R4: Check for and remove obstructions to gate movement.
Troubleshooting indicates something external to the gate is obstructing movement. Inspect for
and remove excessive buildups of debris, snow, ice, etc. along both sides of the Gate, Long and
Short CMB's, and the exposed portions of the Guide Rail. Also inspect and remove any buildups
that may have occurred around the Anchor Plates, Transitions, and Drive Cable system. Check
for even clearance on both sides of Gate at transition.
R5: Check for and repair the locking linkage in the Bulkheads.
Troubleshooting indicates something may be wrong with the Locking Linkage in the Bulkhead.
Inspect the linkage for loose components. Make sure that all clevis pins are in place and
secured by retainer pins. The Hooks must fully engage the pins in the locked position and be
fully disengaged in the unlocked position. Replace damaged or excessively worn parts.
R6: Check for and repair gate structural damage.
Troubleshooting indicates the Gate has structural damage that must be replaced for proper gate
operation. Assess the degree of structural damage. Minor structural damage to a small number
of Side Panels, Panel Splices, Top Covers, etc. can be easily repaired by removing and
replacing the damaged components. Major structural damage requires full replacement.
