## Narrative

After the Silver Shaft Hoist was idle for a lengthy time the weight brake would not lift fast enough or high enough to release.  A consultant was called in to help diagnose the problem and identified that the brake set regulator pressure was not high enough to engage the brake boost solenoid.  The regulator pressure was turned up correcting the problem.
