The left and right side of the machine is determined by standing behind the handle in the normal operator's position.

Safety

The 724 SNOWTHROWER meets or exceeds the Outdoor Power Equipment Institute's safety standards for snowthrowers; thus, Toro proudly displays the OPEI safety seal. To ensure maximum safety, best 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 alert 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 instruction may result in personal injury.

The following instructions are comparable to the Instructions For Safe Snowthrowing adopted by the American National Standards Institute (ANSI). The snowthrower is designed and tested to offer reasonably safe service; however, failure to comply with the following instructions MAY RESULT IN PERSONAL INJURY.

WARNING: Engine exhaust contains carbon monoxide which is an odorless, deadly poison. Carbon monoxide is also known to the State of California to cause birth defects. Do not run engine indoors or in an enclosed area.

Before Operating

1. Read and understand the contents of this manual before operating the snowthrower. Become familiar with all controls and know how to stop the engine quickly.

2. Keep everyone, especially children and pets, away from snowthrower and area of operation. Never allow children to operate the snowthrower. Adults should operate the snowthrower only after reading this manual.

3. Thoroughly inspect area thoroughly where snowthrower will be used. Remove doormats, sleds, boards, sticks, wire, and any other foreign objects 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 illegible, damaged or lost, repair or replace it before beginning operation. Also, tighten any loose nuts, bolts or screws.

5. Wear adequate winter clothing and rubber boots that will ensure proper footing on slippery surfaces. Do not wear loose fitting clothing that could possibly get caught in moving parts.

6. Always wear safety glasses or eye shields during operation or while performing an adjustment or repair to protect eyes from foreign objects that may be thrown from the machine.

7. Adjust both skids so auger/impeller housing clears gravel or crushed rock surfaces.

8. Before starting the engine, ensure auger/impeller drive control and traction (wheel drive) control are in disengaged position.

9. Always use a grounded three wire plug and cord to start snowthrower equipped with an electric starter. Extension cord must be connected to a properly grounded outlet.

10. Fill fuel tank with gasoline before starting the engine. Avoid spilling any gasoline. Because gasoline is highly flammable, handle it carefully. DO NOT SMOKE WHILE HANDLING GASOLINE.

A. Use an approved gasoline container.

B. Fill fuel tank outdoors, not indoors. NEVER ADD FUEL TO AN ENGINE THAT IS RUNNING OR HOT. Engine must be cool to reduce potential fire hazard.

C. Open doors if engine will be started in the garage because exhaust fumes are dangerous and could possibly be deadly. Do not run engine indoors.

D. Wipe up any spilled gasoline. Reinstall gasoline container cap and snowthrower fuel tank cap securely before starting the engine.

While Operating

1. ROTATING IMPELLER OR AUGER CAN CUT OFF OR INJURE FINGERS OR HANDS. STAY BEHIND THE HANDLES AND AWAY FROM DISCHARGE OPENING WHILE OPERATING THE SNOWTHROWER. KEEP FACE, HANDS, FEET, AND ANY OTHER PART OF YOUR BODY OR CLOTHING AWAY FROM CONCEALED, MOVING OR ROTATING PARTS.

2. BEFORE ADJUSTING, CLEANING, REPAIRING, 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 ACCIDENTAL STARTING. USE A STICK, NOT YOUR HAND, TO REMOVE OBSTRUCTIONS FROM DISCHARGE CHUTE.

3. Before leaving the operator's position—behind the handles—remove key from ignition switch.

4. Allow engine to warm up outdoors before clearing snow.

5. Operate the snowthrower only when there is good visibility or light. Always maintain secure footing and balance and keep a firm grip on the handles, especially when operating in reverse. Walk; never run.

6. 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 skids are not adjusted so auger/impeller housing clears all rocks.

7. Do not make any adjustments while the engine is running, with the exception of carburetor adjustments.

8. 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 chute and deflector angle.

9. Clear snow from slopes by going up and down, never across the face. Use caution when changing directions. Use lower gear when operating on slopes. Never clear snow from steep slopes.

10. Do not overload the snowthrower by clearing snow at too fast a rate.

11. Do not use snowthrower on a roof.

12. If a foreign object is hit or snowthrower vibrates abnormally, stop engine by turning key to OFF and wait for all moving parts to stop. Pull wire off spark plug and check snowthrower immediately for possible damage, an obstruction or loose parts. Vibration is generally a sign of trouble. Repair any damage before starting engine and operating snowthrower again.

