Operating Instructions For Harmar Pinnacle Straight Stair Lift

  1. To turn the stair lift on, press the red “ON/OFF” switch located on the top of the carriage to the “ON”.
  2.  To aid entry to the chair, the armrest on the entry side may be raised. When positioning yourself on the seat at the upper landing, ensure the seat is fully swiveled and locked in position for safety. The seat may be swiveled by depressing the swivel release handle on either side of the seat.
  3. Ensure that you are seated with the seat belt secured and armrests are in down position before operating the lift. To operate the lift, continuously activate the hand control switch on the side in which you wish to travel.
  4. If you release the control switch the lift will stop. Continue to activate the switch or button all the way to the landing. The lift will gently stop at the appropriate, preset point.
  5. To safely exit the lift, remove the seat belt, support yourself by the armrests, rise and step off the footrest. At the upper landing, ensure that the seat is fully swiveled and locked before rising. If you do not intend to use the lift again immediately, the seat and armrests may be folded up to minimize obstruction to people walking on the stairs.
  6. To operate the lift remotely, continuously press the appropriate up or down button on the call/send hand control unit. Like all infrared devices, the signal may be interrupted if the hand control unit is not in the line of sight of the stair lift. If this happens the lift may temporarily stop but will restart immediately, as long as the hand remote is pressed continuously.

Folding Rail
  • Automatic
    - When ascending or depressing the stairs, the chassis will automatically activate the folding rail.
  • Between Uses
    - To keep your landing clear, use the remote control to move the stair lift up into the stairwell. The folding will automatically raise to keep the area clear.

  • Battery Charger
    - The stair lift should be kept fully charged at all times. When the lift stops at an upper or lower landing it will charge automatically. The power supply should be left plugged in at all times and the lift may be left on charge indefinitely, as the charger is intuitive and will not overcharge. Note: The stairlift must be turned on to enable battery charging. Batteries will not charge when the lift is turned off.
  • Care And Cleaning
    - The lift should require no technical maintenance to continue to operate at full capability. There is no grease or other lubricants used in the drive system, and no adjustments should be required. However, the lift should be inspected annually. The lift and rail should be kept clean. Dust can build up on surfaces, and soiling may occur. The seat, footrest, chassis, and upholstery can be cleaned with a damp, soapy cloth followed by a clean, damp cloth. Do not use abrasive cleaners as these can damage the finish. If heavy soiling occurs, clean by scrubbing lightly with a soft brush.
  • Manual Override Operation
    - If your lift fails to operate and the operator does not wish to dismount on the stairway, another person may use the manual override tool to lower (or raise) the lift to a landing. However please follow the instructions on the bottom safety flap of the lift and turn the lift off. Insert the manual override tool into the hole in the lower safety flap until it engages the motor shaft, and turn in the direction indicated.

  • If your lift does not operate, diagnose the problem listening to the beeps emitted
  • An intermittent beep for 30 seconds indicates the lift has been stopped off the charge station. This repeats every 5 minutes until the lift is returned to the charge station. It is recommended that the lift is immediately moved to a strip station (located at either end of the rail).
  • If the beep codes are not able to be cleared and the lift is not working, please contact your local dealer or Harmar and describe the problem. A local technician will need to be contacted to repair the problem if it cannot be repaired over the phone.
  • If no light on the charger may have a problem with AC power or the charger itself
