Figure 3.2 Spring Installation
Note: It may be easier to install springs with ramps tightened at the top of the slotted
holes on the ramp mount bracket. Be sure to loosen bolts after ramp install so
ramps will slide freely on slots.
4. Slide the spring installation tool through the guide rod clevis so end of tool is
resting solidly on the frame channel.
5. Lift the tool to compress the spring and guide the clevis over the tab on the
frame so the bolt holes align.
6. Install a 1/2” x 2-1/4” bolt and a nylock nut in the order shown.
7. Repeat for all 4 lift-springs.

WARNING
Compression springs store large amounts of
energy and will expand with great force when
released. Use caution when compressing
springs to avoid serious injury.
Ensure tool is in good condition and firmly
seated.
Stand clear of the path of the spring in case it
is accidentally released.