13. 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.

14. Never operate snowthrower at high transport speeds on slippery surfaces. Use care when backing.

Maintaining Snowthrower

1. Perform only those maintenance instructions described in this manual. Shut engine off before performing any maintenance service or adjustment. Additionally, pull wire off spark plug and keep wire away from plug to prevent accidental starting. If major repairs are ever needed, contact your local Authorized TORO Service Dealer for assistance.
2. Keep snowthrower in safe operating condition by keeping nuts, bolts, and screws tight. Check engine mounting bolts frequently to assure they are tight.
3. Do not overspeed the engine by changing governor settings.
4. Never store snowthrower with fuel in fuel tank inside a building where ignition sources such as an open flame, sparks, hot water and space heaters, and clothes dryers are present. Allow engine to cool before storing in an enclosure such as a garage or storage shed. NEVER STORE SNOWTHROWER IN HOUSE (LIVING AREA) OR BASEMENT BECAUSE GASOLINE AND FUMES ARE HIGHLY FLAMMABLE, EXPLOSIVE, AND DANGEROUS IF INHALED. Do not store snowthrower near any open flame or where gasoline fumes may be ignited by a spark.
5. When storing the snowthrower for an extended 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 when storing snowthrower. Store key in a memorable place.

1. At the time of manufacture, the snowthrower conformed with or exceeded OPEI safety standards in effect for snowthrowers. Therefore, to ensure best performance and safety, purchase genuine TORO replacement parts and accessories to keep the TORO all TORO. NEVER USE “WILL FIT” REPLACEMENT PARTS AND ACCESSORIES.
2. For safety reasons, use only those accessories and attachments recommended by The TORO Company to ensure continued safety certification of the product. Using unapproved accessories and attachments could contribute to a potential hazard.

Assembly

Note: Determine left and right sides of snowthrower by standing in the normal operating position.

Install Handle

1. Remove tie straps securing control rods to handle.
2. Remove the axle pins from both wheels and slide the wheels outward on the axle approximately one inch to make clearance for assembly of handles.
3. Position left handle against side of unit, align handle mount holes with holes in side plate, and secure with two capscrews and curved washers until finger tight (Fig. 2).

Note: Concave side of curved washer goes against outside of handle.

Repeat procedure on right side. Make sure handles are at same height before tightening handle screws on both sides of unit.

1. Reinstall the wheels. Note that there are two holes in each end of the axle. Axle pins are installed through holes in the wheel hub and through inner hole of axle (Fig. 3).

Note: If snowthrower is to be equipped with optional tire chains, wheels must be pinned through outer axle holes.

Install Speed Selector Rod

1. Pull speed selector arm (Fig. 4) to the fully “out” position and move speed selector (Fig. 6) on control panel to the R (REVERSE) position to ease assembly.
2. Install speed selector rod into selector arm, add one flat washer on the selector rod and secure with cotter pin (Fig. 4).

Install Traction Rod

1. Thread a flange nut (flange side down) onto traction rod located on left handle (Fig. 5).
2. Insert traction rod through loop in lower traction rod (Fig. 5).
3. Thread a flange nut (flange side up) onto bottom of traction control rod below loop in lower traction rod (Fig. 5).
4. Adjust the two flange nuts up or down on the traction control rod until the distance between the top of the handgrip and the bottom of the traction control lever (Fig. 6 and 7) is approximately 43/8 inches. This is a preliminary setting only. Tighten the two flange nuts finger tight.
5. Move speed selector (Fig. 6) into third gear.

Note: If speed selector will not move into third gear, an adjustment is necessary: refer to Adjusting Speed Selector, page 21. Make the adjustment before continuing with assembly.

1. Slowly pull machine backward while slowly depressing traction control lever toward handle. Adjustment is correct when wheels stop turning and the distance between the top of the handgrip and the bottom of the traction control lever is one to two inches (Fig. 7). Readjust the two flange nuts, if necessary, to obtain this dimension and then tighten the two flange nuts securely.

Install Auger/Impeller Drive Control Linkage

1. Loosen jam nut above clevis on upper control rod (Fig. 8).
2. Align holes in clevis and lower control rod and insert clevis pin (Fig. 8).

3. Check the distance between the top of the handgrip and the bottom of the auger/impeller control lever (Fig. 6 & 9). Distance should be approximately four inches. This is a preliminary setting only.

