2.5 SPRING TENSIONING BOTTOM RAIL STOPS
Check top of guide lead in to ensure that the door does not make contact when rotated. Damage to nylon running strips could result.
The curtain must feed in smoothly without bumping – adjust lead in as required.
Apply, tension to the springs by rotating door approximately two (2) complete turns in a forward direction (see arrow on sketch A)
after ensuring axle is securely clamped. The amount of tension required for satisfactory operation may vary with individual doors,
depending on size. Final adjustment should be made later.

WARNING
Once the packaging containing the door roll is cut, the door will have
a strong tendency to rise and revolve. If uncontrolled, the rapidly
unrolling door could cause damage or injury. Therefore, it must be
securely held until bottom rail stops are fi tted. Chain wheel doors can
be held in position by locking the chain in the chain clip attached to
the left hand guide.
Hold door fi rmly and cut the packaging. Feed door down into guides
below head stop.
Fit bottom rail stops using self locking nuts provided. Allow door to
rise and to rest against head stops. (See sketch B.)
FINAL ADJUSTMENT
Operate door up and down a number of times to check operation.
If operation is uneven or not smooth, rectify as below: –
Faults
1. Door hard to operate in one direction.
2. Door hard to operate in both directions.
3. Door is stiff to work and rattles over lead in on top of guides.
4. Door is scraping in the guides.
WARNING
Do not grease the guides. Grease will damage the nylon running strips and make doors heavier to operate.
Remedies
1. Adjust spring tension.
2. Check guide clearances (see that door is not jamming). Also check that the inside surfaces of the guides
are clean and free of any oil fi lm. Use a spirit cleaner if necessary. Polishing the inside surfaces of the
guides improves operation.
3. i) Check that guides are not too long. Move the door closer to the lintel.
ii)
With the door up and chain secured, loosen one “U” bolt/saddle bolt and push that side of the door
towards opening as far as possible without scraping lintel. Tighten the “U” bolt and repeat operation
with the other side, ensuring that the axle is still parallel with opening.
iii) Pack out top lug of guide.
4. Check that the guides are plumb, the clearances are correct and the door is correctly centred with the
opening. Also check that the brackets are level.
