gon, and Washington require by law that
many internal combustion engines be
equipped witha spark arresting screen. If you
operatein alocalewhere such regulations ex-
ist, you are legally responsible for maintaining
the operating condition of these parts. Failure
to do so is a violation of the law. Refer to the
MAINTENANCE section for information on

SAFETY NOTICE: Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of
people prone to circulation disorders or ab-
normal swelling. Prolonged use in cold
weather has beenlinked to blood vesseldam-
age 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 antivibration system
does not guarantee the avoidance of these
problems. Users who operate power tools on
a continual and regular basis must monitor
closely their physical condition and the condi-
tion of this tool.

CHOKE LEVER
ON/STOP SWITCH
The ON/STOP SWITCH is used to stop the en-
gine. To stop the engine, move the switch to the
STOP position.
The CHOKE helps to supply fuel to the engine
to aid in cold starting. Activate the choke by
moving the choke lever to the CLOSE position.
Once engine starts, move choke lever to the
OPEN position.
PRIMER BUTTON
The PRIMER BUTTON 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 button
by pressing it and allowing it to return to its origi-
nal position.
THROTTLE ADJUSTER
The THROTTLE ADJUSTER can be used to
select the speed of air flow. To avoid holding
your finger on the throttle trigger all the time,
the required speed can be set with the throttle
adjuster. Full throttle is obtained by squeez-
ing the throttle trigger and moving the throttle
adjuster clockwise until it stops.
S Operate power equipment only at reasonable
hours--not early in the morning or late at night
when people might be disturbed. Comply with
times listed in local ordinances. Usual recom-
mendations are 9:00 a.m. to 5:00 p.m.,
Monday though Saturday.
OPERATING POSITION
otection
S To reduce noise levels, limit the number of
pieces of equipment used at any one time.
S To reduce noise levels, operate power
blowers at the lowest possible throttle
speed to do the job.
S Use rakes and brooms to loosen debris be-
fore blowing.
S In dusty conditions, slightly dampen sur-
faces or use a mister attachment when wa-
ter is available.
S Conserve water by using power blowers
instead of hoses for many lawn and garden
applications, including areas such as gutters,
screens, patios, grills, porches, and gardens.
S Watch out for children, pets, open windows,
or freshly washed cars. Blow debris away
safely.
OPERATING TIPS
S To reduce the risk of hearing loss
associated with sound level(s), hearing
protection is required.
S To reduce the risk of injury associated with
contacting rotating parts, stop the engine be-
fore installing or removing attachments. Do
not operate without guard(s) in place.

S Use the full blower nozzle extension so the
air stream can work close to the ground.
S After using blowers and other equipment,
CLEAN UP! Dispose of debris in trash re-
ceptacles.

surface except a clean, hard area when starting
engine or while engine is running. Debris such
as gravel, sand, dust, grass, etc. could be

FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil
designed to be mixed at a ratio of 50:1. A 50:1
ratio is obtained by mixing 2.6 ounces of oil
with 1 gallon of unleaded gasoline. DO NOT
USE automotive oil or boat oil. These oils will
cause engine damage. When mixing fuel,
follow the instructions printed on container.
Once oil is added to gasoline, shake
container momentarily to assure that the fuel
is thoroughly mixed. Always read and follow
the safety rules relating to fuel before fueling
your unit.
WARNING: Avoid contact with the
muffler. A hot muffler can cause serious
burns.
STARTING A COLD ENGINE (or warm
engine that has run out of fuel)
1. Move ON/STOP switch to the ON posi-
tion.
2. Move the choke lever to the CLOSE posi-
tion.
3. Slowly press the primer button (located
under the carburetor) 6 times.

Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to
separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. Toavoid
engine problems, empty the fuel system
before storage for 30 days or longer. Drain the
gas tank, start theengine 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.
4. Squeeze throttle trigger and turn throttle
adjuster clockwise until it stops.

WARNING: Avoid touching muffler
unless engine and muffler are cold. A hot
muffler can cause serious burns.
As the unit is used, carbon deposits build up
on the muffler and spark arresting screen,
and must be removed to avoid creating a fire
hazard or affecting engine performance.
Replace the spark arresting screen every 50
hours of operation or if any damage or breaks in
the screen are noted.
CHECK FOR DAMAGED OR WORN

paper air filter with water. Do not use pressur-
ized air to clean or dry the air filter. Always re-
place a damaged air filter.
