A
WARNING: Be sure to disconnect and
ground the spark piug wire and remove ig­
nition key before working on the cutting
biade to prevent accidentai engine start­
ing. Protect hands by using heavy gioves
or a rag to grasp the cutting biades.
1. Remove the large bolt and lock washer which holds
the blade and adapter to the blade spindle.
2. Remove the blade and adapter from the spindle.
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 directions
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.
The 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.
C. Reassembly
Before reassembling the blade and the blade adapter
to the unit, lubricate the spindle and the inner surface
