Use and Care Manual

HD-9 Series Four-Post Lifts 36 P/N 5900123 — Rev. M1 — March 2020
Before routing the Cables, extend the Piston on the Hydraulic Cylinder.
To extend the Piston:
1. Remove the Shipping Plug from the Return Line Connector.
The Return Line Connector is on the Cylinder end closest to where the Power Unit will be.
2. Attach an air pressure source to the Return Line Connector.
3. Use the air pressure to extend the Hydraulic Cylinder’s Piston and Retaining Plate.
Do not exceed 50 psi .
If the Cylinder does not move, stop using air pressure; instead, use a pulling device (such as a
Come Along Tool) to extend the Piston and Retaining Plate; be care not to damage the Piston.
4. Reinstall the Shipping Plug to the Return Line Connector.
The following procedure assumes you have nearby the four Lifting Cables and Sheaves you removed
prior to installing the Runways.
To route Lifting Cables A and C:
1.
Starting with Lifting Cable A , move the entire thing to just under the Large Window it goes
through, near the bottom of Post A.
Check the label to make sure you have the correct Lifting Cable.
2. Remove the Nut and Washer from the Threaded End (but keep it nearby, you will need it soon).
3. Route the Threaded End of Lifting Cable A into its Large Window on the Crosstube, push it
towards Post A, and then pull the Threaded End out of the Crosstube at the bottom of the Gusset.
4. Route the Threaded End of Lifting Cable A under where the Gusset Sheave will go when it is
reinstalled, then route it up past the top of the Crosstube Gusset.
The following drawing shows how to route the Lifting Cable through the Gusset.
Important: When routing a Lifting Cable in its Post, the Cable must go
under the Gusset
Sheave and be on the side of the Slack Safety Sheave. When the Cables are pulled
tight, the Cable prevents the Slack Safety from engaging, which is what you want. If
the Cable is
not in this exact location , the Slack Safeties will not work
correctly.
