Specified Conditions of Use
This device is exclusively intended for professional use as a drive mechanism for hydraulic torque tools in line with
the description and safety instructions given in these Operating Instructions.
 Any other use is considered to be improper!
 In particular the use of the machine as a drive for all other hydraulic devices such as presses, hoisting
cylinders, hydraulic shears, spreaders, etc. is improper use!
 Improper use of the device or modifications to the device undertaken by the end-user exclude any liability
on the part of the manufacturer and invalidate the Declaration of Conformity!
 In this case the user is liable for damages resulting from the use of the device.
Residual risks
 Danger due to hot surfaces: The surface of the oil cooler (if fitted)
becomes hot; keep a safe distance; the warning symbol is attached to the cooler
 Danger due to noise: maximum noise level 82 dB(A); the end-user must make personal protective
equipment (ear-protectors) available.
Notes on Transport
 Transport of the machine ready for operation:
a. by hand: up to 30 kg with 1 person
above 30 kg with two persons
b. with industrial trucks: use suitable hoisting equipment
c. hanging: use suitable slings (no chains, no metal ropes). Attachment
point for slings as shown in Figure 2
Fig. 2
Use and Conditions for Storage
 Ambient temperature: -10 to +40°C for use and storage
 Protect from rain during use and storage.
 Modification of the conditions of use only after consultation with the manufacturer.
 Power supply connections: (delivery with earthed pin plug). In the event of modification to the mains
connection, protection against shock must be guaranteed by installing a protective earth system.

Before Initial Operation
 Carry out a visual inspection before each start-up.
 Check remote control (1), mains plug (9) and all cables for damage.
 Check hose couplings, hoses1) and hydraulic torque tools1) for damage.
1) not included in delivery
 Hose couplings, hoses and hydraulic torque tools must be designed for an operating pressure of 700 bar.
 Hose couplings, hoses and hydraulic torque tools with lower operating pressures are not permitted to be
connected to the hydraulic device!
 Check the entire machine, fluid reservoir, motor, manometer and control box for damage such as
ruptures or leaks.
 Have damaged parts replaced by qualified technicians before operation.
 Check hose couplings (7, 8) for dirt.
 Clean soiled hose couplings before operation.
 Check the fluid level; the level must be up to the middle of the oil sight glass (6).
 If need be, top up hydraulic fluid.
 Set up the hydraulic device on a level, horizontal surface so that it is prevented from falling over or falling
down.
 Connect the hydraulic device by means of the threaded couplings with the hoses and with the hydraulic
torque tool: (as per Fig. 3)
 Power supply connections: (delivery with earthed pin plug). In the event of modification to the mains
connection, protection against shock must be guaranteed by installing a protective earth system.
Fig. 3
 The hydraulic device must not be operated without the hoses and the hydraulic torque tool connected
up!
 Connect the hydraulic device to the electricity supply.

Operation
Operating the Machine
 Switch on the motor by actuating the white push-button on the remote control (1).
 White push-button actuated: forward stroke of the tool piston
 White push-button not actuated: return stroke of the tool piston
 Switch off the motor by actuating the black push-button on the remote control (1)
 Relieve pressure of the device by manually actuating the solenoid valve (10)
Pressure and / or Torque Adjustment
The torque of hydraulic torque wrenches is proportional to the pressure.
This is why before tightening or loosening bolted connections the maximum pressure of the machine and
thus the maximum torque of the torque tool must be adjusted:
 Do not place the hydraulic tool on either bolts or nuts.
 Switch on the motor by pushing the white push-button on the remote control (1) and keep the white push-
button pressed down – the tool piston extends.
 After reaching the end position of the tool piston, the maximum pressure of the system can be increased
by turning the adjustment knob (4.1) on the pressure adjustment valve (4) clockwise until the required
pressure is reached. The current system pressure is displayed on the manometer (5).
 By releasing the white push-button, the tool piston retracts.
Fig. 4
 Checking the setting: after reaching the end position a second time, press the white push-button again in
order to extend the tool piston completely and to keep it until the maximum pressure is reached.
 To reduce the maximum pressure, turn the adjustment knob (4.1) on the pressure adjustment valve (4)
anti-clockwise.
 When the required pressure is reached, the setting is secured by tightening the wing nut (4.2) on the
pressure adjustment valve (4).
Tightening or loosening threaded connections
Tightening or loosening threaded connections is done according to the instructions of the torque tool
manufacturer.

Servicing and Fault Clearance
 As a matter of principle, electrical work may only be carried out by qualified electricians.
 Use only original spare parts as per the spare parts list.
 Hydraulic fluid change and filter change (if fitted) at least once every year or at the latest after every 300
operation hours; if necessary earlier, if the hydraulic device is used in a dusty environment.
 Recommended hydraulic fluids: HLP32 or HLP46
 Hydraulic fluid quantity : see Technical Data (Section 11)
 No Filling filter available! When filling, ensure that no dirt or foreign matter enters into the oil
container
 Fluid filter as per spare parts list
Malfunction
Possible cause
Remedy
Motor does not start
Mains cable not connected
connect Mains cable
Incorrect mains voltage
Check mains voltage; if
necessary connect
to suitable electricity supply
Mains cable faulty
Remote control cable faulty
Remote control faulty
Have it replaced by qualified electrician
Machine faulty
Have it serviced by authorised workshop
No (or insufficient) pressure
build-up even though motor
is running
Too little or no hydraulic fluid
Top up hydraulic fluid
Maximum pressure not set or
set too low
Adjust pressure as per Section 8
.2
Machine faulty
Have it serviced by authorised workshop
Tool does not move even
though pressure builds up
correctly
One or several hose couplings
not tightly connected
Connect up machine,
hoses and tool as per
Section 7, Fig. 2
Tool works the wrong way
round
Tool connected incorrectly
Connect up machine, hoses and tool as per
Section 7, Fig. 2
Shutdown
 Switch off motor by actuating the black push-button on the remote control (1).
 Release the pressure in the system by pressing the manual operation of the solenoid valve (10).
 Disconnect the hydraulic device from the mains.
 Turn the adjustment knob on the pressure adjustment valve (4) all the way anti-clockwise and thus set
the maximum pressure to 0 bar.
 Disconnect the hydraulic device from the hoses.
