TRIPOD STAND FOR NH MASTS
Fitting instructions
Before the tripod stand can be used, the top bearing must be fitted to the mast as
follows:
(1) The top locking collar must be securely clamped in position at 728mm from the
base of the mast, as shown in the sketch.
(2) Remove inlet valve so that the upper bearing can now slide up to meet the top
locking collar, ensuring that the Teflon rings are in position.
(3) The lower locking collar can now be clamped below the bearing but leaving
sufficient clearance to allow the bearing to rotate.
Once the upper bearing is fitted it can remain as a permanent fixture on the mast,
even when the tripod stand is not used.
