Blade Care
Periodically inspect the blade adapter and pulley for
cracks, especially if you strike a foreign object. Replace
when necessary.
• Disconnect spark plug wire from spark plug.
• Turn mower on its side making sure that the air filter
and the carburetor are up.
To Remove Blade:
• Remove the bolt and bell washer which hold the
blade-pulley assembly to the engine crankshaft.
See Figure 12 .
Figure 12
• Remove the blade-pulley assembly from the
crankshaft.
• Remove the two bolts and lock nuts from the blade
assembly. See Figure 12 .
• Remove the blade from the blade adapter and
pulley.
To Replace Blade:
• Before reinstalling the blade-pulley assembly 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, bolt and the inner
surface of the nuts.
• Install the blade adapter on the pulley with the “star”
away from the pulley. See Figure 12 .
• Place the new blade on the blade adapter with the
side marked bottom (or with part number) facing
away from the adapter.
• Secure the blade to the assembly with two hex
bolts and lock nuts. Tighten the hex bolts to the
recommended torque. Refer to ‘Blade Mounting
Torque’ section on next page.
• Install the blade assembly on the crankshaft.
Secure with the hex bolt and bell washer (cupped
side of washer to blade) and tighten to the
recommended torque. Refer to ‘Blade Mounting
Torque’ section on next page.
IMPORTANT:
The bolt used to secure the blade to the
engine is specially heat-treated. Do not substitute. To
order replacement bolt, refer to the parts list in the back
of this manual.
To Sharpen Blade:
• The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen the
blade while it is still on the mower.
• Follow the original angle of grind as a guide. Make
sure 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, may cause
damage to the mower and could break, causing
personal injury. Test the blade by balancing it on a
round shaft screwdriver or a blade balancer.
• If the blade is not balanced, remove metal from the
heavy side until it balances evenly.
WARNING: When removing the cutting
blade for sharpening or replacement, protect
hands by using heavy gloves or a thick rag to
grasp the cutting blade.
