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.
another responsible adult watch them.
Children
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.
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

Safety Rules and Information
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.

Operation
GENERAL OPERATION
WARNING
This unit is a “two-stage” snowthrower.
CHECKS BEFORE EACH START-UP
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.
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.
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.
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.
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:
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
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.
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.
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.
9. Check the chute deflector (
Figure 1) for
proper operation. The deflector should pivot freely
up and down when knob is loosened.
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).
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
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

CLEARING A CLOGGED
DISCHARGE CHUTE
Hand contact with the rotating auger/impeller inside
the discharge chute is the most common cause of
injury associated with snowthrowers. DO NOT use
your hand to clean out the discharge chute. To clear
the chute:
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.
1. Stop the engine. Remove the key
Handle gasoline carefully. It is highly
flammable and careless use could result in
serious fire damage to your person or property.
2. Wait 10 seconds to be sure the auger/impeller
blades have stopped rotating.
Drain fuel into an approved container outdoors
away from open flame or sparks.
3. Use the clean-out tool to remove clogs. DO NOT
use your hands.
STORAGE
AFTER EACH USE
Normal use of the snowthrower may result in a build-
up 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.
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.
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.
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:
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.
• 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).
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).
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance
items.
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.
• Perform all recommended checks and procedures
found in the engine owner’s manual.
• Allow the engine to warm up for several minutes
before use.
4. Always remove the engine key and store in a safe
place to prevent unauthorized use.
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.
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.

Do not go near the discharge chute or auger
when the engine is running. Do not run the
engine with any cover or guard removed.
A
Under most circumstances, if the auger strikes an
object which could cause damage to the unit, the
shear pin will break. (This protects the gear box and
other parts from damage.)

Specifications

* 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.
