8.8.3 Using the tongue-mounted winch, raise the tower so that the masts are
approximately two inches (5 cm) above the cradle locking pin (aa).
8.8.4 On machines using rivets*, drill out the rivets (bb) securing the five
guides (g) to the mid mast. On machines using screws, remove the
screws securing the five guides to the mid mast.
*Note: Replacement screws will be required for reassembly.
8.8.5 Pull the upper mast partially (2–6 feet (1–2 m)) out of the mid mast.
8.8.6 Make note of the upper mast cable (cc) as it passes around the mid-
mast pulley (dd) then between the mid-mast pulley and the guide
hardware (ee). Remove the mid-mast pulley. Remove the guide
hardware only if it requires replacement.
8.8.7 Remove the upper mast (k) completely from the mid mast.
8.8.8 Remove the hardware securing the cable eyebolt (p) to the main mast.
8.8.9 Remove the hardware securing the cable to the upper mast. Once free
from the upper mast, run the cable back through the opening near the
guide screw in the mid mast and remove cable completely from the
machine.
Reassembly:
Replacement cables must be of the exact length of the original
equipment. Using shorter cables may cause severe personal injury.
8.8.10 Mount the mid-mast pulley (dd). Run the upper mast cable (cc) around
the mid-mast pulley (dd) and between the pulley and the guide
hardware (ee). Attach the cable to upper mast (k).
8.8.11 Slide the upper mast into the mid mast (i).
8.8.12 Attach the five guides (g) using new self-tapping screws. Position the
guides so that the self-tapping screws thread themselves into the
smaller side of the tapered hole in the guide.
Note: Limit reuse of the guides to one time.
The guides must be installed because they serve as safety stops.
Without them properly installed, the upper mast section could be pulled
out of the mid-mast section, possibly causing severe bodily harm.
8.8.13 Secure the cable eyebolt (p) to the main mast.
8.8.14 Mount the light fixtures and reconnect the wiring.
