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.  Keep all spectators at least six feet 

from the Engine during operation.

4.  Fire Hazard! Do not fill fuel tank while engine is 

running. Do not operate if gasoline has been spilled. 

Clean spilled gasoline before starting engine. 

Do not operate near pilot light or open flame.

5.  Do not touch engine during use. 

Let engine cool down after use. 

6.  Never store fuel or other flammable 

materials near the engine.

7.  Only use a suitable means of transport and 

lifting devices with sufficient weight bearing 

capacity when transporting the engine.

8.  Secure the engine on transport vehicles to 

prevent it from rolling, slipping, and tilting.

9.  Industrial applications must follow 

OSHA requirements.

10. The engine can produce high noise levels.  

Prolonged exposure to noise levels 

above 85 dBA is hazardous to hearing. 

Wear ear protection when operating the or 

when working nearby while it is operating.

11.  Wear ANSI-approved safety glasses 

and hearing protection during use.

12. 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.

13. 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.

14. 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.

15. Stay alert, watch what you are doing and use 

common sense when operating this engine.  

Do not use while tired or under the influence 

of drugs, alcohol or medication.

16. 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.

17. Parts, especially exhaust system components, 

get very hot during use.  Stay clear of hot parts.

18. Do not cover the engine during operation.
19. Keep the engine and surrounding 

area clean at all times.

20. Do not smoke, or allow sparks, flames, 

or other sources of ignition around the 

equipment, especially when refuelling.

21. 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.

22. Do not operate the equipment with known 

leaks in the engine’s fuel system.

23. 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.

24. Keep hands and feet away from moving parts.   

Do not reach over or across 

equipment while operating.

25. 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.

26. 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.
