Lubrication, Maintenance, Carburetor Adjustment

To adjust the tension on the belt, refer to clutch adjustment information in “Checking the Clutch Adjustment” section of the Assembly Instructions. After belt tension has been adjusted, if the belt is excessively stretched, you may need to adjust the idler pulley rod. This can easily be checked. With the engine off and the clutch control bail disengaged, shift the gear selection handle to each forward mode. If the indicator bracket touches the idler pulley rod, (with the clutch control bail disengaged), then an adjustment is necessary.

1.Disconnect and ground out spark plug wire against the engine.

2.Remove the belt cover as described in the belt replacement section on page 12.

3.Remove the hairpin clip and flat washer from the idler pulley rod. See Figure 12.

4.Move the idler pulley rod to the lower hole in the idler bracket. See Figure 12.

5.Replace the wave washer and hairpin clip.

6.Check clearance of the idler pulley rod to the indicator bracket by shifting to each forward mode, as before.

CARBURETOR ADJUSTMENT

WARNING: If any adjustments are made to the engine while the engine is running, (e.g. carburetor), disengage all clutches and tines. Keep clear of all moving parts. Be careful of heated surfaces and muffler.

Never make unnecessary adjustments. The factory settings are correct for most applications. If adjustments are needed, refer to the separate engine manual packed with your tiller.

SECTION 10: LUBRICATION

Transmission—The transmission is pre-lubricated and sealed at the factory. It requires no checking unless the transmission is disassembled. To fill with grease, lay the right half of the transmission on its side. Add 30 ounces of Benalene 920 grease. Apply a bead of RTV or silicone sealant to the right half of the transmission, all the way around the gear compartment. Assemble the left half to it. This grease can be obtained at your nearest authorized dealer. Order part number 737-0300.

Clutch Bail—Lubricate the pivot point on the clutch bail and the cable at least once a season with light oil. The control must operate freely in both directions.

Pivot Points—Lubricate all pivot points and linkages at least once a season with light oil.

Tine Shaft—Remove tines at least once a season and lubricate with oil.

Wheel Axle—Remove the wheel assemblies at least once a season and lubricate with oil.

SECTION 11: MAINTENANCE

WARNING: Disconnect the spark plug wire and ground it against the engine before performing any repairs or maintenance.

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 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.

CLEANING THE TINE AREA

Clean the underside of the tine shield after each use. The dirt washes off the tines easier if washed off immediately instead of after it dries.
