Accuracy Adjustment

• It is the responsibility of the user to follow operating instructions and to periodi-
cally 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 there-
after to ensure accuracy is maintained. If the laser requires adjustment, contact
your nearest authorised service centre or adjust the laser using the procedures
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.

completely (approximately 1 minute after the Rugby begins to rotate).
3. Mark the position of the beam.
4. Rotate the laser 180° and allow it to self-level.
5. Mark the opposite side of the first axis.
