CUTTING BLADE A. Removal for Sharpening or Replacement
t WARNING:
.~ Be sure to disconnect and ground
the spark plug wire and remove
ignition key before working on the
cutting blade to prevent accidentalengine
starting.
1. Remove the large bolt and lock washer which holds the blade and adapter to the blade spin-
dle.2.
Remove the blade and adapter from the spin-
dle. Be careful not to lose the key on the spin-
dle.3.
If the blade or blade adapter needs replacing, remove the two small bolts, lock washers and nuts which hold the blade to the adapter.
B. Sharpening Remove the cutting blade by following the direc-
tions of the preceding section. When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receives an equal amount
of grinding to prevent an unbalanced blade. An un­balanced blade will cause excessive vibration when rotating at high speeds, may cause damage to the mower and could break, causing personal
injury.
blade can be tested for balance by balancing
it on a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly.
NOTE
It is recommended that the blade always be removed from the adapter for the best test of balance.
Reassembly
Before reassembling the blade and the blade adapter to the unit, lubricate the spindle and the inner surface of the blade adapter with light oil. Lubricating the bolt holes, bolts and inner surface
