Use and Care Manual

HD-9 Series Four-Post Lifts 25 P/N 5900123 — Rev. M1 — March 2020
To install the Ladders and the Top Caps:
1. Take a Ladder and slide it down the back of the Post, with the Bolt Hole end at the bottom.
Make sure the Ladder goes through both Slots on each Gusset . There is a Slot at the
top of the Gusset and another Slot at the bottom of the Gusset, both formed by the Slide Blocks.
⚠ WARNING It is easy to see the top Slot created by the Slide Blocks. It is difficult to see the
bottom Slot, but it is
required that the Ladder goes through both Slots. If the
Ladder misses a Slot or the Slide Blocks were not installed correctly, your Safety
Locks will
not function correctly.
2. Install the remaining Ladders the same way.
3.
Moving to the top of the Ladders , put the Stop Nut on the Threaded Bolt at the top; move
the Stop Nut down half an inch from the top of the Post.
4. Put the Top Cap onto the top of the Post: put the Threaded Bolt on the top of the Ladder through
the appropriate hole, put the tabs on the side of the Top Cap inside of the Post, and secure the
Top Cap on both sides with one Hex Head Bolt and one Nyloc Nut per side.
5. Once the Top Cap is secure, move the Stop Nut up until it contacts the underside of the Top Cap,
then add a Flat Washer and Nyloc Nut to the top of the Top Cap and tighten it. Only hand tighten
at this point.
You are looking for about an inch of thread above the top of the Top Nut.
Note: The other hole in the middle of the Top Cap is for the Lifting Cable, installed later.
6. Install the remaining Top Caps the same way.
