MANUAL
624 and 824 POWER SHIFT SNOWTHROWERS J
The following instructions are comparable to the
Instructions For Safety Snowthrowing adopted
by ANSI — American National Standards Insti-
tute. The snowthrower is designed and tested
to offer reasonably safe service; however,
failure to operate it in accordance with the fol-
lowing Safety Instructions MAY RESULT IN
PERSONAL INJURY.
BEFORE OPERATING
1. Read and understand the contents of this
manual before starting and operating the
machine. Become familiar with all controls and
know how to stop the engine quickly.
2. Keep everyone, especially children and pets,
away from the area of operation. Never allow
children to operate the snowthrower.
3. Inspect area thoroughly where snowthrow-
er will be used. Remove door mats, sleds,
boards, sticks, wire and any other foreign ob-
jects which might be picked up and thrown by
the snowthrower.
4. Keep all shields and safety devices in place.
If a shield, safety device or decal is defective
or damaged, repair or replace it before opera-
tion is commenced. Also, tighten any loose nuts,
bolts and screws.
5. Wear adequate winter clothing and footwear
that will improve footing on slippery surfaces.
Do not wear loose fitting clothing that could pos-
sibly get caught in moving parts.
6. Adjust both skids so auger housing clears
gravel or crushed rock surfaces.
7. Before starting the engine, move speed con-
trol to N (neutral).
A SAFETY INSTRUCTIONS
The 624 and 824 POWER SHIFT SNOWTHROWERS meet or exceed the Outdoor Power
Equipment Institute's safety standards for snowthrowers; thus, Toro proudly displays the
OPEI safety seal. To assure maximum safety, optimum performance, and to gain knowledge
of the product, it is essential that you or any other operator of the snowthrower read
and understand the contents of this manual before the engine is ever started. Pay particular
attention to the safety symbol which means CAUTION, WARNING or DANGER — “personal
safety instruction’’. Read and understand the instruction because it has to do with safety.
Failure to comply with the instruction may result in personal injury.
8. Always use a grounded three wire plug and
cord to start snowthrower equipped with an
electric starter.
9. Fill fuel tank with gasoline before starting the
engine. Avoid spilling any gasoline. Since gaso-
line is highly flammable, handle it carefully. DO
NOT SMOKE WHILE HANDLING GASOLINE.
A. Use an approved gasoline container.
B. Fill fuel tank outdoors and only when engine
is not running. Engine must be cool to pre-
vent a potential fire hazard.
C. Open doors if engine will be run in the garage
because exhaust fumes are dangerous and
could possibly be deadly. Do not run engine
indoors.
D. Wipe up any gasoline that spilled, and install
gasoline container cap and snowthrower fuel
tank cap securely before starting the engine.
WHILE OPERATING
10. STAY BEHIND THE HANDLES AND AWAY
FROM DISCHARGE OPENING WHILE OPERAT-
ING THE SNOWTHROWER. Keep face, hands,
feet and any other part of your body or clothing
away from concealed, moving or rotating parts.
11. BEFORE ADJUSTING, CLEANING, REPAIR-
ING AND INSPECTING THE SNOWTHROWER,
AND BEFORE UNCLOGGING THE DISCHARGE
CHUTE, SHUT ENGINE OFF AND WAIT FOR
ALL MOVING PARTS TO STOP. ALSO, PULL
WIRE OFF SPARK PLUG AND KEEP WIRE
AWAY FROM THE PLUG TO PREVENT ACCI-
DENTAL STARTING. USE A STICK TO REMOVE
OBSTRUCTIONS.

