BLADE CARE
For
best
results mower blades
must be kept
sharp. The blacles
can
be sharpened
with
a
few strokes
of
a file
or on
a
grinding
wheel. We suggest
they be
sharpened after every 15 hours of
mowing.
Do
not attempt to
sharpen
while on mower.
1. When
grinding,
care should be
taken
t
o maintain
blade
bal·
ance and the blade should be
checked for
proper
balance
before reinstallation
on
mower.
Unbalanced or bent blade
will cause excessive vibration when
running, and eventual
damage
to mower or engine.
Replace bent, damaged or un-
balanced
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.
22).
NOTE:
CENTER HOLE OF
BLADE
ON NAIL. IF
BLADE IS
PROPERLY
BALANCED,
BLADE SHOULD
REMAIN IN POSITION
SHOWN IN
FIG. 22. IF
EITHER
END OF THE BLADE MOVES DOWNWARD, BLADE
IS
NOT BALANCED AND
MUST
BE REPLACED.
2. To ensure
satisfactory
operation,
it
is
recommended
that
before the start
of each
mowing season, the
old blades
be
discarded and
replaced with new
blades.
Mower blades
can
be purchased
at any Sears
Service
Center/Departments
and
most
Sears
Retail Stores.
