MOWING TIPS
Under certain conditions, such as very tall grass,
it may be necessary to raise the height of cut to re-
duce pushing effort and to keep from overloading the
engine and leaving clumps of grass clippings. It may
also be necessary to reduce ground speed and /or
run the lawn mower over the area a second time.
For extremely heavy cutting, reduce the width of
cut by overlapping previously cut path and mow slowly.
For better grass bagging and most cutting condi
tions, the engine speed should be set in the fast position.
Pores in cloth grass catchers can become filled
with dirt and dust with use and catchers will collect
less grass. To prevent this, regularly hose catcher off
with water and let dry before using.
Keep top of engine around starter clear and clean
of grass clippings and chaff. This will help engine air
flow and extend engine life.

TO SHARPEN BLADE
NOTE:
We do not recommend sharpening blade but
if you do, be sure the blade is balanced.
Care should be taken to keep the blade balanced.An
unbalanced blade will cause eventual damage to lawn
mower or 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, drive a nail into a beam
or wall. Leave about one inch of the straight nail
exposed. Place center hole of blade over the head
of the nail. If blade is balanced, it should remain in
a horizontal position. If either ends of the blade moves
downward, sharpen the heavy end until the blade is
balanced.
GRASS CATCHER
The grass catcher may be hosed with water, but
must be dry when used.
Check your grass catcher often for damage or
deterioration. Through normal use it will wear. If
catcher needs replacing,replace only with a manu-
facturer approved replacement catcher.Give the
lawn mower model number when ordering.
