Work area safety
The machine’s risk area
Nobody is permitted to be within the machine’s risk
area when work is underway.
• When working at a height, for instance on roofs,
platforms and the like, increase the size of the risk
area. Defi ne and cordon off the risk area at ground
level and ensure that no material can fall down and
cause injury.
• Ensure when cutting that no material can become
loose and fall, causing operating injury. Take great
care when working on sloping ground.
• Do not use the machine in environments where
there is a risk of explosion. Take the risk of spark
formation into account when working in fl ammable
environments.
• Always check and mark where electricity cables
and pipelines are routed.
• The air in confi ned spaces can rapidly become
harmful to health due to, for example, dust and
gases. Use protective equipment and ensure that
there is satisfactory ventilation.
Electrical safety
• Check that the main voltage corresponds with the
machine’s rating plate.
The working area is limited by the machine’s reach,
however, the risk area varies depending on working
method, work object, surface etc. Study possible risks
before starting work. If conditions change during the
course of the work, the risk area must be redefi ned.
Workplace
• Defi ne and cordon off the risk area. Nobody is per-
mitted to be within the machine’s risk area when
work is underway.
• Ensure that the working area is suffi ciently illumi-
nated to create a safe working environment.
• The machine can be remote controlled over long
distances. Do not operate the machine unless you
have clear supervision of the machine and its risk
area.
• Never start working with the machine until the
working area has been cleared of obstacles.
• Be on the alert when working in environments
where there is a substantial risk of slipping due to
unevenness, loose material, oil, ice or suchlike.
• The machine must be connected to a functioning
protective earth.
• Check all cables and connections. Damaged
electric cables can impede the machine’s function
and lead to personal injuries. Do not use damaged
connectors or cables.
• The electric cabinet must not be opened when the
machine is connected to power. Some components
in the electric cabinet are permanently live, even if
the machine is turned off.
• Always connect the machine through an earth-fault
breaker with personal protection, i.e. an earth fault
circuit breaker that trips at an earth fault of 30 mA.
• The machine must never be driven to such a depth
in water that it reaches up to the machine’s equipment. The equipment can be damaged and the
machine can be live, resulting in personal injuries.
• Ensure that the power cable cannot be run over.
Take particular care when moving or when the
outriggers are being retracted or extended. Risk of
electric shock.
• To avoid overheating do not use an electric cable
while it is coiled.
• Always de-energize the machine when carrying
out maintenance work and when it is not in use.
Disconnect the power cable and place it so that it

SAFETY INSTRUCTIONS
English - 9
Personal safety
• Never use the machine if you are tired, if you have
consumed alcohol, or if you are taking other drugs
or medication that can affect your vision, judgement or co-ordination.
• Wear personal protective equipment. See instructions under the heading ”Personal protective
equipment”.
• Chemicals such as degreasing agent, grease and
hydraulic fl uid can give rise to allergies in conjunc-
tion with repeated skin contact. Avoid contact with
the skin and use protective equipment.
• When in use, the machine can generate dust and
fumes that can contain harmful chemicals. Know
the nature of the material being worked on and
wear appropriate dust mask or respirator protection.
A face mask is especially important when working indoors due to the limited ventilation. In some
situations it can also be suitable to apply water in
order to decrease the dust.
• Do not stand on the control cable or the power cable as there is a risk of your feet becoming tangled.
• Do not use remote control with cable steering while
working or moving where there is a risk that the
machine can topple. The operator must be disengaged from the machine.
• An incorrect manoeuvre or unforeseeable incident
can result in collapse. Never stand underneath the
work object.
• Never stand where there is a risk of being crushed.
The machine can rapidly change position. Never
stand underneath a raised arm, even if the machine
is turned off.
• Reduce the risk when working alone by making
sure that an emergency alarm is available via mobile phone or other equipment.
• When moving on a fl at surface you must always
walk behind or at the side of the machine. When
working or moving on a sloping surface position
yourself above the machine.
Operation
General
• Only authorized and trained operators are permitted to operate the machine and its tools.
