Basic Service Process

  1. Move the saw head all the way to the front of the machine and press the E‑stop button.
  2. Disable the blade motor as appropriate:
    • Safety PLC: Enter commissioning mode.
    • Safety relay: Remove power plug from motor and secure with electrical tape ensuring no interference is possible when the head rotates or bevels
  3. Allow the saw to be run with the door open as appropriate:
    • Safety PLC: Enter commissioning mode.
    • Safety relay: Bypass the door and all other guard interlocks.
  4. Start the Simple/PMAC backup and update procedure.

  5. As this is running, remove all guards while occasionally moving back to the monitor to keep downloading the PLCs. Leave all fasteners in their respective positions once the guards are off except for the Y‑axis centre brush cover and rear frame cover.

    Note: leave the dome, the Y‑axis centre brush cover and the 4 front screws on the Y‑axis centre brush cover until last.

  6. When the update process is finished, home the saw and lift the dome.

  7. Remove the last 4 screws of the Y‑axis centre brush cover and the cover itself.
  8. Turn on the dust extractor and thoroughly blow down the machine (including the electrical cabinets) using a top-down approach while on the lookout for any superficial damage.

  9. Grease the entire saw starting with the saw chamber and working around while performing as many of the more simple checks as you can remember from the checklist as you move through.

    Note: Also, be on the lookout for anything that looks incorrect or damaged. If you find something, note it down and keep greasing.

  10. Once the greasing is complete, go ahead and work through any remaining saw checks and feeder checks you can remember.

  11. Have a look through the Razer saw checklist from the Detailed Service Checklist only (saw chamber and feeders) and tidy up anything you have missed that requires the guards to be off. Leave the checks that require clamped timber to the very end.

    CAUTIONKeep in mind some actions require an E‑stop condition, so make sure the motor plug is in a safe location.

    Note: this is also a good time to isolate the air supply to perform all checks required without the air.

  12. Consider performing any minor remedial work required on the saw chamber and feeders that you wish to complete on the service.

    Note: major items that cannot fit into the time of the service should first be discussed with the site production manager.

  13. Refit all guards.
  14. Work through the remainder of the Detailed Service Checklist which can be done fairly sequentially (i.e. AIT, OFK, follower, printer and so on).
  15. Once all checks and minor repairs are complete, revisit the tasks that require clamped timber (e.g. rollers come down low enough, saw level, printer heights, thickness sensor, width sensor, etc.).
  16. Check the blade alignment if necessary.
  17. Perform the length calibration procedure and check follower zero offset.
  18. Remove all bypasses, exit commissioning mode and complete the cut calibrations.
  19. Get the operators to cut for as long as possible under full production (minimum 1 hour, ideally 2 hours), measuring every piece for 30 minutes. Make necessary tweaks where needed and answer any operator questions.
  20. Once done for the day, take a backup and put on Google Drive.
