Read carefully the data written on the Technical
Data sheet that you will find in the package
together with your product.
In the following text, figures are identified by numbers,
details inside the figures by letters. Figures are depicted on
the first pages of this user manual.
Power supply
Ground
the metallic parts of your hand saw are connected
to the ground.
make sure that the socket and any extension cords
and plugs have the ground connection and that
your electrical system is properly connected to the
ground.
Warning: for your safety, it is important that
the whole system (electrical system, extension
cords, sockets etc.) is connected to the
ground. If you are not sure, ask a qualified
electrician for a check.
Extension cords
when you have to operate with your hand saw far
from an electrical outlet, you can use an extension
cord. If you use it make sure that the section of the
cord is suitable and that the cord is provided with
ground conductor;
the extension cord (made up of cable, plug and
socket) must be suitable for outdoor use. It is better
if the cord is made of rubber and it is H07RN-F;
follow the chart shown in figure 15 on this manual
for the choice of the right section of the conductors;
if you use more than one extension cord make sure
that every cable in each extension cord has a
section not lower than the value shown on the chart
in figure 15, considering the total length of the
extension cords;
remember the longer an extension cord the higher
the drop in voltage. This causes loss of rpm and
therefore cooling as well as loss of power
operating your hand saw. Don't use extension
cords if you have to operate too far from the
electrical outlet.
Preliminary operations
In order to prepare your hand saw to operate, proceed as
follows, make sure before you start that your machine is
unplugged.
a)
fasten the auxiliary handles (B) in the more
comfortable position according to the kind of cut you
are going to perform. See figure 1;
Warning: not using auxiliary and main handles
can result in loss of control of your hand saw
and serious personal injury.
b)
connect the quick hose connector (figure 1 D) to a
proper water supply, keep the valve C close till you
start to cut;

PRCD-GFI:
portable
device or GFI: Ground Fault Interrupter
your hand saw is equipped with a safety portable
residual current device (PRCD or GFI) assembled
on the cord. This device is shown in figure 5;
never use hand saw without PRCD-GFI;
before starting to cut make sure the PRCD-GFI
works properly. In order to do so, plug the hand
saw in and press the green button Reset (O): a red
led will light up (P) showing that electricity is
available to the hand saw. Than press the blue
button Test (N) that tests if the device works
properly. When you press it, the circuit breaker
inside the PRCD-GFI should cut the power off
leading the switch automatically to go to the off
position and the red led to go off;
if, during operation, the PRCD-GFI cuts the power:
stop working, put the main switch of you hand saw
on the OFF position and bring your hand saw to an
authorized service centre in order to remove the
causes of the electrical malfunction.
ON/OFF switch
See figure 6 in order to understand how to use the switch
(figure 2 E).
Your switch is equipped with a safety lock device. With this
device you can switch on the motor only if you follow first
step I and than step II, as shown in figure 6. This prevents
the hand saw from starting accidentally.
Caution: after switching off, the machine will
not be idle immediately.
Connection to a water supply
Wet
cutting
reduces
environment. We recommend operating your hand saw with
water. Make sure the blade is suitable for wet cutting. If you
want to cut without water wear a proper dust mask to protect
yourself from dust inhalation.
While wet cutting:
use only the water hose (figure 1) provided with
your hand saw. The water hose includes also a
valve (C) and a quick hose connector (D);
the maximum pressure of incoming water cannot
exceed 4 bar;
use always clean water;
control the flow of water by turning the valve (C). A
small amount of water is enough to suppress saw
dust;
prevent water from entering the motor or other
electrical components;
check at regular intervals that none of the water
system components are damaged. Check in
particular the valve (C), the quick hose connector
(D) and the pipe.
Setting cutting depth
Refer to figure 13, proceed as follows:
unlock the roller guide R by loosening the S knob;
than turn the roller guide to select the cutting depth
(13/A);
to lock the guide, tighten the S knob, making sure
that the guide is engaged as shown in figure 13/B;
For applications where the guide is not needed, fasten the
guide fully turned toward the switch.
