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 (C Fig.1)
and the undercut (D. Fig. 1), which is needed to fell the tree.

3.5cm

FIG. 1
- Begin with the face cut (C) on the side of the tree facing the direction
of the fall (E).
- The cut must be as deep as about ¼ of the trunk diameter (F).
- After this operation, make the cut (D) on the other side of the tree
at about 3-5 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:

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.

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.
- Keep your left arm as straight as possible.
13. Freeing a trapped saw.
In the case that the saw jamming during cutting is necessary:
- Turn off the chainsaw
- Do not pull or bend the saw
- Leverage with wedges into the trunk and pull the chain saw.
The above indications are general advice; the dangerous situation
or events could impose different actions which it is not possible to
envisage in these instructions, so act accordingly.

MAINTENANCE AND CLEANING

WARNING! All operations indicated below must be carried out with
the engine switched off and the spark plug unplugged.
WARNING! If in doubt, contact an authorised assistance centre.
WARNING! For operations not considered below please seek advice
from an authorised assistance centre.
WARNING! In the event of a fall, have the chainsaw checked.
Take care of your machine and clean it regularly to ensure that it
remains perfectly efficient and has a long lifetime.
Clean the machine with a soft brush or cloth.
Do not spray or wet the machine with water.
Do not use inflammable substances, detergents or solvents as these

to damage by chemical agents.
Bar and chain
- Tension and oil the chain when necessary
- Bring the chain to a specialised workshop for maintenance and
sharpening as needed.
- Turn the bar 180° following extensive use and when the chain is
replaced in order to create uniform wear along the entire bar.
