cylinders (5) (Figure 5-13) and carefully lower the
counterweight (1) (Figure 5-13) onto the counterweight
supports.

(Figure 5-13) and carefully lower the auxiliary hoist
structure (7) (Figure 5-14) onto the counterweight.

Do not attempt to separate the auxiliary hoist structure (7)
(Figure 5-14) from the counterweight (1) (Figure 5-13)
while on the counterweight stand (1) (Figure 5-12). The
auxiliary hoist structure (7) (Figure 5-14) may hit the
