article L 233-5 of the Labor Code, to ensure the safety of the user.
This press has been designed for an operator working in front of the machine.
USE
It is recommended to read the "instructions for use" carefully before starting any pressing operation.
The press must be used by an authorized person who has been informed of the risks that may be
caused by misuse of the equipment.
The adjustments (pneumatic, electrical and mechanical) made by our technicians in the workshop as
well as the safety devices installed on the machine must not be modified under any circumstances.
Otherwise, the company SEFA will release all responsibilities on possible problems related to the said
machine.

When handling, ensure that the operator does not risk anything in terms of burns, electrocution or
other.
Perform a daily inspection of the machine before starting production.
In the area around the machine, make sure there is no one before starting.
If the machine does not work properly, switch off the power supply immediately and look for the
cause (see chapter "Maintenance" in the manual).
c) Safety features on the machine
Protections and safety devices must not be modified.
They must be reassembled in case of possible removal for maintenance.

The energy mode has two settings: a long standby setting and a short standby setting.
The long standby mode puts the machine into hibernation for the time defined by the two
parameters. The temperature is then turned off, it will drop to room temperature. (No energy
consumption). If the machine is in automatic mode, it stops at the set time. The program displays the
idle page to indicate that it is paused. The brightness decreases and oscillates slightly. This mode also
allows an early start of the heating, for example before taking post. For this, it is necessary to leave the
machine under tension.