• Never use a defective machine. Carry out inspections, maintenance and service in accordance with
the instructions in the Operator’s Manual.
• Rectify any faults or damage that occur immediately. Prevent the machine from being used before
the fault has been rectifi ed.
• The machine has been tested and approved solely
with equipment supplied and recommended by the
manufacturer.
• Under no circumstances should you modify the
original design of the machine without approval
from the manufacturer. Always use original spare
parts. Unauthorized modifi cations and/or accesso-
ries may lead to serious injury or death to the user
or others.
• Do not modify the machine’s safety devices and
check regularly that they are working properly. The
machine must not be driven if protective plates,
protective covers, safety switches or other protective devices are not fi tted or are defective.
• Make sure all nuts and bolts are tightened correctly.
• The machine must be kept clean. Signs and stickers must be fully legible.
• Follow the machine’s and the tool’s instructions
carefully when changing tools in order to avoid
injuries.
• Turn off the electricity supply to the machine before
you take off the remote control or when you leave
the machine to avoid the risk of unintentional operation.
• Firm handling of the joysticks does not make the
machine stronger or faster. On the contrary, the
joysticks can buckle with unnecessary repairs as a
consequence.
• Do not lift the remote control by the joysticks.
Education and training
• New operators must be trained by experienced
operators with the capacity to use sound judgment
when supervising the work.
• Practice stopping the machine and locating the
stop button quickly. Practice manoeuvring in different directions, on a slope and different surfaces.
• Test the machine’s stability under controlled conditions. Practice rapid evacuation.
• On completion of the training, the operator should
be properly acquainted with the machine’s limitations with respect to reach, capacity and stability,
and also be able to manoeuvre the machine safely.
SAFETY INSTRUCTIONS
10 - English
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 fl ash 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 diffi cult 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.
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.
• Never use the telescopic arm to press the tool
against the working object.
• Do not secure the machine to fi xed objects, e.g.
walls, to increase the force on the working object.
Both the machine and the tool can be subject to
overloading.
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 diffi cult to predict the
direction of rotation. Operate the turning motion
carefully until you have apprehended the direction
of rotation.
• 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 fl uid 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.
SAFETY INSTRUCTIONS
Proximity to edges
• Inadequate surfaces, incorrect operation, etc. can
cause the machine to slide. Exercise particular caution when working close to shafts, beside trenches
or when working at height.
• Always anchor the machine and loose tools when
working close to edges.
• Ensure that the machine is stable and does not
move closer to the edge while work is in progress.
• Ensure that the underlying surface has satisfactory
bearing capacity. Vibrations affect bearing capacity.
Uneven surfaces
• Extend the outriggers so that they are positioned
just above the surface when moving over uneven
areas.
• In some cases the arm can be used to lift the drive
gear over bumps. The arm must never be rotated
or raised up high due to the risk of overturning.
• Uneven surfaces can cause the machine to lean
to such an extent that it overturns. Manoeuvre the
machine’s arm system inwards in order to move
the centre of gravity as close to the machine’s centre as possible to reduce the risk of tipping.
• Surfaces with a poor bearing capacity can cause
the machine to change direction or even overturn
without warning. Always check the bearing capacity and properties of the surface before starting the
machine. Also be alert for holes that are covered
by materials with a poor bearing capacity.
• The machine’s caterpillar tracks produce a low
level of friction against smooth surfaces. Water,
dust and contaminants can further reduce friction.
When defi ning the risk area you should take into
account the fact that less friction increases the risk
of the machine starting to slide.
Confi ned spaces
• Working in confi ned spaces with extended outrig-
gers can be diffi cult. The machine’s stability is con-
siderably diminished. Adapt the work accordingly.
There is an increased risk of the machine overturning if the arm swings outside the outrigger.
Sloping ground
• Sloping surfaces, stairs, ramps etc. can constitute
major risks when moving and working. With gradients in excess of 35° there is a risk of the machine
tipping.
• The machine’s arm system and outriggers must be
positioned as low as possible to reduce the risk of
tipping.
• Do not run the caterpillar tracks and tower simultaneously when moving on a sloping surface to
reduce the risk of unexpected motion.
