SAFETY IS YOUR RESPONSIBILITY:
SAFETY INSTRUCTIONS:
- 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 which are common for off-highway, rough-terrain applications but are not unique for use of the Bobcat loaders.
- The loader has an internal combustion engine with resultant heat and exhaust. All exhaust gases can kill so the loader must be used with adequate ventilation.
- The loader must not be used in space with ex losive dusts or gases or so that the engine exhaust contacts flammable material.
- The loader has a spark arrestor muffler which is required for operation in certain areas. For loader applications, the dealer recommends the capabilities and restrictions of the loader and attachments for each application use.
- The dealer demonstrates the safe operation of the loader according to the manufacturer’s instructional materials which are also available to all operator’s. 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. For each model loader, the user must check with the dealer or manufacturer’s literature to identify each bucket or attachment for safe loads of materials of specified densities.
The following publications provide information on the safe use of the loader and attachments:
