Vacuum pump is running more often than normal. Likely
causes include significant vacuum leak or difficulty
achieving minimum vacuum level due to high elevation.
In case of suspected leak, check for fault(s) in vacuum
system. See relevant topics in “ASSEMBLY,” “OPERATION”
“INSPECTIONS AND TESTS”, and “MAINTENANCE”.
In case of high elevation, contact WPG for directions.
