except  
for  
carburetor  
D Keep outside surfaces free of oil and fuel.  
D Never start or run engine inside a closed  
room or building. Breathing exhaust fumes  
can kill.  
D Mufflers fitted with catalytic converters get  
very hot during use and remain so for some  
time after stopping. This also applies at idle  
speed. Contact can result in burns to the skin.  
Remember the risk of fire!  
D To avoid static electricity shock, do not wear  
rubber gloves or any other insulated gloves  
while operating unit.  
D Do not set unit on any surface except a clean,  
hard area while engine is running. Debris  
such as gravel, sand, dust, grass, etc. could  
be picked up by the air intake and thrown out  
through discharge opening, damaging unit,  
property, or causing serious injury to  
bystanders or operator.  
D Avoid dangerous environments. Do not use in  
unventilated areas or where explosive vapors  
or carbon monoxide build up could be  
present.  
D Do not overreach or use from unstable  
surfaces such as ladders, trees, steep  
slopes, rooftops, etc. Keep firm footing and  
balance at all times.  
D Never place objects inside the blower tube;  
always direct the blowing debris away from  
people, animals, glass, and solid objects such  
as trees, automobiles, walls, etc. The force of  
air can cause rocks, dirt, or sticks to be  
thrown or to ricochet which can hurt people or  
animals, break glass, or cause other damage.  
D Never run unit without the proper equipment  
attached. Always install blower tube.  
D Use  
only  
recommended  
McCulloch  
replacement parts; use of any other parts  
may void your warranty and cause damage to  
your unit.  
D Empty fuel tank before storing the unit. Use  
up fuel left in carburetor by starting engine and  
letting it run until it stops.  
D Do not use any accessory or attachment  
other than those recommended by  
manufacturer for use with your unit.  
D Do not store the unit or fuel in a closed area  
where fuel vapors can reach sparks or an  
open flame from hot water heaters, electric  
motors or switches, furnaces, etc.  
D Store in a dry area out of reach of children.  
D Secure the machine during transport.  
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 peo-  
ple prone to circulation disorders or abnormal  
swelling. Prolonged use in cold weather has  
been linked to blood vessel damage in other-  
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.  
D Check air intake opening and blower tube  
frequently, always with engine stopped and  
spark plug disconnected. Keep vents and  
discharge tube free of debris which can  
accumulate and restrict proper air flow.

OPERATION  
This engine is certified to operate on  
OPERATING POSITION  
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 beforefueling your unit.  
OPERATING  
POSITION  
Hearing Protection  
Eye Protection  
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 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.  
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 tube. Do not oper-  
ate without guard(s) in place.  
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.  
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.  
HOW TO STOP YOUR ENGINE  
D To stop the engine, move the throttle lever  
to the STOP  
position and hold until en-  
gine stops running.  
BEFORE STARTING THE ENGINE

D Hold the unit in the starting position as  
shown. Make sure the blower end is di-  
rected away from people, animals, glass,  
and solid objects.  
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 Watchout for children, pets, openwindows,  
or freshly washed cars. Blow debris away  
safely.  
STARTING  
POSITION