• Avoid driving sideways on slopes - drive straight
up or down. Ensure that the machine’s arm system
is turned upwards in sloping terrain.
• Always position yourself above the machine when
driving on a slope. There is a risk of the machine
tipping.
• Anchor the machine if there is a risk of the machine
starting to move.
• Check that there is suffi cient bearing capacity
when driving on ramps and stairs.
Proximity to ducts and pipes
• Always check and mark where electricity cables
and pipelines are routed. Ensure that electricity
cables and pipelines are shut off.
• The machine must not get close to overhead cables. The current can “jump” over long distances.
Falling material
• Watch out for demolition material becoming loose
when cutting. Use personal safety equipment and
keep your distance.
• Ensure that the vibrations from the hydraulic hammer do not cause cracks to form or stones or other
material to loosen and cause personal injury or
damage to property. Keep your distance!
• When moving in confi ned spaces it is possible to
reduce the width of the tracks, increasing the risk
of the machine overturning. There is an increased
risk of the machine overturning if the arm swings
outside the outrigger.
English - 11
Securing the machine
• Secure the machine with approved tightening
straps. Use the machine’s lifting eye bolts. Ensure
that no part of the machine are squashed or damaged by the tightening straps. It is a good idea to
cover the machine.
• Tools and other equipment must be secured with
separate tightening straps.
• Regularly check that the load is secure during
transportation.
Storage
• Remove the tool from the machine.
• Retract the arm system to attain a centre of gravity
that is as low as possible and to save space.
• Store the equipment in a lockable area so that it is
out of reach of children and unauthorized persons.
• Store the machine and its equipment in a dry and
frost proof place.
Towing
The machine is not designed to be towed. When the
machine is depressurized, the drive motor’s parking
brakes are activated and the caterpillar tracks cannot
rotate. Only tow the machine if its position constitutes
a risk and there is no other solution. Tow it for the
shortest possible distance.
• If possible, retract the outriggers before towing the
machine in order to reduce the risk of them getting
stuck and being damaged.
• To minimize the load on the towing device and
mechanical components, reduce the friction by
preparing the route that the machine is going to be
towed.
• If possible tow in the direction of the tracks.
• Use the lifting eye bolts to connect to the towing device. Use a towing device intended for the
particular load.
• Parts can loosen during towing. Keep your distance!
SAFETY INSTRUCTIONS
12 - English
Transport and storage
Lifting the machine
• When lifting the machine there is a risk of injuring
persons or damaging the machine or the surroundings. Defi ne the risk area and check that nobody is
present within the area when lifting.
• Use an approved lifting device to secure and lift
heavy machine parts. Also ensure that there is
equipment to secure machine parts mechanically.
• Retract the arm system. The centre of gravity must
be as close to the machine’s centre as possible.
• The lifting equipment must be attached at all the
machine’s lifting eye bolts.
• Lift slowly and carefully. Make sure that the lift is in
equilibrium and if the machine starts to lean, rectify
it by using an alternative lifting device or change
the position of the arm system.
• Ensure that the machine’s parts are not crushed or
damaged when lifting and that the machine does
not hit surrounding objects.
Loading and unloading using a ramp
• Ensure that the ramp is intact and the right size for
the machine.
• Check that the ramp is free of oil, mud or anything
else that might make it slippery.
• Ensure that the ramp is properly secured to both the
vehicle and the ground. The vehicle being used for
transportation must also be secured so that it cannot
move.
Transport
• The machine may only be transported on a fl atbed
truck or a trailer that is approved for the machine’s
weight, refer to the machine’s rating plate. The
remote control must be properly protected in the
vehicle during transportation.
• Check applicable road traffi c regulations before
transporting on public roads.
The machine’s position on the loading platform
• Position the machine against the front edge of the
platform in order to reduce the risk of it sliding
forward if the vehicle brakes.
• Manoeuvre the arm system so that it is resting
against the platform, positioned as low as possible.
Extend the outriggers without lifting the machine.
SAFETY INSTRUCTIONS
Maintenance and service
Most accidents involving machines occur during trouble shooting, service and maintenance as staff have
to locate themselves within the machine’s risk area.
