ARNING! The machine can be a

dangerous tool if used incorrectly or

carelessly, which can cause serious or

fatal injury to the operator or others.

Please read the operator’s manual

carefully and make sure you understand

the instructions before using the machine.

Noise emission to the environment

according to the European Community’s

Directive. The machine’s emission is

speciﬁed in the Technical data chapter

and on the label.

Always wear:

• Tight-ﬁtting, heavy-duty and

comfortable clothing that permits full

freedom of movement.

• Sturdy, non-slip boots or shoes.

• Protective gloves.

• Protective helmet.

• Hearing protection.

• Protective goggles or a visor.

• A breathing mask, gas mask or fresh air helmet must

be used when working in environments where the air

can be harmful to health.

WARNING! Live parts.

WARNING! Ensure that no material can

fall down and cause damage when you

are using the machine.

WARNING! Watch out for demolition

material becoming loose when cutting.

Use personal safety equipment and keep

your distance.

WARNING! Always position yourself

above the machine when driving on a

slope. There is a risk of the machine

tipping.

WARNING! Exercise particular caution

when working close to edges. Ensure that

the machine is stable and does not move

closer to the edge while the work is in

progress. Ensure that the underlying

surface has satisfactory bearing capacity.

Inspections and/or maintenance must

be carried out with the motor switched

off and the power cord disconnected.

Always connect the machine

through an ground fault circuit

interrupter with personal protection,

i.e. an ground fault circuit

interrupter that trips at an ground fault of 30 mA.

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.

The lifting equipment must be attached at

all the machine’s lifting points.

Keep your distance! Nobody is permitted

to be within the machine’s risk area when

work is underway. The machine’s risk area

can vary during the course of the work.

The machine can overturn during

work. During operation the machine

must be positioned as level as

possible and the outriggers must be

fully extended.

Explanation of warning le

vels

The w

arnings are graded in three levels.

ARNING!

CAUTION!

NOTICE!

Note the f

ollowing before

starting:

ARNING! Used if there is a risk of

serious injury or death for the operator

or damage to the surroundings if the

instructions in the manual are not

followed.

UTION! Used if there is a risk of injury

to the operator or damage to the

surroundings if the instructions in the

manual are not followed.

TICE! Used if there is a risk of damage to materials

or the machine if the instructions in the manual are not

followed.

ARNING! Cutting, especially when DRY

cutting, generates dust that comes from

the material being cut, which frequently

contains silica. Silica is a basic

component of sand, quartz, brick clay,

granite and numerous other minerals

and rocks. Exposure to excessive

amount of such dust can cause:

Respiratory disease (affecting your

ability to breath), including chronic

bronchitis, silicosis and pulmonary

ﬁbrosis from exposure to silica.These

diseases may be fatal;

Skin irritation and rash.

Cancer according to NTP* and IARC* */

National Toxicology Program,

International Agency for Research on

Cancer

Take precautionary steps:

Avoid inhalation of and skin contact with

dust, mist and fumes.

Wear and ensure that all bystanders wear

appropriate respiratory protection such

as dust masks designed to ﬁlter out

microscopic particles. (See OSHA 29

CFR Part 1910.1200)

Wet cut when feasible, to minimize dust.

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.

Work as close to the work object as possible as this

makes optimum use of the power to the arm system and

cylinders.

By running cylinder 1 and cylinder 2 in parallel, the

machine’s reach can be modiﬁed without moving the

machine.

DXR310 Telescopic arm

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.

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

maneuvers. When the drive function is not activated the

passive brakes lock the drive motors.

In transport mode, the caterpillar tracks and tower can be

manouvered simultaneously. The function can be used,

for example, when the machine is being operated in

conﬁned spaces.

NOTICE! The machine’s rotating function must not be

subject to overload, e.g. caused by tools that exceed the

weight limit.

INTRODUCTION

English – 9

Outriggers/dozer blade

The main function of the outriggers is to give the machine

stability.They must always be used when working with the

machine.

DXR250 Dozer blades

The main function of the dozer blades is to give the

machine stability. They must always be used when

working with the machine.

Tools

The machine should be ﬁtted with tools that are

appropriate 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.
