AWARNING: Expedenoe 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 in storage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the gas tank, start the
engine and let it run until the 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 the fuel

MOWINGTIPS
• Under certainconditions,such as very
tall grass, it may be necessary to raise
the height of Cutto reduce pushing
effort and to keep from overloadingthe
engine and leaving clumps of grass
clippings. It may also be necessary to
reduce ground speed and/or run the
lawn mower over the area a second
time.
• For extremely heavy cutting,reduce the
width of cut by ovedapping previously
cut path and mow slowly.
• For better grass bagging and most
cuttingconditions, the engine speed
shouldbe set in the fast 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 clippingsis left on the right
side of a rear discharge mower, mow in
a clockwise directionwith e small
ovedap to collectthe clippingson 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,
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean UNDERSIDE OF MOWER
HOUSING after each use. See "Cleaning"

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 grindingwheel. 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.
Crankshaft
NOTE: Although multi--viscosity oils
(5W30, 10W30 etc.) improve startingin
cold weather, these multi--viscosity oils
will 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
Change the oilafter every 25 hoursof
operation or at least once a year if the
lawn mower is not used for 25 hours in
one year.
