The manual details a methodical process to safely unpack, mount, and stabilize the unit on a concrete foundation. Field installation steps must follow a strict linear sequence:
2-6.1. Cold Weather Operation a. During cold weather, the viscosity of the grease in the bearings and the hydraulic fluid increases. This causes sluggish operation and increases wear. Check these fluids frequently and change them according to the unit's SOP and the lubrication instructions (LO) for the specific temperature ranges. b. Check tires for proper inflation. Tire pressure drops in cold weather. c. When parking the trailer in cold weather, park on high ground to prevent freezing in place. d. Page 18. 2-6.2. Hot Weather Operation a. During hot weather, check tire pressure frequently. Tire pressure increases in hot weather. Let air out if pressure is too high. b. A "hot weather operation" entry in the "unusual conditions" section. 2-2.6.3. Fording a. The trailer is not designed for deep fording. The maximum fording depth is 30 inches. b. When fording, ensure that the prime mover can handle the drag. Drag is significantly increased when the tires are submerged. c. 30 inches maximum fording depth. ltb 72.5-170d1 b manual
