of load applied to register a positive weight value.
The load pin should extrude from the outside of the frame 4 inches.

DO NOT overheat the load pin when tack welding. This may damage the load pin. Do not exceed 140° F.
12. Remove the load pin from the frame.
Load pin should be easily removed by hand. If not, use a wood block (or similar material) to cushion the
load pin, and tap lightly to remove.
Do NOT strike the load pin directly, it may cause damage to the load pin.
13. Skip-weld the collar to frame with four welds of 1 inch each, is adequate. However if the installer prefers,
the entire collar can be welded in place. Allow collar to cool before proceeding to next step. Ensure there
are no weld remnants inside the collar or pivots. Remove any such residuals.
