Chain Saw

WARNING
￭ The saw chain has many sharp cutters. Contacting the
cutters may result in serious laceration injuries, even if the
chain is not moving. To reduce the risk of such injuries:
– Keep hands, feet and other parts of your body away
from the chain.
– Wear heavy-duty work gloves when handling the
chain saw or its chain.
– Never touch a moving chain with your hand or any
other part of your body.
– Cover the guide bar with a chain scabbard before
transporting or storing the chain saw to reduce the
risk of injury from inadvertent contact.
￭ Reactive forces, including kickback, can be dangerous.
– Pay special attention to the section of this instruction
manual on "Kickback and Other Reactive Forces,"
@ 6.
￭ To reduce the risk of personal injury to the operator and
bystanders:
– Always release the throttle trigger, engage the chain
brake and shut off the engine before assembling,
transporting, adjusting, inspecting, cleaning,
servicing, maintaining or storing the chain saw.
– Shut off the chain saw anytime it is not in use.
￭ To reduce the risk of fire and explosion:
– Only use the spark plug specified in this instruction
manual and make sure it and the ignition lead are
clean and in good condition.
– Always press the spark plug boot snugly onto the
spark plug terminal of the proper size.
– Never test the ignition system with the spark plug
boot removed from the spark plug or with a removed
spark plug.
