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 alert symbol А 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 compara- ble to the Instructions For Safety 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 Safety Instructions MAY RESULT IN PERSONAL INJURY. 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 en- gine quickly. 2. Keep everyone, especially children and pets, away from area of operation. Never 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 or damaged, 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 assure secure 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, move speed shift control to N (neutral). 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 gasoline is highly flam- mable, handle it carefully. DO NOT SMOKE WHILE HANDLING GASOLINE. A. Use an approved gasoline container. ©The Toro Company-1988, Rev. 1989 A\ SAFETY INSTRUCTIONS B. Fill fuel tank outdoors, not indoors. NEVER ADD FUEL TO AN ENGINE THAT IS RUNNING OR HOT. Engine must be cool to prevent 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 spilled gasoline, and reinstall 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 OPERATING THE SNOW- THROWER. Keep face, hands, feet, and any other part of your body or clothing away from concealed, moving, or rotating parts. 11. BEFORE ADJUSTING, CLEANING, REPAIRING, AND INSPECTING THE SNOWTHROWER, AND BEFORE UN- CLOGGING 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 START- ING. USE A STICK TO REMOVE OB- STRUCTIONS. 12. Keep people and pets a safe dis- tance away from the snowthrower and area of operation. 13. Allow engine to warm up for about 2 minutes and machine to adjust to outdoor temperature before clearing snow. 14. Do not run engine indoors, except when starting engine. When starting engine indoors, open outside doors be- cause exhaust gasses are dangerous. 15. Operate the snowthrower only when there is good visibility or light. Always 2 maintain secure footing and balance and keep a firm grip on the handies, especially when operating in reverse. Walk; never run. 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 adjusted so auger housing clears ali rocks. 17. Do not make any adjustments while the engine 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 discharge angle. 19. STAY AWAY FROM DISCHARGE 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. 20. Clear snow from slopes by going up and down, never across the face. Use caution when changing directions. Use lower gear and rear wheel position when operating on slopes. Never clear snow from steep slopes. | 21. DO NOT USE SNOWTHROWER ON A ROOF. 22. Do not overload the snowthrower by clearing snow at too fast a rate. 23. If a solid object is hit or snow- thrower vibrates abnormally, shut en- gine off and wait for all moving parts to stop. Pull high tension wire off spark plug and check snowthrower immedi- ately for possible damage, an obstruc- tion, or loose parts. Vibration is gener- ally a sign of trouble. Repair any dam- age before restarting engine and oper- ating snowthrower again. A\ SAFETY INSTRUCTIONS 24. Do not touch engine while it is run- ning or soon after it is stopped be- cause 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 poten- tial hazard. | 25. Before leaving the operator's posi- tion (behind handles), rotate ignition key to OFF. Remove key from switch if snowthrower will be left unattended. 26. Never operate snowthrower at high transport speeds on slippery surfaces. Use care when backing. 27. Let snowthrower run for a few min- utes after clearing snow sO moving parts do not freeze. MAINTAINING SNOWTHROWER 28. Perform only those maintenance instructions 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 accidental starting. If major repairs are ever needed, contact your local Authorized TORO Service Dealer for assistance. 29. Keep snowthrower in safe operating condition by keeping nuts, bolts, and screws tight. Check engine mounting bolts frequently to assure they are tight. 30. Do not overspeed the engine by changing governor settings. Recom- mended maximum engine speed is 3500 rpm. To assure safety and accu- racy, check maximum engine speed (3500 rpm) with a tachometer. 31. Allow engine to cool before storing snowthrower in an enclosure such as a garage or storage shed, and make sure the snowthrower fuel tank is empty. NEVER STORE SNOWTHROWER IN HOUSE (LIVING AREA) OR BASEMENT BECAUSE GASOLINE AND FUMES ARE HIGHLY FLAMMABLE, EXPLOSIVE, AND DAN- - GEROUS IF INHALED. Do not store snowthrower near any open flame or where gasoline fumes may be ignited by a spark. 32. 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 memora- ble place. : 33.

