GrandPrix (GP-7 Series) Two-Post Lifts 37 P/N 5900209 — August 2018 — Rev. C2
Installing Hydraulic Lines
The two metal Hydraulic Lines run along the outside of the Powerside Post. They connect to ports on
the Power Unit on one end and to the two flexible Hydraulic Hoses (on the Top Trough) on the other
end.
The two flexible Hydraulic Hoses were connected to the Hydraulic Cylinder earlier in the installation.
Note: The two metal Hydraulic Lines look similar, but they are not the same. Make sure you orient
them correctly. If you get them backwards, they will not connect correctly to the ports on the
Power Unit.
To install the two metal Hydraulic Lines:
1. Orient the two Hydraulic Lines correctly on the side of the Powerside Post (see drawing below).
At the bottom, one of the two comes out further from the Powerside Post (so that it can reach the
proper port on the Power Unit); that metal Hydraulic Line goes on the right side. The drawing
below shows the correct orientation of the two metal Hydraulic Lines.
The tops of the two metal Hydraulic Lines go under the top of the Top Trough, near the Safety
Cable. Make sure the two metal Hydraulic Lines do not interfere with the Safety
Cable.
2. When the two metal Hydraulic Lines are oriented correctly, fix them in place using the Pipe Straps
on the side of the Powerside Post.
The straps can be rotated to accommodate a better fit.
