KEY-LECTRIC® START
This mower “meets or exceeds CPSC blade safety requirements for walk be-
hind rotary mowers” and the B71.1-1986 specifications of the American Na-
tional Standards Institute. However, improper use or maintenance by the op-
erator or owner can result in injury. To reduce the potential for injury, comply
with these safety instructions and always pay attention to the safety alert sym-
bol. Failure to comply with these instructions may result in personal injury.
BEFORE OPERATING
1. Read this manual carefully before
operating the mower. Become familiar
with the controls and proper use of the
mower. Never allow children to operate
the mower or adults to operate it with-
out proper instructions.
2. Keep everyone, especially children
and pets, away from area of operation.
Thoroughly inspect area where mower
will be used and remove sticks,
stones, wire, and debris.
3. Wear long pants and substantial
shoes. Do not operate mower while
wearing open sandals or when bare-
foot.
4. Check fuel level before starting en-
gine. Do not fill fuel tank indoors, when
the engine is running, or until engine
cools for several minutes after running.
Wipe up spilled gasoline before starting
engine.
5. Keep all guards, shields, and safety
devices in place. Repair or replace de-
fective or damaged parts.
6. Traction drive and blade are de-
signed to stop when control bar is re-
leased. Assure control and brake func-
tion properly before each use of mow-
er.
WHILE OPERATING
7. Do not run engine indoors.
8. Always maintain secure footing.
Keep a firm grip on the handle and
walk, never run. Never operate mower
in wet grass. Mow only in daylight or in
good artificial light.
9. Mow across the face of slopes;
never up and down. Use extreme cau-
tion when changing direction on slopes.
Do not mow excessively steep slopes.
10. Always wear safety glasses or eye
shields during operation to protect
eyes from foreign objects that may be
thrown from the machine. Keep face,
hands, and feet away from the mower
housing and cutter blade when the en-
gine is running. Stay behind the handle
until the engine stops and keep clear
of discharge opening at all times.
11. When mulching, assure discharge
door is closed. When bagging grass,
stop engine before the bag is removed
and emptied.
12. Shut engine off and wait for all
moving parts to stop before unciogging
chute.
13. Since the blade rotates for a few
seconds after the blade control is re-
leased, stay behind the handle until all
moving parts stop.

A) SAFETY INSTRUCTIONS
14. After striking a foreign object or if
mower vibrates abnormally, stop en-
gine and remove wire from spark plug.
Check mower for damage and make all
repairs before using mower again.
15. Stop the engine before adjusting
the height-of-cut.
16. Stop the blade when crossing a
gravel driveway, road, or sidewalk.
17. Stop engine before leaving the op-
erator’s position—behind the handle.
Disconnect wire from spark plug if
mower will be unattended.
18. Do not touch engine while it is run-
ning or shortly after it is stopped be-
cause engine will be hot enough to
cause a burn.
MAINTENANCE
19. Perform only those maintenance
instructions described in this manual. If
major repairs are ever needed or if as-
sistance is desired, contact your local
Authorized TORO Service Dealer.
20. Before mower is cleaned, in-
spected, serviced, or adjusted, stop
engine and disconnect high tension
wire from spark plug. Keep wire away
from plug to prevent accidental start-
ing.
21. To assure the mower is in safe op-
erating condition, frequently check and
keep all nuts, bolts, and screws tight.
Assure blade nuts are tightened to
25-33 ft-lb.
22. To reduce fire hazard, keep engine
free of excessive grease, grass,
leaves, and accumulations of dirt.
23. Check grass catcher bag frequently
for wear or deterioration. Replace with
a new bag for your protection.
24, Allow engine to cool before storing
mower in any enclosure. Do not store
mower near any open flame or where
gasoline fumes may be ignited by a
spark.
25. Do not overspeed the engine by
changing governor settings.
26. At the time of manufacture, the
mower conformed to the safety stan-
dards in effect for rotary mowers. To
assure optimum performance and con-
tinued safety certification of the mow-
er, use genuine TORO replacement
parts and accessories. Replacement
parts and accessories made by other
manufacturers may result in non-con-
formance with the safety standards,
and that could be dangerous.

