Operating Instructions and Replacement Parts List
2
An air leak in the
suction line may
prevent priming of the pump. Use of
thread sealant is recommended.
Suction lines must be reinforced
hose or rigid pipe. Non-reinforced
hose will collapse due to the suction
created by the pump and prevent
pump from operating.
3. A check valve must be used in the
suction line to maintain the self-
priming capability. If no check valve
is used the pump will need to be
primed at the start of each
operation. For best operation, the
check valve should be installed at the
intake of the suction line.(Figure 2).
4. A suction strainer is required to
filter abrasive material.
5. The discharge hose and fitting
should be leak-tight. A leak in the
discharge hose will allow water to
spray around the work site, making
the site hazardous.
6. Keep all pipes and hose lines as
short and straight as possible. Long
lengths and curves in the pipes and
hose lines will reduce the pressure
the pump develops.
7. Fill the engine crankcase with oil.
Refer to the engine operating
manual for the specific grade of oil
and amount required.
8. Fill the engine fuel tank with
gasoline. Refer to the engine
operating manual for specific
gasoline type that is most efficient
for this engine.
9. Add water to the priming port on
the pump (See Figure 3). Continue
adding water until the water level is
approximately 3 inches from the
top. Install the priming plug. The
water in the pump will create the
suction that primes the pump.
10. Turn fuel valve to ‘ON’ position.
11. Move choke lever to ‘CHOKE’
position.
12. Move throttle lever to ‘START’
position.
13. Pull engine crank until engine starts.
Once engine starts, move choke
lever to ‘RUN’ position.
14. The pump will take several minutes
to prime.
PIPING
Always place the pump as close as
possible to the liquid being pumped.
Keep all pipe and hose lines as short and
straight as possible.
Support pump and
piping when
assembling and after installation. Failure
to do so may cause piping to break, pump
to fail, etc; all of which can result in
property damage and/or personal injury.
All suction connections must be airtight.
If the pump won’t prime, check for leaks
in the suction piping or fittings. If flexible
suction hose is used instead of pipe, use
reinforced hose with a two inch inner
diameter. Non-reinforced flexible hose
may collapse from the vacuum created as
the pump primes.
Always use a strainer at the end of the
suction pipe or hose. Position strainer so
it doesn’t become clogged with stones or
debris. A suction line check valve is
recommended.

Do not use this pump for suction lifts
over twenty-five feet.
Always shut off the engine, allow the
engine to cool, and remove the spark
plug before performing any
maintenance.
During freezing weather, open the drain
port and allow all the water in the pump
to drain. This will prevent damage to the
pump when the water freezes. If the
pump will be stored for a month or
more, drain the water from the pump
and follow the engine manufacturer’s
recommendations for long-term storage.
The Honda engine is equipped with a
low oil shut off sensor. The enigne will
shut down and will not restart if the oil
level becomes low.
