obtained working a laminated aluminium block
1. OIL INLET HOLE – oil enters in pressure in the valve from this hole
2. ROTATING JOINT is an adjustable joint where the quick couplers are installed. It permits to fold the
quick coupler after the use protecting it against shocks. It also allows the flexible hose to have a
natural bend avoiding sharp bends.
3. FILTER CARTRIDGE is the hydraulic oil filter. It can easily substituted but it cannot be maintained
4. MALE QUICK COUPLER is the quick coupler which the oil comes out under pressure through from
“P” power pack. The male quick coupler should always be installed in this position for guaranteeing the
right circulation of the oil.
5. ON/OFF FLOW LEVER is the lever which the oil is sent to flexible hoses and hydraulic tool through. It
is OFF placed rightwards, it is ON placed leftwards.
The lever should always be in OFF position at the end of operations or when the engine is started and
when the Manta power pack is used as a generator. The illustration shows the lever as installed on
the model SCORPION ( pointed to the center of the pack ), on the RAPTOR D the lever is installed
on the front part ( pointed to the exterior ) but the sense of the ON OFF position is the same , the
RAPTOR D imagine of the flow is on the illustration at page 11
6. OIL OUT LET HOLE On the model RAPTOR D this hole is plugged as the oil baypasses to tank from
an internal passage.
7. PRESSURE RELIEF VALVE is the valve adjusting the maximum value of the hydraulic pressure of the
power pack. It is adjusted originally at a value of 140 BAR. It can be adjusted at different values of
pressure
8. ROTATING JOINT is an adjustable joint where the quick couplers are installed. It permits to fold the
quick coupler after the use protecting it against shocks. It also allows the flexible hose to have a
natural bend avoiding sharp bends..
9. FEMALE QUICK COUPLER is the quick coupler which the oil returns to tank “T” The female couplers
is in communication with tank and should always be installed in this position for guaranteeing the right
circulation of the oil.

FLEXIBLE HOSES
THE POWER PACK ARE USUALLY EQUIPPED WITH A COUPLE OF HYDRAULIC FLEXIBLE
HOSES OF 7 M. OF LENGTH COMPLETE WITH FLUSH-FACE QUICK COUPLERS
-The following general information can be useful in case of new hose supply o when it is
necessary to use hoses with different extensions than the standard ones.
THE FLEXIBLE HOSE consists of a couple of parallel hoses (a PRESSURE hose and a
RETURN hose) that connect the hydraulic tool to the power source..
When it is possible, do not use long hoses. The flexible hose should be long enough to permit a
good manoeuvrability of the tool but not too long, as a very long hose can be heavy, difficult to
transport and to handle and may also cause loss of power.
A flexible hose of ten meters is adequate in most of the cases to guarantee a good
manoeuvrability. If a longer hose is necessary, just connect a second extension hose to the first
one .
•THE FLEXIBLE HOSE ALWAYS REMAINS FULL OF OIL. THE FIRST TIME A NEW HOSE
IS USED, IT WILL GET FULL OF OIL TAKING IT AWAY FROM THE HYDRAULIC CIRCUIT.
IT WILL BE THEN NECESSARY TO RESTORE ADEQUATELY THE OIL LEVEL IN THE
TANK.
• THE FLEXIBLE HOSES ARE ALWAYS IN CONTACT WITH THE GROUND AND
ARE SUBJECT TO STRONG VIBRATIONS AND ABRASION, THUS THEY
SHOULD BE RESISTANT TO WEAR AND ABRASION .

QUICK COUPLERS
The DOA power packs and hydraulic tools are equipped with flush-face quick couplers as those
one shown in the picture.
The following paragraph supplies information about the couplers and their use.
The standard quick couplers for hydraulic tools recommended by the ETHMA association are:
FLUSH-FACE QUICK COUPLERS
A COMPLETE QUICK COUPLER consists of a male and female element. (see picture)
The flush-face quick couplers are STANDARDIZED, and they can be found at the major
manufacturers.
The flush face quick couplers grant the best values of oil slipping, generate minimum pressure
drops, are easy to clean, do not drip during the operation of even accidental connection /
disconnection, and above all they are perfectly sealed out the dirt. This is a very important
characteristic for preventing oil contamination and damages to the tools.
\FLOW DIRECTION AND INSTALLATION OF THE QUICK
COUPLERS
The ideal flow direction is from MALE →FEMALE.
An arrow is punched on the couplers showing the right direction.
The couplers must be installed on the flexible hose, power packs and tools, respecting the
sequence previously described. The following illustration shows the right installation of the
couplers on the hoses. If the couplers are properly installed, wrong or inverted connection will be
impossible and it won’t be necessary to pay attention making a connection. Every coupler will be
connected in the right way.

