4. Prime the pump.
Check that all drains, discharge valves, or any auxiliary valves are closed
before priming the pump. Open the priming ball valve (located between the
pump and the primer).
Manual Priming: Open the priming cap and fill pump with water manually.
Firmly tighten priming cap. Pump can also be primed by “jerking” the suction
hose until water flows from the pum
p’s discharge port.
Guzzler Priming: If equipped with a Guzzler primer, follow the hand pump
manufacturer’s operation instructions. Pump until water is drawn into the
pump.
Electric Priming: See instructions for your electric primer. Note that most
electric primer motors are intended to be used only a short duration (about 20
seconds). If pump fails to prime, see the BB-4
Owner’s Manual for
troubleshooting tips.
Close the priming valve after priming. Failure to close the priming valve
could cause the pump to lose prime or water to be pumped through the
priming system.
Exhaust Priming: See Step 6.
Option 1:
Open priming
cap and fill
pump with
water.
Option 2:
Attach hand primer to
discharge port and
pump until water flows
into pump-end.
Option 3: Use
guzzler or exhaust
primer (not shown),
if equipped.
5. Start the engine.
a. With all discharge valves closed, turn the on/off ignition key or switch (if
equipped with a Control Panel) to the
“ON” position.
b. Open fuel valve.
c. Close/engage choke, if engine is cold.
d. Increase throttle past the idle position.
e. Start the engine using the key switch or the start button. Hold until
engine starts. DO NOT HOLD for more than 5 seconds. If starting using
the rewind starter, ensure that the key switch or ignition switch (if
equipped with a Control Panel) is on the "ON" position. Give starter rope
a quick steady pull until engine starts.
f.
Open/disengage choke.
g. Allow the engine to warm up for at least 2 minutes before using full
throttle.

6. Engage the exhaust primer.
a. Open priming valve (located just below check valve on portable units).
b. Adjust THROTTLE to full speed position.
c. Close and press down firmly on muffler-lever-handle or pull priming knob
(if supplied with a panel mount control panel) until a solid stream of
water flows from priming ejector.
d. Close the priming valve and re-open the muffler-lever-handle/butterfly
valve. The check valve will open automatically under the water pressure
when priming occurs.
e. Slowly open a discharge valve to validate that the pump has been
primed. If pressure does not build in the discharge hose, the pump has
not been fully primed. The valve should be closed and the pump primed
again. Continue this process until the pump has been fully primed.
f.
Reduce throttle setting and allow engine to warm up for at least 2
minutes before using full throttle.
Exhaust Primer (optional)
7. Discharge water.
Once the pump is primed, and with the engine running, you can begin to
discharge water.
a. If pressure does not build in the discharge hose, the pump has not been
fully primed. The discharge valve should be closed and the pump primed
again.
b. Adjust the pump performance by throttling the engine up or down, or
opening or closing discharge valves at various positions, or any
combination of the two.
! DO NOT leave the pump running
with all the discharge valves closed for
more than one minute, or else the
pump may overheat and become
damaged. To avoid this, a re-
circulation line (if provided) should be
opened or a discharge line left slightly
open to allow fresh water to continue
to enter the pump.
