Attach the Base Plate to the Mast
This section describes installing the mast and base plate. The exact procedures vary depending
on whether the mast system uses a non-rotatable or rotatable base plate. Follow the appropriate
installation instructions for your mast system.
Non-Rotatable Base Plates
To install a non-rotatable base plate:
1. If necessary, use a hoist to lift the mast so the bottom of the mast can be accessed.
2. Position the base plate against the base of the mast so the mounting holes align. Ensure the
countersunk holes are facing away from the mast.
3. Heavy Duty and Super Heavy Duty: Secure the base plate to the mast with the (4) ⅜-16x1
flathead screws (P/N: 2772) from the hardware bag. Apply Loctite
®
242/243 (Blue) or
equivalent. Torque to 15.83-20 ft.-lb. (21-27 Nm).
Ultra Heavy Duty: Secure the base plate to the mast with the (4) ½-13x1.25 flathead screws
(P/N: 5402) from the hardware bag. Apply Loctite
®
242/243 (Blue) or equivalent. Torque to
37.5-43.33 ft.-lb. (51-59 Nm).
Rotatable Base Plates
To install a rotatable base plate:
1. If necessary, use a hoist to lift the mast so the bottom of the mast can be accessed.
2. Back the locking screws far enough out of the base plate to allow the base plate to fit over the
end of the mast.
3. Slide the base plate over end of the mast.
4. Tighten down the locking screws to secure the base plate to the mast.