BEFORE OPERATING
FILL CRANKCASE WITH OIL
Initially, crankcase must be filled with
18 ounces (0.532 I) of SAE 10W30 oil.
Use any high quality detergent oil hav-
ing the American Petroleum Institute
(API) “service classification” —MS, SC,
SD, SE, or SF.
Before each use, assure oil level is be-
tween ADD and FULL marks on dipstick
(Fig. 5). Add oil if level is low.
1. Position mower on level surface and
clean around oil dipstick.
2. Remove dipstick by rotating cap
counterclockwise 1/4 turn.
3. Wipe dipstick and insert it into filler
neck. Rotate cap clockwise 1/4 turn.
Then remove dipstick and check level
of oil (Fig. 5). If level is low, add only
enough oil to raise level to FULL mark
on dipstick. DO NOT FILL ABOVE
FULL MARK BECAUSE ENGINE COULD
BE DAMAGED WHEN STARTED. POUR
SLOWLY.
4. Insert dipstick into filler neck and
rotate cap clockwise 1/4 turn to lock.

change oil after every 25 hours of op-
eration. More frequent oil changes are
required in dusty or dirty conditions.
spilling. Wipe up any spilled gas.
DANGER: Gasoline is extremely flammable and explosive under certain condi-
tions. Do not smoke when handling fuel and keep fuel far away from open
flames and sparks. Never buy more than a 30 day supply of gasoline. Store
it in an approved container. Keep gasoline out of reach of children.
Refuel outdoors and only when engine is cold. Do not fill the tank full. Fill
tank to 1/4” (6 mm) below the bottom of the filler neck, not into the filler
neck. This space is for expansion of fuel. Use funnel or spout to prevent
FILL FUEL TANK WITH GASOLINE
Note: The Toro Company strongly rec-
ommends the use of fresh, clean, UN-
LEADED regular grade gasoline in Toro
gasoline powered products. Unleaded
gasoline burns cleaner, extends engine
lite, and promotes good starting by re-
ducing the build-up of combustion
chamber deposits. Leaded gasoline
can be used if unieaded is not avail-
able.
1. Clean around fuel tank cap and re-
move cap from tank (Fig. 5). Using
unleaded gasoline, add fuel to 1/4”
(6 mm) from bottom of filler neck. Do
not fill the tank full.
2. Install fuel tank cap and wipe up any
spilled gasoline.
BEFORE OPERATING
IMPORTANT: Do not mix oil with the
gasoline. Never use methanol, gaso-
line containing methanol, gasohol
containing more than 10% ethanol,
premium gasoline, or white gas be-
cause engine fuel system damage
could result.
Do not use fuel additives other than
those manufactured for fuel stabiliza-
tion during storage (such as Toro's
Preservit or a similar product). Addi-
tives should not be used to try to en-
hance the power or performance of
machine.
OPERATING INSTRUCTIONS
OPERATING TIPS
1. CHECK OIL LEVEL —Maintain oil level
between ADD and FULL marks as
shown on dipstick (Fig. 5).
2. BEFORE EACH MOWING-—Assure
blade brake, self-propelled drive, and
control bar function properly. When
control bar is released blade and self-
propelied drive are designed to stop.
3. CUTTING AND BAGGING—Best re-
sults are achieved when engine is run-
ning at maximum speed and only about
1/3 of the grass blade is cut. If long
grass must be cut, use highest height-
of—cut setting for first mowing. Then
recut the grass at a more normal set-
ting. If too long of grass is cut, mower
may plug and cause engine to stall.
When cutting in dry, dusty conditions
move the throttle to a slower speed to
reduce the amount of dust generated
by mower.
4. MULCHING~In summer when grass
grows slower and is drier, mulch by
removing the grass bag and closing
the discharge door (Fig. 6).
5. SHARP BLADE—Begin each cutting
season with a sharp blade. Periodically
file down nicks.

3. CHECKING BAG—To see if grass bag
is full, release control bar and wait for
blade to stop. Feel the bag to deter-
mine whether bag needs to be emp-
tied.
Never open discharge door on
mower when grass bag is not in-
stalled and engine is running be-
cause grass clippings and other
debris discharge with enough
force to cause injury.
The grass bag material will catch
and contain the majority of for-
eign objects such as small stones
and other similar debris. The bag
material, however, is subject to
normal wear and deterioration. So
check the bag frequently, and if
it is worn, install a new genuine
TORO replacement bag that has
this or similar warning.
4. REMOVING BAG—Stop engine and
wait for all moving parts to stop. For
protection, always keep hands and feet
away from mower housing when engine
is running. Open discharge door. While
holding discharge door, grasp handle
on grass bag and lift bag off mower.
Allow discharge door to close.
5. EMPTYING BAG—Grasp bag frame
handle and rear of bag. Gradually raise
rear of bag while shaking bag to
empty.
Note: If grass bag is overfilled, some
clippings may remain in discharge
opening when bag is removed. Nor-
mally, these clippings will be blown into
grass bag when the bag is reinstalled
and the blade is engaged.
DANGER: If the discharge opening re-
mains plugged, be sure to stop en-
gine and wait for all moving parts to
stop before attempting to clear any
clippings from the mower.
ADJUSTING HEIGHT-OF-CUT

