otherwise damaged must be replaced. A worn or damaged blade can break, causing
blade pieces to be thrown from the mower.
If the blade is found to be bent, take the lawn mower to an authorized EGO service
center for inspection.
Sharpening Frequency
Sharpening the blade twice during a mowing season is usually sufficient under normal
circumstances. Sand causes the blade to dull quickly; if your lawn has sandy soil, more
frequent sharpening may be required.
When Sharpening the Blade:
◾
Make sure that the blade remains balanced.
◾
Sharpen the blade at the original cutting angle.
◾
Sharpen the cutting edges on both
ends of the blade, removing an equal
amount of material from each end.
To Sharpen a Blade in a Vise:
1. Remove the blade from the mower.
2. Secure the blade in a vise (Fig. 19a).
3. Wear proper eye protection and
gloves and be careful not to cut
yourself.
4. Carefully file the cutting edges of
the blade with a fine-tooth file or
sharpening stone, maintaining the
original cutting edge angle.
5. To check the blade balance: clamp
a nail or a screwdriver with a round
shank in the horizontal position.
Position the blade so that the nail
or round shank of the screwdriver supports the blade through its center hole.
Balance the blade horizontally. If either end of the blade rotates downward,
remove some metal from the heavy or lower end until the blade is balanced. It is
balanced when neither end drops (Fig. 19b).
