General safety Rules
General safety Rules
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 an well lit. Cluttered
and dark areas invite accidents.
b) Do not operate power tools in explosive
atmospheres, such as in the presence
of flammable liqui s, gases or ust.
Power tools create sparks which may ignite
the dust or fumes.
c) Keep chil ren an bystan ers 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
mo ify the plug in any way. Do not use any
a apter plugs with earthe (groun e ) power
tools. Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoi bo y contact with earthe or
groun e surfaces such as pipes,
ra iators, ranges an 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 con itions. Water entering a power
tool will increase the risk of electric shock.
) Do not abuse the cor . Never use the
cor for carrying, pulling or unplugging
the power tool. Keep cor away from
heat, oil, sharp e ges or moving parts.
Damaged or entangled cords increase the
risk of electric shock.
e) When operating a power tool out oors,
use an extension cor suitable for
out oor 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 oing an use
common sense when operating a power tool.
Do not use a power tool while you are tire or
un er the influence of rugs, alcohol or
me ication. 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) Avoi acci ental 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.
) Remove any a justing 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
an 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 an gloves away from moving
parts. Loose clothes, jewellery and long
hair can be caught in moving parts.
g) If evices are provi e for the
connection of ust extraction an
collection facilities, ensure these are
connecte an properly use . Use of
these devices can reduce dust related
hazards.
h) Use auxiliary han les supplie with the
tool. Loss of control can cause personal
injury.
4 Power tool use an 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
oes not turn it on an 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 a justments,
changing accessories, or storing power
tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
) Store i le power tools out of the reach
of chil ren an o 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 bin ing of moving
parts, breakage of parts an any other
con ition 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.

2
f) Keep cutting tools sharp an clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.
g) Use the power tool, accessories an
tool bits etc., in accor ance with these
instructions an in the manner inten e
for the particular type of power tool,
taking into account the working
con itions an the work to be
performe . Use of the power tool for
operations different from intended could
result in a hazardous situation.
5 Service
a) Have your power tool service by a qualifie
repair person using only i entical replacement
parts. This will ensure that the safety of the power
tool is maintained.

Instructions before use
Instructions before use
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
Earth
since your wall saw operates with water, its metallic
parts are connected to the earth;
make sure that the socket and possible extension
cords and multiple sockets have the earth
connection and that your electrical system is
properly connected to the earth.
arning: for your safety, it is important that
the whole system (electrical system, extension
cords, sockets etc.) is connected to the earth.
If you are not sure, ask a ualified electrician
for a check.
Extension cords
when you have to operate with your wall saw far
from an electrical socket, 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 13 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 13;
remember that the more an extension cord is long
the more the voltage drop is high and the worse is
the operation of your wall saw. Do not use
extension cords if you have to operate too far from
the electrical socket.
Preliminary operations
In order to prepare your wall saw to operate, follow these
steps. Before proceeding with preparation make sure that
the plug is disconnected from the power supply.
a) b) fix the main handle (A) in the more comfortable
position for the application as shown in figure 4.
arning: not using handles can result in loss of
control of your wall saw and serious personal
injury.
b) connect the uick hose connector (C) to a proper
water supply;
PRCD: portable residual current device
your wall saw is e uipped with a safety portable
residual current device (PRCD) assembled on the
cord. This device is shown in figure 5;
never use the wall saw without PRCD;
before starting to cut, make sure the PRCD works
properly. In order to do so, plug the wall saw in and
press the button Reset (O): a red led will light up
(P) showing that electricity is available toward the
wall saw. Than press the button Test (N) that tests
if the device works properly. When you press it the
circuit breaker inside the PRCD should cut the
power off leading the switch automatically to go to
the off position and the red led to go off;
if, when cutting, the PRCD cuts the power: stop
working, set the switch on OFF position and bring
your chain saw to an authorized service centre in
order to remove the causes of the electrical
dissipation.
ON/OFF switch
See figure 6 in order to understand how to use the switch
(figure 2 E).
Your switch is e uipped with a safety lock-off device. This
device ignite the motor only if you follow first step I and than
step II, as shown in figure 6. This prevents the wall saw from
accidentally self-starting.
Connection to a water supply
Wet cutting reduces risks connected with dust spreading.
We recommend to use your wall saw with water. If you want
to cut without water wear a proper dust mask to protect
yourself from dust. In wet cutting:
check at regular intervals that none of the water
system components are damaged. Check in
particular the valve, the uick hose connector and
the pipe;
use only the water pipe provided with your wall
saw. The water pipe includes also a valve and a
quick hose connector;
the maximum pressure of incoming water must be 4
bar;
use just clean water;
prevent water from entering the motor or other
electrical components.
