WARNING: Always stop engine, discon- nect spark plug, and ground against engine before cleaning, lubricating or performing any maintenance on your machine.

Engine

Refer to the separate engine manual for engine mainte- nance instructions.

•Maintain engine oil as instructed in the separate engine manual packed with your unit. Read and follow instructions carefully.

•Service air cleaner every ten hours under normal conditions. Clean every hour under extremely dusty conditions. Poor engine performance and flooding usually indicates that the air cleaner should be serviced. To service the air cleaner, refer to the separate engine manual packed with your unit.

IMPORTANT: Never run your engine without air cleaner completely assembled.

•The spark plug should be cleaned and the gap reset every 25 hours of engine operation. Spark plug replacement is recommended at the start of each tiller season; check engine manual for correct plug type and gap specification.

•Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to permit proper air circulation which is essential to engine performance and life. Be certain to remove all dirt and combustible debris from muffler area.

Lubrication

Transmission

The transmission is pre-lubricated and sealed at the fac- tory. It requires no checking. See an authorized service dealer for any service issues.

Tine Shafts

Remove tine assemblies and lubricate the tine shafts at least once a season.

Wheel Shaft

Remove wheel assembly and lubricate the axle shaft at least once a season.

Cleaning Tine Area

Clean the underside of the tine shield after each use. The dirt washes off the tines easier if rinsed off im- mediately instead of after it dries. Always towel dry the tiller afterwards and apply a light coat of oil or silicone to prevent rusting or water damage.

IMPORTANT: Never use a “pressure washer” to clean your tiller. Water can penetrate tight areas of the tiller causing serious damage.

Replacing the Belt

Your tiller has been engineered with a belt made of special material for longer life and better performance. It should not be replaced with an off-the-shelf belt. See the retailer from which you purchased your tiller, an authorized MTD Service Dealer, or call 1-800-800-7310 for information regarding price and availability.

1.Remove the frame and engine by removing the six screws and lock nuts holding the engine and frame to the shield, Figure 6-1.
