Carburetor
Minor carburetor adjustments may be required to compensate for differences in fuel, temperature, altitude and load. To adjust carburetor, refer to the separate engine manual packed with your mower.
NOTE: A dirty air cleaner will cause an engine to run rough. Be certain air cleaner is clean and attached to the carburetor before adjusting carburetor.
WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of heated surfaces and muffler.
SECTION 7: MAINTAINING YOUR LAWN MOWER
WARNING: Be sure to disconnect and ground the spark plug wire before performing any repairs or maintenance.
Maintaining the Blade
•Periodically inspect the blade adapter for cracks, especially if you strike a foreign object. Replace when necessary.
WARNING: When removing the cutting blade for sharpening or replacement, protect hands by using heavy gloves or a rag to grasp the cutting blade.
•Remove the bolt and bell support which hold the blade and adapter to the engine crankshaft. See Figure 18 . Remove the blade and adapter from the crankshaft.

•When sharpening the blade, follow the original angle of grind as a guide. It is extremely important that each cutting edge receive an equal amount of grinding to prevent an unbalanced blade. An unbalanced blade will cause excessive vibration when rotating at high speeds, and may cause damage to the mower and/or personal injury.
•The blade can be tested by balancing it on a round shaft screwdriver. Remove metal from the heavy side until it balances evenly. It is recommended that the blade always be removed from the adapter for the best test of balance.
•Before reassembling the blade and the blade adapter to the unit, lubricate the engine crankshaft and the inner surface of the blade adapter with light oil (or engine oil). Also lubricate the bolt holes, bolts and inner surface of the nuts.
•Install the blade adapter on the crankshaft with the “star” away from the engine. Place the blade with the side marked bottom (or with part number) facing away from the adapter. Align the blade bell support over the blade with the tabs in the holes of the blade and insert the hex bolt. Tighten the hex bolt to the torque listed here.
Blade Mounting Torque:
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
•To ensure safe operation of your unit, all nuts and bolts must be checked periodically for correct tightness.
Deck Care
NOTE: We do not recommend the use of pressure washers or garden hose to clean your unit.These may cause damage to electric components, spindles, pulleys, bearings or the engine. The use of water will shorten life of the mower and reduce its serviceability.
•The underside of the mower deck should be cleaned after each use to prevent a
