side and position the door as close as possible to the door header. Be sure that the door is able to revolve without scraping against door header or guides. Rotate door assembly so that bottom bar angle is at bottom of curtain roll.

WARNING

To avoid serious injury or death, never walk, stand, or work below door assembly before it is secured to support brackets.

STEP 6 SECURE AXLE SADDLE CASTINGS

Making sure that the bottom bar angle is at the bottom of the curtain roll; place the axle saddle castings around the axle on each side, with the flat keeper plate on top. Install the 3/8-24 x 3-1/2” bolts, flat and lock washers, and 3/8-24 nuts as shown. Be certain to tighten both nuts to a torque of 40 foot-pounds. Spring tension will be lost if both axle saddles are not tightly secured.

WARNING

Axle saddles hold extreme spring tension. Loose axle saddles could result in loss of spring tension, causing door to fall, possibly producing serious injury or death.

STEP 7 PRE-TENSION THE DOOR SPRINGS

Starting with the bottom bar angle at the bottom of the curtain roll, apply two complete turns of pretension to the springs by rotating the curtain roll in the direction shown. The amount of tension required may vary slightly. Final adjustment, if necessary, will be made in Step #10.

WARNING

WARNING

WARNING

Spring tension can cause curtain roll to rotate rapidly. Securely hold curtain roll from rotating while applying pretension or serious injury or death could result.

Securely hold door curtain until bottom bar stop fasteners have been tightened. If not securely held, door may raise or drop, possibly causing injury or death.

Do not apply pretension to larger doors using ladders. Ladders may fall causing serious injury or death.

Cut the tape that holds the door in a roll and gently pull the curtain down into the guides on both sides until the bottom bar is below the bottom bar stops. Do not pry on the bottom bar stops to get bottom bar past, loosen fasteners until bottom bar angle easily clears stops. If the door has a tendency to close, secure in position using clamps. If the door has a tendency to rise, secure in position using a wood prop as shown. While the door is secured from moving, tighten the bottom bar stop fasteners on both guide assemblies.

HINT:

Tighten bottom bar stop fasteners with impact gun to prevent bolts from spinning.
