Example:
Stabilized Temperature
Ambient Temperature
Heat Rise
The normal operating temperature range of this circuit
will be the ambient temperature plus the heat rise, as
calculated above. Ensure that the operating temperature
range is lower than 180° F for optimum operation of the
attachment.
TROUBLESHOOTING
If adequate pump flow is available from the carrier
pumps but is not getting to the attachment, consult your
service representative and review the following:
• Attachment valves are not actuating. Review all
electrical connections that are part of the attachment
kit.
• Ensure proper voltage to the valves.
• Ensure the REG port of the valve is not blocked.
• Check to make sure the carriers main relief is set
to the manufacturers recommendation and that this
value is equal or greater than the attachment circuit
relief.
• If the valve will not turn off, check the drain (tank)
line of the valve to ensure that the pressure is 50
psi or less.
PRE-INSTALLATION INSTRUCTIONS
CARRIER SIZE
Check the Specifications section (page 10) of this
manual to determine correct carrier size, hydraulic flow
and pressure requirements.
If hydraulic pressure, hydraulic back-pressure, hydraulic
flow or excavator weight class are exceeded, the tool
warranty is void.
EXISTING EQUIPMENT HYDRAULICS
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. Confirm the pressure and flow of the hydraulic
system before connecting the MBF5. Spare spool
valves, dipper circuits, etc., are just a few examples of
easily accessible hydraulic circuits which could cause
problems for hydraulic tool usage.
TEST THE HYDRAULIC SYSTEM
3. Have your STANLEY dealer test the carrier hydraulic

system to make sure the system is operating at the
manufacturers specified capacity and pressure
ratings.
4. Be sure the fluid in the hydraulic system is clean.
5. Check the hydraulic filter. Replace the filter if dirty or
deteriorated.
6. 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 (page 10).
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 250 mm / 10 in. 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.
