• General information
• The operator’s safety and safety during maintenance are two of the most important things to consider when designing a new loader. As many safety features as possible are incorporated into the design.
• Every year, many accidents take place that could be avoided with a few seconds’ reflection and more careful loader/tractor operation and maintenance. Avoid personal injury.
• Read the following personal safety instructions and insist that everybody who works with you, or for you, also complies with the instructions.
• Only use implements that are approved by the manufacturer for use with the loader and control system. Incorrectly designed implements may cause personal injury and damage to the loader.
• For this reason, do not install third party implements without making sure they have been approved by the loader manufacturer.
