CHECKING THE MACHINE
Before starting work please:
– check that all the screws on the machine and
the bar are tightly fastened;
– check that the chain is sharp and there are no
signs of any damage;
– check that the air filter is clean;
– check that the protection devices are well fas-
tened and working efficiently;
– check that the handgrips are well fastened;
– check that the chain brake is working effi-
ciently.
PREPARING THE FUEL
This machine is fitted with a two-stroke engine
which requires a mixture of petrol and lubricating
oil.
Using petrol alone will damage the motor and will cause for invalidation of
the warranty.
Only use quality fuels and
oils to maintain high performance and guarantee
the duration of the mechanical parts over time.
• Petrol characteristics
Only use unleaded petrol with a fuel grade of at
least 90 N.O.
Unleaded petrol tends to
create deposits in the container if preserved for
more than 2 months. Always use fresh petrol!
• Oil characteristics
Only use top quality synthetic oil specifically for
two-stroke engines.
Your dealer can provide you with oils which have
been specifically developed for this type of
engine, and which are capable of guaranteeing a
high level of protection.
The use of these oils makes it possible to prepare a 2% mixture, consisting in 1 part oil to 50
parts petrol.
In the event that no specific oil is available, it is
IMPORTANT
IMPORTANT
IMPORTANT
possible to use a mineral lubricating oil for
engines (class FA or FB), where in this case the
mixture must be 4%, i.e. 1 part oil and 25 parts
petrol.
•Preparation and preservation of the fuel
mixture
Petrol and the fuel mixture are highly inflammable!
– Keep the petrol and fuel mixture in homolo-
gated fuel containers, in safe place, away
from any flames or heat sources.
– Never leave the containers within the reach
of children.
– Never smoke whilst preparing the mixture
and avoid inhaling the petrol fumes.
The chart indicates the amount of petrol and oil
to use to prepare the fuel mixture according to
the type of oil used.
To prepare the fuel mixture:
– Place about half the amount of petrol in a
homologated tank
– Add all the oil, according to the chart.
– Add the rest of the petrol.
– Close the top and shake well.
The fuel mixture tends to
age. Do not prepare excessive amounts of the
fuel mixture to avoid deposits from forming.
Keep the petrol and fuel mixture containers separate and easily identifiable to
avoid the mistake of using one in place of the
other.

REFUELLING
Never smoke whilst refuelling and avoid inhaling the petrol fumes.
Carefully open the tank top
as pressure could have formed inside.
Before refuelling:
– Shake the fuel mixture container well.
– Place the machine on a flat stable surface,
with the fuel tank cap facing upwards.
– Clean the fuel tank cap and the surrounding
area to avoid any dirt from entering the tank
during refilling.
– Carefully open the fuel tank cap to allow the
pressure inside to decrease gradually. Use a
funnel to refill and avoid filling the tank to the
brim.
Always close the fuel tank
cap firmly.

WARNING!
!
WARNING!
!
DANGER!
IMPORTANT
Immediately clean all
traces of fuel which may have dripped on the
machine or the ground and do not start the
engine until the petrol fumes have dissipated.
CHAIN LUBRICANT
Only use oil with SAE 30 viscosity, specifically for lubricating chains. Do not
use oil containing impurities, to avoid clogging
the tank filter and permanently damaging the
oiler.
It is essential that you use good quality oil to
lubricate the cutting parts effectively. Used or
poor quality oil does not guarantee good lubrication and reduces the duration of the chain and
bar.
It is always worth topping up the oil tank completely (using a funnel) every time you refuel.
Since the oil tank capacity is enough to guarantee that the fuel runs out first, you will avoid the
risk of operating the machine without lubricant.
IMPORTANT
!
WARNING!
means starting it after at least 5 minutes from
when it was switched off or after refuelling.
To start the engine (Fig. 12):

back uncontrollably.
8. Pull the starter rope again until the engine
starts as normal.
9. When the engine has started, press the throt-
tle trigger to disconnect the starter and allow
the engine to idle.
Do not let the engine run at
high power with the chain brake engaged, as this
could cause overheating and damage to the
clutch.
10. Let the engine run idle for at least 1 minute
before using the machine.
If the starter rope is pulled
repeatedly with the choke on, it may flood the
engine and make starting difficult.
If you have flooded the engine, remove the spark
plug and gently pull the handle on the starter
rope to eliminate any excess fuel; then dry the
spark plug electrodes and replace it on the
engine.
• Hot starting

