WARNING
Stop the hydraulic system of the excavator.

9Blue Diamond® Attachments
2.5 Breaker Operation
The tool contact area must be visible to the
operator to ensure full contact.
Engine Speed
During the breaker inspection, the installer
determines the exact ratio of excavator engine
revs to the appropriate oil flow rate for the breaker.
This information MUST be communicated to the
operator.
Usage Instructions
The breaker can work in all the positions allowed
by the joints of the excavator boom, as long as it is
always pressed perpendicular to the surface of the
material to be demolished.
The operator must maintain the correct pressure to
the breaker. If the pressure is too low, the breaker
retains a part of the energy which will be released
to the excavator boom. The boom will then
undergo dangerous vibration and shaking.
If the pressure is too powerful, the structure of the
breaker can be compromised as well as the metal
plate and the tool.
Excavator Boom Extension
While the breaker is in operation, shorten the
distance between the excavator and breaker as
much as possible. Extend the cylinder piston rods
only partially (Items 1 and 2) [Figure 4].
Figure 4
Avoid Blank Firing
Ensure that the tool does not slip from the surface
[Figure 5]. If the tool is placed incorrectly or is held
weakly to the material, dangerous blank firing can
occur.
Figure 5
2. Operation
WARNING
• The operator MUST follow all manufacturer’s
instructions.
• Do not use without the tool retaining pin.
• Use only tools authorized by the manufacturer.
WARNING
It is absolutely necessary that the operator
respects the ratio of revs to oil flow rate.
Working with a higher or lower number of revs can
cause serious damage to the a hammer.
WARNING
The correct position must be kept during the
whole phase of feed of the tool, operating on the
controls of the bucket and the excavator boom.

2.5 Breaker Operation Cont’d
Usage Instructions Cont’d
Operation Near/In Water or Wet Conditions
The breaker cannot operate in water if the water
level exceeds the tool stroke [Figure 6], unless the
breaker is set up for it.
If in doubt, contact Blue Diamond® Product Support.
Figure 6
2.6 Breaker Operations to
Avoid
Blank Firing
Avoid blank firing the breaker. Blank firing causes
early wear and chipping to the tool retainer pin
and the tool itself. Chips from the tool can cause
serious damage. Blank firing can cause the tool to
break prematurely.
Do not Use as a Lever
The tool cannot be used as a lever to move rocks
or other debris. This operation can cause the tool
to break or seize especially if this is done while the
breaker is working [Figure 7].
Figure 7
Removing Large Rocks
Do not remove or pull large rocks
or boulders using the breaker
frame. This can cause some parts
to become unwelded and the plate
can warp [Figure 8].
Figure 8
Stagnant Movement
Do not hammer in the same
location without moving for
more than 30 seconds. In the
event of a very hard surface,
it will be necessary to change
position very often until softer
ground is found [Figure 9].
Preheat Oil
Never forget to preheat the oil before beginning
operation, especially when there are low outdoor
temperatures. It is a good practice to operate the
translation control and those of the excavator
boom’s central piston to the end of the stroke
until the oil reaches a temperature of 77–86°F
(20–30°C).

3.1 Tool Replacement
Removing the Tool
Position the breaker vertically, touching the ground
[Figure 10]. Lift it up from the ground a few inches
so that the excavator boom supports the breaker’s
weight, but the tool is still making contact with the
ground.
Figure 10
Press the retainer pin with a screwdriver so that
the prominent part returns into its seat (Operation
1) [Figure 11].
With a second screwdriver, press on the retainer
pin for the tool and push it out almost completely
(Operation 2) [Figure 11].
Figure 11
Remove the retainer pin with gloved hands and
place the pin on the ground.
Enter the Operator’s position (see section 2.1
Entering and Exiting the Prime Mover on page 7)
and unblock the hydraulic system.
Lift the breaker vertically until the damaged tool
slips o.
Coupling a New Tool
Place the breaker horizontally on the ground with
the tool lined up in front of it.
Grease the part that must fit into the guide well.
Fit the tool end (the one with the retainer flat/flats)
into the guide manually. Two operators may be
necessary if the tool weight exceeds 65 lbs. Check
the weight in the technical specifications.
Then, push from the other side and fit the tool
completely into the guide [Figure 12]. Rotate the
tool so that its milled side sets parallel to the pin
guide. Insert the tool retainer pin.

3.2 Tool Types and Uses
Tools are dierent based on the dierent shapes
of their terminal parts. There are various types
of tools capable of meeting the requirements of
every kind of application.
Blunt Terminal Tool
The Blunt Terminal Tool (Item A) [Figure 13] is
suitable for stone crushing. These are normally
used on small and medium breakers.
Chisel Terminal Tool
The Chisel Terminal Tool (Item B) [Figure 13] is used
for mining in general. It is essential in demolitions
where a high cutting capacity is required such as
walls, floors, reinforced concrete buildings, fixed
section diggings, and stone excavations.
Not suitable for stone crushing. This tool covers
80% of the applications on small and large
breakers.
Pyramidal Terminal Tool
The Pyramidal Terminal Tool (Item C) [Figure 13] is
used similar to those of the Chisel Terminal Tool.
This tool is suitable for small breakers.
Cone-Shaped Terminal Tool
The Cone-Shaped Terminal Tool (Item D) [Figure
13] is suitable for the demolition of walls and non-
reinforced concrete structures, stones, and quite
soft materials. To be mounted on the whole range
of breakers.
Small Spade Terminal Tool & Asphalt-Cutter Tool
The Small Spade Terminal Tool (Item E) and
Asphalt-Cutter Tool (Item F) [Figure 13] is suitable
for tracing the lines marking the limits of the
diggings. To be mounted only on small and
medium breakers.

