Ambient conditions C – 35 Ambient temperature 45 % – 65 % Air humidity The * data are theoretical/computed values, or values measured on a prototype. Actual values may vary slightly, depending on the ma- chine. The use of special hydraulic oil with improved properties and addi- tives can prolong the service life of the machine and extends the oil change interval.
Transport and commissioning Transport The goods should be transported in the original packaging. During transport, the goods must be secured safely within the packaging. All applicable laws and regulations relating to securing loads shall be ob- served during transport. The machine/unit may only be unloaded and transported by means of a forklift, a lift truck or a crane.
WARNING! Danger from falling loads! Risk of injury from falling loads. • Do not stand under suspended loads. WARNING! Danger from tilting machine/unit! The machine/unit may tilt if it is transported improperly. There is a risk of being injured. • Consider the machine/unit's centre of gravity (1).
WARNING! Risk by tilting machine! If not bolted to the floor, the machine may tilt. There is a risk of being injured. • Fix the machine on the floor. Use suitable bolts to fix the machine legs on the floor. Place the machine in a way so that it is easily accessible for main- tenance work from all sides.
Page 35
CAUTION! Risk of injuries! Contact with hydraulic oil and other consumables imposes a risk of injuries for the skin, eyes, respiratory and intestinal tracts! Hy- draulic liquid spills impose danger of slipping and falling! • Observe supplier's protection and safety instructions (see data sheet).
Mount grating (1). Do not operate the machine for a minimum of four hours so that the dirt particles in the system may settle. 4.3.2 Electrical connection ATTENTION! Risk of damage to machinery The voltage range described in this Section is only permissible for multi-voltage machines (MVA).
Page 37
Place the voltage selection plug on the correct slot in the control cabinet - Δ 230 V at the bottom connection (3), Υ 400 V at the top connection (2). Set the motor protection switch (1) as specified in the Technical data.
Page 38
ATTENTION! Risk of damage to machinery! Extended operation of the motor with an incorrect rotational di- rection or operating the machine without oil will destroy the hyd- raulic pump. • Make sure that the hydraulic oil filling in the machine is suffi- cient before starting the machine.
4.3.3 Bleeding the hydraulic system Switch on the machine. Operate the machine in the idle mode for two minutes in order to fill the pump with oil. Open and close the tool several times. Check oil level, add hydraulic oil if required.
Operation What you have to observe The operator has received the Operation Manual from the owner, has read and understood it and will observe it. Before starting and/or re-starting • Ensure sufficient illumination of the working area of the ma- chine/unit.
Forming the workpiece 5.3.1 Prerequisites Prerequisites for a correct forming process: • The die system and the workpiece match each other. • The proper jaw system is correctly mounted in the tool. • The forming dimension and the dies have been entered in the control system, please also refer to "Setting the forming dimen- sion"...
Page 42
WARNING! Risk of squeezing! When the die system closes, there is a risk of getting squeezed between the die and the workpiece. • Keep the feed opening for the workpiece as small as possi- ble. • Keep a minimum distance of 120 mm (A) to the die system. Press the button to activate the dual foot switch.
5.3.3 Operation mode buttons control panel WARNING! Risk of squeezing! When the die system closes, there is a risk of getting squeezed between the die and the workpiece. • Keep the feed opening for the workpiece as small as possi- ble.
actual dimension and the specified dimension (see “Setting the forming dimension” in Section 5). Open the crimping tool only so much that the hose may be placed and/or removed easily. Excessive opening means risk of squee- zing and time loss. 5.3.4 Remote automatic mode, via depth stop WARNING! Risk of squeezing!
Page 45

Changing the crimping dies 5.4.1 Changing the crimping dies using a die wrench Positioning the crimping dies Close the crimping tool until the holes (5) are visible for using the locking bolt. Switch off the machine using the main switch and secure it against switching on unintentionally.
Page 47
Place the crimping dies into the mounting hole (4) using the retaining bolt (2). Remove the die wrench (3) to release the pressure on the lo- cking bolt - the crimping die is now fixed. Always use a complete set of equal crimping dies with the same identification and diameter.
Replacing the intermediate dies Position the intermediate dies Close the crimping tool until the holes (5) are visible for using the locking bolt. Switch off the machine using the main switch and secure it against switching on unintentionally. WARNING! Risk of squeezing! When the die system closes, there is a risk of getting squeezed between the dies.
Page 49
Remove the die wrench (3) to release the pressure on the lo- cking bolt - the intermediate die is now fixed. Always mount a complete set of identical intermediate dies with the same label and diameter. Removing the intermediate dies Close the crimping tool until the holes (5) are visible for using the locking bolt.
Page 50
ATTENTION! Risk of damage to machinery! If the profile 266/268/237 intermediate dies (1) are placed in the tool by means of crimping dies PB 239 and QDC 239, the base dies, the locking bolts in the base dies as well as the retaining bolts of the intermediate and criming dies will be destroyed.
5.5.1 Changing the crimping dies with the quick die change system (only profile 239) Select the change position for crimping dies in the control by ac- tivating the button [QDC]. Press the button to open the crimping tool so that the dies type PB239 can just be inserted.
Page 52
ATTENTION! Risk of damage to machinery! The retaining bolts and the crimping dies will be destroyed if the retaining bolts do not fit in the mounting hole of the base dies or intermediate dies. • Pay attention to the correct position of the quick die change system with crimping dies.
ATTENTION! Risk of damage to machinery! If the crimping dies protrude beyond the basic and intermediate dies, the crimping dies, the intermediate dies and the machine will be damaged (see (X) in the figure). In the figure, the crimping die (2) is placed incorrectly. •...
(8) Connection cable with plunger switch (9) Sleeve Setting the forming dimension The forming dimension (X) must be set specifically for the workpiece. Read the forming dimension in the forming dimension table of the system supplier, e.g. Ø 17.4 mm. Select crimping dies with a smaller or the same diameter, e.g.
machines without any forming distance limitation, tools components may be damaged if the forming range is exceeded. Stop Complete the forming process. Deposit the work piece outside the machine. Deactivate the main switch (1). Check the machine for contamination, leaks and external da- mage.
5.10 Emergency stop In case of an emergency Immediately press the emergency-stop button (1) in cases of emergency. The crimping tool movement will be stopped. The drive unit is shut down. Restart after and emergency WARNING! Risk of injuries! The emergency-stop button was probably activated due to the occurrence of a hazardous situation.
