STEP 7 PRE-TENSIONING THE DOOR SPRING
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 pre-tension to the spring 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 #9.
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.
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.
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.
