METHOD OF FITTING OPTIONAL
PADBOLT TYPE LOCKING
CENTRE LIFT LOCK
a.
Undo screws to separate lock from faceplate.
b. Fit faceplate to outside of door. Fit hooks onto curtain edge,
then slide faceplate as far to the right as possible. Use
adhesive tape to hold in position.
c.
Attach the lock body to the faceplate from the inside, using the
mounting screws and washers. Do not over-tighten the screws.
d. With the door in the closed position make the lock hole
position in the side guides.
e.
Drill and fi le out a rectangular slot on longer than 25mm and
no wider than 10mm. Ensure top of the slot remains in line
with top of locking bar.
f.
Slide bars through guide slot, then back, onto lock arms.
Screw on securely using 4mm x 6mm screws supplied.
g.
Fitting the lock hole cover requires the surface to be clean
and dry. Peel the lining from the lock hole cover and position
over the hole taking care that the movement of the lock bar is
not impaired.
WARNING:
Hold Axle before loosening “U” bolts.
IMPORTANT:
Do not attempt to loosen “U” bolts before securing
fi rm hold on Axle with Pipe Wrench (stillsons). Do not use fi lters
or similar brittle steel tools such as Tommy Bars.
Doors with Planetary Geared Chain Wheel Only
If the door tension needs adjusting and the door is fi tted with
Planetary Gearing then follow the steps below:
1. Ensure that the door is in the OPEN position
2. Secure a rope around the centre of the door roll and use vice
grips to clamp the guides just under the bottom rail of the
door to prevent the door from closing suddenly during the re-
tensioning process.
3. Secure both chains in the chain clip.
4. Carefully loosen the axle clamps
5. Adjusting Tension
a. To increase spring tension, carefully pull down on the rear
chain, Lock the chain in the chain clip.
b. To reduce spring tension, hold the rear chain fi rmly,
carefully release chain from the chain clips and allow the
rear chain to move upwards, take care that the full tension
is not removed from the springs. Lock the chain in the
chain clip.
NOTE:
As a safety precaution to protect both the door and the
installer, lock a section of the chain in the chain clip so that the
chain is restricted to short movements.
6. When the tension is correct, secure the chain in the chain clip
and re-tighten the axle clamps to the correct tension.
7. The correct adjustment will only be found by trial and error,
adjustments should be restricted to approximately one
revolution of the chain wheel.

SELF ADHESIVE LOCK BAR RETAINERS
Position as indicated and clean the surface before proceeding.
1. Peel back and stick in position.
2. For additional strength drill 2 x
1
/
8
holes from inside using
retainer as a template.
3. Fit 2 x
1
/
8
pop rivets to each retainer from the face of the door.
ADJUSTING SPRING TENSION IF NECESSARY
Hand Operated and Direct Drive Doors Only
With door in open position (rolled up), tie two ropes right around
door approximately 12” from each end. With a person at each
end secure a fi rm hold on axle with stilson or pipe wrench and
loosen axle clamp with socket spanner. Axle can then be rotated
in required direction (see diagram below) until approximate
tension is gained. It is recommended that alteration to spring
adjustment be only by small degrees till the best position Is
found. Axle clamps must then be re-tightened to a tension of 40
Newton metres or 30 ft.lbs. Before releasing hold on pipe wrench
(stilson). Repeat process if spring still requires further tension.
