death.
Use the proper tools for inspection or maintenance work, which
must be carried out after ensuring the equipment stops completely
and is placed stably in the safe place
Figure 1
Know your equipments
Never fail to read and understand the safety messages, operation
manual and maintenance manual before installation and operation
of the compactor. The operator who has been trained and licensed
should only operate the carrier and the compactor. Familiarize
yourself with the operating especially safety related devices such
as safety lock, emergency stop and the others.
Figure 2
Know the work site
Before beginning operation, check in and around the work site for
any unusual conditions that could be dangerous and prepare the
appropriate warnings for safe work.
Be careful, especially when work in the vicinity of electric power
line, buried gas lines or oil tank. And pay your careful attention to
the people and the cars reside and passing near to the work site.
Prepare for every possible injury and damages.
Figure 3

1.2. Preparations for safe operation
WARNING!
The following section describes the matters that must be prepared and checked in advance
for safe use of the compactor. Make yourself familiar with and keep the following instructions.
Install to a suitable arrier.
The excavator to which compactor is to be mounted should be selected based on the compactor capacity,
the mounting dimensions and the hydraulic device specification. If equipment that does not comply with the
prescribed specification is used for the compactor, either the compactor or the equipment may be damaged
or its life may be shortened. So, be sure to mount the compactor to the specified excavator. For matters
concerning the equipment selection, contact us or our sales representative.
Safety Guidelines for Installation
Install the compactor to the arm and link of the excavator, using mounting pins. The excavator operator and
the mounting worker should pay special attention, and agree on details and sequence of the work and
determine hand signals in advance. The operator should run the excavator as slowly as possible and the
worker should keep a safe distance and should keep his hands off from the excavator arm or link while the
excavator works. After assembling the mounting pin, tighten the bolts firmly, so that the pin may not get loose
during work.
When installing a pipe for mounting the compactor, follow our pipe installation specification. When
connecting a hydraulic hose, connect it with the specified connection torque and check if the hose is
completely connected before starting the excavator. If a sudden pressure is applied when the connection is
incomplete, the hose may sway to cause personal injury.
For more information about piping and pipe installation, see “3. Installation” in this Manual.
Inspe t the equipment before work.
Carefully inspect each checkpoint of the compactor and the
excavator before starting work. Check everything related to
safety such as equipment damage (breakage, crack, wear and
tear, deformation, etc.), part connection state and oil leakage
according to the check items specified in the operation manual
and that of the excavator. In particular, focus on checking if
there is any crack in the welded parts on the compactor body,
if bolts/nuts in each joint are loose, pin fixing state and
leakage from cylinder and hose.
If there is any problem in the compactor or in the excavator,
do not operate the excavator until proper maintenance work is
done. In this case, attach a warning tag to the equipment
driver seat so as to inform other people clearly of the
equipment status. It is desirable that the same person who
attached the warning tag removes it in person.

1.3. Safety information for operation
WARNING!
The following is the safety guidelines especially focused on using the compactor. Follow
these guidelines and refer to “4. Operation” for detailed information.
Never operate in unallowed appli ations
Do not carry out dangerous works that are not allowed in this manual. Improper operation of the compactor
could result in serious injury or death. For a correct method for using the compactor, see “4.2 Correct
Working Methods”.
Do NOT use for on rete or bedro k
Operating the compactor on the hard object such like concrete or bedrock will cause damage to the
compactor. Use the compactor only for soft objects.
Do NOT use for breaking or transport
Hammering or ramming with the compactor body to break a object or transporting a heavy object using the
compactor may damage the product and shorten its life, so it is absolutely prohibited.
Do NOT use under water
Never use the compactor in or under water. Operating the compactor under water will cause serious damage
to the cushion rubber.
Do NOT support arrier with ompa tor
Do not support the carrier using the compactor body, or do not apply excessive force to it.
For piling work, always use pile- lamp
When operating in piling work - driving-in or pull-up, always use the optional pile-clamp for safety. Piling
without the pile-clamp can bring out the risk of falling down of piles.
Do NOT use for rane work
This product is not equipped with safety devices for crane work. So, never perform crane work with this
product.
Stop working if any problem is found
If the compactor shakes unusually or there is abnormal vibration and/or noise during work, stop operating
immediately. In addition, if oil leakage from hose connections or any loose pin or joint is detected during the
operation, stop the compactor and check the problem.

