Figure 3, Oil Fill Plug
4.3 Oil Level (See Figures 3 and 4)
Check the pump oil level prior to start-up. The reservoir is full
when the oil level is as shown in Figure 4. If necessary, remove
the oil fill plug from the cover plate as shown in Figure 3 and add
oil as required.
IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.

4.4 Electrical Connections
WARNING: The pump is factory equipped with the
common electrical plug for a given voltage. Altering the
plug type should only be done by a qualified electrician,
adhering to all applicable local and national codes.
1.
The disconnect and line circuit protection is to be provided
by customer. Line circuit protection is to be 115
full load current at maximum pressure of application.
2.
For more information, refer to pump name plate for
power rating.
4.5 Hydraulic Hose Connections
Connect hoses as shown in Figure 5.
Use hoses rated at 10,000 psi/700 bar operating pressure.
Couplers must be polarized per Figure 6 for correct wrench
operation. Ensure couplers are fully engaged and tightened
before operating. Partial coupler engagement will prevent proper
wrench operation.

WARNING: When using pumps with multi-wrench
manifolds, ensure all unused couplers have the
protective caps fully installed before starting pump.
Note: When the wrench is first connected to the pump, air will be
trapped in the hydraulic circuit. Remove air by placing wrench
and straightened hoses below pump. Operate wrench without
load as required, until it advances and retracts without hesitation.
5.0 OPERATION
1.
Be sure that the air breather and adapter fitting have been
installed. See Section 4.2.
2.
Check the pump oil level and add oil if necessary. See
Section 4.3.
3.
Connect unit to power. Wait until "READY" is displayed on the
LCD before pressing any button on shroud or pendant.
Note: During the boot sequence, the microcontroller identifies any
button operation as a potential malfunction and prevents the motor
from starting. Reset by disconnecting power for 20 seconds.
4.
Set the relief valve pressure. See Section 5.2.
5.
Using the LCD control panel, set the desired maximum
advance pressure or torque. Refer to sections 6.1 through 6.5
of this document for LCD control panel operation instructions.
WARNING: As motor starts, the torque wrench will
retract automatically. Verify torque wrench is positioned
to
avoid
starting motor.
6.
Start motor and retract wrench by pressing and releasing the
pendant on/off button. The LCD will show the pressure in the
retract circuit (B-port bypass), approximately 2500 – 2800 psi
[173 – 193 bar].
7.
Advance the torque wrench by pressing and holding the
pendant advance button.
8.
Shut-off motor by pressing the pendant on/off button or the
shroud on/off (Motor) button. If no pendant or shroud buttons
are pressed within any continuous 20 second period, the
pump's built in timer will automatically shut-off the motor.
Note: When the motor is turned off, as the motor stops turning,
the valve will automatically cycle to release all pressure in both
the advance and retract hoses.
Note: Pumps equipped with heat exchangers: Whenever
possible, allow the timer to automatically shut-off the pump.
The 20 second delay will allow additional time for oil to circulate
through the heat exchanger, resulting in improved oil cooling.
700 BAR/10,000 PSI MAX.
