SONAL SAFETY IN-
STRUCTION. Read the in-
struction because it has to
do with safety. Failure to
comply with the instruc-
tion may result in personal injury.
The following instructions are comparable to
the “Instructions for Safe Snowthrowing”
adopted by ANSI — American National Stan-
dards Institute. The snowthrower is designed
and tested to offer reasonably safe service,
provided it is operated in strict accordance
with the following Safety Instructions. Failure
to comply with these instructions MAY RE-
SULT IN PERSONAL INJURY.

A CAUTION
Read instructions on electrolyte package
before filling battery to prevent possible
accidents.
2. Fill battery cells until level of electrolyte
is over the plates, but only up to the ring at bottom
of filler neck (Fig. 18). DO NOT OVERFILL. Next,
let battery stand for about 15 minutes. During
this time, level of electrolyte may settle and fall
below the prescribed level; therefore, add electro-
lyte to any affected cell until level is up to ring
at bottom of filter neck.
IMPORTANT: Never add electrolyte to any battery
cell after battery is charged because damage to the
battery will result.
3. install vent caps on top of battery.
A CAUTION
After filling the battery cells, a small
amount of electrolyte is usually left in
the electrolyte package. This excess elec-
trolyte must be neutralized and dis-
posed safely.
Neutralize and Dispose Excess Electrolyte
Tools Required: Plastic Pail, Baking Soda, Wooden
Stick, Safety Goggles, and Rubber Gloves.
1. Put approximately one pint of water and five
heaping teaspoons of BAKING SODA into a
plastic pail.
2. Dissolve baking soda by stirring solution with
the wooden stick.
3. After baking soda is dissolved, pour excess
electrolyte into the soda-water solution. Foaming
action will result. Next, rinse inside of electrolyte
package with water; then pour the water into the
pail of soda-water. The electrolyte package is now
neutralized and can be disposed.
4. Stir solution in pail with wooden stick.
Continue to stir the solution and add more
BAKING SODA until all foaming stops. When
foaming stops electrolyte is neutralized and safe
for disposal.
5. Dispose of the solution in the pail by flushing
solution down a toilet or by pouring it down a

