While Operating - MTD YARD-MAN YM90 Manuel De L'utilisateur

• Children under the age of 15 must not use the unit;
teens may operate the unit with adult guidance.
• Inspect the unit before use. Replace damaged parts.
Check for fuel leaks. Make sure all fasteners are in
place and secure. Replace cutting attachment parts
that are cracked, chipped or damaged in any way.
Make sure the cutting attachment is properly installed
and securely fastened. Be sure that the cutting
attachment shield is properly attached, and positioned
as recommended. Failure to do so can result in
personal injury to the operator and bystanders, as well
as damage to the unit.
• Use only 0.095-inch (2.41 mm) diameter Genuine
Factory Parts™ replacement line. Never use metal-
reinforced line, wire, chain or rope. These can break
off and become dangerous projectiles.
• Be aware of risk of injury to the head, hands and feet.
• Clear the area to be cut before each use. Remove
rocks, broken glass, nails, wire, string and other
objects which may be thrown or become entangled in
the cutting attachment. Clear the area of children,
bystanders and pets; keep them outside a 50-foot
(15 m.) radius, at a minimum. Even then, they are still
at risk from thrown objects. Encourage bystanders to
wear eye protection. If you are approached, stop the
unit immediately.
• Squeeze the throttle control and check that it returns
automatically to the idle position. Make all adjustments
or repairs before using the unit.
Safety Warnings for Gas Trimmers
WARNING: Gasoline is highly flammable,
and its vapors can explode if ignited. Take
the following precautions:
• Store fuel only in containers specifically designed and
approved for the storage of such materials.
• Always stop the engine and allow it to cool before
filling the fuel tank. Never remove the fuel tank cap or
add fuel when the engine is hot. Never operate the unit
without the fuel cap securely in place. Loosen the fuel
tank cap slowly to relieve any pressure in the tank.
• Add fuel in a clean, well-ventilated outdoor area where
there are no sparks or flames. Remove the fuel cap
slowly, and only after the engine stops. Do not smoke
while fueling or mixing fuel. Wipe up any spilled fuel
from the unit immediately.
• Avoid creating a source of ignition for spilled fuel. Do
not start the engine until fuel vapors dissipate.
• Move the unit at least 30 feet (9.1 m) from the fueling
source and site before starting the engine. Do not
smoke. Keep sparks and open flames away from the
area while adding fuel or operating the unit.
