1.1 Basic Safety Information
WARNING!
The following instructions are those that should ALWAYS be observed in operation of
construction equipment.
Know yourself
Operators and service personnel must wear appropriate safety
equipment, including hearing protection, respirator, hardhat, safety
shoes, eye protection, heavy gloves etc, as required.
Note: The wearing of loose clothing or any accessories such as neckties
,
scarves, untied shoe laces, rings, wrist watches or long hair could cause
personal injury or death.
Always use the proper tools for inspection or maintenance work, which
must only be carried out after ensuring that the equipment has been
stopped completely, and it is placed suitably in a safe place.
Figure 1
Know your equipment
Before installation or operation of the hammer, the operator and
maintenance personnel must read and understand the safety messages
,
operation manual and service instructions.
Only the operator who has been trained and qualified to operate the
carrier and hammer should do so. Be skilled and knowledgeable in all
operational and technical aspects of the carrier and hammer.
Figure 2
Know the work site
Before operating the hammer, check the area of work site for any
unusual conditions that could be dangerous,
and prepare the appropriate
warnings for safe work
ing. Be careful, particularly when working in the
vicinity of electric power lines, gas pipes or other buried services.
Pay particular attention to other workers, bystanders and other
machinery that may pass by near to the work site. Immediately stop
operation of the hammer if personnel enter the danger area.
Figure 3

- 8 -
Know the rules
Everybody who operates or maintains the equipment should know the
meaning of the rules and laws in terms of handling the equipment. Use
the hammer in accordance with all regulations regarding construction
practice and public safety.
For emergency use, keep the fire extinguisher and the first-aid case in
the operator’s cab.
Figure 4
1.2. Pre aration for safe o eration
Some prior checks and scheduled maintenance must be performed on installing a new hydraulic hammer.
The hydraulic hammer should only be mounted on a carrier with sufficient load capacity.
In case of using a quick coupler (hitch), determine the total weight including the quick coupler.
Carriers below this weight class will not provide the required degree of stability and could even fall over
during hammer use, causing personnel injury or machine damage. Carriers above this weight class may
apply excessively high mechanical loads to the hammer.
Make sure the hammer is compatible and match in capacity with carrier hydraulic systems.
To protect the operator from injury due to flying rock splinters, the operator’s cab should be equipped
with a protective shield or splinter guard. For information on the cab protector, consult carrier
manufacturer or PRODEM dealer.
Mounting the hydraulic hammer requires the presence of an assistant, who must be instructed by the
carrier driver. The carrier driver and assistant should agree beforehand on clear hand signals.
To avoid equipment damage, follow the carrier maintenance schedule before operating the hammer.
Check the hammer for wear, getting loose, breakage or crack. Do not operate in case any damages or
failure is found.

1.3. Safety information on safe o erating
Always operate the hammer from the operator’s seat in the carrier cab, and also close the splinter guard
on the driver’s cab during hammer operations.
The hydraulic hammer must not be used for disallowed applications. Refer to Section “6.2. Correct
working methods” of this manual for instructions on how to handle the hydraulic hammer, and
applications for which the hydraulic hammer is unsuitable and must not be used.
Stop the operation if an abnormal noise or vibration is detected during the operation. Check the carrier
and hammer.
Never use the hammer in or underwater unless compressed air is supplied to the hammer. Refer to
Section “6.2. Correct working methods for details”.
1.4. Safety information on maintenance
Always follow the instructions described in this manual when performing maintenance work on the hammer.
Pay careful attention to all relevant safety regulations. Most accidents occur when the instructions are
not observed.
Maintenance work should be performed with the carrier completely stopped, the stop valves shut off.
The carrier must be on firm and flat ground with all the control levers switched off.
Use only the lifting points provided and sufficiently strong lifting equipment when lifting the hammer.
Do not start maintenance on the hammer until it has cooled because the hammer is heated up during
operation. Some components, for example, chisel (tool), valve, piston or hydraulic connection parts
become very hot.
The hydraulic oil may be very hot and may cause severe scald. Before disconnecting hydraulic lines,
bleed all hydraulic pressure in the lines. And, always relieve tank pressure of the carrier.
Oil spouted out from the crack or small hole on hydraulic system can penetrate the skin and cause
serious injury. Therefore, be sure that all the connections are tight and pipes and hoses are in good
condition. Use a sheet of cardboard or wood to search for suspected oil leaks.
To avoid an explosion and equipment damage, use only pure nitrogen gas (99.8% or over) in the gas
chamber of the back-head and accumulator.
Only the proper tools should be used for maintenance. Use of improper tools may cause personal injury,
or damage to the hammer.
Oily, greasy ground may be very slippery. Collect any oil and grease, and dispose it correctly for safety
and environment.
Keep personnel away from the hammer while servicing the chisel, gas chambers or hydraulic system.
Unauthorized alteration on the hammer may cause the hammer serious troubles or reduce hammer life
and performance. These cases cannot be guaranteed by PRODEM.

