QUICK GUIDE
2. Connect the suction hose
, using a universal hose
coupling wrench to tighten coupling firmly. Connect
the footvalve strainer to male end of suction hose,
then fill suction hose with water and connect to
pump intake.
DO NOT
run engine with pump disconnected.
DO NOT
run pump when dry.
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. Unless using the WATERAX hand primer,
connect the discharge hose, nozzles, etc., to
pump
, and tighten firmly with coupling wrench.
4. Prime the pump.
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.
WATERAX hand primer:
Connect hand primer to pump discharge. Pump until water is drawn into the pump.
Install discharge hose, nozzles, etc. to pump and tighten firmly with coupling wrench.
5. Start the engine.
a. Power up DOS: crank engine 1-2 times, DOS LED will blink.
b. Close/engage choke, if engine is cold.
c. Move throttle leve
r to “START”/“WARM UP” position (approximately 3
increments from idle position).
d. If equipped with a decompression switch (located on the cylinder head),
push down the valve. The valve will close automatically upon engine
startup.
e. Slowly crank engine until resistance (past compression).
f.
Give starter cord a quick and steady pull.
g. Once engine starts, slowly open/disengage choke and allow engine to
warm up for a
minimum of 2 minutes
before using full throttle.
Failure to allow the engine to warm up may lead to piston scoring and possibly more serious engine damage.
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. Prime the pump again.
b. The engine works best at wide open throttle. Vary the discharge nozzle opening to adjust the pump
performance.
Important:
Do not use a nozzle larger than ½” (12.7 mm).
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.
