Tools & supplies needed:
14 mm socket wrench (supplied with Mower)
Gloves or rag to protect your hands
Wear heavy gloves to protect your hands when holding, removing and attaching blades.
1. Remove the safety key from it's socket, and remove battery. If you are charging the battery, first
disconnect the charger from the electrical (wall) outlet.
2. While holding the handle bars, turn the Mower over on its right side to expose the blade.
3. Place the socket wrench over the blade nut.
4. While holding the blade in place, loosen the blade nut by turning counterclockwise. Be careful; wear
heavy gloves to hold the blade in place so the blade does not spin and strike your hand (see Figure 17).
5. Remove the blade nut,plastic spacer and blade in that order (see Figure 18).
6. To install a new or sharpened blade, reverse steps 1 to 5. Be sure to replace all parts in order exactly as
they were removed. Make sure the blade is properly seated and securely tightened.
7. Turn your mower upright.
Sharpening the Blade
When the blade is dull, the cut ends of the grass will be ragged and may turn brown soon after mowing. A
dull blade also causes the battery to discharge more quickly. When this occurs, sharpen the blade.
Important: You must remove the blade from the mower to sharpen it.
Tools & supplies needed:
Fine-toothed file or sharpening stone
Gloves.
Safety glasses
Sharpening the Blade in a Vice
1. Remove safety key from it's socket, and remove battery.
2. While holding the handlebars, turn the mower over on its right side to expose the blade.
3. Remove the blade.
4. Secure the blade in a sturdy vice.
5. While wearing safety glasses, carefully file the cutting edges of the blade using even strokes. Be sure to
file both sides of the blade equally.
6. Check the blade after sharpening to be sure it is still balanced.
Balancing the Blade
Attention! When sharpening a used blade, be especially careful to keep it balanced. If in doubt,
replace the blade with a new one.
An out-of-balance blade causes your machine to vibrate excessively. Excessive vibration may cause
damage to the Mower, especially to its motor.
Because you are removing metal from the blade, make sure to remove an equal amount from each side to
keep the blade balanced.
If unsure, you can always have a mower service shop sharpen and balance your blade.
