WARNING: Experience indicates that
alcohol blended fuels (cailed gasohof or
using ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage_the fue! 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

MOWING TIPS
*Under certain conditions, such asvery tail
grass, itmay be necessaryto raise the
height ofcut toreduce pushing effortand to
keepfrom overloading the engine and
leavingclumps of grass clippings.
, For extremely heavy cutting, reduce the
widthof cut and raisethe rear ofthe lawn
mower housingone (1) wheel adjuster
settinghigher than the front for better
discharge ofgrass.
,, When using a rear discharge lawn mower in
moist,iteavy grass, clumps of cutgrass
may not enter the grass catcher.Reduce
ground speed (pushing speed)and/or nan
the lawn mower over the area a second
time.
o Ifatrailof grassclippings is leftonthe right
side ofa rear discharge lawn mower, mow
in aclockwise direction with a smalloverlap
to collectthe clippings on the nextpass.
, Keeptop of engine around starterclear and
clean of grassclippings and chaff.This will
helpengine airflow and extend engine life.
, Pores incloth grass catchers can become
filledwith dirt and dust with useand
catchers will collect less grass. To prevent
this, regularlyhose catchers offwith water
andletdry before using.

MULCHINGMOWINGTIPS
IMPORTANT: For best performance_
keep mower housing free of built-up grass
and trash. Clean UNDERSIDE OF
MOWER HOUSING after each use. See
"Cleaning" in CUSTOMER
RESPONSIBILITIES section of this
manual.
=The specialmulching bladewill recutthe
grass clippings manytimes andreduce
them in size so that as they fall ontothe
lawn theywiltdisperse intothe grassand
not be noticed. Also,the mulched grasswill
biodegrade quicklyto provide nutrientsfor
the lawn.Always mulch with your highest
engine (blade) speed as thiswill provide the
best recutting action ofthe blades.
,Avoid cuttingyour lawnwhen it iswet. Wet
grass tendsto form ciumps and interferes
with the mulching action.The best timeto
mow your lawn isthe early afternoon.Atthis
timethe grass has dried and the ne_,Aycut
area wiltnot be exposed tothe directsun.
,, For best results,adjust the lawnmower
cuttingheight so thatthe fawn mowercuts
off onlythe top one-thirdof the grassblades.
Ifthe lawn is overgrown itwiltbe necessary
to raisethe heightofcut to reducepushing
effort and to keep from overloading the
engine and leavingclumps of mulc_ed
grass. For extremely heavy mulching,
reduce yourwidth ofcut, mow slowlyand
raise the rear ofthe lawn mower onewheel
adjustersetting higher than the front.
o Certaintypes of grassand grassconditions
may requirethat an area be mulcheda
second time to completely hidethe
clippings.When doing a secondcut, mow
across or perpendicular tothe firstcut path.
,, Change yourcutting pattern from weekto
week. Mow north to south one weekthen
change toeast to west the'nextweek. This
will help prevent matting and grainingof the
lawn.

iMPORTANT: it isimportant to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
filter, fuel hose, or tank during storage,

which leads to separation and formation
of adds during storage. Acidic gas can
damage the fuel system of an engine
while in storage.