BEFORE OPERATING FILL CRANKCASE WITH OIL (Fig. 8) The engine is shipped from the factory without oil in the crankcase. Therefore, before trying to start 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 8 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 as- sure an accurate oil level reading. 2. Clean area around dipstick to pre- vent foreign matter from entering filler hole when dipstick is removed. BEFORE OPERATING 3. Remove dipstick from crankcase (Fig. 8). Figure 8 1. Dipstick 3. Fuel tank cap 2. Filler hole 4. Slowly pour SAE 5W-30 or SAE 10 oil into the filler hole, using oil filler chart below. The engine uses any high-quality detergent oil having the American Petroleum Institute (API) “service classification” —SE or SF. Oil Fill Chart 828 Snowthrower 44 ounces of oil 1132 Snowthrower 48 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 REC- OMMENDS 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 RE- DUCING THE BUILDUP OF COMBUSTION CHAMBER DEPOSITS. LEADED GASO- LINE CAN BE USED IF UNLEADED IS NOT AVAILABLE. 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. DO NOT SMOKE while filling the fuel tank to prevent the possibility of an explosion. Al- ways fill fuel tank outside and wipe up any spilled gasoline before start- ing engine. Use a funnel or spout to prevent spilling gasoline, and fill fuel tank to about 1/2” (13 mm) from the top of the tank, not the filler neck. 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 sup- ply 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. IMPORTANT: NEVER USE METHANOL, GASOLINE CONTAINING METHANOL, GASOHOL CONTAINING MORE THAN 10% ETHANOL, PREMIUM GASOLINE, OR WHITE GAS BECAUSE ENGINE FUEL SYSTEM DAMAGE COULD RE- SULT. BEFORE OPERATING DO NOT USE FUEL ADDITIVES OTHER THAN THOSE MANUFACTURED FOR FUEL STABILIZATION DURING STOR- AGE (SUCH AS TORO'S PRESERVIT OR A SIMILAR PRODUCT). ADDITIVES SHOULD NOT BE USED TO TRY TO ENHANCE THE POWER OR PERFORM- ANCE OF MACHINE, 1. Clean area around the fuel tank cap (Fig. 8). Remove cap from fuel tank and fill tank to within 1/2” (13 mm) from the top with unleaded regular gasoline. Reinstall fuel tank cap. Fuel tank capacity is 4 quarts. CONTROLS Auger/Impeller Control (Fig. 9)—Con- trol has two positions: ENGAGE and DISENGAGE. To engage auger and im- peller, compress lever against right handle grip. To disengage, release lever. Traction Drive Control (Fig. 9)—To en- gage traction or activate power shift system, lever must be compressed against left handle grip. To stop trac- tion, release lever. Speed Shift Control (Fig. 9)—The con- trol has four speeds forward and two reverse and also controls power shift- ing of wheels. To select speeds, move shift control to desired position. Figure 9 1. Auger/impelier 3. Speed shift control control 2. Traction drive 4. lgnition switch control 5. Discharge chute control 10 Note: When shifting gears to change direction or shifting to the Power Shift position, traction drive control must be released. On-the-go shifting may be accomplished between any of the for- ward speeds without releasing traction drive control. Auger Lock-Up (Fig. 9)—When auger/ impeller control and traction drive con- trol are both compressed, the traction control locks the auger/impeller control down. Releasing the traction control releases the auger/impeller. Discharge Chute Control (Fig. 9)—Ro- tate discharge chute control clockwise to move discharge chute to the right and counterclockwise to move chute to the left. Ignition Switch (Fig. 9) —Switch has two position: ON and OFF. Rotate key to ON position before starting engine. To stop engine, rotate key to OFF. Throttle (Fig. 10)—Moving the throttle upward increases the engine speed. Choke (Fig. 10)—Choke is located on left side of engine. Push choke down to FULL choke position to start a cold engine. As engine warms up, move choke gradually to OFF. Primer (Fig. 10)—Press primer to pump small amount of gasoline into engine for improved cold weather start- ing. CONTROLS Deflector Handle (Fig. 12)—Deflector handle on top of discharge chute is used to control the height of the snow stream. Figure 10 Figure 12 1. Throttle 3. Primer 2" Choke 1.

