General Working Instructions - Husqvarna PP 325 E Operator's Manual

General working instructions

WARNING! This section describes basic
!
safety directions for using the machine.
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 oil 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 an emergency situation should arise anyway, push
the red emergency stop button on the power pack.
• Do not exceed the specified hydraulic oil 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 the power supply and the power cables and
make sure that they are not damaged.
• Working close to power lines:
SAFETY INSTRUCTIONS
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 motor
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).
• 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 imply the risk of pinch injuries or other
injuries.
