13、1997 BSI 03-1999 1 1 Scope This International Standard sets forth, for guidance, a list of diagnostic instruments to check earth-moving machinery at the work-site. The main purpose of this International Standard is to ensure that earth-moving machines be designed with proper accessibility and necess
14、ary connections in order to make it possible to perform these checks in an easy way, using portable instruments. NOTE 1Service instruments use of which involves major machine disassemblies or which are more suitable for use in the workshop are purposely excluded from this list. NOTE 2Diagnostic chec
15、ks are intended to be carried out by qualified personnel. Relevant specifications and instructions should therefore be included, preferably in the service manual, rather than in the operators manual. This International Standard applies to crawler and wheel tractors, crawler and wheel loaders and hyd
16、raulic excavators, but can be easily extended to apply to other basic earth-moving machines such as graders, tractor scrapers and dumpers. 2 Types of checks, instruments and scales Table 1 specifies the corresponding instruments for each check. The letters inTable 1 have the following meanings: The
17、instrument specified for each type of check has been selected from among those most commonly used. Other more sophisticated devices or instruments, if any, can be used as alternatives. The instrument values or ranges presented in Table 1 are intended to be indicative only and may change with technol
