the alignment of the moving parts, potentially damaged components, the general
assembly, and other aspects that may influence correct operation. If ever the protective
components or other elements are damaged, you must have them properly repaired
or replaced by an authorised customer service centre. Do not use the tool if it is not
working correctly.
18. IMPORTANT!
The use of accessories other than those recommended in this instruction manual may
cause accidents or injury and it is forbidden.
19. Have the chain saw repaired only by qualified professional technicians.
This tool complies with all required safety standards. Repairs must be carried out
by qualified technicians and only original spare parts must be used. Otherwise, the
operator may face serious danger when using this tool.
20. Protection from kickbacks.
WARNING! There may be kickbacks if the end or the top of the bar come into contact
with an object or when wood becomes lodged in the chain of the chain saw during
cutting. In some cases this contact may cause kickbacks, pushing the bar forcefully
backwards towards the operator. The snagging of the chain along the upper part of
the bar may push the bar forcefully backwards towards the operator. Both of these
reactions may result in a loss of control or cause serious injury to the operator. It is
very important to follow the instructions below very carefully in order to minimize the
risk of kickback.
A. Hold the chain saw firmly: hold it firmly with both hands when the engine is running, with
your right hand on the rear hand grip and your left hand on the front hand grip.
B. Avoid unsafe movements.
C. Always make sure that your stance is supported and balanced.
D. Check that the tip of the bar does not touch trunks, branches, the ground or other
obstacles.
E. Do not cut branches higher than shoulder height.
F. Use equipment like chains, bar protection, chain brakes, and special bars to reduce
risks associated with kickbacks.
G. Use only bars and chains specified by the manufacturer.
21. Fuel
Only use an oil-petrol mixture. Use petrol without lead Eurosuper with min. 90 octanes.
Do not use old or dirty mixtures. Any damage caused by incorrect fuel usage is not
covered by the warranty.
22. Do not use the chain saw...
... if it is damaged, inadequately regulated, or assembled incompletely or unsafely.
Check that the chain of the chain saw stops when the lever is released. Do not use
the chain saw if the accelerator lever does not function correctly.
23. Do not carry out operations or repairs for which you have no competence and expe-
rience.
24. Do not use the chain saw with only one hand!
Hold both handles firmly. Hold it in front of you, never on the side.
25. Keep your hands clean, dry, and free from oil and grease.
26. Do not leave dirt, residue or sawdust in the engine.
27 The chain saw is to be used exclusively by qualified personnel trained in tree mainte-
nance.
28. The chain saw was designed for non-professional use.
It was not designed for heavy duty or continuous jobs.
29. Do not use the chain saw for oversized jobs that would require larger equipment.
30. Carefully read all instructions to use the machine properly.
31. Before use, always check that the tension of the chain has been properly adjusted.
A chain that is too loose may be dangerous and cause injury.
32. Whoever is using the tool for the first time must receive practical instructions on the
use of a chain saw and on protection equipment from an expert.
It is advisable to begin practice cuts on wood supported by trestles.
33. All the maintenance operations on the chain saw other than those indicated in the
operating manual and maintenance instructions must be carried out by specialised
personnel. Do not attempt to carry out repairs on the chain saw yourself.
34. WARNING! Do not remove, modify, or disengage any safety device on the chain
saw. The chain brake/ hand guards are the main safety features. The chain saw does
not work if the chain brake has been disengaged.
35. Do not cut while holding the chain saw above your shoulders.
SAFETY REGULATIONS FOR NOISE AND VIBRATION
The level of noise and vibration are average values of the tool is used. The use of elements
of different size, different woods, the lack of maintenance, the pressure have a significant
influence on noise and vibration. Consequently all the preventive measures taken to eliminate
possible damage due to high noise and stress from vibration wear ear muffs, anti-vibration
gloves, made of breaks during the work, keep the tool efficiently and cutting elements.
STARTING UP
WARNING! Always use protective gloves when handling the chain.
WARNING! Before carrying out any work on the tool, switch off the internal combustion engine.
BAR AND CHAIN
1 Assembly of the bar, the chain, and the housing (Fig. A)
- Put the chain (12) in lubricating oil and leave there for some hours.
- Check that the emergency brake is released by pulling the hand guard (no. 8) toward the
front handle.
- Place the chain saw on a flat surface and remove the nut/s ( 17) and the housing (18).
Also remove the plastic spacer (29), if present, inserted in the fixing pin. This spacer
(Fig.F) must not be used!
- Using a screwdriver, turn the chain adjustment screw counter-clockwise (15) until the
end of the screw.
- Slip the bar groove (21) over the fixing pin/s (16) and pass the chain over the sprocket
(19). During this phase it is important to centre the tensioning pin (20) on the lower hole
of the bar (22).
- Insert the chain in the bar grooves making sure to respect the correct direction of the
chain (Fig. G).
- Assemble the housing (18) and, holding the nose of the bar upwards (using gloves!), fix
the nut/s (17) tightly.
WARNING! Do not use the chain saw before tensioning the chain.
