Gives a guide list of diagnostic instruments to check earth-moving machinery at the work site, to ensure that machines are designed with proper accessibility and necessary connections to perform these checks easily, using portable instruments. Does not include service instruments for major machine disassemblies or use in the workshop. Applies to crawler and wheel tractors, crawler and wheel loaders and hydraulic excavators, but can be easily extended to apply to other basic earth-moving machines.

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 necessary connections in order to make it possible to perform these checks in an easy way, using portable instruments.NOTES1 Service instruments whose utilization involves major machine disassemblies or which are more suitable for use in the workshop are purposely excluded from this list.2 Diagnostic checks 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 operator's manual.Field of applicationThis International Standard applies to crawler and wheel tractors, crawler and wheel loaders and hydraulicexcavators, but can be easily extended to apply to other basic earth-moving machines such as graders, tractor scrapers and dumpers.
