WARNING!
– Avoid to keep the machine constantly running
when the chain is blocked inside the wood, since
engine can be seriously damaged.
– To prevent the bars races deteriorating rapidly, it
is essential to start and finish cutting with a
straight line, since the bar is irreparably dama-
ged if this instruction is not followed.
GENERAL MAINTENANCE
– Always keep the air holes clean on the electric
chain saw body. They tend to become clogged
with sawdust during use and this affects the effi-
ciency of cooling, causing overheating of the
motor and other fundamental parts of the electric
chain saw.
– Turn the bar periodically to use both sides so
that it wears evenly.
– It is essential that the starter grid and cylinder
fins are kept free from a build-up of sawdust as
this decreases the engines cooling capacity and
causes overheating damage to the motor as well
as to other important equipment ie. startercoil,
oil pump, etc. We recommend that this is carried
out after every use.
– Clean the guide and oil holes periodically using
the template's scraper (fig. 11)
– Deburr the race sides periodically with a flat file.
Time may cause any "burrs" to detach and
damage the bar.
– Races need to be evened with a flat file if one is
higher than the other and then smoothed with a
file and fine sand paper If races are conside-
rably worn, check that height is always greater
than the chain's transmission links so that the
latter do not touch the bottom. Replace the bar if
this should
occur.
– The pinion wears out because of the chain with
use. This creates a different perimeter of the
chain resting of the pinion compared to the initial
theoretical perimeter. Ensure that wear does not
exceed 0.5 mm (depth), otherwise the pinion
must be replaced (fig 12).
ORDINARY MAINTENANCE
CHAIN BRAKE
– Ensure the brake's efficiency frequently and
inspect belt thickness at points subject to major
friction; replace when thickness becomes less
than half of the initial thickness.
SCREW TIGHTENING
– Periodically test that all screws and nuts are
secure. Never operate the saw with any loose
parts.
EXTRA ROUTINE MAINTENANCE
– Apply to an authorized service centre for any
operations that are not of routine maintenance.
– Have your electric saw inspected frequently by
your mechanic.
– Use only original spare parts.
STORAGE
– Clean the electric chain saw with a dry cloth; do
not use aggressive cleaning fluids.
– Replace the electric chain saw in its original pac-
king box and store in a dry place. Do not store in
hot, dry boiler rooms or damp places.
CUTTING TECHNIQUES
CROSSCUTTING
– Fit the pawls in the bark in point A.
– Lever (A) and pull upwards with your right hand
so that the chain goes into the wood.
– Pivot on (B) and repeat the operation until the
trunk has been cut completely (fig. 13).
– Do not touch protruding branches with the bar
tip to prevent rebounds.
– Use the central part of the bar and never the tip
for cutting purposes.
BRANCH CUTTING
– Stand opposite the branches to be cut. Begin
from the base and proceed towards the tip
Perform the cutting operation downwards.
MAINTENANCE AND ELECTRICAL
SAFETY REPLACING THE BRUSHES
– Disconnect the electric chain saw from the
mains.
– Remove the engine cover screws and discon-
nect the two supply wires on the motor.
– Use a screwdriver ad a lever to release and
remove the two worn brushes.
– Replace the brushes with two original new ones.
POWER-SUPPLY EXTENSION
– We recommend wiring suitable for outdoor use,
with the following sections:
up to 20 metres = 1,5 sq. mm
up to 50 metres = 2,5 sq. mm
up to 100 metres = 4,0 sq. mm
ELECTRICITY-LINE GUARD
– Check that the mains voltage corresponds to
requirements.
– Use a line protected by a differential switch with
sensitivity of 10 - 30 mA (LIFESAVER).
– Check wiring frequently to ensure it is not dama-
ged.
– Check periodically the extension wire in order to
be sure it is not damaged.
– As the machine has double insulation, earthing
is not necessary.
