MOWING TIPS
• Under certain conditions, such asvery tallgrass, itmay
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 thewidth ofcut by
overlapping previousiy cut path and mow slowly
• For better grass bagging and most cutting conditions,
the engine speed should be set in the fast (_4_) posi-
tion.
• 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 runthe lawn mower over thearea asecond time
. If a trail of clippings is left on the right side of a rear
discharge mower, mow in a clockwise direction with a
small overlap tocollect 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 ctear and clean of
grass clippings andchaff This will help engine air flow
and extend engine life

MULCHING MOWING TIPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH, SEE "CLEANING" iN CUSTOMER
RESPONStB{LITIES SECTION OF THiS MANUAL
• The special mulching blade will recut the grass clip-
pings many times and reduce them in size so that as
theyfall 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 iswet Wet grass tends
toform clumps and intederes with the mulching action.
The best timeto 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 lawnmower cuts off only the top one-third
of the grass blades (See Fig. 11) ff the lawn is
overgrown itwill be necessary to raise the height ofcut
to reduce pushing effort and to keep from overloading
the engine and leavingclumps of mulched grass. For
extremely heavy mulching, reduce your width of cut by
overlapping previously cut path and mow slowly.
. Certain types of grass and grass conditions may re-
quire 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 toweek. Mow
north to south one week thenchange toeast towest the
next week This will help prevent matting and graining
of the lawn..

FUEL SYSTEM
iMPORTANT: iT IS IMPORTANT TO PREVENT GUM
DEPOSITS FROM FORMING IN ESSENTIAL FUEL
SYSTEM PARTS SUCHAS CARBURETOR, FUEL FILTER,
FUEL HOSE, OR TANK DURING STORAGE. ALSO,
EXPERIENCE INDICATES THAT ALCOHOL BLENDED
FUELS (CALLED GASOHOL OR USING ETHANOL OR
METHANOL) CAN ATTRACT MOISTURE WHICH LEADS
TO SEPARATION AND FORMATION OF ACIDS DURING
STORAGE, ACIDIC GAS CAN DAMAGE THE FUEL
SYSTEM OF AN ENGINE WHILE tN STORAGE
• Drain the fuel tank
• Start the engine and let it run until the fuel lines and
carburetor are empty,
• Never use engine orcarburetor cleaner products in the
fuel tank or permanent damage may occur,
• Use fresh fuel next season,
NOTE: Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during stor-
age. Add stabilizer to gasoline in fuel tank or storage
container, Always follow the mix ratio found on stabilizer
container. Run engine at least t0 minutes after adding
stabilizer to allow the stabilizer to reach the carburetor. Do
not drain thegas tank and carburetor if using fuel stabilizer
