The Machine's Functions - Husqvarna DXR250 Operator's Manual

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.
NOTICE! The machine's rotating function must not be
subject to overload, e.g. caused by tools that exceed the
weight limit.

INTRODUCTION
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.
