56-VOLT LITHIUM-ION CORDLESS LAWN MOWER — LM2110/LM2110-FC/LM2110SP/LM2110SP-FC/LM2120SP/LM2120SP-FC 43
TO SHARPEN BLADE IN A VISE:
1. Remove the blade from the mower
(please see "REMOVING THE
BLADE").
2. Secure the blade in a vise (Fig. 26).
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 screw driver 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. 27).
6. Replace the blade on the mower and tighten it securely (please see "INSTALLING
THE BLADE").
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.
