HOSE TYPES
The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-
draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
Stanley Hydraulic Tools. They are:
Certified non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic fiber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certified non-
conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforce-
ment, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near
electrical conductors.
Fabric-braided (not certified or labeled non-conductive) — constructed of thermoplastic or synthetic rubber in-
ner tube, synthetic fiber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certified non-conductive and must never be used near electrical conductors.
HOSE SAFETY TAGS
To help ensure your safety, the following DANGER tags are attached to all hose purchased from Stanley Hydraulic
Tools. DO NOT REMOVE THESE TAGS.

OPERATION
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.
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.
PRE-OPERATION PROCEDURES
CHECK POWER SOURCE
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 produc-
tivity, the breaking should be done around the origi-
nal hole.
1. Using a calibrated flowmeter and pressure gauge,
check that the hydraulic power source develops a
flow 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.
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.
2. Make certain the hydraulic power source is equipped
with a relief valve set to open at 2250 psi/155 bar
maximum.
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.
INSTALL TOOL BIT
1. Rotate the latch on the breaker foot downward
(pointing away from the tool).
Bites can then be gradually increased until the bro-
ken piece becomes too large, requiring increased
time to break off the piece.
2. Insert the tool bit into the foot and pull the latch up to
lock the tool bit in place.
Sticking of the tool bit occurs when too large a bite is
being taken and the tool bit hammers into the mate-
rial without the material fracturing. This causes the
tool bit to become trapped in the surrounding mate-
rial.
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 fittings or quick disconnects. It is a good
practice to connect return hoses first and discon-
nect them last to minimize or avoid trapped pressure
within the tool.
COLD WEATHER OPERATION
If the breaker is to be used during cold weather, preheat
the hydraulic fluid at low engine speed. When using the
normally recommended fluid, fluid temperature should
be at or above 50 °F/10 °C (400 ssu/82 centistokes) be-
fore use.
3. Observe flow indicators stamped on hose couplers
to ensure that fluid flow is in the proper direction.
The female coupler on the tool hose is the inlet cou-
pler.
Damage to the hydraulic system or breaker can result
from use with fluid that is too viscous or thick.
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 difficult to
connect. When possible, connect the free ends of
the hoses together.
OPERATION PROCEDURES
1. Observe all safety precautions.
2. Install the appropriate tool bit for the job.
3. Place the bit firmly 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.

TOOL PROTECTION & CARE
NOTICE
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 con-
nection.
•
•
Do not force a small breaker to do the job of a large
breaker.
The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydrau-
lic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hy-
draulic system.
Keep tool bit sharp for maximum breaker perfor-
mance. 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 exces-
sive strain on the breaker foot.
•
•
Always store the tool in a clean dry space, safe from
damage or pilferage.
•
•
•
Tool repair should be performed by experienced
personnel only.
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 flow. This can cause damage to internal seals.
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.
•
•
•
Always replace hoses, couplings and other parts
with replacement parts recommended by Stanley
Hydraulic Tools. Supply hoses must have a mini-
mum working pressure rating of 2500 psi/172 bar.
Do not exceed the rated flow and pressure. See
Specifications in this manual for correct flow rate
and pressure rating. Rapid failure of the internal
seals may result.
Always keep critical tool markings, such as warning
stickers and tags legible.

CHARGING THE ACCUMULATOR
5. If pressure is OK unscrew the gauge-end from the
ACCUMULATOR TESTING
PROCEDURE
To check or charge the accumulator the following equip-
ment is required:
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.
•
31254 Charge Kit: which includes the following.
6. Install the plug.
–
–
Accumulator Tester (Part Number 02835).
Charging Assembly (P/N 15304: includes a liq-
uid filled gauge with snub valve, hose and fit-
tings).
ACCUMULATOR CHARGING
1. Perform Steps 1 through 4 of the Accumulator Test-
ing procedure.
2. Connect the chuck of the charging assembly to the
charging valve on the accumulator tester or, if pre-
ferred, remove the tester from the charging valve
and connect the charging assembly chuck directly
to the charging valve.
•
NITROGEN bottle with an 800 psi/55 bar minimum
charge. (Not included in 31254 kit)
CAUTION
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).
The breaker contains nitrogen under pressure.
1. Remove the plug from the handle or handle pivot.
NOTE:
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.
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 re-
move the charging assembly chuck from the accu-
mulator tester or tool charging valve.
3. Thread the tester onto the accumulator charg-
ing 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.
5. If the accumulator tester has been used, be sure to
turn the gauge-end fully counterclockwise before re-
moving the tester from the charging valve of the tool.
Install the valve cap.
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).