SAFETY INSTRUCTIONS
12. Keep people and pets a safe distance away
from the snowthrower and area of operation.
13. Allow engine to warm up for about 2
minutes and machine to adjust to outdoor tem-
perature before clearing snow.
14. Do not run engine indoors, except when
starting engine. When starting engine indoors,
open outside doors because exhaust gasses are
dangerous.
15. Operate the snowthrower only when there
is good visibility or light. Always maintain se-
cure footing and keep a firm grip on the handles,
especially when operating in reverse.
16. Be attentive when using the snowthrower,
and stay alert for holes in the terrain and other
hidden hazards. Be careful when clearing snow
from a gravel drive because stones could be
picked up and thrown if the skids are not adjust-
ed so auger housing clears all rocks.
17. Do not make any adjustments while the en-
gine is running.
18. Never direct discharge of snow or operate
snowthrower near bystanders, glass enclosures,
automobiles and trucks, window wells or a drop-
off without proper adjustment of the snow dis-
charge angle.
19. Clear snow from slopes by going up and
down: never across the face, and use caution
when changing directions, Use lower gear and
rear wheel position when operating on slopes.
Never clear snow from steep slopes.
20. Do not overload the snowthrower by clear-
ing snow at too fast a rate.
21. If a solid object is hit or snowthrower
vibrates abnormally, shut engine off and wait for
all movement to stop. Pull high tension wire off
spark plug and check snowthrower immediate-
ly for possible damage, an obstruction or loose
parts. Vibration is generally a warning of trou-
ble. Repair any damage before restarting engine
and operating snowthrower again.
22. Do not touch engine while it is running or
soon after it is stopped because the engine will
be hot enough to cause a burn. Do not add oil
or check oil level in crankcase when engine is
running because this could be a potential hazard.
23. Before leaving the operator's position — be-
hind handles — rotate ignition key to OFF. Re-
move key from switch if snowthrower will be left
unattended.
24. Never operate snowthrower at high trans-
port speeds on slippery surfaces. Use care when
backing.
25. Let engine run for a few minutes after clear-
ing snow so moving parts do not freeze.
MAINTAINING SNOWTHROWER
26. Perform only those maintenance instruc-
tions described in this manual. Shut engine off
before performing any maintenance service or
adjustment. Additionally, pull high tension wire
off spark plug and keep wire away from plug to
prevent possibility of accidental starting. If major
repairs are ever needed, contact the local Autho-
rized TORO Service Dealer for assistance.
27. Keep snowthrower in safe operating con-
dition by keeping nuts, bolts and screws tight.
Check engine mounting bolts frequently to as-
sure they are tight.
28. Do not overspeed the engine by changing
governor settings. Recommended maximum en-
gine speed is 4000 rpm. To assure safety and
accuracy, check maximum engine speed (4000
rpm) with a tachometer.
29. Allow engine to cool before storing snow-
thrower in an enclosure such as a garage or
storage shed, and make sure the snowthrower
fuel tank is empty. Do not store snowthrower
near any open flame or where gasoline fumes
may be ignited by a spark.
30. When storing the snowthrower for an ex-
tended time — off season storage or 30 days
— drain gasoline from fuel tank to prevent a
potential hazard. Store gasoline in a safety-
approved red metal container. Remove key from
ignition switch and keep it in a memorable place.
31. At the time of manufacture, the snowthrow-
er conformed with and exceeded safety stan-
dards in effect for snowthrowers. Therefore, to
assure optimum performance and safety, pur-
chase genuine TORO replacement parts and ac-
cessories to keep the TORO all TORO. NEVER
USE “WILL-FIT” REPLACEMENT PARTS AND
ACCESSORIES. The TORO logo assures
genuineness.
32. For safety reasons, use only those acces-
sories and attachments recommended by The
TORO Company to assure continued safety cer-
tification of the product. Using unapproved ac-
cessories and attachments could contribute to
a potential hazard.
SAFETY DECALS
Safety and instruction decals are located on the snowthrower chassis and engine.

CHECK TIRE PRESSURE
IMPORTANT: Check pressure of tires because
they are over inflated at the factory for shipping.
Therefore, before the snowthrower is operated,
reduce pressure in both tires to 7-15 psi equally.
TIRE CHAINS
If snowthrower is to be equipped with optional
tire chains, wheels must be pinned to outer axle
holes,
CHECK AUGER GEAR BOX OIL (Fig. 7)
1. Move snowthrower to a level surface.
2. Remove pipe plug from gear box.
3. Check level of oil in gear box. Oil must be at
point of overflowing in filler opening.

