Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) carl
attract moistu re which leads to separation and formation of
acids during storage_ Acidic gas can damage the fuel
system of an engine while in storage_ To avoid engine
problems, the fuel system should be emptied before storage of 30 days or longer, Drain the fuel tank, start the
engine and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season,, See Storage Instructions for additional information,
Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur,,

TO START ENGINE
•

To start a cold engine, push primer five (5) times before
trying to start, Use a firm push, This step is not usually

NOTE: In cooler weather it may be necessary to repeat
priming steps,, in warmer weather' over' priming may cause
flooding and engine will not start, If you do flood enginewait
a few minutes before attempting to start and do not repeat
priming steps,

OPERATION
MOWING
o

T PS

Under certain conditions, such as very tall grass, it may
be necessary to raise the height of cut to reduce
pushing effort and to keep from overloading the engine
and leaving clumps of grass clippings..

For extremely 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,

For better grass bagging and most cutting conditions,
the engine speed should be set in the high (,1_)
position..

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 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.,

RESPONSIBILITIES
SECTION OF THIS MANUAL

The special mulching blade will recut the grass clippings many times and reduce them in size so that as
they fall onto the lawn they wilt disperse into the grass
and not be noticed., Also, the mulched grass will
biodegrade quickly to provide nutrients for the fawn,
Always mulch with your highest engine (blade) speed
as this wil! provide the best recutting action of the
blades.,

Avoid cutting your lawn when it is wet., Wet grass tends
to form clumps and interferes with the mulching action.
The best time to mow your lawn is the early afternoon.
At this time the grass has dried and the newly cut area
will not be exposed to the direct sun.,

•

For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig., 13), If the lawn is
overgrown it will be necessary to raise the height of 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 than the front..

•

Certain types of grass and grass 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.,

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,.

improve starting in cold weather, these mufti-viscosity oils
wili result in increased oil consumption when used above
32°F, Check your engine oil level more frequently to avoid
possible engine damage from running low on oil,

AIR FILTER COVER

Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the lawn
