• Activate the machine functionality of collecting dust (water flushing, water mist, or dust
collector) during drilling. Rock dust is created during the drilling process and is harmful
to the health.
• Stay clear from the exhaust cleaning unit and the exhaust pipes on exhaust openings.
High temperature gases escape from the unit.
• Switch off the diesel engine before refueling. Do not handle flammable liquids near hot
surfaces, sparks, or a naked flame.
• During regeneration the exhaust gases and the exhaust system become extremely
hot. Do not touch the exhaust system. Do not cover the exhaust system or expose it to
any flammable materials.
• Perform standstill regeneration only on an open terrain and within a safe distance to
flammable objects.
4.6 Safety Precautions during Service and Maintenance
• Turn off the machine.
• Switch off the main power supply.
• Switch off the battery isolation switch and secure it with a security pin.
• Follow maintenance procedures in accordance with the maintenance schedule.
• Before working on the machine, make sure that all parts are cooled down.
• Start service or maintenance on the machine only when the machine is on firm and
level ground.
• Make sure that the work area is illuminated and clean.
• Make sure that systems are depressurized before starting service or maintenance.
• Make sure that the electrical system is de-energized before starting service or mainte-
nance.
• Secure and strap moveable components before starting service or maintenance.
• If one or more of the following conditions are required for fault-finding or other work,
the task must be done by at least two people. One person must be within the reach of
an emergency stop while having a good overview of the work being done.
– The motors or engines are switched on.
– The hydraulic pumps are activated.
– The hydraulic, pneumatic, or water systems are pressurized.
– The electric power is switched on.
4.7 Safety Guidelines, Working with Pressurized
Components
• Pressurized components must not be exposed to welding or heat treatment.
• Safety equipment such as pressure gauges, over-pressure control devices, and safety
valves must be used while working with pressurized components.
• Installation, design, and connections related to the pressure valve must not be modi-
fied.
4.8 Safety Guidelines, Working with Compressor
• Stop the machine if there is an indication that the compressor is overheated.
• Do not open any inspection hatch until the equipment has cooled down.
• Check and maintain the safety devices such as safety valves and over-pressure de-
vices regularly.
