from work area a minimum of 15 meters when
starting or operating unit. Do not point blower
nozzle in the direction of people or pets.
FUEL SAFETY
D Eliminate all sources of sparks or flame (in-
cluding smoking, open flames, or work that
can cause sparks) in the areas where fuel is
mixed, poured, or stored.

must be stopped and the impeller blades no
longer turning to avoid serious injury from the
rotating blades.
D This garden blower is only designed for blow-
ing away leaves and other debris on the
ground.
D Inspect unit before each use for worn, loose,
missing, or damaged parts. Do not use until
unit is in proper working order.
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 T o 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 sur-
faces such as ladders, trees, steep slopes,
rooftops, etc. Keep firm footing and balance at
all times.
D Never place objects inside the blower tubes;
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. When using your unit as a blower,
always install blower tubes.
D Check air intake opening and blower tubes
frequently, always with engine stopped and
spark plug disconnected. Keep vents and discharge tubes free of debris which can accumulate and restrict proper air flow.
D Never place any object in the air intake open-
ing as this could restrict proper air flow and
cause damage to the unit.
