STRUCTURE2
TIE ROD
Front head, cylinder and back head of breaker
body are tightly fixed with four tie rods.
BACK HEADGas charging valve is built in and the inside is
charged with N2 gas.
VALVE
Cylindrical control valve is built in the valve
housing and controls piston reciprocation.
CYLINDER
The cylinder is the heart of the breaker con-
taining hydraulic circuit for piston reciprocation.
ACCUMULATOR (GB11F / GB14F)
The accumulator compensates for pressure in
the hydraulic circuit and prevents pulsation. It is
not usually necessary to refill. Use N2 gas only.
PISTON
Kinetic energy of the piston is converted into
hammering energy after hitting the tool. The
hammering energy transmitted to the tool breaks
rocks.
FRONT HEAD
The front head supports the whole breaker.
Thrust ring and thrust bushing prevents shock
from the tool.
TOOL
The specially heat-treated tool is directly applied
to break rocks. It is in the form of a wedge, moil
point, blunt, cone and wide chisel appropriate to
the application. (optional)

WORKING PRINCIPLE3
T-SERIES
The relation between the area (A1) affecting the pressure from the upper chamber of the piston and the area
(A2) affecting the pressure from the lower chamber of the piston is A1> A2 and high pressure always applies to
A2. When A1 changes from high to low pressure or vice versa, Piston C2 reciprocates. Inside of back head is
charged with the high pressure gas and gas energy stored in the upstroke of the piston C2 effectively acts on
the piston C2 during the impact.
1. POWER STROKE
When piston C2 reaches top dead center, high pressure oil
from valve high-pressure port B3 applies to upper chamber
of the piston A1 to change the piston stroke from upstroke to
impact.
At this time the relation between the area(A3) affecting the
pressure from valve high pressure changes and the
area(A4) of the valve change chamber is A4 > A3. The high
pressure always applies to A4 and valve C4 remains in theupper position.
2. VALVE SHIFT
When cylinder low pressure port B1 is connected to cylinder
change port B2, the pressure in valve change port B4lowers. As force acting on valve C4 is the only pressure in
valve high pressure chamber A3, valve C4 starts lowering.
During the valve lowering stroke, valve high pressure port
B3 is closed and valve low pressure port B5 is opened to
the upper chamber of the piston A1 to lower the pressure in
the upper chamber of the piston A1.

Working principle
3. IMPACTWhen piston C2 reaches impact point, kinetic energy
obtained by piston C2 during the impact stroke is transmited
to the tool C3 for the impact energy required to break. At this
time, as high pressure applies only to the lower chamber of
the piston A2, piston C2 starts reversing. Further, as high
pressure applies only to the valve high pressure chamber
A3, valve C4 is remaining in the lower position.
4. UPSTROKE
When cylinder change port B2 is connected to cylinder
lower pressure port B1, high pressure oil applies to low
pressure outlet port and valve C4 start to the down position
A1 this time valve low pressure port B5 is closed and valve
high pressure B3 is opened the upper chamber of the piston
A1 to rise the pressure in the lower chamber of the piston
A1.

Operation of the hydraulic breaker requires installation of hydraulic pipe lines for exclusive use of the
hydraulic breaker. As hydraulic pipe lines vary depending on base machines, our service engineer must
first check the hydraulic pressure, oil capacity, pressure loss and other conditions of the base machine
before installing hydraulic pipe lines. Use only genuine parts in case of the need for replacement as
hydraulic pipe lines (hoses, pipes and fittings) are made of materials carefully selected in consideration
of durability.

