CASTER INSTALLATION: WP-3636, WP-3648, & WP-4848
Improperly installed, utilized, or maintained casters could make the platform unsafe to use. To
reduce the likelihood of serious injury:
 READ EACH INSTRUCTION BEFORE BEGINNING THE INSTALLATION.
 Inspect the casters regularly for damage and to verify that the caster stem is still inserted fully and that it is securely
held inside the post.
 Only use the casters on flat, even, solid surfaces.
 DO NOT move the platform when loaded with equipment or personnel. Only move the platform by means of the
casters if completely unloaded AND unoccupied.
 Forklift operator: DO NOT lower the platform onto the casters at a rate greater than one foot per second. Gently
lower the platform onto the casters to avoid damaging them.
1. Verify that the bottoms of all four of the handrail posts are undamaged and free of foreign material (inside the
posts).
2. Raise the work platform high enough to allow the casters to be inserted into the bottom of each of the four posts.
3. Examine each caster; verify that each has a plastic spacer, a black rubber expansion sleeve, and a knurled nut as
shown in Figure A.
4. Hold onto the 2½" tightening hub at the top of the caster rig with your hand and snug the knurled nut against the
top rubber expansion sleeve.
5. Insert the caster stem into the bottom of the post until the tightening hub is up against the bottom of the handrail
post.
6. Turn the tightening hub counterclockwise. If the hub doesn't tighten, apply side pressure to the caster while
turning the hub.
NOTE: The tightening hub must maintain contact with the
bottom of the corner handrail post during tightening.
7. After hand-tightening the hub, pull down on the caster rig
to verify that the caster is secured in the post.
