NOTE:
To prevent damage to the end panels,
do
not allow the free end of the axle to touch the inside
surface of the end wall. Trim pipe if needed. Axle must
turn freely.
18. After installing all sections of axle conduit for the first
drop-down curtain assembly, verify that the axle conduit
is level and that each conduit splice is secured with a
Tek screw (Step 14).
19. Move to the gearbox and test the assembly using the
crank handle.
NOTE:
The assembled axle conduit should turn freely
throughout the length of the shelter. Adjust the band
clamps as needed. Reposition clamps and screws if
these prevent smooth operation of the axle conduit.
20. After verifying that the axle turns smoothly, repeat the
procedure to assemble and attach the gearbox and
axle conduit
to the other side of the shelter.
21. Continue by preparing and attaching the drop-down
curtains to the frame and axle conduit of both drop-
down assemblies.

Continue with the steps that follow:
1. Gather the pulleys and the same quantity of 3" eye
screws (FA1960) and move to the inside of the shelter.
2. Slide one pulley onto the threaded shaft of the eye
screw and twist the eye screw into the ribbon board
4"-6" on either side of the first rafter to secure the
pulley.
NOTE:
Position the eye screw and pulley 4-6 inches
away from the rafter on either side of the rafter.
Pulley should hang freely from the eye screw.
Do not
overtighten the screw.
3. Move to the next rafter and repeat the steps to install
another pulley.
Install one pulley for each rafter along
each side of the frame.
4. Continue installing eye screws and pulleys into the
ribbon board
next to each rafter
until all pulleys are
installed
along both sides of the shelter
.
