6. Raise shaft slowly, tucking blades into shaft while
shaft and blade assembly is being inserted into tube.
NOTE:
If lift binds, STOP and back off hydraulic
pressure. Check that blades have not swung fully out and
are not binding on the edge of alignment tool. If this
happens, check blades and replace as necessary. Restart
lift, taking care to guide blades into alignment tool.
7. If blade aligning tool is not used, the individual
controlling hydraulic lift should use one hand to guide
each pair of blades into tube.
8. As shaft is raised into gear reducer, it may be
necessary to rotate shaft slightly to assure splines are
meshed correctly.
9. Continue to raise shaft until head is about six (6)
inches from being engaged.
10. Once the last set of blades has been started in tube,
remove alignment tool, if used.
11. Continue to raise head slowly, aligning teeth of head
with spaces of tube. Raise and turn head so teeth are
engaged and product port is facing forward.
12. Close locking latch. See Figure 42.
13. Install product piping and electrical connections.