within±10%
(40℃ cst)Adhesiveness
Less than 0.1
(%)Moisture
Less than 0.3
(mg KOH/g)Oxidizing Level
CAUSES AND EFFECTS WHEN EXCEEDS THE CRITERIA
Adhesiveness rarely decreases soley because of hydraulic
oil. Entry of different kind of oil may reduce the
adhesiveness which contributes to rising oil temperature,
wear and stretch of bearings and gears and malfunction of
hydraulic oil.
Use of a lubricating oil during long period of time under
high of a lubricating(higher than 60℃) will oxidize it.
Oxidizing level rises as ozidization proceeds. Sludge will
be produced during the process, leading to unsatisfactory
operation of the breaker, erosion of metals or
obsolescence of seal materials.
Moisture causes rust, wear and stretch. Moisture of 0.3%
gathers a considerable amount of rust and considerable
amount of rust moisture of 0.5% or more will cause
damage to the machine.
Hydraulic oil turns black as the breaker fails to display best performance. The old oil is assumed to be
contaminated when there is a visual difference between the old and new oil color and functions begin to
deteriorate when hydraulic oil turns darker than the new oil color(ASTM number) by more than two.

Operation
2. PROPER THRUST
1. To use the breaking force of a breaker effectively, a proper thrust has to be applied to the breaker. If the
thrust is insufficient, a hammering energy of the piston will not be efficiently used for breaking rocks. Thus,
the hammering force applies shock to the breaker body, arm and boom of the base machine, etc, resulting indamage to those parts.
2. On the other hand, if thrust is excessive and breaking is performed with the front of the base machine raised,
the machine may suddenly tilt forward at the moment the rock is broken and the breaker body may violently
hit against the rock resulting in damage.
3. If hammering is performed under such a condition, vibrations during hammering may also be transmitted to
the tracks, and therefore, hammering in such a manner should be avoided to also protect the tracks. Further,
during hammering, take care to always apply a thrust to the breaker. Do not hammer with no thrust applying.
1. OPERATION METHOD
1. When the tool is firmly stabilised on the rock and the
breaker has been pressed down, the operation valve can
be opened. While breaking, pressure must always be
applied longitudinally on the tool.
2. Close the operating valve immediately when cracks
appear on the rock or when the tool begins to move out of
the body of the breaker.
Pressing
During hammeringoperation, applypressuresuccessively.
Stop hammeringimmediately afterthe material isbroken.

3-4. Do not operate the breaker in water and mud.
- Do not operate the breaker with the
components other than the tool immersed in
water or mud. The piston or similar
components may be rusted to result in a
prematurely damaged breaker.
- In case of operation in/under the water, use
the under-water-type breaker
specially/independently ordered.

3-5. Operate carefully not to hit the excavator with the tool.
3-6. Keep optimum blows.
GB Hydraulic Breakers have a control valve for blows, please adjust blows with the control valve for blows
according to the field condition.
3-7. Working in high temperature conditions.
Check the oil temperature constantly to ensure it does not exceed 175℉(80℃). If higher temperatures aremeasured in the tank, an oil cooler must be fitted.
Operation
Don’t hit
Find trouble at an early stage!!
3-8. Do not move rocks.
Avoid moving rocks with the side of the
bracket. It is the major factor to bolts
installed on the bracket breaking. It will
also cause damage to the tool, boom and
arm.
8/19/2019 GB RockBreaker Manual
http://slidepdf.com/reader/full/gb-rockbreaker-manual 39/84
GB INDUSTRIES CO., LTD. | 37
Operation
3-9. Do not use tool as a lever.
If breaking rocks by using tool as a lever, the
bolts and tool may break.
3-10. Do not continue to hammer for more than one minute.
When rocks are not broken after more than one minute of hammering at the same point, change the place to
be hammered. Extended hammering at the same place causes the tool to wear out excessively.
3-11. Operate breaker at proper engine speed.
Break rocks at the specified engine speed.
Raising engine speed more than necessary
does not strengthen hammering force but
increases oil temperature to the detriment of
pistons and valves.
3-12. Do not allow the breaker to drop onto break a rock.
Dropping the breaker onto a rock will apply
excessive force to the breaker or the base
machine, causing damage to many parts of
the breaker and base machine.

