QUICK GUIDE
B2X-21
This Quick Guide shows the basic operation of the WATERAX B2X-21 2-stage mid-range pump.
• The WATERAX B2X-21 pairs a WATERAX 4-stage pump end with a Honda GX630 gasoline engine. For
instructions regarding the engine, as well as for oil and fuel recommendations, please refer to the engine
manufacturer’s manual.
• For detailed instructions on using and troubleshooting your pump, as well as full service and maintenance
instructions, refer to our website to download the B2X Owner’s Manual.
• For full specifications and performance curves, see the B2X-21 Data Sheet.
Warnings and Safety Precautions
This warning label appears on all WATERAXpumps to identify safety
hazards as follows:
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
the proper use and care of your engine. Use only fuel and
oil type recommended in the engine manufacturer’s manual.
Always check oil level in crankcase before use.
WEAR EAR AND EYE PROTECTION.
Always wear eye and ear protection when operating the
pump unit. Sound level of the unit: 92 dB(A).
GENERAL WARNINGS:
•Do not operate if mentally or physically fatigued.
•Inspect hoses and piping to avoid burst injuries.
•No modifications and/or alterations may be made to the
pump. Any such modifications void the pump warranty
and can endanger pump operators.
•Do not operate the pump above the maximum rated
pressure. Use only pipe, hose, and fittings rated at or
above the maximum pressure rating of the pump or
system design.
•Slowly close valves. Use slow close valves wherever
possible to safeguard operators and prevent damage
from water hammer.
•Dry weight of the unit: 169 lbs (will vary depending on
options).

QUICK GUIDE
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 B2X Owner’s
Manualbefore using your B2X pump unit and follow the
safety instructions in this Quick Guide.
NEVER RUN THE ENGINE IN A CLOSED
OR CONFINED AREA.Exhaust gas contains
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 these parts and surrounding areas.
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.

QUICK GUIDE
To operate the B2X-21 unit:
1. Fill fuel tank with recommended fuel grade and securely
replace cap. Check oil (see engine manual).
Suction/
Intake Port
Discharge Port
2. Connect the suction hose, using a universal hose coupling
wrench to tighten coupling firmly:
Drafting Mode: Connect the strainer or footvalve strainer to the
male end of the suction hose and then connect the female end
to the pump intake. NOTE: If desired, a suction hose with a
footvalve may be filled at this time to shorten pump priming.
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 discharge
and/or drain valves so that the unit may be started.
!!DO NOT allow the 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).
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 B2X
Owner’s Manualfor troubleshooting tips.
Priming port
!! 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.

QUICK GUIDE
5. Start the engine.
a. Close/engage choke, if engine is cold.
b. Increase throttle past the idle position.
c. Position the ignition switch to the ON position.
d. Turn the engine switch to START position until the engine starts. DO NOT hold for more than 5 seconds.
e. Open/disengage choke.
f. Allow the engine to warm up for at least 2 minutes before using full throttle.
6. 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.

QUICK GUIDE
To shut down and store the B2X-21 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 the 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 the 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 B2X-21 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 antifreeze into the pump
and circulate it through the pump and plumbing system.
