3. Continuing with the assembly, insert the mast into the support angles on the platform.
An axle bushing with stud and nuts for securing in place is on the platform. Carefully
remove the fiber optic cable packed into the lower end of the mast and straighten the
leads. Insert the mast between the two angle supports in approximately the correct
position. Insert the mast axle. After the axle is in place, route the fiber optic limit
cables through the fiber optic hole provided in the platform.
Do not damage the fiber optic cable during this step. Make sure it is out of the
way when inserting the mast axle through the mast.

4. Place the carrier and top cap into the position shown on the mast. Verify that the
carrier brake engages the corner of the mast and all components are oriented as
shown in the following picture. The top cap of the mast bolts into place with an axle
nut and a threaded fiberglass stud and nut combination. Securely tighten the nut and
stud to secure the top cap. The stud should be flush with the nut when tightened in
the proper position. Uncoil the guy ropes and let them hang unobstructed.
