NOTE: To seal tire punctures and prevent flat tires due to slow leaks, tire sealant may be purchased from your local parts dealer. Tire sealant also prevents tire dry rot and

corrosion.

TO SHARPEN BLADE

NOTE: We do not recommend sharpening

blade - but if you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced. An unbalanced blade will cause

excessive vibration and eventual damage to mower and engine.

•The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.
