Helpful hints
•
Do not force the saw into the cut. Apply only light pressure whilst running the
engine at full throttle.
•
If the saw chain gets caught in the cut, do not try to remove it by twisting the
guide or pulling forcibly. Use a lever or wedge to open up the cut so that the
saw chain is freed.
While cutting, always:
•
Run the chainsaw motor at full revs. This makes the job safer, as there is less
chance of pull-in or kick-back.
•
Position your body to the left of the chainsaw so if it kicks back uncontrollably,
it goes over your right shoulder, never stand in the cutting line of the saw.
•
Keep a firm grip with your left hand on the front handle, with your thumb
securely below the handle.
•
The swivel of your wrist in a kick-back situation will activate the chain brake.
•
Make sure the chain is tensioned correctly
Felling a tree
Warning!
Felling a tree should only be done by trained operators.
Decide the direction in which you wish the tree
to fall taking into account the direction of the
wind, the position of branches, lean of the tree,
ease of subsequent limbing and bucking and
other factors prevalent at the time.
1. Clear the area around the tree and make
sure that you have a good foothold and
clear retreat path.
2. Ensure that others in the area are aware of the felling and ensure people and
animals are well clear.
3. Make a notch cut one-third of the way into the tree on the felling side.
4. Make the felling cut on the opposite side to the initial notch and slightly higher
than the notch. As the felling cut gets close to the notch cut, the tree will
begin to fall.
5. Remove the saw from the cut, stop the engine with the on/off switch (11), put
the saw down and leave the area along the retreat path.
