Start-up:
grip both handles firmly, release the chain
brake lever whilst ensuring hand is still on front
handle, press and maintain the switch block
pressed in, then press the switch
point the switch block can be released).
ATTENTION!
Insufficient lubrication will provoke
chain breaking and can cause serious and even fatal
injury.
Bar and chain lubrication is performed by an
automatic pump.
Refer to "Maintenance & Storage" for indications on
ensuring that the chain oil is sufficiently distributed.
Choice of chain oil
Always use new oil only (special type for chains) with
adequate viscosity: the oil must adhere well and
guarantee good running properties in both winter and
summer. If chain oil is not available, EP 90
transmission oil can be used.
Before performing any maintenance or cleaning,
remove the plug from the mains.
ATTENTION!
In cases where work environments are
particularly dirty or dusty, the operations described
must be performed more frequently than mentioned
in the instructions.
Before each use
Check that the chain oil pump functions correctly:
direct the bar towards a clear surface at a distance of
about 20 centimetres; after the machine has run for
about a minute, the surface should show clear traces
(fig.1)
of oil
.
Check that excessive strength is not needed for
activating and deactivating the chain brake. Also
check that it is not activated too easily and that it is
not blocked. Then check chain brake function as
follows: release the chain brake, grip the machine
correctly and start up the machine, activate the chain
brake by pushing the front hand guard forward with
the left wrist or arm but without removing the hand
(fig.2)
from the handle
correctly, the chain should be stopped immediately.
Check that the chain is sharpened correctly, in good
working condition and that the tension is correct. If
the chain is irregularly worn, or if the cutting teeth are
only 3 mm long, the chain must be replaced
Clean the air vents regularly to prevent motor
(fig 4)
overheating
.
Check that the switch and switch block function
correctly (to be performed with the chain brake
released): press the switch and the switch block and
ensure that they return to idle position as soon as
they are released; check that it is impossible to press
the switch without activating the switch block.
Check that the chain catcher and the right hand
guard are in correct condition without any visible
faults such as damaged material.
Every 2-3 hours of use
Check the bar condition, if necessary clean the
(fig.5)
lubrication holes
carefully; If the groove is worn or shows signs of
deep notching, it must be replaced. Clean the drive
sprocket regularly and check that it has not been
subject to excess wear

Stopping:
switch is released. In the case where the machine
(fig E1)
does not stop, activate the chain brake, disconnect
the cable from the main line socket and take the
machine to the Authorised Service Centre.
Never use waste oil because this is this harmful to
health, the machine and the environment. Make sure
that the oil is suitable for the temperature of the
environment where the tool will be used: For
temperatures under 0°C certain oils become thicker,
overloading the pump and causing damage. Contact
your Authorised Service Centre for advice on oil
choice.
Filling oil tank
Unscrew the oil tank cap, and fill the tank taking care
not to spill any oil (if this occurs clean the machine
carefully) and then screw the cap back on tightly.
Chain sharpening (When necessary)
If the chain does not cut correctly, or requires hard
bar pressure against the wood, and if the sawdust is
very fine, this is a sign that it is not sharpened
correctly. If the cutting action produces no sawdust,
this means the cutting edge has been worn
completely and the chain is pulverising the wood
during cutting. A well-sharpened chain crosses
through the wood without effort or pressure and
produces large long wood shavings.
The cutting side of the chain is composed of the
cutting link
cutting limit gauge
these determines the cutting depth; a file guide and a
4mm diameter round file are needed to obtain good
sharpening results; Follow the instructions below:
Once the chain has been mounted and the tension is
correctly adjusted, and the chain brake is activated,
position the file guide perpendicular to the bar as
shown in the illustration

.
diameter will increase the risk of kickback.) To obtain
higher precision on side angles, it is advisable to
position the file so that it exceeds the upper cutter by
about 0.5 mm. File all the teeth on one side first,
then turn the machine over and repeat the operation.
Make sure that after sharpening operations, all teeth
are the same length and that the height of the depth
gauge is 0.6 mm lower than the upper cutter: check
the height using a proper template and file (with a flat
file) all protruding parts, rounding off the front part of
the depth gauge

Every 30 hours use.
Take the machine to the Authorised Service Centre

for general revision and control check on brake
components.
