Figure 17: Lubrication Chart
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.
Blade Care
•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 blade support or bell washer 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 receives an equal amount of grinding to prevent an unbalanced blade.
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 19. 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.
