WARNING:
Ensure pipe wrench is fitted correctly to axle and it is gripped onto the axle. Do not
underestimate the tension in the spring when undoing the clamps.
CAUTION:
This adjustment requires two persons to perform.
If the door rolls up crooked with one side than the other, proceed as follows:
• Roll the door up as high as possible and tie two ropes around the door roll approximately 300mm from
each end, as a safety precaution.
• With a person at each end of the door, hold the axle firmly with a large pipe wrench (Stillson) at least
450mm long.
• Loosen the “U” bolt nuts at both ends and KEEP A FIRM GRIP ON WRENCH.
• Move the axle to the RIGHT between 20 - 40mm.
• Re-tighten “U” bolts before releasing pipe wrench.
• Test and repeat if further adjustment in needed.
• If the door is stiff to work or rattles over lead-in on top of guide, then refer to page 36.
