EXISTING EQUIPMENT HYDRAULICS VS APPLICATION ATTACHING KITS
Using existing equipment hydraulic auxiliary systems for operating hydraulic tools could cause problems for the hydraulic tool and the hydraulic system if not set up properly. Simply plugging into the hydraulic system with- out confirming pressure and flow to the hydraulic tool is not a good practice. Spare spool valves, dipper circuits, etc., are just a few examples of easily accessible hy- draulic circuits which could prove to cause problems for hydraulic tool usage.
ATTACHING KITS adapt to existing hydraulic systems of many popular backhoes and excavators.
If your equipment does not contain an attaching kit, ask your Stanley dealer for information, installation, and pricing on a kit which matches your equipment needs.
TEST THE HYDRAULIC SYSTEM
1.Have your Stanley dealer test the excavator hydrau- lic system to make sure the system is operating at the manufacturers specified capacity and pressure ratings.
2.Be sure the fluid in the hydraulic system is clean.
3.Check the hydraulic filter. Replace the filter if dirty or deteriorated.
4.Have your Stanley dealer test the circuit to which the breaker will be connected to make sure that the circuit is supplying the specified flow and pressure rating for the breaker. See the SPECIFICATIONS section of this manual.
PRE-OPERATION
PREPARATION FOR OPERATION
NITROGEN CHARGE
The breaker has been properly charged with nitrogen at the factory and is ready to use (see pages 20 and 21) for charging information.
TOOL BIT LUBRICATION
Grease the top 250 mm/10 inches of the breaker tool bit before installing. During operation, the tool can be greased through the grease fitting. Grease as required.
Make sure the tool bit is against the tool stop by placing the tool bit against the ground and then put- ting down pressure on the breaker. SEE THE ILLUS-
TRATION BELOW AND ON THE FOLLOWING PAGE.

Figure 1. Greasing the Tool Bit Before Installation
NOTICE
Greasing the tool bit without down pressure on the tool will result in grease filling the space between the piston and the tool bit.
When the breaker is next activated, the piston will strike the grease at a speed that will cause the grease to apply great force against the seals and grease zerk resulting in damage to these components.
