EAGLE PRO INDUSTRIAL TOOLS, INC. 2 FORM NO. E09005 REV. A.  Use high quality impact sockets that are in good condition with the hydraulic torque wrench. Ensure they
are the correct size and engage the hex portion of the bolt/nut correctly. Unseen flaws or damage to the
impact sockets could cause failures during use. Remain clear of impact sockets during application.  Do not hammer on hydraulic torque wrench, pump or socket to enhance performance. If the bolt/nut will
not rotate, select a larger torque wrench for the application.  Do not pick up the torque wrench by the hydraulic hose or swivel.  Do not pick up the hydraulic pump by the power cord, pendant control cord, or hydraulic hose.  Electrical pumps should never be used in a potentially explosive environment.  Ensure that the pump is properly grounded to guard against electrical shock.  Do not use kinked or damaged hydraulic hoses.  Carefully inspect the hydraulic couplers on pump, hoses, and torque wrenches before using. Never
connect tools with damaged couplers or damaged port threads. The damaged coupler(s) or damaged port
threads may cause equipment failure and possible personal injury.
 Install couplers in a clean environment. Always prevent dirt or other debris from entering into the
cylinder. Dirt or debris will damage the tool and result in equipment failure and possible personal injury.
 Before removing or tightening hose(s) or coupler(s), always release hydraulic pressure in system .
 Never handle pressurized hoses; escaping oil under high pressure can penetrate the skin, causing serious
injury. Seek medical aid immediately if injured.
 When the pump is not in use, release the valve, remove the hoses and use the dust cap to recover the port.
 Do not drop anything on hydraulic hoses.
 Fully retract the hydraulic torque wrench before adding fluid to the torque wrench pump. Failure to do so
will result in excess reservoir pressure and could cause personal injury.
 Do not use equipment in temperatures of 150°F (65°C) or higher. Overheating will soften seals and
weakens hose materials, resulting in oil leaks or other equipment failure.
 For hydraulic technical help or repair service, please contact the closet authorized EAGLE PRO Service
Center. EAGLE PRO INDUSTRIAL TOOLS, INC. has no obligations under any warranty with respect
to products that have been repaired by unauthorized personnel, modified, or damaged through misuse,
abuse, accident, neglect, or mishandling.
DANGER!

valve. Before disassembling hydraulic torque wrench system for storage, transport or maintenance, always
release system pressure. Once work is completed, push the button on top of the
solenoid valve. See FIG C. Before disassembling hydraulic torque system, double
check pressure gauge located on pump to ensure system pressure has been released.
Once system pressure has been released, it is safe to disassemble hydraulic torque
system.
The pumps maximum working pressure is 10,000 PSI (700 bar) . Ensure that all
hydraulic equipment used with this tool are rated for 10,000 PSI (700 bar) working
pressure.
FIG C
WARNING!
Improperly connected hydraulic couplers can be dangerous if pressurized. Do not
grab, touch or come in contact with a pressurized hydraulic fluid leak. Escaping
fluid can penetrate the skin and cause severe injury.
03 OPERATION INSTRUCTIONS
3.1 ASSEMBLING THE SYSTEM
The EAGLE PRO TWP Series torque wrench pump is connected to various EAGLE PRO torque wrench
heads with a dual, high strength thermo-plastic hydraulic hose assembly complete with hydraulic couplers and
protective dust covers. Attach the hose assembly to the pump valve (top male and female outlets) by pushing the male coupler fully
into the female coupler. (See FIG D and FIG E).
Male Coupler Female Coupler FIG D
EAGLE PRO INDUSTRIAL TOOLS, INC. FIG E
5 FORM NO. E09005 REV. A. While pushing the male coupler into the female coupler, rotate the locking collar on the female coupler so that
it screws onto the male collar. Ensure that the locking collar is firmly attached to the male coupler, when
properly tightened, the locking teeth on the collar will engage to prevent the coupler from coming loose. The
locking collar should only be hand tightened. See FIG F below.
Properly seated male and female couplers FIG F
IMPORTANT!
Ensure hydraulic connectors are fully engaged. Connectors not properly seated can leak and cause system
malfunctions.

