BOBCAT INGERSOLL RAND BL-370 BL-375 Service Manual PDF DOWNLOAD

FOREWORD
This manual is for the Ingersoll-Rand loader mechanic. It provides necessary servicing and
adjustment procedures for the Ingersoll-Rand loader and its component parts and systems. Refer to
the Operation & Maintenance Manual for operating instructions, Starting procedure, daily checks, etc.

SAFETY INSTRUCTIONS FOR INGERSOLL-RAND LOADER BACKHOE AND ATTACHMENTS
SAFE OPERATION IS THE OPERATOR’S RESPONSIBILITY

Carefully follow the operating and maintenance instructions in this manual.

• The Ingersoll-Rand loader backhoe is highly maneuverable and compact. It is rugged and useful under a wide variety of conditions. This presents an operator with hazards associated with off-highway, rough terrain applications, common with Ingersoll-Rand loader backhoe usage.
• The Ingersoll-Rand loader backhoe has an internal combustion engine with resultant heat and exhaust. All exhaust gases can kill or cause illness, so use the loader backhoe with adequate ventilation. The loader backhoe has a spark arrestor exhaust system or muffler which is required for operation in certain areas.
• The dealer explains the capabilities and restrictions of the Ingersoll-Rand loader backhoe and attachments for each application. The dealer demonstrates the safe operation according to Ingersoll-Rand 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 a Rated Operating Capacity (some have restricted lift heights) and secure fastening to the Ingersoll-Rand loader backhoe. The user must check with the dealer, or Ingersoll-Rand literature, to determine safe loads of materials of specified densities for the loader backhoe-attachment combination.

The following publications and training materials provide information on the safe use and maintenance of the Ingersoll-Rand loader backhoe and attachments:

PLEASE NOTE:

• This is the same manual used by the dealers to diagnose and troubleshoot your vehicle
• You will be directed to the download page as soon as the purchase is completed. The whole payment and downloading process will take anywhere between 2-5 minutes
• Need any other service / repair / parts manual, please feel free to contact [email protected] . We still have 50,000 manuals unlisted
