Felling a Tree
1.
Decide the felling direction considering the wind, lean of the tree, location of heavy branches, ease
of job after felling and other factors.
2.
While clearing the area around the tree, arrange a good foothold and retreat path.
3.
Make a notch cut one-third of the way into the tree on the felling side.
4.
Make a felling cut from the opposite side of the notch and at a level slightly
higher than the bottom of the notch.

When you are felling a tree, be sure to warn your neighbouring workers of the danger.
Bucking and Limbing
Always ensure your foothold. Do not stand on the log you are cutting.
•
Be alert to the rolling over of a cut log, especially when working on a slope. Stand on the uphill side
of the log.
Before starting work, check the direction of bending force inside the log to be cut. Always finish cutting
from the opposite side of bending direction to prevent the guide bar from being caught in the cut.
A log lying on the ground.
Saw down halfway, then roll
the log over and cut from the
opposite side.
A log hanging off the ground.
In area A, saw up from the
bottom one-third and finish by
sawing down from the top.
In area B, saw down from the
top one third, and finish by
sawing up from the bottom.
Cutting a limb from a fallen tree.
Check to see which side the limb is
bent. Then make the initial cut
from the bent side and finish by
sawing from the opposite side.
(Be alert to the springing back of a
cut limb).
Pruning a standing tree.
Cut up from the bottom, finish
down from the top.
Do not use an unstable foothold or ladder. Do not overreach. Always use both hands to hold saw.
Maintenance
Before cleaning, inspecting, or repairing your unit, make sure that engine has stopped and is cool.
Disconnect the spark plug to prevent accidental starting.
Maintenance after each use
Air Filter
Dust on the cleaner surface can be removed by tapping a corner of the cleaner against a
hard surface.
To clean dirt in the meshes, split the cleaner into halves and brush in gasoline. When using
compressed air to clean, blow from the inside.
Oil Port
Dismount the guide bar, then check the oiling port for clogging.
Guide Bar
When the guide bar is dismounted, remove any sawdust in the bar groove and the oiling port.
Grease the nose sprocket from the feeding port on the tip of the bar.
Other steps
Check for fuel leakages, loose fastenings and physical damage to the chainsaw, especially the handle joints
and guide bar. If any defects are found, do not use the chainsaw. Contact the Kogan customer support
team.
