Audio Warning System
All models are equipped with an audio warning system as standard equipment to alert the
operator of insufficient engine oil pressure, excessive engine temperature, or a low drive
unit lubricant condition. The following items are particularly noteworthy for proper
installation of the system:
!
WARNING
Fire or explosion hazard. The horn is not external ignition-proof, therefore, do not mount
the horn in the engine or fuel tank compartments.
• Select mounting location where alarm is out of the elements, yet can be readily heard.
• Alarm should be within 46 cm (18 in.) of instrumentation to allow connection to switched
side of ignition switch.
• Coat electrical connections with Liquid Neoprene to avoid corrosion.
• Small transparent decals (2) provided should be installed on engine water temperature
gauge and oil pressure gauge.
• Place large decal on the dash within easy view of the operator.
