CS4518B CHAINSAW
• To buck a log on flat ground, make perpendicular cuts
through about half of the diameter of the log. Roll the
log and finish the cuts from the other side.
• To buck a pillowed or supported log, always make a
relieving cut through about 1/3 the diameter of the log
from the compressed side. Finish with a bucking cut
from the tension side of the log.
TIP: When cutting firewood, make sure you know the
optimum length of the finished firewood ahead of
time. Use the guide bar as an approximate length
gauge.
Pruning
Pruning is removing limbs from a standing tree, often for
purposes of maintaining a tree’s health or aesthetics. Always
work with a firm footing. Never cut from a stepladder. Do not
over reach. Do not cut above shoulder height.
1. Begin pruning by making a relief cut about 3 inches away
from the trunk of the tree to a depth of about 1/3 the
diameter of the branch.
2. Complete the cut from above, just inside of the initial
relief cut.
3. Finish pruning by making a smooth even cut nearly flush to
the trunk. It is recommended to only prune trees while they
are dormant in the fall and winter to reduce the risk posed
by disease or insects.
WARNING
BE CAREFUL WHEN CUTTING TREES WITH ROTTEN
HEARTWOOD (THE CORE OF THE TREE). THERE
IS AN INCREASED RISK THAT THE TREE COULD
SNAP OR SPLIT UNEXPECTEDLY DURING THE CUT.
CHECK FOR DEAD OR ROTTEN LIMBS BEFORE
BEGINNING THE CUT. DEAD LIMBS CAN VIBRATE
LOOSE FROM THE TREE AND FALL, STRIKING THE
OPERATOR.
CAUTION
LOGS AND LIMBS UNDER TENSION CAN SPRING
BACK WHEN CUT LOOSE. THIS LIGHTNING FAST
ACTION COULD CAUSE A LOSS OF CONTROL OF
THE CHAINSAW.
ONLY TRAINED AND EXPERIENCED
PROFESSIONALS SHOULD FELL TREES NEAR
OVERHEAD LINES AND BUILDINGS. A SLIGHT
MISJUDGMENT OF WIND DIRECTION OR NATURAL
LEAN OF A TREE COULD RESULT IN MAJOR
PROPERTY DAMAGE.
DO NOT CUT THROUGH THE HINGE. CUTTING
THROUGH THE HINGE INCREASES THE RISK OF
LOSING CONTROL OF THE FELLING DIRECTION.
ENGINE SAFETY PRECAUTIONS
If your product comes with a separate engine manual, be
sure to read and follow all safety and warning precautions
outlined there, in addition to any in this manual.
Preventing Carbon Monoxide Poisoning
• Always start and run engine outdoors. Do not start or
run engine in an enclosed area, even if doors or win-
dows are open.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may
be pulled into a building.
• Never run engine outdoors in a poorly ventilated area
where the exhaust fumes may be trapped and not
easily taken away. (Examples include: in a large hole
or areas where hills surround your working area.)
• Never run engine in an enclosed or partially enclosed
area. (Examples include: buildings that are enclosed
on one or more sides, under tents, car ports or base-
ments.)
• Always run the engine with the exhaust and muffler
pointed in the direction away from the operator.
• Never point the exhaust muffler towards anyone.
People should always be a safe distance away from
the operation of the engine and its attachments.
• Do not change the engine governor settings or over-
speed the engine.
Gasoline Fires and Handling Fuel Safely
• When storing extra fuel be sure that it is in an appro-
priate container and away from any fire hazards.
• Prevent fire and explosion caused by static electric
discharge. Use only nonmetal, portable fuel
WARNING
ENGINES GIVE OFF CARBON MONOXIDE, AN
ODORLESS, COLORLESS, POISONOUS GAS.
CARBON MONOXIDE MAY BE PRESENT EVEN
IF YOU DO NOT SMELL OR SEE ANY ENGINE
EXHAUST. BREATHING CARBON MONOXIDE
CAN CAUSE NAUSEA, FAINTING OR DEATH, IN
ADDITION TO DROWSINESS, DIZZINESS AND
CONFUSION.
IF YOU EXPERIENCE ANY OF THESE SYMPTOMS,
SEEK FRESH AIR AND MEDICAL ATTENTION
IMMEDIATELY.
ENGINE FUEL CAN BE FLAMABLE AND
EXPLOSIVE.
