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 the blade guard is not damaged and that it has
been fitted correctly.
• Never use blades other than original blades designed for
the machine. Check with your Husqvarna dealer to see
which blades are best suited for your usage.
• Never use a damaged or worn blade.
• Never mount or dismount the blade or blade guard without
first switching off the hydraulic unit and disconnecting the
hydraulic hoses running to the saw unit.
• Never cut without using the blade guard.
• Check that the blade is not in contact with anything when
the machine is started.
• Remain at a distance from the blade when the engine is
running.
• Water cooling must always be used. This cools the blades
and increases their life and prevents dust build-up.
• 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.
• 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.
• Never use the hydraulic hoses to lift the saw.
• 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.
• Do not exceed the specified hydraulic fluid flow or
pressure for the tool being used. Excessive pressure or
flow can result in rupturing.
• 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.
SAFETY INSTRUCTIONS
• Run the hydraulic system until it reaches its operation
temperature of 30 ºC before starting to saw, to reduce
return pressure and other wear.
• Clearly mark out all cuts to be made before you start
sawing, plan these so they can be carried out without
danger to persons or the machine.
• Firmly secure or anchor concrete blocks before cutting.
The heavy weight of cut material can cause extensive
damage if it is not moved under controlled conditions.
• Always check the back of the wall where the blade comes
out when cutting through. Secure, cordon off and make
sure that no people can be injured or materials damaged.
• 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.
• Never saw in such a way that you cannot easily reach the
emergency stop on the hydraulic unit or on the remote
control. See hydraulic unit manual.
• 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).
• Make sure that no people or animals come closer than 4
m (15 ft) when the machine is running.
• 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.
WARNING! Never use a blade for any other
!
materials than that it was intended for.
Operating saw blades at rotational speeds
greater than those recommended by the
manufacturer can cause blade damage and
possibly subsequent injury. See the
Technical data section.
