Pump will self-prime at low or high speeds. Make sure
that all connections are airtight. 12 Volt models are
equipped with mechanical clutch engagement
screws in case of electrical failure. To mechanically
engage clutch, loosen locking nuts, tighten allen
head screws and retighten locking nuts. Reverse pro-

engagement feature is not desired, the screws may
be removed. DO NOT RUN PUMP DRY FOR MORE
