NOTE: 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. See Figure 14. 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.
1.Insert screw driver through hole
2.Blade should be parallel to ground

•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. Refer to Figure 13. 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 in the “Blade Mounting Torque” section below.
Blade Mounting Torque
Center Bolt: 450 in. lbs. min., 600 in. lbs. max.
IMPORTANT:To ensure safe operation, 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 buildup of grass clippings, leaves, dirt or other matter. If this debris is allowed to accumulate, it will invite rust and corrosion, and may cause an uneven discharge of grass clippings at the next cutting.
•The deck may be cleaned by tilting the mower and scraping clean with a suitable tool (make certain the spark plug wire is disconnected).
Engine
•Refer to the separate engine manual.
Lubrication
(Refer to Lubrication Chart in Figure 15.)
WARNING: Always stop engine and disconnect spark plug wire before cleaning, lubricating or doing any kind of work on lawn mower.

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.
Rear & Side Discharge Doors
•The torsion springs and pivot points should be lubricated periodically with light oil to prevent any rust or binding. Door must work freely.
Wheels
•The wheels require no lubrication. However, if the wheels are removed for any reason, lubricate the surface of the axle bolt and the inner surface of the wheel with light oil. Engine oil may also be used.
Engine
•Follow engine manual for instruction and schedule of lubrication.
NOTE: When tipping the unit, empty the fuel tank and keep engine spark plug side up.
