MAINTENANCE

When sharpening, care should be taken to keep the blade balanced. An unbalanced blade

will cause excessive vibra-tion when the mower is running. This vibration will eventually

cause damage to the mower, especially the motor.

To check the blade balance:

■ Clamp a screwdriver horizontally in a vise as shown.

NOTE: If a vise is not available, a straight nail can also be used.

■ Place the center hole of blade on the screwdriver (or nail) shank.

■ If blade is balanced, it will remain in a horizontal position. If either end of the blade drops

downward, sharpen the heavy side until the blade is balanced.
