this will automatically self level the laser and power up all the laser dots at
the same time.
For the D272R and D272G models you will see two laser dots one plumb up
and one plumb down.
The D273R and D273G models will produce 3 dots, the plumb up and down
plus a horizontal level dot.
The D275R model produces 5 dots, plums up and down plus 3 horizontal

D27xxTM TROUBLE SHOOTING
• Keep laser and accessories stored in protective case.
• Make sure laser is stored dry, dry out before storage to prevent damage.
• Remove batteries when not used for an extended period of time to prevent
leakage. (battery leakage not covered by warranty)
• The D27xx models are precision instruments and should not be subjected to
excessive knocks, drops or vibrations.
• Self check calibration from time to time. See below
• For service contact Redback Lasers. www.redbacklasers.com.au
Care & Maintenance
Calibration & Self Check
All Redback Lasers have been checked for calibration and certied by one of
our technicians here in Australia prior to despatch and should under normal
conditions not go out of calibration. A calibration certied sticker with the
date and name of technician is located on the laser itself. It is worth checking
calibration from time to time particularly after any known knocks or drops.
An easy way to continually check calibration is to always double check you
work with the laser located in a dierent position or use an alternate vertical
line. Various other methods for checking calibration can be found at www.
redbacklasers.com.au/downloads or the laser can be returned to our
service department for checking and re-calibration.