13
USE OF THE QUICK COUPLERS
CONNECTION
•Make sure that the contact surfaces of the couplers are clean and if necessary wipe the dirt
with a rag.
•Position the male coupler towards the female one, centring them.
•Press the male coupler against the female one.
•A “click” indicates that the proper connection is made.
IF A PROPER CONNECTION CANNOT BE MADE EVEN PRESSING THE COUPLERS WITH
STRENGTH, IT IS POSSIBLE THAT ONE OR BOTH COUPLERS ARE PRESSURIZED .
FOR MAKING THE CONNECTION IT WILL BE THEN NECESSARY TO TAKE AWAY
PRESSURE BY UNSCREWING THE COUPLERS FROM THEIR FITTINGS AND ALLOW
SOME OIL DROPS TO COME OUT.
IT IS ALWAYS A GOOD PRACTICE FOR AVOIDING PRESSURE TRAPPING BEHIND THE
COUPLERS, FIRST TO CONNECT THE RETURN HOSE AND DISCONNECT IT LAST
DISCONNECTION
•Position the knurled bushing of the female coupler so that its slot is in front of the steel ball.
•Push the bushing against the steel ball.
•The male coupler will be released and a “click” will show the disconnection.
OTHER ADVICE
•The connection/disconnection of the couplers must be done always WITHOUT OIL
CIRCULATION – WITHOUT PRESSURE.
•Disconnect and connect the tools from hoses and power source, just after having set the
level of the flow switch valve in OFF POSITION.
•The quick couplers must be dismounted from the power pack only with the engine OFF.
•If you mount or dismount the quick couplers, use only the right wrenches. If improper tools
are used the coupler hexagon can be easily spoiled.
•The quick couplers CANNOT BE REPAIRED. Discard immediately damaged or deformed
couplers and not force the connection if one coupler is damaged. In this case the damaged
coupler will immediately damage also the other good interface.

SAFETY RULES
GENERAL SAFETY INSTRUCTIONS
THE FOLLOWING INSTRUCTIONS ARE GENERAL SAFETY RULES AND HAVE TO
BE RESPECTED IN EVERY WORKS WITH POWER PACKS AND HAND TOOLS. WE
RECOMMEND TO FOLLOW THEM CAREFULLY IN ORDER TO AVOID ACCIDENTS
AND DAMAGES TO THE EQUIPMENT AND THINGS .
•Wear ALWAYS the hard-helmet, safety goggles, gloves, safety shoes, ear protections and,
when it is prescribed, a dust musk.
•Wear tight-fitting clothes and avoid operating with short trousers or t-shirts, or other bare
parts of the body. Pay attention to long loose hair, gather them to prevent they get in contact
and trapped in moving parts.
•Before operating, PREPARE ALWAYS A WORKING PLAN that considers and foresees
problems, interruptions and avoids most of all dangerous situations. This little operation
strategy, guarantees safety and improves productivity
•Place always the power pack in a plan level, in a sure and stable position protected from the
traffic and in a well visible position. Signal one’s position not to cause danger for oneself and
others.
•If the power pack is transported on vehicles, be sure that it is well positioned on board and it
is blocked on the loading platform for avoiding dangerous jerks, bumps or overturning.
•Work only in good physical and mental conditions. Always pay the maximum attention!
•Do not work on unstable or adapted supports (such as oil cans, boxes, wheelbarrows, etc.).
If you need to work in elevated positions, use only stable and safe supports approved by the
local safety rules.
•When you operate in difficult positions, do not reach out and never lean against the tool.
Keep the balance on your legs.
•Be sure that the equipment is in perfect working conditions, without oil leaks.
•Keep the protection devices always in good conditions and preserve the readability of the
safety stickers.
•The working area must be examined and well-known to avoid unexpected situations. If you
work along roads, make well visible your position and warn the traffic by the use of signals,
flashing lights, or other prescribed road signs.

15
•WORK ONLY IF THE ENGINES ARE OUTSIDE OR IN A WELL VENTILATED POINT.
THE EXHAUST GAS OF THE ENGINES IS ODOURLESS AND ITS INHALATION CAN
CAUSE SERIOUS OR FATAL ACCIDENTS.
THE CONTACT WITH ELECTRIC ENERGIZED LINES CAN BE FATAL
• Pay the maximum attention when you cut, demolish, drill, etc. near energized electric lines
that can be buried, walled or hidden.
• Be very careful also to gas and water pipes, telephone lines or other buried cables or ducts.
•The working area must be free from objects that may fall, get spoiled, catch fire, make trip up
or make the operation difficult or dangerous.
•Warn and move away imprudent bystanders or other people not authorized or involved with
the job.
•If you work in narrow or closed rooms always plan a way out that must be kept free.
•Make sure that the operation point is the right one and that there are the proper
authorizations of the owners before starting the works.
•Before working always foresee where the demolition fragments, water pumped, sparks or
splinters are going to stop and plan the opportune defences and counter measures.
•Before using the equipment make sure and prevent vehicles, machines or people from
passing on the equipment hoses or cables.
•Always connect tools to the power pack or other power sources before starting the engine.
•Keep in a safe dry place this manual and its enclosures, so they can be always available for
future consultations.

