QUICK GUIDE
To operate the BB-4-18/23 unit:
1. Fill fuel tank with recommended fuel grade.
a. For models with an integral fuel tank, fill tank and securely
replace cap.
b. For models without an integral fuel tank, fill external fuel tank
and connect fuel supply line to the fuel filter. Pump fuel to fill
supply line.
Check oil level (see engine manual).

2. Connect the suction hose
, using a universal hose coupling
wrench to tighten coupling firmly:
Drafting Mode
: Connect footvalve strainer to male end of suction
hose, then fill suction hose with water and connect to pump
intake.
Flooded Suction Mode
: Connect female end of suction hose to
pump intake and connect male end to hydrant or other supply.
a. Slowly open the pump inlet valves allowing the water into the
pump body.
b. Slowly open the discharge valves and priming valves to
allow for entrapped air in the piping to escape.
c. Once all the air has escaped, slowly close any opened
valves so that the unit may be started.
!
DO NOT
allow footvalve strainer to rest on
bottom of lake or riverbed. Check strainer
frequently to make sure that it is not clogged
with moss, leaves, etc.
!
DO NOT
lift strainer from water while the pump
is operating. Use a rope or other means to keep
strainer at proper height, approximately 1 foot
(30 cm) below water surface. If strainer is too
close to the water surface, it will draw air and
pump may lose prime.
3. Connect discharge hose, nozzles, etc., to pump
, and tighten
firmly with coupling wrench.
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 pump’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.
