• To avoid the risk of re, do not leave the machine with the
engine hot on leaves or dry grass.
mWARNING! It takes specic training to use the machine
for felling and delimbing.
mWARNING! Prolonged exposure to vibrations can cause
injuries and neurovascular disorders (also called “Renaud’s
syndrome” or “white hand”), especially to people suering
from circulation disorders. The symptoms can regard the
hands, wrists, and ngers and manifest with loss of sensitivity,
torpor, itching, pain, and discoloring of or structural changes
to the skin. These eects can be worsened by low ambient
temperatures and/or by gripping the hand grips too tightly. If
the symptoms occur, the length of time the machine is used
must be reduced and a doctor consulted.
Checks During Work
• Checkingthechaintension
The chain tends to stretch gradually as you work, so you need
to check its tension frequently.
IMPORTANT! During the rst period of use (or after replacing
the chain), the chain tension must be checked more frequently
due to settling of the chain.
mWARNING! Never work with the chain loose, as it can
be hazardous if the chain slips out of its guides.
To adjust the chain tension, follow the instructions in
“Adjusting the Chain Tension” on pages 10.
• Checkingtheoildelivery
IMPORTANT! Never use the machine without lubrication! You
can check the oil level in the tank through the transparent
gauge. Make sure you ll up the oil tank every time you use
the machine. For best results, use only a good quality bar and
chain oil designed specically for use with chain saws.
mWARNING! Make sure the bar and the chain are in
place when you check the oil delivery.
Start the motor and check if the chain oil is delivered as shown
below (Fig. 15).
Cutting Techniques
Before felling or delimbing for the rst time, practice sawing
logs on the ground or on trestles, so that you can get familiar
with the machine and the most suitable sawing techniques.
mWARNING! Always hold the machine with both hands
when sawing.
mWARNING! Stop the motor immediately if the chain
stops during sawing. Beware of kickback, which can occur if
the bar contacts an obstacle.
• Fellingatree
i) When bucking and felling are performed by two or more
people at the same time, the felling operation should be
separated from the bucking operation by a distance of at
least twice the height of the tree being felled. Trees should
not be felled in a manner that would endanger any person,
strike any utility line or cause any property damage. If the
tree does make contact with any utility line, the company
should be notied immediately.
ii) The chain saw operator should keep on the uphill side of
the terrain as the tree is likely to roll or slide downhill after
it is felled.
iii) An escape path should be planned and cleared as
necessary before cuts are started. The escape path should
extend back and diagonally to the rear of the expected line
of fall as illustrated (Fig. 16).
iv) Before felling is started, consider the natural lean of the
tree, the location of larger branches and the wind direction
to help you judge which way the tree will fall.
v) Remove dirt, stones, loose bark, nails, staples, and wire
from the tree.