Figure 13

13Blue Diamond® Attachments
It is always essential to remove the connecting
hoses between the breaker and the excavator.
4.1 Cleaning
The breaker does not require particular care. The
only necessary precaution consists in preventing
dirt from entering hose connections.
4.2 Maintenance and
Inspection
The breaker requires some important maintenance
in order to work correctly and not break
prematurely.
Greasing
Remember to only use a grease that meets the
following requirements:
• Resistant to high loads
• Water resistant, anti-rust, anti-corrosive
• NLGI-2 Penetration
• Dripping point of 200 – 220°C
• Temperature of use until t=170–180°C
We recommend only using authorized grease for a
longer lifespan of the parts.
Inspection
4.3 Hydraulic System Checks
Hydraulic Oil Temperature
Make sure that the temperature during work does
not exceed 80°C.
Higher temperature can cause an irregular working
condition and the breaker could stop.
Hydraulic Oil Levels
It is absolutely necessary to pay attention to the
hydraulic oil level in the excavator tank. If oil is
under the lowest limit, the breaker can vibrate or
work irregularly.
It is important to check the rigid and flexible hoses
in order to find damage, crushing, or oil leaks.
4. Maintenance
IMPORTANT
Throughly clean the quick couplers before
making connections. Dirt can quickly damage the
hydraulic system.
WARNING
Never operate on the breaker or on the hydraulic
system when they are under pressure or at high
temperatures.
IMPORTANT
The breaker must be greased at minimum every
2 hours of operation. A proper quantity of grease
must be used.
ITEMS
PMake sure that there are no oil leakages
along the tool shank.
PMake sure that no cracks are evident on
the frame or on the linking bracket.

Blue Diamond® Attachments14
4.4 Weekly Maintenance
Chipping or Cracks on the Tool or Pin
Take the tool out in order to determine possible
chipping or cracks in the bush and on the surface
of the tool pin.
Marks indicate insucient lubrication, use of
unsuitable oil, or improper use of the breaker.
With the help of a sanding disk, polish the
trimmings that can be seen on the surface
between the tool and the tool retainer pin (Items B)
[Figure 14].
Figure 14
Retainer Pin Wear
Check the wear of the tool retainer pin; in case of
excessive wear, invert the assembly or replace it.
Tool Bushings Wear
Check the wear on the tool bushings. If the inside
diameter is larger than the value indicated in the
technical specifications, contact Blue Diamond®
Product Support for assistance changing the
bushes.
Breaker Bolt Loosening
At regular intervals, check the possible loosening
of bolts; particularly:
• The screws fixing the head/bracket
• The screws fixing the flanges/hose joints
4.5 Ending Operation and
Storage
Ending the Day’s Operation
End the work day with a hot breaker. During the
night, the breaker should driven vertically into the
ground. When the breaker is left in this position,
the condensed water is easily emptied through the
prominent part of the piston avoiding oxidation.
Long Term Storage
When the breaker is disconnected from the
excavator boom and is left in storage for a long
time, it is necessary to do the following:
• Remove the tool, push the piston (with a tube)
as high as possible, grease abundantly, and re-
install the tool.
This operation prevents the piston terminal
from rusting.
• The breaker must be stored in an enclosed
place sheltered from weather.

4. Maintenance
PROBLEM CAUSE SOLUTION
Frequency loss with heavy and
violent blows.
Very high back pressures on the return
line.
Check for blockages in the return line. Remove obstacle.
Check if the filters are partially or totally blocked. Remove block-
age.
Check if the taps are partially or totally blocked. Remove obstacles.
Even though the breaker is
lifted up, the tool does not slide
downward.
Insucient greasing or dirt has entered
between the bushing guides and the tool.
Take down the tool, check the bush, and eliminate the seizing
marks. Clean, grease, and re-install the tool.
The breaker suddenly stops
after four or five blows just after
touching the ground surface.
The piston is at the bottom of the automat-
ic brake and the tool is completely out.
The material is usually soft. The tool sticks out but does not go in
again. The breaker must be reloaded correctly and the load must
be kept constant. Improve operation by keeping the breaker as
vertical as possible while working.
Oil leaking from the hoses’
connection block. The O-Ring is damaged. Take down the block and change the seals.
Oil leaking from the hoses.
The rubber hose is damaged. Reinstall and replace the flexible rubber hose.
The rubber hose is installed incorrectly and
not correctly tightened. Reinstall the hose correctly with proper tightness.
The breaker stops after a few
blows even after being rein-
stalled.
Dirt entered the breaker through the hose
connections.
Take down the breaker; clean and replace the damaged compo-
nents.
Oil leaking from the tool. Seals are work out and there are marks on
the piston surface. Replace seals and any other damaged parts.
The breaker beats with a weak
penetration force and there are
too many vibrations on the high
pressure rubber hose.
The accumulator has lost the pre-charge or
the diaphragm is broken.
Restore the correct pressure.
The diaphragm may need to be replaced before restoring the
correct nitrogen pressure.
The breaker increases the
number of blows but the power
decreases.
The tool support seat (support ring) is worn
out. The piston shortens the stroke.
Make sure the tool support seat (support ring) is intact. Proceed as
follows:
1. Lay the breaker on the ground and trace a mark on the tool at
the level of the bush end.
2. Remove the tool and make sure that the value between the
mark and the plate end of the tool is lower or equivalent to
the one indicated in the technical specifications. If it is higher,
replace the support ring immediately.
