FORM NO. 3315-304 (— MODEL NO. 38052 — 3900001 & UP OPERATOR'S a MANUAL \— 521 SNOWTHROWER 4) SAFETY INSTRUCTIONS The 521 SNOWTHROWER meets or exceeds the Outdoor Power Equipment Institute’s safety stan- dards for snowthrowers; thus, Toro proudly displays the OPE! safety seal. To ensure maximum safe- ty, best performance, and to gain knowledge of the product, it is essential that you or any other oper- ator 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 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. rr dE À which means CAUTION, WARNING OR The following instructions are comparable to the in- structions For Safe Snowthrowing adopted by the American National Standards Institute (ANSI). The snowthrower is designed and tested to offer reason- ably safe service; however, failure to comply with the following instructions MAY RESULT IN PERSONAL INJURY. WARNING: Engine exhaust contains carbon monox- ide 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 manu- al before operating the snowthrower. Become famil- iar 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. Nev- er allow children to operate the snowthrower. Adults should operate the snowthrower only after reading this manual. 3. 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. Adjust both skids so auger housing clears gravel or crushed rock surfaces. 7. Before starting the engine, ensure auger drive control and traction (wheel drive) control are in dis- engaged position. 8. Always use a grounded, three wire plug and cord to start snowthrower equipped with an electric starter Extension cord must be connected to a prop- erly gro..nded outlet. 9. Fill fuel tank with gasoline before starting the en- gine. 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. Fil ‘ual tank outdoors not indoors. NEVER ADD FUEL TO AN ENGINE THAT IS RUNNING OR HOT Engine must be cool to reduce potential fire azard, C. Open doors if engine will be started in the ga- rage because exhaust fumes are dangerous and could possibly be deadly. Do not run engine in- docs. D. Wipe up any spilled gasoline. Reinstall gasoline cortainer cap and snowthrower fuel tank cap securely before starting the engine. WHILE OPERATING 10. ROTATING IMPELLER OR AUGER CAN CUT OFF OR INJURE FINGERS OR HANDS. STAY BE- HIND THE HANDLES AND AWAY FROM DIS- CHARGE 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. 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 ACCIDENTAL STARTING. USE A STICK, NOT YOUR HAND, TO REMOVE OBSTRUCTIONS FROM DISCHARGE CHUTE. ©The Toro Company - "392 TPS 12. Before leaving the operator's position—behind the handles—rotate ignition key to OFF and wait for all moving parts to stop. Remove key from switch if snowthrower will be left unattended. 13. Allow engine to warm up outdoors before clearing snow. 14. 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. 15. 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 housing clears all rocks. 16. Do not make any adjustments while the engine is running. 17. 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. 18. Clear snow from slopes by going up and down, never across the face. Use caution when changing directions. Use lower gear when operat- ing on slopes. Never clear snow from steep slopes. 19. Do not overload the snowthrower by clearing snow at too fast a rate. 20. DO NOT USE SNOWTHROWER ON A ROOF. 21. If a foreign object is hit or snowthrower vi- brates abnormally, stop engine by turning key to OFF and wait for all moving parts to stop. Pull wire off spark plug and check snowthrower imme- diately 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. 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. 23. Never operate snowthrower at high transport speeds on slippery surfaces. Use care when back- ing. A) SAFETY INSTRUCTIONS MAINTAINING SNOWTHROWER 24. Perform only those maintenance instructions described in this manual. Shut engine off before performing any maintenance service or adjust- ment. Additionally, pull wire off spark plug and keep wire away from plug to prevent accidental starting.