2 Tensioning the chain (Fig. A)
- Loosen the bar fixing nut half a turn (17).
- Using a screwdriver, turn the chain adjustment screw clockwise (15) until the chain has
reached the correct tension.
N.B.: Checking the correct tension. The correct tension is reached when you are able to
manually lift the chain 3-4 mm to the centre of the bar (Fig.C).
- If the chain is too tense, loosen the nut/s (17) and the chain adjustment screw (15) and
push the bar leftwards in such a way as to make it slip into place.
- Repeat the adjustment taking care to tighten the screws less (15).
- When the chain has been adjusted, fix the nut/s (17) securely, always holding the nose
of the bar upwards.
- Check for the correct tension again.
- Lubricate the chain and bar rail with specific oil.
WARNING! During the first cuts, when the machine is still new, the chain will loosen
quite frequently, but this is normal during the breaking-in period of a new tool.
WARNING! Never leave the chain loose as it may come off the bar while cutting.
WARNING! If the chain is too tight, it could cause overheating and damages. It is
forbidden to use the machine without lubricating oil for the chain.
OPENING THE GUARD
Follow the instructions below to remove the guard correctly (no. 18):
1 – Pull the hand guard no. 8 towards the hand grip
2 - Remove the bar fixing nuts no. 17.
3 – Loosen (unscrew) the chain tensioning screw no. 15
4 – Extract the guard.
PREPARING THE MIXTURE
WARNING! The engine works exclusively with an oil-petrol mixture in the percentage
indicated on the specification sheet (advised to SYNTHETIC oil type JASO FC GRADE
or ISO EGC GRADE; it guarantees a better yield, a reduced smokiness and a greater
duration of the motor). If this mixture is not used irreparable damage will be caused
to the engine with immediate loss of warranty.
WARNING! Risk of fire and explosion. The fuel and its fumes are highly inflammable.
Do not pour the fuel onto hot surfaces. Work in a well ventilated area, do not smoke
and keep away from naked flames and incandescent objects. Use protective eyewear
and anti-acid heavy duty gloves. Do not swallow, do not inhale the fumes given off by
the fuel and keep it out of the reach of children. Avoid contact with the skin. In case of
contact with the eyes wash with water and seek medical advice.
WARNING! Do not use the machine in areas with a risk of explosion and/or fire, in indoor
areas or in the presence of inflammable and/or explosive liquids, gases, powders,
vapours, acids or elements. Do not use the machine in the presence of incendiary
sources such as naked flames, cigarettes, sparks, etc.
How to prepare a petrol-oil mixture
For the mixture use unleaded car petrol for (green or eurosuper) with a minimum of 90 octa-
nes and 100% synthetic oil for two-stroke engines type JASO FC GRADE or ISO EGC GRADE.
Using a container and a measurer in a petrol-resistant container mix 20cc if at 2%, 30cc if
at 3%, 40cc if at 4% of oil for every 1000 cc (1litre) of petrol. Shake the mixture well before
use. It is advisable only to prepare the quantity of mixture necessary for the task in hand.
It is advisable to add specific additives in order to prevent the mixture deteriorating over
time. The storage of the mixture for long periods without the addition of additives leads to
quick deterioration, with the consequent malfunctioning of the engine and starting problems.
Keep fuels and the oil in homologated containers, away and out of reach of children.
FILLING UP THE MACHINE (Fig. A)
IMPORTANT! Risk of fire and explosion. Refuel when the machine is switched off. Let
the machine cool before refuelling. If the fuel has splashed onto the machine or floor,
dry it up before starting the machine.
WARNING! The engine works exclusively with an oil-petrol mixture in the percentage
indicated on the specification sheet. If this mixture is not used as fuel the engine will
suffer irreparable damage with consequent immediate loss of the warranty.
WARNING! Any refuelling must be carried out with the engine switched off and the
engine ignition switch in the "stop" position (Fig.A, 25, 34C).
Before opening the petrol cap, for refuelling, place the chain saw on a flat surface with
the cap facing upwards. Open the cap (Fig.A, 14) by unscrewing it and fill up the tank
without allowing it to overflow and make sure the cap is firmly secured.
REFUELLING LUBRICATING OIL FOR THE CHAIN (Fig. A)
WARNING! Do not use old or recycled oil to fill the tank. Never use the tool without oil
as its functionality and the safety of the operator would be compromised. The chain
saw is sold with an empty tank.
Before opening the petrol cap, for refuelling, place the chain saw on a flat surface with
the cap facing upwards.
- Unscrew the oil cap (6) and fill the tank with biodegradable chain oil available in specialized
shops, hardware stores, agricultural machinery dealers, etc.
- Fill the tank to a maximum of 1 cm below the cap, being careful not to introduce dirt,
sawdust, or dust inside.
- Close the tank cap.
- WARNING! It is very important to clean the chain saw (with a brush) around the cap
before refilling.
- IMPORTANT! The oil level must be checked frequently during use to prevent the chain
remaining without lubricant. Lack of lubricant causes rapid wear of the chain and the
