NOTE:
When choosing hydraulic uid, the expected oil temperature extremes that will be experienced in service determine the
most suitable temperature viscosity characteristics. Hydraulic uids with a viscosity index over 140 will meet the requirements
The recommended hose size is .500 inch/12 mm ID up
to 50 ft/15 m long and .625 inch/16 mm ID minimum up
to 100 ft/30 m.
PRE-OPERATION PROCEDURES
CHECK POWER SOURCE
1. Using a calibrated owmeter and pressure gauge,
check that the hydraulic power source develops a
ow of 7–9 gpm/26–34 lpm at 2000 psi/140 bar or
5–6 gpm /18–22 lpm at 1500–2000 psi /105–140
bar.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2250 psi/155 bar
maximum.
INSTALL TOOL BIT
1. Rotate the latch on the breaker foot downward
(pointing away from the tool).
2. Insert the tool bit into the foot and pull the latch up to
lock the tool bit in place.
CONNECT HOSES
1. Wipe all hose couplers with a clean, lint-free cloth
before making connections.
2. Connect the hoses from the hydraulic power source
to the tool ttings or quick disconnects. It is a good
practice to connect return hoses rst and discon-
nect them last to minimize or avoid trapped pressure
within the tool.
3. Observe ow indicators stamped on hose couplers
to ensure that uid ow is in the proper direction.
The female coupler on the tool hose is the inlet coupler.
4. Move the hydraulic circuit control valve to the ON
position to operate the tool.
NOTE:
If uncoupled hoses are left in the sun, pressure in-
crease within the hoses may make them difcult to
connect. When possible, connect the free ends of
the hoses together.
NOTE:
Partially depressing the trigger allows the tool to run
at slow speed. Slow-speed operation permits easier
starting of the tool bit into the work surface.
5. To start, break an opening (hole) in the center of the
surface. After making a hole, break portions of the
material into the original opening. For best productivity, the breaking should be done around the original hole.
The size of the broken material will vary with the
strength and thickness of the base material and the
amount of any reinforcement wire or rebar.
Harder material or more reinforcing wire or rebar will
require taking smaller bites. To determine the most
effective bite, start with 2 in./50 mm or smaller bites.
Bites can then be gradually increased until the broken piece becomes too large, requiring increased
time to break off the piece.
Sticking of the tool bit occurs when too large a bite is
being taken and the tool bit hammers into the material without the material fracturing. This causes the
tool bit to become trapped in the surrounding material.
COLD WEATHER OPERATION
If the breaker is to be used during cold weather, preheat
the hydraulic uid at low engine speed. When using the
normally recommended uid, uid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or breaker can result
from use with uid that is too viscous or thick.
OPERATION PROCEDURES
1. Observe all safety precautions.
2. Install the appropriate tool bit for the job.
3. Place the bit rmly on the surface to be broken.
4. Squeeze the trigger to start the breaker. Adequate
down pressure is very important. When the tool bit
breaks through the obstruction or becomes bound,
release the trigger and reposition the tool bit.

NOTICE
TOOL PROTECTION & CARE
In addition to the Safety Precautions found in
this manual, observe the following for equipment
protection and care.
• Make sure all couplers are wiped clean before connection.
• The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydraulic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from
damage or pilferage.
• Make sure the circuit PRESSURE hose (with male
quick disconnect) is connected to the IN port. The
circuit RETURN hose (with female quick disconnect)
is connected to the opposite port. Do not reverse cir-
cuit ow. This can cause damage to internal seals.
• Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a minimum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow and pressure. See
Specications in this manual for correct ow rate
and pressure rating. Rapid failure of the internal
seals may result.
• Always keep critical tool markings, such as warning
stickers and tags legible.
• Do not force a small breaker to do the job of a large
breaker.
• Keep tool bit sharp for maximum breaker performance. Make sure that tool bits are not chipped or
rounded on the striking end.
• Never operate a breaker without a tool bit or without
holding it against the work surface. This puts excessive strain on the breaker foot.
• Tool repair should be performed by experienced
personnel only.
• Make certain that the recommended relief valves
are installed in the pressure side of the system.
• Do not use the tool for applications for which it was
not intended.

CHARGING THE ACCUMULATOR
ACCUMULATOR TESTING
PROCEDURE
To check or charge the accumulator the following equipment is required:
• 31254 Charge Kit: which includes the following.
–Accumulator Tester (Part Number 02835).
–Charging Assembly (P/N 15304: includes a liq-
uid lled gauge with snub valve, hose and ttings).
• NITROGEN bottle with an 800 psi/55 bar minimum
charge. (Not included in 31254 kit)
The breaker contains nitrogen under pressure.
1.
Remove the plug from the handle or handle pivot.
2. Holding the chuck end of Accumulator Tester
(P/N 02835) turn the gauge fully counterclockwise to
ensure that the stem inside the chuck is completely
retracted.
3. Thread the tester onto the accumulator charging valve. Do not advance the gauge-end into the
chuck-end. Turn as a unit. Seat the chuck on the
accumulator charging valve and hand tighten only.
4. Advance the valve stem of the tester by turning the
gauge-end clockwise until a pressure is read on the
gauge (charge pressure should be 500–700 psi/34–
48 bar).
5. If pressure is OK unscrew the gauge-end from the
chuck to retract the stem, then unscrew the entire
tester assembly from the accumulator charging
valve. If pressure is low, charge the accumulator as
described in the following section.
6. Install the plug.
ACCUMULATOR CHARGING
1. Perform Steps 1 through 4 of the Accumulator Testing procedure.
2. Connect the chuck of the charging assembly to the
charging valve on the accumulator tester or, if preferred, remove the tester from the charging valve
and connect the charging assembly chuck directly
to the charging valve.
3. Adjust the snub valve to a charging pressure of
600 psi/42 bar. Note: While watching the pressure
gauge, open snub valve slowly until it reaches the
proper charge pressure (600–700 psi).
NOTE:
It may be necessary to set the gauge at 650–700
psi/45–48 bar to overcome any pressure drop
through the charging system.
4. When the accumulator is fully charged close the
snub valve on the charging assembly hose and remove the charging assembly chuck from the accumulator tester or tool charging valve.
5. If the accumulator tester has been used, be sure to
turn the gauge-end fully counterclockwise before removing the tester from the charging valve of the tool.
Install the valve cap.