Fuel shut-off valve 11 STARTING/STOPPING INSTRUCTIONS TO START ENGINE IMPORTANT: Check auger and impel- ler to assure that both parts are not frozen solid, but free to rotate. Also, make sure discharge chute is not ob- structed. 1. Move speed shift control to N (neu- tral) and throttle to FAST (Fig. 9). 2. Open fuel shut-off valve below fuel tank (Fig. 11). 3. Move choke to ON choke position (Fig. 10). 4. Rotate ignition key to ON (Fig. 9). 5. Depress primer (Fig. 10) five times. 6. Grasp recoil starter handle (Fig. 13) and pull it out slowly until positive en- gagement 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° F or below, addi- tional priming may be required. 7. After engine starts, immediately move choke (Fig. 10) to 3/4 position. As engine warms up, move choke to 1/2 position; then to OFF position. If engine falters, return choke to 1/2 po- sition. When engine warms sufficiently, move choke to OFF position. 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 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 pro- duces 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. 9). 2. Move speed shift control to N (neu- tral). 3. Move throttle to slow and rotate ig- nition key to OFF. OPERATING INSTRUCTIONS POWER SHIFT OPERATION Move wheels rearward to the Power Shift position 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 po- sition, move shift control fully forward to Power shift position and hold (Fig. 14). 3. Fully engage traction drive lever to move wheels into Power Shift position (Figs. 14 & 15). 12 Figure 14 Note: When power shifting it may be necessary to slightly raise handle to assist wheel movement. OPERATING INSTRUCTIONS Figure 15 Note: If wheels do not move in desired direction when power shifting, repeat procedure. Wheels must rotate in for- ward 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 engaged for self-propelled opera- tion. When axle pins are through outer axle holes (Fig. 16), snowthrower free wheels. By contrast, when both pins are installed through holes in wheel hub and inner hole of axle (Fig. 16), snowthrower will propel itself. Figure 16 1. Axle pin SNOWTHROWING TIPS 1. When snowthrower is not being used, close fuel shut-off vaive, have speed control in N (neutral) position, and key removed from the switch. 2. Remove snow as soon as possible after it falls. This produces best snow removal results. 3. When in the Power Shift position, push down on handies to increase traction. 4. To remove snow from crushed rock or gravel areas, adjust skids so bottom of auger housing clears the rock: refer to Adjusting Skids, page 13. 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 possible, and overlap each swath to assure complete snow removal. If wheels slip, shift into a lower gear to reduce 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 op- erate, stop the engine; then check all parts for freeze up. DO NOT USE EX- CESSIVE FORCE AND TRY TO OPERATE THE CONTROLS WHEN FROZEN. Free all controls and moving parts before operating. ADJUSTING SKIDS (Fig. 17) To use snowthrower on concrete or as- phalt surfaces, adjust skids using steps 1-2. However, use only step 3 when using snowthrower on gravel or crushed rock surfaces. 1. Move snowthrower to a level surface and move wheels rearward into the Power Shift position. 2. Next, loosen four flange bolts secur- ing both skids to auger side plates. Skids must slide up and down. 12 OPERATING INSTRUCTIONS 3. 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 bolts. 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. Figure 17 1. Flange bolts 2. Skid 4. Loosen four flange bolts 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 bolts. ADJUSTING SCRAPER If the amount of snow being picked up by the snowthrower begins to de- 14 crease, the scraper may need adjust- ment. 1. Move wheels rearward to the Power Shift position. 2. Loosen the (4) flange bolts securing both skids to the auger side plates (Fig. 17). 