PRE-INSTALLATION INSTRUCTIONS
SKIDSTEER, BACKHOE OR EXCAVATOR
SIZE
Check the Specifications section of this manual to
determine correct carrier size, hydraulic flow and
pressure requirements.
WARNING
If hydraulic pressure, hydraulic back pressure,
hydraulic flow or carrier weight class are exceeded,
the tool warranty is void.
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
without 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
hydraulic circuits which could prove to cause problems
for hydraulic tool usage.
Stanley Hydraulic Tools has, for many years, developed
ATTACHING KITS for adapting to existing hydraulic
systems of many popular carriers.
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 carrier hydraulic
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 filtered
to at least 10 micro-meters. (Particles found in fluid
should not exceed 10 micro-meters in size.)
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 PROCEDURES
NITROGEN CHARGE
The breaker has been properly charged with nitrogen at
the factory and is ready to use.
TOOL BIT LUBRICATION
Grease the top 10 in. / 250 mm of the breaker tool
bit before installing. During operation, the tool can be
greased through the grease fitting. Grease is required.
Make sure the tool bit is against the piston by placing
the tool bit against the ground and then putting down
pressure on the breaker. See the illustrations below.

WARNING
Greasing the tool bit without down pressure on the
breaker results 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
which will pressurize the grease resulting in seal and
grease zerk failure.
