSTRUCTIONS
1. M1 tank brakes must not be set. Transmission selector must be in neutr al.
2. Turret gun must be in the aft travel position, lowered, and locked in the gun elevation travel lock used
for all modes of transportation and a cable (wire rope) used to secure gun tube while in transit. (The gun travel
lock on the turret ceiling will be engaged to the gun breech to anchor the gun tube in zero elevation during
vehicle transit, and the internal turret lock will be engaged in the locked position to prevent turret rotation.)
Turret rotation and gun-elevating controls must be wire-tied, if feasible, to prevent movement of turret and gun.
3. Turnbuckles of front and rear chain tiedowns must be tightened at the same time to avoid disturbing the
tank position.
4. Also applicable are General Rules 4, 5, 7, 11, 15(g), 19, 19A, and 19C in Section 1 of the Rules
Governing the Loading of Commodities on Open-Top Cars and Trailers, published by the Association of
American Railroads. These general rules are also found in TM 55-2200 001-12.
