What's in it

The book is in two parts: electrical diagrams and hydraulic diagrams. They show how the circuits are connected, so an electrician or fitter can follow a fault from one end to the other without guessing.

Drawings for older shovels like the H185S are getting harder to find. If the shovel has been modified since 2005, check the drawings against the machine as you go.

Pair it with a shop manual for the operating values and procedures. This book shows the layout, not how to repair it.

Good to know

A diagram book doesn't tell you what a reading should be. That's in the shop manual. What it does is show exactly how the machine is connected, which is the part that takes longest to work out without drawings. Used together, the two books make fault finding much quicker. Diagrams are easiest to use printed large or zoomed in on a screen. Electricians often trace the circuit they're working on with a highlighter, then check each connector and wire along that path with a meter. Hydraulic drawings work the same way, from the pump through the valves to the cylinder or motor.
