Lower Mast Through The Internal Mounting Kit; Attach The Base Plate To The Mast - Will Burt 7-30 HDL Operating Instructions Manual

PNEUMATIC MAST WITH REMOTE LOCKING SYSTEM
OPERATING INSTRUCTIONS
e. For non-rotatable mast systems, slide the retaining ring and o-ring over the bottom of the
base tube and up the mast past the drain hole towards the collar. If they are difficult to
maneuver, put soapy water on the mast to allow them to slide more freely. Ensure the o-
ring is below the retaining ring. Temporarily secure the retaining ring and o-ring in place so
they cannot slide down the mast during transportation.
For rotatable mast systems, no actions are required at this time for the flashing kit. The
flashing kit will be installed in Section 5.7.2.7.

Lower Mast through the Internal Mounting Kit

To lower the mast through the internal mounting kit:
1. Use a hoist to slowly lift the mast above the roof. Do NOT apply pressure to the air cylinders
when lifting. Lifting with weight on the air cylinders could damage the mast. One possible
means of lifting the mast would be to secure the hold down leashes to lugs on opposite sides
of the base tube collar and connect the hold down leashes to the hoist. Depending on the
environment and equipment available, other methods may work better. Use the best and
safest method for your circumstances.
2. Align the base of the mast with the center hole of the internal mounting kit.
3. Carefully lower the mast partially though the roof. The mast should be held securely in
position partially through the roof so that the installer has safe access to the base of the mast
to install the base plate.
5.7.2.4

Attach the Base Plate to the Mast

The mast may use either a non-rotatable or rotatable base plate. Follow the appropriate
installation instructions for your mast system. When installing the base plate to the base of the
mast, ensure the mast is securely held in position.
Non-Rotatable Base Plates
To install a non-rotatable base plate:
1. 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.
2. Secure the base plate to the mast with the (4) ⅜-16x1 flathead screws (P/N: 2772) from the
hardware bag. Apply Loctite
