General safety regulations
To reduce the risk of personal injuries, any-
one who uses, installs, repairs, or services
this tool, replaces its parts or works in its
vicinity, must have read and understood
these instructions.
Our objective is to manufacture tools that
enhance working safety and efficiency. The
most important safety factor for this and
any other tool is ITS USER. Your diligence
and judgement are the best protection
against accidents and injuries. Because
all possible risk factors cannot be treated
in this manual, only the most important
are mentioned. Only professionally trained
users may install, adjust, or use this com-
pressed air tool. This tool or its parts may
not be altered in any way. Do not use this
tool if it has been damaged. If the rating
plate displaying the nominal speed or
operational pressure, or stickers warning
of dangers, are no longer legible or have
become detached, they must be replaced
immediately.
Consult the following sources for further
occupational safety-related information:
• Other guidelines and bulletins provided
with the tool.
• Your employer, professional association,
and/or labor union
• “Safety Code for Portable Air Tools”,
(ANSI B186.1), at the time of publication
available from the Global Engineering
Documents organization at:
http://global.ihs.com/ or telephone
number 1 800 854 7179. If procuring
the ANSI standards is difficult, contact
the ANSI organization at:

Dangers related to the compressed air
feed and couplings
• Compressed air can cause serious injuries.
Always check the condition of the cou-
plings, compressor, and hoses before use.
• Always turn off the air feed, release the
pressure from the pipes and/or hoses,
and detach the tool from the air feed
source when it is not being used, repairs
are being made, or parts are being
changed. After the shutoff, the hose is
emptied by pushing the START button
(Picture A1) to cut off the compressed
air flow. The machine will run for a few
seconds, after which the hose will be
emptied of air. Watch out for the spinning
blade and make sure that nothing has
been caught in the saw’s blade or other
parts. Open the coupling only when you
are sure that the hose is unpressurized.
• Never point a compressed air hose at
yourself or anyone else. Always make
sure that the compressed air cannot
send objects or materials flying
dangerously towards yourself or others.
• Compressed air hoses waving around
uncontrollably are extremely dangerous
and can cause serious injuries to people,
as well as damage to equipment,
materials, and the surroundings. Always
check that the hoses and couplings are
intact and tightly closed. Make sure that
couplings are always secured with a
durable safety wire. Check the safety
wire’s condition and durability before use.
• If you use a quick coupling, always make
sure that the couplings are intact. Always
use a safety wire loop to prevent the
hoses’ uncontrolled loosening if the
coupling breaks. Check the use of the
couplings with the applicable safety
instructions provided by the manufacturer.
Read the installation instructions carefully.
• If general purpose threaded couplings are
used, locking pins must also be installed.
• The air pressure must not exceed 6.3
bar (90 PSI) or the pressure specified on
the tool’s rating plate. Exceeding the
pressure recommendation can result in
the machine’s breakage or a hazardous
situation.
• Check the hose’s condition before
installation. A broken or worn out hose
may cause a hazardous situation.
Danger of catching
• Stay clear of spinning grinding disks or
blades. Note that the blade will continue
to spin after the closing of the START valve
and it may continue spinning for several
seconds.
• Entangled clothes, gloves, jewelry, ties,
scarfs or long hair in the tool or its acces-
sories can cause choking, scalp injuries,
and/or deep wounds.
Never open the blade guard (Picture A5) if
you are not sure if the blade or grinding disk
has stopped spinning.
Danger caused by flying objects
• The machining of steel and other materials
can quickly generate flying debris. Even
small objects can injure the eyes and
cause blindness.
• Always use impact-resistant protective
goggles and a safety mask when operating
the tool, working nearby in repair and
servicing areas, or changing parts.
• Make sure that other users in the same
area are also wearing protective goggles
and safety masks.
• Make sure that the pipe to be cut is firmly
supported. A weakly or improperly supported
pipe may cause a hazardous situation.
• Make sure that the sparks generated by
the machine can never, under any circum-
stances, come into contact with flammable
and/or potentially explosive materials or
liquids.
• Make sure that sparks or shavings pose
no danger to other persons at the job site.
Equipment-related risk factors
• Before changing a blade, always shut off
the air feed, release the air pressure from
the hose and detach the tool from the air
feed source.
• Use only the recommended sizes and
types of blades.
• Never use a damaged blade. Always check
the blade’s condition before use.
• Check the blade’s attachment before use.
For more detailed instructions, see the
Changing Blades
section, page 18.
Operational risks
• Users and servicers must be able to
physically handle the tool’s size, weight,
and power.
Safety information
• Hold the tool properly: be ready to react
to any abnormal or sudden movement –
keep both hands ready.
• Never use the tool unless the blade is
aligned with the material to be cut.
• The Exact 360 AIR is designed to be used
with a blade guard that must always be in
place to provide protection from shavings
and other debris. Never operate a pipe
saw if the blade guard is improperly
attached.
• Never move the machine while the motor
is running or the blade is rotating.
• Do not use the tool if you are tired or your
alertness has become impaired for health
reasons.
• Do not start working if your foothold or
balance is unsteady. Falling while holding
a saw can cause a hazardous situation.
