Accuracy Adjustment

• It is the responsibility of the user to follow operating instructions and to
periodically check the accuracy of the laser and work as it progresses.
• The Rugby is adjusted to the defined accuracy specification at the factory. It is
recommended to check the laser for accuracy upon receipt and periodically
thereafter to ensure accuracy is maintained. If the laser requires adjustment,
contact your nearest authorised service centre or adjust the laser using the proce-
dures described in this chapter.
• Only enter the accuracy adjustment mode when you plan to change the accuracy.
Accuracy adjustments should only be performed by a qualified individual that
understands basic adjustment principles.
• It is recommended to perform this procedure with two people on a relatively flat
surface.