REPAIRS NOT WELL DONE OR USING INAPPROPRIATE PARTS CAN CAUSE
DANGEROUS SITUATIONS
•DO NOT CARRY OUT CONTROLS ON THE POWER PACK CHECKING OR TOUCHING
WITH BARE HANDS AND ENGINE ON. ALWAYS STOP THE ENGINE AND COOL DOWN
THE EQUIPMENT BEFORE CHECKING AND CLEANING IT
•DO NOT PULL THE FLEXIBLE HOSES OF THE POWER PACK. IF THE MACHINE
SHOULD BE REPOSITIONED USE THE PROPER HANDLES.
•DO NOT TRY TO LIFT THE POWER PACK ALONE FOR LOADING OR UNLOADING IT
FROM VEHICLES. THIS CAN CAUSE DANGERS AND ACCIDENTS
BEFORE WORKING
THE FOLLOWING INSTRUCTIONS AND CHECKS SHOULD BE CARRIED OUT
EVERY TIME THE POWER PACK IS USED AFTER A PERIOD OF INACTIVITY OF
THE MACHINE OR WHEN IT IS USED BY OTHER PEOPLE
1. CHECK THE LEVEL OF THE ENGINE OIL with cold engine and with the machine in
horizontal position visualize its level on the level indicator and fill if necessary
2. CHECK THE FUEL LEVEL be sure that the tank contains enough fuel for finishing the work,
fill it if necessary using an appropriate fuel, DO NOT FILL WITH STARTED ENGINE !
3. CHECK THE LEVEL OF THE HYDRAULIC OIL, fill with the same and compatible hydraulic
oil than that one of the tank – do not exceed the suggested level, the level should be visible
from the level indicating eye. In case of very cold temperatures, follow carefully the
instructions “ starting at low temperatures “ below described
4. CHECK THAT THE TOOL USED AND THE POWER PACK HAVE COMPATIBLE
HYDRAULIC CHARACTERISTICS – IN CASE OF DOUBT DO NOT RISK but ask your DOA
dealer or your foreman.
5. CLEAN THE POWER PACK PROPERLY if it is dirty, in particular clean the cooler eliminating
mud or dirt, use compressed air if necessary ( see chapter ” cleaning and maintenance of the
equipment “ ). Check and clean also the suction mouth of the cooler cooling air.
6. CHECK THAT ALL THE EQUIPMENT IS COMPLETE AND EFFICIENT, that there are not oil
leaks and screws, joints and plugs are well tightened.

18
START AND USE OF THE POWER PACK
COLD START
THE POWER PACK SHOULD BE PROTECTED FROM BAD WEATHER AND TOO HARD CLIMATES.
THE BATTERY AND ENGINE COULD BE QUICKLY DAMAGED IF THE MACHINE IS LEFT EXPOSED
TO RAIN AND LOW TEMPERATURES WITHOUT PROTECTION. WHEN THE MACHINE IS NOT USED,
IT SHOULD BE STORED IN A DRY AND WARM PLACE REPAIRED FROM RAIN AND DAMPNESS.
THE POWER PACK IS EQUIPPED WITH A HYDRAULIC OIL COOLER PLACED ON THE SUCTION
LINE. THIS COOLER POSITIONING BETWEEN THE OIL TANK AND GEAR PUMP ASSURES THAT
THE COOLER IS NOT PRESSURIZED AND KEEPS IT PROTECTED FROM HARMFUL PULSATION,
IMPROVING THE RELIABILITY OF THE MACHINE.
IF YOU WORK IN BAD WEATHER, WHEN THE OIL CAN BE VERY HARD AND VISCOUS, IT IS VERY
IMPORTANT TO RESPECT THE FOLLOWING INSTRUCTIONS IN ORDER TO AVOID PROBLEMS OF
THE PUMP SUCKING THE OIL ( CAVITATION PHENOMENON )
1. USE HYDRAULIC OIL WITH THE RIGHT VISCOSITY ( SEE THE TABLE OF THE HYDRAULIC
OILS IN THE PREVIOUS PAGES )
2. AFTER HAVING CONNECTED THE FLEXIBLE HOSES AND THE TOOL TO THE POWER PACK
( see following paragraph ), START THE ENGINE KEEPING IT AT THE MINIMUM FOR A FEW
MINUTES, THEN PUT THE FLOW LEVER IN “ON” POSITION, MAKING THE OIL CIRCULATING
INTO THE HOSES AND THE TOOL UNTIL THE OIL IS LUKEWARM TOUCHING THE TANK.
IT IS ADVISABLE FOLLOW THIS PROCEDURE IN ALL COLD STARTS
POSITIONING OF THE POWER-PACK
1. Using the transport handle, pull or push the power pack, bringing it to the working point. After
having reached the operating point, bend the grips for avoiding bumps or deformations.
2. The power pack should be placed in a flat place protected from the traffic, in well established,
firm, visible and well ventilated position.
Inflammable objects or materials should be kept away from the power pack, in particular from
the discharge side.
3. Hoses should be laid down tidily and linearly avoiding knots and tangles, also for preventing
possible stumbles.
Be sure that no vehicles or machines pass on the hoses spoiling them.
4. Do not work with the power pack left on lorries or on the platform of trucks. It is better to leave
the power pack on the ground. If the power pack should work on vehicles, be sure that it is far
from the lorry boards or sides, so that both the cooling air of the engine or cooler, and the
exhaust gases can circulate and are properly dissolved.

