Work area safety

The machine’s risk area

Nobody is permitted to be within the machine’s risk area when work is underway. This also applies for the operator.
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 redefined.

Workplace

• Define and cordon off the risk area. Nobody is permitted to be within the machine’s risk area when work is underway.
• Ensure that the working area is sufficiently illuminated 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. If the view of the machine and its risk area is not good enough a camera system should be used.
• 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.
• Inspect ground conditions, load-bearing structures etc. to prevent materials, machines and staff falling and deal with any risks there might be before starting work.
• When working at a height, for instance on roofs, platforms, etc., increase the size of the risk area.
Define and cordon off the risk area at ground level and ensure that no material can fall down and cause injury.
• 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 flammable
environments.
• Always check and mark where power cables and pipelines are routed.
• The air in confined 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 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 a ground fault circuit interrupter with personal protection, i.e. a ground fault circuit interrupter that trips at a ground 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 cannot be connected by mistake.

Personal safety

WARNING! This machine produces an electromagnetic field during operation.
This field may under some circumstances interfere with active or
passive medical implants. To reduce the risk of serious or fatal injury, we
recommend persons with medical implants consult their physician and the
medical implant manufacturer before operating this machine.

• Never use the machine if you are tired, if you have consumed alcohol, if you are taking other drugs or medication that can affect your vision, judgement or
coordination.
• Wear personal protective equipment. See instructions under the heading ”Personal protective equipment”.
• Chemicals such as degreasing agent, lubrication and hydraulic fluid can give rise to allergies in conjunction with repeated skin contact. Avoid contact with the skin, 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 control while working or moving where there is a risk that the machine can overturn. The operator must be
disengaged from the machine in such conditions.
• An incorrect maneuver or unforeseeable incident can result in collapse of work object. Never stand underneath the work object.
• Never stand where there is a risk of being crushed by the machine. The machine can rapidly change position while working. Never stand underneath a
raised arm, even if the machine is turned off.
• When the machine is powered, the fan of the radiator may begin to rotate. Never put your fingers inside the fan compartment!
• 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 flat surface you must always walk behind or at the side of the machine. When working or moving on an inclined surface, position yourself above the machine.

Operation

General

• Only professional 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 rectified.
• If the machine becomes inoperable, turn off the motor before approaching the machine.
• 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 modifications and/or accessories 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 fitted 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 power supply to the machine before you take the remote control off 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 judgement when supervising the work.
• Practice stopping the machine and locating the stop button quickly. Practice maneuvering 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 maneuver the machine safely.

Maneuvering

General

• If several machines are used at the same workplace there is a risk of mixing up the remote controls.
Switch on the power 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/dozer blade

• When outriggers/dozer blades are folded, the arm must be retracted to minimize the risk of the machine overturning.
• The machine’s outriggers/dozer blade can leave the ground, especially when working with a hydraulic breaker 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 breaker there is an increased risk of the machine tipping or landing with a large force on the outrigger/dozer blades 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 maneuvered 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.

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/ dozer blades are folded. The outriggers/dozer blades 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 centimeters to the end 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 breaker is working in the upward direction. Never operate the cylinders to their end positions.
Cylinder 3 is in its outer position and the breaker is working in the downward direction. Never operate the cylinders to their end positions.

DXR310

• Never use the telescopic arm to press the tool against the working object.

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. Maneuver the machine’s arm system inwards in order to move the
center of gravity as close to the machine’s center 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
defining the risk area you should take into account the fact that less friction increases the risk of the machine starting to slide.

Confined spaces

• Working in confined spaces with extended outriggers can be difficult. The machine’s stability is considerably diminished. Adapt the work accordingly. There is an increased risk of the machine overturning if the arm swings outside the outrigger.
• When moving in confined 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.

Inclined ground

• Inclined surfaces, stairs, ramps etc. can constitute major risks when moving and working. With gradients in excess of 30° in the machine´s lengthwise direction 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 an inclined 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 inclined 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 involuntary.
• Check that there is sufficient bearing capacity when driving on ramps and stairs.

Proximity to ducts and pipes

• Always check and mark where power cables and pipelines are routed. Ensure that power cables and pipelines are shut off.
• The machine must not get close to overhead power lines.

Falling material

• Watch out for demolition material becoming loose when working. Use personal safety equipment and keep your distance.
• Ensure that the vibrations from the hydraulic breaker do not cause cracks to form or stones or other material to loosen and cause personal injury or
damage to property. Keep your distance!

Transport and storage

Lifting the machine

• When lifting the machine there is a risk of injuring persons or damaging the machine or the surroundings. Define 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 center of gravity must be as close to the machine’s center as possible.
• The lifting equipment must be attached at all the machine’s lifting points.
• 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 flatbed 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 traffic 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.
• Maneuver the arm system so that it is resting against
the platform, positioned as low as possible. Extend
the outriggers without lifting the machine.

Securing the load

• Secure the machine with approved tightening straps.
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 center 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 unauthorized persons.
• Store the machine and its equipment in a dry and frost proof place.
• The main switch on the machine can be locked with a padlock to prevent unauthorized persons from starting the machine.

Towing

The machine is not designed to be towed. When the hydraulic system is discharged, 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 damaging them.
• 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 a towing device intended for the particular load.
• Parts can loosen during towing. Keep your distance!

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.
• Never carry out repairs without having the necessary expertise.
• The user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorized service
workshop.
• Use personal protective equipment as well as equipment to mechanically secure machine components during maintenance and service.
• Only trained service personnel are permitted to intervene in the electrical or hydraulic systems.
• 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 itcannot be connected by mistake.
• Ensure there is no power supply to the machine by
removing the power cable before opening or removing the electric cabinet or any other electric component.
• 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, turn off the electric motor and discharge the hydraulic system before undoing the hoses.
• Never try to stop hydraulic oil leaking from a broken hose by hand. Finely dispersed hydraulic oil 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 use of the machine. Do not commence any servicing or maintenance tasks until the machine has cooled down.
• 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.

External environmental factors

Temperature

The ambient temperature, both hot 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 tank.

Heat

NOTICE! 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 oil is 90°C (194°F). Overheating results in deposits forming in the oil, leading to increased wear, damaged seals and leakage. Overheated hydraulic oil provides 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.
• Additional cooling is required if the ambient temperature is over 40°C (104°F).

To avoid damage to the machine:

• Change hydraulic fluid and filters 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 fluid is less than 10°C (50°F). Allow the machine to warm up slowly. Warm up the lower section by running the caterpillar tracks, first 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 (hydraulic fluid) has risen to around 40°C (104°F).

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 bushings 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.
