VALVE & MTG GP-MAIN CONTROL 3976463 - 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: The engine must be operable or an auxiliary power unit must be available in order to provide steering capability. Refer to Operation and Maintenance Manual, "Towing With Inoperable Engine" for additional information.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 on the front of an Off-Highway Truck must not exceed either of the following structural limits:
40 percent of the gross machine weight
1110000 N (249540 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, move the brake release switch to the ON position. 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 the towing device breaks.DO NOT allow anyone except the operator to be on the machine that is being towed by a cable.Use a suitable towing device as a tow line, a tow bar, or a trunnion pin system. Make sure that the towing device is properly rated for the towing procedure that is involved. Make sure that the towing device is in good condition. The capacity of the towing device must be at least 150 percent of the gross weight of the disabled machine. Under certain conditions, failure of the towing device will occur if the towing device is less than 150 percent capacity. A machine that is retrieved from the mud or a machine that is being towed up a grade are examples of these conditions.Put an observer in a safe position in order to watch the towing procedure. The observer must be able to
