SAFETY NOTICE: Exposure to vibra
tions through prolonged use of gaso
line powered hand tools could cause
blood vessel or nerve damage in the
fingers, hands, and joints of people
prone to circulation disorders or abnor
mal swelling. Prolonged use in cold
weather has been linked to blood ves
sel damage in otherwise healthy
people, if symptoms occur such as
numbness, pain, loss of strength,
change in skin color or texture, or loss
of feeling in the fingers, hands, or
joints, discontinue the use of this tool
and seek medical attention. An
anti vibration system does not guaran
tee the avoidance of these problems.
Users who operate power tools on a
continual and regular basis must moni
tor closely their physicai condition and
the condition of this tool.
SPECIAL NOTICE; This unit is
equipped with a temperature limiting
muffler and spark arresting screen
which meets the requirements of Cali
fornia Codes 4442 and 4443. All U.S.
forest land and the states of California,
Idaho, Maine, Minnesota, New Jersey,
Oregon, and Washington require by
law that many internal combustion en
gines be equipped with a spark arrest
ing screen. If you operate in a locale
where such regulations exist, you are
legally responsible for maintaining the
operating condition of these parts. Fail
ure to do so is a violation of the law.

THROTTLE POSITION LEVER
The THROTTLE POSITION LEVER is de
signed to allow setting engine speed
during blower use only. To avoid caus
ing damage to the unit, DO NOT at
tempt to use the throttle position lever
during vacuum use.
PRIMER BULB
The PRIMER BULB removes air from
the carburetor and fuel lines and fills
them with fuel. This allows you to start
the engine with fewer pulls on the
starter rope. Activate primer bulb by
pressing it and allowing it to return to
its original position.
START LEVER
The START LEVER helps to supply fuel
to the engine to aid in starting. Activate
the starting system by moving the start
lever to the START position. DO NOT
squeeze the throttle trigger until the
engine has started and runs. After the
engine starts, allow the engine to
warm-up 10-15 seconds, then fully
squeeze the throttle trigger to deacti
vate the starting system (start lever re
turns to RUN position).
OPERATING TIPS
• While vacuuming or blowing debris,
hold the unit with the muffler side fac
ing away from your body and clothes
(see OPERATING POSITION below).
• To reduce the risk of hearing loss
associated with sound level(s), hear
ing protection is required,
• To reduce the risk of injury associated
with contacting rotating parts, stop the
engine before installing or removing
attachments. Do not operate without
guard(s) in place.
• Operate power equipment only at rea
sonable hours-not early in the morn
ing or iate at night when people might
be disturbed. Comply with times listed
in local ordinances. Usual recommen
dations are 9:00 a.m. to 5:00 p.m.,
Monday though Saturday,
• To reduce noise levels, limit the num
ber of pieces of equipment used at
any one time,
• To reduce noise levels, operate pow
er blowers at the lowest possible
throttle speed to do the job.
• Use rakes and brooms to loosen
debris before blowing.
• In dusty conditions, slightly dampen
surfaces or use a mister attachment
when water is available.
• Conserve water by using power blow
ers instead of hoses for many lawn
and garden applications, including
areas such as gutters, screens, patios,
grills, porches, and gardens.
• Watch out for children, pets, open
windows, or freshly washed cars.
Blow debris away safely,
• Use the full blower nozzle extension
so the air stream can work close to
the ground.
• After using blowers and other equip
ment, CLEAN UPl Dispose of debris
in trash receptacles.
OPERATING POSITION
BEFORE STARTING ENGINE
^WARNING: Be sure to read the
fuel information in the safety rules
before you begin. If you do not
understand the safety rules, do not
attempt to fuel your unit. Cali
1 -800-235-5878.
FUELING ENGINE
^WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on un
leaded gasoline. Before operation, gaso
line must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil.
Vife recommend Craftsman brand syn
thetic oil. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mix
ing 3.2 ounces of oil with 1 gallon of un
Page 10
leaded gasoline, included with this blow
er is a 3.2 ounce container of oil. Pour
the entire contents of this container into
1 gallon of gasoline to achieve the prop
er fuel mixture. DO NOT USE automotive
oil or boat oil. These oils will cause en
gine damage. When mixing fuel, follow
instructions printed on container. Once
oil is added to gasoline, shake container
momentarily to assure that the fuel is
thoroughly mixed. Always read and fol
low the safety rules relating to fuel be
fore fueling your unit.
IMPORTANT
Experience indicates that alcohol
blended fuels (called gasohol or using
ethanol or methanol) can attract mois
ture which ieads to separation and
formation of acids during storage.
Acidic gas can damage the fuel sys
tem of an engine while in storage.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season. Never use engine or
carburetor cleaner products in the fuel
tank or permanent damage may occur.
Fuel stabilizer is an acceptable alter
native in minimizing the formation of
fuel gum deposits during storage.
Craftsman brand oil is already blended
with fuel stabilizer. See the STORAGE
section for additional information.
HOW TO STOP YOUR ENGINE
• Release the throttle trigger.
• Push and hold the STOP switch in the
STOP position until the engine stops,
HOW TO START YOUR ENGINE
A WARNING: You MUST make sure
the tubes are secure before using the
unit.
• Fuel engine. Move at least 10 feet (3

• Hold the unit in the starting position
as shown. Make sure the blower end
Is directed away from people, ani
mals, glass, and solid objects.
^WARNING: When starting engine,
hold the unit as illustrated. Do not set
unit on any surface except a clean, hard
area when starting engine or while en
gine is running. Debris such as gravel,
sand, dust, grass, etc. could be picked
up by the air intake and thrown out
through the discharge opening, damag
ing the unit or property, or causing seri
ous injury to bystanders or the operator.
STARTING A COLD ENGINE (or
warm engine after running out of fuel)

starter rope handle sharply or
briskly. Pull starter rope handle 5
times with a controlled and steady
motion (no more than 3 times
above 90°F). If engine starts and
runs prior to 5 pulls, allow engine to

STARTING A WARM ENGINE
1. Squeeze and hold the throttfe trigger.
2, Pull starter rope handle with a con
trolled and steady motion while
squeezing throttle trigger until en
gine starts and runs.
NOTE: Normally, the warm starting
prooedure can be used within 5-10
minutes after the unit is turned off. If
the unit sits for more than 10 minutes
without being used, it will be necessary
to start the unit by following the steps
under STARTING A COLD ENGINE or fol
lowing the starting instruction steps
shown on the unit.
STARTING A FLOODED ENGINE
Flooded engines can be started by mov
ing the start lever to the RUN position
and fully squeezing the throttle trigger.
Pull the starter handle repeatedly while
squeezing throttle trigger until engine
starts and runs. This could require pull
ing the starter handle many times, de
