BEFORE OPERATING
FILL CRANKCASE WITH OIL
Fill crankcase with SAE 30 oil until oil level reaches
FULL mark on dipstick as shown in Figure 6. 10W30
oil may be substituted if SAE 30 oil is not available.
The maximum crankcase capacity is 25 ounces (0.75
liters) of oil. Use any high quality detergent oil having
the American Petroleum Institute (API) “service classi-
fication” — SF, SG or SH.
Before each use, ensure oil level is between ADD and
FULL marks (Fig. 6). 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.
Figure 6
1. Oil fill tube 2. Dipstick 3. ADD mark 4. FULL mark
3. Wipe dipstick and insert it into filler neck. Rotate
cap 1/4 turn. Then remove dipstick and check level of
oil (Fig. 6). 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 DAM-
AGED WHEN STARTED. POUR OIL SLOWLY.
Note: Check oil level each time mower is used or af-
ter every 5 hours of mower operation. Initially, change
oil after the first 2 hours of operation; thereafter,
change oil after every 25 hours of operation. Refer to
Changing Crankcase Oil, page 13. More frequent oil
changes are required in dusty or dirty conditions.
4. Insert dipstick into filler neck and rotate cap clock-
wise 1/4 turn to lock it in place.
FILL FUEL TANK WITH GASOLINE
AN WaRnInG
DANGER: Gasoline is extremely flammable
and explosive under certain conditions. 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 gaso-
line out of reach of children.
Refuel outdoors and only when engine is cold.
Do not fill tank full. Fill tank to within 6 to 13
mm (1/4” to 1/2”) from top of tank, not into fill-
er neck. This space is for expansion of fuel.
Use funnel or spout to prevent spilling. Wipe
up any spilled gas.
Note: The Toro Company strongly recommends the
use of fresh, clean, UNLEADED regular grade gaso-
line in Toro gasoline powered products. Unleaded
gasoline burns cleaner, extends engine life, and pro-
motes good starting by reducing the build —up of
combustion chamber deposits. Leaded gasoline can
be used if unleaded is not available.
1. Clean around fuel tank cap (Fig. 8) and remove
cap from tank.
GB—7
BEFORE OPERATING
2. If there is a blue plastic cap covering the gas tank
opening, remove the cap and discard.
3. Using unleaded gasoline, fill fuel tank to within 6 to
13 mm (1/4 to 1/2 inch) from top of tank, not into the
filler neck. Do not fill tank full.
4. Install fuel tank cap and wipe up any spilled gaso-
line.
Toro also recommends that Toro Stabilizer/Condition-
er be used regularly in all Toro gasoline powered
products during operation and storage seasons. Toro
Stabilizer/Conditioner cleans the engine during oper-
ation and prevents gum-like varnish deposits from
forming in the engine during periods of storage.
IMPORTANT: Do not mix oil with the gasoline.
Never use methanol, gasoline containing metha-
nol, gasohol containing more than 10% ethanol,
premium gasoline or white gas because engine
fuel system damage could result.
Do not use fuel additives other than those man-
ufactured for fuel stabilization during storage such
as Toro's Stabilizer/Conditioner or a similar prod-
uct. Toro's Stabilizer/Conditioner is a petroleum
distillate based conditioner/stabilizer. Toro does
not recommend stabilizers with an alcohol base
such as ethanol, methanol or isopropyl. Additives
should not be used to try to enhance the power or
performance of machine.
OPERATING INSTRUCTIONS
OPERATING TIPS
1. CHECK OIL LEVEL—Maintain oil level between
ADD and FULL range as shown on dipstick (Fig. 6)-
2. BEFORE EACH MOWING—Ensure self-—propelled
drive and control bar function properly. Traction drive
and blade are designed to stop when control bar is
released.
3. CUTTING AND BAGGING— Best results are
achieved when engine is running 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 set-
ting for first mowing. Then recut the grass at a more
normal setting. If too long of grass is cut, mower may
plug and cause engine to stall.
When cutting in dry, dusty conditions move the throt-
tle to a slower speed to reduce the amount of dust
generated by mower.
4. SHARP BLADE— Begin each cutting season with a
sharp blade. Periodically file down nicks.
STARTING, STOPPING, AND SELF—-PROPELLING
CONTROLS—Throttle, ground speed control, and
self—propelled control bar are on upper handle
(Fig. 7). Fingertip starter is on top of engine (Fig. 8).
1. Push spark plug wire onto spark plug.
2. STARTING—Move ground speed control to “N”
(Fig. 7). Move throttle to [Nl (CHOKE). Brace yourself
and mower securely by placing your foot on the top
left side of mower housing. Pull recoil starter out until
positive engagement results; then pull vigorously to
start the engine. When engine starts, remove throttle
from CHOKE and regulate engine speed as desired.
3. TRACTION OPERATION (Fig. 7)—Move ground
speed control to desired setting. Number “1” is slow,
“2” is medium, and “3” is a fast walking pace.
Ground speed varies, depending on space between
control bar and handle. Move ground speed control
to “N” when using the mower for trimming and when-
ever leaving the mower.

