Important Safety Information

  • WARNING
    • See the Important Safety and Product Information guide in the product box for product warnings and other important information.
    • You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid navigational hazards and never leave the helm unattended.
    • To avoid possible personal injury and damage to your boat, the autopilot system should be installed by a qualified marine installer. Specific knowledge of marine steering and electrical systems is required for proper installation.
  • CAUTION
    • To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.
    • When in use, beware of hot surfaces on the heat-sink, motor, and solenoid components to avoid possible personal injury.
  • NOTICE
    • The drive unit movement must be limited by physical end stops. Failure to install end stops will cause the drive unit to act as a travel limiter and will damage the drive unit.
    • When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
