NOTE
This operator’s manual does not contain instructions on how to carry out extensive servicing or repairs. This type of work must only be performed by qualified specialists
Basic information
- In Germany, the following rules must be followed when driving on public roads: Loaders with a maximum speed of up to 20 km/h require no approval. They do however require an operating license, which is issued by the motor vehicles registration office.
- In addition, the name (first name and surname) and the place of residence or the company name and the location of the company’s registered office must be clearly displayed on the left-hand side of the loader in non-smudging lettering (§64b of the German Road Traffic Licensing Regulations, StZVO).
- The operator is responsible for ensuring that appropriate insurance cover is in place. The operator must check with his insurance provider whether or not the loader is covered under the terms of his public liability insurance, or whether he needs to take out separate third party insurance for this purpose. Every new user must be instructed before using the loader for the first time.
Notes on using the operator’s manual:
• Read the operator’s manual carefully before using the
loader.
• Observe all safety instructions.
• Follow the regulations and laws which are applicable in
the place of use.
• Follow the regulations of the federal association of statutory
accident insurances (VGB).
• Always keep the operator’s manual in a clean and orderly
state together with the loader.
- Symbols will he used to highlight any hazards to persons or material which cannot be ruled out during the course of normal work which is carried out in accordance with the proper use of the loader. Descriptions relate to the direction of travel of the loader, so directional information should always be interpreted looking in the direction of travel
