Safety Information
• Avoid contact with hot parts, such as the engine block or the exhaust system during the
operation of the machine and for some time afterwards – danger of burns!
• Retainer pins can fly out or splinter when struck with force – danger of personal injury!
• Do not use starting fuel! This especially applies to those cases in which a heater plug
(intake-air preheating) is used at the same time – danger of explosions!
• Apply special care when working on the fuel system – increased danger of fire!
Tracks • Repair work on the tracks must be performed only by trained technical staff or by an
authorized workshop.
• Malfunctioning tracks reduce the machine's operational safety. Therefore, check the
tracks regularly for cracks, cuts or other damage.
• Check track tension at regular intervals.
Electric energy • Use only original fuses with the specified current rating.
• In case of electrical system malfunctions, switch off the machine immediately,
disconnect the battery (by using the battery master switch), and perform
troubleshooting procedures.
• When working with the machine, maintain a safe distance from overhead electric lines!
If work must be performed close to overhead lines, the equipment and attachments
must be kept well away from them.
• If the machine comes into contact with a live wire:
• Immediately drive the machine out of the danger area.
• Warn others against approaching and touching the machine.
• Do not leave the machine until the line that has been touched or damaged has been
safely de-energized!
• Make sure that work on the electric system is performed only by a technician with
appropriate training, in accordance with applicable electrical engineering codes.
• Inspect and check the electrical equipment of the machine at regular intervals. Defects
such as loose connections or scorched cables must be repaired immediately.
• Observe the operating voltage of the machine/attachments. The voltages must be
compatible (12 volts) and confirm that an appropriate fuse or circuit breaker is
incorporated in the system to prevent damage from malfunction or short circuit.
• Always remove the grounding strap from the battery when working on the electric
system.
Hydraulics • Check all lines, hoses, and threaded couplers and fittings regularly for leaks and
obvious damage. Repair any damage and leaks immediately. Splashed oil can cause
injury and fire!
• In accordance with the Operator's Manual/instructions for the respective assembly,
release the pressure in all system sections and pressure lines (hydraulic system) to be
opened before perform any implementing/repair work!
• Hydraulic and compressed-air lines must be laid and fitted properly. Make sure no
connections are interchanged. The fittings, lengths and quality of the hoses must
comply with the technical requirements
Noise • Close all doors and windows if practical.
• Wear ear protection. This is especially important when performing hammer operations
or working in enclosed areas.