Note: The drive wheels are equipped with freewheel-
ing clutches which enable the mower to be pulled
rearward easier when the wheel drive is disengaged.
To disengage the clutches, mower must be pushed
forward at least 2.5 cm (17) after wheel drive opera-
tion has stopped.
5. STOPPING (Fig. 9)—Release control bar to stop
blade and traction drive. Move ground speed control
to “N”. To stop engine, move throttle to & (OFF).
Pull wire off spark plug if mower will be unattended or
not used.
USING GRASS BAG
1. Stop engine and wait for all moving parts to stop.
2. INSTALLING BAG—Raise discharge door, slide
bag ramp attached to bag into discharge opening,
and hook bag frame onto mounting bracket (Fig. 10).
Allow discharge door to rest on top of bag (Fig. 11).
Note: Make sure grass bag door is fully closed
against grass bag before installing bag on mower.
3. REMOVING BAG—Stop engine and wait for all
moving parts to stop. For protection, always keep
hands and feet away from mower housing while en-
gine is running. Raise discharge door. While holding
discharge door up, grasp handle on grass bag and
lift bag off mower. Allow discharge door to close.
Note: When removing the grass bag, the bag ramp
scoops out any clippings that may be plugging the
discharge opening. If the discharge opening remains
plugged, pull wire off spark plug and clear all clip-
pings from the mower.
4. EMPTYING BAG—Grasp bag handle and rear of
grass bag. Tip bag door up and gradually tip bag
forward to empty clippings.

1. Place the bag on the mower and start the mower's
engine.
2. Push the control bar down to its lowest position
(Fig. 13, position B).
2. For easier adjustment, lift housing up so wheel is
off ground. Do not place hands under deck to lift
housing. Squeeze adjusting lever toward wheel and
move to desired setting (Fig. 12). Ensure pin on ad-
justing lever engages notch in housing. Adjust all
wheels to the same setting.
Note: Front wheels can be adjusted to 13 mm (1/27).
Move adjusting lever past “1” and release pin into
notch in housing.
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

turned to equal settings, when cutting in normal -
conditions, to achieve the best quality of cut. Figure 13
GB-10
OPERATING INSTRUCTIONS
3. Lift the control bar to the normal “blade engaged”
position (about 1” below the handle cross bar)
(Fig. 14, position C). The “fan” noise and inflation of
the bag indicate that the mower blade is turning.
Figure 14
4. Release the control bar (Fig. 14, position A). A
“bang” should be heard, the bag should deflate, and
the blade should stop within 3 seconds. If the blade
does not stop within 3 seconds when the control bar
is released in this operational mode, stop using the
mower and do not use it until you have it serviced by
an Authorized TORO Service Dealer.
If your unit stops within the required 3 seconds, the
BBC system is operating properly and needs no im-
mediate attention. However, {0 detect BBC system
deterioration before it affects normal operation, we
also ask you to perform special Control Bar Test B
which follows. |
B. Special Control Bar Test
1. The engine should be running from the previous
test. If not, start the mower’s engine.
2. Push the control bar down to its lowest position
(Fig. 15). |
3. Slowly lift the control bar to a point where the bag
just begins to inflate (about 5 inches below the han-
dle cross bar) (Fig. 16). 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 BBC sticking
which could create an unsafe condition later in the life
of the mower.
4. Release the control bar (Fig. 17).
Note: IF A BANG IS HEARD AND THE BAG IMMEDI-
ATELY DEFLATES, THE CONTROL BAR HAS BEEN
RAISED TOO HIGH. REPEAT STEPS 2, 3 AND 4,
BUT DO NOT RAISE THE HANDLE AS HIGH AS IN
STEP 3.
Figure 15
Figure 17
IF THE CONTROL BAR RETURNS TO THE LOWEST
POSITION, AND THE BAG QUICKLY DEFLATES
WHEN THE CONTROL BAR IS RELEASED, THE UNIT
IS OPERATING PROPERLY.
GB—11
OPERATING INSTRUCTIONS
If the control bar does not fall or the blade does not
quickly stop, it indicates the system could be experi-
encing wear/deterioration which could result in an
unsafe operating condition. Use care in operating the
mower and BBC system and contact an Authorized
TORO Service Dealer for an inspection of your mower
at your earliest convenience. Your dealer will ensure
that appropriate corrective measures are performed,
and your mower restored to proper operating condi-
tion.
A\ DANGER
e If Blade Brake Clutch system is inoperative,
blade will continue to rotate when control bar
is released. Contact with blade could occur.
e Blade contact can cause serious personal
injury or death.
e Never use a BBC equipped power mower
with an inoperative safety system.
e Return your lawn mower to your dealer for
repair if a safety system fails to operate
properly.
SPECIAL NOTE: Whenever performing operations
such as cleaning the mower, first stop the engine and
disconnect the spark plug wire. As with any lawn
mower, regardless of the safety features and blade
stopping devices used, operators should keep all
body parts away from the cutting blade area whenev-
er the mower’s engine is running, and keep bystand-
ers away as well.