4. If level of oil is low, add GL-5 or GL-6 SAE
85-95 EP transmission oil to the gear box until
point of overflow.
5. Install pipe plug in gear box.
PREPARATION BEFORE STARTING
FILL CRANKCASE WITH OIL (Fig. 8)
The engine is shipped from the factory without
oil in the crankcase. Therefore, before trying to
start engine, oil must be added to the crankcase.
IMPORTANT: Check level of oil every 5 operat-
ing hours or each time unit is used. Initially,
change oil after the first 2 hours of operation;
thereafter, under normal conditions, change oil
after every 25 hours of operation or annually.
1. Move unit to a level surface to assure an ac-
curate oil level reading.
2. Clean area around dipstick to prevent foreign
matter from entering filler hole when dipstick is
removed.
3. Remove dipstick from crankcase.
Figure 8
1. Dipstick
4. Slowly, pour SAE 5W-30 or SAE 10 oil into
the filler hole, using oil filler chart below, The en-
gine uses any high-quality detergent oil having
the American Petroleum Institute — API —
“Service classification” SE or SF.
Oil Fill Chart
624 Snowthrower 19 ounces of oil
824 Snowthrower 27 ounces of oil
Note: Dipstick must be fully installed to assure
accurate gauging of oil level. DO NOT OVERFILL.
FILL FUEL TANK WITH GASOLINE.
THE TORO COMPANY STRONGLY RECOM-
MENDS THE USE OF CLEAN, FRESH UNLEAD-
A 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 enclosed area. Keep
away from open flame and electrical spark,
and DO NOT SMOKE while filling the fuel
tank to prevent the possibility of an explo-
sion. Always fill fuel tank outside and wipe
up any spilled gasoline before starting en-
gine. Use a funnel or spout to prevent spill-
ing gasoline, and fill fuel tank to about 1/2
inch {13 mm) from the top of the tank, not
the filler neck.

er and keep the cap in place on the contain-
er. Keep gasoline in a cool, well-ventilated
place; never in the house. To assure volatil-
ity, 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 chil-
dren like the smell of gasoline, keep it out
of their reach because the fumes are explo-
sive and dangerous to inhale.

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 speed selector to N — neutral — and
throttle midway between SLOW and FAST
(Fig. 10).
2. Open fuel shut-off valve below fuel tank.
3. Pull choke out to half choke position when
temperature is above °F. and to full choke pos-
ition when temperature is below OF. (Fig. 10).
4. Rotate ignition key to ON (Fig. 9).
5. Push primer (Fig. 10) twice if temperature is
below 10°F. (Priming more than twice may cause
fuel to spill from carburetor).
6. Grasp recoil starter handle (Fig. 10) and pull
it out slowly until positive engagement results;
then pull vigorously to start the engine. Keep
firm grip on starter handle and return the rope
slowly.
7. After engine starts gradually push choke in
(Fig. 10).

BEFORE STOPPING ENGINE
1. Run engine for a few minutes to help dry off
any moisture which may have accumulated on
engine.
2. With engine running, pull recoil starter with
a rapid continuous full arm stroke (3) three or
(4) four times. This will help prevent possible
freeze-up of recoil starter due to extreme snow
blowing conditions.
Note: Pulling of recoil starter rope will produce
a loud clattering sound. This is not harmful to
the engine or the starter.
TO STOP ENGINE:
1. Release traction and auger/impeller drive con-
trols (Fig. 9).
2. Move speed selector to N — neutral.
3. Move throttle to slow and rotate ignition key
to OFF.
OPERATING INSTRUCTIONS
POWER SHIFT OPERATION
Move wheels rearward to the Power Shift posi-
tion in heavy and/or drifted snow.
Leave wheels in the front position for light snow
or for transporting snowthrower.
1. Release traction drive lever.
2. To move wheels to front or rear position,
move shift control fully forward to Power Shift
position and hold (Fig. 11).
Figure 11
3. Fully engage traction drive lever to move
wheels into Power Shift position (Figs. 11 & 12).
Note: When power shifting it may be necessary
to slightly raise handles to assist wheel move-
ment.
Figure 12
Note: |f wheels do not move in desired direction
when power shifting, repeat procedure. Wheels
must rotate in forward direction to move wheels
ahead and rotate rearward to move wheels back.
FREE WHEELING OR SELF PROPELLED DRIVE
The snowthrower can be free wheeled or en-
gaged for self propelled operation. When axle
pins are through outer axle holes (Fig. 13), snow-
thrower will free wheel. By contrast, when both
pins are installed through holes in wheel hub and
inner hole of axle (Fig. 13), snowthrower will
propel itself.

