If the trunk is leaning on two sides (B zone) you must
first cut the top end halfway through (1) and then cut
the rest from below (2). This way you will avoid that
the internal trunk tension closes in on the cut, blocking
the chain and the chainsaw bar.
If you are going to cut with the trunk on one extreme
(A) you will have to start inversely. Firstly cut the trunk
halfway from the bottom and then from the top part
(2).
7.3.3. CUTTING BRANCHES FROM A FELLED TREE
It is important that
these branches are not
folded and/or under
tension. If the branch
to be cut is folded or
under tension y could
propel itself towards you when you cut it.
To cut a branch, in this case, cut 1/4 of the way on
the side where the branch has the tension and after
that cut the rest of the branch from the other side
(see diagram). This way you will avoid that the branch
tension closes the cut and/or blocks the chain and bar
of the machine.
7.3.4. CUTTING THE BRANCH FROM A TREE
To cut a branch from a tree
that is not touching the
ground cut a quarter of the
way from the bottom side (1)
and then cut the rest from the
top end (2).
This way you will help the aperture of the cut and that
the branch does not pull and damage the tree trunk.
7.3.5. BRANCH CUTTING OR SMALL TRUNK CUTTING
When cutting branches or small trunks use a strong
support such as an easel.
Never hold the trunk by using
your feet or asking someone
else to hold the wood for you.
8. MAINTENANCE AND SERVICE
The removal of security mechanisms, an
inappropriate maintenance, the substitution
of the bar and chain with non original
spares could cause severe corporal damages.
Always carry out maintenance work with the
machine unplugged from the mains.
Carry out the following maintenance checks prior to
working as well as when finishing your job to ensure
the good functioning of this machine in the future.
8.1. EXIT ORIFICE OF THE CHAIN OIL
Dismount the bar and
check that the oil orifice (A)
is not clogged.
8.2. SHARPNESS OF CHAIN TEETH
Attention!: An incorrectly sharpened chain increases
the risk of kick back as well as increasing the vibration
level and possible accidents!