ATTACHING PUMP TO TORQUE WRENCH HEADS
See the operators manual for your specific EAGLE PRO hydraulic torque wrench for detailed instructions on
assembling and setting up an EAGLE PRO hydraulic torque wrench.
Attach the dual, thermo-plastic hose to the torque wrench head. Ensure that both the male and female couplers
are properly seated. See FIG I.
Properly seated male and female couplers on Torque wrench head FIG I
3.3
SETTING SYSTEM PRESSURE/REQUIRED TORQUE
Once the torque wrench pump and torque wrench are properly assembled and connected, and the hydraulic
pump has a proper power supply, the pressure on the pump must be set. The amount of pressure the pump
provides ultimately dictates the amount of torque the torque wrench can produce.
Torque sequence may vary from location to location and it may even vary within a single location. There
are many variables that must be understood to achieve proper torque. Always abide by local procedures,
regulations and ASME PCC-1-2013 standards.
Each EAGLE PRO torque wrench is supplied with a pressure-torque conversion chart. See FIG J for an
example of the ESW torque wrench pressure-torque conversion chart.

FIG J
EAGLE PRO INDUSTRIAL TOOLS, INC. 8 FORM NO. E09005 REV. A. Below is an example of how to properly use the ESW Torque Wrench pressure-torque chart..
EXAMPLE
Application requires use of an ESW-3 EAGLE PRO hydraulic torque wrench to tighten a 1-1/2” bolt to 2100
Lb. Ft.
STEP 1. Locate the correct model of the torque wrench along the top of the pressure-torque chart
STEP 2. Read straight down the column until you find the closest figure to 2100. In this application it would
be 2164. 2164 is about 3% over the required torque value for this application.
STEP 3. From the figure of 2164, read all the way over to the left hand column of the chart, this will tell you
what pressure the pump must product to reach this torque value. In this case, to reach 2164 lb. ft. of torque
with the ESW-3 torque wrench, the torque wrench pump must product 6600 PSI.
As 2164 lb. ft. of torque is within the +/-3% accuracy range of the ESW-3 torque wrench, you could
leave the pressure at 6600 PSI. For higher precision, you should reduce the 6600 PSI by 3% to 6402
PSI.
3.4
SETTING PUMP PRESSURE
Now that pump pressure has been determined, follow the procedure below to set the pump pressure.
STEP 1. Loosen the lock ring on the “T” handle of the external pressure valve. Turn the “T” handle counter
clockwise until it moves easily.
STEP 2. Turn the pump on. Using the pendant control, push down on the
ADVANCE button and hold it.
T‐Handle STEP 3. While continuing to hold the ADVANCE button down,
slowly turn the “T” handle clockwise and watch the pressure rise on the pump
pressure gauge.
STEP 4. When the gauge reaches the required pressure (see example above to
determine required pressure) stop turning the “T” handle and allow the pressure
to stabilize.
STEP 5. If the pressure continues to rise above required pressure, release the
ADVANCE button and turn the “T” handle counter clockwise, this will reduce
system pressure. Press the ADVANCE button again and slowly bring the pressure up to the required pressure.
STEP 6. Once the pressure is correct, turn the pump off. Tighten the lock ring on the “T”
handle against the valve body. This will lock the “T” handle in place and prevent pressure
changes. This sets the pump pressure which ultimately determines the torque output of the torque wrench.
Cycle the pump one final time to ensure that the pressure is properly set.
IMPORTANT!
Do not adjust the pump pressure while the torque wrench is operating. Adjust the regulator so that the pressure
is increasing, not decreasing. If you have to lower pump pressure, start the pressure setting procedure from the
beginning.
EAGLE PRO INDUSTRIAL TOOLS, INC. 9 FORM NO. E09005 REV. A. 3.5
PUMP OPERATION —TIGHTENING
See the operators manual for your specific EAGLE PRO hydraulic torque wrench for detailed instructions on
assembling and setting up an EAGLE PRO hydraulic torque wrench.
With the EAGLE PRO torque wrench properly assembled and properly positioned on the work piece, follow
the procedure below.