represent 1/2” increments.
settings when engine is running.
1. Stop the engine.
2. For easier adjustment, lift housing
up so wheel! is off ground. Squeeze
adjusting lever toward wheel and move
to desired setting. (Fig. 12). Assure pin
on adjusting lever engages notch in
housing. Adjust all wheels to the same
setting.
Note: Front wheels can be adjusted to
1/2”. Move adjusting lever past “1”
and release pin into notch in housing.
OPERATING INSTRUCTIONS
3. In conditions when maximum power
is required or when cutting in spongy
thatch that causes rear wheels to sink
in turf, raise rear wheel setting one in-
crement higher. Make sure wheel set-
tings are returned to equal settings,
when cutting in normal conditions, to
achieve the best quality of cut.

CHECK CONTROL BAR OPERATION
Control bar should be checked periodi-
cally, at the beginning of each mowing
season as a minimum, to assure the
Blade Brake Clutch (BBC) system is
operating properly.
1. Start engine; refer to Starting,
page 6.
2. Push the control bar down to the
lowest position (Fig. 13). This
“latches” the mechanism prior to en-
gaging the blade.
3. Lift the control bar to the normal
“blade engaged” position, about 2”
below the handle. The “fan” noise and
bag inflation indicate that the mower
blade is engaged and rotating.
4. Release the control bar. A “bang”
should be heard, and the blade should
stop within 3 seconds. If the blade
does not stop within 3 seconds when
the control bar is released, stop using
it until it has been serviced by an
Authorized TORO Service Dealer.
if your unit stops within the required 3
seconds, the BBC system is operating
properly. However, to detect BBC sys-
tem deterioration before it affects nor-
mal operation, proceed to step 5.
5. if necessary, start engine.
6. Push the control bar down to its
lowest position, latching the mecha-
nism (Fig. 13).
CONTROL
BAR
Figure 13
7. Slowly lift the control bar to a point
where the bag just begins to intlate
(about 5” below the handle) (Fig. 13).
This indicates that the mower blade is
engaged and has begun to rotate.
Note: This intermediate position is not
the “natural” operating position of the
control bar. However, it has proven to
be useful in early detection of latent
BBC sticking which could create an un-
safe condition later in the life of the
mower.
8. Release the control bar.
Note: If a “bang” is heard and the bag
immediately deflates, the control bar
had been raised too far. Repeat steps
6, 7 & 8, but do not raise the handle
as high as in step 8.
If the control bar “hangs up” and the
blade does not stop quickly, it indi-
cates possible deterioration has set in,
which could result in an unsafe operat-
ing condition. Have mower inspected
by an Authorized TORO Service Dealer.

OPERATING INSTRUCTIONS
» CAUTION: If the control bar “hangs
up”, and the blade does not stop
quickly, you should stop the blade be-
fore shutting off the engine. This can
be done by raising the control bar to
the normal operating position and re-
leasing it.
MAINTENANCE
performing adjustments or
maintenance.
SERVICING AIR CLEANER
Normally, clean air cleaner after every
25 operating hours. More frequent
cleaning is required when mower is op-
erated in dusty or dirty conditions.
1. Stop engine. Pull wire off spark plug
and remove key from switch.
2. Push in locking tabs and lift off air
cleaner cover. Clean cover thoroughly
(Fig. 14).