5. Installation
IMPORTANT!
Improper installation can cause serious damage to the hammer and to the carrier. Do not install
the hammer if you are unsure. Contact your PRODEM dealer for more information.
5.1. Carrier requirements
The PRODEM hammer can be installed on any carrier that meets necessary mechanical and hydraulic
installation requirements. Refer to Section “4. Technical specifications” to determine the carrier specification
required.
Check following points when installing the hammer:
Carrier weight:
The hydraulic hammer should only be mounted on a carrier with sufficient load capacity. In case of using
a quick coupler (hitch), determine the total weight including the quick coupler.
Mounting dimension:
To fit the hammer on the carrier, proper mounting adapter must be used. This mounting adapter varies
according to carrier model and should be ordered separately with follows:
Excavator model and year built
Arm(stick) type
PRODEM’s standard mounting adapters are designed to fit most carrier, and parts for fitting, such as
spacers and pins can also be provided.
Hydraulic line:
Check the nominal bore size of the hammer piping lines on the carrier. Both supply and return lines must
have sufficiently large inner diameters. Small line size causes backpressure increase, overheating of oil
or irregular blows.
Hydraulic pressure:
The hydraulic pressure and oil flow of the carrier’s hammer piping should be adequate for operating the
hammer.
The maximum hydraulic pressure of the carrier must be higher than the recommended relief pressure
setting for the hammer. If not, the impact rate of the hammer becomes slow or the hammer does not start
blowing.
Oil flow:
Oil flow, which controls impact rate of hammer, is the most important factor in the hydraulic parameters to
operate hammer with a good performance, and should not only be too low but also be too high.
Insufficient oil flow cause low impact rates, and on the contrary excessive oil flow causes an increase in
the operating pressure and overheating of the oil. If the output of the pump is more than the maximum
acceptable flow of the hammer, a flow control valve is needed.
Oil cooler:
Too low or too high oil temperature reduces the working performance of a hammer. The temperature of
the hydraulic oil shall never exceed 90°C (194°F), maximum allowed limit, which may cause damage to
the hammer as well as the carrier. If the carrier’s oil cooler is too small, either the original cooler should be
replaced with a larger one or an auxiliary cooler must be installed.
For sufficient cooling of oil, return oil from the hammer must run through oil cooler to oil tank.

5.2. Attaching the mounting ada ter
1. Stand the hammer on the flat and stable base or lay the hydraulic hammer on squared beams or a pallet
with the service window of the hammer box facing upwards.
2. Fix the adapter (1) to the hammer box with two screws.
For silenced hammer, insert the upper damper (2) in the hammer box before fixing the adapter.
3. Then fit all screws (3) and tighten to the specified torque. The sizes of screws for different hammer types
are as follows;
PRB008 ~ 030
PRB040 ~ 150
PRB170 ~ 300
PRB400 ~ 700
: 12 mm
: 20 mm
: 30 mm
: 36 mm

5.3. Mounting the hydraulic hammer on the carrier
DANGER!
While mounting the hammer or removing the bucket, make sure that there are no persons in
the vicinity of the carrier.
When moving the carrier, do not touch any part of the carrier or hydraulic hammer. Keep
hands away from linkage area and pin-bores.
When aligning pin-bores, never put a finger into the bore, align only by sight or with using drift
pin.
Agree with the assistant on clear hand signals.

During hammer mounting, the carrier should only be operated from the operator’s cab.
1. Following the direction of an assistant, carefully move the excavator arm (2) into the adapter (4), until the
bore in the arm is flush with those in the adapter.
2. Insert the arm pin (3).
3. Fit the stop ring (5) to the arm pin (3) and lock by using the bolt and nuts (6).
