Engine Preparation
Engine Oil
NOTE: Engine oil is a major factor affecting
the performance and service life of this water
pump. Non-detergent and 2-stroke engine oils
WILL damage the engine and are not recom-
mended.
1. Use 4 stroke oil, or an equivalent high deter-
gent, premium quality motor oil certified to
meet or exceed U.S. automobile manufactur-
er’s requirements for Service Classification
SG, SF/CC, CD. This designation will be on
the motor oil container.
2. SAE 10W-30 is recommended for general, all-
temperature use. See chart for appropriate
weights for your area.
3. Locate the oil filler cap and remove.
4. Fill oil reservoir according to the engine oil
capacity found in table 1.
5. Confirm proper fill by replacing the dip stick
and checking the oil level.
Fueling the Engine
WARNING
• Gasoline is extremely flammable and
is explosive under certain conditions.
• Fuel and refuel in a well ventilated ar-
ea with the engine stopped.
• Do not smoke or allow flames or
sparks in the area where the engine is
being refueled or where gasoline is
stored.
• Do not over fill the tank (there should
be no fuel in the filler neck).
• After refueling, make sure the tank
cap is closed properly and securely.
• Be careful not to spill fuel when fueling
or refueling. Spilled fuel or fuel vapor
may ignite.
• If fuel is spilled make sure the area is
dry and free of fumes before starting
the engine.
• Avoid fuel contact with the skin or
breathing vapors for a prolonged peri-
od.
• KEEP FUEL OUT OF THE REACH
OF CHILDREN.
1. Unleaded gasoline with a octane rating of 86 or
higher is recommended because it produces
fewer engine and spark plug deposits and ex-
tends the exhaust system life.
2. Remove tank cap and fill tank.
3. Do not fill tank above the shoulder of the fuel
strainer.
4. Never use stale or contaminated gasoline or
oil/gasoline mixture. KDAR recommends a
fuel stabilizer.
5. Avoid getting dirt or water in the fuel tank.

Operation
Pre-Start Preparation
NOTE: The following procedures are to be
completed each time the water pump is started.
General Condition
1. Look around and underneath the pump for
signs of oil or gasoline leaks.
2. Check that all nuts, bolts, screws, hose con-
nectors and clamps are tightened.
3. Remove any excessive dirt or debris, especial-
ly around the muffler and recoil starter.
4. Look for signs of damage.
WARNING
Improperly maintaining this pump, or failing to
correct a problem before operation, could cause
a malfunction that may result in serious injury.
Always perform a pre-operation inspection be-
fore each operation and correct any problem.
Suction & Discharge Hoses
1. Check the general condition of any hose that is
to be connected to the water pump and be sure
they are in serviceable condition.
Note: The suction hose must be reinforced
construction to prevent collapse.
2. Insure the sealing washer in the suction hose
connector is in good condition.
3. Check that hose connectors and clamps are
properly and securely installed.
4. Make sure the strainer is in good condition and
connected to the suction hose.
Engine
1. Check engine oil level and add if the level is
low.
2. Check the air filter to insure it is clean and free
of obstructions.
3. Check the fuel level to insure tank is full.
Pump Placement
For best pump performance, place the pump near
the water level and use hoses that are no longer
then necessary. This will enable the pump to pro-
duce the greatest output.
As head (pumping height) increases, pump output
decreases. Maximum head specifications are show
in Table 1 on page 3. The length, type and size of
the suction and discharge hoses can also signifi-
cantly effect the pump output.
Discharge head capacity is always greater than
suctions head capacity, so it is important for the
suction head to be the shorter part of the total
head.
Minimizing suction head (placing the pump near
the water level) is also very important for reducing
self-priming time. Self-priming time is the time it
takes the pump to bring water the distance of the
suction head during initial operation.

Internal Oiling
1. Remove the spark plug.
2. Pour 1 tablespoon of clean engine oil into the
cylinder.
3. Crank the engine several times by pulling on
the starter rope.
4. Reinstall the spark plug.
5. Slowly pull the starter rope until resistance is
felt. At this point the piston is coming up on its
compression stroke and both the intake and
exhaust valves are closed. Storing the engine in
this position will help protect it from internal
corrosion.
Safety Features
Low-Oil Shutdown
This water pump is equipped with low-oil shut-
down. If the oil level in the engine gets too low the
engine will shut down automatically. This prevents
damage to the engine resulting from insufficient
lubrication.
It the engine shuts down and the oil is at the proper
level, make sure the water pump is on a level sur-
face. Having the unit at an angle may shift the oil
giving the sensor a false reading.
Spark Arresting Muffler
All Hot Max water pumps are equipped with spark
arresting mufflers allowing for use around agricul-
tural crops, forests, brush, grass and other similar
items. Spark arresting mufflers are required in the
State of California and on some U.S. Forest Ser-
vice Land and may also be legally required under
other statutes and ordinances. The California stat-
ues requiring a spark arresting muffler are Sections
13005(b), 4442 and 4443.
Replacement Parts
The emission control systems on your engine were
designed, built, and certified to conform with EPA
and California emission regulations. We recom-
mend the use of original replacement parts when-
ever you have maintenance done. These original-
design replacement parts are manufactured to the
same standards as the original parts, so you can be
confident of their performance. The use of replace-
ment parts that are not of the original design and
quality many impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part assumes the
responsibility that the part will not adversely affect
emission performance. The manufacturer or re-
builder of the part must certify that use of the part
will not result in a failure of the engine to comply
with emission regulations.

High Altitude Operation
At high altitude, the standard carburetor air-fuel
mixture will be too rich. Performance will de-
crease, and fuel consumption will increase. A very
rich mixture will also foul the spark plug and
cause hard starting. Operation at an altitude that
differs from that at which this engine was certified,
for extended periods of time, may increase emis-
sions.
High altitude performance can be improved by
specific modifications to the carburetor. If you al-
ways operate your engine at altitudes above 5,000
feet (1,500 meters), have a qualified mechanic per-
form this carburetor modification. This engine,
when operated at high altitude with the carburetor
modifications for high altitude use, will meet each
emission standard throughout its useful life.
Even with carburetor modification, engine horse-
power will decrease about 3.5% for each 1,000-
foot (300-meter) increase in altitude. The effect of
altitude on horsepower will be greater than this if
no carburetor modification is made.
NOTICE: When the carburetor has been modified
for high altitude operation, the air-fuel mixture
will be too lean for low altitude use. Operation at
altitudes below 5,000 feet (1,500 meters) with a
modified carburetor may cause the engine to over-
heat and result in serious engine damage. For use
at low altitudes, have a qualified mechanic return
the carburetor to original factory specifications.
