BEFORE STARTING ENGINE
OIL
Your lawn mower is shippedwithoutoil inthe
engine.
• Be sure mower is level and area around oil
fill is dean.
• Remove engineoil cap and fillto the _11
line on the dil_Ck.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.
• Engineholds 27 ozs. of oil. For type and
grade of oilto use, see "ENGINE" in
Maintenance sectionof this rnadual.
• Pour oil slowly. Do not over fill.
• Check oil level before each use. Adcloilif

• Reinstallengine oil cap and tighten,
• Change the oilafter overy 25 hoursof
operationor each season. You may need
to change the oil more often underdusty,
dirty conditions.

GAS
• RII fuel tank. Use fresh, dean, regular
unleaded gasolinewith a minimum of 87
octane. (Use of leaded gasolinewill
increase carbon and lead oxide deposits
and raduce valve life). Do not mix oil with
gasoline. Purchasefuel in quantitiesthat
can be usedwithin 30 days to assure fuel
frashnees.
_WARNING:
Ex_'.ence indicatesthat
alcoholblended fu_;is(called gasohol or
usingethanol or methanol) can attract
moisture which leads to seperationand
formation of acids duringstorage. Acidicgas
can damage the fuel systemof an engine
while in storage. To avoid engine problems,
the fuel system should be emptied before
storage of 30 days or longer. Drain the gas
tank, startthe engine and let it run until the

MOWING TIPS
• For most cuttingconditionsand better
bagging performance,the engine speed
shouldbe set in the fast position.
• Undar certain cenditJorts,such as when
mowing very tall grass, raisethe mower
heighton the firstcutto reduce pushing
effort,to avoid overheatingthe engine, and
to avoid leaving dumps of grass clippings.
Make the secondcutto the desiredheight.
• For exb'emelyheavy cutting,reduce the
w_h of cut.
• Pores in cloth grass catcherscan become
filledwithdirtand dustwithuse and the
catcherwillcollectless grass. To prevent
this, regularlyhose catcher offwith water
and let dry before use.
MULCHING MOWING TIPS
IMPORTANT: For best performance,keep
mower housingfree of built-upgrass and
bash. See "Cleaning" in MAINTENANCE
sectionof this manual.
• The special mulchingblade will recutthe
grass clippingsmany times and reduce
them in size so that as they fallontothe
lawn they will disperseintothe grass and
not be noticed, Also, the mulchedgrass
will
biodegradequicklyto providenubients
for the lawn. Always mulchwithyour
highestengine (blade) speed as this will
providethe best recuttingactionof the
blades.
• Avoid cutting your lawn when it is wet. Wet
grass tends to form dumps and interferes
with the mulching action. The best time to
mow your lawn is the early afternoon. At
this time the grass has driedand the newly
cutarea willnot be exposed to the direct
SUn.
• For best results,adjustthe lawn mower
cuttingheight so that the lawn mower cuts
off onlythe top one-thirdof the grass
blades. If the lawn is overgrownitwillbe
necessaryto raisethe heightof cutto
reduce pushingeffortand to keep from
overloadingthe engine and leaving
clumpsof mulchedgrass. For extremely
heavy mulching,reduceyour width of cut
by overlappingpreviouslycut pa_ _md
moo slowly.
• Certain typesof grass and grass cond_ons
may requirethat an area be mulcheda
secondtime to completelyhidethe
clippings. When doing a second cut, mow
acrossor perpendicularto the tirstcutpath.
• Change your cuttingpattemfmmweekto
week. Mow northto southone weak than
change to east to westthe nextweak. This
willhelp prevent matting and grainingof
the lawn.

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 end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
