MOWING TIPS

•• Under certain conditions, such as ver_
tall grass, it may be necessary to raise

the height of cut to reduce pushing
effort and to keep from overloading thq
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 tt

width of cut by overlapping previously

cut path and mow slowly.

• For better grass bagging and most

cutting conditions, the engine speed
should be set in the fast position.

• For side discharge lawn mowers,

cutting in a counter-clockwise directio
starting at the outside of the area to b_
cut, spreads grass clippings more

evenly and puts less load on the
engine. To keep clippings off of

walkways, flower beds, etc., make the

first cuts in a clockwise direction.

• Pores in cloth grass catchers can
become filled with dirt and dust with

use and catchers will collect less gras
To prevent this, regularly hose catche
off with water and let dry before using

• Keep top of engine around starter cle

and clean of grass clippings and chaf
This will help engine air flow and

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, itshould remain in
a horizontal position. If either end of the
blade moves downward, sharpen the

heavy end untilthe blade is balanced.

adjusting, contact your nearest authorized
service center, which has proper equip-

ment and experience to make any

necessary adjustments.
CARBURETOR

mainjet for mixture control. If your engine

does not operate properly due to sus-

pected carburetor problems, take your
lawn mower to an authorized service

center for repair and/or adjustment.

ENGINE
FUELSYSTEM
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. Also, experience
indicates that alcohol blended fuels (called

gasohol or using ethanol or methanol) can
attract moisture which leads to separ'_on and

formation of acids during storage. Ac'_licgas
can damage the fuel system of an engine

while in storage.

• Drain the fuel tank.

• Start the engine and let it run untilthe fuel

lines and carburetor are empty.

• Never use engine or carburetor cleaner
products in the fuel tank or permanent

damage may occur.

• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable
aitemative in minimizing the formation of fuel

gum deposits during storage. Add stabilizer
to gasoline in fuel tank or storage container.

Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes

after adding stabilizer to allow the stabilizer to

reach the carburetor. Do notdrain the gas

tank and carburetor if using fuel stabilizer.

ENGINEOIL
Drain oil (with engine warm) and replace with

clean engine oil. (See "ENGINE" in the
Maintenance section of this manual).

CYUNDER

• Pourone ounce(29 mi) of oilthrough spark

plughole intocylinder.

• Pullstarterhandle slowlya few timesto