Therefore, before the snowthrower is operated, reduce pressure in both tires to 7-15 psi equally. BEFORE OPERATING 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; thereaf- ter, under normal conditions, change oil after every 25 hours of operation or annually, which- ever comes first. 1. Move unit to a level surface to ensure 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 (Fig. 13). 4. Slowly pour 21 ounces (0.621 liters) of SAE 5W-30 or SAE 10 oil into the filler hole. The en- gine uses any high-quality detergent oil having the American Petroleum Institute (API) “service classi- fication”—SE, SF or SG. Note: Dipstick must be fully installed to ensure accurate gauging of oil level. DO NOT OVERFILL. —— —— — | UN — ZN al Figure 13 1. Filler hole 2. Dipstick 3. Fuel tank cap space is for expansion of fuel. 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. 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. Do not fill tank full. Fill fuel tank to about 1/4” to 1/2” (6 to 13 mm) from the top of the tank, not into the filler neck. This Store gasoline in a clean, approved container 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. it. Do FILL FUEL TANK WITH GASOLINE THE TORO COMPANY STRONGLY RECOMMENDS THE USE OF CLEAN, FRESH UNLEADED REGULAR GASOLINE IN TORO GASOLINE POWERED PROD- UCTS. UNLEADED GASOLINE BURNS CLEANER, EXTENDS ENGINE LIFE, AND PROMOTES GOOD STARTING BY REDUCING THE BUILDUP OF COM- BUSTION CHAMBER DEPOSITS. LEADED GASOLINE CAN BE USED IF UNLEADED IS NOT AVAILABLE. IMPORTANT: NEVER USE METHANOL, GASOLINE CONTAINING METHANOL, GASOHOL CONTAIN- ING MORE THAN 10% ETHANOL, PREMIUM GASOLINE OR WHITE GAS BECAUSE ENGINE FUEL SYSTEM DAMAGE COULD RESULT. Toro also recommends that Toro Stabilizer/Condi- tioner be used regularly in all Toro gasoline pow- ered products during operation and storage sea- sons. Toro Stabilizer/Conditioner cleans the engine 10 during operation and prevents gum-like varnish deposits from forming in the engine during periods of storage. 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. 1. Clean area around the fuel tank cap (Fig. 13). Remove cap from fuel tank. Using unleaded, regu- lar gasoline, fill tank to within 1/4” to 1/2" (6 to 13 mm) from the top of the tank, not into the filer neck. This space is for expansion of fuel. Do not fill tank full. Reinstall fuel tank cap. CONTROLS Auger Drive Control (Fig. 14)—Control has two po- sitions: 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 posi- tions: 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 de- pending on snow conditions. Choke (Fig. 15)—Rotate choke to FULL choke posi- tion to start a cold engine. As engine warms up. move choke gradually to OFF.

However, the heater box must be reinstalled when temperature falls below +40° F (4° C). To remove heater box: A. Remove (2) phillips screws and (1) hex head screw securing heater box in place (Fig. 16). Pull choke knob off choke rod (Fig. 15). B. Lift heater box up and away from the engine, and reinstall choke knob on mounting pin. Figure 16 1. Carburetor heater box 3. Hex head screw 2. Phillips screws IMPORTANT: Check auger and impeller to ensure that both parts are not frozen but free to rotate. Also, make sure discharge chute is not ob- structed. USE A STICK, NOT YOUR HAND, TO R Y T ! 1. Move throttle (Fig. 15) to FAST. 2. Open fuel shut-off valve below fuel tank (Fig. 14). 3. Rotate choke (Fig. 15) to full choke position. 4. Rotate ignition key (Fig. 14) to ON. 12 5. 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. 6. 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° Е (-23° C) or below, additional priming may be required. After each additional prime, try to start the engine before priming again. 7. 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 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 en- gine. 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 condi- tions. 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 drive controls (Fig. 14). 2. Move throttle (Fig. 15) to slow and rotate igni- tion key (Fig. 14) to OFF. 3. Wait for all moving parts to stop before leaving the operator's position (behind the handles). OPERATING INSTRUCTIONS SNOWTHROWING TIPS 1. When snowthrower is not being used, close fuel shut-off valve 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 be- ing cleaned; refer to Adjusting Skids, page 13. 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 clear- ing snow so moving parts do not freeze. Engage auger 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. ® ROTATING IMPELLER OR AUGER CAN CUT QFF OR INJURE FINGERS OR HANDS. STAY BEHIND THE HANDLES AND AWAY FROM DIS- CHARGE OPENING WHILE OPERATING THE SNOWTHROWER. KEEP FACE, HANDS, FEET AND ANY OTHER PART OF YOUR BODY OR CLOTHING AWAY FROM CONCEALED, MOV- ING OR ROTATING PARTS. e 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 ACCI- DENTAL STARTING. USE À STICK, NOT YOUR HANDS, TO REMOVE OBSTRUCTIONS FROM ISCHAR HUTE. 10. In some snow and cold weather conditions, some controls and moving parts may freeze. Therefore, when any control becomes hard to op- erate, 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 OP- ERATE THE CONTROLS WHEN FROZEN. Free all controls and moving parts before operating. 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. 2. Check the tire pressure in both tires. Make sure that they are inflated equally between 7 and 15 psi. 3. Move snowthrower to a level surface. Next, loosen (4) flange nuts securing both skids to the auger side plates (Fig. 17). Skids must slide up and down. Vo Ne — Figure 17 1. Skid 2. Auger side plate 3. Flange nuts 4. Support the auger blades off the ground so that both the scraper and the auger blades (Fig. 18) clear the leve! 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. |- ! ; + / Figure 18 1. Scraper 3. Auger blades 2. Mounting screws 13 OPERATING INSTRUCTIONS 5. Check the scraper blade adjustment. Scraper should be above and parallel to level surface. To adjust scraper, loosen (5) mounting screws, level scraper, and retighten screws. 6. When scraper is adjusted correctly and is sup- ported 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. Skids will now support the auger nlades 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. Next, slide skids down as far as possible so auger will be supported as far from the level surface as skid adjustment allows; then tighter flange nuts. MAINTENANCE while performing maintenance, rotate ignition key to off and remove it from the switch. Next, pull wire off spark plug and make sure wire does not accidentally touch the plug. DRAINING GASOLINE 1. Close fuel shut-off valve locatec under fuel tank (Fig. 19). не 5 Mr ab ef Figure 19 1. Fuel shut-off valve 2. Hose clamp 3. Fuel line à WARNING 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.