drain. Next, rinse the pail and wooden stick with
clean water; then dispose of the water. The pail
and stick are now neutralized.
6. Dispose of the electrolyte package and wooden
stick by putting them in a refuse container.
Charge Battery
Tools Required: 6 to 10 Amp Battery Charger
A CAUTION
Charge battery in a well-ventilated area
because gases are produced while battery
is being charged. Do not inhale the gases
because nausea may result. Also, the
gases are explosive; therefore, do not
smoke, and keep away from open flame
and electrical spark to prevent a possible
explosion. Have enough water -v.:iable
to flush electrolyte from skin and eyes,
If it is accidentally contacted. Wear
safety goggles when near a battery being
charged.
Do not connect or disconnect battery
and charger while charger is plugged into
110-120 VAC wall outlet because a spark
could possibly cause the battery to
explode. Therefore, pull charger plug
out of wall outlet before connecting or
disconnecting charger from battery
(Fig. 19).
1. Charge the battery. Using a 6 to 10 amp
charger {Fig. 19), charge battery according to the
instructions supplied by the manufacturer of the
charger. “Quick charging’ the battery is not
recommended.
Figure 19
10
2. After battery is charged, remove vent caps from
top of battery (Fig. 18). Next, check level of
electrolyte in battery cells to make sure it is up to
the ring at bottom of filler neck (Fig. 18). If level is
low, add drinking water to raise level.
3. Install vent caps on top of battery.
4. On top of the battery there are some die-cut
circles with numbers. Lift out the die-cut circles
to indicate month and year of the initial charging.
Install Battery on Mounting Plate
Tools Required: Two, 1/2-Inch Open End Wrenches
1. Set battery onto mounting plate of snow-
thrower. Battery posts must be to the outside, not
toward the fuel tank (Fig. 17). Allow about one
inch of the battery to extend over outside of
mounting plate (Fig. 17).
2. Push clamp at end of black battery cable,
which is grounded to engine, onto smallest dia-
meter, negative (-), battery post (Fig. 17). Tighten
clamp retaining nut. Next, push clamp at end of
black battery cable with red band, which is con-
nected to the solenoid, onto the largest diameter,
positive (+), battery post (Fig. 17). Tighten clamp
retarning nut.
NOTE: Battery cables must be specially routed on
and around the batte: y (Fig. 17).
3. install cover on top of battery. Next, slide
battery completely onto mounting plate. Secure
battery in place with cap screws, battery hold-down
clamps, and nuts (Fig. 17).
4. Install battery strap onto battery cover and
slide mounting ends of strap onto ends of cap
screws {Fig. 1B). Secure all parts in place with two
nuts (Fig. 16).
Check Tire Pressure
IMPORTANT: Check pressure of tires before the
snowthrower is operated. Assure that pressure in
both tires is 30 psi.
A CAUTION
For optimum performance, to gain know-
ledge of the product, and most im-
portantly, to assure maximum safety, it
is essential that you or any other opera-
tor of the snowthrower read and under-
stand the contents of this manual before
the engine is ever started.
PREPARATION BEFORE STARTING
Fill Crankcase With Oi!
Tools Required: Funnel and Clean Rag
IMPORTANT: Check level of oil every 5 operating
hours or each time snowthrower is used. Initially,
change oil after first 2 operating hours; thereafter,
under normal conditions, change oil after every 25
hours of operation. If possible, run engine just be-
fore changing oil because warm oil flows better and
carries more contaminants than cold oil.
1. Move snowthrower to a level surface. If snow-
thrower 1s tilted, level of oil will be too high or
too low.
2. Clean area around dipstick so foreign matter
does not enter filler hole when dipstick 1s removed.
Next, remove dipstick from filler neck (Fig. 20).
Figure 20
3. Slowly, pour approximately 48 ounces of any
high-quality detergent oil with “service classifi-
cation” SC, SD, SE, or MS into the filler neck.
Oil Viscosity — weight — must be selected accord-
ing to ambient temperature. Temperature/viscosity
recommendations are:
A. From +50 F to 0°F — Use SAE 5W-20 or
5W-30. SAE 10 or 10W-30 may be used if
the other oils are not available.
В. Below 0°F — Use SAE 10 or 10W-30 that
is diluted 10% with kerosene.
4. Wipe end of dipstick. Next, push dispstick
completely down into filler neck to get accurate
oil level reading (Fig. 20); then pull dipstick out
and check oil level. !f level of oil is low, add enough
oil to raise level to “F'” mark -—- full — on dipstick.
DO NOT OVERFILL.
5. Push dipstick into filler neck (Fig. 20).
Fill Fuel Tank With Gasoline
Tools Required: Clean Rag and Funnel
IMPORTANT: Do not mix oil w/gasoline because
engine damage and poor performance may result.
Do not use premium gas, white gas or gasoline
additives, Either leaded-regular or lead-free gasoline
is recommended to fill the 4 quart fuel tank.
CAUTION
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 unit is in an en-
closed area. Keep away from open flame
and electrical spark, and 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 pre-
vent spilling gasoline, and fill fuel tank
to about 1/2 inch from the top of the
tank, not the filler neck.
Store gasoline in a clean, approved con-
tainer and keep the cap in place on the
container, Keep gasoline in a cool, well-
ventilated place: never in the house. 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 gasoline, keep it out of their
reach because the fumes are explosive
and dangerous to inhale.
1. Clean area around the fuel tank cap. Remove
cap from fuel tank and fill tank to within 1/2 inch
from the top w/lead-free or leaded-reqular gasoline.
Reinstall fuel tank cap securely.
NOTE: Lead-free gasoline reduces combustion de-
posits and extends valve life, and when available,
this type of gasoline is recommended. Otherwise,
use leaded-regular gasoline.

auger and impeller, pull control up slowly until it
stops in an over center position. To disengage auger
and impeller, pull control down.
Interlock Levers (Fig. 22) One interlock lever
must be compressed against handle grip when
auger drive or wheel drive control 1s engaged. The
engine will shut off If both levers are released when
auger drive or wheel drive control is engaged. This
is a safety feature that reminds the user to dis
engage auger drive control before leaving operators
nosition behind the handles.
Wheel Clutches (Fig. 22) — Pull both wheel
clutches out to get free-wheeling characteristic. By
contrast, push both clutches in to get direct drive
to both wheels. When one wheel clutch is pushed in
and the other is out, direct drive will be to the
wheel :that has clutch pushed in: and the other
wheel wiil be free-wheeling.
Wheel Drive Control (Fig. 22) — The control has
five positions: N-—neutral, R—reverse, 1, 2, and 3.
To change speeds, move wheel drive control to
position desired. Control must be held in R--reverse
— when backing, and when it is released, gear shift
automatically returns to neutral. Use positions 1, 2,
and 3 depending on snow conditions. Keep inter-
lock lever compressed when shifting.
Throttle (Fig. 22) — The variable speed throttle
has two positions: FAST and SLOW. Moving the
throttle forward increases engine speed. Use only
enough engine speed to throw snow to the place

