MOUNTING THE CHAIN BAR
– Loosen the nuts, remove the washer and the
first plate (fig 1).
– Insert the bar A in the stud bolts and push
towards the pinion (fig. 2).
– Fit the chain onto the pinion with teeth facing
forwards (towards ti tip of the bar). Fit the trans-
mission links into the pinion teeth (fig. 3).
– Make the chain fit perfectly against the bar (fig.
4).
– Replace the cover, do not tighten the nut and
with a screwdriver adjust chain tension by
means of the chain tension screw (fig. 5).
– Tighten the bar nut using the spanner provided
(fig. 6).
– Then tighten the chain tension screw with a
screwdriver until the chain fits firmly around the
bar.
– Lift the chain bar and tighten nuts with a span-
ner.
WARNING. If the chain tensioner pin does not fit
in the hole on the bar correctly it may cause irre-
parable damage when the clutch guard nuts are
tightened.
– To check for correct adjustment of chain tension
try pulling the chain away from the bar. It should
not be possibletofullyremovethetransmission
linksfromthe bar The chain should slide
smoothly when pulled. If this is not the case,
please re-adjust.
– The chain will stretch after a few minutes of
work. Adjust chain again as described above .
REFUELLING
– Disconnect the electric chain saw from the
mains.
– Remove oil cap and use a fonnel to fit the tank
with lubricating oil. Replace the cap and tighten
well (fig. 7).
– Lubrication is activatedonly when the machine is
working.
– Chech the oil level periodically, through the side
observation glass (fig. 8).
– If the chain is not being lubricated correctly,
ensure that sawdust has not obstructed the oil-
way. The oilway is located in the main body of
the saw undemeath Plate A (see fig. 2).
– Remove the side cover and Plate A (fig. 1 and 2)
and clear any sawdust from around the chain
and oilway.
– Use good quality ecological chain oil to ensure
long life for the moving parts. Do not use reco-
vered or used oil or oil containing impurities.
– If it is necessary to use single grade oil, ensure
that it is suitable for external ambient temperatu-

START UP
– Remove the bar cover.
– Release the chain brake.
– The main on/off switch (see fig. 9), must always
be released before pulling back the front
guard/chain brake.
– Hold the electric chain saw by its grip with both
hands.
– Press the start-lock safety button and then the
acceleration lever (fig. 9).
– Release the acceleration lever to stop the elec-
tric chain saw.
WARNING:
Hold the electric chain saw with both hands until
the chain is completely still.
CHAIN SHARPENING
AND MAINTENANCE
– The chain requires sharpening when the electric
saw does not cut appropriately; this operation is
performed as follows:
– Extend the chain.
– Fix the bar in a vice so that the chain can slide
(fig 10).
– Fix the file in a file holder and place it over the
tooth at 35¡ (see notch on the file holder) (fig.
10).
– File forward only until all the worn part of the
tooth has been eliminated.
– Count the file movements made on the first tooth
and do the same on all the others. both right and
left.
– After some sharpenings the delimiting device
will exceed the template; file the exceeding part
by means of a flate file Round off the depth deli-
miting device (fig. 10)
– Ensure that the chain is replaced before stret-
ching to a max 5mm of its original length or if
there is too much play on the rivets.
– "Deep" filing should be performed with an elec-
tric file We advise to apply to a service centre to
perform this operation.
– Ensure that the chain slides smoothly over the
bar whe pulled with hands (periodically sharpen
chain and check chain tension)
– Bars with sprockets need frequent greasing
which can be performed as follows:
a) Fill the specific syringe with grease for bea-
rings
b) Each time the saw is used grease through the
hole provided near the bar tip until the grea-
se penetrates onto the tip.
– There is no syringe when the bar has no "grea-
sing hole".