3. Next, loosen the (6) carriage bolts securing the scraper to the auger housing (Fig. 18). 5 — Figure 18 1. Scraper 2. Carriage bolt 4. Slide the scraper up and down until there is 1/8” between the bottom of the scraper and a level surface. 5. When the scraper is adjusted cor- rectly, tighten the (6) carriage bolts securely. 6. Readjust the skids so there is 1/8” between the bottom of the skids and a level surface. Tighten the (4) flange bolts securely. MAINTENANCE To prevent accidental starting of the engine while performing main- tenance, rotate ignition key to off and remove it from the switch. Next, pull wire off spark plug and make sure wire does not acciden- tally touch the plug. DRAINING GASOLINE 1. Close fuel shut-off valve located un- der engine (Fig. 19). Figure 19 1. Fuel shut-off valve 3. Fuel line 2. Hose clamp 2. Place a clean drain pan under shut- off valve. 3. Loosen hose clamps securing fuel line to valve and slide line off valve Since gasoline is highly flammable, drain it outdoors and make sure engine is cool to prevent a poten- tial fire hazard. Wipe up any gaso- line 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 pipe when handling gasoline. 4. Open valve allowing fuel to flow into drain pan. 5. Reinstall fuel line and secure with hose clamp. LUBRICATING SNOWTHROWER 1. Annually lubricate drive chain with chain lubricant (Fig. 20). Wipe up any excess oil. Figure 20 1. Drive chain CHANGING CRANKCASE OIL (Fig. 21) Initially, change oil after the first 2 hours of engine operation; thereafter, change oil after every 25 hours of en- gine operation or annually. If possible, run engine just before changing oil be- cause warm oil flows better and carries more contaminants than cold oil. Figure 21 1. Drain cap 15 MAINTENANCE 1. Pull wire off spark plug and make sure wire does not contact plug acci- dentally. 2. Clean area around oil drain cap. Next, slide oil drain pan below drain extension; then remove oil drain cap. 3. After all oil is drained, reinstall oil drain cap. 4. Position snowthrower on a level sur- face. Next, fill crankcase with oil: see Fill Crankcase With Qil, page 8. Wipe up any oil that may have spilled. REPLACING AUGER GEAR BOX OIL (Fig. 22) The auger gear box is filled with oil at the factory so regular maintenance is not required. However, if oil must be replaced in gear box: 1. Drain gasoline from fuel tank. Wipe up any spilled gas. 2. Position snowthrower on a level sur- face. 3. Clean area around pipe plug so dirt is removed. 4. Put a drain pan below front of auger gear box and remove pipe plug: refer to Check Auger Gear Box Oil, page 8. 5. Tip snowthrower forward and hold it up until ali oil drains from the gear box. 6. Carefully let snowthrower down to its normal position. Make sure it is on a level surface. Next, fill auger gear box with GL-5 or GL-6 SAE 85-95 EP transmission oil to the point of over- flow. 7. Install pipe plug in gear box. ADJUSTING AUGER/IMPELLER DRIVE BELT (Figs. 23-25) If auger/impeller belt slips, resulting in decreased snowthrowing performance, an adjustment is required. WHENEVER A NEW BELT IS INSTALLED, AN AD- JUSTMENT IS REQUIRED. 1. Remove (3) flange head capscrews securing belt cover to engine frame and slide belt cover up cables (Fig. 23). Figure 22 1. Pipe plug 16 Figure 23 1. Upper belt cover 3. Flange head 2. Cable cover capscrew 2. Check idler and brake adjustment. There should be a minimum clearance of 1/8” between tab on impeller idler warm and brake arm (Fig. 25). If there is less than 1/8” clearance, belt must be replaced. MAINTENANCE 3. Loosen upper jam nut securing auger/impeller cable to mounting bracket (Fig. 24). Figure 24 1. Auger/impeller 3. Mounting bracket cable 4. Jam nut 2. Traction cable 4. Rotate bottom jam nut upward to increase belt tension. Note: When adjusting cable, always rotate nut one turn at a time. 5. Tighten upper jam nut against bracket. IMPORTANT: Do not adjust the belt too tight because it may cause the auger/impeller to turn when the auger/impeller is in the disengaged position. If this occurs, readjust, loos- ening belt tension. Improper adjustment may cause in- jury if auger/impeller turns when disengaged. Figure 25 1. Impeller Idler arm 2. Brake arm 6. Recheck idler and brake adjustment: refer to step 2. 