distance between the edge of the door curtain and the

The door must be well balanced and be in a
reasonable operating condition. You should be able
to lift the door smoothly and with little resistance. It
should stay open around 900mm to 1200mm above
the fl oor. The door should not stick or bind in the
guide tracks. The ideal operational effort in raising
or lowering the door should not exceed a force of
10kg (22lb). Make sure that all door locks, ropes,
chains etc. are either released or disabled and remove
unnecessary accessories.
2. Fixing Of Door Weight Bar
Move the door manually to the half open position.
Place the weight bar on the bottom rail in the middle
of the door and secure with the fasteners provided
(Fig. 02).
Check the operation of the door again. If
the door feels heavy it may require extra tension to
be added to the door springs.
IMPORTANT - Door
springs are under extreme tension and should only
be adjusted by a garage door professional.
3. Installing Locking Bar Covers
To protect against entrapment of fi ngers etc. inserted
into door guides – remove the protective backing of
the double sided tape and install the locking bar covers
over the holes in each door guide.
