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.

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 ,
19
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 .
