General Information
This symbol means WARNING or PERSONAL SAFETY INSTRUC- TION - read the instruction because if has to do with your safety. Failure to comply with the instruction may result in personal injury or even death.
This manual is intended as a service and repair manual only. The safety instructions provided herein are for troubleshooting, service, and repair of the Toro SnowMaster ® and SnowMax ® snowthrowers. The SnowMaster operator's manuals contain safety information and operating tips for safe operating practices. Operator's manuals are available through your Toro parts source or:

Think Safety First
Avoid unexpected starting of engine... Always turn off the engine and disconnect the spark plug wire(s) before cleaning, adjusting, or repair.
Avoid lacerations and amputations... Stay clear of all moving parts whenever the engine is running. Treat all normally moving parts as if they were moving whenever the engine is running or has the potential to start.
Avoid burns... Do not touch the engine, muffler, or other components which may increase in temperature during operation, while the unit is running or shortly after it has been running.
Avoid fires and explosions... Avoid spilling fuel and never smoke while working with any type of fuel or lubricant. Wipe up any spilled fuel or oil immediately. Never remove the fuel cap or add fuel when the engine is running. Always use approved, labeled containers for storing or transporting fuel and lubricants.
Avoid asphyxiation... Never operate an engine in a confined area without proper ventilation.
Avoid injury from batteries... Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes, and clothing. Battery gases can explode. Keep cigarettes, sparks, and flames away from the battery.
Avoid injury due to inferior parts... Use only original equipment parts to ensure that important safety criteria are met.
Avoid injury to bystanders... Always clear the area of bystanders before starting or testing powered equipment.
Avoid injury due to projectiles... Always clear the area of sticks, rocks, or any other debris that could be picked up and thrown by the powered equipment.
Avoid modifications... Never alter or modify any part unless it is a factory approved procedure.
Avoid unsafe operation... Always test the safety interlock system after making adjustments or repairs on the machine. Refer to the Electrical section in this manual for more information.

Standard Torque Values (Metric Fasteners)

INCH/METRIC NOTE: Reduce torque values listed in the table above by 25% for lubricated fasteners. Lubricated fasteners are defined as threads coated with a lubricant such as oil, graphite, or thread sealant such as Loctite
INCH/METRIC NOTE: Torque values may have to be reduced when installing fasteners into threaded aluminum or brass. The specific torque value should be determined based on the fastener size, the aluminum or base material strength, length of thread engagement, etc.
INCH/METRIC NOTE: The nominal torque values listed above for Grade 5 and 8 fasteners are based on 75% of the minimum proof load specified in SAE J429. The tolerance is approximately ± 10% of the nominal torque value. Thin height nuts include jam nuts.
METRIC NOTE: The nominal torque values listed above are based on 75% of the minimum proof load specified in SAE J1199. The tolerance is approximately ± 10% of the nominal torque value. Thin height nuts include jam nuts.

Storage
Storing the Snowthrower

• Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If you store the machine in an area with an open flame, the gasoline fumes may ignite and cause an explosion.
• Do not store the machine in a house (living area), basement, or any other area where ignition sources may be present, such as hot water and space heaters, clothes dryers, furnaces, and other like appliances.
• Do not tip the machine backward with fuel in the fuel tank; otherwise, fuel may leak out of the machine.

1. On the last refueling of the season, add fuel stabilizer to fresh fuel as directed by the engine manufacturer.
2. Run the engine for 10 minutes to distribute the conditioned fuel through the fuel system.
3. Stop the engine, allow it to cool, and siphon the fuel tank or run the engine until it stops.
4. Start the engine and run it until it stops.
5. Choke or prime the engine, start it a third time, and run the engine until it will not start.
6. Drain the fuel in the carburetor through the carburetor drain bolt into an approved gasoline container.
7. Dispose of unused fuel properly. Recycle it according to local codes, or use it in your automobile.
8. While the engine is still warm, change the engine oil.
9. Remove the spark plug.
10. Squirt 2 teaspoons of oil into the spark plug hole.
11. Install the spark plug by hand and then torque it to 27–30 N-m (20–22 ft-lb).
12. With the ignition key in the Off position, pull the recoil starter slowly to distribute the oil on the inside of the cylinder.
13. Clean the machine.
14. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting.
15. Tighten any loose fasteners. Repair or replace any damaged parts.

16. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure.
