Troubleshooting If stair section is jumping out of track Check width of stairs. Measure the outside to outside ladder width at the backside. Compare this to the dimensions in the installation instructions for your particular stair. Check dimension between slide bars as compared to dimensions in installation instructions. Call the factory if there is a difference by more than 1/8". If stair section is hard to move or binding Make sure slide bars are in the guide channel over the entire length of travel. Lubricate guide channel with Vaseline. Check the ladder width at the backside of the ladder. It should not be more than 1/16" out of specification. If not within spec., refer to installation instructions on ladder assembly. The factory is available to further discuss the problem. If cable runs off of drum when moving stair section Check to see if stair is centered in opening. Check for proper alignment of hardware. Check for alignment and plumbness of jamb. Mounting brackets can be shimmed to correct minor misalignment. If stair section comes down too fast Add spring tension to stringer drum. (See Instruction Manual for more help) If stair section "creeps up" from down position Reduce spring tension to stringer drum. (See Instruction Manual for more help) If Door Panel fails to close Add spring tension to panel drum. (See Instruction Manual for more help) Make sure screw heads are seated against hinge. Check for foreign debris. Check for ladder hitting something in attic. Check clearance in attic for ladder to go all the way to its resting position. If Door Panel slams shut Reduce spring tension to panel drum. (See Instruction Manual for more help) If you break or back-wind a spring CALL THE FACTORY. WARNING: The spring inside the drum, even though broken or back-wound, is under EXTREME compression. DO NOT OPEN THE SPRING DRUM. Call the factory for instructions before returning for repairs
