TECHNICAL CHARACTERISTICS
GENERAL VIEW – MAIN COMPONENTS AND THEIR FUNCTIONS
Fig. 2 -HYDRAULIC POWER PACK MODEL - RAPTOR E
FOR THE FUNCTIONS OF THE ELECTRIC PANEL SEE ON PAGE 21
1. FOLDING HANDLE is a long handle allowing a comfortable manoeuvrability of the power
pack on the ground, both pulling and pushing. Its length assures that feet are not bumped
when the power pack is moved pulling it
2. ON/OFF FLOW LEVER when is in the ON position ( left side ) it allow to deliver flow to
tool, when is in the OFF position ( right side ) it makes the internal “by pass” .
The lever must be put in the OFF position when starting the power pack or when a tool is
connected to the pack or when the pack is put OFF.
3. FRONT PANEL on the panel there are the various stickers with working instructions, etc.
On some models on the panel there is the hour meter.
4. TANK – HYDRAULIC BLOCK is a unit manufactured in sheet steel containing the
hydraulic oil tank, air conveyor and all the accessory parts of the power-pack hydraulic
part.
5. HYDRAULIC OIL COOLER is an aluminium highly-efficient model controlling the oil
temperature. It is protected by a bumper grid
6. SIDE FOLDING HANDLES allow a comfortable gripping of the power pack and carries
out also the function of side bumper bar.
7. REAR FOLDING HANDLES give a comfortable gripping of the power pack in the rear
part.
8. ELECTRIC MOTOR

VIEW OF THE HYDRAULIC ON / OFF VALVE BLOCK
THE VALVE BLOCK is the seat af all components that controls the hydraulic circuit, the part is
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 motor is
started. The illustration shows the lever as installed on the model SCORPION ( pointed to
the center of the pack ), on the other power packs included the RAPTOR E the lever is
installed on the front part ( pointed to the exterior ) but the sense of the ON OFF position is
the same
6. OIL OUT LET HOLE ( only model SCORPION ) – the oil exits the valve at low pressure from
this hole and returns to tank.On the models RAPTOR – MANTA 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.

If you use the hydraulic tools in extreme climatic conditions, please contact DOA for more
information .
IN CERTAIN COUNTRIES OR IN SOME SPECIAL APPLICATIONS THE USE OF
BIODEGRADABLE OIL IS PRESCRIBED BY LAW, IN THIS EVENTUALITY CONTACT
DOA FOR MORE INFORMATION .
NORMALLY THERE ARE NO PROBLEMS OF HYDRAULIC-OIL COMPATIBILITY ( MIXING
DIFFERENT TYPES OF OILS ) WHEN A DOA TOOL IS CONNECTED TO THE CIRCUIT OF
AN EARTH MOVING MACHINE OR ANOTHER OPERATING MACHINE, IF THE OIL OF
THESE MACHINES IS OF A GOOD QUALITY AND REGULARLY FILTERED.

10
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
DOA POWER PACKS AND HYDRAULIC TOOLS ARE USUALLY 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.

14
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 ADVICES
•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.

17
USE OF THE POWER PACK
WHAT NOT TO DO
THE FOLLOWING LIST IS GIVEN FOR DESCRIBING THE MORE COMMON ERRORS OR
IMPROPER AND DANGEROUS USE OF THE POWER PACKS.
SINCE IT IS IMPOSSIBLE TO FORESEE ANY DANGEROUS SITUATIONS, THE RULES ARE
NOT SUFFICIENT TO GUARANTEE THE TOTAL SAFETY.
IT’S RECOMMENDED TO USE ALWAYS THE MAXIMUM CAUTION IN EVERY
CIRCUMSTANCES.
IN CASE OF DOUBT DO NOT RISK, BUT ASK YOUR FOREMAN.
WHAT NOT TO DO !
•DO NOT USE THE POWER PACK AND THE TOOL IF THERE COULD BE THE
POSSIBILITY OF GETTING IN CONTACT WITH ENERGIZED ELECTRIC LINES OR
PRESSURIZED PIPES.
•DO NOT START OR USE THE POWER PACK UNDER THE RAIN OR IN PRESENCE OF
VERY HIGH MOISTURE., BE CAREFUL ALSO IF THERE ARE STRANGE ODOURS,
THEY MAY BE DANGEROUS GASES OR EXHALATIONS ALWAYS PROVIDE THE RIGHT
VENTILATION.
•DO NOT START THE POWER PACK AND ITS TOOL IF THEY ARE DAMAGED, THERE

•DO NOT BELIEVE IN MESSAGES OR VOICE WARNINGS GIVEN TO COLLEAGUES IN
NOISY ROOMS. BE SURE THAT THE WARNING HAS BEEN CORRECTLY
UNDERSTOOD.
•DO NOT “POINT” THE TOOLS THAT ARE USED AGAINST COLLEAGUES
•DO NOT STAY WITH THE FACE TOO CLOSE TO THE TOOLS

18
•KEEP THE POWER PACK AWAY FROM INFLAMMABLE MATERIALS. DO NOT WORK IN
ENVIRONMENTS WITH VAPOURS AND GASES OR UNKNOWN ODOURS.
•DO NOT TRY TO REPAIR THE EQUIPMENT IF YOU ARE NOT A QUALIFIED PERSON.
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 ELECTRIC MOTOR 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 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
2. 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.
3. 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.
4. CHECK THAT ALL THE EQUIPMENT IS COMPLETE AND EFFICIENT, that there are not oil
leaks and screws, joints and plugs are well tightened.

19
POWER PACK START AND USE
COLD START
THE POWER PACK SHOULD BE PROTECTED FROM BAD WEATHER AND TOO HARD
CLIMATES. THE ELECTRIC PART OF POWER PACK CAN BE SPOILED IF THE MACHINE
IS LEFT EXPOSED TO RAIN AND VERY 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 MOTOR 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
POWER-PACK POSITIONING
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.
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.

20
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 COOLING AIR OF THE COOLER CAN
CIRCULATE WELL
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.
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 WITH ELECTRIC
MOTOR OFF ALSO 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 12 )
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. THE HYDRAULIC HOSE CONNECTION IS COMPLETED.