1.4. Safety instru tions for maintenan e
Follow the manual
Follow the instructions in the manual for inspection and maintenance. In
particular, pay special attention to safety alerts and do not rush. Accidents
during maintenance are mostly attributed to negligence of the guidelines.
Figure 6
Completely stop the arrier
Inspection and maintenance should be done, after completely stopping the excavator on an even and safe
surface, with all control levers and switches on safe position.
Use proper tools
Use proper tools for inspection and maintenance. If you carry out any inspection or maintenance work using
improper tools, it may result in personal injury or damage to product.
Pay attention to hydrauli system
Draw special attention to maintain hydraulic system. Even though it is stopped,
the inside of a hydraulic system that has been operated can be hot. So, do not
disassemble it rashly. Be sure to remove the pressure left inside the hydraulic
device, close the lock and prevent any external forces from being applied to the
device according to a maintenance guide, before maintain it. For the compactor
cylinder in particular, there may be pressure left in the system even after the
compactor stops, and it may be exploded when it is disassembled. Therefore, be
sure to follow the disassembly order.
If there is a tiny hole or crack in the hydraulic device, pressurized fluid may
spout from it, to injure people near it. Fluid that spouts lightly may not be seen
by the naked eye. In this case, check the leakage using a sheet of paper or a
wooden board, wearing eye protection.
Right after operation, fluid is very hot. So, you have to be careful not to get
burned. In addition, as air inside the oil tank of the excavator is compressed, a
large amount of hydraulic oil may gush out if the hydraulic line connected to the
oil tank is disassembled. So, open the filler-cap slowly to remove the
compressed air from the oil tank before disassemble the hydraulic device.
Figure 7
Remove oil from the floor
When there is oil on the floor, it may result in an accident. So, when you spill or drop oil on the floor, wipe it
out immediately .
Do not alter or modify
Unauthorized product modification or attachment of any unauthorized accessories can cause very dangerous
accidents. In addition, use of non-genuine parts can result in accidents or product damages. Therefore, use
our genuine parts only.

Functions of the major parts are as follows
Upper frame and base frame are the structures that form upper and lower parts of the Compactor
body.
In Drive casing, drive axis with eccentric weight which generates compacting force and bearings
that support the axis are assembled.
Motor (hydraulic motor) rotates at high speed by pressurized hydraulic oil from the carrier, to drive
the eccentric axis, and the vibration and centrifugal force induced by the rotation of the eccentric
weight generates compacting force.
Motor control valve is a built-in integrated valve to protect the hydraulic motor. There are two type
of the motor control valve; ‘N’ type valve has the reverse-flow-bypass and anti-cavitation functions
and ‘P’ type valve includes flow and pressure control function in addition to the standard features of
the ‘N” type valve.
Compacting plate contacting the ground compacts soil and make surface flat.
Cushion rubbers (cushion plates) is parts that help get effective compacting force from the
centrifugal force generated from eccentric weight and protect the carrier and operator by dampening
the vibration during compaction work.
Mounting plate is used to mount the compactor to the carrier using a mounting adapter.
’P’ port (IN) and ’T’ port (OUT) are connection ports to connect with piping of the carrier.

2.2. Produ t features
High compacting productivity
PRODEM’s hydraulic plate compactor guarantees high compacting productivity by means of powerful impulse force.
Easy and versatile mounting
Adapter Mount: Flat top frame allows for installation on any carriers using a standard or custom made mounting
adapter.
Direct Mount: The frame is designed to accept a variety of slip-fit bushings and pins, resulting in versatile
installation on any carrier.
Firm and safe hose array
All Hoses are routed within the frame and connected to a mono hose block located on the frame. It protects the hoses
from damage and make it easy to connect the hoses.
High quality cushion rubber
Specially designed high quality cushion rubbers dampens vibration effectively and thus protect carrier and operator
from the vibrations.
Heavy duty gear motor and bearings
Heavy duty and high efficiency gear motor with splined shaft and self-aligning double row spherical roller bearings
provides a long service life of the rotating components and prevent possible damage caused by pressure shock
during start-up and shut-down.
 Easy maintenance
Every part of the compactor is very easy to access for the maintenance.
Motor with built-in cross-check valve
Built-in cross-check valve within the hydraulic motor eliminates the need of a additional drain line, thus provides great
versatility for using general 2-line plumbing. And it also protects the motor shaft seal from damage caused by internal
oil leak of the motor.
Standard motor control valve (Reverse-flow-bypass and anti-cavitation check)
Built-in high flow check valve within standard motor control valve (‘N’ type valve) protects the motor from damage
caused by unintentional reverse connection of plumbing and cavitation induced by abrupt shutdown of hydraulic flow.
 Optional motor control valve (Flow & pressure control)
Flow control valve (Pressure compensated priority flow divider) regulates hydraulic in-flow to the motor not to
excess the permissible maximum flow of the motor to prevent it from over-speeding. Thus, the compactor can be
installed on a carrier not equipped with a flow control valve on its auxiliary plumbing. And, it also control the motor
speed regardless of load pressure to generate the maximum compacting force continuously.
Pressure relief valve is also incorporated in the optional valve pack and it prevents system from over-pressure to
protect the motor. An attachment, such as breaker, which works at a relatively higher pressure than compactor can be
easily switched to the compactor on the same auxiliary plumbing without re-setting of the carrier’s relief valve
pressure.
All the valves; flow control, pressure relief, and reverse-flow-bypass & anti-cavitation check valves are packed within
the single mono valve block (‘P’ type valve).

