JCB HYDRAULIC BREAKERS (OPERATION MANUAL)

To operate the range of JCB hydraulic breakers efficiently and safely you must know the breaker and have the skill to use it. You must also be a competent operator of the machine supplying the breaker with hydraulic power. If you are a new operator, you should become trained in the skills of using a hydraulic breaker before trying to work with it.
It is assumed that personnel carrying out maintenance have at least a sound knowledge of workshop practice, safety procedures and general techniques associated with the repair of hydraulic equipment.
It is expected that components will be thoroughly cleaned and lubricated, where appropriate, also that any opened hose connections will be blanked to prevent entry of dirt and excessive loss of hydraulic fluid.