IMPORTANT
IMPORTANT
IMPORTANT
!
WARNING!
USE OF THE ENGINE (Fig. 14)
The chain speed is regulated by the throttle trigger (1) on the rear handgrip (2).
The throttle trigger only works if the lockout (3) is
pressed at the same time.
The movement is transmitted from the engine to
the chain by a centrifugal mass clutch that prevents the chain from moving when the engine is
running at minimum speed.
Never use the machine if
the chain moves when the engine is running
idle; if this is the case regulate the minimum
rate (see chap.8) and if the problem persists
please contact your dealer.
The correct running speed will be achieved by
pressing the throttle trigger (1) as far as possible.
Avoid using the engine at full
power for the first 6-8 working hours.
STOPPING THE ENGINE (Fig. 14)
To stop the engine:
– Release the throttle trigger (1) and allow the
engine to run idle for a few seconds.
– Set the switch (4) to “STOP”.
When you have reduced
speed to a minimum, it will take a few seconds for the chain to stop.

out lubrication! The oil tank may get almost
empty every time the fuel runs out. Make sure
you top up the oil tank every time you refuel the
chain-saw.
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. 15).
In models P 44(x) and P 48(x), you can adjust
the chain oil flow using a screwdriver on the
adjuster screw (1) of the oiler, which is on the
bottom of the machine (Fig. 15).
DIRECTIONS FOR USE AND CUTTING TECHNIQUES
Before felling or delimbing for the first time, practise sawing logs on the ground or on trestles, so
that you can get familiar with the machine and
the most suitable sawing techniques.
Always hold the machine
with both hands when sawing.
Stop the engine immediately if the chain stops during sawing.
Beware of kickback, which can occur if the
bar contacts an obstacle.
Kickback occurs when the tip of the chain
comes in contact with an object or when the
wood contracts and jams the chain during
sawing.
This contact with the tip of the chain can
cause a rapid backward motion, pushing the
guide bar up and towards the operator. This
also happens when the chain is jammed
along the upper part of the bar. In both cases,
kickback can cause the operator to lose control of the chain-saw, leading to serious consequences.

10 USING THE MACHINE
7. USING THE MACHINE
• Delimbing (Fig. 16)
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. 17)
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.
5. Cut the tree on the other side, slightly above
the bottom of the notch, leaving the uncut
wood to act as a “hinge” (1) of approx. 5-10
cm.
6. Reduce the thickness of this hinge without
pulling out the bar, until the tree falls.
7. In particular or unstable conditions, you can
complete felling by inserting wedges (2) on
the opposite side of the fall, and hitting them
with a hammer until the tree falls.

WARNING!
!
WARNING!
• Bucking (Fig. 18)
Be careful of where the
branches are lying on the ground, the risk of
them being under tension, the direction the
branch may go during cutting and the risk of
the tree being unstable after the branch has
been cut..
1. Check the direction in which the branch is
attached to the tree
2. First cut on the side where the branch bends
and then finish cutting on the opposite side.
• Sawing logs (Fig. 19)
It is easier to saw a log using the spiked bumper.
1. Dig the spiked bumper into the log and use it
as a pivot. Cut with an arched motion to make
the bar penetrate the wood.
2. Repeat several times if necessary, changing
the point where you plant the spiked bumper.
•
Sawing a log on the ground (Fig. 20)
Cut up to half the diameter, roll the log over and
finishing sawing on the other side.
•
Sawing a raised log (Fig. 21)
1. If you are sawing the overhanging end of a
supported log (A), first cut a third of the diameter from the bottom upwards, then finish
from the top.
2. If you are sawing between two supports (B),
cut a third of the diameter from the top downwards, then finish from the bottom.
END OF OPERATIONS
When you have finished your work:
– Switch off the engine as indicated above
(Chap. 6)..
–Wait for the chain to stop and then mount the
bar cover.

WARNING!
USING THE MACHINE 11
EN
Correct maintenance is essential to maintain the
original efficiency and safety of the machine over
time.
During maintenance operations:
– Remove the spark plug cap.
–Wait until the engine is sufficiently cold.
– Use protective gloves when handling the
bar and chain.
– Keep the bar protection devices on, except
when intervening directly on the bar or the
chain.
– Never dispose of oils, fuel or other polluting
materials in unauthorised places.
CYLINDER AND SILENCER
To reduce fire risks, periodically clean the cylinder flaps with compressed air and clear the
silencer area to get rid of sawdust, branches,
leaves or other debris.
STARTING SYSTEM
To avoid overheating and damage to the engine,
always keep the cooling air vents clean and free
of sawdust and debris.
The starter rope must be replaced as soon as it
shows signs of wear.
CLUTCH UNIT
Keep the clutch bell free of sawdust and debris.
Have your dealer check the greasing of the internal bearing every 30 hours (approx.).
CHAIN BRAKE
Regularly check the efficiency of the chain brake
and the condition of the metal band around the
clutch bell.
Replace this band when the points in contact
with the clutch bell wear down to about half the
thickness of the two ends not subject to rubbing.
!
WARNING!
CHAIN SPROCKET (Fig. 22)
Regularly check the condition of the sprocket
and replace it when wear exceeds 0.5 mm.
Do not mount a new chain with a worn sprocket
or vice-versa.
CHAIN CATCHER
This is an important safety device that restrains
the chain if it breaks or degrooves.
Regularly check the condition of the chain
catcher and replace it if it gets damaged.
NUTS AND SCREWS
Periodically check that all the nuts and screws
are securely tightened and the handgrips are
tightly fastened.
CLEANING THE AIR FILTER (Fig. 23)
Cleaning the air filter is
essential to guarantee the efficiency and duration
of the machine. Do not work with a damaged filter or without a filter, as this could permanently
damage the engine.
It must be cleaned after every 8-10 working
hours.
Clean the filter as follows:
– Remove the cover (1) and filter element (2).
– Gently tap the filter element (2) to remove the
dirt and, if necessary, clean it with low pressure compressed air .
The filter element (2) must
never be washed and must be replaced if it is too
dirty or damaged.
– Fit the filter element (2) and the cover (1) back
on.
– In models P43(x) - P44(x) - P47(x) - P48(x),
first attach the filter element (2a) to the cover

