5. Remove the four bolts and hardware holding the
backrest to the mast. Carefully remove the backrest;
it can be heavy - use adequate lifting apparatus or
ask for a help.
6. At the mast, disconnect the lift cylinder hose and
both side shift hoses from the hydraulic control valve.
7. Oil will drain from the cylinder lines and the hoses.
Have shop rags handy to manage spills. Plug and/or
cap the cylinder ports and hoses to prevent further oil
drainage.
8. Tag each hose for identification.
9. Attach an overhead crane and strap, rated to 3 tons,
and apply slight lift to the mast. See See Figure 3-5.
10. Disconnect the two tilt cylinders from the mast - see
“Tilt Cylinders,” beginning on page 3-20. See
Figure 3-6.
11. With the tilt cylinders disconnected from the mast,
move the overhead crane forward slightly to provide
a gap between the mast and the front mounting plate.
See Figure 3-6.

18. Before returning the mast to service, perform all
adjustment procedures listed in enclosed supplier
provided information in Chapter 7.
