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 with 87 octane or higher 

unleaded gasoline that has been treated with 

a fuel stabilizer additive. Follow fuel stabilizer 

manufacturer’s recommendations for use.

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

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.  

The SAE Viscosity Grade chart shows other 

viscosities to use in different average temperatures.

8.  Thread the dipstick back in clockwise.

CAUTION!

  Do not run the engine with too little oil.  

The engine will be permanently damaged.

Air Filter Element Maintenance

1.  Remove the air filter cover and the air filter elements 

and check for dirt. Clean as described below.

2. 

Cleaning:

•  For “paper” filter elements: 

To prevent injury from dust and debris, 

wear ANSI-approved safety goggles, 

NIOSH-approved dust mask/respirator, and 

heavy-duty work gloves.  In a well-ventilated 

area away from bystanders, use pressurized 

air to blow dust out of the air filter. 

•  For foam filter elements: 

Wash the element in warm water and 

mild detergent several times. Rinse. 

Squeeze out excess water and allow it to dry 

completely.  Soak the filter in lightweight oil 

briefly, then squeeze out the excess oil.

3.  Install the cleaned filter.  Secure the 

Air Cleaner Cover before use.
