Breaking – Do’s and Don’ts

To ensure long life the JCB LARGE HYDRAULIC BREAKER requires correct set up and size the hammer matched for the job. “If a small breaker is used on a job that requires a much larger breaker, its life will be shortened. by forcing the breaker to do more than it was designed to do, “A large breaker can do a smaller job or break smaller material however the operator may not have the control.” The hydraulic systems must also be set to match the particular hammer used. Hammers are designed to run within a defined range of hydraulic pressures and flows.

Operating out side these limits will either shorten its life or result in poor performance
