General Safety Precautions

1. Whenever servicing the platesetter, post the following sign close to the keyboard and close to the platesetter: caution: machine in service - do not operate. This sign will caution people from operating the platesetter while it is being serviced.
2. Many service procedures can be performed when the entire platesetter or some of its assemblies are switched off. Service the platesetter when off whenever possible (see Disconnection from Mains Supply further on).
3. You are not allowed under any circumstances to defeat any Laser interlock !
4. While taking appropriate precautions, you are allowed to defeat the Drum and other motor interlock switches. Do so only when no alternative service option is possible.

Important Note: If you must defeat the motor interlocks, you are not allowed to use any other means except the dedicated cheaters (Scitex No. 290B8L064) that were supplied for the use of the Lotem 800 service. Use of any other interlock cheater is forbidden.

5. Three readily accessible yellow pushbuttons are provided for disconnecting power from the mechanical hazards existing in the platesetter. Two identical On/Off pushbuttons are located on the external rear side, on both sides of the Plate unloading opening; these disconnect power from the platesetter units, but not from the fans.

Another pushbutton is centrally located below the Upper front door; it activates the motor interlocks, even if the interlock is defeated. When the pushbutton is pushed, power is disconnected from the motors, including the drum motor. However, since the drum motor has inertia, it may take a minute or so for the revolving drum to stop (this applies to the platesetter main circuit breaker as well).

Injury hazard! The drum will not stop immediately when the yellow on/off pushbutton is pressed or the main power circuit breaker is activated.

6. Prior to service, remove any piece of clothing or object that may get caught in the revolving drum or in any other moving part of the platesetter. For example, remove ties, roll up long sleeves, remove rings and bracelets, and gather long hair.
7. Remove jewelry, wristwatches and reflective objects from your hands, wrists and shirt, and use non-reflective tools. This measure reduces the chance of hazardous laser reflection if a failure occurs in the Laser interlock system or in a protective barrier.
8. If there is any doubt regarding the proper functioning of the Laser interlock system, or whenever you suspect that the platesetter protective cover or barrier is broken, cracked or otherwise damaged, you must turn the platesetter off and not turn it on again until it is checked and found to be OK.
