can attract moisture which leads to separation and
formation of acids during storage. Acidic gas can
damage the fuel system of an engine wMe in storage.
To avoid engine problems, the fuel system should be
emptied before storage for 30 days or longer'. Drain
the gas tank, start the engine and let it run until the

o Under certain conditions, such as very tait grass,
it may be necessary to raise the height of cut to
reduce pushing effort
and to keep from
overloading the engine and leaving dumps of
grass clippings°
o For extreme{y heavy cutting, reduce the width of
cut and raise the rear of the lawn mower housing one (1) wheel adjuster setting higher than the
front for better discharge of grass.
o When using a rear discharge lawn mower in
moist, heavy grass, clumps of cut grass may not
enter the grass catcher_ Reduce ground speed
(pushing speed) and/or run the lawn mower over
the area a second time_
• if a trail of grass clippings is left on the right side
of a rear discharge lawn mower, mow in a
clockwise direction with a small overlap to collect the clippings on the next pass.
_. 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 catchers off
with water and let dry before using.

FIG. 10
MULCHING MOWING TIPS
The special mulching Blade will recut the grass
clippings many times and reduce them in size so
that ast-heyfal(onto the lawn they will disperse into
the grass and not be noticed. Also, the mulched
grass will biodegrade quickly to provide nutrients
for the lawn. Always mulch with your highest
engine (blade) speed as this will provide the best
recurring action of the blades.
Avoid cutting your lawn when it is wet, Wet grass
tends to form clumpsand mterteres w|th the mulching action. The best time to mow your lawn is the
early afternoon. At this t!me the grass has dried
and the newly cut area w_ll not be exposed to the
direct sun.
11
o
For best results, adjust the lawn mower cutting
height so that the lawn mover cuts off only the top
one-third of the grass blades (See Fig. 10). If the
!awn is overgrown it will be necessary to raise the
height ot cut to reduce pushing effort and to keep.
from overloading the engine and leaving clumps of
mulched grass. For extremely heavy mulching,
reduce your width of cut, mow slowly and raise
the rear of the lawn mower one wheel adjuster
setting higher thanthe front.
o
Certain types of grass and qrass conditions may
require that an area be mulched a second time to
completely hide the clippings. When doing a
second cut, mow across or perpendicular to the first
cut path.
o
Change your cutting pattern from week to week.
Mow north to south one week then change to east
to west the next week. This will help prevent
matting and graining of the lawn.

• 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 nailo If blade is balanced, it should remain
in a horizontal position° If either end of the blade
moves downward,
blade is not balanced,
Sharpen the heavy end until the blade is

Turn lawn mower on its side with carburetor up
Clean the underside of your' lawn mower by
scraping to remove build-up of grass and trash.
Clean your lawn mower and engine often to keep
trash from accumulating around engine. A clogged engine runs hotter and shortens engine life.
We DO NOT recommend using a garden hose
to clean lawn mower unless the electrical system,
muffbr, air filter, and carburetor are covered to
keep water out. Water in engine can result in
shortening engine life,
