OPERATION UNDER UNUSUAL CONDITIONS - CONTINUED
TOWING - CONTINUED
Do NOT exceed a 30-degree angle from straight-ahead position. Keep towline angle to a minimum.
Connect an additional towing machine at rear of disabled machine, to provide additional control and braking capacity.
Remove wheel blocks from disabled machine.
Ensure all personnel and equipment are clear. Provide a ground guide to monitor towing procedure.
Proceed to tow with caution. Gradual, steady machine movement will be the most effective.
Towing with Engine Running.
If transmission and steering are operational, machine may be towed with engine running for a short distance only. An
example is pulling machine out of the mud or to the side of the road to clear traffic.
Operator of disabled scraper must steer machine in the direction of the towline.
Follow instructions and precautions as outlined in Towing with Engine Stopped in this work package.
OPERATION IN EXTREME COLD
Extreme cold causes many problems:
(2) Batteries may freeze or lose their electrical efficiency.
(4) Various materials will become hard, brittle and easily damaged.
(5) The cooling system requires adequate protection from extreme cold.
(6) Fuels, lubricants and antifreeze compounds require special storage, handling, and use.
Refer to FM 9-207 for additional information.
When starting out in extreme cold, follow these procedures:
(1) Be careful when you first start machine. Use cold weather starting procedure and allow engine time to reach
operating temperature. Be alert that tires may be frozen to ground.
(2) Start driving very slowly for about 100 yd (91.4 m). If a problem is noted, notify Unit Maintenance as required.
When parking, follow these procedures:
(1) If machine will be parked for a short period, park in a sheltered area out of wind. If shelter is not available, park
machine so that radiator does not face into the wind.
(2) If machine will be parked for a long shutdown period, try to park on high ground and use planks or brush to make
a raised and relatively dry surface. Keep tires out of snow, water, ice and mud, if possible.
(3) Clean snow, ice and mud from machine as soon as possible after shutdown.
(4) If machine will be parked for a long period of time, have Unit Maintenance prepare machine for storage (TM 5-
(5) Ensure tires are properly inflated.
