10. Never over fill fuel tank. Fill tank to no more than ½ 

inch below bottom of filler neck to provide space for 
fuel expansion.

11. Replace gasoline cap and tighten securely.
12. If gasoline is spilled, wipe it off the engine and 

equipment. Move unit to another area. Wait 5 
minutes before starting the engine.

13. Never store the machine or fuel container inside 

where there is an open flame, spark or pilot light as 
on a water heater, space heater, furnace, clothes 
dryer or other gas appliances. 

14. To reduce fire hazard, keep mower free of grass, 

leaves, or other debris build-up. Clean up oil or fuel 
spillage and remove any fuel soaked debris. 

15. Allow mower to cool 5 minutes before storing.

General Service:

1.

Never run an engine indoors or in a poorly 
ventilated area. Engine exhaust contains carbon 
monoxide, an odorless and deadly gas.

2.

Before cleaning, repairing, or inspecting, make 
certain the blade and all moving parts have 
stopped. Disconnect the spark plug wire and 
ground against the engine to prevent unintended 
starting. 

3.

Check the blade and engine mounting bolts at 
frequent intervals for proper tightness. Also, 
visually inspect blade for damage (e.g., bent, 
cracked, worn) Replace blade with the original 
equipment manufacture’s (O.E.M.) blade only, 
listed in this manual. “Use of parts which do not 
meet the original equipment specifications may 
lead to improper performance and compromise 
safety!” 

4.

Mower blades are sharp and can cut. Wrap the 
blade or wear gloves, and use extra caution when 
servicing them.

5.

Keep all nuts, bolts, and screws tight to be sure the 
equipment is in safe working condition.

6.

Never tamper with safety devices. Check their 
proper operation regularly.

7.

After striking a foreign object, stop the engine, 
disconnect the spark plug wire and ground against 
the engine. Thoroughly inspect the mower for any 
damage. Repair the damage before starting and 
operating the mower.

8.

Never attempt to make a wheel or cutting height 
adjustment while the engine is running.

9.

Grass catcher components, discharge cover, and 
trail shield are subject to wear and damage which 
could expose moving parts or allow objects to be 
thrown. For safety protection, frequently check 
components and replace immediately with original 
equipment manufacturer’s (O.E.M.) parts only, 
listed here. Use of parts which do not meet the 
original equipment specifications may lead to 
improper performance and compromise safety.

10. Do not change the engine governor setting or 

overspeed the engine. The governor controls the 
maximum safe operating speed of the engine. 

11. Maintain or replace safety and instruction labels, as 

necessary.

12. Observe proper disposal laws and regulations. 

Improper disposal of fluids and materials can harm 
the environment. 

Your Responsibility

Restrict the use of this power machine to persons who read, understand and follow the warnings and 
instructions in this manual and on the machine.