STEP 1. Push down on the ADVANCE button of the pump pendant control. This will push the rear of the
tool backwards until the reaction arm comes into contact with the chosen reaction point. ENSURE ALL
BODY PARTS AND CLOTHING ARE FREE OF THIS AREA .
STEP 2. Hold down the ADVANCE button on the pendant control as the torque wrench continues to
operate. You will hear an audible CLICK once the torque wrench has reached its full extension.
If you continue to hold down the ADVANCE button at this point, the pump will continue to build
pressure to the preset pressure that was set earlier. This does not indicate that the proper torque has
been applied to the bolt/nut. It only indicates that the cylinder is extended and is unable to rotate
further until the torque wrench resets.
STEP 3. Release the ADVANCE button after hearing the audible CLICK. This will reset the torque
wrench. Once the torque wrench is reset, you will hear another audible CLICK. Each time the torque
wrench is advanced and reset in this manner is considered a CYCLE. In order to obtain the proper amount of
torque on the fastener, several CYCLES may need to be made until the tool stalls at the pre-set pressure/
torque. Always cycle the torque wrench one final time to make sure the stall point has been reached.
LOCK– ON
Should the torque wrench lock-on during operation, push down on the ADVANCE button to build pressure.
Continue to hold the ADVANCE button down and push the drive release lever down. Release the
ADVANCE button while continuing to hold the drive release lever down. This will allow the torque wrench
to be removed.
3.6
PUMP OPERATION —LOOSENING
Following the procedure in section 3.4 set the pump pressure to 9,000 PSI . Do not try to loosen bolt/nut
with pump set at full 10,000 PSI. Change the torque wrench to the loosening mode and properly position on
work piece.
Press and hold the ADVANCE button on the pendant control. Pump pressure will decrease as the bolt/nut is
loosened. Once the cylinder is fully extended you will hear an audible CLICK. Release the ADVANCE
button and the torque wrench will reset. Once the torque wrench is reset, you will hear an audible CLICK.
Continue to CYCLE the torque wrench until you can remove the fastener by hand.
IMPORTANT!
If the fastener does not loosen with the above procedure, you must select a larger torque wrench to remove
the fastener.
EAGLE PRO INDUSTRIAL TOOLS, INC. 10 FORM NO. E09005 REV. A. 04 MAINTENANCE
IMPORTANT!
In order to ensure proper operation of the electric pump, completely drain and clean the pump reservoir every

yellow and transparent liquid. If hydraulic fluid appears dark or cloudy replace the fluid.
4.1
CHANGING THE HYDRAULIC FLUID
Follow the steps below to change the hydraulic fluid.
STEP 1. Ensure pump is unplugged from power source and system pressure has been released.
STEP 2. Unscrew and remove the reservoir oil fill plug.
STEP 3. Loosen reservoir drain plug using a 6mm hex wrench. See FIG K
Drain oil into approved container and dispose of properly according to local regulations.
STEP 5. Loosen the (4) 5mm hex socket bolts holding the roll cage to
the pump reservoir. Remove pump from roll cage
STEP 4. Unscrew and remove the (6 ) 5mm hex socket bolts holding
the reservoir to the top plate of the hydraulic pump.
STEP 5. Lift the top plate off of the pump reservoir, being careful not
to damage the pump body and set aside.
Reservoir Oil Drain Plug STEP 6. Clean the pump reservoir with a mild cleaning agent and
wipe dry. Ensure that any small pieces of paper towel or rag
are removed from the reservoir.
FIG K
STEP 7. Unscrew the oil filter by hand from the pump body and clean
using a mild cleaning agent and a soft brush. Flush the filter with clean hydraulic fluid to ensure any
cleaning agents and/or small particles have been removed from the filter. If the oil filter is damaged
contact the nearest authorized Eagle Pro service center to order a replacement.
STEP 8. Screw oil filter back onto pump body, be sure to only hand tighten oil filter. Over tightening may
damage the pump body.
STEP 9. Reassemble pump and reservoir and place back into roll cage, and secure assembled pump to roll
cage.
STEP 10. Once pump is completely assembled, add new, clean ISO #32 hydraulic fluid, see Section 02