STARTING AND STOPPING INSTRUCTIONS
To Start Engine:
IMPORTANT: Check auger and impeller to assure
that both parts are not frozen solid, but free to
rotate. Also, make sure discharge chute is not
obstructed.
1. Move auger drive control down to DISENGAGE
(Fig. 22).
2. Move wheel drive contro! to N — neutral — and
throttle to FAST (Fig. 22).
3. Open fuel shut-off valve (Fig. 21).
4. Move choke down until it stops (Fig. 23).
5. Insert key into ignition switch (Fig. 22); then
rotate key to START position. Release key as soon
as engine starts and regulate the choke to keep
engine running. As engine warms up, move choke
fully up. Let engine warm up for a few minutes
before using snowthrower.
IMPORTANT: Do not keep starter motor engaged
for more than 8-10 seconds because the starter
motor may overheat.
NOTE: If engine does not start and temperature
is -10°F or less, rotate needle valve on carburetor
1/8 turn counterclockwise (Fig. 41). Repeat steps
4 & 5. When engine fires, move choke up slightly;
engine should start.
6. After engine starts, regulate choke and throttle
until engine runs smoothly. Allow engine to warm
up before using the snowthrower.
To Stop Engine:
1. Move wheel drive contro! to N — neutral — and
auger drive control to DISENGAGE (Fig. 22).
2. Move throttle to SLOW and rotate ignition key
counterclockwise to OFF (Fig. 22).
NOTE: Always close fuel shut-off valve after engine
is shut off. This prevents fuel from flowing from
the fuel tank and into the carburetor.
OPERATING INSTRUCTIONS
Left and Right Wheel Clutches
Before the snowthrower is started and operated,
practice using the left and right wheel clutches.
1. With snowthrower on a flat surface, push the
left or right wheel clutch in (Fig. 24). If clutch
cannot be pushed in, exert pressure on the knob
while moving opposite handle back and forth until
clutch moves down (Fig. 24). Next, push the other
whee! clutch in. If clutch cannot be pushed in,
exert pressure on the knob while moving opposite
handle back and forth until ctutch moves down.
or ATR
Figure 24

IMPORTANT: Do not use too much force when
pushing wheel clutches because damage may result.
2. When wheel clutches can be pushed in and
pulled out without trouble, move snowthrower to
an open area and start the engine.
3. With engine running at idle speed and wheel
drive control in 2 — second gear — push both
wheel clutches down (Fig. 25) to transmit power
to both wheels. MAKE SURE BOTH WHEEL
CLUTCHES ARE FULLY ENGAGED — PUSHED

