BEFORE OPERATING
FILL CRANKCASE WITH OIL
The engine does not have oil in the crankcase when
it is shipped from the factory. If engine is started
before 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
foreign matter from entering the filler hole when
dipstick is removed.
3. Remove dipstick by rotating cap counterclock-
wise (Fig. 10).
1. Dipstick
4. Slowly pour approximately 48 ounces of oil into
the filler neck. The engine uses any high quality
detergent oil having the American Petroleum Institute
— API — “service classification” SF, SC, SD or SE.
The recommended oil to use is: SAE 30, 10W30 or
10W-40.
5. Wipe end of dipstick with clean rag and insert
it into filler neck. Rotate cap clockwise. Then
remove the dipstick and check level of oil by
reading the dipstick (Fig. 9). If level of oil is low,
add only enough oil to raise level to FULL mark on
dipstick. 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 rotate cap
clockwise to lock.
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 conditions are normal, change oil
after every 25 hours of operation. However, change
oil more frequently when mower is operated in
dusty or dirty conditions.

FILL FUEL TANK WITH GASOLINE
THE TORO COMPANY STRONGLY RECOMMENDS
THE USE OF CLEAN, FRESH UNLEADED REGULAR
GASOLINE IN TORO GASOLINE POWERED
PRODUCTS. UNLEADED GASOLINE BURNS
CLEANER, EXTENDS ENGINE LIFE, AND PROMOTES
GOOD STARTING BY REDUCING THE BUILD-UP OF
COMBUSTION CHAMBER DEPOSITS. LEADED
GASOLINE CAN BE USED IF UNLEADED IS NOT
AVAILABLE.
NOTE: NEVER USE METHANOL, GASOLINE CON-
TAINING METHANOL, GASOHOL CONTAINING
MORE THAN 10% ETHANOL, GASOLINE ADD!-
TIVES, PREMIUM GASOLINE, OR WHITE GAS
BECAUSE ENGINE FUEL SYSTEM DAMAGE
COULD RESULT.
1. Clean area around fuel tank cap and remove
cap from tank.
2. Fill fuel tank to within 1/2 inch (12.7 mm) from
top of the tank with gasoline. Install fuel tank cap
securely.
3. Wipe up spilled gasoline.
Because gasoline is flammable, caution
must be used when storing or handling
it. 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
possibility 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, and fill tank to about 1/2 inch
(12.7 mm) below the filler neck. Store
gasoline in a clean safety-approved
container and keep the cap in place on
the container. Keep gasoline in a cool,
weli-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 combustion 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.
CHECK TIRE PRESSURE
Tires are over inflated at the factory. Check tires
and insure they are inflated to 24 psi.

SD, SE, or SF engine oil. Recommended
viscosity of oil to use is SAE 30, 10W30
or TOW40.
FUEL FILTER REPLACEMENT
An in-line filter is incorporated into the fuel line
between the fuel tank and carburetor (Fig. 17).
Use the following procedures should replacement
become necessary:
Figure 17
1. Hose clamps
1. 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 re-
maining 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 gasoline fumes may be
ignited by a spark. Do not smoke a
cigar, cigarette, or a pipe when handling
gasoline.
12
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
operation of the engine, check condition of
electrodes after every 25 operating hours. Recom-
mended air gap is 0.030 of an inch (0.762 mm).
Correct spark plug to use is:
Champion RCJ:8 or Autolite AR7N.
Note: The spark plug usually lasts a long time;
however, 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 re-
moved.
2. Pull high tension wire off spark plug and re-
move plug from cylinder head.
3. Check condition of side electrode, center
electrode, and center electrode insulator to assure
there is no damage.
IMPORTANT: A cracked, fouled, dirty or mal-
functioning 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.
5. Set air gap between center and side electrodes
at 0.030 of an inch (0.762 mm) (Fig. 18). Install
correctly gapped spark plug w/gasket seal, and
tighten plug to 15 ft-lb (20.4 N-m). If torque
wrench is not used, tighten plug firmly.

