Operation in Snow....................... 2-50 Conditions .................................... 2-50 OPERATION IN EXTREME HEAT 1. Do not park dolly set in sunlight for long periods of time. Heat and sunlight shorten the life of tires. If possible, shelter or cover dolly set. 2. Maintain correct tire inflation pressure. OPERATION IN EXTREME COLD 1. Extreme cold can cause lubricants to thicken or congeal, insulation to crack, and cause electrical short circuits, and construction materials to become hard, brittle, and easily damaged or broken. Tow the dolly set very slowly for the first 100 yards. Normal operation temperature for the lubricant should be reached by then. 2. Tires may freeze to the ground or have a flat spot if under inflated. 3. Brake shoes may freeze to the brake drums and need to be heated to prevent damage to mating surfaces. Check brakes before operation. After moving the initial 100 yards, normal operating temperatures should be reached. 4. Refer to FM 9-207 and FM 21-305 for special instructions on driving hazards in extreme cold. 5. When parking short term, if high, dry ground is not available, place a footing of planks or brush under dolly wheels. 6. Clean all parts of the dolly set immediately after operation. OPERATION IN SALTWATER AREAS Saltwater will cause rust and corrosion. Clean, inspect, and lubricate often. OPERATION ON ROCKY TERRAIN 1. Tires must be fully inflated to 50 psi (344 kPa) when moving on rough or rocky terrain. Underinflation will cause internal ruptures of the tires and damage to the tubes. 2-49
