Your purchase of a Wolo Train Horn is the choice to compliment your vehicle. Wolo’s products are manufactured with the
finest materials. Each horn is tested to insure it meets all manufacturing specifications, before it is packaged. If you need
help installing your new Wolo horn, our technicians are available to answer your questions, Monday thru Friday, 9 AM to
4 PM EST at 1-888-550-HORN (4676).
HORN INSTALLATION (Fig. A)
1. Locate a mounting location that is a solid metal surface
such as the vehicle’s frame or chassis to help prevent
excessive vibration, which could damage the horn.
IMPORTANT: Do not mount horn on a plastic fender well
or on flexible material. For best results, the front of the
horn should be unobstructed so that the sound can carry
straight ahead.
2. Use the base of the horn as a template, mark the hole
locations and drill to size 5/16".
3. Place the gasket between the mounting surface and the
base of the horn.
4. Secure the horn with the hardware provided and tighten
evenly.