OPERATING INSTRUCTIONS
4. Pull left wheel clutch out fully (Fig. 24).
The snowthrower will turn left because right wheel
is driving and left wheel is free-wheeling. Just
before turn Is completed, exert steady pressure on
left wheel clutch until it moves fully toward the
control panel. Both wheels will now drive. Do the
opposite to turn right.
5. In some conditions; a wheel clutch may not be
able to be pulled out — disengaged. |f this happens,
move wheel drive control to N — neutral position:
then pull wheel clutch out.
6. Transport — When moving snowthrower by
pushing it from one place to another, pull both
wheel clutches out so wheels are free to rotate.
Checking Safety Interlock System
The safety interlock system grounds out and stops
the engine through a series of switches (Fig. 26), if
the operator releases both interlock levers at once
before moving wheel drive control to N — neutral —
and auger drive control to DISENGAGE. So, to
keep engine running when wheel drive is in gear or
when auger drive control is ENGAGED, at least
one of the safety interlock levers (Fig. 25) must be
compressed against handle grip. This system also
prevents the operator from starting the engine with
the wheel drive control in gear or auger drive
contro! engaged.
WARNING
If interlock system does not operate
properly, have the interlock system re-
paired immediately by an Authorized
TORO Service Dealer. DO NOT TRY
TO DEFEAT THE INTERLOCK
SYSTEM BY DISCONNECTING WIRES
OR SWITCHES, OR IN ANY OTHER
WAY MAKE IT INOPERATIVE. An in-
operative interlock system will allow the
auger and impeller to rotate continuously
when operator's position is left; and
this situation is HAZARDOUS. Check
the interlock system every time snow-
thrower is used.
SWITCH
Figure 26
switch.
To Check Interlock System:
1. Push snowthrower outdoors onto a flat, open
area. Start the engine: refer to Starting and Stopping
Instructions, page 14.
2. Slowly, move auger drive control to ENGAGE
while both interlock levers are fully released.
Engine should begin to shut off; and when it does,
immediately move auger drive control back to
DISENGAGE. If engine begins to shut off, switch
is operating correctly.
3. Slowly, move wheel drive control to 1 — 151
gear — while both interlock levers are fully re-
leased. Engine should begin to shut off; and when
it does, immediately move wheel! drive control back
to N — neutral. If engtne begins to shut off, switch
Is operating correctly.
Snowthrowing Tips
1. When snowthrower is not being used, close fuel
shut-off valve, have wheel drive control in N —
neutral position, auger drive control in DISEN-
GAGE position and key removed from the ignition
2. Remove snow as soon as possible after it falls.
This will produce best snow removal results.
3. If snow will be removed from crushed rock or
gravel areas, adjust skids so bottom of auger
housing clears the rocks: refer to Adjusting Skids,
page 17,
4. For concrete or asphalt surfaces, adjust skids
so there is 1/8 inch between bottom of auger and
concrete or asphalt surface.
5, The snowthrower is designed to clean snow
down to the contact surface, but there are times
when front of snowthrower may tend to ride
up. lf this happens, reduce forward speed by shift-
ing into a lower gear. If front still tends to ride
up, lift up on both handles to hold down front of
snowthrower
6. Discharge snow downwind whenever possible,
and overlap each swath to assure complete snow
removal. If wheels slip, shift into a lower gear which
reduces forward speed.
7. Normally, chains are not required; however,
tire chains are recommended when the wheels spin
excessively,
8. In some snow and cold weather conditions,
some controls and moving parts may freeze solid.
Therefore, when any control becomes hard to
operate, stop the engine; then check all parts for
freeze up. DONOT USE EXCESSIVE FORCE AND
TRY TO OPERATE THE CONTROLS WHEN
FROZEN. Free all controls and moving parts be-
fore operating.

MAINTENANCE
CAUTION
To prevent accidental starting of the
engine while performing maintenance,
rotate ignition key to off and remove it
from the switch. Next, pull high tension
wire off spark plug (Fig. 27) and make
sure wire does not accidentally touch
the plug.

2. Push snowthrower forward so pivoting scraper
blade moves backward.
3. Adjust both skids so there is 1/8-inch between
bottom of auger and level surface. When skids are
adjusting correctly, tighten flange nuts. Next, check
pivoting scraper blade that is mounted at bottom
of auger housing. Scraper must be parallel with
level surface. If scraper is not parallel, adjust skids
again. Do not use step 4 after adjusting skids for
hard surfaces.
4. Loosen four flange nuts (Fig. 33) securing both
skids to auger side plates. Next, slide skids down as
far as possible so auger is as far from the level
surface as skid adjustment allows; then tighten
flange nuts.

Replacing Spark Plug
Tools Required: 3/4-Inch Spark Plug Socket,
Spark Plug Gapping Tool, and Clean Rag
Correct spark plug to use is a Champion RCJ-8 or
Autolite AR7N, and correct air gap is 0.030 of an
inch. Since air gap between center and side elec-
trodes of the spark plug increases gradual!y during
normal engine operation, install a new plug after
every 25 hours of engine operation.
1. Clean area around spark plug so foreign matter
cannot fall into cylinder when plug is removed.
2. Pull high tension wire off spark plug (Fig. 39);
then remove plug from cylinder head.
IMPORTANT: A cracked, fouled, or dirty spark
plug must be replaced. Do not sand blast, scrape,
or clean electrodes using a wire brush because grit
may eventually release from the plug and fall into
the cylinder. The result will likely be engine
damage.

