Your CARDI hand-held hand saw (or hand saw) is a power tool designed to make straight
cuts in stone-like materials (ex. reinforced concrete, bricks, masonry, natural stone) using
laser-welded diamond blades or metal using abrasive blades.
Warning: do NOT use circular saw blades or other kind of blades not suitable for
this product. Failure to follow this warning may result in serious personal injury
(fig. 8 and 9).
G
Ge en ne er ra al l s sa af fe et ty y r ru ul le es s
WARNING! Read all instructions. Failure to follow all
instructions listed below may result in electric shock, fire
and/or serious injury. The term "power tool" in all of the
warnings listed below refers to your mains operated (corded)
power tool or battery operated (cordless) powertool.
SAVE THESE INSTRUCTIONS
1) Work area
a) Keep working area clean and well lit. Cluttered
and dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce
risk of electric shock.
b) Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired or
under the influence of drugs, alcohol or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
b) Use safety equipments: always wear eye
protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will
reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is
in the off position before plugging in. Carrying
power tools with your finger on the switch or
plugging in power tools that have the switch on
invites accidents.
d) Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may
result in personal injury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better control of
the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery
and long hair can be caught in moving parts.
g) If devices are provided for the connection of
dust extraction and collection facilities, ensure
these are connected and properly used. Use of
these devices can reduce dust related hazards.
h) Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
4) Power tool use and care
a) Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
b) Do not use the power tool if the switch does not
turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tools operation. lf damaged, have the
power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to binf and are easier to control.
g) Use the power tool, accessories and tool bits
etc., in accordance with these instructions and
in the manner intended for the particular type of
power tool, taking into account the working
conditions and the work to be performed. Use
of the power tool for operations different from
intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

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;
c) select the cutting depth: see paragraph Setting
cutting depth.
PRCD-GFI: portable residual current
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 risks connected with dusty
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.

English 3
Flush cutting accessory
To mount the flush cutting accessory refer to figure 14.
Warning: always use blades with countersunk
holes suitable for the flange (this kind of blades
are available as accessory).
Warning: do not use abrasive blades when flush
cutting.
Proceed as follows:
remove the guard by loosening the 5 screws (14/A);
loosen the blade-tightening screw and remove the
flange and the blade (14/B);
remove the internal flange by unscrewing the 3
screws using the provided Allen key (14/C);
position the flange provided together with the flush
cutting accessory as shown in figure (14/D);
position a suitable blade and fasten it by tightening
all 4 (or 6) screws (14/E);
position and fasten the flush cutting guard by
tightening the 5 screws (14/F).
Checks and precautions to avoid
structural damages and damages to
objects
Before starting any cutting activity, talk with the construction
manager or the planner in order to make sure that the cut
doesn’t:
make any damage to the structure of the building
and doesn’t change the structural characteristics of
the construction;
damage any water or gas pipeline or any electrical
circuits.
Blade choice
Your Cardi hand saw has been designed to cut building
materials such as concrete, reinforced concrete, bricks,
masonry, natural stone, tiles etc, using laser welded
diamond blades (figure 10 and 11) or metal using abrasive
blades.
Warning: Do NOT use circular saw blades or
other kind of blades not laser-welded. Failure to
follow this warning may result in serious personal
injury. See figure 10 and 11.
Ask your dealer about the best blade for your application.
The blade must have:
a) maximum diameter: 400 mm (16 inches)
b) arbor hole diameter 25,4 mm (1 inch). You can use
a blade with a 30 mm arbor hole using a proper
distance piece;
c) width between 2 and 3 mm (0.08 – 0.12 inch);
d) maximum rotating speed (provided by the blade
manufacturer), higher than the maximum rotating
speed of the arbor of your hand saw, shown on the
data plate (see figure 14 I).
Use blades with diameter, arbor hole and rotating speed
compatible with your specific hand saw model. Use of
blades with inappropriate dimensions can result in
misalignment, vibrations, irregular rotation and loss of
control causing serious injury.
Check the blade before use. Do not use damaged blades.
Blade mounting and replacement
Before mounting or replacing the blade (figure 1 H), make
sure the hand saw is unplugged. Refer to the following
directions depending on the kind of blade you are using:
Diamond blades (no internal flange + small flange)
For blade mounting and replacement refer to figure 10.
Proceed as follows:
loosen and remove the blade-tightening screw
(10/A) using the key provided;
remove the flange and the blade (if already
mounted) (10/B);
using the Allen key provided loosen the screws and
remove the internal flange (10/C) (if not already
removed);
position the diamond blade (10/D), making sure the
arrow on the blade meets the direction of rotation
on the guard;
mount the small flange as shown in figure (10/E).
fasten the blade by tightening the blade tightening
screw (10/F);
Abrasive blades (internal flange + big flange)
For blade mounting and replacement refer to figure 11.
Proceed as follows:
loosen and remove the blade-tightening screw
(11/A) using the key provided;
remove the flange and the blade (if already
mounted) (11/B);
make sure the internal flange is mounted (11/C). If
not, assemble the flange and fasten it by tightening
the screws. Use the Allen key provided;
position the abrasive blade (11/D);
mount the big flange (11/E), make sure the flange
is the right one;
position and tighten the blade-tightening screw
(11/F);
Warning: for your safety, when using abrasive
blades, make sure the internal flange is mounted
to the machine and make sure that the external
flange is the big one.
Fastening the work piece and size of the
work piece
if the work object is a block and not part of a
structure, fasten it in order to prevent its movement;
prevent the work piece from shifting, moving or
falling when you are cutting.
Environmental conditions
do not expose the hand saw to rain, ice or snow;
prevent water or any other liquid from coming into
contact with the electrical parts of your machine;
do not use the hand saw in explosive atmospheres,
for instance flammable liquids, gas or dust. The
electric hand saw produces sparks which can ignite
fumes, dust or smoke.

