Read the ENTIRE IMpORTANT SAFETY INFORMATION section at the beginning of this manual 

including all text under subheadings therein before set up or use of this product.

pre-Start Checks

Inspect engine and equipment looking for damaged, loose, and missing parts before set up 

and starting.  If any problems are found, do not use equipment until fixed properly.

Checking and Filling Engine Oil
NOTICE:  Your Warranty is VOID if the engine’s 

crankcase is not properly filled with oil before 

each use.  Before each use, check the oil level.  

Do not run the engine with low or no engine oil.  

Running the engine with no or low engine oil 

WILL permanently damage the engine.

1.  Make sure the engine is stopped and is level.
2.  Close the Fuel Valve.
3.  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.

4. 

Full level

Full level

Reinsert the Dipstick without threading it in and 

remove it to check the oil level.  The oil level 

should be up to the full level as shown above.

5.  If the oil level is at or below the low mark add the 

appropriate type of oil until the oil level is at the 

proper level.  SAE 10W-30 oil is recommended 

for general use.  (The SAE Viscosity Grade chart 

on page 12 in the Service section shows other 

viscosities to use in different average temperatures.)

6.  Thread the dipstick back in clockwise.

NOTICE:  Do not run the engine with too little oil.  

The engine will be permanently damaged.

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.