(1a) and then fit these assembled parts on the
machine.
CHECKING THE SPARK PLUG (Fig. 24)
Periodically remove and clean the spark plug
using a metal brush to get rid of any deposits.
Check and reset the correct distance between
the electrodes.
Replace the spark plug and fasten it firmly using
the supplied wrench.
The spark plug must be replaced with one with
the same characteristics whenever the electrodes have burnt or the insulation has worn, and
in any case every 100 working hours.
TUNING THE CARBURETTOR
The carburettor is tuned by the manufacturer to
achieve maximum performance in all situations,
with a minimum emission of toxic gas in compliance with the regulations in force.
When performance is poor, first check that the
chain runs smoothly and the bar rails are not distorted, then contact your dealer to check the
carburetion and the engine.
•
Tuning minimum speed
The minimum speed must
only be tuned if the chain moves when the
engine idles.
Speed is reduced by turning the screw marked
“T” or “MIN - IDLE” anti-clockwise until the chain
stops moving. The engine should continue to run
as normal.
If the engine does not idle smoothly, turn the
screw clockwise to increase the speed.
The chain must not move
when the engine idles; contact your dealer if
you are not able to tune it to your satisfaction.

WARNING!
SHARPENING THE CHAIN
To ensure that the chainsaw works safely and efficiently, it is essential
that the cutting components are well-sharpened.
Sharpening is necessary when:
• The sawdust looks like dust.
• Cutting becomes more difficult.
• The cut is not straight.
•Vibrations increase.
• Fuel consumption increases.
A specialized centre will sharpen the chain using
the right tools to ensure minimum removal of
material and even sharpness on all the cutting
edges.
If you sharpen the chain yourself, use special
round-section files with the right diameter
depending on the type of chain (see “Chain
Maintenance Table”). You need a certain amount
of skill and experience to avoid damaging the
cutting edges.
Sharpen the chain as follows (Fig. 25):
– Switch off the engine, release the chain brake
and secure the bar with the chain in a vice so
that the chain can run smoothly.
–Tighten the chain if it is loose.
– Mount the file in the guide and then insert it in
the tooth at a constant angle from the cutting
edge.
– Sharpen in a forward motion a few times and
repeat this on all the cutting edges facing the
same way (right or left).
–Turn the bar over in the vice and repeat on all
the other cutting edges.
– Check that the limiter tooth does not stick out
further than the inspection instrument and file
any projecting parts with a flat file, rounding
off the edge.
– After sharpening, remove all traces of filing
and dust and lubricate the chain in an oil bath.
Replace the chain whenever:
– The length of the cutting edges reduces to 5
mm or less;
– There is too much play between the links and
the rivets.

BAR MAINTENANCE (Fig. 26)
To avoid asymmetrical wear on the bar, make
sure it is turned over periodically.
To keep the bar in perfect working order, proceed as follows:
–grease the bearings on the nose sprocket (if
present) with the syringe;
–clean the bar groove with the scraper;
– clean the lubrication holes;
– with a flat file, remove burr from the edges and
level off the guides.
Replace the bar whenever:
– the groove is not as deep as the height of the
drive links (which must never touch the bot-
tom);
– the inside of the guide is worn enough to
make the chain lean to one side.
EXTRAORDINARY MAINTENANCE
All maintenance operations not foreseen in this
manual must be performed exclusively by your
dealer.
All and any operations performed in unautho-
rised centres or by unqualified persons will totally invalidate the warranty.
STORAGE
After every work stint, clean the machine thoroughly to remove all dust and debris, and repair
or replace any faulty parts.
The machine must be stored in a dry place away
from the elements and with the bar cover correctly fitted.
LONG PERIODS OF DISUSE
If you are not going to use
the machine for a period of more than 2-3
months, we recommend you do a few things
before putting it away. This will make it easier
when you want to use the machine again and will
also prevent permanent damage to the engine.