Prevent accidents by being alert and by planning and
preparing the work. You can also refer to ’Preparations
for maintenance and service” in the ’Maintenance and
service” section.
• The user must only carry out the maintenance and
service work described in this Operator’s Manual.
More extensive work must be carried out by an
authorized service workshop.
• Never carry out repairs without having the necessary expertise.
• Only trained service personnel are permitted to
intervene in the electrical or hydraulic systems.
• Use personal protective equipment as well as
equipment to mechanically secure machine components during maintenance and service.
• Set out clear signs to inform persons in the vicinity
that maintenance work is in progress.
• If service operations or trouble shooting does not
require the machine to be switched on, the power
cable must be removed and positioned so that it
cannot be connected by mistake.
• Ensure there is no current to the machine by removing the power cable before opening or removing the electric cabinet or any other component
that contains electrical current.
• Pipe and hose couplings can remain pressurized
despite the motor being switched off and the power cable disconnected. It must always be assumed
that hydraulic hoses are pressurized and they must
be opened with great care. Relieve the pressure on
the arm system by resting it on the ground and turn
off the electric motor before undoing the hoses.
• Never try to stop hydraulic fl uid leaking from a bro-
ken hose by hand. Finely dispersed hydraulic fl uid
at high pressure can permeate under the skin and
cause very severe injuries.
• When dismantling machine parts, heavy components can start moving or fall down. Secure moving
parts mechanically before loosening screw joints or
hydraulic hoses.
• Use an approved lifting device to secure and lift
heavy machine parts.
• Several components heat up during work with the
machine. Do not commence any servicing or maintenance tasks until the machine has cooled.
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• The machine’s movements can be defective if a
terminal, cable or hose is incorrectly assembled.
Exercise caution during test runs and be prepared
to turn off the machine immediately in the event of
a fault.
The machine’s
safety features
The machine’s safety features can be divided into
safety features for personal protection and those for
mechanical protection. Some of the safety features
provide both mechanical and personal protection.
WARNING!
Do not modify the machine’s safety devices and
check regularly that they are working properly.
The machine must not be driven if protective
plates, protective covers, safety switches or
other protective devices are not fi tted or are
defective.
Personal protection
Indication of zero position
If either of the joysticks is in an operative position
when the remote control is started, the function will be
blocked. The operator is informed of this by means of
an error message appearing on the screen. To reset
the function, the remote control must be turned off
and on again.
The function also protects against faults in the potentiometer or cable breaks.
Signal voltage limitation
Signal voltage limitation prevents the machine executing unexpected movements in the event of a cable
breaking or a short-circuit.
The voltage level of the control signals is limited to
within a maximum and minimum value. If the voltage
level falls outside the permitted interval, the machine
stops.
Joystick guard
The safety feature reduces the risk of unintentionally
moving the machine by locking the control circuit if
the joysticks have been in neutral for three seconds.
The control circuit is activated by means of the left
button on the right joystick. It is activated when the
button is released. This guards against fi xing the but-
ton in an active position.
Radio block
If the remote control has been turned off for two
minutes the electronic unit in the machine is blocked
to radio signals. It is not possible to restart the machine until the supply voltage to the machine has been
turned off and on again.
The safety feature ensures that the operator knows
which machine will start and that the correct remote
control is being used for the machine. This is particularly important when there are several machines at the
same workplace.

SAFETY INSTRUCTIONS
Identity code
The remote control and the machine are connected
by means of a pre-programmed ID code. The ID code
ensures that the right remote control is used for the
right machine.
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 fl ash three times. Do not activate the remote con-
trol before you have ensured that the correct machine
is being operated.
When steering the machine using cables, the ID code
is suppressed and the same remote control can be
used for different machines if these have the same
control system version.
Automatic frequency hopping
In the event of interference in the communication, the
frequency changes automatically to guarantee interference-free transmission.
Emergency stop/machine stop
When the machine stop on the remote control is
pressed, the power to the circuits controlling the
communication with the machine is interrupted. The
machine engine stops due to the interruption of the
transfer of signals to the machine’s electronic device.
