Manoeuvring
General
• If several machines are used at the same workplace
there is a risk of mixing up the remote controls.
Switch on the current to the remote control and the
machine. Press the horn to see which machine is
connected to the remote control. The machine will
beep and flash three times. Do not activate the remote
control before you have ensured that the correct
machine is being operated.
• Wait until the remote control has been turned off and
the motor has stopped before you enter into the
machine's risk area.
• Never leave the machine unsupervised with the motor
running.
• The machine can overturn during work. During
operation the machine must be positioned as level as
possible and the outriggers must be fully extended.
• In some cases it can be difficult to determine which
end of the machine is the front and which is the rear.
Look at the direction markings on the sides of the
machine's tracks to avoid incorrect operation.
• When work is finished, operate the arm to rest against
the ground before turning off the machine.
Outriggers
• When the outriggers are folded, the arm must be
retracted to minimize the risk of the machine
overturning.
• The machine's outriggers can leave the ground,
especially when working with a hydraulic hammer or
bucket. The higher the machine rises the greater the
load the rest of the support mechanism is subject to.
• When working with a hydraulic hammer there is an
increased risk of the machine tipping or landing with a
large force on the outrigger on impact. Take this risk
into account and institute appropriate safety
measures to avoid any personal injury or mechanical
damage.
Rotation function
• If there is a breakdown in the machine's rotation
mechanism the machine's upper part may rotate
freely, potentially causing personal injury or
mechanical damage. Keep your distance.
• The machine is most stable when working directly
forwards or backwards. When the machine's upper
part rotates to the side, the outriggers should be down
and the arm system manoeuvred so that it is as close
to the ground as possible.
• In some cases it can be difficult to predict the direction
of rotation. Operate the turning motion carefully until
you have apprehended the direction of rotation.
SAFETY INSTRUCTIONS
Arm system
• Do not use the arm system and the rotation function
for striking, demolishing or scraping.
• Do not work with the arm if the machine's outriggers
are folded. The outriggers provide stability and reduce
the risk of the machine tipping.
• When the arm system's reach is being used, the load
increases as does the risk of tipping. Position the
machine as close to the working object as possible.
• Do not secure the machine to fixed objects, e.g. walls,
to increase the force on the working object. Both the
machine and the tool can be subject to overloading.
• Do not work with the machine's cylinders in the inner
or outer end positions to avoid overloading. Leave a
few centimetres to the maximum position. The
hydraulic oil then has a greater capacity to alleviate
impacts and vibrations.
• There are two working positions that put a lot of strain
on individual cylinders.
Cylinders 1 and 2 are in their outer positions and the
hammer is working in the upward direction. Never
operate the cylinders to their end positions.
Cylinder 3 is in its outer position and the hammer is
working in the downward direction. Never operate the
cylinders to their end positions.
