GENERAL INFORMATION :
Basic information :

• Your loader was designed for heavy work conditions. Your loader stands out for its sturdiness, large load capacity,
  and ease of operation. Your loader has a spacious cab, with ROPS/FOPS certification. Your loader provides broad
  visibility and more comfort for the operator, with air conditioning, heating, and simple, smooth controls.
• The engine offers high torque, high performance, reliability, and low consumption. The engine also has fewer moving
  parts, which means less wear and lower maintenance cost, as well as integrated components that facilitate access.
• The transmission is Powershift the mechanical drive type. This system offers feather-ability for loading, which is
  activated by a button on the panel. When activated, just press the brake pedal to transfer more power to the loader
  engine instantly. This guarantees faster lift cycles with a full bucket.
• Both front and rear HD axles have a slip limiter (for extreme applications). This increases the productivity, the traction
  capacity, and the service life of the tires.
• The oil bath disk braking system is driven by single pedal and has hydraulic activation. This system guarantees better
  control and braking efficiency. Each brake circuit is equipped with a nitrogen accumulator, which guarantees greater
  braking efficiency.

Intended use :

Do NOT use your loader for operations other than those specified and which are not described in this manual, to
prevent serious harm to people or damage to the machine. The manufacturer and your dealer are not responsible
for damages caused by improper use.

• With standard equipment and authorized implements, your loader designed
  for excavation and earth movement operations. These include land leveling, truck loading, and material re-handling
  (described in this manual).
• If you want to use the loader for a purpose – for example, logging – that requires special
  implements or equipment, consult your authorized CASE CONSTRUCTION dealer
