When grinding, care should be taken to maintain
blade balance and the blade should be checked
for proper balance before reinstallation on
mower, An unbalanced or bent blade will cause
excessive vibration when running, and eventual
damage to mower or engine Replace bent or
damaged blades.
To check blade balance, drive a nail into a beam
or wall. Leave about one inch of the straight nail
exposed. Place center hole of clean blade over
the head of the nail (Fig. 13). NOTE: CENTER
HOLE OF BLADE ON NAIL, tF BLADE IS PROPER-
LY BALANCED, BLADE SHOULD REMAIN IN
POSITION SHOWN IN FIG. 13. IF EITHER END
OF THE BLADE MOVES DOWNWARD, BLADE
IS NOT BALANCED. SHARPEN THE HEAVY END
UNTIL BLADE IS BALANCED