7. Reinstall belt cover. 8. Check tension of belt cover by op- erating the auger. If belt still slips, re- peat procedure. ADJUSTING TRACTION DRIVE BELT (Fig. 24) If traction belt slips during operation, an adjustment is required. Whenever “the belt is replaced, an adjustment is reguired. 1. Loosen upper jam nut securing trac- tion cable to mounting bracket. 2. Rotate bottom ¡am nut upward to increase belt tension. Note: When adjusting cable, always rotate nut one turn at a time. 3. Tighten upper jam nut against bracket. 4. Check tension of belt by operating machine. If belt still slips, repeat pro- cedure. IMPORTANT: Do not adjust the belt too tight because it may cause snowthrower to creep when traction lever is in disengaged position. If this occurs, readjust, loosening belt ten- sion. 17 MAINTENANCE REPLACING DRIVE BELTS (Fig. 26) If auger/impeller belt or traction belt become worn, glazed, stretched, oil- soaked, or otherwise defective, belt replacement is required. 1. Pull wire off spark plug and make sure it does not contact the plug acci- dentally. 2. Remove (3) flange head screws holding belt cover in place, and slide belt cover up cables. Cable must be free to slide in bracket when changing beit(s). 9. Reinstall belts by reversing proce- dure. Make sure tabs in half sheave are inserted into mounting grooves in auger/impeller pulley when reinstalling. Note: Make sure idler pulleys are aligned with belts when reinstalling idler pulley assembly. | 10. Readjust belts, refer to Adjusting Auger/Impeller Drive Belt or Adjusting Traction Drive Belt. e 1.

Remove capscrew and lockwasher securing half sheave to front of pulley assembly. 6. Slide auger/impeller pulley and belt off crankshaft and remove belt from impeller pulley. 7. If replacing traction belt, slide trac- tion pulley and belt off crankshaft and remove belt from transmission pulley. 8. On control cable which corresponds to belt being replaced, loosen jam nuts securing cable to bracket (Fig. 23). 18 Improper adjustment may cause in- jury if auger/impeller turns when disengaged. ADJUSTING DRIVE CHAIN (Figs. 27-30) The drive chain must be adjusted to maintain 1/8-3/8 of an inch deflection t mid span between transmission and axle sprocket. Check chain deflection after every 25 hours of operation. 1. Make sure wheels are positioned in rear position, move shift control into 2nd gear, and tip snowthrower up onto auger housing. | 1/8” - 3/8” DEFLECTION Figure 27 IMPORTANT: To adjust drive chain, the snowthrower must be tipped up on auger housing. However, before the snowthrower is tipped, drain all gasoline from fuel tank. MAINTENANCE 2. 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 speci- fied an adjustment is required. Figure 28 2. Transmission frame 1. Transmission 3. Loosen (4) flange head capscrews (2 each side) securing transmission frame to engine frame (Fig. 29). 4. Pivot rear of transmission frame until 1/8-3/8” chain deflection is attained, then, retighten flange head capscrews. Figure 29 1. Flange head capscrews IMPORTANT: Excessive chain tension may cause transmission damage. Note: If gear shift lever is not aligned with Power Shift slot in control panel (Fig. 30, inset), shift rod length must be adjusted as follows: A. Disconnect ball joint from transmission lever and loosen jam nut. B. Rotate ball joint up or down until gear shift lever is aligned with Power Shift slot. C. Reinstall ball joint to transmission lever and tighten jam nut. 5. Recheck chain deflection and lower snowthrower to normal position. e: № Figure 30 Shift rod 5. Locknut Ball joint 6.

