OPERATION

HOW TO USE YOUR LAWN MOWER

ENGINE SPEED (See Fig. 6)

The engine speed is controlled by a lever located on the

side of the engine. Fast (=_) position is for starting the
engine, normal cutting, and better grass bagging. Slow

(,_) positionis for'tight cutting, trimrning and fuel economy

ENGINE ZONE CONTROL

CAUTION: Federal regulations require

an engine control to be installed on this

lawn mower in order to minimize the
risk of blade contact injury. Do not

under any circumstances attempt to
defeat the function of the operator con-

trol, The blade turns when the engine is

running,

= Your lawn mower is equipped with an operator pres-

ence control bar which requires the operator to be
positioned behind the lawn mower handle to start and

operate the lawn mower.

DRIVE CONTROL (See Fig. 7)

, Self-propelling is controlled by holding the operator

presence control bar down to the handle and pushtng
the drive control lever forward until it clicks; then

OIL (See Fig. '10)

Your lawn mower is shipped without oil in the engine.
o Be sure mower is level and area around oil fill is clean.

o Remove engine oil cap w/dipstick and fill to the full line

on the dipstick.

• Use 20 ozs. of oil, For type and grade of oil to use, see
"ENGINE" in Customer Responsibilities section of this

manual.

o Pour oil slowly. Do not over fill,.

• Check oil level before each use° Add oil if needed_ Fill

to full line on dipstick.

o To read proper level, tighten engine oil cap each time.
° Reinstall engine oil cap and tighten.

° After the first two (2) hours of mowing, change the oil,

and every 25 hours thereafter. You may need to
change the oil more often under dusty, dirty conditions.

GAS (See Fig. 10)

- FEllgasoline tank with fresh, clean, unleaded gasoline,
DO NOT USE PREMIUM GASOLINE. BE CAREFUL

NOT TO OVER FILL TANK.

WARNING: Experience 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 stor-
age of 30 days or longer° Drain the fuel tank, start the

engine and let it run untii fue! lines and carburetor are
empty. Use fresh fuel next season° See Storage instruc-

tions for additional information, Never use engine or
carburetor cleaner products in fuel tank or permanent

damage may occur°

MOWING T PS

. Under certain conditionS, such asvery tall grass, itmay

be necessary to raise the height of cut to reduce
pushing effort and to keep from overloading the engine

and leaving clumps of grass clfppings.

° For extremely heavy cutting, reduce the width of cut by

overlapping previously cut path and mow slowly.

o For better grass bagging and most cutting conditions,

the engine speed should be set in the fast (,,_) posi-
tion.

• 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 overthe area a second time.

° If a trail of clippings is left on the right side of a rear

discharge mower, mow in a clockwise direction with a
small overlap to collect the clippings on 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.

FIG. 11

MULCHING MOWING T PS

IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND

TRASH, SEE "CLEANING" IN CUSTOMER
RESPONSIBILITIES SECTION OF THIS MANUAL.

• The special mulching blade wilt recut the grass clip-
pings many times and reduce them in size so that as
they fall onto the lawn they will disperse into the grass
and not be noticed, Also, the mulched grass will
biodegrade quickly to provide nutrients for the lawn.
Always mulch with your highest engine (blade) speed

as this will provide the best recutting action of the
blades.

. Avoid cutting your lawn when it is wet. Wet grass tends

to form clumps and interferes with the mulching action.
The best time to mow your lawn is the early afternoon_

At this time the grass has dried and the newly cut area
will not be exposed to the direct sun,

o For best results, adjust the lawn mower cutting height

so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 11). If the lawn is

overgrown itwill be necessary to raise the height of cut
to reduce pushing effort and to keep from overloading
the engine and leaving clumps of mulched grass. For

extremely heavy mulching, reduce you r width of cut by
overlapping previously cut path and mow slowly.

o Certain types of grass and grass conditions may re-

quire that an area be mulched a second time to com-
pletely hide the clippings. When doing a second cut,

mow across or perpendicular to the first cut path.

• Change your cutting pattern fromweekto week. Mow
north to south one week then change to east to west the
next week. This will help prevent matting and graining

of the lawn_
