- operate the machine in high humidity conditions (more than 80 %), as well as outdoors.
3.6. Take care to protect the machine against blows, overloads, dirt and petroleum product exposure when operating.
3.7. Switch off the machine using the circuit breaker in case of a sudden stop (due to the voltage loss, seizure of moving parts, etc.).
 
4. Preparing the machine to operation
4.1. In case of machine transportation or storage in high humidity or low temperature conditions, keep it at the temperature of 20 ± 5°C for 5 hours.
Range of working temperatures: +5 to + 40 °C
4.2. Machine start procedure:
- make sure that the voltage in the mains supply corresponds to the specifications and does not exceed it by more than 10 V;
- set the circuit breaker to the "off" position;
- inspect and ensure the proper insulation of the power cable and connect it to circuit breaker terminals in the correct sequence.
 
Warning!
Ensure the direction of motor rotation is clockwise during the phase connection. 
 
- connect the power cable to the network;
- connect the drive pedal to the connector (located under the protective cover);
- set the circuit breaker in the "on" position;
- ensure the forward movement of the hydraulic power cylinder rod by pressing the drive pedal.
4.3. Machine stop procedure:
- stop pressing the drive pedal, then the actuating hydraulic cylinder rod will return to the initial position;
- remove any metal blanks from machine actuators;
- set the circuit breaker to the "off" position;
- unplug the network cable from the mains.
 
Warning!
Reset the press not earlier than 30 seconds after shutdown.
 
5. Machine operating principle
    First of all, the machine is prepared to operation depending on what kind of texture or decorative item is needed.
Select the same die pairs and mount them on the ways in case of forming and texture applying operations, and on the tables when performing decorative bending (see installation and operation procedure below).
Use the pedal to actuate the motor connected to the gear pump via clutches. It supplies oil from the hydraulic tank to the pump to build pressure and transmit it into the parallel hydraulic cylinder. The hydraulic cylinder rod starts translational movement transmitted to the sliding table with the dies fixed on it (for forming or texture applying operations) or the punch (for decorative bending operations). The second die part is rigidly attached to the fixed table. Then the dies approach each other with the workpiece set on the adjustable stop pre-set to the desired position. The dies begin compressing the workpiece in certain forms, while the operator must rotate the workpiece or pull/push it after each compression depending on the result required. The metal changes its shape to achieve a certain pattern corresponding to the outer die pattern.
 
6. Bar stock bending operation 
Follow these steps for bar stock bending:
6.1. Cut the bar to a required length (use Steel 0 - 3 only).
6.2. Install additional devices (see Fig. 2) according to marks on the die. 
6.3. Place the workpiece on the fixed table (see Fig. 3).
6.4. Press the pedal and hold it until you obtain a desired item.
Note: it is recommended to grease the working surfaces of the punch and die with "Litol" or "Solidol" lubricants in order to reduce punch and die wear and work hardening on the finished item.
 
Warning!
To avoid injury during the bending operation it is NOT REQUIRED to HOLD THE WORKPIECE – it must be in a free state when the sliding table is moving.

7. Applying texture to the bar stock and forming operations
 
Depending on the purpose and finished product, dies are divided into forming ones and that used for applying texture on bar stock.
The procedure of mounting devices and operation steps are identical for the operations of forming and applying texture on bars. 
To perform these operations proceed as follows:
7.1. Cut the workpiece to the required length (use Steel 0-3 only).
7.2. Install additional devices as shown in Fig.4.

Note: install dies against stop 5; insert 11 is used for convenient handling of 8-16 section rolled steel; it is mounted after moving sliding table 3, between the wall of the end of the working unit and the end of the sliding table as shown in Fig. 4.
 
Warning! 
It is not recommended to install a pair of dies with different patterns.
When performing hot operations, observe the operation mode (30 minutes work / 30 minutes break ) to avoid removing the hardening (self-tempering) of die steel.
7.1. Adjust stops 6 relative to bar workpiece section; refer to Fig. 4 for the distance to the die center.
7.2. Position the workpiece between dies 9 and 10 at stops 6.
7.3. Press the pedal and hold it until you obtain the item.
