Husqvarna DXR250 Operator's Manual page 22

Cylinder 3 is in its outer position and the hammer is
working in the downward direction. Never operate the
cylinders to their end positions.

• 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.

SAFETY INSTRUCTIONS
• 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.
Sloping ground
• Sloping surfaces, stairs, ramps etc. can constitute
major risks when moving and working. With gradients
in excess of 30° in the machine´s lenghtwise 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 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 involuntary.
• Check that there is sufficient 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!
