APPLICATION (CONTINUED)
4. A suction strainer is required to filter abrasive material
5. The discharge hose and fiting should be leak-tight. A leak in the discharge
hose will allow water to spray around the worksite, 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 on engine crank until 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 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.
MAINTENANCE
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 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
Priming
Port
follow the engine manufacturer's recommendations for long-term storage.
The Honda engine is equipped with a low oil shut off sensor. The SP CK will shut
down and will not restart if the oil level becomes low.
