BEF RE PERATING
FILL FUEL TANK WITH GAS LINE
DANGER: Gasoline is extremely flammable
and explosive under certain conditions. D
N T SM KE 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 gasoĆ
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 fillĆ
er neck. This space is for expansion of fuel.
Use funnel or spout to prevent spilling. Wipe
up any spilled gas.

IMP RTANT: Do not mix oil with the gasoline.
Never use methanol, gasoline containing
methanol, 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
manufactured for fuel stabilization during storage
such as Toro's Stabilizer/Conditioner or a similar
product. 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.

CHECK IL LEVELĊMaintain oil level between
ADD and FULL range as shown on dipstick (Fig. 7).
BEF RE EACH M WINGĊEnsure self-propelled
drive and control bar function properly. Traction drive
and blade are designed to stop when control bar is
released.
CUTTING AND BAGGINGĊBest 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
setting 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
throttle to a slower speed to reduce the amount of
dust generated by mower.
SHARP BLADEĊBegin each cutting season with a
sharp blade. Periodically file down nicks.
C NTR LSĊThrottle, ground speed control, and
self-propelled control bar and fingertip starter are on
upper handle (Fig. 9).

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

POTENTIAL HAZARD
•If the Blade Brake Clutch system is
inoperative, blade will continue to rotate
when control bar is released. Contact with
blade could occur.
WHAT CAN HAPPEN
•Blade contact can cause serious personal
injury or death.
HOW TO AVOID THE HAZARD
•Never use a BBC equipped power mower
with an inoperative safety system.
•Return your lawn mower to your dealer for
repair if a safety system fails to operate
properly.
Whenever performing operations
such as cleaning the mower, first stop the engine and
disconnect the spark plug wire. Remove key from
switch on electric start model. As with any
lawnmower, regardless of the safety features and
blade stopping devices used, operators should keep
all body parts away from the cutting blade area
whenever the mower's engine is running, and keep
bystanders away as well.
Should you require further information or assistance,
feel free to contact us at:

he grass bag can be used for an additional test to
check the Blade Brake Clutch mechanism.
Install the empty grass bag on the discharge
tunnel.
Start the engine.
Push the control bar (Fig. 18) down to the lowest
position.
Lift the control bar to the normal blade engaged
position, about one inch below the handle. he bag
should begin to inflate which indicates the blade is
engaged and rotating.
Release control bar. If the bag does not
immediately deflate, it indicates the blade is still
rotating. Deterioration of the Blade Brake Clutch
mechanism may have set in, which could result in an
unsafe operating condition. Have mower inspected
by an Authorized ORO Service Dealer.

3. Lift cover off. Clean cover thoroughly.
4. Carefully remove preĆcleaner. If preĆcleaner is dirty,
carefully wash it in a solution of liquid soap and warm
water. Rinse in clear water. Allow to dry thoroughly
before using.
5. If paper cartridge is dirty, clean the paper filter by
tapping it gently on a flat surface. If very dirty,
replace cartridge.
IMPO TANT: Do not oil pre-cleaner or paper
cartridge. Do not use pressurized air to clean
paper cartridge.
6. Reinstall preĆcleaner over paper cartridge.
Reinstall air cleaner cover and tighten securely in
place with two (2) knobs.
IMPO TANT: Do not operate engine without air
cleaner element otherwise extreme engine wear
and damage will likely result.
EPLACING SPA K PLUG
Use a CHAMPION RC12YC spark plug or equivalent.
Correct air gap is 0.5 mm (0.020"). Remove plug after
every 25 operating hours and check its condition.
1. Stop engine and wait for it to cool. Pull wire off
spark plug (Fig. 10).
2. Clean around spark plug and remove plug from
cylinder head.
IMPO TANT: eplace 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 0.5 mm (0.020") (Fig. 21). Install
correctly gapped spark plug and gasket seal. Tighten
plug firmly to 19 Nm (14 ft-lb).

D AINING GASOLINE
1. Stop engine and wait for engine to cool. Pull wire
off spark plug (Fig. 10).
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 C ANKCASE OIL
Change oil after the first 5 operating hours and after
every 50 hours thereafter. Since warm oil drains
better and carries more contaminants than cold, run
engine for several minutes before draining oil.
1. Drain gasoline. Refer to Draining Gasoline section.
2. Run engine until it dies. Try starting engine once
more to make sure gas is out of carburetor.
3. Pull wire off spark plug (Fig. 10).
4. Lift discharge door and remove grass bag. Drain
gasoline from fuel tank: refer to Draining Gasoline,
page 15.
5. Remove dipstick from oil fill tube and place a drain
pan next to left side of mower.
6. Tip mower on its left side, allowing oil to drain into
drain pan (Fig. 22).
7. hen oil is drained, return mower to upright
position and add fresh oil to engine. Refer to Fill

IN PECTING BLADEĊCarefully examine blade for
sharpness and wear, especially where flat and curved
parts meet (Fig. 26A). ince sand and abrasive
material 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. 26B
& C), replace blade with a new TORO blade. Refer to
step 5.

Whenever the underside of the mower requires
cleaning, follow this procedure for washing debris out
from underside of deck.
Position mower on a flat concrete or asphalt
surface near a garden hose.
Start the engine.
Engage the blade.
Hold the running garden hose at handle level and
direct water to flow on ground just in front of right
rear tire (Fig. 36). The rotating blade will draw water
under the housing and wash out clippings. Let the
water run for a few minutes or until you no longer see
clippings being washed out from under housing.
Disengage the blade.
Stop the engine.
Turn off the garden hose.
Restart mower and let it run for a few minutes to
dry out moisture on the mower and its components.
While the engine is running, engage and disengage
the blade and traction drive several times to dry them

Use a hard wood scraper to remove dirt and grass
clippings that stick to housing. Avoid burrs and sharp
edges.
Turn mower upright.
Clean discharge door and hinges of grass or
debris that may impair operation of door.
Refill engine with gas.
Reinstall spark plug wire.
For long term storage, it is recommended that
gasoline be drained from fuel tank or use a fuel
additive before storing. To drain gasoline, refer to
Draining Gasoline, page 15. 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
recommend stabilizers with an alcohol base, such as
ethanol, methanol or isopropyl. Use fuel additive in
recommended quantities as specified on container.
Under normal conditions, fuel additives remain
effective in fuel for 6Ć8 months.
Drain oil: refer to Changing Crankcase il,
page 15. After oil is drained, do not fill crankcase with
oil until the following steps (3-10) are completed.
Remove spark plug and pour 30 ml
(2 tablespoons) of SAE 30 oil into hole in cylinder.
Pull starter rope slowly to coat inside of cylinder.
Install spark plug and tighten to 20 Nm (15 ft-lb).
