D4-9 / D4-9X Four-Post Lifts 19 P/N 5900251 — Rev. A1— August 2021
Orientation Issues
Important: Before continuing with the next section, you must decide how you want to position the
Runways, as that affects the orientation for the Posts and Top Caps.
Before installing your Lift, you need to understand three orientation issues:
• Runways. The two Runways are
not
the same. One has a Hydraulic Cylinder under it and is the
starting point for the Lifting Cables. The Runway with the Hydraulic Cylinder under it is the
Powerside Runway and
must
be installed next to the Power Post.
If you have not already chosen your Power Post location, return to Selecting your Power Post
Location and make the choice.
• Posts. The four Posts are
not
the same; two have their Safety Lock Holes on the left, the other
two have their Safety Lock Holes on the right (when you are looking at them straight on).
Each D4-9 comes with two “Right” Posts and two “Left” Posts.
When you put the Posts into position, make sure that all four Posts are oriented so that the Safety
Lock holes are on the
outside
of the Lift.
View of Posts is from between the two Runways; view of Lift is from above. Not all components
shown. Not necessarily to scale.
This orientation is
required
so that the Safety Locks in the Crosstubes line up with the Safety
Lock Holes in the Posts.
NOTICE The Power Post must be a “Right” Post, but you can use either “Right” Post as the Power
Post.
• Top Caps. All four Top Caps must be oriented so that the extended corner is angled in towards
the middle of the Lift. The “right” Top Caps must be installed on the “right” Posts and the “left” Top
Caps must be installed on the “left” Posts.
Important: The four Top Caps look very similar but they are
not the same
.
The drawing in Installing the Top Caps shows and describes how to determine if a Top Cap is
a right or a left.