MAINTENANCE
REPLACING SPARK PLUG
Use a CHAMPION RC12YC spark plug or equivalent.
Correct air gap is 0.76 mm (0.030). Remove plug
after every 25 operating hours and check its condi-
tion.
1. Stop engine and wait for it to cool. Pull wire off
spark plug.
2. Clean around spark plug and remove plug from
cylinder head.
IMPORTANT: Replace a cracked, fouled, or dirty
spark plug. Do not sand blast, scrape, or clean
electrodes because engine damage could result
from grit entering cylinder.
3. Set air gap at 0.76 mm (0.030”) (Fig. 19). Install
correctly gapped spark plug and gasket seal. Tighten
plug firmly to 19 N.m (14 ft—Ib).

DRAINING GASOLINE
1. Stop engine and wait for engine to cool. Pull wire
off spark plug.
Note: Drain gasoline from a cold engine only.
2. Remove cap from fuel tank and use pump—type
syphon to drain fuel into clean gas can.
Note: This is the only procedure recommended for
draining fuel.
CHANGING CRANKCASE OIL
Change oil after the first 2 operating hours and after
every 25 hours thereafter. Since warm oil drains bet-
ter and carries more contaminants than cold, run en-
gine for several minutes before draining oil.
1. Stop engine and pull wire off spark plug.
2. Lift discharge door and remove grass bag. Drain
gasoline from fuel tank: refer to Draining Gasoline,
page 13.
3. Remove dipstick from oil fill tube and place a drain
pan next to left side of mower.
4. Tip mower on its left side, allowing oil to drain into
drain pan (Fig. 20).
5. When oil is drained, return mower to upright posi-
tion and add fresh oil to engine. Refer to Fill Crank-
case With Oil, page 7.

ADJUSTING THROTTLE
Throttle control adjustment may be required if engine
does not start or stop. Whenever a new throttle con-
trol cable is installed, the throttle must be adjusted.
1. Stop engine and pull wire off spark plug.
2. Move throttle control to % (FAST) position.
3. Loosen cable clamp screw until throttle cable
slides (Fig. 21).
4. Move throttle cable left or right until holes in

3. Tip mower on its left side. Avoid rotating blade as
starting problems may result.
4. INSPECTING BLADE—Carefully examine blade for
sharpness and wear, especially where flat and curved
parts meet (Fig. 24A). Since sand and abrasive mate-
rial can wear away the metal that connects the flat
and curved parts of the blade, check blade before
using the mower. If a slot or wear is noticed, (Fig. 24B
& C), replace blade with a new TORO blade. Refer to
step 5.
Note: For optimum performance, install a new TORO
blade before cutting season begins. During the year,
file down small nicks to maintain the cutting edge.

MAINTENANCE
A DANGER
e A worn or damaged blade could break and
a piece of blade could be thrown into oper-
ator's or bystander's area.
e Athrown piece of blade could cause seri-
ous personal injury or death to operator or
bystanders.
e Inspect blade periodically for wear or dam-
age.
e Replace a worn or damaged blade.