19
If the hydraulic oil, lubricant or fuel is spilt on the ground, for any reason, remove the spilt
liquids using sawdust or rags for avoiding accidents and contamination of the ground.
ENGINE STARTING
Before starting the engine, the flow lever should be brought in OFF position.
If the lever is left in ON position, the starting will be very hard, the engine does not start
and the battery runs down completely in a few moments.
The power pack engine is with battery and recoil starting. Do not leave battery inactive for long
periods, they cannot be used if they are left discharged even for quite short periods. When they
are stored for long periods, it is advisable to disconnect the positive pole. In these cases it is
better to check the charge.
1. If the starting is made by recoil ( rope starting ) bring the starting switch in ON working
position.
If the starting is carried out with battery, bring the starting key in the START position and use
the battery staring.
FURTHER INFORMATION ON THE COMBUSTION ENGINE STARTING, ARE SUPPLIED IN
THE MANUALS OF THE ENGINE GIVEN WITH THIS MANUAL.
CONNECTION OF THE FLEXIBLE HOSES AND HYDRAULIC
TOOL TO THE POWER PACK
1. Lay down the flexible hoses avoiding the contact of the couplers with the mud or dirt, if
possible.
2. Put the tool on the ground limiting the contact with the mud or dirt. Make sure that the
tool is in perfect condition and its accessories are efficient and well installed. Make
sure that the tool trigger is free and released; control that the return spring of the
trigger is operative and efficient for avoiding an accidental starting.
3. First connect the flexible hoses to the power pack whose engine and flow control lever
must be OFF. Connect the female coupler of the hose to the male coupler of the
power pack, then make the other connection.
If correctly installed, the male coupler of the power pack is the one corresponding to the pressure
line, where the oil “gets out” from the power pack, the correct sequence of couplers installation
depends on the positioning of the first male coupler .the male coupler must always be installed
on the left of the valve block ( see illustration on page 15 )

20
If a flexible hose full of oil remains under the sun, the oil expansion due to the heat can
cause a pressure increase and prevent the connection of the quick couplers. To decrease
pressure, loosen one coupler, dripping some oil drops de-pressurizing the hose.
4. Now connect the flexible hose to the hydraulic hose of the hydraulic tool, connecting the
first the return hose corresponding to the hole with the message OUT of the tool bringing
the male coupler on the tool.
5. Thus the hydraulic connection is completed.
6. Start the power pack leaving it at minimum for a few minutes. Follow the instruction of the
paragraph “cold start” if the starting is occurring at cold.
RAPTOR D has manual acceleration , the engine must be accelerated manually
7. accelerate the engine by using the lever
8. The tool is now ready for starting.
9. Press the tool trigger and work
END OF THE OPERATIONS
1. Lay down the tool avoiding and limiting contacts with the mud and dirt, if possible
2. PUT THE ENGINE ACCELARATION AT IDLE , minimum speed of the engine .
3. Put the ON OFF flow lever of the power pack on the LEFT position in idle position, blocking
the oil supply to the tool.
4. Stop the engine bringing the starting key in OFF position.
5. Disconnect the tool from the flexible hose releasing first the PRESSURE HOSE
corresponding to the tool hole with IN. This operation will prevent accidental pressure
trapping inside the tool.
6. Disconnect the flexible hose from the power pack.
7. Roll up the flexible hose in circles of about 60 cm of diameter, connecting the quick couplers
at the extremities in the “head/tail” way. This operation will protect the couplers against
impacts or scraping and will also help in keeping the hoses well rolled up.
8. Remove the accessories from the tool and control that they have not been damaged during
the use. In case of breaks, discard them immediately or repair them for preventing their
accidental use in the future.
