ments section of this manual).

cals which can harm rubber:

“ Avoid stumps, stones, deep ruts, sharp objects and

other hazards that may cause tire damage.

BLADE CARE

NOTE: We do not recommend sharpening blade-but if you
do, be sure the blade is balanced.

TO SHARPEN BLADE (See Fig. 14)

Care should be taken to keep the blade balanced. An
unbalanced blade will cause excessive vibration and even­
tual damage to mower and engine.

» The blade can be sharpened with a file or on a grinding

wheel. Do not attempt to sharpen while on the mower.

® To check blade balance, you will need a 5/8" diameter

steel bolt, pin, or a соле balancer. (When using a cone
balancer, follow the instructions supplied with bal­
ancer).

« Slide blade on to an unthreaded portion of the steel bolt

or pin and hold the bolt or pin parallel with the ground.
If blade is balanced, it should remain in a horizontal
position, if either end of the blade moves downward,
sharpen the heavy end until the blade is balanced.

NOTE: Do not use a nail for balancing blade. The lobes of
the center hole may appear to be centered, but are not,

cient for normal use. However, periodic charging of the
