⚠WARNING
PERSONAL SAFETY
Stay alert, watch what you are doing, and use common sense when operating the water
pump. Do not use the water pump while you are tired or under the influence of drugs, alcohol,
or medication. A moment of inattention while operating the tool may result in serious personal
injury.
Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts. Air vents on the tool often cover moving parts and should be avoided.
Wear the proper personal protective equipment when necessary. Use ANSIZ87.1 compliant
safety goggles (not safety glasses) with side shields, or when needed, a face shield. Use a
dust mask in dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust
collection systems, and hearing protection when appropriate. This applies to all persons in the
work area.
Do not overreach. Keep proper footing and balance at all times.
Remove keys or wrenches before connecting the tool to an air supply, power supply, or turning
on the tool. A wrench or key that is left attached to a rotating part of the tool may cause
personal injury.
⚠CAUTION
WATER PUMP USE AND CARE
Do not force the water pump. Products are safer and do a better job when used in the manner for
which they are designed. Plan your work, and use the correct product for the job.
Check for damaged parts before each use. Carefully check that the water pump will operate
properly and perform its intended function. Replace damaged or worn parts immediately. Never
operate the water pump with a damaged part.
Store the water pump when it is not in use. Store it in a dry, secure place out of the reach of
children. Inspect the water pump for good working condition prior to storage and before re-use.

Page 16 of 35
Before Each Use
Step One: Inspect & Repair
If the water pump has been previously used, it must be prepared BEFORE EACH SUBSEQUENT
USE.
⚠WARNING
Read instructions below carefully for inspecting and preparing the water pump. Damaged or
clogged equipment could result in leaks or uncontrolled spray.
⚠WARNING
IMPORTANT SAFETY RULES
Check oil. Before each use, check the oil level and add oil to the proper level if it's low.
Turn off engine. Turn off the engine and remove the spark plug cap before cleaning,
inspecting, or servicing the water pump.
Guards/shields. Make sure all guards and shields are replaced after servicing the water pump.
Replacement parts. If a part needs replacement, only use parts that meet the manufacturer's
specifications. Replacement parts that do not meet specifications may result in a safety
hazard or poor operation of the water pump.
1. Ensure water pump
casing is empty.
Ensure the water pump has been thoroughly flushed with fresh
water and drained from prior use.
2. Clean suction strainer.
Clean the suction strainer of any material residue.
It is important to clean the suction strainer of debris before each use,
to ensure it is not clogged.
3. Inspect & repair.
Inspect and test the water pump thoroughly.
a. Inspect fittings for cracks and leaks. Replace all damaged
fittings with original parts.
b. Check to be sure all nuts, bolts, and screws are tight.
c. Check the engine’s oil level (see engine’s owner’s manual).
d. Check for fuel leaks. Any fuel leak is a fire hazard and needs to
be repaired before starting engine.

Page 17 of 35
Step Two: Fueling
⚠WARNING
Gasoline is highly flammable and explosive. Use extreme care when handling gasoline.
A running engine is hot enough to ignite fuel. Never add fuel or remove gas cap if engine is
running or still hot.
Gasoline vapors can ignite if they collect inside an enclosure. Explosion can result.
1. Engine off / cool
The engine must be off and allowed to cool at least two minutes
before adding fuel.
2. Outdoor location
Fill fuel tank outdoors –never indoors.
3. Check engine oil level
Check engine oil level as specified in the engine manual.
4. Remove gas cap
Remove engine gas cap.
5. Add gasoline
Add gasoline through fill opening from a UL-approved container.
Important Safety Instructions:
Use approved container. NEVER pump fuel directly into engine at
gas station. Static charge can build and ignite fuel. Use a UL
approved fuel container to transfer gas to the engine.
Don’t overfill. DO NOT overfill the gas tank. Allow at least 1/2” of
empty space below the fill neck to allow for fuel expansion.
Heat / flames / sparks. Stay away from sources of heat, flame, or
sparks while adding fuel.
6. Spills / splashes
Clean up fuel spills/splashes immediately.
a. Move water pump away from spilled fuel.
b. Wipe fuel off engine and wait 5 minutes for excess fuel to
evaporate before starting engine.
c. Gas soaked rags are flammable and should be disposed of
properly.
d. If gasoline is spilled on your skin or clothes, change clothes and
wash skin immediately.
7. Replace gas cap
Replace gas cap securely before starting engine.
8. Gasoline storage
Store gasoline in a cool, dry place, tightly sealed container.

Page 18 of 35
Step Three: Attach a Suction Strainer
⚠WARNING
This pump is designed to pump water only. Never use the water pump to pump flammable liquids.
1. Attach suction strainer
A suction strainer should be attached to the suction hose. A suction
strainer has holes or slots small enough to prevent large debris from
working through and damaging the pump.
2. Keep the strainer clean
Keep the strainer clean. If possible, suspend the strainer to keep it from
working into sediment -OR-
a. Prepare a bed of large stones on which the strainer will rest.
b. Tie the strainer inside a basket or pail.
Step Four: Place the Water Pump
1. Place the water pump
near the liquid surface.
Place the water pump in a location as close to the liquid surface as
possible. This will ensure proper pump suction. All hoses must be kept
as straight as possible, avoiding sharp bends.
NOTE: 23 feet is the maximum height of a suction head.
2. Use a flexible hose.
Use at least 12” of flexible hose to make plumbing connections to the
pump body. Rigid piping may put stress on the pump, causing damage.
3. Place the unit on
secure footing.
Always be sure the unit is on secure footing. Keep the immediate pump
area free of all bystanders. If the water pump is sitting beside a pit, be
sure it is well-anchored so that it does not fall in.
4. Do not run the pump
dry.
Do not run the pump dry. Always fill the pump body with water before
starting. It is not necessary to drain the pump body after each use,
unless there is danger of freezing, settling of solids, or crystallization.
5. Fill the pump with
water.
Fill the pump with water using the priming port on the top of the pump.
(The pump self-primes only when it is first filled with priming water.)
All hoses and pipe connections must be air-tight.

Operating Instructions
Part 1: Operating the Water 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 water 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 B fire extinguisher available as a precautionary
measure when operating the water 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 water pump
engine OUTDOORS and away from air intakes. NEVER run the water 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 water 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 water 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 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.

Safety Precautions
⚠WARNING
Warning
Symbol
Description
Rapid retraction of the starter cord (kickback) can jerk your hands toward the
engine faster than you can let go. Broken bones, fractures, bruises, or sprains
could result.
When starting the engine, pull the cord slowly until resistance is felt, then pull
rapidly.
Components such as blades, impellers, pulleys, sprockets, etc., must be securely
attached.
Rotating parts can contact or entangle hands, feet, hair, clothing, or accessories.
Traumatic amputation or severe laceration can result.
Operate equipment with guards in place.
Keep hands and feet away from rotating parts.
Tie up long hair and remove jewelry.
Do not wear loose-fitting clothing, dangling drawstrings, or items that could
become caught.
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.
