the auxiliary hydraulics, engage the parking
brake, and lower the loader arms.

to the head of the tensioning bolts as possible
(Figure 11).

Use a hoist to lift the chain.
5. Remove the boom, flip it over so the bottom
becomes the top (or if you have already flipped
it once, replace it), and install the boom again
(Figure 11).
