General working instructions

WARNING! This section describes basic
!
safety directions for using a wall saw. This
information is never a substitute for
professional skills and experience. If you get
into a situation where you feel unsafe, stop
and seek expert advice. Contact your dealer,
service agent or an experienced user. Do not
attempt any task that you feel unsure of!
• 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 hydraulic hoses
are in full working order.
• Keep the hydraulic hoses and couplings free from dirt.
• Do not misuse hoses.
• Do not use hoses that are distorted, worn or damaged.
• Make sure that all hoses and electrical cables are
connected to the machine correctly before you start the
machine.
• Check that the hoses are connected correctly to the
machine and that the hydraulic couplings lock as intended
before pressurising the hydraulic system. The couplings
are locked by turning the outer sleeve on the female
coupling so that the slot moves away from the ball.
The pressure hoses in the system must always be
connected to the tool's intake. The return hoses in the
system must always go to the tool's outlet. Confusing the
connections can cause the tool to work in reverse, which
can result in personal injury.
• Never use the hydraulic hoses to lift the machine.
• Check the machine, couplings and hydraulic hoses daily
for leakage. A rupture or leak can cause a "hydraulic fluid
injection" in the body or result in other serious physical
injury.
• Never disconnect the hydraulic hoses without first shutting
off and disconnecting the hydraulic unit and ensuring the
motors have stopped completely.
• If despite all precautions an emergency situation should
arise, press the red emergency stop button on the top of
the unit or press the green start/stop button on the remote
control.
• Do not exceed the specified hydraulic fluid flow or
pressure for the tool being used. Excessive pressure or
flow can result in rupturing.
• Do not check for leakage with your hands. Contact with
the leak can result in serious personal injury caused by
the high pressure in the hydraulic system.
• Check that power cables and the Canbus cable are not
damaged or can be damaged while working.

SAFETY INSTRUCTIONS
• Working close to power lines:
Hoses that are marked and approved as electrically non
conductive must be used when using hydraulic tools on or
in the vicinity of electrical cables. The use of other types
of hoses can result in serious physical injury or even
death.
When replacing hoses, hoses marked non-conducting
dielectric" must be used. The hoses must be regularly
checked for their electrical conductive insulation in
accordance with special instructions.
• Working close to gas conduits:
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.
• Run the hydraulic system until it reaches its operation
temperature of 30°C before starting to saw, to reduce
return pressure and other wear.
• 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.
• People that need to be in close proximity of the machine
must wear hearing protection as the sound level when
cutting exceeds 85 dB(A).
• The safety distance is 4 meters (15 ft) from the machine.
• 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.