The emergency stop on the machine switches off the
main power to the machine.
Protective earth
The machine and its components are connected to
grounding conductors in the power cable. If there is a
fault, a fuse is tripped and the current is disconnected.
The machine must be connected to a power point with
a protective earth. If there are no grounding conductors, or if they are connected incorrectly, have come
off or are loose in a terminal, the current will remain
connected and touching the machine can be highly
dangerous.
If there is reason to believe that the protective earth
has been damaged, the machine must be turned off
and the power cable removed until such time as the
protective earth has been restored.
Always connect the machine through an earth-fault
breaker with personal protection, i.e. an earth fault
circuit breaker that trips at an earth fault of 30 mA.
Hydraulic brake
Hydraulic motors are used when moving the machine.
All hydraulic motors are fi tted with brakes. These
hydraulic motors contain counter balance valves that
prevent uncontrolled fl ow through the motor, e.g. when
manoeuvring down a slope or when the machine is
parked. The counter balance valve closes the tank
opening when the drive motors are not being operated.
Mechanical brake
The machine’s drive motors are equipped with a mechanical parking brake. The machine is braked until its
drive function is activated.
Mechanical protection
Automatic phase rotation relay
The automatic phase rotation relay prevents the electric motor starting with the wrong rotation direction
thus causing mechanical damage.
Motor protection
To prevent overloading, the motor is equipped with
bimetallic relays in the motor linings that disconnect
the power if the motor gets too hot.
If the motor is too hot it is not possible to operate the
tools. The rest of the machine’s functions can be run
at half speed in order to facilitate evacuation of the
machine from risky environments.
Once the motor’s temperature has fallen to a normal
working temperature all functions can be used again.
The machine’s softstarter is fi tted with a motor cut-out
that trips if the current is too high for too long a period.
The machine’s functions return to normal position after
three minutes.
Fuses
Fuses are used to protect the following components
as well as to prevent fi re in conjunction with faults or if
electrical components are overloaded.
Pressure relief valves
The machine’s hydraulic system is equipped with
pressure relief valves. They protect the hydraulic
system against too high pressure and the mechanical
components against overloading.
Pump-around valve
The pump-around valve drains the hydraulic fl ow into
a tank and relieves the pressure on the hydraulic system. No pressure enters the cylinders and it prevents
the risk of unforeseen movements. This happens, for
example, after three seconds of inactivity.

SAFETY INSTRUCTIONS
External environmental
factors
Temperature
The ambient temperature, both heat and cold, affects
the machine’s operational reliability. Temperature
variations also have an impact as they produce an
increased risk of condensation forming in the machine’s tanks.
Heat
NB! There is an increased risk of overheating in warm
environments. Both the machine’s hydraulic system
and electronic components can be damaged.
The maximum working temperature for hydraulic fl uid
is 90°C (194°F). Overheating results in deposits forming in the fl uid, leading to increased wear, damaged
seals and leakage. Overheated hydraulic fl uid pro-
vides poor lubrication, resulting in inferior performance.
To avoid overheating:
• Keep the machine clean, in particular its cooler.
• Ensure that there is good ventilation when working
indoors.
• Radiant heat can cause local heating that damages parts of the machine. Screen off vulnerable
components.
Moisture
When working in damp environments the operator
should ensure that electrical components, connectors
for example, are not submerged in water.
The machine must never be driven to such a depth in
water that it reaches up to the machine’s equipment.
The equipment can be damaged and the machine can
be live, resulting in personal injuries.
Dust and particles
Dust and particles can block the machine’s cooler,
cause overheating and increase wear on the machine’s bearings and shafts. Clean and lubricate the
machine regularly.
The hydraulic system is extremely sensitive to contaminants. Small particles can cause breakdowns and
increase wear in the components.
There is a high risk of contamination in conjunction
with servicing and repairs when the hydraulic system
is opened.
Contamination of the hydraulic system can be
prevented by:
• Keeping the machine clean, particularly before
servicing, repairs or changing tools.
• Carrying out daily inspections.
