Turning Handles
Turning handles ship with rotatable base plates to assist in rotating the mast. Note that rotating
Super Heavy Duty masts do not use turning handles.
To secure the turning handles:
1. Determine the desired location for the turning handles. If feasible, The Will-Burt Company
recommends installing above the drain hole. Do not cover drain hole with the turning handles.
2. Secure the band clamp halves together around the mast with:
• (2) ¼-20x1.50 Hex HD Bolts (P/N: 2000)
• (2) ¼-20 Nyloc Nuts (P/N: 1930)
Tighten the turning handle bolts just enough to allow the turning handles to turn the mast
without slipping. Overtightening the turning handle bolts can deform the base tube and
impede the movement of the next internal section.
For masts with:
• Ø 5.00 Inch Base Tube: Torque to 60 in.-lb. (6.8 Nm) Maximum
• Ø 6.75 Inch Base Tube: Torque to 100 in.-lb. (11.3 Nm) Maximum
• Ø 9.00 Inch Base Tube: Torque to 120 in.-lb. (13.6 Nm) Maximum
The mounting hardware must include proper means to resist vibration loosening such as
thread-locking compound or locking hardware.
Once the mast is installed, see Section 5.8 for information on installing the pneumatic system.
