Operator's Manual
CS4518B CHAINSAW
• If an object becomes lodged in the saw, turn engine
off, remove the wire from the spark plug and secure,
allow to cool before attempting to remove the foreign
object.
• The clutch will transfer maximum power after about
two hours of normal operation. During this break-in
period clutch slippage may occur. The clutch should
be kept free of oil or other moisture for efficient
operation.
• Never cut in high wind, bad weather, when visibility
is poor, or in very low temperatures. Always check
the tree for dead branches that could fall during the
felling operation.
• Never start cutting until you have a clear work area,
secure footing and a planned retreat path away from
the falling tree.
• Always hold the chainsaw firmly with both hands
when the engine is running. Use a firm grip with
thumb and fingers encircling the chainsaw handles.
• When carrying from one place to another, always stop
the engine and hold the saw with the guide bar and
saw chain behind you and the muffler away from your
body.
• Always inspect the chainsaw for worn, loose, or dam-
aged parts. Never operate a chainsaw that has been
damaged, improperly adjusted, or is not completely
and securely assembled.
• Use extreme caution when cutting small brush and
saplings. Thinner material may be caught by the
chain and could whip back toward you or pull you off
balance.
• When cutting limbs under tension, stay alert for
“spring back” so you are not struck when the tension
in the wood fibers is released.
• Always shut off the engine before setting the chain-
saw down.
• Keep the handles dry, clean, and free of lubricants, oils
and fuel.
Precautions to Avoid Kickback:
• Always grip the chainsaw firmly with both hands; the
right hand on the rear handle, and the left hand on
the forward grip.
• Make certain the area in which you are cutting is free
from obstructions. Do not let the guide bar nose
come into contact with a log, branch, rock or other
objects while cutting. Such contact could result in a
kickback.
• Always make cuts at high engine speeds.
• Do not over-reach or cut above shoulder height.
• Always maintain a sharp and clean saw chain. Follow
manufacturer’s sharpening and maintenance instruc-
tions for the saw chain.
• Only use replacement bars and chains specified by
the manufacturer or an appropriate equivalent.
Sawing
• This saw is provided for the sole intended purpose of
cutting wood. Do not cut other materials with this
saw.
• Do not attach other tools or accessories to the output
shaft of the power unit. Doing so will void the manu-
facturer’s warranty.
• Do not apply excessive pressure to force the saw
through the cut. Run the engine at full throttle and
apply only light pressure.
• Always maintain a firm footing.
• Never cut from a stepladder or while in a tree.
Tip contact in some cases may cause a
lightning-fast reverse action, kicking the
guide bar up and back toward the operator.
Pinching the saw chain along the top of the
guide bar may push the guide bar and the
saw unit backward toward the operator.
Either of these reactions may cause the
operator to lose control of the chainsaw,
which could result in serious personal injury
or death.
Do not rely exclusively on the safety devises
built into your saw. As a chainsaw user, it is
your responsibility to understand the inher-
ent dangers of chainsaw use and the precau-
tions necessary to minimize those dangers.
Kickback may occur when the guide
bar nose or tip comes into contact with
a foreign object, or when the “saw kerf”
(gap in the wood being cut) closes in
on the bar and pinches the saw chain.
