CONTACTOR (Overspeed) 7L7349 - Caterpillar

Personal injury or death can occur from operating the front shovel machine without the Falling Objects Guard in place.Do not tilt the bucket back with the boom raised. This can cause material to dump backward over the spill guard onto the operator's station. Dumping backwards usually occurs with the boom in the highest raise position, but dumping backwards can occur when the boom is less than fully raised.To prevent possible injury or death, remove any overhang and watch for sliding material.Never swing a load over a truck cab or over workers.
The bucket cylinders on front shovel machines can be damaged by interference with the bucket linkage, when the bucket has been removed.The stick cylinder must be fully extended to prevent interference.
Make sure that no personnel are on the machine or near the machine in order to prevent any personal injury. Keep the machine under control at all times in order to prevent injury.Reduce the engine speed when you maneuver the machine in tight quarters and when you drive over an incline.Select the necessary travel speed range before you drive downgrade. Do not change the travel speed range while you drive downhill.Use the same travel speed on a downgrade and on an upgrade.When you travel for any distance, keep the stick inward and carry the boom in a low position.When you drive up a steep grade, keep the boom as close to the ground as possible.When you travel uphill or you travel downhill, keep the boom on the uphill side of the machine.
Adjust the operator seat.
Fasten the seat belt.

Select the desired travel speed by operating the travel speed control switch.
Make sure that the position of the upper structure and of the undercarriage is known before you move the machine. The drive sprockets should be at the rear of the machine.Note: The directional steering controls will operate normally if the drive sprockets are at the rear of the machine and the idlers are at the front of the machine and under the cab. When the sprockets are under the cab, the travel controls will operate backward.
Turn the engine speed dial in order to increase the engine speed (rpm) to the desired speed.
Push both travel levers forward at the same time in order to travel forward. If both travel levers are pushed farther, the travel speed at the selected engine speed (rpm) will be faster.Note: If the machine does not operate or if the machine does not travel in a straight line, consult your Caterpillar dealer.
Refer to Operation and Maintenance Manual, "Travel Control" for more information.
When you make turns in soft material, travel in a forward direction occasionally in order to clear the tracks.
Slowly move both of the travel levers or both of the travel pedals to the CENTER position in order to stop the machine.
