Blade Care
When removing the cutting blade for sharpening or replacement, protect
your hands with a pair of heavy gloves or use a heavy rag to hold the blade.
Periodically inspect the blade adapter for cracks, especially if you strike a foreign
object. Replace when necessary. Follow the steps below for blade service.
1.
Allow the engine to run until it is out of fuel. Do not attempt to pour fuel
from the engine. Disconnect spark plug wire. Refer to Engine Operator's
Manual.
2.
Turn mower on its side making sure that the air filter and the carburetor are
facing up.
3.
Remove the bolt and the blade bell support which hold the blade and the
blade adapter to the engine crankshaft. See Figure 16.
4.
Remove blade and adapter from the crankshaft.
5.
Remove blade from the adapter for testing balance. Balance the blade on a
round shaft screwdriver to check. Remove metal from the heavy side until
it balances evenly. When sharpening the blade, follow the original angle of
grind. Grind each cutting edge equally to keep the blade balanced.
An unbalanced blade will cause excessive vibration when rotating at high
speeds. It may cause damage to mower and could break causing personal
injury.
6.
Lubricate the engine crankshaft and the inner surface of the blade adapter
with light oil. Slide the blade adapter onto the engine crankshaft. Place the
blade on the adapter such that the side of the blade marked "Grass Side"
(or with part number) faces the ground when the mower is in the operating
position. Make sure that the blade is aligned and seated on the blade adapter
flanges. See Figure 16 inset.
