Schedule
Establish a preventive maintenance schedule
based on the pump's service history. Scheduled
maintenance is especially important to prevent spills
or leakage due to diaphragm failure. A clogged
muffler may restrict pump performance. Inspect
air lines and muffler media regularly to maintain
performance.
