blowers at the lowest possible throttle
speed to do the job.
OPERATING TIPS
WARNING: While vacuuming or
blowing debris, hold the unit with the muffler
side facing away from your body and clothes
(see OPERATING POSITION).
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 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.
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.

OPERATING POSITION
IMPORTANT
Use of alcohol blended fuels (called gasohol or
using ethanol or methanol) can cause major
engine performance and durability problems.
WARNING: While vacuuming or
blowing debris, hold the unit with the muffler
side facing away from your body and clothes
(see following illustration).
WARNING: Alternative fuels (not gas-
oline) such as E--15 (15% alcohol), E--20 (20%
alcohol), E--85 (85% alcohol) are NOT classified
as gasoline and are NOT approved for use in
2--stroke gasoline engines. Use of alternative
fuels will cause problems such as: improper
clutch engagements, overheating, vapor lock,
power loss, lubrication deficiency, deterioration
of fuel lines, gaskets and internal carburetor
components, etc. Alternative fuels cause high
moisture absorption into the fuel/oil mixture
leading to oil and fuel separation.

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 40:1. A 40:1
ratio is obtained by mixing 3.2 fluid ounces (95
ml) of oil with 1 gallon (4 liters) of unleaded
gasoline. Pour the entire contents of the 3.2
ounce (95 ml) container of oil into 1 gallon (4
liters) of gasoline to achieve the proper fuel
mixture. DO NOT USE automotive or marine
oil. These oils will cause engine damage.
When mixing fuel follow the instructions
printed on the 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: When starting engine,
hold the unit as illustrated. Do not set unit on any
