SAFETY INSTRUCTIONS
The safety alert symbol means |
CAUTION, WARNING or DAN-
GER — “personal safety in-
struction”. Read and under
stand the instruction because
it has to do with safety. Failure to comply with
! the instruction may result in personal injury.
CUO DD
Hazard control and accident prevention are depen-
dent upon the awareness, concern, and proper
training of the personnel involved in the operation,
transport, maintenance, and storage of the ma-
chine. Improper use or maintenance of the machine
can result in injury or death. To reduce the potential
for injury or death, comply with the following safety
instructions.
WARNING: Engine exhaust contains carbon monox-
ide which is an odorless, deadly poison. Carbon mon-
oxide is also known to the State of California to cause
birth defects. Do not run engine indoors or in an en-
closed area.
BEFORE OPERATING
1. Read and understand the contents of this Opera-
tor's Manual before operating the machine. Become
2
familiar with all controls and know how to stop quickly.
A free replacement manual is available by sending
complete Model and Serial Number to:
The Toro Company
8111 Lyndale Avenue South
Bloomington, Minnesota 55420-1196
2. Never allow children to operate the machine. Do
not allow adults to operate machine without proper in-
struction. Only trained operators who have read this
manual should operate this machine.
3. Never operate the machine when under the influ-
ence of drugs or alcohol.
4. Before attempting to start engine, shift into neutral
and lock parking brake.
5. Remove all debris or other objects that might be
picked up and thrown by the cutter blades. Keep all by-
standers away from the mowing area.
6. Do not operate unless all shields and safety de-
vices are in place. If a shield, safety device or decal is
illegible or damaged, repair or replace it before opera-
tion is commenced. Also tighten any loose nuts, bolts
and screws to assure machine is in safe operating con-
dition.
SAFETY INSTRUCTIONS
7. Do not operate machine while wearing sandals,
tennis shoes, sneakers or shorts. Also, do not wear
loose fitting clothing which could get caught in moving
parts. Always wear long pants and substantial shoes.
Wearing safety glasses, safety shoes and a helmet is
advisable and required by some local ordinances and
insurance regulations.
8. Fill fuel tank with gasoline before starting the en-
gine. Avoid spilling gasoline. Since gasoline is flam-
mable, handle it carefully.
A. Use an approved gasoline container.
B. Do not fill tank while engine is hot or running.
C. Do not smoke while handling gasoline.
D. Fill fuel tank outdoors and up to about one inch
(25 mm) from top of the tank, not the filler neck.
E. Wipe up any spilled gasoline.
WHILE OPERATING
9. Start engine when parking brake is set, blade is
disengaged, and transmission is in neutral.
10. Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous
and could possibly be deadly.
11. Using the machine demands attention, and to pre-
vent loss of control:
A. Mow only in daylight or when there is good artifi-
cial light.
B. Watch for holes or other hidden hazards.
C. Do not drive close to a sand trap, ditch, creek or
other hazard.
D. Reduce speed when making sharp turns and
when turning on hillsides.
12. The grass deflector must always be installed and in
lowest position on the side discharge cutting unit, ex-
cept when using the optional grass catcher. This prod-
uct is designed to drive objects into the ground where
they lose energy quickly in grassy areas. However
don’t take an injury risk!! When a person or pet ap-
pears unexpectedly in or near the mowing area, STOP
MOWING. Careless operation, combined with terrain
angles, ricochets, or improperly positioned guards,
can lead to thrown object injuries. Do not resume mow-
ing until area is cleared. If the cutting unit discharge
area ever plugs, shut engine off before removing the
obstruction.
13. Never raise the cutting unit while the blades are ro-
tating.
14. Ifthe cutting blades strike a solid object or the ma-
chine vibrates abnormally, shut the engine off. Remove
spark plug wire from spark plug to prevent possibility of
accidental starting. Check cutting unit and traction unit
for damage and malfunctioning parts. Repair any dam-
age before restarting the engine and operating the cut-
ting unit. Be sure blades are in good condition and
blade bolts are tight.
15. Cut grass slopes carefully. Do not start, stop, or
turn suddenly.
16. Do not touch engine or muffier while engine is run-
ning or soon after it is stopped. These areas could be
hot enough to cause a burn.
17. Before leaving the operator's position — behind
handle or leaving mower unattended, shift transmis-
sion into NEUTRAL, apply parking brake, release con-
trol bail and shut OFF engine.
MAINTENANCE
18. Disconnect spark plug wire from spark plug to pre-
vent accidental starting of the engine when servicing,
adjusting or storing the machine.
19. If traction unit and mower must be tipped to per-
form maintenance or an adjustment, drain gasoline
from fuel tank and oil from crankcase.
20. When driving unit forward, always use upper “For-
ward” traction drive handle. When backing up, always
use lower “Reverse” traction drive handle.
21. To reduce potential fire hazard, keep the engine
free of excessive grease, grass, leaves and accumula-
tions of dirt.
22. Be sure machine is in safe operating condition by
keeping nuts, bolts and screws tight. Check the blade
mounting bolts and nuts frequently to be sure they are
tightened to specification.
23. Ifthe engine must be running to perform a mainte-
nance adjustment, keep hands, feet, clothing and oth-
er parts of the body away from the cutting unit blades
and other moving parts.
24. Do not overspeed the engine by changing gover-
nor settings. To be sure of safety and accuracy, have an
Authorized TORO Proline Service Dealer check maxi-
mum engine speed with a tachometer.
25. Engine must be shut off before checking oil or add-
ing oil to the crankcase.
26. Allow engine to cool before storing mower in any
enclosure such as a garage or storage shed. Make
sure the mower fuel tank is empty if machine is to be
stored in excess of 30 days. Do not store mower near
any open flame or where gasoline fumes may be ig-
nited by a spark. Always store gasoline in a safety —ap-
proved, red metal container.
27. Perform only those maintenance instructions de-
scribed in this manual. If major repairs are ever needed
or assistance is desired, contact an Authorized Toro
Proline Service Dealer. To ensure optimum perform-
ance and safety, always purchase genuine TORO re-
placement parts and accessories to keep the Toro all
TORO. NEVER USE “WILL—FIT” REPLACEMENT
PARTS AND ACCESSORIES MADE BY OTHER MAN-
UFACTURERS. Look for the TORO logo to assure gen-
uineness. Using unapproved replacement parts and
accessories could void the warranty of The Toro Com-
pany.

