Backup Alarm
Backup Alarm - The alarm sounds when the transmission direction selector is in the REVERSE position. The alarm alerts the people behind the machine that the machine is backing up.
The backup alarm is on the rear of the machine.
A three-position switch is on the rear of the backup alarm. The three positions on the switch are high, low, and medium. The three-position switch regulates the volume of the alarm.
The alarm is set from the factory at the highest sound level. The setting should remain on high, unless the job site requires a lower sound level.
