SAFETY INSTRUCTIONS SAFETY IS THE OPERATOR’S RESPONSIBILITY:
- The Skid Steer Loader is a highly maneuverable and compact machine. In operation, it is rugged and useful under a wide variety of conditions. This presents an operator with hazards associated with off highway, rough terrain applications. The loader has an internal combustion engine with resultant heat and exhaust.
- All exhaust gases can kill or cause liness so the loader must be used with adequate ventilation. The loader has a spark arrestor muttler which is required for operation in certain areas. The dealer explains the capabilities and restrictions of the loader and attachments for each application.
- The dealer demonstrates the safe operation of the loader according to Melroe’s instructional materials which are also available to operators.
- The dealer can also identity unsafe modifications or use of unapproved attachments. The attachments and buckets are designed for rated capacity and secure fastening to the loader. The user must check with the dealer, or Melroe Company Iterature, to determine safe loads of materials of specified densities for his loader attachment combination.
