ENGINE

Refer to the separate engine manual for engine maintenance instructions.

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

instructions carefully.

• Service air cleaner  every 25 hours under normal conditions. Clean every few hours 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.

• The spark plug should be cleaned and the gap reset once a season. Spark plug replacement is recommended

at the start of each mowing season; check engine manual for correct plug type and gap specifications.

• 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 grass,
dirt and combustible debris from muffler area.

BELT REPLACEMENT

Disconnect the spark plug wire and ground it against the engine.

• Drain the fuel tank or place a piece of plastic beneath the cap to prevent gasoline leakage.

• Remove the transmission belt cover by removing the three bolts. See Figure 15.

• Tip the mower back on its side with the air filter side away from the ground. Block securely.

Figure 15  

• Remove the center bolt which secures the blade to the crankshaft. See Figure 14.

• Remove the blade bell support, the blade, and the blade adapter, and the pulley half. See Figure 13. Remove

the belt. 

• Using a 3/8” wrench, remove the two self-tapping screws which hold the inside belt cover, and remove the

cover. See Figure 15. 

• Remove the belt from between the idler pulley and the belt guard on the idler pulley bracket. 

• Remove the belt from the transmission pulley.

• Push the idler pulley up and out of the way. See Figure 16.