Figure 12 The above circuit diagram is for reference only.
The specifications of carrier’s hydraulic system required to operate the compactor is as follows.
Pump Flow: Higher than the minimum working flow of the compactor
System Pressure: 180 bar or higher
Allowable Back-Pressure: 15 bar or less
Compactor piping is basically the same as breaker piping, and thus it is possible to use the breaker piping
as it is without any modification.
★But, the drain(low-pressure) line must be connected directly to oil cooler or oil tank.
If the drain line is connected to the control valve of the carrier, the compactor’s motor can be
damaged.
If the drain line of carrier has a stop valve for by-directional operation, be sure to operate the compactor
with opening the stop valve.
The drain line should has sufficiently large inner diameter to meet the specified maximum acceptable
back-pressure of the compactor. If the back pressure – measured at the ‘T’ port during operation – is
higher than the specified value, check the inner diameters of pipes, hoses or fittings of the drain line.

Setting and Adjusting Relief Valve (※
※※
※)
For the compactor with ’N’ type valve, a relief valve must be installed to compactor piping, and must be
adjusted to the specified maximum operating pressure ot the compactor.
For the compactor with ‘P’ type valve, you do not need to install a relief valve to compactor piping. If a
relief valve has already been installed for other attachment, such as breaker, you do not also need to re-
adjust the setting pressure according to the compactor’s operating pressure.
Please consult PRODEM or our dealer for more detail about the compactor piping.
Piping should be placed as follows when the compactor is viewed from the operator in carrier’s cab:
P Line (IN) : Left
T Line (OUT) : Right
When ‘P’ and ‘T’ lines are reversed with each other, the compactor does not work or rotate very slowly by
means of the reverse-flow-bypass check valve of the motor control valve to protect the hydraulic motor.
So, make it sure that piping is installed in right direction.
When you newly install piping, make it sure that there is no foreign substance inside piping sub-parts
such as hoses, pipes, valves and fittings. After finishing installation of piping, connect ‘P’ and ‘T’ line
directly to each other without connecting the compactor and do flushing process during minimum 5
minute to make hydraulic oil clean before connecting the hoses to the compactor.
Be sure to use piping parts that conform to the hydraulic specification of the compactor and carrier. When
using the compactor with the piping modified for other purpose or modified with parts whose configuration
has not been confirmed, be sure to consult our service or dealer. Remember that problems resulting from
wrong piping or wrong installation are not covered by our warranty.

3.2. Installation of the ompa tor
Mount the compactor to the carrier as following;
1. In case of adapter mounting type (‘NA’ or ‘PA’
version), assemble a mounting adapter to the
compactor as shown in Figure13.
2. Place the carrier and compactor on flat and firm
ground in the direction as shown in Figure 13.
3. Assemble the spacers and shims to the bores
of the mounting adapter.
The dimensions of the spacers and the number
of shims may vary depending on carrier’s
mounting dimensions, such as the pin diameter
or the width of the arm or link.
4. Move carrier’s arm slowly until its pin-bore is
flush with the pin bore of the mounting adapter,
and insert the mounting pins.
5. Assemble the stop-rings, and tighten bolts and
nuts to fix the mounting pins.
6. Then, assemble the mounting pin for carrier’s
link in the same way as for carrier’s arm.

