Safety Warnings
WARNING! Read all instructions.
Failure to follow all instructions listed below may result in fire, serious injury and/or DEATH.
SAFETY OPERATION MAINTENANCESETUP
The warnings and precautions discussed in this manual cannot cover all possible conditions and
situations that may occur. It must be understood by the operator that common sense and caution
are factors which cannot be built into this product, but must be supplied by the operator.
Set up Precautions
SAVE THESE INSTRUCTIONS
1. Gasoline fuel and fumes are flammable, and
potentially explosive. Use proper fuel storage
and handling procedures. Do not store fuel
or other flammable materials nearby.
2. Have multiple ABC class fire extinguishers nearby.
3. 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.
4. Set up and use only on a flat, level,
well‑ventilated surface.
5. Use only lubricants and fuel recommended
in the Specifications chart of this manual.
6. Wear ANSI‑approved safety goggles, heavy‑duty
work gloves, and dust mask/respirator during set up.
Engine Precautions
Follow engine precautions and instructions in the included engine instruction manual.
Operating Precautions
1. CARBON MONOXIDE HAZARD
Using an engine indoors CAN KILL
YOU IN MINUTES.
Engine exhaust contains carbon
monoxide. This is a poison you cannot
see or smell.
NEVER use inside a home or garage, EVEN IF doors
and windows are open.
Only use OUTSIDE and far away from windows,
doors, and vents.
2. Keep children away from the equipment,
especially while it is operating.
3. Do not touch Pump engine during use.
4. Never store fuel or other flammable
materials near the Pump engine.
5. Industrial applications must follow
OSHA requirements.
6. Do not leave the equipment unattended when it is
running. Turn off the equipment (and remove safety
keys, if available) before leaving the work area.
7. Engine can produce high noise levels.
Prolonged exposure to noise levels above
85 dBA is hazardous to hearing. Always wear
ear protection when operating or working
around the gas engine while it is operating.
8. Wear ANSI‑approved safety glasses, hearing
protection, and NIOSH‑approved dust mask/
respirator under a full face shield along
with steel‑toed work boots during use.
9. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to a heart pacemaker could cause
pacemaker interference or pacemaker failure.
Caution is necessary when near the
engine’s magneto or recoil starter.
10. Use only accessories that are recommended
by Harbor Freight Tools for your model.
Accessories that may be suitable for one
piece of equipment may become hazardous
when used on another piece of equipment.
11. Do not operate in explosive atmospheres,
such as in the presence of flammable
liquids, gases, or dust. Gasoline‑powered
engines may ignite the dust or fumes.

Operating Precautions (cont.)
12. Stay alert, watch what you are doing and
use common sense when operating this
piece of equipment. Do not use this piece of
equipment while tired or under the influence
of drugs, alcohol or medication.
13. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the equipment in unexpected situations.
14. Dress properly. Do not wear loose clothing or
jewelry. Keep hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or
long hair can be caught in moving parts.
15. Parts, especially exhaust system components,
get very hot during use. Stay clear of hot parts.
16. Do not cover the engine or
equipment during operation.
17. Keep the equipment, engine, and
surrounding area clean at all times.
18. Use the equipment, accessories, etc., in accordance
with these instructions and in the manner intended for
the particular type of equipment, taking into account
the working conditions and the work to be performed.
Use of the equipment for operations different from
those intended could result in a hazardous situation.
19. Do not operate the equipment with known
leaks in the engine’s fuel system.
20. This product contains or, when used, produces a
chemical known to the State of California to cause
cancer and birth defects or other reproductive harm.
(California Health & Safety Code § 25249.5, et seq.)
21. When spills of fuel or oil occur, they must be
cleaned up immediately. Dispose of fluids and
cleaning materials as per any local, state, or
federal codes and regulations. Store oil rags in
a bottom‑ventilated, covered, metal container.
22. Keep hands and feet away from moving
parts. Do not reach over or across
equipment while operating.
23. Before use, check for misalignment or
binding of moving parts, breakage of parts,
and any other condition that may affect the
equipment’s operation. If damaged, have the
equipment serviced before using. Many accidents
are caused by poorly maintained equipment.
24. Use the correct equipment for the application.
Do not modify the equipment and do not use the
equipment for a purpose for which it is not intended.

Refueling:
1. Do not smoke, or allow sparks, flames,
or other sources of ignition around the
equipment, especially when refuelling.
2. Do not refill the fuel tank while the
engine is running or hot.
3. Do not fill fuel tank to the top. Leave a little
room for the fuel to expand as needed.
4. Refuel in a well‑ventilated area only.
