STEP 8
INSTALL SLIDE BOLT LOCKS
Install slide bolt locks, if provided,
as shown.
Install the lift handle to bottom bar
angle at this time.
STEP 9
LUBRICATE AND ADJUST THE GUIDES
Lubricate the insides of the guides and wearstrips with weather resistant lubricating spray. Be sure to spray lubricant
over the flares at the tops of the guides. Move the door up and down to check for proper operation. Adjust the guides
and mounting angles if necessary to allow for proper clearance and operation.
If door is difficult to move up and/or down due to spring imbalance,
continue on to step #10 and return to step #9 once springs are properly
adjusted.
STEP 10
CHECK AND ADJUST SPRING BALANCE
It is strongly recommended that two or more installers perform
this next step.
Never remove bottom bar stops when adjusting tension,
otherwise, door can spin uncontrollably resulting in serious
injury or death.
If the door lowers easily and raises hard, more spring tension is required. If the door lowers hard and raises easily,
less spring tension is required. Before adjusting the spring tension, be sure that the door is in the full up position.
Secure the door in the full up position to prevent the door from falling if the adjustment wrench slips. Use one of
these methods:
• Tie a rope around the door roll and bottom bar angle.
• Place a clamp on guides holding the door securely at the stops.
Always stand to one side of wrench when adjusting tension.
Never adjust tension with wrench in front of/above you. This
will help avoid serious injury if you lose control of wrench.
