The M992A1 is authorized to tow only one vehicle at a time and only when the
other vehicle is disabled, or when towing to start engine.
In an emergency you can tow a vehicle for a short distance (not more than 1/4
mile) without disconnecting universal joints. Put transmission selector lever in
neutral position before starting towing operation. Do not tow disabled vehicle
over 10 mph. Be careful not to accidentally shift into gear.
The following precautions should be followed to ensure safety to personnel and to prevent damage to equipment:
Vehicle engines will be shut off and brakes applied while tow cables are being connected or disconnected.
There must be an observer to assist driver when rigging vehicle and during towing operations.
* When tow bars or cables are used, a second vehicle is required when
descending a grade of 20 degrees or more, or if road conditions require
additional power. Do not exceed 10 mph.
When universal Joints are disconnected, you cannot steer or brake. Use
tow bar only.
Stow universal joints and flanges where they will remain clean and free
of dirt. Failure to do so may result in damage to equipment.
