To ensure that the JCB hydraulic breakers (HM series) work efficiently and safely, they must be maintained and maintained regularly.

This guide is designed to give you a good understanding of how JCB hydraulic breakers work and provide detailed information about their maintenance.

This service guide contains only more specialized service information regarding maintenance aspects of breakers or individual component under consideration.
Therefore, general safety information and general techniques related to the repair of hydraulic equipment are not clarified in this manual, since it is assumed that the maintenance workers have at least superficial knowledge of these indicators.

So, we recommend that you carefully study the “Contents” of this manual for the screenshots and make sure that the information you need is present before purchasing.

Paying for the purchase, you immediately get access to download the file containing this manual. The manual is presented in the form of a PDF document, which will greatly simplify working with it. You can print a book and store it directly near the equipment.
