Carburetor 

Never tamper with factory setting of the carburetor.  

Cooling Fins  

Cooling fins, air inlets and linkages must be free from any debris before each use.  

Air Filter  

Never run engine without air cleaner properly installed. Added wear and engine failure may occur if air cleaner is not 
installed on engine.  

Service air cleaner every 3 months or after 20 hours of operation. Clean filter daily in extremely dusty conditions. 

STEPS FOR REPLACING AND CLEANING AIR FILTER (BLOCK STYLE FOAM FILTER) 

1.

Before removing the air filter cover, move the choke lever 
to the CHOKE position. 

2.

To remove air filter cover, unscrew the cover bolt with a 
screw driver and gently pop out the front latch tab 
(

Figure 12

). The cover then can be slid off the back latch 

tabs and away from the engine.

Figure 10 

Proper position for checking oil level or re-filling oil is face 
down, with the gas tank of the Tiller down on a horizontal 
surface (

Figure 10

). Failure to maintain this position can 

result in over filling the engine with oil which will impair the 
engine’s performance.
