If you will be mounting the track so that it stops 
at the bottom step instead of the lowest land-
ing, you MUST drill  a hole through the side of 
the track and insert at least a 1/4"-20NC bolt 
(supplied) on each side of end of the track to 
act as a mechanical stop in case of complete 
mechanical or electrical failure.

Verify there is adequate 

clearance at the lower land-
ing for the track and seat.  
Minimum clearance required 
beyond the bottom step is 
10" plus the depth of one 
step (see Fig. 1).

B.  DETERMINE WHERE THE TRACK WILL BE 

INSTALLED

Double check the orientation of your stair lift.

The chassis box of your stair lift will be marked as 
either a Left Hand unit or a Right Hand Unit.

Stand at the bottom of the staircase on which you will 
be installing the lift. A left hand unit will be traveling up 
the left side of the staircase and a right hand unit will 
be traveling up the right hand side of the staircase.

If the handedness of the unit is consistent with the lift 
you ordered, continue the installation. If the handed-
ness is wrong, please contact the authorized seller 
fo the unit.
