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 andbrooms to loosen debris be-
fore blowing.
S In dusty conditions, slightly dampen sur-
faces or use a mister attachment when water 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 forchildren, pets, open windows,
or freshly washed cars. Blow debris away
safely.
S Use the full blower nozzle extension so the

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, donot attemptto 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 thesafety rules beforefueling your unit.
IMPORTANT
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) canattract moisture which leads to
separation andformation of acids during storage. Acidic gas can damage the fuel system
of anengine while in storage. To avoid engine
problems, empty the fuel system before storage for 30days or longer. Drain the gas tank,
start the engine andlet it run untilthe fuellines
and carburetor areempty. Use fresh fuelnext
season. Never use engine or carburetor
cleaner productsin thefuel tank or permanent
damage may occur.
