Feeler gauge 0.6 mm
Preparatory steps
X Remove the Twin Head from the machine (see service manual).
WARNING: The safety instructions in the chapter Operational Safety in the operating and
service manual take priority.
X The SIPLACE machines are supplied with line voltage.
Parts of the system therefore carry dangerously high voltages! In specific modules the
voltage is present inside the machine base even when the main switch is turned off.
Handling the machines improperly or touching parts thereof which conduct high voltage may
result in death or serious physical injury as well as extensive property damage.
Before you perform any work on the machine, shut down the operating system and then
ensure that the machine is switched off at the main switch and is disconnected from the power
supply .
X In addition, the compressed air supply must be turned off at the main valve of the compressed
air unit, in the machine base, and the compressed air lines must be bled by actuating the
needle valve on the compressed air unit.
X The area around the linear motors presents a risk of lethal injuries to persons wearing heart
pacemakers. Observe the instructions in Chapter "Special safety instructions for working in
the vicinity of powerful magnetic fields" in the operating and service manuals.
X Observe the applicable accident prevention regulations, DIN standards and special safety
codes of your country at all times.
X Read and observe the instructions about residual voltages in Chapter "Operational Safety".
X Always observe the ESD regulations described in Chapter "Operational Safety" of the
operating guide.
X While performing retrofitting work, always secure the machine to prevent unauthorized
reactivation or access by unauthorized persons, as described in Chapter "Locking the
Machine... ".
X There is an additional, high risk of accidents when working with the SITEST program.
SITEST may therefore only be started by specially authorized and trained persons.