4. Compress auger/impeller control lever slowly toward handgrip. The amount of force to compress the lever will increase noticeably when slack is removed from the drive belt (approximately one-half of lever movement). Adjustment is correct when the force begins to increase and the distance between the top of the handgrip and the bottom of the auger/impeller control lever is one to two inches.

Note: If force does not noticeably increase, remove the belt cover (refer to Replacing Auger/ Impeller Drive Belt, steps 1–2, page 20) and measure the one to two inch dimension above the handgrip at the point where the slack is removed from the auger/impeller drive belt.

1. To adjust the distance, remove clevis pin, loosen jam nut and thread clevis up or down to increase or decrease distance between handgrip and auger/impeller control lever (Fig. 8).
2. When adjustment is correct, install clevis pin and secure it in place with the cotter pin. Tighten jam nut to secure clevis (Fig. 8).

Install Chute Control Rod

1. Assemble chute control bracket and rod to left side of handle with capscrew and locknut. Leave locknut loose until assembly is completely mounted (Fig. 10).

2. Apply No. 2 general purpose grease to worm gear. Next, mount worm gear and bracket to mounting flange and secure with pyramidal washer and locknut (Fig. 11).

3. Slide worm gear into teeth of chute retaining ring and tighten locknut (Fig. 11).

4. Tighten the locknut securing chute control bracket against left handle (Fig. 10).
5. Check operation of chute control rod. Move worm gear slightly outward if binding is evident.

Secure Chute Deflector

1. Pivot deflector upward and back until deflector stop passes over lip on top of chute.
2. Secure left side of deflector to discharge chute using parts as illustrated in Figure 12. Make sure rubber washer and friction plate are positioned between chute and deflector and friction plate tabs fit into holes in deflector. See Figure 12 for proper installation sequence of parts.

Note: Concave side of curved washer goes against large flat washer.

1. Tighten nuts on both sides of deflector. Do not over-tighten nuts so that excessive force is required to change deflector angle.

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.

Before Starting

Fill Crankcase With Oil

The engine is shipped from the factory without oil in the crankcase. Therefore, before starting the engine, oil must be added to the crankcase.

IMPORTANT: Check level of oil every 5 operating 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, whichever comes first.

1. Move unit to a level surface to ensure an accurate 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 (Fig. 13).

4. Slowly pour 21 ounces (0.621 liters) of SAE 5W–30 or SAE 10 oil into the filler hole. The engine uses any high-quality detergent oil having the American Petroleum Institute (API) "service classification"—SE, SF or SG.

Note: Dipstick must be fully installed to ensure accurate gauging of oil level. DO NOT OVERFILL. POUR OIL SLOWLY.

DANGER

POTENTIAL HAZARD

- In certain conditions gasoline is extremely flammable and highly explosive.

WHAT CAN HAPPEN

- A fire or explosion from gasoline can burn you, others, and cause property damage.

HOW TO AVOID THE HAZARD

- Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.

- Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4" to 1/2" (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

- Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.

- Store gasoline in an approved container and keep it out of the reach of children.

- Never buy more than a 30-day supply of gasoline.

Fill Fuel Tank With Gasoline

Use clean, fresh lead-free gasoline, including oxygenated or reformulated gasoline, with an octane rating of 85 or higher. To ensure freshness, purchase only the quantity of gasoline that can be used in 30 days. Use of lead-free gasoline results in fewer combustion chamber deposits and longer spark plug life. Use of premium grade fuel is not necessary.

IMPORTANT: NEVER USE METHANOL, GASOLINE CONTAINING METHANOL, GASOHOL CONTAINING MORE THAN 10% ETHANOL, PREMIUM GASOLINE OR WHITE GAS BECAUSE ENGINE FUEL SYSTEM DAMAGE COULD RESULT.

Toro also recommends that Toro Stabilizer/Conditioner be used regularly in all Toro gasoline powered products during operation and storage seasons. Toro Stabilizer/Conditioner cleans the engine during operation and prevents gum-like varnish deposits from forming in the engine during periods of storage.

Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline.

DO NOT USE FUEL ADDITIVES OTHER THAN THOSE MANUFACTURED FOR FUEL STABILIZATION DURING STORAGE SUCH AS TORO'S STABILIZER/CONDITIONER OR A SIMILAR PRODUCT. TORO'S

STABILIZER/CONDITIONER IS A PETROLEUM DISTILLATE BASED CONDITIONER/STABILIZER. TORO DOES NOT RECOMMEND STABILIZERS WITH AN ALCOHOL BASE SUCH AS ETHANOL, METHANOL OR ISOPROPYL. ADDITIVES SHOULD NOT BE USED TO TRY TO ENHANCE THE POWER OR PERFORMANCE OF MACHINE.

