TIRE 4551779 - 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.
To perform the towing procedure properly, use the following recommendations.This machine is equipped with parking brakes. The parking brakes are applied by springs. The parking brakes are released by oil pressure. If the engine is inoperable or if the brake oil system is inoperable, the parking brakes are applied. The machine cannot be moved.Use these towing instructions for moving a disabled machine over a short distance. Do not move the machine faster than 1 km/h (0.6 mph). Move the machine to a convenient location for repair. Use these instructions for emergency situations only. Always haul the machine if long distance moving is required.Shielding must be provided on the towing machine to protect the operator in case the tow line breaks or the tow bar breaks.Do not allow riders on the machine which is being towed.Before you tow the machine, inspect the condition of the tow line or of the tow bar. Make sure that the tow line or the tow bar is sturdy enough to tow the disabled machine. The tow line or the tow bar must have a strength that is equal to 1.5 times the gross weight of the machine that is being towed. Use a tow bar with this strength or a tow line with this strength to tow a disabled machine that is stuck in the mud. Also, use a tow bar with this strength or a tow line with this strength to tow a disabled machine up a grade.Do not use a chain for pulling. A chain link may break. A broken chain can cause personal injury. Use a wire cable with cable loops or end rings. Position an observer at a safe location. The observer should stop the pulling procedure if the cable starts to break or the cable starts to unravel. If the towing machine moves without the pulled machine, stop the pulling procedure.Keep the tow line angle to a minimum. Do not exceed a 30° angle from the straight ahead position.Quick machine movement could overload the tow line or the tow bar. Overloading the tow line or the tow bar could cause the tow line or the tow bar to break. Gradual, smooth machine movement is recommended.Use the front tie down holes or the rear tie down holes for towing the machine.Normally, the towing machine should be as large as the disabled machine. The towing machine must have enough brake capacity, enough weight, and enough power for the grade that is involved and for the distance that is involved.Connecting a larger machine or extra machines to the machine that is disabled may be necessary. Using a larger machine or extra machines will provide sufficient control for moving a disabled machine downhill and sufficient braking for moving a disabled machine downhill.The requirements for different situations cannot be specified.
