alcohol, or if you are taking medication that could affect
your vision, your judgement or your co-ordination.
• Wear personal protective equipment. See instructions
under the heading Personal protective equipment.
• Never carry the machine by holding the cable and never
pull the plug by pulling the cable.
• Keep all cables away of water, oil and sharp edges. Make
sure the cable is not pinched in doors, fences or the like.
It can cause the object to become live.
• Check that the cables are intact and in good condition.
• Never use the machine if any cable is damaged, but hand
it in to an authorized service workshop for repair.
• The machine should be connected to an earthed outlet
socket.
• Check that the mains voltage corresponds with that stated
on the rating plate on the machine.
• Keep all parts in good working order and ensure that all
fixtures are properly tightened.
• Never use a machine that is faulty. Carry out the checks,
maintenance and service instructions described in this
manual. Some maintenance and service measures must
be carried out by trained and qualified specialists. See
instructions under the heading Maintenance.
• Do not modify safety equipment. Check regularly that they
function as they should.The machine must not be run with
defective or disassembled safety equipment.
• Never allow anyone else to use the machine without first
ensuring that they have understood the contents of the
operator’s manual.
• People and animals can distract you causing you to lose
control of the machine. For this reason, always remain
concentrated and focused on the task.
• Be careful as clothing, long hair, and jewellery can get
caught in moving parts.
• Observe care when lifting. You are handling heavy parts,
which implies the risk of pinch injuries or other injuries.
Transport and storage
• Always switch of the power unit and pull out the electric
cable before moving the equipment.
• Store the equipment in a lockable area so that it is out of
reach of children and unauthorised persons.
• If there is a risk of freezing, the machine must be drained
of any remaining water coolant.
• Use the cases provided to store the equipment.
General working instructions
• All operators shall be trained in the use of the machine.
The owner is responsible for ensuring that the operators
receive training.
• Check that all couplings, connections and cables are
intact and free from dirt.
• Check that all cables and the water supply are correctly
connected to the machine before starting it.
• Never pull out the power cable without first switching off
the power unit and waiting for the engine to come to a
complete halt.
• If an emergency situation should arise anyway, push the
red emergency stop button on the power unit or the stop
button on the remote control.
• Always check and mark out where gas pipes are routed.
Cutting close to gas pipes always entails danger. Make
sure that sparks are not caused when cutting in view of
the risk of explosion. Remain concentrated and focused
on the task. Carelessness can result in serious personal
injury or death.
• Make sure that no pipes or electrical cables are routed in
the area to be cut.
• Check that electrical cables within the working area are
not live.
• Never leave the machine unsupervised with the engine
running.
• Always saw in a manner that permits easy access to the
emergency stop.
• Make sure that there is always another person close at
hand when you use the machines, so that you can call for
help if an accident should occur.
• Do not use the machine in bad weather, such as dense
fog, rain, strong wind, intense cold, etc. Working in bad
weather is tiring and can lead to dangerous conditions,
e.g. slippery surfaces.
• Ensure that the working area is sufficiently illuminated to
create a safe working environment.
• Always ensure you have a safe and stable working
position.
• Observe care when lifting. You are handling heavy parts,
which implies the risk of pinch injuries or other injuries.

ASSEMBLY
Assembling/Installing equipment
When the machine has been transported to a suitable site, it
should be connected:
• Turn the main switch to the "0"-position.
• Connect the incoming power cable (380-480 V, 32 A
European connector). Power units equipped with a single
phase socket (230 V) must also have a neutral wire.
To be able to use full power output, the power unit must be
connected to a 32 A fuse. With a 16 A or 25 A fuse the
power output is lower so as not to overload the fuse. This
is selected when starting up the power unit.
• Connect the water hose to the incoming water connector.
The power unit is equipped with an electric water valve,
which is closed when the power pack is activated. When
the power pack is without electricity, the valve is open to
be able to drain water coolant if there is a risk of freezing.
• Connect the supplied power lead and water hose from the
power unit to the saw unit.
• Connect the remote control using the supplied Canbus
cable. Tighten the cable connector screws by hand.