BEFORE OPERATING
FILL CRANKCASE WITH OIL
The engine does not have oil in the crankcase when
itis shipped from the factory. If engine is started be-
fore oil is added to the crankcase, engine damage
could result. Therefore, before engine is started for
the first time:
1. Position mower on level surface.
2. Clean area around the oil dipstick to prevent for-
eign matter from entering the filler hole when dipstick is
removed.
3. Remove dipstick (Fig. 10).
Figure 10
1. Dipstick
4. Slowly pour approximately 4 pints of oil into the fill-
er neck. The engine uses any high quality detergent oil
having the American Petroleum Institute —API — “ser-
vice classification” SF. The recommended oil to use is:
SAE 5W20 or 5W30 (below 320 F) SAE 30 (above 320
F). SAE 10W30 or 10W40 may also be used when tem-
perature is above OOF.
5. Wipe end of dipstick with cleanrag and insert it into
filler neck. Then remove the dipstick and check level of
oil by reading the dipstick (Fig. 10). If level of oil is low,
add only enough oil to raise level to FULL mark on dip-
stick. DO NOT ADD OIL SO LEVEL RISES ABOVE FULL
MARK BECAUSE ENGINE COULD BE DAMAGED
WHEN IT IS STARTED.
6. Insert dipstick into filler neck and tighten.
Note: Check level of oil after every 5 operating hours or
each time the mower is used. Initially, change oil after
the first 5 hours of operation; thereafter, when condi-
tions are normal, change oil after every 50 hours of op-
eration. However, change oil more frequently when
mower is operated in dusty or dirty conditions.
CHECK TIRE PRESSURE
Tires are over inflated at the factory. Check tires and in-
sure they are inflated to 15 psi.
FILL FUEL TANK WITH GASOLINE
THE TORO COMPANY STRONGLY RECOMMENDS
THE USE OF FRESH CLEAN, UNLEADED REGULAR
GRADE GASOLINE IN TORO GASOLINE POWERED
PRODUCTS. UNLEADED GASOLINE BURNS CLEAN-
ER, EXTENDS ENGINE LIFE, AND PROMOTES GOOD
STARTING BY REDUCING THE BUILD-UP OF COM-
BUSTION CHAMBER DEPOSITS.
NOTE: NEVER USE METHANOL, GASOLINE CON-
TAINING METHANOL, GASOHOL CONTAINING
MORE THAN 10% ETHANOL, GASOLINE ADDI-
TIVES, PREMIUM GASOLINE, OR WHITE GAS BE-
CAUSE ENGINE FUEL SYSTEM DAMAGE COULD
RESULT.
1. Clean area around fuel tank cap and remove cap
from tank.
2. Fill fuel tank to about 1 inch from top of the tank,
not filler neck. Install fuel tank cap securely.
3. Wipe up spilled gasoline.
A DANGER
Because gasoline is flammable, caution
must be used when storing or handlingit.
Do not fill fuel tank while engine is
running, hot or when machine is in an
enclosed area. Vapors may build up and
be ignited by a spark or flame source
many feet away. DO NOT SMOKE while
filling the fuel tank to prevent the possi-
bility of an explosion. Always fill fuel tank
outside and wipe up any spilled gasoline
before starting engine. Use a funnel or
spout to prevent spilling gasoline before
starting engine and fill tank to about one
inch from top of tank, not filler neck.
Store gasoline in a clean safety— ap-
proved container and keep the cap in
place on the container. Keep gasoline In
a cool, well —ventilated place; never in an
enclosed area such as a hot storage
shed. To assure volatility, do not buy
more than a 30 day supply of gasoline.
Gasoline is a fuel for internal combus-
tion engines; therefore, do not use it for
any other purpose. Since many children
like the smell of gas, keep it out of their
reach because the fumes are explosive
and dangerous to inhale.

