Step 7 : Install mechanical roll up doors
Front and rear door installation - when you look at figure 12, please look at
the door from inside.
Components include: one hand winch (#23) and steel cables (#23A). The hand
winch comes with a shorter cable, we call it cable (#B).
Mount the hand winch on the lower beam (#13).
Slide the bottom dropping tube (#15,#16) into the bottom horizontal fabric
pocket on door cover (#35). Then slide the other six upper dropping tubes
(#15, #16) into other horizontal pockets.
From the bottom door rails (#10L,#10R), slowly put the first dropping tube
(#15, #16) into the rail, then put the others (#15, #16) into the door rails.
Pull cable( #B) from the winch to run through the lower roller of the dual
pulley (#23B), go straight down at the left side, reach to the left end of
dropping tube (#15). Tie the cable to the end hole.
Connect cable (#23A) to the winch and pull it to run through the upper roller
of the dual pulley (#23B), reach through the single pulley (#23C), then go
straight down to the right end of dropping tube (#16). Tie the cable to the end
hole.
Now the door can be opened or closed by operating the winch assembly. Run
the door up and down a few times to make sure all dropping tubes are moving
smooth. Use lubricant oil if needed.
