V & LINES GP 1926101 - Caterpillar

backup alarm alerts the personnel behind the machine that the machine is backing up. The backup alarm is located at the rear of the machine.
Park the machine on a level surface and stop the engine.
Make sure that the area behind the machine is clear of personnel and clear of obstacles. Make sure that the parking brake is engaged.
Turn the engine start switch to the ON position. Note: Do not start the engine.
Turn the fan speed switch to the OFF position and turn off the entertainment radio (if equipped). Open a door or a window.
Move the transmission control to the REVERSE position and listen for the backup alarm. The backup alarm should sound immediately. The backup alarm should continue to sound until the transmission control is moved out of the REVERSE position.
If the machine is equipped with an audio-visual backup alarm, a warning light on the rear of the machine will flash when the transmission control is in the REVERSE position. A separate person should be positioned at a safe distance from the rear of the machine in order to check for proper operation of the warning light.
Move the transmission control to the NEUTRAL position.
If the backup alarm did not function, or if the backup alarm did not function properly, contact your Caterpillar dealer.