Adjusting Carburetor
Tools Required: Screwdriver
The carburetor has been adjusted at the factory,
but an adjustment may be required if carburetor
has been disassembled. Do not make unnecessary
carburetor adjustments because factory settings
are correct for most applications.
IMPORTANT: Do not close needle valve too
tight because valve and seat in carburetor will
likely be damaged.
1. Needle Valve (Fig. 41) — Close needle valve by
gently rotating it clockwise.
2. Rotate — open — needle valve (Fig. 41) 1-1/8
turns counterclockwise.
IMPORTANT: Do not close idle valve too tight

3. Idle Valve (Fig. 41) — Close idle valve by
gently rotating it clockwise.
4. Rotate — open — idle valve (Fig. 41) 1-1/8
turns counterclockwise.
NOTE: The needle valve and idle valve settings are
approximates: however, the settings will allow
engine to be started so carburetor can be fine
tuned — steps 5 - 11.
A CAUTION
Encine must be running so final adjust-
ment of the carburetor can be perform-
ed. To guard against possible personal
injury, move auger drive and wheel drive
controls to DISENGAGE and N, and
remember to keep hands, feet, face, and
other parts of the body away from

Maintaining and Charging Battery
Tools Required: 6 to 10 Amp Battery Charger
Before charging the 12 volt battery, make sure the
battery case is not cracked. Also, remove vent
caps and look into filler holes. Top of plates
must not have ice crystals on them. {f ice crystals
are evident, do not charge the battery; take battery
indoors so it can warm up. After ice crystals are
dissolved, battery can be charged.
During normal use and storage, the battery may
discharge slowly. A partial short or leaving the snow-
thrower light on for a long time could also cause a
stow discharge of the battery. Whenever the battery
is discharged, charge it using a 6 to 10 amp charger.
Use charging instructions supplied by manufacturer
of charger.
CAUTION
Charge battery in a well-ventilated area
because gases are produced while battery
is being charged. Do not inhale the gases
because nausea may result. Also, the
gases are explosive; therefore, stay away
from open flame and electrical spark, and
do not smoke while the battery is being
charged.
1. Remove the battery; use Remove Battery From
Mounting Plate, page 8.
2. Connect battery charger cables to battery posts
(Fig. 42). Make sure that red, positive charger con-
nector is attached to positive (+) — largest diameter
— battery post (Fig. 42). The black, negative charger
connector must be attached to negative (-) —
smallest diameter — battery post (Fig. 42).
Figure 42
3. Plug power cord of charger into a grounded
110-120 volt outlet so battery can be charged
(Fig. 42).
IMPORTANT: Battery must not be in a discharged
condition during cold temperatures because battery
case could crack.
CAUTION
Do not connect or disconnect the charger
and battery when charger is plugged into
110-120 volt outlet because a spark could
possibly cause the battery to explode.
4. After battery is charged, remove power cord of

Preparing Snowthrower For Storage
1. Drain gasoline from fuel tank. Wipe up any
gasoline that may have spilled. Also clean fuel
filter. Open fuel shut-off valve.
2. Start the engine and let 1t run until it stops
because there is no gasoline in the fuel system.
When engine sputters, push choke down so fuel in
carburetor 1s expended.
3. Remove spark plug from cylinder head. Next,
pour two teaspoons of SAE 30 engine oil into spark
plug hole in cylinder head. Install spark plug in
cylinder head, but do not install high tension wire
on the plug. Then pull recoil starter slowly to
distribute oil on inside of cylinder.
4. Change otl in crankcase: use Changing Crank-
case Oil, page 16.

b. Change oil in auger gear box: use Changing
Auger Gear Box Oil, page 17.
6. Lubricate the snowthrower: use Lubricating
Snowthrower, page 16.
7. Clean the snowthrower. Touch up chipped
surfaces with paint. Sand affected areas before
painting. Use a rust preventative to prevent metal
parts from rusting.
8. Tighten all screws and nuts. If any part is
damaged, repatr or replace it.
9. Store snowthrower in a clean, dry place, and
cover it to give protection.
10. If snowthrower is equipped with the optional,
drift breaker storage bar, the snowthrower may be
stored in upright positicn (Fig. 44). However, re-
move battery from mounting plate, and make sure
to drain gas before tipping snowthrower upright.
