3 Transportation and installation
The personnel in charge of transportation and installation of the
equipment must be acquainted with the following instructions.
Pay careful attention to the weight of the hammer.
3.1 Transport
Always move with care: each inappropriate movement can be very
dangerous.
Do not pass or stop under the hammer when it is lifted up.
Check in the technical specifications, the
total weight of the hammer, that is together
with the adpating plate and the tool already
mounted.
In order to move the hammer safely, when
it is not coupled to the excavator, it is
necessary to have a suitable and safe
lifting system (as showed in the picture on
the right).
Always use means of transport and lifting,
suitable to the weight of the hammer.

3.2 Coupling on and Uncoupling from the excavator
3.2.1 Coupling
1) Place the hammer horizontally with its axe parallel to the excavator boom on the ground in
a stable position.
2) Remove the clamps holding the bucket and take the bucket away.
- Stop the hydraulic system of the excavator.
- Take the caps out of the system and in case they have no taps, collect the hydraulic oil in a
container, then fix the hoses connecting the hammer to the system (see scheme “Hammer
hoses connection” – par. 2.6) and open the oil taps if present.
- stock away the caps of the flexible hoses, which will be used again during the next
uncoupling of the hammer.
3.2.2. Uncoupling
- Place the hammer horizontally on the ground in a safe area.
- Stall the hydraulic system of the excavator.
- Close the hoses' flow if possible.
- Disconnect the hoses and close up the ends of the flexible hoses in order to prevent oil
leaking and dirt intake.
- Remove the connecting rod pin.
- Remove the excavator boom pin.
- After unblocking the hydraulic system, take the excavator boom out of the adapting plate.
Insert the boom end in the middle of the
adapting plate.
- Line up the hole of the excavator boom
with the equivalent one on the adapting
plate, insert the first pin and fix its
clamps.
- Line up the hole of the connecting rod
with the second hole on the adpating
plate, insert the second pin and fix well
its clamp.

4 Use of the hammer
The operator must follow the manufacturer’s instructions.
It is forbidden to use the hammer without the retainer pin for tool.
Use only tools authorised by the manufacturer.
The hammer must be in an open area so that, when it begins to hit, the tool is with no doubt
pressed against the surface of the material.
Engine speed
During the inspection of the hammer, the installer determinates the exact number of revs of
the excavator engine to which corresponds the appropriate oil flow rate for the hammer.
It is absolutely necessary that the operator respects these datas.
Working with a higher or lower number of revs can cause serious damages to the
hammer.
4.1 Instruction for use
The hammer can work in all the positions allowed by the joints of the excavator boom, as
long as it is always pressed perpendicularly against the surface of the material to be
demolished.
The operator must release the correct load pressure on the hydraulic pipe line to the
hammer: if it is too low, it retains a part of the energy which will be released to the excavator
boom that will eventually undergo dangerous vibrations and shakings.
If it is too powerful instead, it can endanger the structure of the hammer, of the metal plate
and the tool.
The correct position must be kept during the whole phase of feed of the
tool, operating on the controls of the bucket and the forearm.
USE OF THE HAMMER

Nederland B.V.

The hammer cannot work into the water if its level exceeds the tool stroke (see picture
down under), unless it is specifically made for this purpose.
In case of doubt contact the manufacturer.
Moreover, while the hammer is
working, we advice to shorten the
distance between excavator and
hammer as much as possible and to
remove the cylinder piston rods only
partially (C-D strokes never completely
out).
Make sure that the tool does not slip
from the surface (see picture). If the
tool is placed wrongly or holds weakly
on the material, dangerous blank
firing can occur.

4.2 Operations to be avoided
If you insist on the same spot for a long time, the drill can swell up, the tool can seize
and the oil can become overheated.
Avoid that the hammer delivers blank firings. They
cause early weariness and chippings to the retainer
pin for tool and to the tool itself, which scraps can
provoke serious damages. Moreover, due to these
blank firings, the tool will break very soon.
The tool cannot be used as a lever to move rocks or
debris: this operation can cause the seizing or
breaking of the tool, mainly if it is carried out while the
hammer is working.
Do not remove big rocks with the help of the hammer
frame: some parts can unweld and the plate can
warp.
Do not hammer on the same spot for more than thirty
seconds. In case of a very hard surface, it is
necessary to change position very often until you find
a softer ground.
Never forget to pre-heat the oil before beginning
to work: particularly in case of low outdoor
temperatures, it is a good practice to operate the
translation control and those of the central piston
of the excavator boom to the end of the stroke,
until the oil reaches a temperature of 25-30°C.

