Safety
TO PREVENT SERIOUS INJURY:
Operate only with proper spark arrestor installed.
Operation of this equipment may create sparks that can start fires around dry vegetation.
A spark arrestor may be required. The operator should contact local fire agencies
for laws or regulations relating to fire prevention requirements.
High Altitude Operation Above 3000 feet
WARNING! To prevent serious injury from fire:
Follow instructions in a well-ventilated area away from ignition sources.
If the engine is hot from use, shut the engine off and wait for it to cool before proceeding. Do not smoke.
NOTICE: Warranty void if necessary adjustments are not made for high altitude use.
Setup
At high altitudes, the engine’s carburetor, governor (if so equipped), and any other parts that control the fuel-air
ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude use and to prevent damage
to the engine and any other devices used with this product. The fuel system on this engine may be influenced by
operation at higher altitudes. Proper operation can be ensured by installing an altitude kit at altitudes higher than
3000 ft. above sea level. At elevations above 8000 ft, the engine may experience decreased performance, even
with the proper main jet. Operating this engine without the proper altitude kit installed may increase the engine’s
emissions and decrease fuel economy and performance. The kit should be installed by a qualified mechanic.
1. Turn off the engine.
2. Close the fuel valve.
3. Place a bowl under the fuel cup to catch any spilled fuel.
CAUTION! Carburetor bowl may have gas in it which will leak upon removing the bolt.
4. Unthread the bolt holding the fuel cup.
Operation
5. Remove the bolt, Bolt Seal, fuel cup, Fuel Cup Seal and Main Jet from the body of the carburetor assembly.
A carburetor screwdriver (not included) is needed to remove and install the Main Jet.
Note: The mixing tube is held in place by the Main Jet and might fall out when it is removed. If it falls out,
replace it in the same orientation before replacing the Main Jet.
6. Replace the Main Jet with the replacement Main Jet
needed for your altitude range (part 1a or 2a).
Note: The Fuel Cup Seal and Bolt Seal may be damaged during
removal and should be replaced with the new ones from the kit.
7. Replace the Fuel Cup Seal (4a), fuel cup,
Bolt Seal (3a), and bolt. Tighten in place.
CAUTION: Do not cross thread bolt when tightening.
Finger tighten first and then use a wrench to
make sure the bolt is properly threaded.

Locating the Water Pump
1. For best Pump performance, place the
Pump near the water level and use hoses
that are no longer than necessary. Attach a
foot valve (sold separately) near the bottom
of the intake line. See diagram below.
Discharge Head
Total Head
As the head (pumping height) increases,
pump output decreases. A non-collapsible
suction hose must be used. The length, type,
and size of the suction and discharge hoses
can significantly affect Pump output.
Discharge head capability is always greater than
suction head capability. This means pumping height
for the Intake Hose (suction head) should be shorter
than the pumping height for the Discharge Hose.
Minimizing suction head (placing the Pump
closer to the water level) will also help make it
easier to prime the pump (fill it with water).
2. Route the Intake Hose with the Intake Strainer
fully immersed in the water supply source.

3. Place Strainer into water to be pumped.
CAUTION: Immerse strainer fully in water.
Do not operate Pump without Strainer connected
to end of suction hose. Keep Strainer out of sand
or silt by placing Strainer in a bucket or on stones.
For technical questions, please call 1-888-866-5797.

Maintenance
Locate the Water Pump on a flat, level, sturdy surface
capable of supporting the weight of the Pump.
Operation
Discharge Port
NOTICE: Air leaks must not appear in the
suction line. If there is an air leak in the suction
line, you will not be able to prime the pump.
Use a thread sealant to seal air leaks.
Safety
Strainer
4. Secure the Intake Hose in place to keep it
from moving once the Pump is turned on.
The Intake Hose should be as short as
possible for more efficient operation.
Setup
5. Route the discharge hose to the desired discharge
location. If necessary, connect additional discharge
hoses to direct the discharge to the desired location.
Make sure to secure the discharge hose in place
to keep it from moving once the Water Pump is
turned on. The discharge hose should be kept as
short as possible for more efficient operation.
Operation Concerns
1. Cavitation: This is the sudden formation and
collapse of low-pressure vapor (bubbles)
across the vanes of the impeller.
Cause: When the surface pressure on a liquid
becomes low enough, the liquid will begin to boil
(even at room temperature). With centrifugal
pumps, cavitation can occur when the suction
vacuum becomes too great, allowing water vapor
or bubbles to form at the impeller. The rapid
pressure increase can cause impeller damage.
Solution: Minimizing suction head and using
the largest practical suction hose diameter will
reduce the likelihood of cavitation. Do not use
a suction hose with a diameter smaller than
the Pump’s Intake Port (1" diameter).
2. Water Hammer Pressure: This is energy
sent back to the Pump due to sudden
stoppage of water flowing from the Pump.
Cause: Water hammer pressure is more likely to
occur when using a very long discharge hose. If the
flow of water at the end of the discharge hose is shut
off suddenly, energy is sent back to the pump. This
causes a large pressure spike in the Pump housing,
leading to potential damage to the Pump casing.
Solution: Use as short a discharge
hose as possible and turn off water
pump before closing water flow.
Operation
Operation
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual

NOTICE: Using an incorrect spark plug
may damage the engine.
4. When installing a new spark plug, adjust
the plug’s gap to the specification on the
Specifications chart. Do not pry against the
electrode, the spark plug can be damaged.
5. Install the new spark plug or the cleaned spark plug
into the engine. Gasket-style: Finger-tighten until
the gasket contacts the cylinder head, then tighten
about 1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until
the plug contacts the head, then
tighten about 1/16 turn more.
NOTICE: Tighten the spark plug properly.
If loose, the spark plug will cause the engine to
overheat.
If overtightened, the threads in the
engine block will be damaged.
6. Apply dielectric spark plug boot protector
(not included) to the end of the spark
plug and reattach the wire securely.
Long Term Storage
Operation
When the equipment is to remain idle for longer than
20 days, prepare the engine for storage as follows:
1. CLEANING:
Wait for engine to cool, then clean engine with
dry cloth. NOTICE: Do not clean using water.
The water will gradually enter the engine
and cause rust damage. Apply a thin coat
of rust preventive oil to all metal parts.
4. BATTERY:
Disconnect battery cables (if equipped).
Recharge batteries monthly while in storage.
5. STORAGE AREA:
Cover and store in a dry, level, well-ventilated
area out of reach of children. Storage area
should also be away from ignition sources, such
as water heaters, clothes dryers, and furnaces.
2. FUEL:
NOTICE: For every 3 months of an extended
storage period, the pump must be connected to a
water supply, primed, started, and allowed to run
for 15 – 20 minutes or the Warranty is VOID.
6. AFTER STORAGE:
Before starting the engine after storage, keep in
mind that untreated gasoline will deteriorate quickly.
Drain the fuel tank and change to fresh fuel if
untreated gasoline has been sitting for a month,
if treated gasoline has been sitting beyond
the fuel stabilizer’s recommended time
period, or if the engine does not start.
To protect the fuel tank during storage, fill the
tank with gasoline that has been treated with
a fuel stabilizer additive. Follow fuel stabilizer
manufacturer’s recommendations for use. Refer
to Checking and Filling Fuel on page 11.
