on the pin (16).
- Pull the bar to the right to slightly tension the chain.
- Assemble the housing (18), correctly inserting the reference pins.
- Fix the cover by turning the handwheel (17) up to the limit switch.
The handwheel should automatically tension the chain
WARNING! Do not use the machine before tensioning the chain.
WARNING! The chain may become loose during use. Follow the
instructions in the next paragraph.
2 Tensioning the chain (Fig.C)
- Loosen the handwheel (17) by a few turns and fix it again, the chain
should tighten correctly.
- If the chain is too tight, turn the handwheel (17) and repeat the
adjustment.
WARNING! The chain tension should be checked every time you
start work, after the first cuts and regularly every 10 minutes.
WARNING! During the first cuts, when the machine is still new the
chain may come loose. This is normal behavior.
WARNING! Never leave the chain loose because it can come out
of the bar while you are cutting.
WARNING! The chain that is too tight or too loose can wear out
abnormally and wear out the bar.
3. FILLING THE TANK AND LUBRICATION OF THE CHAIN
IMPORTANT! Do not use old or recycled oil to fill the tank. Use
biocompatible and biodegradable chain lubrication oil.
Introduction:
The chain saw is sold with an empty tank.
- Do not use the chain saw without oil or with an oil level under
the minimum as it will compromise the proper functioning of the
equipment and operator safety.
- Unscrew the oil cap (Fig. A nr. 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 2 cm below the cap, being careful not
to introduce dirt, sawdust, or dust inside.
- IMPORTANT! It is very important to keep the chain saw clean (with
a brush) around the cap before refilling.
- IMPORTANT! The oil level must be controlled frequently during
running because the chain must always be lubricated. If the chain
saw runs without oil or with oil below the minimum level, the chain
and the bar will wear out quickly and tool’s lifespan will be reduced.
Check the oil level frequently through the inspection window (nr.9)
to ascertain that it does not fall below the minimum.
- IMPORTANT! One fill-up of oil may last from 10 to 30 minutes accor-
ding to the type of wood being cut, the environmental temperature,
the oil density, and the usage of the chain saw.

OPERATING INSTRUCTIONS
1. Starting the electric chain saw
2. Stopping the electric chain saw
3. Controlling that the automatic oiler functions correctly
4. Controlling that the chain brake functions correctly.
5. Controlling the stoppage of the chain when the start lever is
released.
These operations are described individually below:
1. Starting the electric chain saw
- Check that the chain brake is deactivated, pulling back (towards the
motor) the front hand guard (nr. 8).
- Hold the saw firmly with both hands when running, with your right
hand on the rear hand grip (nr. 2 Fig. A) and the left hand on the
front hand grip (nr. 7 Fig. A).
- Turn on the chain saw by pushing the release button (nr. 5) first and
then pulling the start lever (nr. 4).
Note: once the chain saw is running, it is not necessary to hold
down the release button.
The release button (nr. 5) is a safety device that prevents accidental
starts.
2. Stopping the electric chain saw
- The chain saw stops automatically when the start lever (nr. 4) is
released.
3. Controlling that the automatic oiler functions correctly
Introduction:
- Check that the tank is full of oil.
- Turn on the chain saw over a sheet of cardboard holding the blade
about 4 cm away.
- If an oil stain forms on the cardboard within a minute, the lubrication
device is working correctly. If there is no oil on the cardboard, read
the “Troubleshooting” paragraph.
4. Check the emergency brake lever (hand guard)
Introduction:
The chain brake is a safety device that is activated by exerting pressure
against the front hand guard (nr.8 Fig. A) when, in case of a kickback,
the operator’s hand hits the lever. When the chain brake is activated,
the movement of the chain is arrested within 0.15 seconds.
The purpose of the chain brake is to reduce danger in case of kickback.
Before using the chain saw, you must test the chain brake as follows:
- Check that the chain brake is deactivated, pulling the front hand
guard (nr. 8) back towards the motor.
- Position the chain saw on a solid flat surface that has been cleared
of all objects.
- Connect the chain saw to the power supply, take it in both hands,
and turn it on.
- While the chain saw is functioning, activate the chain brake by
pushing your left hand against the hand guard (nr.8).
- The chain should stop instantly.
N.B. Release the start lever immediately.
- IMPORTANT! If the chain does not stop when the brake is activated,
have the chain saw checked at an authorised customer service
centre.Do not use the chain saw if the chain brake does not function
properly!
SHARPENING THE CHAIN
- Bring the chain to a specialized workshop for maintenance.
- IMPORTANT! If the chain is not sharpened regularly, the risk of
kickback is increased.

1. Advice for those using the chain saw for the first time
Those who are using the chain saw for the first time should receive
practical instructions concerning its use and gear by an expert ope-
rator. A beginner should first practice by cutting wood on a trestle
or other support.
