1.6 Laser Classification
1.6.1 General
The following chapters provide instructions and training information about laser safety according
to international standard IEC 60825-1 (2014-05) and technical report IEC TR 60825-14
(2004-02). The information enables the person responsible for the product and the person who
actually uses the equipment, to anticipate and avoid operational hazards.
☞According to IEC TR 60825-14 (2004-02), products classified as laser class 1,
class 2 and class 3R do not require:
•laser safety officer involvement,
•protective clothes and eyewear,
•special warning signs in the laser working area
if used and operated as defined in this User Manual due to the low eye hazard level.
☞National laws and local regulations could impose more stringent instructions for the
safe use of lasers than IEC 60825-1 (2014-05) and IEC TR 60825-14 (2004-02).
1.6.2 Zone80 DG
The rotating laser built into the product produces a visible laser beam which emerges from the
rotating head.
The laser product described in this section is classified as laser class 1 in accordance with:
•IEC 60825-1 (2014-05): “Safety of laser products”
These products are safe for momentary exposures but can be hazardous for deliberate staring
into the beam. The beam may cause dazzle, flash-blindness and after-images, particularly under
low ambient light conditions.

2 Description of the System
2.1 System Components
The Zone80 DG is a laser tool for general construction, levelling and slope applications such as:
•Setting forms,
•Agricultural levelling applications,
•Levelling to grade,
•Controlling grade levelling,
•Controlling depths for excavations.
If set up within the self-levelling range, the Zone80 DG automatically levels to create an accu-
rate horizontal, vertical or sloped plane of laser light.
Once the Zone80 DG has levelled, the head starts rotating and the Zone80 DG is ready for use.
30 seconds after the Zone80 DG has completed the levelling, the H.I.Alert system becomes
active and protects the Zone80 DG against changes in elevation caused by movement of the tri-
pod to ensure accurate work.
1
2
3
The Zone80 DG is a dual grade laser;
it produces an accurate plane of laser
light for applications which require
level (1), single slope (2) or dual slope
(3).

2.4 Setup
•Keep the location clear of possible obstructions that could block or reflect the laser beam.
•Place the Zone80 DG on stable ground. Ground vibration and extremely windy conditions
can affect the operation of the Zone80 DG.
•When working in a very dusty environment place the Zone80 DG up-wind so the dirt is
blown away from the laser.

matically levels to create an accurate horizontal plane of laser light.
•Once levelled, the head starts rotating and the Zone80 DG is ready for use.
•The H.I.Alert system becomes active 30 seconds after completing the self-levelling. The
H.I.Alert system protects the Zone80 DG against changes in elevation caused by any move-
ment or settling of the tripod.
•The self-levelling system and the H.I.Alert function continue to monitor the position of the
laser beam to ensure consistent and accurate work.

3.6 Conversion of Slope Into Percent of Grade
Slope: The change in elevation per unit of measure (foot, metre, etc.)
Percent of Grade: The change in elevation per 100 units of measure (feet, metre, etc.)
Calculating percent of grade from slope:
[Slope] x 100 = [Percent of Grade]
Example:
