7. Felling trees in relation to the saw's cutting capacity.
Do not make cuts on diameters greater than the maximum cutting
length (see technical specifications). It is always better not to exag-
gerate the diameter of the cut.
8.How to control the fall direction of the tree being cut.
Usually, felling a tree consists of two main cuts, the face cut and the
undercut which is needed to fell the tree.
direzione di caduta
direction of fall
intaglio
notch
FIG. 1
- Begin with the face cut on the side of the tree facing the direction
of the fall.
- The cut must be as deep as about 1/3 of the trunk diameter.
- After this operation, make the cut on the other side of the tree at
about 5 cm above the height of the face cut (Fig. 1).
- Do not walk in front of the tree on the fall side after you have made
the cut.
- IMPORTANT! Before proceeding with the final cut, check that there
are no persons, animals, or objects in the fall area.
- IMPORTANT! When the tree begins to fall, extract the chain saw
from the cut, lay it on the ground, and leave the area quickly along
the escape route.
9. Using wedges for felling trees
- Use wooden or plastic wedges (G Fig.2) to prevent the bar or the
chain from getting lodged in the trunk.

- IMPORTANT! When the tree begins to fall, extract the chain saw
from the cut, lay it on the ground, and leave the area quickly along
the escape route.
10. Cutting branches (debranching)
Introduction:
This operation consists of cutting the branches of felled trees.
Note: Do not cut the branches that support the felled tree before
cutting it in pieces. (Fig.3)
- IMPORTANT! Do not climb onto the trunk to cut it.

1. Trunk supported along its entire length:
Cut from the top down (Fig.4).

2. Trunk supported only on one end:
First cut from below for 1/3 of the trunk and then from the top down
until the previous cut has been reached. (Fig 5).

3. Trunk supported on both ends.
First cut from above for 1/3 of the trunk and then from the bottom up
until the previous cut has been reached. (Fig.6).

12. Cutting wood on supports (trestles)
In order to work easily and safely, it is important to maintain a correct
position:
- Distribute your weight on both feet.
- Hold the chain saw to your right while cutting.
CLEANING
IMPORTANT! Before carrying out any operation on the chain saw,
disconnect the plug from the power supply.
- Regularly remove dirt and wood deposits from the motor cooling
vents (nr. 14 Fig. A Pos. 1).
Cooling the motor is very important and this operation must be carried
out regularly even during use, if deposits are noticed.
It is recommended that a dry brush be used to clean the cooling vents.
- After every extensive working period, disassemble the bar and chain
and clean them with a brush.
Carefully remove the wood deposits from the sprocket (nr. 19), near
the bar fixing pin (16), and from under the housing.
- Keep the area near the oil tank cap and the inspection window clean
so that no impurities enter the tank.
- Clean the surfaces of plastic parts with a rag, a brush, or a soft
brush.
- If the chain saw is not used for a long period of time, it is recommended
that the you empty the tank, clean the chain and bar in an oil bath, and
store them in greaseproof paper.
