Step 1.
Slide shuttle assembly onto tube (one piece only) and
locate it in approximately half way position.
PLEASE NOTE:
Arrow on shuttle must point towards
garage door. To assemble the rest of the tubes, always
slide short insert tube half way into the long tube, then
slide other tube onto remaining portion of insert tubes.
Continue this process with remaining tube until desired
length is achieved.
Step 2.
The opener is supplied with an 8 teeth drive sprocket
on the drive unit. If the opener is to be fitted to a
one piece door without track, exchange the 8 teeth
sprocket on drive unit, with a 7 teeth drive sprocket
available as an option from Automatic Technology.
Step 3.
Attach one end of chain to chain index screw, nearer
to drive unit, using one joint link. (Fig. 1). Proceed
to wrap chain around drive unit sprocket and chain
spreader, then follow along the pipe to the idler wheel
on support pipe assembly, finally attach to the other
end of the chain index screw.
NOTE:
Make certain that the teeth of the drive
sprocket are engaged in the chain and that the chain is
not twisted. Make sure that the chain is engaged in the
chain spreader and the idle wheel on the support pipe
assembly.
Step 4.
Disengage trolley from chain index by swinging lever
downward (Fig. 2), then slide trolley away from chain
index along pipe track. Loosen locking nuts on chain
index screws. To tighten chain, turn chain index in
anticlockwise direction, looking from support pipe
assembly to drive unit. Do not over-tighten chain as
it has to sag 6-12mm. Check before locking screw
with locking nuts that chain is not twisted. When the
tension is finalized, tighten lock nuts at both ends of
chain index.
