QUICK GUIDE
To operate the BB-4-D902 unit:
1. Supply recommended diesel fuel grade to engine. Do not
mix gasoline or alcohol with diesel fuel. If using a fuel line,
connect the line according to the engine manufacturer’s
instructions.

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
discharge valves so that the unit may be started.
3. Connect discharge hose, nozzles, etc., to pump, and tighten
firmly with coupling wrench.
!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.
4. Activate the control panel. If you are using the Panel Mount Standard
Control Panel (PMSCP-DIESEL), push the control panel’s ON/OFF button.
A green ring on the button will light up indicating that the panel is powered.
5. 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: If your pump is equipped with a WATERAX electric
primer, move the PRIMER toggle switch on your control panel to the up
position and hold it in place to allow water to enter the pump. The electric
primer is intended to be used only a short duration (about 20 seconds). If
pump fails to prime, see the BB-4 Owner’s Manualfor troubleshooting tips.
Close the priming ball 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.

6. Start the engine.
a. Warm up: The electric starter’s glow plugs require a 10-second warm-
up period which begins as soon as you push the ON/OFF button on
the control panel. During the warm-up period, the START button is
deactivated and the engine cannot be started. As soon as the warm-
up period is over, the low oil pressure ( ) light will turn on,
indicating that the engine is ready to start.
b. Make sure all discharge valves are closed.
c. Push and hold the START button on the control panel until the engine
engages.
d. Turn the Vernier throttle counter-clockwise to increase engine speed
past the idle position. Pressure should build up in the system.

7. Discharge water.
Once the pump is primed, and with the engine running, you can begin to
discharge water.
a. Slowly open the discharge valve. 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.
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.
c. Press the LOW PRESSURE PROTECTION button to activate the
protection. If pressure drops below 7 psi (loss of prime condition), the
engine will automatically shut down to protect the pump.
!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.

QUICK GUIDE
To shut down and store the BB-4-D902 unit:
1. Shut down the pump.
a. Gradually reduce the engine speed.
b. Whenever the unit has been run at full throttle for most of the operation, allow the valves to remain slightly
open and run the engine at idle for approximately 5 minutes before shutting down the unit.
c. Turn off engine.
d. Close off the hydrant/supply to the pump.
e. Open all valves to relieve any pressure left in the system.
2. Check and store the pump.
a. If the pump was last run with foam or water that is salty, brackish or high in mineral content, flush the pump
with fresh water for a minimum of 2 minutes or until water is clear.
b. After the unit has cooled down, check all fluid levels and add as needed.
c. Completely drain the pump of all water.
d. Break down and store all equipment as outlined by the apparatus or department procedures.
e. Visually inspect the pump end. Clean any dirt or debris from the pump unit. If necessary, a mild soap and
water solution can be used. Note and report any performance irregularities or any abnormal mechanical
sounds.
f. Close all valves and plug all openings.
g. Follow any other product, component, apparatus, and departmental procedures and/or guidelines before
placing the unit in storage. Make sure all necessary tools, spares, and accessories are with the pump.
To operate the BB-4-D902 unit in cold weather:
The pump can be run in below freezing temperatures if certain precautions are taken to avoid the formation of
ice in the pump.
After priming the pump, the unit should be run at low speed for a short period of time to allow all components
to warm up before continuing with the remaining operating procedures.
Unless wrapped in a heater, drain the pump of all water if it is stopped for any length of time. The engine/drive
unit should be turned over a few revolutions to make sure all water has been removed from the pump. Drain
the pump priming line if a primer has been used.
After use, drain the pump, manifolds, and lines of all water. You can also pour some RV antifreeze into the
pump and circulate it through the pump and plumbing system.
