Safety Rules & Information
Operating Safety
Congratulations on purchasing a superior-quality piece of lawn and garden equipment. Our products are designed and manufactured to meet or exceed all industry standards for safety.
Power equipment is only as safe as the operator. If it is misused, or not properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you.
Use common sense, and think through what you are doing. If you are not sure that the task you are about to perform can be safely done with the equipment you have chosen, ask a professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information you need to be aware of BEFORE you operate your unit as well as DURING operation.
Safe operating techniques, an explanation of the product’s features and controls, and maintenance information is included to help you get the most out of your equipment investment.
Be sure to completely read the Safety Rules and Information found on the following pages. Also completely read the Operation section.
Children
Tragic accidents can occur with children. Do not allow them anywhere near the area of operation. Children are often attracted to the unit and snowthrowing activity. Never assume that children will remain where you last saw them. If there is a risk that children may enter the area where you are operating the unit, have
another responsible adult watch them. DO NOT ALLOW CHILDREN TO OPERATE THIS
UNIT! This encourages them to come near the unit in the future while it is running, and they could be seriously hurt. They may then approach the unit when you are not expecting it, and you may run over them.
5
Safety
Moving Parts
This equipment has many moving parts that can injure you or someone else. However, if you are standing in the operator’s position, and follow all the rules in this book, the unit is safe to operate.
The auger and impeller have spinning parts that can amputate hands and feet. Do not allow anyone near the equipment while it is running! DO NOT clear the discharge chute by hand. If the chute becomes plugged, stop the engine, wait for all moving parts to stop, and clear the blockage with a clean-out tool or piece of wood.
To help you, the operator, use this equipment safely, it is equipped with an operator-present safety system. Do NOT attempt to alter or bypass the system. See your dealer immediately if the system does not pass all the safety interlock system tests found in this manual.
Thrown Objects
This unit has a spinning auger and impeller. They pick up and throw snow and ice. Thrown debris could seriously injure a bystander. ALWAYS direct the discharge chute away from bystanders and property that could be damaged by frying debris. Be sure to clean up the area to be cleared BEFORE you start.
Do not allow anyone in the area while the unit is running! If someone does enter the area, shut the unit off immediately until they leave.
Fuel and Maintenance
Gasoline is extremely flammable. Its vapors are also extremely flammable and can travel to distant ignition sources. Gasoline must only be used as a fuel, not as a solvent or cleaner. It should never be stored any place where its vapors can build up or travel to an ignition source like a pilot light. Fuel belongs in an approved, plastic, sealed gas can, or in the snowthrower fuel tank with the cap securely closed. Spilled fuel needs to be cleaned up immediately.
Proper maintenance is critical to the safety and performance of your unit. Be sure to perform the maintenance procedures listed in this manual, especially periodically testing the safety system.

GENERAL OPERATION
CHECKS BEFORE EACH START-UP
1. Make sure all safety guards are in place and all nuts, bolts and clips are secure.
2. Check to make sure that the clean-out is attached to the auger housing. Do not operate the machine without the clean-out tool properly stored on the auger housing.
3. Check the engine oil level. See your engine owner’s manual for procedure and specifications.
4. Check to make sure spark plug wire is attached and spark plug is tightened securely. If necessary, torque spark plug to 15 ft. lbs.
5. Check the fuel supply. Fill the tank no closer than 1/4 to 1/2 inch of top of tank to provide space for expansion. See your engine owner’s manual for fuel recommendations.
6. Check the scraper bar to make sure it is set at the desired height. Adjust the skid shoes if necessary.
7. Check the drive control ( ,Figure 1), and auger
control ( ,Figure 1) for proper operation. If adjustment is required, see the service section for
procedures.
8. Check the chute direction control ( ,Figure 1) for proper operation. The discharge chute should
rotate freely in both directions. See the service section for adjustment procedures and troubleshooting.
9. Check the chute deflector ( Figure 1) for proper operation. The deflector should pivot freely
up and down when knob is loosened.
10.Position the chute at the desired starting direction and set the deflector at the desired angle.
11.Check the speed selector ( ,Figure 1) for smooth operation. The control must move freely
into each speed position gate and remain in position when released. If the speed selector does not move freely into all forward and reverse speed positions, contact your local authorized dealer for assistance.
WARNING
This unit is a “two-stage” snowthrower. The first stage is the auger, which feeds the
snow back into the impeller housing. The second stage is the impeller, which throws the snow out the discharge chute. If bodily contact is made with the auger or impeller when they are rotating, severe personal injury will occur.
To avoid injury, keep others and yourself away from the auger and the discharge chute whenever the engine is running. Read and follow all of the safety rules and warnings in this manual.
DANGER
Do not clean out discharge chute with hands. Contact with moving parts inside chute will cause serious injury. Use clean out tool provided with machine. Use the following procedure to remove objects or clear the chute:
1. Stop the engine. Remove the key
2. Wait 10 seconds to be sure the auger/impeller blades have stopped rotating.
3. Always use the clean-out tool. DO NOT use your hands.
WARNING
For your safety, operation on slopes should be in an up and down direction only. If it becomes necessary to move across the face of a slope, use caution and do not blow snow. Be very careful when changing direction on a slope.
Proper winter footwear is recommended for the operator to help prevent slipping. Never attempt to clean snow from excessively steep slopes. The maximum slope for any operation is 17.7% (10º).
WARNING
Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is hot or running. Always move outdoors to fill the tank. Keep snowthrower and gasoline away from open flame or spark.

