Hang the stair assembly on the platform in the desired location. Adjust the vertical position of
the riser on the legs and top posts by loosening and retightening the 3/8”-16 set screws in the
riser corner pockets until the distance from bottom tread to ground is approximately the same
distance from top tread to the platform walking surface and the stair treads are level. After the
riser has been positioned and leveled, tighten all set screws in the corner pockets for stair top
posts and legs securely (FIG. 6).

Make sure the stair assembly is positioned flush against the platform side rail and use the
holes in the stair hanger tabs as a template to drill 1/8” holes through the top wall of the side
rail. Fasten the stair assembly to platform using two provided 1/4" pan head self-tapping
screws (FIG. 7). NOTE: If the stair will be used with a Connector – HR Platform to S
tair
(MHRPSC), a minimum of 6” is required between the platform vertical post and stair top post.
