Shortening The Track - Smart Openers Smart Lifter Installation Manual

Installation
1). Read the instructions carefully.
2) Make sure the door structure is solid and suitable to
be motor driven.
3) Make sure that when the door is moving there are no
friction points.
4) The door must be properly balanced and must be
easily lowered and raised by hand.
5) Install a 240V, adequately protected 3-pin socket near
where the Smart Lifter opener is going to be installed
CHAIN SHUTTLE ASSEMBLY
For ease of installation the Smart Lifter is delivered with
the chain and chain index already assembled in the track.
If you need to assemble it yourself connect the chain
index to the chain refer (Fig. 3). Tighten screw (C) (Fig. 4
B) until the chain is reasonably tight. Do not over tighten,
but do not leave it too slack.

SHORTENING THE TRACK

The track is designed to be cut to size only if and when
required. This should only be done when space is at
a premium due to a lintel or some other obstruction.
Cut the track down to the desired size from the bracket
end only (not from the power head end). Remove the
appropriate amount of chain links with a chain breaker.
Reinstall chain in track and connect chain index as per
(Fig. 3) above. Tighten screw (c) (Fig. 4b) until the chain
is reasonably tight. Do not overtighten but do not leave it
too slack.