1. Clean area around the fuel tank cap (Fig. 13). Remove cap from fuel tank. Using unleaded, regular gasoline, fill tank to within 1/4" to 1/2" (6 to 13 mm) from the top of the tank, not into the filler neck. This space is for expansion of fuel. Do not fill tank full. Reinstall fuel tank cap.

Operation

Controls

Auger/Impeller Drive Control (Fig. 14)—Control has two positions: ENGAGE and DISENGAGE. To engage both auger and impeller, compress lever against right handgrip. To disengage, release lever.

Traction Control (Fig. 14)—To engage traction (wheel drive), lever must be compressed against left handgrip. To stop traction, release lever.

Speed Selector (Fig. 14)—The control has four positions: reverse, 1, 2 and 3. To change speeds, move gear shift to position desired. Lever will lock in notch at each speed selection. Use positions 1, 2 or 3 depending on snow conditions.

Ignition Switch (Fig. 15)—Insert key before starting engine with the recoil starter. To stop engine, remove key.

Throttle (Fig. 15)—Moving the throttle upward increases engine speed.

Choke (Fig. 15)—Rotate choke to FULL choke position to start a cold engine. As engine warms up, move choke gradually to OFF.

Primer (Fig. 15)—Press primer to pump a small amount of gasoline into engine for improved cold weather starting.

Fuel Shut-Off Valve (Fig. 14)—Valve is located under fuel tank. Close valve by rotating it to the right to stop fuel flow from fuel tank. Open valve by rotating it to the left to allow fuel to flow to the carburetor. Close valve when snowthrower is not in use.

Discharge Chute Control (Fig. 14)—Rotate discharge chute control clockwise to move discharge chute to the left and counterclockwise to move chute to the right.

Recoil Starter (Fig. 15)—Recoil starter is on back side of engine. Pull recoil starter to start engine.

Chute Deflector Handle (Fig. 14)—Deflector handle is on top of discharge chute, and it is used to control height of the snow stream.

Starting/Stopping

If engine is operated when temperature is +40^ F ( 4^ C) or higher, remove carburetor heater box (Fig. 16). However, the heater box must be reinstalled when temperature falls below +40^ F ( 4^ C). To remove heater box:

1. Pull wire off spark plug and make sure wire does not contact plug accidentally (Fig. 16).
2. Remove (3) screws, (3) lock washers, and (3) washers securing muffler guard to engine (Fig. 16). Remove muffler guard.
3. Remove (3) Phillips screws and (1) hex head screw securing heater box in place (Fig. 16). Pull choke knob off choke rod (Fig. 15).
4. Lift heater box up and away from the engine, and reinstall choke knob on mounting pin.

To Start Engine

IMPORTANT: Check auger and impeller to ensure that both parts are not frozen but free to rotate. Also, make sure discharge chute is not obstructed. USE A STICK, NOT YOUR HAND, TO REMOVE ANY OBSTRUCTIONS.

1. Place spark plug wire on spark plug (Fig. 16).
2. Move throttle (Fig. 15) to FAST.
3. Open fuel shut-off valve below fuel tank (Fig. 14) by rotating valve to the left.

4. Rotate choke (Fig. 15) to full choke position.

5. Insert ignition key (Fig. 15).

6. Cover hole in center of primer with thumb and push primer slowly three times. DO NOT PRIME IF THE ENGINE HAS BEEN RUNNING AND IS HOT.

Note: Excessive priming may cause flooding of engine and failure to start.

1. Grasp recoil starter handle (Fig. 15) 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.

Note: If engine does not start or if temperature is -10^ ( -23^ ) or below, additional priming may be required. After each additional prime, try to start the engine before priming again.

1. After engine starts, immediately rotate choke (Fig. 15) to 3/4 position. As engine warms up, rotate choke to 1/2 position; then to OFF position. If engine falters, return choke to 1/2 position. When engine warms sufficiently, rotate choke to OFF position.

Before Stopping Engine

1. Engage auger/impeller to clear any remaining snow from inside the housing.

2. Run engine for a few minutes to help dry off any moisture which may have accumulated on engine.

3. With engine running, pull recoil starter with a rapid, continuous full arm stroke three or four times. This helps prevent possible freeze-up of recoil starter due to extreme snow blowing conditions.

