STEP 7 PRE-TENSIONING THE DOOR SPRING
WARNING
Spring tension can cause curtain assembly to rotate rapidly, possibly resulting in severe or fatal injury. To prevent such injury, securely hold curtain assembly to prevent rotating.
Starting with the bottom bar at the top of the curtain roll, apply two complete turns of
Cut the tape that holds the curtain 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 the stops. Instead, loosen fasteners until bottom bar angle easily clears stops. If the door has a tendency to close, secure it in position using clamps. If the door has a tendency to rise, secure it in position using a wood prop.
WARNING
Securely hold curtain assembly until bottom bar stop fasteners have been tightened. If not securely held, curtain could rotate, possibly causing severe or fatal injury.
With the door kept from moving, tighten the bottom bar stop fasteners on both guides. Remove clamps or wood props.
STEP 8 LUBRICATING AND ADJUSTING THE GUIDES
Lubricate the insides of guides with weather resistant lubricating spray. Move the door up and down to check for proper operation. Adjust the guides if necessary to allow for proper clearance and operation.
HINT:
If door is difficult to move up or down due to spring imbalance, continue on to STEP #9 and return to STEP #8 once springs are properly adjusted.
