procedure

• Ensure ignition is ON

• Ensure choke lever is moved 

half way.

• Check fuel level

• Check oil level

• Check if SAE15w40  

engine oil is used.

Comporessor is  

difficult to start

 Worn or dirty  

components

• Check air filter - clean if dirty

• Check fuel filter - clean if dirty

• If the recoil start handle is 

“hard” to pull, it may indicate 

there is too much oil in the engine.  

Ensure engine oil is at the level 

recommended in this manual.

• If the recoil handle is too 

easy to pull, there may not be 

enough compression in the 

 

engine for it to work properly. 

Please contact SGS.