Note: Pulling of recoil starter rope produces a loud, clattering sound. This is not harmful to the engine or the starter.

To Stop Engine

1. Release traction and auger/impeller drive controls (Fig. 14).

2. Move throttle to slow and remove ignition key (Fig. 15).

3. Wait for all moving parts to stop before leaving the operator's position (behind the handles).

Snowthrowing Tips

1. When snowthrower is not being used, close fuel shut-off valve by rotating valve to the right and remove key from the switch.

2. Remove snow as soon as possible after it falls. This produces best snow removal results.

3. Adjust skids to match the type of surface being cleaned; refer to Adjusting Skids, page 18.

4. The snowthrower is designed to clean snow down to the contact surface, but there are times when the front of the snowthrower may tend to ride up. If this happens, reduce forward speed by shifting into a lower gear. If front still tends to ride up, lift up on both handles to hold down front of snowthrower.

5. Discharge snow downwind whenever possible, and overlap each swath to ensure complete snow removal. If wheels slip, shift into a lower gear to reduce forward speed.

6. Run snowthrower for a few minutes after clearing snow so moving parts do not freeze. Engage auger/impeller to clear any remaining snow from inside housing.

7. Do not overload snowthrower by clearing snow at too fast a rate. If engine slows down, shift to a lower gear to reduce forward speed.

8. Always use full throttle (maximum engine speed) when throwing snow.

9. In wet or slushy conditions, clogging of the discharge chute will be reduced by maintaining maximum engine speed and by not overloading the engine.

10. In some snow and cold weather conditions, some controls and moving parts may freeze. Therefore, when any control becomes hard to operate, stop the engine and wait for all moving parts to stop; 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 before operating.

DANGER

POTENTIAL HAZARD

- When snowthrower is in operation, impeller and auger can be rotating.

WHAT CAN HAPPEN

- ROTA TING IMPELLER OR AUGER CAN CUT OFF OR INJURE FINGERS OR HANDS.

HOW TO AVOID THE HAZARD

• Before adjusting, cleaning, repairing 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 accidental starting.
• USE A STICK, NOT YOUR HANDS, TO REMOVE OBSTRUCTIONS FROM DISCHARGE CHUTE.
• Stay behind the handles and away from discharge opening while operating the snowthrower.
• Keep face, hands, feet and any other part of your body or clothing away from concealed, moving or rotating parts.

Adjusting Skids And Scraper Blade

FOR CONCRETE OR ASPHALT SURFACES

1. Pull wire off spark plug and make sure wire does

not contact plug accidentally.

1. Check the tire pressure in both tires. Make sure that they are inflated equally between 7 and 15 psi.
2. Move snowthrower to a level surface. Next, loosen (4) flange nuts securing both skids to the auger side plates (Fig. 17) until the skids can be slid up and down easily.
3. Support the auger blades off the ground so that both the scraper and the auger blades (Fig. 18) clear the level surface by at least 1/16 inch.

Note: The scraper should be higher above the pavement if the pavement surfaces on which the snowthrower will be used are cracked, rough or uneven.

1. Check the scraper blade adjustment. Scraper should be above and parallel to level surface. To adjust scraper, loosen (5) mounting screws (Fig. 18), level scraper, and retighten screws.
2. When scraper is adjusted correctly and is supported above level surface, move the skids down to sit flat on the ground and tighten the (4) flange nuts securing both skids to the auger side plates (Fig. 17). Skids will now support the auger blades and scraper above the ground.

FOR GRAVEL SURFACES

For gravel or crushed rock surfaces, adjust the skids to prevent picking up rocks.

1. Pull wire off spark plug and make sure wire does not contact plug accidentally.
2. Loosen the (4) flange nuts securing both skids to auger side plates (Fig. 17). Next, slide skids down as far as possible so auger will be supported as far from the level surface as skid adjustment allows; then tighten flange nuts.

2. Start engine and let it warm up for approximately 3 to 5 minutes; then move throttle to FAST.

WARNING

POTENTIAL HAZARD

- Engine must be running so final adjustment of the carburetor can be performed.

WHAT CAN HAPPEN

- When snowthrower is in operation, impeller and auger can be rotating.

