CARE AND MAINTENANCE
17. Sharpening the Blade
WARNING
• Always protect your hands by wearing heavy
gloves or wrapping the cutting edges with
rags or other materials when performing any
maintenance on the mower blade. Always
remove the battery pack when servicing or
transporting the mower.
• Use proper eye protection while removing,
sharpening, and installing the blade.
• A worn, cracked, or damaged blade can break,
and pieces of the damaged blade can become
dangerous projectiles. Thrown objects can
cause serious injury. Inspect the blade regularly
and do not operate the mower with a worn or damaged blade.
NOTICE: Keep the blade sharp for best mower performance. A dull blade does not cut grass
cleanly or mulch properly.
A dull blade can be sharpened, but a blade that is excessively worn, bent, cracked, or
otherwise damaged must be replaced. A worn or damaged blade can break, causing blade
pieces to be thrown from the mower.
If the blades are found to be bent, replace it.
Sharping 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 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
drop.
WARNING
• An unbalanced blade will cause excessive vibration when rotating at high speeds. It may
cause damage to the mower and could break, causing personal injury.