OPERATION 2
OPERATION 1
4.3 Replacement of the tool
Coupling of a new tool
Fit the tool end (the one having the retainer flat/flats) into the guide, manually.
Two operators can be necessary if the weight is more than 30 kgs (check the weight
with the technical specifications).
Then push from the other side and fit the tool completely into the guide. Rotate it so that its
milled side sets parallel to the pin guide. Insert the retainer pin for tool.
Before replacing the tool, it is necessary to wear gloves because it overheats
during the use.
Place the hammer vertically, touching
the ground and lift it up from the ground
of a few centimetres so that the boom
of the excavator supports the weight of
the hammer, but with the tool is still
touching on the ground.
Go down from the excavator, after blocking the hydraulic system.
Check the weight of the pin in the technical specifications.
Press the retainer pin with a lever so that the prominent
part returns into its seat (1
st
operation).
With a second lever press on the retainer pin for tool
and push it out, almost completely (2
nd
operation).
-Catch on the prominent part with your gloves
and place the pin on the ground.
-Get on the excavator again and unblock the
hydraulic system.
-Lift the hammer vertically until the damaged tool
slips off.
Place the hammer horizontally on the ground
and the tool lined up before it.
Grease well the part that must get into the
guide.

types of tools capable of meeting the requirements of every kind of application.
Flat terminal tool (ref. A)
It is suitable for stoke crushing.
Normally used on small and medium hammers.
Pyramidal terminal tool (ref. C)
The use is similar to the one described above. To be mounted on small hammers.
Cone-shaped terminal tool (ref. D)
Suitable for the demolition of walls and non-reinforced concrete structures, for stones and
quite soft materials. To be mounted on the whole range of hammers.
Small spade terminal tool (ref. E) or asphalt-cutter tool (ref. F)
Suitable for tracing the lines marking the limits of the diggings. To be mounted only on small
and medium hammers.
Chisel terminal tool (ref. B)
Used for mining in general. It is
essential in demolitions where a high
cutting capacity is required: for
example walls, floors and reinforced
concrete buildings, fixed section
diggings and excavations in stone.
Not suitable for stone crushing.
It covers 80% of the applications on
small and big hammers.

5 Cleaning, maintenance and checks
5.1 Cleaning
The hammer does not require particular care. The only precaution to take, consists in preventing
the dirt from entering through the hose connections, which must be rigorously closed before any
operation of assembly or disassembly.
5.1.1 Maintenance and daily checks
The machine needs some important maintenance, in order to work correctly and for a long time.
Greasing
This operation must be done at least every two hours, introducing an appropriate quantity of
grease.
Remember to use a type of grease, which must be:
- resistant to high loads.
- water resistant, anti-rust, anti-corrosive.
Have:
- NLGI-2 penetration
- Dripping point = 200-220 C°
- Temperature of use until t=170-180 C°
It is recommended to use possibly only Socomec grease for a longer life of the parts.
Other checks to be made on the hammer
- Make sure that there are no oil leakages along the tool sank.
- Make sure that no cracks are evident on the frame or on the linking bracket.
5.1.2 Checks to be made on the hydraulic system
Temperature of the hydraulic oil in the tank
Make sure that the temperature, during the work, does not exceed 80°C.
Higher temperature can cause an irregular working condition and also the stopping of the hammer.
Level of the hydraulic oil in the tank
It is absolutely necessary to pay attention to the hydraulic oil level of the excavator tank. In case it
is under the lowest limit, the hammer can vibrate or work irregularly.
It is important to check the rigid and flexible hoses in order to find out eventual damages, crushing
or oil leaking.
Never operate on the hammer or on the hydraulic system, when they are under
pressure or at high temperatures.
It is always essential to remove the connecting hoses between the hammer and the
excavator.

5.2 Weekly maintenance
Check on the loosening of the hammer bolts.
It is advisable to check, at regular intervals, possible loosening of the bolts and particularly:
-The screws fixing the head/bracket.
-The screws fixing the flanges/hose joints.
5.2.1 Machine stop
a) Take down the tool in order to determinate possible
chippings or cracks in the bush and on the surfaces of
the pin for tool.
These marks are proof of insufficient lubrication, use of
unsuitable oil or improper use of the hammer.
With the help of a sanding disk, polish the trimmings that can
be seen on the surface between the tool and the retainer pin
for tool (see points B in the picture).
b) Check the wear of the retainer pin for tool; in the case of
excessive wear, invert the assembly or change it.
c) Check the wear of the tool bushings; if the inside diameter
is bigger than the value indicated in the technical
specifications, contact the technical assistance to change the
bushes.
Stop at the end of a work with a hot hammer
During the night, drive the hammer vertically into the ground,
so that the condensed water can easily be emptied through
the prominent part of the piston, thus avoiding oxidation.
Long term stop
When the hammer is disconnected from the excavator boom
and is left standstill for a long time, it is necessary to:
Remove the tool, push the piston (with a tube) as higher as
possible, grease abundantly and re-install the tool.
This operation prevents the piston terminal from rusting.
Keep the hammer in a close place sheltered from bad
weather.
