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 illness so the loader must be used with adequate ventilation. The loader has a spark arrestor muffler 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 identify 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 literature, to determine safe loads of materials of specified densities for his loader–attachment combination.

The following publications provide information on the safe use and maintenance of the loader and attachments:• The Delivery Report is used to assure that complete instructions have been given to the new owner and that the machine is in safe operating condition.• The Operation and Maintenance Manual delivered with the loader gives operating information as well as routine maintenance and service procedures. It is a part of the loader and can be stored in a container (later models) provided inside the cab. Replacement Operation and Maintenance Manuals can be ordered from your Bobcat loader dealer.• The loader has machine signs (decals) which instruct on the safe operation and care. The signs and their locations are shown in the Operation and Maintenance Manual. Replacement signs are available from your Bobcat loader dealer.• The loader has a plastic Operator’s Handbook fastened to the operator cab. Its brief instructions are convenient to the operator. The Handbook is available from your dealer in an English edition or one of many other languages. See your Bobcat dealer for more information on translated versions.• The EMI Safety Manual (available in Spanish) delivered with the loader gives general safety information.• The Service Manual and Parts Manual are available from your dealer for use by mechanics to do shop–type service and repair work.• The Skid–Steer Loader Operator Training Course is available through your local Bobcat dealer. This course provides information for safe and efficient operation of the Bobcat loader. The course is available in English and Spanish versions.• The Bobcat Skid–Steer Loader Safety Video is available from your Bobcat Dealer.
