STEP 18: CHECK DOOR OPERATION
►
Cycle door by raising and lowering door to its fully closed and fully opened position.
►
Set limits of electrically operated doors at this time.
►
Evaluate spring tension. If adjustments to spring tension are required,
Proceed To Step 19
.
STEP 19: ADJUST SPRING TENSION (if required)
►
Loosen all 3/8" - 16 square head setscrews in tensioner and axle support at
both ends of door.
►
At tensioner end, place pipe wrench around end of axle so that pulling down on the
handle will rotate the axle to increase spring tension.
►
To increase spring tension, pull down on pipe wrench. The tensioner will automatically
grip the axle and hold the new tension setting.
►
To decrease spring tension, momentarily pull down on pipe wrench and then lift the
spring roll pin on the tensioner's knurled wheel. Gently let up on pipe wrench, allowing
the axle to rotate to reduce the tension. While holding the new tension, release the
tensioner's spring roll pin. The tensioner will now grip the axle and hold the new tension
setting.
►
Tighten all 3/8" - 16 square head setscrews in tensioner and axle support at
both ends of door.
►
Remove pipe wrench and operate door.
