7. USING THE MACHINE
DANGER!
This machine's
generates
electromagneticfield, but it is not pos-
sible to exclude the possibility of
interference on any active or pas-
sive medical devices that operators
may be wearing; this could be risky
for their health conditions. All those
using medical devices should always
consult their GP, or the device manu-
facturer, before using this machine.
CAUTION!
It takes specific training to use the
machine for felling and delimbing.
1. CHECKS DURING WORK
Checking the chain tension
The chain tends to stretch gradually as you work,
so you need to check its tension frequently.
During the first period of use (or after re-
placing the chain), it must be checked
more frequently due to settling of the
chain.
CAUTION!
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 Chapter 5. CHECKING THE CHAIN
Checking the oil delivery
Never use the machine without lubrica-
tion! The oil tank may get almost empty
every time the fuel runs out. Make sure
you top up the oil tank every time you re-
fuel the chain saw.
CAUTION!
Make sure the bar and the chain are in
place when you check the oil delivery.
Start the engine, keep it running at medium power
and check if the chain oil is delivered as shown in
the figure (Fig. 12).
Only for mod. 46 and 52
You can adjust the chain oil flow using a screwd-
river on the adjuster screw (1) of the oiler, which
is on the bottom of the machine (Fig. 12).

2. DIRECTIONS FOR USE AND CUTTING
TECHNIQUES
Before felling or delimbing for the first time, prac-
tise sawing logs on the ground or on trestles, so
that you can get familiar with the machine and the
most suitable sawing techniques.
CAUTION!
When running, the machine must al-
ways be firmly held in both hands,
with the right hand on the front hand
grip and the left hand on the rear hand
grip,even if the operator is left-han-
ded.
CAUTION!
Stop the engine immediately if the
chain stops during sawing. Beware
of kickback, which can occur if the
barcontacts an obstacle.
Delimbing (Fig. 13)
CAUTION!
Make sure there is nothing or nobody
in the area where the branches will fall
1. Stand opposite the branch you want to cut.
2. Start cutting lower branches followed by the
higher ones.
3. Cut downwards to prevent the bar from get-
ting jammed.
Felling (Fig. 14)
CAUTION!
When felling on slopes, always stand
uphill from the tree and check that the
felled trunk cannot cause damage if it
rolls down the hill.
1. Decide where the tree should fall – you should
consider the wind, the natural lean of the tree,
the position of the heaviest branches and how
easy the work is after felling, etc.
2. Clear the area around the tree and find a sta-
ble place to stand.
3. Plan obstacle-free escape routes at a 45°
angle back and away from the direction of
fall. These routes must allow you reach a
safe area at a distance of about 2.5 times the
length of the tree to be felled.
4. On the side of the fall, mark a felling notch
around a third of the trunk's diameter.
