WARNING signals a hazard that may cause serious injury or death if the recommended precautions are not followed. CAUTION signals a hazard that may cause minor or moderate injury if the recommended precautions are not followed. Two other words are also used to highlight information. “Important” calls attention to special mechanical information and “Note” emphasizes general information worthy of special attention. Before Operating 1.
A. Use an approved gasoline container. B. C. 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. 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 12.
Maintaining Snowthrower 26. 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. 27. Keep snowthrower in safe operating condition by keeping nuts, bolts, and screws tight.
BEFORE OPERATING 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. CAUTION: IMPROPER USE MAY RESULT IN LOSS OF FINGERS, HANDS OR FEET. HIGH SPEED IMPELLER WITHIN 2 INCHES OF OPENING OPERATOR'S POSITION LOW SPEED AUGER HAS MOVING PINCH POINT, CLOSE TO OPENING.
Safety Decals and Instructions Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Loose Parts DESCRIPTION QTY.
Assembly Note: Determine left and right sides of snowthrower by standing in the normal operating position. Install Handle 1. 2. 3. Remove tie straps securing control rods to handle. 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. Position left handle against side of unit, make sure traction rod goes through loop in lower traction rod (Fig.
Install Auger/Impeller Drive Control Linkage 1. 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. Compress auger/impeller control lever slowly toward handgrip.
Before Starting ENGINES WHICH ARE CERTIFIED TO COMPLY WITH CALIFORNIA AND U.S. EPA EMISSION REGULATIONS FOR ULGE ENGINES: Are certified to operate on regular unleaded gasoline. Include the following emission control system(s): EM, TWC (if so equipped); Do not include any user adjustable features – therefore no other adjustments are needed. Fill Crankcase With Oil The engine is shipped from the factory without oil in the crankcase. Before starting the engine, oil must be added to the crankcase.
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.
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. 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. position. If engine falters, return choke to 1/2 position.
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. 6. POTENTIAL HAZARD • When snowthrower is in operation, impeller and auger can be rotating. 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.
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) until the skids can be slid up and down easily. Maintenance POTENTIAL HAZARD • If you leave the wire on the spark plug, someone could start the engine. WHAT CAN HAPPEN 4. Support the auger blades off the ground so that both the scraper and the auger blades (Fig.
4. Open valve by rotating valve to the left. This allows fuel to flow into drain pan. 5. Reinstall fuel line and secure with hose clamp. Lubricating Snowthrower 3. Clean area around oil drain plug. Next, slide oil drain pan below drain extension; then remove oil drain plug (Fig. 22). 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 Oil, page 10.
2. 3. Check adjustment per steps 4–6 of Install Auger/Impeller Drive Control Linkage, page 9. Make adjustments if required. Check tension of belt by operating the auger/impeller. If belt still slips, replace the belt. USE ONLY GENUINE TORO REPLACEMENT PARTS. Replacing Auger/Impeller Drive Belt When auger/impeller drive belt (Fig. 24) becomes worn, stretched, oil–soaked or otherwise damaged, belt replacement is required. 1. 2. 3. 4. 2. Drain gasoline from fuel tank.
Note: If auger/impeller drive belt is replaced with a new belt, adjust auger/impeller drive linkage. Refer to steps 4–6 of Install Auger/Impeller Drive Control Linkage, page 9. 5. With drive assembly 1/8” from contacting roll pin, tighten flange nuts securing speed selector plate. 6. Shift speed selector to R (REVERSE) and back to third to check adjustment. If space between roll pin and drive assembly is more than #/16 of an inch (4.8 mm), repeat steps 2–4. 7. Reassemble bottom cover with (4) screws.
• 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.
