To Sharpen Blade:
• The blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen the
blade while it is still on the mower.
• Follow the original angle of grind as a guide. Make
sure that each cutting edge receives an equal
amount of grinding to prevent an unbalanced blade.
NOTE: An unbalanced blade will cause excessive
vibration when rotating at high speeds, may cause
damage to the mower and could break causing
personal injury.
• The blade can be tested by balancing it on a round
shaft screwdriver. See Figure 18. Remove metal
from the heavy side until it balances evenly. It is
recommended that the blade always be removed
from the adapter for the best test of balance.
