DESCRIPTION:
Bobcat 642-B Operators Manual – PDF DOWNLOAD
FOREWORD:
- This book is written to give the owner/operator necessary operating, servicing and preventive maintenance instructions for the Model 642 Bobcat loader. Read this manual completely and know the loader before operating and servicing it.
- To find a section, put thumb on the tab and turn pages until correct section is reached. For any extra information needed, see your Bobcat dealer. Do not do any service procedures that are not in the OPERATOR’S MANUAL! Only service personnel that have had training in service of the Bobcat loader can do these service procedures.
- If extra Parts Books, Service Manuals or Operator’s Manuals are needed, they are available through the Bobcat dealer in your area for an added cost.
SAFETY INSTRUCTIONS:
A. SAFETY IS YOUR 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 which are common for off highway, rough terrain applications but are not unique for use of 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 an area with explosive dusts or gases or so that the engine exhaust can contact 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. The dealer demonstrates the safe operation of the loader according to the manufacturer’s instructional materials which are also available to all 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. 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.
