SIZE
Check the Specications section of this manual to
determine correct carrier size, hydraulic ow and
pressure requirements.
WARNING
If hydraulic pressure, hydraulic back pressure,
hydraulic ow 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 conrming pressure and ow 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.
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 tting. 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.
10 inches/250 mm
Figure 1. Greasing the Top of the Tool Bit
TEST THE HYDRAULIC SYSTEM
1. Have your Stanley dealer test the carrier hydraulic
system to make sure the system is operating at
the manufacturers specied capacity and pressure
ratings.
2. Be sure the uid in the hydraulic system is ltered
to at least 10 micro-meters. (Particles found in uid
should not exceed 10 micro-meters in size.)
3. Check the hydraulic lter. Replace the lter 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 specied ow and pressure
rating for the breaker. See the Specications section
of this manual.
WARNING
Greasing the tool bit without down pressure on the
breaker results in grease lling 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.

SECURING THE TOOL BIT
1. The tool retainer is shipped installed in the breaker
(see parts illustration).
2. Drive out the tool retainer using a punch and
hammer.
3. Grease the top area of the tool bit as shown in
Figure 1.
4. Install the tool bit making sure the notch is aligned
with the lower body retainer pin hole.
5. Install the tool retainer.
2. With the carrier at idle and the breaker suspended
in the air or with minimal down pressure, turn
on the breaker to gradually warm up its internal
components.
3. When the hydraulic system and breaker are warm,
proceed with operation.
LONG TERM STORAGE
1. Remove the tool bit. Clean the tool stop and the
lower bushing. Thoroughly coat the surfaces of the
tool stop and the lower bushing with grease.
2. If hoses are attached to the breaker, install plugs
on the hose ends. If hoses are removed from the
breaker, install plugs on the hose ends and install
plugs in the breaker IN and OUT ports.
3. Store the breaker in a vertical position. Do not store
the breaker horizontally for extended periods.
OPERATING A BREAKER
PREPARATION FOR USE
Read the section in this manual titled Pre-Operation
Procedures before operating a breaker. Failure to follow
the preparation instructions can result in severe damage
to the breaker and carrier and void the warranties of
both.
POSITIONING THE CARRIER
SKIDSTEER LOADERS
With the breaker tool in place on the material to be
worked, position the skidsteer loader arms and the
breaker bracket so the breaker is almost vertical and the
front tires of the skidsteer are off of the ground.
Keep lowering the loader arms as the tool penetrates
the work material so the skidsteer weight stays on the
tool. The breaker is more efcient when adequate down
force is applied.
WARNING
Always wear eye protection when installing or
removing the tool retaining pin.
LOW TEMPERATURE WARM-UP
PROCEDURE
1. After starting the carrier, warm-up the hydraulic
system at engine idle until hydraulic lines are warm
to the touch.
10 ► MB656 User Manual
Apply down pressure.
Apply down force.
Break near the edge.
OPERATION
Figure 5. Excavator
Figure 3. Skidsteer Loader
BACKHOES
With the breaker tool in place on the material to be
worked, position the backhoe so the boom is halfway up
(45°) and the dipper holds the breaker almost vertical.
Lower the loader bucket until the weight is off the front
tires.
Figure 4. Backhoe
Apply down force to the boom/dipper until the rear of
the backhoe is raised off the ground. Rear tires and
stabilizers should be off the ground so the total rear
weight of the backhoe is on the breaker tool. The breaker
is more efcient when adequate down force is applied.
EXCAVATORS
With the breaker tool in place on the material to be
worked, position the excavator so the dipper is at
approximately 45° and the breaker is almost vertical.
The tracks of the excavator should be in line with the
boom and the breaker.
POSITIONING THE BREAKER TOOL ON
THE WORK MATERIAL
Position the tool bit near the edge of the work material,
not in the center or far from the edge. Position the tool
6–18 inches (depending on the material) from the edge.
Breaking off smaller pieces of rock or concrete usually
accomplishes more than trying to break larger pieces.
Figure 6. Position the Tool Bit
On at material or rock, the breaker should be vertical
or “curled” back slightly to direct the impact force
downward and toward the backhoe. This directs the
force back toward the edge of the work material. If the
tool is positioned in the center of the work, or too far from
the edge, the energy will be absorbed into the material
without cracking it. Do not run the breaker longer than
15–20 seconds. If breakout does not occur within this
time, move the breaker to another position.