IMPORTANT: Do not close needle valve too tight because valve and seat in carburetor will likely be damaged. 2. Rotate—open—needle valve 1-1/2 turns counterclockwise. 3. Idle Valve—Close idle valve finger- tight by gently rotating it clockwise. IMPORTANT: Do not close idle valve too tight because valve and seat in carburetor will likely be damaged. 4. Rotate—open—idle valve 1/4 turn to 3/4 of a turn counterclockwise. Engine must be running so final adjustment of the carburetor can be performed. To guard against possible personal injury, move auger drive and wheel drive con- trols to DISENGAGE, and remember to keep hands, feet, face, and other part of the body away from muffler, auger, discharge chute, and any moving part(s). Figure 31 1. Needle valve 3. Idle speed 2. Idle valve adjusting screw Note: The needle valve and idle valve settings are approximates; however, the settings will allow engine to be started so carburetor can be fine tu- ned—steps 5-11. 5. Start engine and let it warm up for approximately 2 to 3 minutes; then move throttle to FAST. 20 6. Rotate needle valve clockwise—in— until engine misses because of a lean gasoline mixture. Then rotate needle valve counterclockwise—out— until en- gine runs unevenly because of a rich gasoline mixture. Next, rotate needle valve clockwise, back to the midpoint between the rich and lean setting, so engine runs smoothly. 7. Move throttle control backward to idle speed. Next, rotate idle speed ad- justing screw until engine idles fast—1750 rpm. 8. Rotate idle valve clockwise—in—until engine begins to miss because of a lean mixture. Then rotate idle valve counterclockwise—out—until engine runs unevenly because of rich mixture. - Next, rotate idle valve clockwise, back to the mid-point between rich and lea settings. | 9. Again, rotate idle speed adjusting screw until engine idles at 1750 rpm. 10. Check carburetor adjustment by quickly moving throttle from idle speed to high speed. Engine should acceler- ate without hesitation or sputtering. If engine does not accelerate properly, adjust carburetor to a slightly richer mixture. 11. After carburetor is adjusted, shut engine off. MAINTENANCE REPLACING SPARK PLUG Use a Champion RCJ-8 or Autolite AR7N spark plug. 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 engine operation, install a new plug af- ter 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 wire off spark plug (Fig. 32) and remove plug from cylinder head. IMPORTANT: A cracked, fouled, or dirty spark plug must be replaced. Do not sand blast, scrape, or clean elec- trodes because grit may eventually release from the plug and fall into the cylinder. The result will likely be en- gine damage. Figure 32 1. Spark plug wire 3. Set air gap between electrodes of new spark plug at 0.030” (0.76 mm) (Fig. 33). Next, install spark plug in cylinder head. Tighten plug to 15 ft-lb (20.4 N-m). If torque wrench is not used, tighten plug firmly. 4. Push the wire onto spark plug. Figure 33 PREPARING SNOWTHROWER FOR STORAGE 1. Drain gasoline from fuel tank: refer to Draining Gasoline, page 15. Wipe up any gasoline that may have spilled. 2. Start the engine and let it run until it stops because there is no gasoline in the fuel system. 3. Remove spark plug from cylinder head. Next, pour two teaspoons of en- gine 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. 4. Lubricate the snowthrower: refer to Lubricating Snowthrower, page 15. 5. Change crankcase oil: see Changing Crankcase Oil, page 15. 6. Ciean the snowthrower. Touch up chipped surfaces with paint. Toro Re- Kote paint is available from an Author- ized TORO Service Dealer. Sand af- fected areas before painting, and use a rust preventative to prevent metal parts from rusting. 7. Tighten all screws and nuts. If any part is damaged, repair or replace it. 8. Store snowthrower in a clean, dry place, and cover it for protection. 9. The snowthrower may be stored in upright position. Be sure to drain gas and oil before tipping snowthrower up- right on auger housing. 21 IDENTIFICATION AND ORDERING MODEL AND SERIAL NUMBER To order replacement parts from an Authorized TORO Service Dealer, sup- The snowthrower has two identification ply the following information: numbers: a model number and a serial number.