3. If top of foam element is dirty, re-
move it from air cleaner body
(Fig. 14). Clean thoroughly.
A. WASH foam element in a solution of
liquid soap and warm water.
Squeeze to remove dirt, but do not
twist because foam may tear. Rinse
thoroughly in clear water.
B. DRY by wrapping in a clean rag.
Squeeze rag and foam element to
dry.
10
C. SATURATE element with 5 tea-
spoons (25 ml) of SAE 10W30 en-
gine oil. Squeeze element to re-
move excess oil and to distribute oil
thoroughly. A damp element is de-
sirable.
4. Reinstall foam element and air
cleaner cover.
IMPORTANT: Do not operate engine
without air cleaner element because
extreme engine wear and damage will
likely result.
REPLACING SPARK PLUG
Use an NGK BPRGES spark plug or
equivalent. Correct air gap is 0.032”
(0.813 mm). Remove plug after every
25 operating hours and check its con-
dition.
1. Stop engine and pull wire off spark
plug.
2. Clean around spark plug and re-
move plug from cylinder head.
IMPORTANT: Replace a cracked,
fouled, or dirty spark plug. Do not
sand blast, scrape, or clean elec-
trodes because engine damage could
result from grit entering cylinder.
3. Set air gap at 0.032” (0.813 mm)
(Fig. 15). Install correctly gapped
spark plug and gasket seal. Tighten
plug firmly to 15 ft-lb (20.4 N-m).

clean gas can.
Note: This is the only procedure rec-
ommended for draining fuel.
CHANGING CRANKCASE OIL
Change oil after the first 2 operating
hours and after every 25 hours thereaf-
ter. Since warm oil drains better and
carries more contaminants than cold,
run engine for a minute or so before
draining oil.
1. Stop engine. Pull wire off spark plug
and remove key from switch.
2. Remove grass bag. Drain gasoline
from fuel tank: refer to Draining Gaso-
line, page 11.

nicks to maintain the cutting edge.
6. SHARPENING BLADE—Using a file,
sharpen top side of blade (side facing
mower housing) and maintain original
cutting angle (Fig. 23). The blade will
remain balanced if the same amount of
material is removed from both cutting
edges.

IMPORTANT: Check balance of blade
by putting it on a blade balancer. An
inexpensive balancer can be pur-
chased at a hardware store. A bal-
anced blade will stay in a horizontal
position and an unbalanced blade will
settle to the heavy side. If the blade
is not balanced, file more metal off
cutting edge on heavy end of blade.
7. Install rotating screen (outside
flange pointing away from housing),
blade spacer, sharp, balanced blade,
and anti-scalp cup with blade nuts. Sail
part of blade must point toward top of
mower housing to assure correct in-
stallation. Tighten the blade nuts to
25-33 ft-lb.
LUBRICATION
After every 25 operating hours or when
season ends, front and rear wheels
must be lubricated.
1. Apply 2 or 3 drops of light oil on
inside and outside of all wheel bolts.
Spin wheels to distribute oil into bush-
ings. Wipe up excess oil.
2. Move rear wheel height-of-cut lev-
ers to “2” setting. Wipe grease fittings
with clean rag (Fig. 24). Install grease

4. If spring dimension is greater than
1-1/4" or less than 1”, an adjustment
is needed.
5. To adjust, loosen bottom jam nut on
blade brake cable (Fig. 27) and adjust
top jam nut until spring dimension is as
near as possible to but not less than
1”. (See note below.)
NOTE: Adjusting the top jam nut too
high can cause the cable end to crush
the platic fitting whne the control bar is
moved up against the handle. If the
spring cannot be adjusted to less than
1-1/4" before the cable end contacts

the plastic fitting, the clutch belt is
worn out and should be replaced. After
replacing belt, adjust cable as ex-
plained in the above procedure.

6. Tighten bottom jam nut to lock the
adjustment in place.
CHARGING BATTERY
Although a new battery is not fully
charged, a partial charge of 4 hours
provides enough energy for several
starts. However, a new battery must
be charged for 72 continuous hours to
assure full charge. Also charge battery
for 72 hours when mower is stored and
in the spring. During normal operation,
engine alternator keeps battery
charged.
1. Stop engine and disconnect wire
harness from battery terminal
(Fig. 28).
2. if desired, battery can be removed
by sliding it out of mounting tabs. How-
ever, removal is not required if mower

PREPARING MOWER FOR STORAGE
1. For long term storage, it is recom-
mended that gasoline be drained from
fuel tank; refer to Draining Gasoline,
page 11. After fuel is drained, start en-
gine and let it idle until all fuel is con-
sumed and engine stops. If gasoline is
not drained, gum-like varnish deposits
will form and cause poor engine opera-
tion, even starting problems.
Fuel can be left in gas tank only if a
fuel additive such as Toro’s Preservit is
added to gasoline before storing. Use
fuel additive in recommended quanti-
ties as specified on container.
2. Drain oil: refer to Changing Crank-
case Qil, page 11. After oil is drained,
do not fill crankcase with oil until the
following steps (3-11) are completed.
