SAFETY SENSORS
If the LED indicator light is not green, check the
safety sensors.
• Seat swivel sensor: Seat should be in the locked
position.
• Footrest lower sensor: Check by pushing in on
the safety pan on the footrest.
• Upper foot pan safety sensor: Check by pushing
on the safety pan on the footrest.
• Front foot pan safety sensor: Check by pushing
on the safety pan on the footrest.
• Uphill safety sensor: Ensure that nothing is
blocking upward passage.
• Downhill safety sensor: Ensure nothing is
blocking the downward passage.
If the LED indicator light is still not green after
testing the sensors, turn the unit off and re-check all
the wire plugs. Turn the unit on again and re-check
the LED indicator light cycle. When the LED indicator
light remains green, the lift is ready to operate.
