surrounding area clean at all times.

22. 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.

23. Do not operate the equipment with known 

leaks in the engine’s fuel system.

(California Health & Safety Code § 25249.5, 

et seq.

)

25. 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.

26. Keep hands and feet away from moving parts.  Do 

not reach over or across equipment while operating.

27. 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.

28. Use the correct equipment for the application.

Service Precautions

1. 

Before service, maintenance, or cleaning:

a. 

Turn the engine switch to its “OFF” position.

b. 

Allow the engine to completely cool.

c. 

Then, remove the spark plug 

cap from the spark plug.

2.  Keep all safety guards in place and in 

proper working order.  Safety guards include 

muffler, air cleaner, mechanical guards, 

and heat shields, among other guards.

3. 

Do not alter or adjust any part of the 

equipment or its engine that is sealed by the 

manufacturer or distributor.  Only a qualified 

service technician may adjust parts that may 

increase or decrease governed engine speed.

4.  Wear ANSI-approved safety goggles, 

heavy-duty work gloves, and dust 

mask/respirator during service.

5.  Maintain labels and nameplates on the equipment.   

These carry important information.   

If unreadable or missing, contact 

Harbor Freight Tools for a replacement.

6.  Have the equipment serviced by a qualified repair 

person using only identical replacement parts.  

This will ensure that the safety of the equipment 

is maintained.  Do not attempt any service or 

maintenance procedures not explained in this 

manual or any procedures that you are uncertain 

about your ability to perform safely or correctly.

7.  Store equipment out of the reach of children.
8.  Follow scheduled engine and 

equipment maintenance.

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.
5.  Wipe up any spilled fuel and allow excess 

to evaporate before starting engine. 

To prevent FIRE, do not start the engine 

while the smell of fuel hangs in the air.

 SAVE THESE INSTRUCTIONS.
