HYDRAULICS DELIVER A REAL BREAKTHROUGH

Nothing equals the impact force of hydraulic-powered breakers. With the best power-to-weight ratio, higher blow energy, and a lower noise level than pneumatic breakers, hydraulic percussion tools are simply the best choice. 70-lb. class breakers, for instance, deliver roughly the same impact energy as most 90-lb. pneumatic breakers. Internal components are continually bathed in hydraulic oil, providing long-lasting performance with minimal maintenance requirements. And because the hydraulic system is totally enclosed, there’s no tool exhaust or oil atomization often found with gas-powered or pneumatic alternatives.

Compared to other options, hydraulic breakers offer

Higher impact than comparably sized alternative platforms
No tool exhaust
Quieter operation than pneumatic tools allows for use in sensitive areas
Hydraulic oil provides continuous lubrication of internal parts for longer service life
Modular, re-buildable design platform improves serviceability
Handles system back pressures up to 250 psi / 17 bar
Feathering ON/OFF valve to control speed and make initial tool placement easy

A general rule of thumb when sizing the appropriate breaker for your application is to use 10 pounds for each inch of material. A 40-pound breaker, for instance, is a good fit for 4-inch concrete. A 90-lb. breaker would be used to break 9-inch concrete.

FAQ's

How do I clean the Valve Cap Assembly?

Stanley suggest soaking the filter in light oil after each use then blow the filter out with compressed air from the inside out while removed from the breaker. If the filter does not appear to be clean after this cleaning, replace the entire valve cap assembly.

Where is the Valve Cap Assembly located?

The Valve Cap Assembly looks like a large nut and is located on top of the Handle Assembly.

Will my tool operate if I use a lower flow rate than what would be considered optimum for the tool to operate?

Yes, most tools have an optimal flow range, as long as the gallons per minute delivered to the tool is within this range the tool will work. However, please be award that the tool will run at a slower speed based on the flow rated delivered to the tool. Basically, the lower the gallons per minute the slower the tool will run.

Do any of the Stanley hydraulic tools ship full of hydraulic oil?

No, but the factory normally will leave a little fluid inside the tool to help lubricate the internal components during storage.
