1)Begin the felling notch by lining up the guide bar perpendicular to the desired felling direction.
2)Make a downward cut at
Warning
Inexperienced users should never attempt to cut trees with rotten heartwood (the core of the tree). There is an increased risk that the tree couldsnaporsplitunexpectedlyduringthecut. Also check for dead or rotten limbs prior to beginning the cut. Dead limbs can vibrate loose from the tree and fall, striking the operator.
3)Finish the notch by making a horizontal cut perpendicular to the desired felling direction.
4)Remove the resultant piece.

1)Begin the felling cut by making a horizontal cut perpendicular to the intended felling direction and approximately
2)Leave approximately 1/10 of the tree’s diameter uncut. This will form the hinge.
3)Drive plastic or wooden wedges into the felling cut to control the fall.
4)As the tree begins to fall, alert others and immediately evacuate the area around the tree.
Limbing a Felled Tree
“Limbing”refers to removing the limbs from a fallen tree. There is an extremely high danger of kickback during the limbing operation. Do notworkwiththenoseoftheguidebar,asthiscouldcauseakickback. Use extreme caution and avoid contact between the nose of the bar and the log or other limbs. Do not stand on the log while limbing it as the log may roll as limbs are removed and the center of gravity shifts.
Start limbing by removing limbs from the top side of the log, leaving limbs on the bottom to support the log up off the ground. Limbs under tension may pinch the guide bar and saw chain. Shut off the engine and lift the limb to remove the bar safely.
Bucking a Log
“Bucking” is the
•When bucking small logs, place them in a “V” shaped bucking horse to keep them at a working level. Never allow a bystander to hold the log. Never hold the log with your leg or foot.
•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.
Caution
Logs and limbs under tension can spring back when cut loose. This lightning fast action could cause a loss of control ofthe chainsaw.
Caution
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.
Caution
Do not cut through the hinge. Cutting through the hinge increases the risk of losing control of the felling direction.
•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 trunkofthetreetoadepthofabout1/3thediameterofthebranch.
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. Itisrecommendedtoonlyprunetreeswhiletheyaredormant in the fall and winter to reduce the risk posed by disease or insects.
