2.14 FINAL ADJUSTMENT
1. If the door is hard to operate in
ANY DIRECTION check that the
door is not jamming in the guides.
Check: a) the guide clearances;
b) that guides are plumb;
c) that the guide surfaces are clean and free from oil;
d) that locking bars are the correct length; and
e) that weatherseal is correct length.
2. If the door is hard to operate in
ONE DIRECTION, the spring
tension requires adjustment. See 2.11.
a) If the door is hard to lift, but tends to drop, then
increase the spring tension.
b) If the door is hard to close, but tends to rise, then
decrease the spring tension.
3. If the door rolls up crooked as shown right then:
Check: a) Brackets are level, refer to Step 2.2.
b) Axle is centralised.
c) Guides are plumb, refer to Step 2.9.
To centralise the axle - NOTE: these instructions are for the example illustrated - the axle needs moving to the right (to move left they
would be vice versa).
NOTE: Springs are tensioned and can cause injury.
With the door rolled up tie two ropes around the door roll approximately 300mm from each end, as a safety precaution. With the door
rolled up, loosen one “U” bolt, then go to the other end of the door and with a firm hold on the axle, with a pipe wrench, loosen the
second “U” bolt and move the axle to the right (the direction of the arrow in diagram ). Move the door distance “X” in diagram.
Re-tighten one of the “U” bolts before releasing pipe wrench then re-tighten the other “U” bolt.
If the door is stiff to work or rattles over lead-in on top of guide, then refer to Step 2.4.

1. With the door rolled up tie two ropes around the door roll
approximately 300mm from each end, as a safety precaution.
2. With a person at each end of the door, hold the axle firmly
with a large pipe wrench (Stillson) at least 450mm long.
3. Loosen the “U” bolt nuts at both ends and
KEEP A FIRM
GRIP ON WRENCH.
4. Rotate the axle in the required direction (see diagram).
5. Re-tighten the “U” bolts
BEFORE releasing pipe wrench.
6. Test and repeat if further adjustment is necessary.
