Stop engine according to equipment manufacturer’s 
instructions.

To avoid unsupervised operation of 
an engine, especially by children, 

NEVER leave it unattended when it is running. Always turn 
off the engine after use and remove ignition key, if 
provided.

NEVER store the engine with fuel in 
the fuel tank inside a building with 

potential sources of ignition such as hot water and space 
heaters, clothes dryers, electric motors, etc.

See  "A. Short Term/Seasonal Storage" instructions on page 
15,  for more information.

An adult should perform 
maintenance on this engine. 

Only allow children to perform maintenance if an adult has 
determined they are experienced and capable of such 
operation.

To prevent accidental starting when 
working on equipment always:

• Disconnect spark plug wire and keep it away from 

spark plug. See "G. Avoid Accidental Starts" 
instructions on page 2. See Figure 30.

• Keep the disconnected spark plug wire 

securely away from metal parts where arcing 
could occur. 

• Attach the spark plug wire to the grounding 

post, if provided. 

• Disconnect battery at negative terminal first, if 

engine is equipped with an electric starter.

• Turn off all engine switches.
• Remove ignition key, if provided.

To avoid engine damage, it is important to:

• Check oil level before each use and every 5 

operating hours. See "A. Checking Oil Level" 
instructions on page 4.

• Change oil after first 2 operating hours and every 25 

operating hours thereafter; more often if operated in 
extremely dusty or dirty conditions. Engine should 
still be warm but not hot from recent use.

1. Be sure you find the correct drain plug location, if pro-

vided. See Figure 30.

2. Disconnect spark plug wire and keep it away from 

spark plug. See "G. Avoid Accidental Starts" instruc-
tions on page 2.

• Keep the disconnected spark plug wire securely 

away from metal parts where arcing could occur. 

• Attach the spark plug wire to the grounding post, if 

provided.

3. Be sure the gas cap is on and is tightened securely.
4. Clean area around oil drain plug. See Figure 30.
5. Place approved recyclable oil container under oil drain 

plug, tipping engine to position the oil drain plug at the 
lowest point on the engine. (See equipment manufac-
turer’s instructions).

6. Remove oil drain plug and drain oil. 

See Figure 30. 

7. Install oil drain plug and tighten 

securely.

8. Fill with recommended oil. See "III. Oil and Fuel Speci-

fications" instructions on page 3. See Table 1 on page 
3 and Figure 2 on page 2. 

9. Wipe away any spilled oil.
10. Carefully disconnect spark plug wire from grounding 

post, if provided.

11. Carefully re-connect spark plug wire to spark plug. See
