7-2. Maintenance Checklists

Perform daily and 6-month inspections for all F3SG-SR/PG. When using the F3SG-SR/PG in
cascade connection, perform inspections for every connected F3SG-SR/PG. Otherwise, the
system may fail to work properly, resulting in serious injury.
Do not try to disassemble, repair, or modify the product. Doing so may cause the safety functions
to stop working properly.
To ensure safety, keep a record of the inspection results.
When the user is a different person from those who installed or designed the system, he/she must be properly
trained for maintenance.

around the machine's hazardous part.
 The actual safety distance is equal to or greater than the calculated value.
 There must be no dirt on or damage to the front window or Spatter Protection Cover (F39-HSG, sold

 When the power of the F3SG-SR/PG is turned ON while nothing is in the detection zone, it must
operate as follows:
If Start Interlock is not used: The OSSD indicator turns green within 3 s after the F3SG-SR/PG is turned
ON.