After having followed the instructions given in the previous
Preliminary operations paragraph, proceed as follows in
order to perform the cut.
Warning: do not touch any moving parts of your
hand saw, in particular the blade, when operating.
turn your hand saw on and move closer to the
material to be cut. When the blade touches the
surface, push the hand saw toward the material and
let the blade going inside the material till you reach
the desired cutting depth. Than move the hand saw
parallel to the surface in order to perform the cut;
your hand saw is intended to perform straight cuts
only;
avoid friction between the blade-side and the work
piece: move the hand saw just forward avoiding
side movement of the blade. The friction can
overload the motor;
Warning: When working, make sure you stand
safely. Always hold your machine with both
hands. The blade can jam, so be always ready
to face this event: the electronic of your
machine allows you to move the machine out,
to free the blade and to continue cutting.
use the handles and hold your hand saw firmly with
both hands (see figure 3 and 4) and be ready to
resist to possible saw’s movements;
cutting materials containing wood, cork, rubber,
foam polystyrene can result in problems moving
forward the machine. If you have this kind of
problems, stop cutting and remove all materials
listed before and proceed with cutting operations. If
you cannot remove these materials, stop cutting
and cut in another position;
in case the electric power goes off, position the
switch in the off position to prevent the machine
from accidentally self starting;
when you complete the cut, switch off your hand
saw and wait till the blade comes to a complete
stop. Then pull the hand saw out of the cut and
close the water valve (C). Watch out! The blade
and the cutting area can be very hot and cause
severe burns.
Electronic devices
Your hand saw is equipped with a CARDI multifunction
electronic device that includes a soft-start and an electronic
clutch:
the soft-start allows the motor to start gradually,
reducing peak current that occurs when you switch
the motor on, helps you when you begin cutting,
allowing gradual blade rotation and avoiding jerks
at the operator’s arm. It allows you to use your
hand saw connected to household electrical outlet.
the electronic clutch cuts off power to the motor in
case of excessive overload, increasing the operator
safety and preventing damage to the motor. When
the overload is over, the device gives back power to
the motor that begins working again;
if the electronic clutch operates frequently means
that the hand saw is not used properly. Possible
causes can be a not suitable forward speed, an
excessive friction between the blade-side and the
material, excessive cutting depth. In these cases,
stop cutting and let the machine turn with no load
for some seconds, helping the motor cool down.