ADJUSTING BLADE BRAKE
Blade brake adjustment may be necessary if the
quality of cut deteriorates, the bagging ability de-
grades, or the engine rpm is audibly faster than the
blade rpm when cutting grass.
1. Stop engine and pull wire off spark plug.
2. Remove (2) screws securing screen panel to top
Figure 26
IMPORTANT: Check balance of blade by putting it
on a blade balancer. An inexpensive balancer can
be purchased at a hardware store. A balanced
blade stays in a horizontal position and an unbal-
anced blade settles to the heavy side. If 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 housing to ensure correct
installation. Tighten the blade nuts to 20—37 N-m
(15-27 ft—Ib).
LUBRICATION
After every 25 operating hours or when season ends,
front and rear wheels must be lubricated.
1. Apply two or three drops of light oil on inside and
outside of all wheel bolts. Spin wheels to distribute oil
into bushings. Wipe up excess oil.
2. Move rear wheel height—of—cut levers to “2” set-
ting. Wipe grease fittings with clean rag (Fig. 27).
Install grease gun onto fitting and gently apply two or
three pumps of #2 Multi—Purpose Lithium Base
Grease.

4. If spring dimension is greater than 32 mm (11/4”)
or less than 25 mm (1”), an adjustment is needed.
5. To adjust, rotate plastic fitting on blade brake
cable (Fig. 29) until spring dimension is as near as
possible to but not less than 25 mm (1”). (See follow-
ing note.)
Note: if the spring cannot be adjusted to less than
32 mm (11/4”) before the end of the plastic fitting is
reached, the clutch belt is worn out and should be
replaced. After replacing belt, adjust cable as ex-
plained in the above procedure.
6. Reinstall screen panel.
CLEANING BLADE BRAKE CLUTCH SHIELDS
The BBC (Blade Brake Clutch) shield and the area
behind the panel screen should be cleaned periodi-
cally, at the end of each mowing season at minimum,
to ensure best performance and to prevent parts
degradation.
CLEAN BEHIND PANEL SCREEN
1. Stop engine and pull wire off spark plug.
2. Remove two 13 mm (1/2”) self—tapping SCrews
securing panel screen to mower deck and remove
panel screen (Fig. 30).

4. Remove dirt and grass clippings that stick to
housing by spraying it with a garden hose or by us-
ing a hard wood scraper. If a garden hose is used
and some debris remains, scrape out remaining de-
bris with a hardwood scraper. Avoid burrs and sharp
edges.
5. Turn mower upright.
6. Clean discharge door and hinges of grass or de-
bris that may impair operation of door.
7. Refill engine with gas.
8. If a garden hose was used to clean the housing,
start the engine and let it run for a few minutes to dry
out any moisture that may have entered it. While the
engine is running, engage and disengage the safety
system several times to dry it out.
PREPARING MOWER FOR STORAGE
1. For long term storage, it is recommended that
gasoline be drained from fuel tank or use a fuel addi-
tive before storing. To drain gasoline, refer to Draining
Gasoline, page 13. After fuel is drained, start engine
and let it idle until all fuel is consumed and engine
stops. If gasoline is not drained, gum-like varnish
deposits will form and cause poor engine operation
or even starting problems.
Fuel can be left in gas tank only if a fuel additive,
such as Toro’s Stabilizer/Conditioner, is added to
gasoline and run through engine before storing.
Toro’s Stabilizer/Conditioner is a petroleum distillate
based conditioner/stabilizer. Toro does not recom-
mend stabilizers with an alcohol base, such as etha-
nol, methanol or isopropyl. Use fuel additive in rec-
ommended quantities as specified on container.
Under normal conditions, fuel additives remain effec-
tive in fuel for 6-8 months.
2. Drain oil: refer to Changing Crankcase Oil,
page 13. After oil is drained, do not fill crankcase with
oil until the following steps (3—10) are completed.
3. Remove spark plug and pour 30 ml (2 table-
spoons) of SAE 30 oil into hole in cylinder. Pull starter
rope slowly to coat inside of cylinder. Install spark
plug and tighten to 20 N-m (15 ft-Ib). DO NOT IN-
STALL WIRE ON SPARK PLUG.
4. Clean mower housing; refer to Cleaning Mower
Housing, page 17.
5. Check condition of blade; refer to Inspecting/Re-
moving/Sharpening Blade, page 14.
6. Tighten all nuts, bolts, and screws.
7. Clean dirt, chaff, grass clippings, and grime from
external parts of the engine, shrouding, and top of
mower housing.
8. Clean air cleaner; refer to Servicing Air Cleaner,
page 12.
9. Lubricate the wheels; refer to Lubrication,
page 15.
10. Touch up all rusted or chipped paint surfaces.
Toro Re—Kote paint is available from an Authorized
TORO Service Dealer.
11. Fill crankcase with oil; refer to Fill Crankcase With
Oil, page 7.
12. Store mower in a clean, dry place. Cover mower
to keep it clean and protected.
