How to use Helix Curved Stair Lift?

Operating the Curved Stair Lift:

  • Power Supply: The charger should be left plugged and the stair lift should be kept fully charged at all times.
  • Power Indicator Lights: A green light indicates the supply is on. If there is no light, check the wall outlet for power. If still NO light, contact your dealer.
  • Rocker Button: You can start the run by pushing the rocker button in the direction you want to ride. The button is located on your armrest. It must be pushed and held until the lift reaches its destination and stops automatically.
  • Seat Belt & Footrest: Fasten your seat-belt whenever you use the curved stair lift. Make sure you are secure and the seat-belt is firm around your waist. Use the seat belt and footrest at all times when riding the lift.
  • Swivel Handle: Seat swivel handles are located on the both sides of the seat and it helps you in proper landing. Once you reach the destination (top position), pull the swivel handle on the swivel seat and dismount. Seat swivel handle prevents the lift from being operated unless the seat is in its normal, locked position.
  • Obstructions: Safety sensors on the top and bottom of the carriage, and both sides of the footrest will halt the stair lift immediately if they touch an obstruction.
  • Remote Control: Remote Control allows you to move your Stair Lift from its parked position. Just press the up or down button for the desired direction. Keep the button pressed until the lift reaches its final position and stops automatically.
