New Holland Mini Excavators E18SR  Service Manual_87677528A

TO THE READER :

This manual has been printed for a skilful engineer to supply the necessary technical information to carry out service operations on this machine. Carefully read this manual to obtain correct information regarding repair procedures.

COMPLETE SERVICE MANUAL:

The Service Manual consists of one volume: – E18SR Service Manual for “Mini Excavators” The Service Manual for “Mini Excavators” contains the necessary technical information to carry out maintenance and repair operations on the machine, the necessary tools to carry out maintenance operations, the information on service standards, the procedures for removal, installation, disassembly and reassembly.

HOW TO USE MAINTENANCE STANDARDS AND PRECAUTIONS:

•  For New Machine: This manual is to be used to check the actual performance and functions of the machine compared with the PERFORMANCE STANDARDS. At Specific Self-Inspection (as per LOCAL RULES); The maintenance standards are used to make them as the criteria to determine the time for reconditioning, adjustment and replacement.
• At Deterioration of Performance; This manual is of the criteria of safe and economical judgment whether the deterioration of performance on the machine would be caused by any faults or normal deterioration due to machine operation for a long period.
• For Replacement of Major Components; This manual is of the standard to determine the time for replacement to recover the performance of major components such as pump, etc.  Terminology  Standard Values: These are of the standard values to assemble and regulate a new machine.
• Where special notes are not given, these values are based on the machine with standard structure (the machine with standard attachments and shoes).  Standard Values for Repair: These are of the values at which the reconditioning is required.
• In order to ensure the performance and safety, it is strictly prohibited to use the machine with the parts and components being over the standard values.  Serviceability Limit: This is of the service limit for each part and component at which the reconditioning is impossible and they must be replaced to new ones.
• All the parts and components which are estimated to exceed the serviceability limit up to the next periodical inspection and maintenance, should be also replaced to new ones. The machine operation with the parts and components which have exceeded the serviceability limit, causes increase of troubles and down time of the machine, and also causes safety problems.
