approximately 20 s before the machine is started
after switching on the main switch.
In the event of a fault or power failure, switch off
the main switch and check the cause (fuse). Before
switching on again, switch of the main switch for
60s.
Always keep the connectors clean and tight and
secure. Water or moisture in the connector may
cause serious damage to the electronics. Do
not use water jet or high pressure cleaners to
clean the converter and the machine. Max.
Water pressure 4 bar.
Status and error outputs are showed to the user via
an LED attached to the frequency converter.
Status display
If there is a status change the
green LED
on the
side of the converter flashes/shines. The number of
pulses after a longer break allows the assignation
of the status according to following chart:
Failure display
If a failure occurs the
red LED
on the side of the
converter flashes/shines. The number of pulses after a
longer break allows the assignation of the status
according to following chart:
Status display changes its status automatically. Fault
signals will be deleted when the machine is restarted (if
the cause of defect has been removed).

6.1) Follow those steps:
To perform a cut, after having carefully read the paragraphs
above and having checked grounding:
a) with unplugged chainsaw, make sure the chain is
correctly tightened;
b) plug the chaisaw in;
c) make sure the PRCD-GFI works properly according
;
d) press the green Reset button (Q) on the PRCD-GFI:
the red light (S) will light up, showing that power is
available;
e) connect the chainsaw to a power supply as shown in
paragraph
3.4) Connecti to a water supply
;
f) Turn on the valve (P) letting water in;
g) Firmly hold the saw with both hands as shown in
figure 5;
h) Make sure the chain is not in contact with anything
and then switch on the saw (O). In order to avoid
an unintentional start, the switch is equipped with
a
lock off
system. This means that you need to
follow two steps (I and II) to switch on the
chainsaw as shown in figure 3 and 4;
6.2) Cutting methods
a) Lay out the cut with a marker: the cut must be
straight;
b) To start, plunge the nose of the cutting bar
straight into material till you reach the desired
cutting depth. Keep the bar perpendicular to the
wall;
c) Rock the saw when cutting (figure 15). This
leads to leverage effect that makes cutting
easier.
d) Do not apply too much feed force. A good feed
force leads to best cutting performance, excessive
feed force leads to lower RPM and lower
performance;
e) Do not perform non-straight cuts and do not tilt side
by side the chainsaw: these would lead to motor
overload and damage bar and chains;
f)
To stop, release the switch (O);
g)
Warning
: the chain keeps running for some
seconds after the switch has been released;
h) Close the water valve (N);
6.3) Horizontal cuts
n)
You can perform either horizontal or vertical cuts.
When cutting horizontally make sure the work piece
does not press on the bar: use the product as
shown in figure 17. Do not use the product with
handle downward as shown in figure 16. When
cutting an opening such as a window perform first
horizontal cuts and then vertical ones.
