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.
