WARNING: Experience indicates that alcohol blend-
ed 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 for 30 days or longer_ Drain
the gas tank, start the engine and let it run until the

tempting to start and DO NO1" repeat priming steps_

I IOW G T PS

Under certain conditions, such as very tall grass,
it may be necessary to raise the height of cut and
lower the ground speed to keep from overloading
the engine and leaving clumps of grass dippings_

For extremely heavy cutting, reduce the width of
cut and raise the lawn mower housing one (1) set-
ting higher for better discharge of grass.

o 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 ove_"

the area a second time.

o _fa trail of grassdippings is left on the right side

of a rear discharge lawn mower, mow in a
clockwise direction with a small overlap to col-
le_:t the clippings on the next pass

o Pores in cloth grass catchers can become filled

with dirt and dust with use and catchers wil! col-

led less grass. To prevent this, regularly hose cat-
cher off with water and let dry before using.

Ibs_

o Torque wrenches are available at most Sears

AND MAY MAKE THE ENGINE HARD TO START. II ....................

Use only a Sears authorized replacement Btade to
get the best cutting results.
NOTE: We do not recommend sharpening Blade - but
if you do, be sure the Blade is balance&

TO SHARPEN BLADE:

o The Blade can be sharpened with a file or on a

grinding wheel_ Do not attempt to sharpen while
on the lawn mower_

o Care should be taken to keep the Blade balanc-

ed. An unbalanced Blade will cause excessive
vibration when running and eventual damage to

lawn mower or engine_

o 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, Blade is not balanced.
Sharpen the heavy end until the Blade

balanced.
