Checking and Filling Fuel

WARNING!

 

TO pREVENT SERIOUS 

INJURY FROM FIRE:

 

Fill the fuel tank in a well-ventilated area 

away from ignition sources.  If the engine is 

hot from use, shut the engine off and wait 

for it to cool before adding fuel. 

Do not smoke. 
1.  Clean the Fuel Cap and the area around it.
2.  Unscrew and remove the Fuel Cap.
3.  If needed, fill the Fuel Tank to about 1 inch 

under the fill neck of the Fuel Tank with 

87 octane or higher unleaded gasoline.

Note: Do not use gasoline containing more than 

10% ethanol (E10).  Do not use E85 ethanol.
Note: Do not use gasoline that has been stored in a 

metal fuel container or a dirty fuel container.  It can 

cause particles to enter the carburetor, affecting 

engine performance and/or causing damage.

4.  Then replace the Fuel Cap.
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.

Engine Oil Change

CAUTION!

  Oil is very hot during operation and can 

cause burns.  Wait for engine to cool before changing oil.
1.  Make sure the engine is stopped and is level.
2.  Close the Fuel Valve.
3.  Place a drain pan (not included) underneath 

the crankcase’s drain plug.

4.  Remove the drain plug and, if possible, tilt the 

crankcase slightly to help drain the oil out.  

Recycle used oil.

5.  Replace the drain plug and tighten it.
6.  Clean the top of the Dipstick and the 

area around it.  Remove the Dipstick 

by threading it counterclockwise, and 

wipe it off with a clean lint free rag.

7. 

Full level

Add the appropriate type of oil until the oil level is at 

the full level.  SAE 10W-30 oil is recommended for 

general use.
