This way, we will avoid the internal tension blocking
the chain and the chain bar.
If we are going to make a cut on a tree trunk that is
supported at one end with the other end in the air
(Section B of the drawing) we should proceed in the
opposite way. We will cut a third from underneath (1)
and we will then finish the cut from above (2).
7.5. CUTTING THE BRANCHES OFF A FALLEN TREE
It is important to check whether the branch is bent
and under tension or if it is in the air. A bent branch
will have internal tension and it could spring up when
you cut it.
To cut a bent branch, make a cut through a ¼ of the
branch towards the direction where it is bent and then
cut the part that remains from the other side. This
way, you will avoid the tension closing the cut and
blocking the chain.
7.6. CUTTING A BRANCH OFF A TREE
To cut one that is not touching the ground or that is on
a vertical tree always proceed by first cutting a ¼ of
the width of the branch from below (1) and then the
remaining ¾ from above (2).
This way will ease the opening
of the cut for the tool and it will
avoid the branch tearing and
harming the tree.
8. MAINTENANCE AND SERVICE
8.1. CARE AND MAINTENANCE AFTER USE
Carry out the following operations when you have
finished the cutting procedure to ensure that the
machine is kept in a perfect condition.
8.1.1. CHAIN OIL LUBRICATION HOLE
8.1.2. SHARPENING OF THE CHAIN TEETH
WARNING! : An improperly sharpened chain increases
the risk of rebound and vibrations increasing the risk
of injury!.
To ensure a smooth and safe cut keep the teeth on
the chain sharpened. The cutting teeth need to be
sharpened when:
• On cutting, sawdust appears instead of splinters.
• When sawing, extra effort is necessary.
• The cutting path is not straight.
• Vibration increases
• There is an increase in fuel consumption.
