HARNESS AS-ENGINE 3918347 - Caterpillar

Personal injury or death could result when towing a disabled machine incorrectly.Block the machine to prevent movement before releasing the brakes. The machine can roll free if it is not blocked.
Note: Empty the body and lower the body before towing a disabled machine. Do not tow a machine with material in the body and do not tow a machine with the body in the raised position. Failure to dump the load will result in damage to the frame and other components.The towing machine must be as large as the disabled machine. Make sure that the towing machine has enough brake capacity, enough weight, and enough power. The towing machine must be able to control both machines for the grade and for the distance that is involved. The total towing force on the rear or the total towing force on the front must not exceed either of the following structural limits:
773F: 394736 N (88741 lb)
775F: 430294 N (96734 lb)Maintain sufficient control and sufficient braking of the disabled machine when the disabled machine is being moved downhill. This may require a larger towing machine or additional machines that are connected to the rear of the machine that is being towed. This will prevent the machine from rolling away out of control.These towing instructions are for moving a disabled machine for a short distance at low speed. Move the machine at a speed of 2 km/h (1.2 mph) or less to a convenient location for repair. These instructions are only for moving machines. This machine is equipped with spring-applied parking brakes. These brakes are released with hydraulic pressure. If the engine is inoperable, activate the brake release/secondary steering switch. This will operate the motor for the electric powered parking and secondary brake release pump. Refer to Operation and Maintenance Manual, "Towing With Inoperable Engine" for additional information.Shields must be provided on both machines. This will protect the operator if either the tow line or the tow bar breaks.DO NOT allow anyone except the operator to be on the machine that is being towed by a cable.DO NOT use a chain for pulling a disabled machine. A chain link can break. This may cause possible personal injury. Use a wire cable with ends that have loops or rings. Put an observer in a safe position in order to watch the pulling procedure. The observer must be able to stop the procedure, if necessary. Stop the procedure if the cable starts to break or if the cable starts to unravel. Stop pulling whenever the towing machine moves without moving the towed machine.Before towing, make sure that the tow line or the tow bar is in good condition. Make sure that the tow line or the tow bar has enough strength for the towing procedure that is involved. The capacity of the tow line or of the tow bar must be at least 150 percent of the gross weight of the disabled machine. Under certain conditions, failure of the tow line or the tow
