FINAL TESTING
Test Armrest Control Switch
1. Ensure that the unit travels correctly by
operating the armrest control switch while
standing in front of the unit.
2. Depress the switch in the upstairs direction to
move up. The lift will beep, wait three seconds
and begin to smoothly accelerate upwards. The
lift will continue to move upwards as long as the
switch is depressed.
3. Release the switch and the lift will come to an
immediate stop.
4. Depress the switch in the downstairs direction
to move down. The lift will beep, wait three
seconds and begin to move downwards.
5. Release the switch and the lift will come to an
immediate stop.
6. Run the chair all the way up and down the rail
to ensure that the top of the seat back has
at least a 1/2
" clearance from the wall and any
obstructions.
Tighten Brackets
1. Install and fully tighten the rail bracket mounting
screws (four screws per bracket). For hardwood
stairs, drill a pilot hole first. For plywood or
particle board stairs, take care to prevent
stripping.
Set Upper and Lower
Travel Limits
1. Test the lower travel limit by operating the lift
downward, keeping the switch depressed. The
unit should begin to decelerate about 3
" from its
final resting position and stop clear of the floor.
2. The final stopped position can be adjusted
to accommodate the height of the user by
repositioning the limit cam located in a slot in
the rail.
3. Use a 5/64 " Allen wrench to loosen the set screw
in the limit cam. Adjust the limit cam up or down
and retighten the set screws. Repeat the above
steps until the lift stops in the desired position.
4. Repeat the above steps to set the upper limits.
For safety, the footrest should be set at least
level with the upper landing.
5. The optimum position is met when the seat
height above the floor is the same at the top and
bottom of the stairs.
Test Safety Stop Switches

upward and downward ends of the chassis
