Operation
The following description applies to the operation of hydraulic
torque wrenches.
4.1
Torque adjustment (Fig. 4)
• Connect Hydraulic Power Unit to the power supply.
• Switch on power switch (N), wait for self-test.
• Turn lock (R) of pressure adjusting valve (2) counter-
clockwise.
• Press and hold button (M). Simultaneously turn pressure
adjusting valve (2) until the working pressure in accord-
ance with torque table of the tool is indicated on gauge (1).
• Release button (M). Turn lock (R) of pressure adjusting
valve (2) clockwise (anti-twist protection).
4.2
Remote Control
• Button (M) for manual operation
• Button (A) for automatic operation

4.2.1 Manual operation (Fig. 5)
• Switch on the pump (N), wait for self-test.
• Torque setting according to section 4.1.
• Press and release button (M) repeatedly to trigger a rotating
movement of the hydraulic torque wrench drive.
• Press button (M) repeatedly, until the hydraulic wrench
stops rotating and the pressure gauge (Fig. 4, item 1) in-
dicates, that the set working pressure or torque has been
reached.
If the hydraulic torque wrench stops rotating, the
hydraulic piston may be at the stop limit.
Press the button (M) once or twice again!
This will ensure that the applied torque has been
transferred to the bolted connection.
As soon as the hydraulic piston of the torque
wrench stops, release button (M). This avoids an
overload of the motor, leading to a possible safety-
related shut-down.
4.2.2 Automatic operation (Fig. 5)
• Switch on the pump (N), wait for self-test.
• Torque setting according to step 4.1
• Press and hold button (A) for automatic operation of the FB
NOVA remote control. The wrenching process will start. The
correct working pressure or torque has been reached, as
soon as the hydraulic torque wrench stops rotating.
• Finally release button (A) after repeated build-up of the set
working pressure.
If the hydraulic torque wrench stops rotating, the
hydraulic piston may be at the stop limit.
Press the button (M) once or twice again!
This will ensure that the applied torque has been
transferred to the bolted connection.
Observe the safety function!
If button (A) in automatic operation, or button (M)
in manual operation, is being released during the
wrenching process, the piston rod of the hydraulic
cylinder retracts. The alkitronic® NOVA Hydraulic
Power Unit will shut-off after approximately 3-5
seconds. When the button is pressed once more, the
unit will switch on again.