HOW TO AVOID THE HAZARD

• Move auger/impeller drive and traction drive controls to DISENGAGE.
• Keep hands, feet, face, and other parts of your body or clothing away from muffler, auger/impeller, discharge chute, and any moving part(s).

WARNING

POTENTIAL HAZARD

• Engine exhaust contains carbon monoxide.

WHAT CAN HAPPEN

- Carbon monoxide is an odorless, deadly poison.

HOW TO AVOID THE HAZARD

- Do not run engine indoors or in an enclosed area.

1. Rotate power adjusting screw (Fig. 29) clockwise—in—1/8 turn at a time until engine misses because of a lean gasoline mixture. Then rotate screw counterclockwise—out—1/8 turn at time until engine runs unevenly because of a rich gasoline mixture. Next, rotate power adjusting screw clockwise, back to the midpoint between the rich and lean settings, so engine runs smoothly.

Note: Wait several seconds between each 1/8 turn setting so engine can adjust to the new fuel mixture.

1. Move throttle to idle speed. Next, rotate idle speed screw until engine idles fast—1750 rpm.

2. Rotate idle mixture screw (Fig. 29)

clockwise—in—1/8 turn at a time until engine begins to miss because of a lean mixture. Then rotate screw counterclockwise—out—1/8 turn at a time until engine runs unevenly because of rich mixture. Next, rotate idle mixture screw clockwise, back to the mid-point between rich and lean settings.

Note: W ait several seconds between each 1/8 turn setting so engine can adjust to the new fuel mixture.

1. Again, rotate idle speed screw (Fig. 29) until engine idles at 1750 rpm.
2. Check carburetor adjustment by quickly moving throttle from low speed to high speed. Engine should accelerate without hesitation or sputtering. If engine does not accelerate properly, adjust carburetor to a slightly richer mixture. Also, if engine falters under load, open power adjusting screw 1/8 turn counterclockwise.
3. After carburetor is adjusted, shut engine off before reinstalling carburetor heater box and muffler guard.
4. Reinstall choke knob on mounting pin.

Replacing Spark Plug

Use a Champion RJ–19LM spark plug or equivalent. Set air gap at 0.030" (0.76 mm). Check spark plug yearly or every 100 operating hours. If electrodes in center of plug are dark or have deteriorated, install a new plug.

1. Clean area around spark plug so foreign matter cannot fall into cylinder when plug is removed.
2. Pull wire off spark plug (Fig. 16) 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.

1. Set air gap between electrodes of new spark plug at 0.030" (0.76 mm) (Fig. 30). Next, install spark plug in cylinder head. Tighten plug to 15 ft–lb (20.4 N·m).
2. Push the wire onto the spark plug (Fig. 16).

Preparing Snowthrower For Storage

1. FUEL SYSTEM PREPARATION-

Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline.

• Add Toro Stabilizer/Conditioner to the fuel tank (one ounce per gallon of fuel).
• Run engine for ten minutes to distribute conditioned fuel through fuel system.
• Stop engine, allow it to cool, and drain fuel tank or run engine until it stops.
• Restart the engine again and run it until it stops.
• Either choke or prime the engine, restart it a third time and run engine until it will not restart.
• Dispose of fuel properly. Recycle per local codes.
  • DO NOT store ST ABILIZED gasoline over 90 days.
• Remove spark plug from cylinder head. Next, pour two teaspoons of engine oil into spark plug hole in cylinder head. Install spark plug in cylinder head, but do not install wire on the plug. Then pull recoil starter slowly to distribute oil on inside of cylinder.

• Lubricate the snowthrower: refer to Lubricating Snowthrower, page 19. Change crankcase oil: see Changing Crankcase Oil, page 19.

• Clean the snowthrower. Touch up chipped surfaces with paint. Toro Re-Kote paint is available from an Authorized TORO Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent metal parts from rusting.

• Tighten all screws and nuts. If any part is damaged, repair or replace it.

• ST ORE SNOWTHROWER—Cover

snowthrower and store in a clean, dry place out of the reach of children. NEVER STORE SNOWTHROWER IN HOUSE (LIVING AREA) OR BASEMENT WHERE IGNITION SOURCES MAY BE PRESENT SUCH AS HOT WATER AND SPACE HEATERS, CLOTHES DRYERS, AND THE LIKE BECAUSE GASOLINE AND FUMES ARE HIGHLY FLAMMABLE, EXPLOSIVE, AND DANGEROUS IF INHALED. Allow engine to cool before storing in any enclosure.
