SIX SPEED SHIFT CABLE ADJUSTMENT

Periodic adjustment of the six speed shift ca- ble may be required due to normal stretch and wear on the cable. Adjustment is needed if all six speeds cannot be obtained.

The adjustable cable bracket is located on the left side of the mower, beside the en- gine. To adjust, loosen the hex nut which secures the adjustable cable bracket. See Figure 17. Pull backward on the bracket (to- ward the rear of the mower). Retighten the hex nut. Test the speeds on the mower (en- gine must be running).

CARBURETOR ADJUSTMENT

Refer to the separate engine manual packed with your mower for carburetor adjustment information.

LUBRICATION

CAUTION: DISCONNECT SPARK PLUG WIRE BEFORE SERVICING.

WHEELS - If your mower is equipped with ball bearing wheels, lubricate at least once a season with a light oil, all other types require no lubrication. However, if the wheels are re- moved for any reason, lubricate the surface of the axle bolt and the inner surface of the wheel with light automotive oil.

ENGINE - Follow engine manual for lubrication instructions.

BLADE CONTROL - Lubricate the pivot points on the blade control handle and the brake cable at least once a season with light oil. The blade control must operate freely in both directions.

TRANSMISSION - The transmission is pre-lubricated and sealed at the factory. It does not require checking. If disassembled for any reason, fill with 2 ounces of Alvania grease, part number 737-0168.

MAINTENANCE

For best results your blade should be sharp. The blade may be resharpened by removing it and either grinding or filing the cutting edge keeping as close to the original bevel as possible.

Improper blade balance will result in exces- sive vibration causing eventual damage to the engine and mower. Be sure to carefully balance blade after sharpening.

After prolonged use, especially in sandy soil conditions, the blade will become worn and lose some of the original shape. Cutting effi- ciency will be reduced and the blade should be replaced. Replace with an approved factory replacement blade only. Possible damage re- sulting from blade unbalance condition is not the responsibility of the manufacturer.

ENGINE

Refer to the separate engine manual for en- gine maintenance instructions.

Maintain engine oil as instructed in the sepa- rate engine manual packed with your unit. Read and follow instructions carefully.

Under normal conditions service air cleaner as instructed in the separate engine manual packed with your unit. Clean every few hours under extremely dusty conditions. Poor engine performance and flooding usu- ally indicates that the air cleaner should be serviced.

The spark plug should be cleaned and the gap reset once a season. Spark plug replace- ment is recommended at the start of each mowing season; check engine manual for cor- rect plug type and gap specifications.
