READ YOUR ENGINE MANUAL!
Before proceeding further, locate and read the engine
manufacturer’s manual. It contains very important safety
information that MUST be read, understood and followed to
safeguard you and your equipment from harm, as well as for

READ THE PUMP OWNER’S MANUAL!
The improper use of this pump could result in serious injuries
as well as damage to the unit. Read the BB-
4 Owner’s
Manual before using your BB-4 pump unit and follow the
safety instructions in this Quick Guide.
NEVER RUN THE ENGINE IN A CLOSED

carbon monoxide which is poisonous to humans.
Avoid inhalation of exhaust gas.
REFUEL ENGINE WITH CARE. Gasoline is
extremely flammable, and gasoline vapor can
explode. Refuel in a well-ventilated area, with the
engine stopped.
NEVER TOUCH ANY EXHAUST SYSTEM
PARTS WHILE ENGINE IS RUNNING. Always
allow enough time, after stopping the unit, for proper
cooling of the muffler and surrounding parts.
EQUIPMENT DAMAGE PREVENTION:
Flush the pump with fresh water if the pump has been
used to pump salty, brackish, high mineral content
water, water containing debris, or foam injected water.
Check that debris is cleared before using the pump
again.
Always draft water using a suction hose strainer.
