Introductory remarks:
Please read the operating instructions carefully before putting an earth-moving machine into operation and strictly follow the remarks for a safe operation.
- National safety regulations – e.g. the Accident Prevention Regulations, „Earth-Moving Machinery“ (VBG 40) and „Vehicles“ (VBG 12), in the Federal Republic of Germany – must also be complied with.
- In addition to the operating instructions, legal regulations governing road traffic and road safety measures must also be observed. Such requirements could also apply in respect of handling hazardous goods or the wearing of personal safety equipment, for example.
- Furthermore, safety laws governing work in particular locations (tunnels, adits, quarries, pontoons, contaminated areas, etc.) must likewise be observed.
Correct use:
The earth-moving machine with normal shovel equipment is only to be used for work which is suitable for the machine’s functions and its attachment.
- Such work includes the digging, loading, displacing and dumping out the earth, stones or other materials and the loading of these materials and the loading of these materials onto lorries, conveyor belts or other means of transportation. The transport of the loading material, however, is mainly carried out by moving the earth-moving machine.
- If special attachments, such as Unishovel, side dump shovel, sweeper, forklift attachment etc. are mounted, special jobs can be done with the attachment.
- Another or additional application, e.g. for transportation of passengers or using the lifting device as working platform etc. is not considered as correct use. The supplier is not liable for subsequent damage. The enduser himself bears the full risk.
- It is part of the correct use to follow the operating and maintenance instructions and to carry out the maintenance as well as to follow the maintenance intervals.
General safety notes:
It is important to refrain from any working methods which impair safety. The earth-moving machine may only be used when it is in a safe, operational condition.
- The manufacturer’s operating instructions must be complied with for operation, maintenance, repair, assembly and transportation.
- The plant operator must provide additional special safety instructions, wherever necessary, for specific local conditions.
- The operating instructions and any information pertaining to the safety must be carefully kept in the driver’s cab.
- The operating instructions and safety notes must be complete and fully readable.
- Safety devices on earth-moving machines must not be deactivated or removed.