clamps
1. Close fuel shut off valve, loosen the hose clamp on
the carburetor side of filter and remove the fuel line
from the filter.
2. Place a drain pan under filter, loosen the remaining
hose clamp and remove filter.
CAUTION
Since gasoline is highly flammable, drain it
outdoors and make sure engine is cool to
prevent a potential fire hazard. Wipe up any
gasoline that may have spilled. Do not drain
gasoline near any open flame or where gas-
oline fumes may be ignited by a spark. Do
not smoke a cigar, cigarette, or a pipe when
handling gasoline.
3. Install the new filter with arrow on the filter body
pointing towards the carburetor.
REPLACING SPARK PLUG
Since air gap between center and side electrodes of
the spark plug increases gradually during normal oper-
ation of the engine, check condition of electrodes after
every 50 operating hours. Recommended air gap is
0.035 ofan inch (0.9 mm). Correct spark plug to use is a
Champion RC 12YC.
11
MAINTENANCE
Note: The spark plug usually lasts a long time; howev-
er, the plug should be removed and checked whenever
the engine malfunctions.
1. Clean area around spark plug so foreign matter
cannot fall into cylinder when spark plug is removed.
2. Pull spark plug wire off spark plug and remove plug
from cylinder head.
3. Check condition of side electrode, center elec-
trode, and center electrode insulator to assure there is
no damage.
IMPORTANT: A cracked, fouled, dirty or otherwise
malfunctioning spark plug must be replaced. Do
not sand blast, scrape, or clean electrodes by using
a wire brush because grit may eventually release
from the plug and fall into the cylinder. The resultis
usually a damaged engine.
4. Set air gap between center and side of electrodes
at 0.035 of an inch (0.9 mm) (Fig. 18). Install correctly
gapped spark plug w/gasket seal, and tighten plug to
18 ft—Ib (24.4 Nm). Iftorque wrenchis not used, tighten
plug firmly.

place and lift air cleaner assembly off carburetor.
2. Move throttle control to CHOKE position and check
the position of the choke butterfly; it should be fully
closed.

of the throttle can be performed. To guard
against possible personal injury, shift into
neutral, and engage parking brake. Keep
hands, feet, face, and other parts of the body
away from the cutter blades, underside of
mower housing, discharge area, and any ro-
tating engine parts.

structions in step #3.
10. After throttle is adjusted, stop engine.
ADJUSTING CARBURETOR
The carburetor has been set at the factory, but an occa-
sional adjustment may be required. An adjustment
may be required to compensate for differences in fuel
or temperature.
IMPORTANT: Before the carburetor is adjusted,
throttle control must be checked for proper opera-
tion: refer to Adjusting Throttle—Choke Control,
page 12.
