• Kickback occurs if the kickback zone of the guide
bar contacts an object. Do not let the kickback zone
touch an object.
• A smaller bar tip radius decreases the force of the
kickback.
• Use a low kickback saw chain to decrease the
effects of kickback. Do not let the kickback zone
touch an object.
IT'S IMPORTANT TO NOTE THAT NO SAW CHAIN
CAN ENTIRELY ELIMINATE THE POSSIBILITY OF
KICKBACK.

PULL STROKE AND PUSH STROKE
You can cut through wood with 2 different strokes: pull
stroke and push stroke.
• The pull stroke is when you cut with the bottom
of the guide bar. The saw chain pulls through
the tree when you cut. In this position, you have
better control of the product and the position of the
kickback zone.
• The push stroke is when you cut with the top of the
guide bar. The saw chain pushes the product in the
direction of the operator.
IF THE SAW CHAIN IS CAUGHT IN THE TRUNK,
THE PRODUCT CAN KICKBACK TOWARD YOU.
HOLD THE PRODUCT TIGHTLY AND MAKE
SURE THAT THE KICKBACK ZONE OF THE
GUIDE BAR DOES NOT MAKE CONTACT WITH
AN OBJECT.

FELL A TREE
Before starting, ensure the trunk is clear and
establish a safe path of retreat.
Cut off all branches from your shoulder height and
below.
1.
Start cutting from the top down using a pull
stroke. Make sure that the tree is between you
and the product.
2.
Remove undergrowth from the work area around
the tree. Remove all cut-off materials from the
work area.
3.
Carefully inspect the surrounding area for
potential obstacles, such as stones, branches,
and holes. You must have a clear path of retreat
when the tree starts to fall. Your path of retreat
must be approximately 135 degrees away from
the felling direction.

The felling hinge
The most important procedure during tree felling is to
make the correct felling hinge. With a correct felling
hinge, you control the felling direction and make sure
that the felling procedure is safe. The thickness of the
felling hinge must be equal and a minimum of 10% of
the tree diameter.
IF THE FELLING HINGE IS INCORRECT OR TOO
THIN, YOU HAVE NO CONTROL OVER THE
FELLING DIRECTION.
