the dipstic k ( Figure 10 ).

7. If the oil lev el reading is belo w the Add mark

on the dipstic k, slo wly pour only enough oil

into the ﬁller hole to raise the oil lev el to the

Full mark on the dipstic k.

Important: Do not o v erﬁll the crankcase

with oil and r un the engine; engine dama ge

will r esult. Drain the ex cess oil until the oil

lev el on the dipstick r eads Full.

8. Inser t the dipstic k into the ﬁller nec k and

rotate the cap cloc kwise until it is tight.

Filling the Fuel Tank with

Gasoline

F or best results , use clean, fresh, lead-free g asoline

with an octane rating of 87 or higher . T o ensure

freshness , purc hase only the quantity of g asoline

that y ou expect to use in 30 da ys . Using unleaded

g asoline results in few er combustion de posits and

long er engine life . Y ou ma y use leaded g asoline if

unleaded g asoline is not a v ailable .

Important: Do not add oil to the gasoline.

Important: Do not use methanol, gasoline

containing methanol, gasohol containing

mor e than 10% ethanol, pr emium gasoline, or

white gas. Using these fuels can dama ge the

engine’ s fuel system.

Important: Do not use gasoline that has

been stor ed since the last mo wing season or

longer .

In cer tain conditions, gasoline is extr emel y

ﬂamma ble and highl y explosi v e. A ﬁr e or

explosion fr om gasoline can bur n y ou and

other s and can dama ge pr oper ty .

• Fill the fuel tank outdoor s, in an open

ar ea, and when the engine is cold. W ipe

up an y gasoline that spills.

• Do not ﬁll the fuel tank completel y full.

Add gasoline to the fuel tank until the

lev el is 1/4 to 1/2 in. (6 to 13 mm) belo w

the bottom of the ﬁller neck. T his empty

space in the tank allo ws the gasoline to

expand.

• Nev er smok e when handling gasoline,

and stay a w ay fr om an open ﬂame or

wher e a spar k may ignite the gasoline

fumes.

• Stor e gasoline in an appr o v ed fuel

container and k eep it out of the r each of

childr en.

• Nev er buy mor e than a 30-day suppl y of

gasoline.

W hen fueling , under cer tain circumstances,

a static charge can dev elop , igniting the

gasoline. A ﬁr e or explosion fr om gasoline

can bur n y ou and other s and dama ge

pr oper ty .

• Al w ays place gasoline container s on

the g r ound and a w ay fr om y our v ehicle

bef or e ﬁlling .

• Do not ﬁll gasoline container s inside

a v ehicle or on a tr uck or trailer bed

because interior car pets or plastic tr uck

bed liner s may insulate the container and

slo w the loss of an y static charge.

• W hen practical, r emo v e

gasoline-po w er ed equipment fr om

the tr uck or trailer and r efuel the

equipment with its wheels on the r ound.

• If this is not possible, then r efuel such

equipment on a tr uck or trailer fr om a

por ta ble container , not fr om a gasoline

dispenser nozzle.

• If y ou must use a gasoline dispenser

nozzle, k eep the nozzle in contact with

the rim of the fuel tank or container

opening at all times until fueling is

complete.

Use a fuel stabilizer/conditioner regularly during

operation and storag e . A stabilizer/conditioner

cleans the engine during operation and prev ents

gum-lik e v ar nish de posits from for ming in the

engine during periods of storag e .

Important: Do not use fuel additi v es other

than a fuel sta biliz er/conditioner . Do not use

fuel sta biliz er s with an alcohol base such as

ethanol, methanol, or isopr opanol.

Adjusting the Cutting

Height

Eac h wheel is adjusted indi vidually with a wheel

height adjustment lev er . Cutting heights are

1-1/4 inc hes (32 mm), 1-3/4 inc hes (44 mm),

2-1/4 inc hes (57 mm), 2-3/4 inc hes (70 mm),

3-1/4 inc hes (83 mm), and 3-3/4 inc hes (95 mm).

Adjusting the cutting height lev er s could

bring y our hands into contact with a mo ving

blade and r esult in serious injur y .

• Stop the engine and w ait f or all

mo v ement to stop bef or e adjusting the

cutting height.

