wise 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 condition
of this tool.

OPERATING TIPS
SWhile vacuuming or blowing debris, hold
the unit with the muffler side facing away
from your body and clothes (see OPERAT-
ING POSITION).
STo reduce the risk of hearing loss
associated with sound level(s), hearing
protection is required.
STo 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.
SOperate 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.
STo reduce noise levels, limit the number of
pieces of equipment used at any one time.
STo reduce noise levels, operate power
blowers at the lowest possible throttle
speed to do the job.
SUse rakes and brooms to loosen debris be-
fore blowing.
SIn dusty conditions, slightly dampen sur-
faces or use a mister attachment when wa-
ter is available.
SConserve 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.
SWatch out for children, pets, open windows,
or freshly washed cars. Blow debris away
safely.
SUse the full blower nozzle extension so the
air stream can work close to the ground.
SAfter using blowers and other equipment,
CLEAN UP! Dispose of debris in trash re-
ceptacles.
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. Contact
an authorized service dealer.
FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
This engine is certified to operate on
unleaded petrol. Before operation, petrol
must be mixed with a good quality 2-cycle
air-cooled engine oil. We recommend
McCulloch brand oil mixed at a ratio of 40:1
(2.5%). A 40:1 ratio is obtained by mixing 5
liters of unleaded petrol with 0,125 liter of oil.
When mixing fuel, follow the instructions
printed on the container. Always read and
follow the safety rules before fueling your unit.
IMPORTANT
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 stor-
age. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine
problems, empty the fuel system before stor-
age for 30 days or longer. Drain the gas tank,
start the engine and let it run untilthe 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.
HOW TO STOP YOUR ENGINE
SRelease the throttle trigger.
SPush and hold the STOP switch in the
STOP position until the engine stops.
BEFORE STARTING THE ENGINE
WARNING: YouMUSTmakesurethe
tubes are secure before using the unit.
DFuel engine. Move at least 3 meters away
from the fueling site.
DHold the unit in the starting position as
shown. Make sure the blower end is di-
rected away from people, animals, glass,
and solid objects.

Note 1: Noise emissions in the environment measured as sound power (LWA) in conformity
with EC directive 2000/14/EC. Reported sound power level for the machine has been mea-
sured with the original cutting attachment that gives the highest level. The difference between
guaranteed and measured sound power is that the guaranteed sound power also includes
dispersion in the measurement result and the variations between different machines of the
same model according to Directive 2000/14/EC.
Note 2: Reported data for equivalent sound pressure level for the machine has a typical
statistical dispersion (standard deviation) of 1 dB(A).
Note 3: Reported data for equivalent vibration level has a typical statistical dispersion (stan-
dard deviation) of 1 m/s2.
