Bolens BL250 服务手册

• Read the instructions carefully. Be familiar with the controls

and proper use of the unit.

• Do not operate this unit when tired, ill or under the influ-

ence of alcohol, drugs or medication.

• 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 original equip-

ment manufacturer replacement line. Never use metal-rein-
forced 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.

• Squeeze the throttle control and check that it returns auto-

matically to the idle position. Make all adjustments or
repairs before using the unit.

• 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 attach-
ment. 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.

• 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 fuel-
ing or mixing fuel. Wipe up any spilled fuel from the unit
immediately. 

• 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.