• Do not put y our ﬁnger s under the

housing when adjusting the cutting

height.

Removing the Grass Bag

T o remo v e the bag, rev erse the ste ps abo v e .

T he mo w er can thr o w g rass clippings and

other objects thr ough an open discharge

tunnel. Objects thr o wn with enough f orce

could cause serious per sonal injur y or death

to the operator or bystander .

Do not operate the mo w er without a g rass

ba g installed.

Mowing with the Grass Bag

A w or n g rass ba g could allo w small stones

and other similar de bris to be thr o wn in the

operator’ s or bystander’ s dir ection and r esult

in serious per sonal injur y or death to the

operator or bystander s.

Check the g rass ba g fr equentl y . If it is

Operating Tips

General Tips

• Maintain a shar p blade throughout the cutting

season. P eriodically ﬁle do wn nic ks on the

blade .

• R e place the blade when necessar y with an

original T oro re placement blade .

• Mo w only dr y g rass or lea v es . W et g rass and

lea v es tend to clump on the yard and can cause

the mo w er to plug or the engine to stall.

W et g rass or lea v es can cause serious

injur y if y ou slip and contact the blade.

Mo w onl y in dr y conditions.

• Clean under the mo w er housing after eac h

mo wing . See Cleaning under the Mo w er

Housing .

• K ee p the engine in g ood r unning condition.

• Set the engine speed to the fastest position for

the best cutting results .

Operating a mo w er with its engine

r unning at a speed g r eater than the

f actor y setting can cause the mo w er to

thr o w a par t of the blade or engine into

the operator’ s or bystander’ s ar ea and

r esult in serious per sonal injur y or death.

– Do not change the engine speed

setting .

– If y ou suspect the engine speed

is f aster than nor mal, contact an

Authoriz ed Ser vice Dealer .

• Clean the air ﬁlter frequently . Mulc hing stirs

up more clippings and dust whic h clogs the air

ﬁlter and reduces engine perfor mance .

Cutting Grass

• Grass g ro ws at different rates at different

times of the year . In the summer heat, it is

best to cut g rass at the 2-1/4 inc h (57 mm),

2-3/4 inc h (70 mm), or 3-1/4 inc h (83 mm)

cutting height settings . Cut only about a third

of the g rass blade at a time . Do not cut belo w

the 2-1/4 inc h (57 mm) setting unless the g rass

is sparse or it is late fall when g rass g ro wth

begins to slo w do wn.

• W hen cutting g rass o v er 6 inc hes (15 cm) tall,

ﬁrst mo w at the highest cutting height setting

and w alk slo w er; then mo w ag ain at a lo w er

setting for the best la wn appearance . If the

g rass is too long and the lea v es clump on top

of the la wn, the mo w er ma y plug and cause the

engine to stall.

• Alter nate the mo wing direction. T his helps

disperse the clippings o v er the la wn for ev en

fer tilization.

If the ﬁnished la wn appearance is unsatisfactor y ,

tr y one or more of the follo wing:

• Shar pen the blade .

• W alk at a slo w er pace while mo wing .

• Raise the cutting height on y our mo w er .

• Cut the g rass more frequently .

• Ov erlap cutting sw aths instead of cutting a full

sw ath with eac h pass .

• Set the cutting height on the front wheels one

notc h lo w er than the rear wheels . F or example ,

set the front wheels at 2-1/4 inc hes (57 mm)

and the rear wheels at 2-3/4 inc hes (70 mm).

Cutting Leaves

• After cutting the la wn, ensure that half of the

la wn sho ws through the cut leaf co v er . Y ou

ma y need to mak e more than one pass o v er

the lea v es .

• F or light leaf co v erag e , set all the wheels at the

same cutting height setting .

• If there are more than 5 inc hes (12.7 cm) of

lea v es on the la wn, set the front cutting height

1 or 2 notc hes higher than the rear cutting

height. T his mak es it easier to feed the lea v es

under the mo w er housing .

• Slo w do wn y our mo wing speed if the mo w er

does not cut the lea v es ﬁnely enough.

• If y ou mo w o v er oak lea v es , y ou can add lime

to the g rass in the spring to reduce the acidity

of the oak lea v es .
