Test the Automotive-style Horn
(if equipped)
Genie requires that this procedure be performed
every 250 hours or quarterly, whichever comes
first.

operation. The horn is activated at the platform
controls and sounds at the ground as a warning to
ground personnel. An improperly functioning horn
will prevent the operator from alerting ground
personnel of hazards or unsafe conditions.

out the red Emergency Stop button to the on
position at both the ground and platform
controls.
2 Push down the horn button at the platform
controls.
Result: The horn should sound.
Note: If necessary, the horn can be adjusted to
obtain the loudest volume by turning the
adjustment screw near the wire terminals on the
horn.
