Operating Instructions
Part 1: Operating the Pump
⚠WARNING
Review safety information provided in this manual.
Use the priming port on the top of the pump. Completely fill the pump chamber with water before
starting the engine.
Follow these safety rules and precautions when running the pump’s engine:
Hot muffler. If you are starting a warm engine, stay clear of the muffler. It may still be hot
enough to burn you.
Hot exhaust. Hot exhaust fumes from the engine can cause fire. Position muffler at least 7'
from combustible objects during operation.
Fire extinguisher. Have a Class ABC fire extinguisher available as a precautionary measure
when operating the pump engine in dry areas.
Carbon monoxide. The running engine gives off carbon monoxide, a poisonous gas that can
kill you. You CANNOT smell it, see it, or taste it. ONLY run the pump engine OUTDOORS
and away from air intakes. NEVER run the pump engine inside homes, garages, sheds, or
other semi-enclosed spaces. These spaces can trap poisonous gases, EVEN if you run a fan
or open windows. If you start to feel sick, dizzy, or weak while using the pump, shut off the
engine and get to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide
poisoning.
Before starting the engine, consult the engine’s Owner’s Manual.
Throttle control. When operating the pump much higher than the water surface, you may need to
speed up the engine, using the throttle. When the pump is near the water surface, a slower engine
speed can be used. This will save the engine life and fuel. Consult the engine’s Owner’s Manual
for the throttle location.
Secure the flexible hose. Never allow a vehicle to run over the flexible hose. This sudden shut off

Page 13 of 32
pressure can cause “hydraulic shock”. If your flexible hose must be laid across a high traffic area,
it is advised to protect the flexible hose with planking.
Keep the pump from freezing. Never allow water to freeze the pump. Freezing water can be
extremely dangerous to the pump. Always drain the water from the pump if freezing temperatures
are a factor.
Flush the pump with fresh water after each use. Some liquids being pumped may leave a solid or
sticky residue. This may shorten the life of the pump.
⚠CAUTION
HIGH ALTITUDE OPERATION
Operating at an altitude of greater than 2000 feet (610 meters) may affect your engines performance,
fuel consumption, and emissions. To remain emissions compliant and improve engine performance
at higher altitudes, a high-altitude kit is required. A high altitude kit includes a carburetor jet resized
to help correct air / fuel mixture at altitude. To order a high altitude kit or if you have additional
questions, go to www.northerntool.com or contact us at 1-877-234-6869. Please note, engines with
the high-altitude kit installed operated at lower altitudes could cause severe engine damage and
affect emissions compliance. When modified, a tag or decal should be added to the product stating
that a high-altitude kit was installed and to remind you to re-service the carburetor (re-jet) when
operating in lower altitude environments.

Page 14 of 32
Engines give off carbon monoxide, an odorless, colorless, poisonous gas.
Start and run the engine outdoors.
Do not start or run the engine in enclosed areas, even if doors or windows are
open.
Running engines produce heat. Engine parts, especially mufflers, become
extremely hot. Severe thermal burns can occur on contact. Combustible debris,
like leaves, grass, and brush, can catch fire.
Allow the muffler, the engine cylinder, and the fins to cool before touching.
Remove accumulated debris from the muffler and cylinder areas.
Install and maintain in working order a spark arrester before using equipment on
forest-covered, grass-covered, brush-covered unimproved land. The state of
California requires this. Other states may have similar laws. Federal laws apply on
federal land.
Starting an engine creates sparks. Sparking can ignite nearby flammable gases.
Explosion and fire could result.
If there is natural or an LP gas leakage in the area, do not start the engine.
Do not use pressurized starting fluids because vapors are flammable.
Gasoline and its vapors are extremely flammable and explosive. Fire or explosion
can cause severe burns or death. When adding fuel:
Turn the engine OFF and let the engine cool for at least 2 minutes before
removing the gas cap.
Fill the fuel tank outdoors or in a well-ventilated area.
Do not overfill the fuel tank.
Keep gasoline away from sparks, open flames, pilot lights, heat, and other ignition
sources.
Check fuel lines, the tank, the cap, and fittings frequently for cracks or leaks.
Replace if necessary.
When Starting Engine:
Make sure the spark plug, muffler, fuel cap, and air cleaner are in place.
Do not crank the engine with the spark plug removed.
If fuel spills, wait until it evaporates before starting the engine.
If the engine floods, set the choke to the OPEN/RUN position, place the throttle in
FAST, and crank until the engine starts.
When Operating Equipment:
Do not choke the carburetor to stop the engine.
When Transporting Equipment:
Transport with the fuel tank EMPTY.
When Storing Gasoline or Equipment with Fuel in Tank:
Store away from furnaces, stoves, water heaters, or other appliances that have a
pilot light or other ignition source because they can ignite gasoline vapors.

