4.28 HOSE ROUTING PROCEDURE
For proper hose routing and cable wrap placement and
clamping, refer to Figure 4-29., Figure 4-30., Figure 4-31.,
Figure 4-50., Figure 4-51., and Figure 4-52. It is important
to periodically inspect hoses, wraps and clamps for
proper slack adjustments and clamping integrity (pull
check). Any changes as a result of inspection should be
verified by performing full strokes of boom functions espe-
cially lift, telescope, jib, and platform rotate.
