liters) of oil. Use only high-quality SAE 30 or SAE
10W30 w eight deterg ent oil that has the American
P etroleum Institute (API) ser vice classification SF ,
SG , SH, or SJ .
Oil Capacity
With oil lter
30 ounces (0.88 L)
Without oil lter
24 ounces (0.70 L)
Before eac h use , ensure that the oil lev el is betw een
the Add and Full marks on the dipstic k ( Figure 10 ).
Figure 10
1. Dipstick 3. Add
2. Full
Note: W hen the crankcase is empty , pour
about 3/4 of the crankcase capacity of oil in
the crankcase , then follo w the procedure in this
section.
1. Mo v e the la wn mo w er to a lev el surface .
2. Clean around the dipstic k ( Figure 10 ).
3. R emo v e the dipstic k b y rotating the cap
countercloc kwise and pulling it out.
4. Wipe the dipstic k clean with a clean cloth.
5. Inser t the dipstic k into the filler nec k, but do
not scr ew it in .
6. R emo v e the dipstic k and read the oil lev el on
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.

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 .
15
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 .
