Safety Rules & Information
Operating Safety
Congratulations on purchasing a superior-quality piece of lawn
and garden equipment. Our products are designed and manu-
factured to meet or exceed all industry standards for safety.
Power equipment is only as safe as the operator. If it is mis-
used, 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
DO NOT ALLOW CHILDREN TO OPERATE THIS UNIT!
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.
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.

Safety Rules & 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 prop-
erty 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 run-
ning! 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 perfor-
mance of your unit. Be sure to perform the maintenance
procedures listed in this manual, especially periodically
testing the safety system.

help start a cold engine. Normally, pressing the primer
button twice will provide enough fuel to start a cold
engine.
Models with Manual Chute Rotator: Turning the crank
rotates the discharge chute to desired position.
Remote/Regular Deflector Control
Regular (Knob) Chute Deflector: Locks chute deflector in
desired position. Tilting the chute deflector UP provides
a higher stream and greater distance, while tilting the
deflector DOWN provides a lower stream and less dis-
tance.
Throttle Lever
Controls engine speed. Move toward the hare icon for
faster engine speed, move toward the turtle icon for
slower engine speed. Move the throttle all the way to
STOP to stop the engine. Set throttle to FULL/FAST
(hare icon) for operation.
Remote Chute Deflector: Twist the knob to unlock the
chute deflector. Pull or push the knob to change the
deflector angle. UP provides a higher stream and
greater distance, while tilting the deflector DOWN pro-
vides a lower stream and less distance.

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 machine. Do not operate the machine without the
clean-out tool properly stored on the machine.
3. Check the engine oil level. See your engine owner’s
manual for procedure and specifications.
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.
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 expan-
sion. See your engine owner’s manual for fuel recom-
mendations.
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 (B, Figure 4), and auger con-
trol (C) for proper operation. If adjustment is required,
see the service section for procedures.
1. Stop the engine. Remove the key.
2. Wait 10 seconds to be sure the auger/impeller
blades have stopped rotating.

Storage
AFTER EACH USE
STORAGE
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.
• Disengage the PTO, set the parking brake, and
remove the key.
• 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 struc-
ture - see Warning).
2. Stop the engine by moving the throttle lever (See
Figure 1) down, or by pulling out the engine key.
3. Brush snow and ice from the snowthrower. Be sure to
clear engine and snowthrower controls, discharge
chute, worm and chute rod gears, clutch cable areas,
and anywhere else snow has accumulated.
Before starting the unit after it has been stored:
4. Always remove the engine key and store in a safe
place to prevent unauthorized use.
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures
found in the engine owner’s manual.
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.
• Allow the engine to warm up for several minutes
before use.
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.

A. Adjustment Nut
B. Jam Nut
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.)
B
The shear pins are located on the auger shaft as shown
in Figure 26. To replace the shear pins, tap out the bro-
ken pin with a pin punch, and install a new shear pin and
cotter pin. Spread the legs of the new cotter pin fully. Do
NOT replace shear pins with anything other than the
correct grade replacement shear pin. (Use of bolts,
screws or a harder shear pin will lead to damaged equip-
ment.)

Specifications
NOTE: Specifications are correct at time of printing and are subject to change without notice.
* 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.
