 Set the pressure so that the ends of the work pieces can again be lain uniformly and nearly
pressure-free onto the heating element.
A signal sounds shortly before the end of the warm-up time.
 After the warm-up time is over, separate the work pieces, remove the heating element and
bring the work pieces back together.
 Stop the bringing together process by releasing the buttons shortly before the ends of
the workpieces make contact (about 1 cm.) and press the buttons again immediately. The
pressure is linearly raised to the appropriate joining pressure.
When joining pressure is reached, the program automatically goes to the joining process and
the t4 timer starts.
The upper progress bar shows whether the pressure lies within the correct range (green) or
within a permissible (yellow) tolerance range or whether it lies outside (red) the tolerance
range. The time lapse is shown below. The actual pressure is shown in display (2) and the
remaining joining time in display (9).
Attention: Hold down the Release button (10) and the Close machine button (11) until the
joining pressure is reached. Then the hydraulic unit shuts off and the buttons can be released.
 The pressure is monitored and automatically regulated again. If the hydraulic system repumps
too often (meaning there is high pressure loss), have it checked.