Pre-Operation: Engine Oil Inspection
CAUTION
Engine oil is a key factor in the engine's performance. Do not apply engine oil
with additives or 2-stroke gasoline oil.
Check the engine while it’s stopped on level ground. The recommended engine oil is: SAE 10W-30.
Viscosity varies by region and temperature, so the lubricant has to be selected in accordance with our
recommendation.
Check Engine
1. Ensure that the engine is stopped on level ground.
2. Remove the dipstick and clean it.
3. Reinsert the dipstick into the oil filler without screwing it, and check the oil level.
4. If the level is too low, add the recommended engine oil to the oil filler neck.
5. Reinstall the dipstick.
CAUTION
Operating with insufficient engine oil may severely damage the engine.
Fuel & Fuel Tank
To ensure that the engine runs smoothly, use only FRESH, UNLEADED GAS WITH AN OCTANE
RATING OF 87 OR HIGHER. Using unleaded gasoline will decrease the possibility of producing car
boll deposit and will prolong the engine’s service life. Never apply used or polluted gasoline or a
mixture of gasoline with the engine oil. Make sure the fuel is free of dirt and water.
Gasoline Containing Alcohol
If you decide to use gasoline containing alcohol (fuel blend), be sure its octane rating is at least as
high as that recommended by the company. There are two types of “gasohol”. One contains ethanol,
and the other contains methanol. Neither gasoline containing more than 10% ethanol nor 5%
methanol should be used. If the methanol content in the fuel blend exceeds 5%, it may result in poor
engine performance, as well as damaging metal, rubber, and plastic parts.
CAUTION
Fuel can damage paint and some types of plastic. Be careful not to spill fuel
when filling your fuel tank
It is normal to hear an occasional “spark knock” or “pinking” with the engine running under a heavy
load.
If a "spark knock" or "pinking" occurs at a steady speed under the normal load, change the brand of
gasoline; if such occurrences still happen, consult your dealer for help, otherwise the engine may be
damaged.

Starting the Engine
⚠WARNING
EXPLOSION/BURN HAZARD
Gasoline is extremely flammable and is explosive under certain conditions. Only refuel
in a well-ventilated area with the engine off.
Do not smoke or allow flames or sparks in the area where gasoline is stored or where
the fuel tank is refueled.
Do not overfill the tank (there should be no fuel in the filler neck). After refueling, make
sure the fuel filler cap is set back securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any
fuel is spilled, make sure the area is dry before starting the engine.
Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of
reach of children.
1. To start a cold engine, move the choke lever to the close position. To restart a warm engine, leave
the choke lever in the open position. The choke lever opens and closes the choke valve in the
carburetor. The closed position enriches the fuel mixture for starting a cold engine. The open
position provides the correct fuel mixture for operation after starting, and for restarting a warm
engine.
2. Move the throttle lever away from the slow position, about 1/3 of the way toward the fast position.
The throttle controls engine speed. Moving the throttle lever in one direction or the other makes
the engine run faster or slower.

Page 18 of 32
3. Turn the engine switch to the ON position. The engine switch enables and disables the ignition
system. The engine switch must be on the ON position for the engine to run. Turning the engine
switch to the OFF position stops the engine.
4. Operate the Recoil Starter: Pull the starter grip lightly until you feel resistance, then pull briskly.
Return the starter grip gently. Pulling the starter grip operates the recoil starter to crank the
engine.
5. If the Choke lever has been moved to the Closed position to start the engine, gradually move it to
the Open position as the engine warms up.

Page 19 of 32
Setting Engine Speed
Position the throttle lever for the desired engine speed.
Moving the throttle lever in the directions shown makes the engine run faster or slower.
After starting the engine, move the throttle lever to the Fast position and check the pump output.
The pump output is controlled by adjusting the engine speed. Moving the throttle lever in the Fast
direction will increase pump output, and moving the throttle lever in the Slow direction will decrease
pump output.
Stopping The Engine
To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal
conditions, use the following procedure.
1. Move the throttle lever to the Slow position.

Page 20 of 32
2. Turn the engine switch to the OFF position.
After Each Use
After use, remove the pump drain plug, and drain the pump chamber. Remove the filler cap, and flush
the pump chamber with clean, fresh water. Allow the water to drain from the pump chamber, then
reinstall the filler cap and drain plug.
