Spring
Adjustment
NOTE: A properly counterbalanced door should remain in the same position when stopped.
If the door leaves the floor by itself, the spring is wound too tightly, and a few quarter turns
should be released. If the door tends to drop when stopped, a few more quarter turns should
be added.
NOTE: To determine the amount of turns on a newly installed spring, measure from the
bottom of the door to the header. Divide that measurement by ten and then add three. This
number is the approximate number of turns needed to wind the spring.
Turns are counted by
using the chalk marks, which show up as stripes as the spring is wound.
1. Close door and clamp counterbalance shaft from the inside with handle of locking pliers against
the ceiling to keep cables tight. Protect the roof from the pliers with a piece of plywood or sheet
metal.
2. Insert a heavy-gauge steel winding bar into one of the spring-winding plug holes.
3. Loosen setscrews on spring-winding plug.
4. Insert a winding bar that is 1/2" in diameter and 18" long into one of the spring-winding plug
holes.
5. Raise the bar to allow insertion of second winding bar into next spring-winding plug.
6. Continue to raise bar to wind spring.
7. Tighten setscrews.
8. Remove locking pliers and winding bars.
9. Cycle door to check operation.
10. Adjust again if necessary.
11. Lubricate with a light oil (Utilimaster P/N 04202540).