DANGER!
When moving the carrier, do not touch any part of the carrier. Keep hands away from linkage
area and pin-bores of the carrier.
When aligning pin-bores, never put a finger into the pin-bore, align only by sight or with using
drift pin.
Agree with the assistant on clear hand signals. The operator in the carrier’s cab should run the
carrier as slowly as possible. When the carrier is moving, workers should keep safe distance
from the carrier.

- 16 -
Connect the hoses to the carrier as follows;
1. After assembling of the mounting pins is completed, turn off the excavator completely.
2. Close the stop valves on the arm end, and remove caps.
3. Connect hydraulic hoses as shown in Figure 14. Make it sure that ‘P’ and ‘T’ lines are not reversed each
other.
4. When connecting the hoses, make it sure that no foreign substances get into the hoses. Dirt, sand or it
may cause a serious trouble to the compactor and carrier.
5. Arrange the connecting hoses not to be twisted or excessively bent.

When all installation works are completed, check the followings before operating the compactor.
While moving the carrier’s bucket cylinder slowly in and out – in the direction of ‘crowd’ and ‘dump’,
check;
Any interference or obstruction between the compactor and carrier,
Whether the length of the connecting hoses are too short or too long,
Twisting, excessive bending or squeezing of the connecting hoses,
Fixing status of the mounting pins.
While operating the compactor with lifting up the compactor not to touch the ground (no-loading condition),
check;
Whether the compactor runs normally without delay when the operating switch is pressed ON, and it
stops when OFF.
Any oil leak from hoses, fitting, hydraulic motor or motor control valve,
Loosening of bolts or nuts,
Crack or tear out of the cushion rubbers,
Abnormal vibration or noise while the compactor running.

4. Operation
DANGER!
The following section describes a correct use and precautions for compactor operation. These
are the fundamentals for safe operation. So, make yourself familiar with them before initial
use.
IMPORTANT!
If you operate compactor, having it touched a solid ground such as concrete floor or a
bedrock, it would apply very high impact to the compactor, which might result in a serious
damage to the compactor.
4.1. How to use ompa tor
Place the compactor on the ground you want to compact to be in touch with it uniformly.
Lower the carrier’s boom slowly to press the compactor vertically to the ground. At this time, make it
sure that cushion plate is pressed less than 4 cm. If the cushion plate is pressed more than the
specified limit, it might be damaged or its life might be shortened.
If you operate the compactor, having it touched a very hard object such as concrete floor or bedrock,
it would apply very high impact to the compactor, which might result in a serious damage to the
compactor.
When the ground starts to be lowered by compacting work, lower the carrier’s boom gradually and
keep a constant applying pressure. At this time also, make it sure that the cushion plate is not pressed
too much.
When compacting a wide area, advance working positions sequentially in a uniform direction with
some overlapped area.
Mostly for normal soil condition, proper working time is 5 ~ 10 seconds at once.
Continuous operating for a long time have no more effect on compacting and, on the contrary, may
result in trouble to the compactor.
To obtain optimal compaction of the soil, repeat the compacting work in two or three passes. The
duration of compacting for the later pass can be shorten than initial pass.
★Do not use for the following objects:
Concrete floor
Bedrock or surface covered with stones
Steel plate
Press down in a
direction vertical
to the ground.
Continous
operating time
should be
limited to 10
seconds or less.

4.2. Corre t working method
IMPORTANT!
Figure 16
Keep vertical to the ground.
Operating the compactor with a tilt
to the ground surface –without
uniform contact to the ground–,
the compactor might be damaged.
Always keep the compacting plate
in parallel to the ground and press
it vertically to the ground.
IMPORTANT!
Figure 17
Do not transport using the
compactor.
Do not move or break a heavy
object using the compactor, which
may result in the compactor
damage or shorten its life.
IMPORTANT!
Figure 18
Do not support carrier with the
compactor.
Do not support the carrier using
the compactor body, and do not
apply excessive force to the
compactor.

- 19 -
IMPORTANT!
Figure 19
Do not use for unallowed
purpose
If the compactor is used for
unallowed purpose or harsh work
which apply exce
ssive force to the
compactor, both the compactor and
the carrier would be damaged and
their lives rapidly shortened.
DANGER!
Figure 20
Do not use for crane work.
The compactor is not equipped
with safety devices for crane work,
so it is very dangerous to use the
compactor for crane work. And
also, lifting a heavy object up with
the compactor will result in severe
damage and shortening of its life.
IMPORTANT!
Figure 21
Do not work under water.
The compactor should not be used
for underwater work. Operating the
compactor under water will cause
serious damage to the cushion
rubbers.
