BEFORE OPERATING
A) 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.
MIX GASOLINE AND OIL (Fig. 6)
This product uses a two—cycle engine which requires
a mixture of gasoline and two—cycle oil (50:1 gas/oil
ratio). Failure to use proper fuel mixture will cause
serious engine damage.
1. OlL—For optimum performance, use Toro Two—
Cycle Oil. If Toro Two—Cycle Oil is not available, use
another high grade two—cycle oil that has the NMMA
or BIA—TCW certification printed on the label. Mix
fresh, unleaded gasoline and oil as specified in the
chart below. Leaded regular gasoline can be used if
unleaded is not available.
NEVER USE AUTOMOTIVE OIL (i.e. SAE 30, 10W30
etc.), TWO—CYCLE OIL THAT IS NOT CERTIFIED
NMMA/BIA—TCW OR THE WRONG MIX RATIO BE-
CAUSE THE ENGINE CAN BE DAMAGED, AND IT
WOULD NOT BE COVERED BY WARRANTY.
4
2. Mixing Gasoline and Oil—Pour correct amount of
two cycle oil into an approved gasoline container and
add a small amount of gasoline (see following chart
for correct measurements). Install cap on gasoline
container and shake the container to mix oil and gas
thoroughly. Remove cap and add remaining amount
of gasoline.
Toro also recommends that Toro Stabilizer/Condition-
er be used regulariy 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: NEVER USE METHANOL, GASOLINE
CONTAINING METHANOL, GASOHOL CONTAIN-
ING MORE THAN 10% ETHANOL, PREMIUM GAS-
OLINE, OR WHITE GAS BECAUSE 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 STA-
BILIZER/CONDITIONER OR A SIMILAR PRODUCT.
TORO’S STABILIZER/CONDITIONER IS A PETRO-
LEUM DISTILLATE BASED CONDITIONER/STABI-
LIZER. TORO DOES NOT RECOMMEND STABILIZ-
ERS WITH AN ALCOHOL BASE SUCH AS ETHA-
NOL, METHANOL OR ISOPROPYL. ADDITIVES
SHOULD NOT BE USED TO TRY TO ENHANCE
THE POWER OR PERFORMANCE OF MACHINE.
NOTE: Do not mix gasoline and oil in the product fuel
tank. Oil that is at room temperature mixes easier and
more thoroughly than cold oil.

OPERATING INSTRUCTIONS
OPERATING TIPS
1. CUTTING AND BAGGING—Best results are
achieved when only about 1/3 of the grass blade is
cut. Iflong grass must be cut, use highest height—
of—cut setting (E) 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.
2. SHARP BLADE— Begin each cutting season with a
sharp blade. Periodically file down nicks.
STARTING, STOPPING, AND SELF—PROPELLING
CONTROLS—Throttle and self—propel control bar
(self-propelled model) are on upper handle (Fig. 7).

4. INSPECTING BLADE—Carefully examine blade for
sharpness and wear, especially where fiat and curved
parts meet (Fig. 22A). 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. 22B
& C), replace blade with a new TORO blade. Refer to
step 5.
Note: For best performance, install a new TORO
blade before cutting season begins. During the year,
file down small nicks to maintain the cutting edge.

6. SHARPENING BLADE—Using a file, sharpen top
side of blade (side facing top of mower housing) and
maintain original cutting angle (Fig. 24). The blade
remains balanced if the same amount of material is
removed from both cutting edges.
MAINTENANCE
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.

cup, (2) washers, and (2) blade nuts. Sail part of
blade must point toward top of mower housing to
assure correct installation. Tighten blade nuts to
20-35 N.m (15—25 ft—Ib).
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 out-
side of all wheel bolts. Spin wheels to distribute oil
into bushings. Wipe up excess oil.
2. SELF—PROPELLED MODEL only—Drain gasoline;
refer to Draining Gasoline, page 8.
3. Set mower to highest height—of—cut setting (E).

CLEANING MOWER HOUSING
To assure optimum performance, keep underside of
mower housing and inside of discharge area clean.
1. Drain gasoline from fuel tank: refer to Draining
Gasoline, page 8.
2. Tip mower on its right side (Fig. 26). Avoid rotating
blade because starting problems may result.
Figure 26
3. Remove dirt and grass clippings that stick to
housing by spraying it with a garden hose. Scrape
out remaining debris with hardwood scraper. Avoid
burrs and sharp edges.
4. Clean discharge door and hinges of grass or de-
bris that may impair operation of door.
PREPARING MOWER FOR STORAGE
1. For long term storage, either drain gasoline from
fuel tank or use a fuel additive before storing. To drain
gasoline, refer to Draining Gasoline, page 8. After
fuel is drained, start engine and let it idle until all fuel
is consumed and engine stops. Repeat the starting
procedure two more times to assure all gas is re-
moved from the engine. If gasoline is not drained,
gum-like varnish deposits will form and cause poor
engine operation, 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, all fuel additives remain
effective in fuel for 6-8 months.
2. 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 20.4 N-m (15 ft—Ib). DO NOT IN-
STALL WIRE ON SPARK PLUG.
3. Clean mower housing; refer to Cleaning Mower
Housing, page 11.
