4. Place the ¾ inch socket wrench over the blade
nut.
5. While holding the steel hex adapter in place,
loosen the blade nut by turning
counterclockwise. Be careful; hold the steel
hex adapter in place so the blade does not spin
and strike your hand (Figure 30).
6. Remove the blade nut, steel hex adapter, blade,
plastic spacer, and steel blade adapter, in that
order (Figure 31).
7. To replace a sharpened blade or to install a
new blade, reverse steps 1 to 6. Be sure to
replace all parts exactly as they were removed.
Make sure the blade is properly seated.
8. Place the 36 mm wrench over the steel hex adapter, then place the ¾ inch socket wrench over
the blade nut.
9. While holding the steel hex adapter in place,
tighten the blade nut by turning clockwise.
Make sure the blade is firmly attached to the
Mower.
10. 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 (as long as the blade is
otherwise in good condition).
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
Vise
1. Remove the safety key and the battery.
2. While holding the handlebars (as if you are mowing), turn the Mower over on its right side to
expose the blade.
