How to use Harmar SL300 Pinnacle Stair Lift?

  1. To turn the inside 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 swivel is controlled by pressing the swivel release handle located at the side of the seat bottom. The footrest may be lowered to assist with entry and to keep your feet properly positioned during transport

  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. At the upper landing, swivel the seat away from the staircase until the seat is fully swiveled and locked, and remove your seat belt before rising. To safely exit the lift, remove the seat belt, support yourself by the armrests, and 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. Hand control units are typically located at the upper and lower landings of the staircase

Maintenance of Harmar SL-300 Pinnacle

  • Battery Charger
    • The stairlift should be kept fully charged at all times. When the lift stops within three (3’) feet 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