• Carrying out regular servicing.
• Additional cooling is required if there are high
ambient temperatures. Supply the machine with
forced cooling using compressed air.
To avoid damage to the machine:
• Change hydraulic fl uid and fi lters more frequently.
• Check the machine’s seals to prevent dirt in the
hydraulic system due to broken seals.
• Rubber caterpillar tracks must not be exposed to
temperatures of over 70°C (158°F). In hotter environments steel tracks have to be used.
Cold
Do not use maximum pump pressure if the hydraulic
fl uid is less than 10°C (50°F). Allow the machine to
warm up slowly. Warm up the lower section by running the caterpillar tracks, fi rst slowly and then more
quickly with the outriggers extended. Move the upper
section back and forth and operate all cylinders in the
arm system without load. The machine is ready for
use when its temperature has risen to around 40°C
(104°F).

The machine’s functions
The machine’s functions are operated by means of
interaction between the hydraulic system, the electric
system and the control system.
A brief description of the machine’s functions follows
below.
Arm system
The arm system is divided into three parts in order to
provide extensive movement, a long reach and compactness. Expanding shafts minimize the risk of play
in the joints.
By running cylinder 1 and cylinder 2 in parallel, the
machine’s reach can be modifi ed without moving the
machine.
Caterpillar tracks
The caterpillar tracks are driven individually by hydraulic motors. The machine can be turned by operating
the caterpillar tracks at different speeds. Operating the
tracks in different directions enables the machine to
make tight manoeuvres. When the drive function is not
activated the passive brakes lock the drive motors.
The machine is also equipped with a telescopic arm
that provides additional reach. Work as close to the
work object as possible as this makes optimum use of
the power to the arm system and cylinders.
Tower
The tower has unlimited rotation, which means that is
possible to work in several directions without having
to move the machine. The machine is equipped with a
slew brake. When the rotating function is not activated, the function is braked by means of passive brakes.
NB! The machine’s rotating function must not be subject to overload, e.g. caused by tools that exceed the
weight limit.
In transport mode, the caterpillar tracks and tower can
be manoeuvred simultaneously. The function can be
used, for example, when the machine is being operated in confi ned spaces.
Outriggers
The main function of the outriggers is to give the
machine stability. They must always be used when
working with the machine.
Tools
The machine should be fi tted with tools that are ap-
propriate for the tasks that are to be carried out. The
weight and performance requirement of the tool is
decisive in ascertaining whether it is suitable for use
with the machine. Further information is available in
the ’Tools” and ’Technical data” chapters and the tool
supplier’s instructions.
External tool (optional)
The machine has been prepared with connections
for external hand tools for the machine’s hydraulic
system.

HYDRAULIC SYSTEM
General
The task of the hydraulic system is to operate the machine’s functions by means of hydraulic pressure and
fl ow. The system consists of hydraulic pump, tank,
cooler, hydraulic motor, hydraulic cylinders, fi lters and
valves of various kinds. Hoses or pipes connect the
components with each other.
Valves are used to control the hydraulic system’s
pressure, volume rate of fl ow and direction. Pressure
control valves limit or reduce the pressure to the value
required. Volume control valves affect the hydraulic
fl uid’s fl ow and thereby the speed of the functions.
Direction control valves direct the hydraulic fl uid to the
machine’s different functions.
The hydraulic pump is of the variable displacement
type and delivers a fl ow of 0-65 l/min (0-17 gal/min).
Main pressure
The hydraulic system has two main pressures.
• Standard pressure is 200 Bar.
• Increased main pressure is 250 Bar.
Increased main pressure is used when the outriggers
are down and when concrete cutters are used with
increased tool pressure.
If concrete cutters with increased tool pressure are
operated at the same time as another function, the
machine returns to standard pressure.
Pressure cut-off
Functions equipped with pressure cut-off have a
reduced pre-set maximum pressure. The telescopic
arm is equipped with a pressure cut-off that produces
a maximum of 180 Bar.
Cooler
The cooler has an integrated bypass valve that protects against overpressure in conjunction with, for
example, cold start.