Operation
AFTER EACH USE
Normal use of the snowthrower may result in a build­up of packed snow in and around the starter cord housing and around engine controls. Heat from the engine will usually prevent the snow from freezing solid while the unit is running, but after the engine is shut down, some snow may continue melting from engine heat, and later freeze around some moving parts as the unit cools.
After each period of use, follow these steps to prevent freeze-up caused by ice formation in and around the engine controls and external parts.
1. Before shutting off the engine, pull the starter rope out 2 - 3 times, and allow it to rewind slowly. This will help clear packed snow from the starter cord area. Allow the engine to run for several minutes.
2. Stop the engine by pushing the stop switch (C, Figure 2) to the off position then pull out the engine key (D, Figure 2).
3. Brush snow and ice from the snowthrower. Be sure to clear engine and snowthrower controls, discharge chute, and chute rod gears, clutch cable areas, and anywhere else snow has accumulated.
4. Always remove the engine key and store in a safe place to prevent unauthorized use.
5. If the snowthrower is kept in a cold shelter, fill the fuel tank to prevent condensation. Do not store near sparks or flame.
Note: The Engine Owner’s Manual contains further information on preventing ice formation and freeze-up.
WARNING
Never store the unit (with fuel) in an enclosed, poorly ventilated structure. Fuel vapors can travel to an ignition source (such as a furnace, water heater, etc.) and cause an explosion.
Fuel vapor is also toxic to humans and animals.
WARNING
Never store the unit, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion.
Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to your person or property.
Drain fuel into an approved container outdoors away from open flame or sparks.
STORAGE
Before you store your unit for the off-season, read the Maintenance and Storage instructions in the Safety Rules section, then perform the following steps:
• Perform engine maintenance and storage measures listed in the engine owner’s manual. This includes draining the fuel system, or adding stabilizer to the fuel (do not store a fueled unit in an enclosed structure - see warning).
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures found in the engine owner’s manual.
• Allow the engine to warm up for several minutes before use.

LUBRICATION
Remove wheels and grease axles once each year. Apply 5W-30 synthetic motor oil sparingly to the
friction disk drive hex shaft (A, Figure 15). Apply medium weight (10W) oil to points shown (See
Figures 14-17). Generally, all moving metal parts should be oiled
where contact is made with other parts. Keep oil and grease off belts, pulley grooves, drive disc, and friction disc.
LUBRICATION NOTES:
Grease locations indicated by grease gun symbol. Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed.
Oil locations indicated by oil can symbol. Do not allow oil to drip onto traction drive or friction disc.
IMPORTANT NOTE
It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break.
To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly.

* Power Ratings
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of
Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance
has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived
at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is
affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the
wide array of products on which engines are placed and the variety of environmental issues applicable to
operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of
power equipment (actual "on-site" or net power). This difference is due to a variety of factors including, but not
limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations,
ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to
manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this
Series engine.