4. If the choke butterfly is positioned as described
in steps 2 and 3, replace the air cleaner assembly
and continue operation.
If either the choke butterfly does not close or
is not fully open in the FAST position, adjust
the remote control lever as follows:
1. Place remote control lever in CHOKE position.
2. Loosen the throttle cable clamp screw (Fig. 19)
and move the control cable casing and wire until
the throttle lever touches link.
3. Tighten the cable clamp and assemble the air
cleaner cover to the air cleaner.
ADJUSTING CARBURETOR
The carburetor has been set at the factory, but an
occasional adjustment may be required. An adjust-
ment may be required to compensate for dif-
ferences in fuel, temperature and altitude.
IMPORTANT: Before the carburetor is adjusted,
throttle control must be checked for proper
operation: refer to Adjusting Throttle/Choke
Control, page 13.
1. Needle Valve (Fig. 20) — Close valve by gently
rotating it clockwise.
IMPORTANT: Do not close the needle valve too
tight because the valve and seat in carburetor will
likely be damaged.
2. Rotate — open — the needle valve 2 turns
counterclockwise (Fig. 20).

2. Idle speed adjusting screw
3. Needle valve
Note: The needle valve setting is an approximate;
however, the setting will allow engine to be started
so carburetor can be fine tuned — steps 3-9.
WARNING
Engine must be running so final ad-
justment of the carburetor can be per-
formed. To guard against possible per-
sonal injury, move deck engagement
switch into OFF position, 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 rotating engine parts.
3. Start engine and let it warm up for approxi-
mately two minutes. Next, move throttle control
into FAST detent.
IMPORTANT: Air cleaner must be installed on the
engine whenever high speed is being adjusted. The
air cleaner mounting screw must also be installed
when engine is run.

MAINTENANCE
4. Rotate needle valve (Fig. 20) clockwise, 1/8
turn at a time, until engine starts to lose speed. Let
engine react to each 1/8 turn setting.
5. Rotate needle valve (Fig. 20) counterclockwise
— out — 1/8 turn at a time, until engine first runs
rough. Let engine react to each 1/8 turn setting.
6. Rotate needle valve (Fig. 20) clockwise — in —
very slowly until engine starts to run smoothly.
This setting, under no load, may be slightly rich:
however; the slightly rich setting will assure proper
operation when engine is under load.
7. Move throttle control backward so engine idles.
If engine stalls, rotate idle adjusting screw until
engine speed increases (1750 rpm).
Note: Rotate idle adjusting screw clockwise to
increase idle rpm. By contrast, rotate idle adjusting
screw counterclockwise to decrease idle rpm.
8. Turn idle valve in (lean) and out (rich) slowly
until engine idles smoothly. | |
9. Check carburetor adjustment by quickly mov-
ing throttle control from SLOW to FAST. En-
gine speed should increase without hesitation. If
engine tends to stall or die out, rotate needle valve
1/8 turn counterclockwise until engine accelerates
smoothly.
10. After carburetor is adjusted, shut engine off.
ADJUSTING AND REPLACING TRACTION
BELT
1. Loosen capscrew and flange nut securing idler
pulley to frame (Fig. 21). Slide pulley outward
relieving belt tension.

2. Remove left front engine mounting bolt
securing clutch retainer to frame (Fig. 21). Unhook
retainer from clutch and remove retainer.
3. Disconnect in-line wire connector and remove
belt from drive pulley and clutch (Fig. 21).
4. Install new belt around clutch and drive pulley.
5. Secure in-line connectors and reinstall clutch
retainer to clutch and frame with engine mounting
bolt. Torque engine mounting bolt to 170-220
in.-Ib.
6. Position and secure idler pulley to frame so belt
deflection is no more than 11/64” when 5-1/2 Ib
force is applied to midspan of long leg of belt (Fig. 21).
ADJUSTING CLUTCH
The clutch is adjustable to ensure proper engage-
ment and proper braking.
1. To adjust clutch, tighten or loosen locknuts on
flange studs (Fig. 21).
2. Check adjustment by inserting feeler gauge thru
slots next to flange studs.
3. The proper disengaged clearance between the
clutch plates is .012 - .018 inches. It will be neces-
sary to check this clearance at each of the three slots
to ensure the plates are parallel to each other.
BRAKE ADJUSTMENT
An adjustment to the brake may be required to
compensate for belt stretching or brake seating.
1. To adjust brakes, refer to Install Control Rod,
page 7.
DRIVE BELT REPLACEMENT
1. Remove top capscrew securing idler support
and idler bracket to rear frame (Fig. 22).
2. Loosen bottom two mounting screws enough
to allow belt to pass between.drive pulley and idler
support (Fig. 22).
3. Raise wheel off ground enough to allow belt
removal.

CLEANING COOLING SYSTEM
Clean cooling system frequently. Remove build-up of
grass, dirt or other debris from the cylinder and
cylinder head cooling fins, air intake screen on
flywheel end, and carburetor-governor levers and
linkage. This will help insure adequate cooling and
correct engine speed and reduce the possibility of
overheating and mechanical damage.
