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.

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

dama ged, install a new T or o r eplacement

ba g .

Removing the Grass Bag

1. Stop the engine and w ait for all mo ving par ts

to stop .

2. Raise the disc harg e door handle and mo v e

it forw ard to eng ag e the pin with the catc h

( Figure 19 ).

the bag and lift the bag off the la wn mo w er .

4. Gradually tip the bag forw ard to empty the

clippings .

5. T o install the bag, refer to Installing the Grass

Bag .

If the discharge door does not close

completel y , the la wn mo w er could thr o w

objects, causing serious per sonal injur y or

death.

If y ou cannot close the door because the

g rass clippings clo g the discharge ar ea, stop

the engine and gentl y mo v e the discharge

door handle back and f or th until y ou can

close the door completel y . If y ou still cannot

close the door , r emo v e the obstr uction with

a stick, not y our hand.

T he la wn 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 .

Nev er open the door on the discharge tunnel

when the engine is r unning .

Operating Tips

General Tips

• R eview the safety instr uctions and read this

man ual carefully before operating the la wn

mo w er .

• Clear the area of stic ks , stones , wire , branc hes ,

and other debris that the blade could hit and

thro w .

• K ee p ev er y one , especially c hildren and pets ,

a w a y from the area of operation.

• A v oid striking trees , w alls , curbs , or other solid

objects . Nev er deliberately mo w o v er any

object.

• If the la wn mo w er strik es an object or star ts

to vibrate , immediately stop the engine ,

disconnect the wire from the spark plug, and

examine the la wn mo w er for damag e .

• 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 la wn 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 the underside of the la wn mo w er dec k

after eac h mo wing . See Cleaning the Underside

of the La wn 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 la wn mo w er with its engine

r unning at a speed g r eater than the

f actor y setting can cause the la wn 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 inc h (51 mm), 2-1/2 inc h (64

mm), or 3 inc h (76 mm) cutting height settings .

Cut only about a third of the g rass blade at a

time . Do not cut belo w the 2 inc h (51 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 la wn 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 la wn 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 inc hes (51 mm) and

the rear wheels at 2-1/2 inc hes (64 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 la wn mo w er dec k.

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

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 .
