MAINTENANCE & TIPS
Disconnect electrical components and drain you air system before performing maintenance.
GENERAL AIR HORN SYSTEM MAINTENANCE
• Check your air horns for debris when appropriate and at least once a month and clean when necessary.
• Drain your air system at least every other week, to remove any condensation buildup on the inside of you air tank.
• Make sure you air compressor is clean and free from debris at all times.
• Periodically change your two stage air filter on your compressor.
TIPS
• Make sure your engine is running when you air compressors are in use to insure proper voltage and to prevent damage to your
system.
• Do not run your compressor above its maximum rated working pressure. Doing so will not only void you warranty, but may also
damage your compressor.
• The air horns are pre-tuned to a locomotive chord and to their loudest possible tone. Do not adjust the tuning screw on the
horns. Doing so will void your warranty and may damage the horns if improperly adjusted.
