Section 1 - General Information Introduction About this Manual 1-1 1-1 9803/9360-4 Introduction About this Manual Machine Model and Serial Number This manual provides information for the following model(s) in the JCB machine range: Using the Service Manual T11-004 This publication is designed for the benefit of JCB Distributor Service Engineers who are receiving, or have received, training by JCB Technical Training Department. These personnel should have a sound knowledge of workshop practice, safety procedures, and general techniques associated with the maintenance and repair of hydraulic earthmoving equipment. The illustrations in this publication are for guidance only. Where the machines differ, the text and/or the illustration will specify. General warnings in Section 2 are repeated throughout the manual, as well as specific warnings. Read all safety statements regularly, so you do not forget them. Renewal of oil seals, gaskets, etc., and any component showing obvious signs of wear or damage is expected as a matter of course. It is expected that components will be cleaned and lubricated where appropriate, and that any opened hose or pipe connections will be blanked to prevent excessive loss of hydraulic fluid and ingress of dirt. Where a torque setting is given as a single figure it may be varied by plus or minus 3%. Torque figures indicated are for dry threads, hence for lubricated threads may be reduced by one third. The manufacturer's policy is one of continuous improvement. The right to change the specification of the machine without notice is reserved. No responsibility will be accepted for discrepancies which may occur between specifications of the machine and the descriptions contained in this publication. Finally, please remember above all else safety must come first! Section Numbering T11-005 The manual is compiled in sections, the first three are numbered and contain information as follows: The remaining sections are alphabetically coded and deal with Dismantling, Overhaul etc. of specific components, for example: Section contents, technical data, circuit descriptions, operation descriptions etc. are inserted at the beginning of each alphabetically coded section.

Section 1 - General Information Identifying Your Machine Identification Plates 1-3 1-3 9803/9360-4 Identifying Your Machine Identification Plates Machine Identification Plate Your machine has an identification plate mounted as shown. The Product Identification Number (PIN), weight, engine power, year of manufacture and serial number of the machine are shown on the plate. Note: The machine model and build specification is indicated by the PIN. Refer to Typical Product Identification Number (PIN). If the engine is replaced by a new one, the serial number on the identification plate will be wrong. Either get a replacement identification plate from your JCB Dealer or simply remove the old number. This will prevent the wrong unit number being quoted when replacement parts are ordered. The machine and engine serial numbers can help identify exactly the type of equipment you have. Fig 1.