Puil wire off spark plug and make sure wire does not contact plug accidentally. 2. Drair gasoline from fuel tank; refer to Draining Gasoline page 14. 3. Tip srowthrower forward onto auger housing and block :t so it cannot fall. Now, remove four screws Foiding bottom cover in place and remove 20). cover (Fy Figure 20 1. Screws 4. Lightly iubricate snowthrower with light oil and grease as shown in Figure 21. Wipe up any ex- cess ol 11° grease. MAINTENANCE | IMPORTANT: Do not get oil or grease on rubber wheel or friction drive plate because the wheel will slip and the rubber may deteriorate. 5. Reinstall bottom cover with (4) screws. CHANGING CRANKCASE OIL Initially, change oil after the first 2 hours of engine operation; thereafter, under normal conditions, change oil after every 25 hours of engine opera- tion or annually, whichever comes first. If possible, run engine just before changing oil because 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. Block up the rear of the snowthrower chassis and remove the left wheel. 3. Clean area around oil drain plug. Next, slide oil drain pan below drain extension: then remove oil drain plug (Fig. 22). Figure 22 1. Drain plug 4. After all oil is drained, reinstall oil drain plug and left wheel. 5. Position snowthrower on a level surface. Next, fill! crankcase with oil: refer to Fill Crankcase With Qil, page 10. Wipe up any oil that may have spilled. AUGER GEAR BOX The auger gear box is filled with grease at the fac- tory so regular maintenance is not required.

Agair, rotate idle speed screw (Fig. 29) until engine idies at 1750 rpm. 9. Chec« carburetor adjustment by quickly mov- ing throtte from low speed to high speed. Engine should accelerate without hesitation or sputtering. If engine does not accelerate properly, adjust car- buretor ty a slightly richer mixture. Also, if engine falters urder load, open power adjusting screw 1/8 turn courterclockwise. 10. After carburetor is adjusted, shut engine off betore replacing carburetor heater box. REPLACING SPARK PLUG Use a Crampion RJ-19LM spark plug or equiva- lent. Set air gap at 0.030" (0.76 mm). Since air gap between center and side electrodes of the spark plug increases gradually during normal sn- gine ope: ation, install a new plug after every 25 hours of engine operation. 1. Clear area around spark plug so foreign mat- ter cannct fall into cylinder when plug is removed. 2. Pull wire off spark plug (Fig. 30) and remove plug for 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. Figure 30 1. Spark plug wire 3. Set air gap between electrodes of new spark plug at 0.C30" (0.76 mm) (Fig. 31). Next, install spark plug in cylinder head. Tighten plug to 15 ft-Ib (20 4 N.m). 4. Push te wire onto the spark plug (Fig. 30). MAINTENANCE 110 Figure 31 PREPARING SNOWTHROWER FOR STORAGE 1. For long term storage, either drain gasoline from fuel tank or use a fuel additive before stor- ing. To drain gasoline, refer to Draining Gasoline, page 14. After fuei is drained, start engine and let it idle until all fuel is consumed and engine stops. Repeat the starting procedure two more times to ensure all gas is removed from the engine. If gasoline is not drained, gum-like varnish deposits will form and cause poor engine operation and 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 distil- late based conditioner/stabilizer. Toro does not recommend stabilizers with an alcoho! base, such as ethanol, methanol or isopropyl. Use fuel addi- tive in recommended quantities as specified on container. Under normal conditions, fuel additives remain ef- fective in fuel for 6-8 months. 2. Remove spark piug 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 3. Lubricate the snowthrower: refer to Lubricating Snowthrower, page 14. Change crankcase oil: see Changing Crankcase Oil, page 15. 4. Clean the snowthrower. Touch up chipped sur- faces with paint. Toro Re-Kote paint is available from an Authorized TORC Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent metal parts from rusting. 5. Tighten all screws and nuts. If any part is damaged repair or replace it. 6. Store snowthrower in a clean, dry place, and cover it ‘or protection. IDENTIFICATION AND ORDERING MODEL AND SERIAL NUMBER The snowthrower has two identification numbers: a model number and a serial number. The two num- bers are stamped on a decal which is located on back of engine mounting plate. In any correspon- dence concerning the snowthrower. supply model and serial numbers to ensure that correct informa- tion and replacement parts are obtained. UPL-56470 To order replacement parts from an Authorized TORO Service Dealer, supply the following informa- tion: 1. Mode! and serial numbers of the snowthrower. 2.