Hammering with each base machine cylinder
moved to it’s stroke end(fully extended or
retracted) will do considerable damage to the
cylinder and each part of the base machine.
3-13. Do not hammer with base machine cylinders moved to the stroke end.
Lifting materials by hanging wire in the bracket
or tool not only causes damage to the breaker
but also is very dangerous when operating.
3-14. Do not lift things with the breaker.
Operation
3-15. Warm up base machine engine prior to operation.
Especially in winter, the base machine engine should be warmed up for five to ten minutes (about oil
temperature 30℃�40℃ /80℉�105℉) before breaker operation. Follow the base machine instruction book forwarming-up of the engine.
3-16. Do not touch the tool during hydraulic breaker operation.
During breaker operation, the breaker parts can reach high temperatures and thus should not be touched.

2. WEARING PARTS
2-1. The following items are considered as wearing parts.When damaged or worn, it is highly recommended to repair/replace these items.
① Tool
② Lower bush
③ Retainer pins
④ Hydraulic seals
⑤ Side bolt
⑥ Hydraulic hoses
2-2. Replace hydraulic seals every 600 hours of actual operation.
2-3. Tool retainerWhen each tool retainer is excessively deformed, it is difficult to replace the tool. Therefore, every 100 to
150 hours of operation, change the face of each tool retainer which comes in contact with the tool(The
two faces of each pin can be used).
If the tool you use is not a genuine part, we can not guarantee the performance of the breaker parts.
When replacing, check each part for wear, breakage, scoures, etc., especially, after removing burrs and
swelling on tool retainer and tool.
Replace tool after grinding the worn parts of lower bush and stop pin.
When changing tool pin direction, place pin with this surface on tool side.
Remove burrs and swellingwith grinder or the like.
Tool Retainer
2-4. Lower bushWear Limit of Tool and Lower Bush :
When the clearance between the tool and lower
bush becomes large, it is strongly recommended to
replace these to prevent other parts from wear.
Exceeding the wear limit dimension clearance may
damage other component parts, such as pistons
and cylinders.

3. OPERATIONAL PRESSURE
If the operating pressure of the breaker is regular and the pressure of the excavator itself is regular,
pressure does not need to be applied by attaching a relief valve to the high pressure line of the breaker.
Please get the help of the service department for applying pressure.
If the pressure is over regular pressure the breaker gets more impact which makes it a problem on the
breaker and the excavator.
4. OIL TEMPERATURE
The oil temperature will vary depending on operational conditions but it should range 50�80℃.
If it is over 80℃ it makes the accumulator rubber and o-ring’s life span shorter. Be cautious of the
following to avoid the rise in oil temperature.
1. Avoid continuous blowing at the same point over one minute.
2. Keep the indicated engine rotation.
The amount of oil needed in the breaker within the operational pressure is regular. In spite of more
engine rotation the blow frequency does not increase, rather the oil flows out by the relief valve. Thus
oil temperature will rise and the continued ratio becomes high.
NB : Indicated Engine Rotation
While hammering the breaker, if the engine rotation increases to some degree, it ceases to increase.
“This stage of rotation is the indicated engine rotation.”
3. Keep the cooler clean.
Keep the cooler clean to avoid falling a cooling effect.
5. OIL LEAKAGE
Check for oil leakages periodically. Minimum oil leakage, out of drain plug and between tool and tool
holder, should be disregarded as it helps keep the tool greased.
In cases of a lot of leakage check and replace the packings. Apply the working oil to the work-ing
packing, o-ring, gas-seal, dust seal and packing groove.
Applying grease(recommend cylinder grease) to o-ring is especially effective.
WHEN REPLACING THE PACKINGS THE FOLLOWING SHOULD BE INSPECTED.
1. Check if there are any scratches on the packings. Check that they are well pressed and not pushed
out.
2. Be cautious of dirt of flow.
3. If the working packing gets damaged, check the packing and stroke piston.
4. And also check if the dust seal has been pushed out or wrongly connected or if there are any
scratches in the cylinder.
5. When the working packing and gas-seal is damaged oil will leak out.
Replace each packing and o-ring. Contact your local service dealer for assistance.