SNOWTHROWING TIPS
1. When snowthrower is not being used, close
fuel shut-off valve, have speed control in N —
neutral position, and key removed from the
switch.
2. Remove snow as soon as possible after it
falls. This will produce best snow removal
results.
3. When in the Power Shift position, push down
on handles to increase traction.
4. 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 11.
5. For concrete or asphalt surfaces, adjust skids
so there is 1/8 inch (3 mm) between bottom of
auger and concrete or asphalt surface.
6. Discharge snow downwind whenever possi-
ble, and overlap each swath to assure complete
snow removal. If wheels slip, shift into a lower
gear which reduces forward speed.
7. 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. DO NOT USE EXCESSIVE FORCE
AND TRY TO OPERATE THE CONTROLS WHEN
FROZEN. Free all controls and moving parts be-
fore operating.
ADJUSTING SKIDS (Fig. 14)
When snowthrower will be used on concrete or
asphalt surfaces, adjust skids using steps 1 - 2.
However, use only step 3 when snowthrower
will be used on gravel or crushed rock surfaces.
11
OPERATING INSTRUCTIONS
1. Move snowthrower to a level surface. Next,
loosen four flange screws securing both skids
to auger side plates. Skids must slide up and
down.
2. Adjust both skids so there is 1/8 of an inch
between bottom of auger and level surface.
When skids are adjusted correctly, tighten flange
nuts. Next, check 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 3
after adjusting skids for hard surfaces,
3. Loosen four flange screws 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 screws.

DRAINING GASOLINE
1. Stop engine and pull wire off spark plug.
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.
A 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.

CHANGING CRANKCASE OIL (Fig. 16)
Initially, change oil after the first 2 hours of en-
gine operation; thereafter, change oil after ev-
ery 25 hours of engine operation or annually. If
possible, run engine just before changing oil be-
cause warm oil flows better and carries more
contaminants than cold oil.
1. Pull wire off spark plug and make sure wire
does not contact plug accidentally.
2. Clean area around oil drain cap. Next, slide

ADJUSTING DRIVE CHAIN (Figs. 21-24)
The drive chain must be adjusted to maintain
1/8-3/8 of an inch deflection at mid span be-
tween transmission and axle sprocket. Check
chain deflection after every 25 hours of
operation.
1. Check deflection of chain by lifting up on
chain with moderate pressure at mid span. There
should be 1/8-3/8” deflection. If deflection is not
as specified an adjustment is required.

REPLACING SPARK PLUG (Fig. 25)
Correct spark plug to use is a NGK BP-4HS or
equivalent, and correct air gap is .025-.030 of
an inch. Since air gap between center and side
electrodes of the spark plug increases gradual-
ly during normal engine operation, install a new
plug after every 25 hours of engine operation.
1. Clean area around spark plug so foreign mat-
ter cannot fall into cylinder when plug is
removed.
2. Pull wire off spark plug and remove plug from
cylinder head.
IMPORTANT: A cracked, fouled, or dirty spark
plug must be replaced. Do not sand blast,
scrape, or clean electrodes because grit may
eventually release from the plug and fall into the
cylinder. The result will likely be engine damage.

3. Set air gap between electrodes of new spark
plug at .025-.030 of an inch (Fig. 25). Next, in-
stall spark plug in cylinder head. Tighten plug to
15 ft-lb. If torque wrench is not used, tighten
plug firmly.
4. Push the wire onto spark plug.
