CUTTING BLADE
A. Removal for Sharpening or Replacemer t
A ^ WARNING I
Be sure to disconnect and ground
the spark plug wire before working
on the cutting blade to prevent
accidental engine starting.
Remove the large bolt and lock washer which
holds the blade and adapter to the engine
crankshaft. See figure 17. Remove the blade and
adapter from the crankshaft.
If the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and nuts
which hold the blade to the adapter.
A
CAUTION
Periodically inspect the blade adapt­
er for cracks, especially if you strike
a foreign object. Replace when nec­
essary.
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
unblanced blade will cause excessive vibration
when rotating at high speeds, may cause damage
to
the mower and could break, causing personal
injury.
It is recommended that the blade always be
removed from the adapter for the best test of
balance. The blade can be tested by balancing it
on a round shaft screwdriver. Remove metal from
the heavy side until it balances evenly.
C. Reassembly
Before reassembling the blade and the blade
adapter to the unit, lubricate the engine
crankshaft and the inner surface of the blade
adapter with light oil. Lubricating the bolt holes,
bolts and inner surface of the nuts with light oil is
also recommended. A 4 oz. plastic bottle of light
oil
lubricant is available. Order part number
737-0170. Engine oil may also be used.
