WARNING

Watch out for erroneous measurement results if the product has been dropped or has been misused, modified, stored for long periods or transported.

Precautions:

Periodically carry out test measurements and perform the field adjustments indicated in the user manual, particularly after the product has been subjected to abnormal use and before and after important measurements.

Because of the risk of electrocution, it is dangerous to use poles and extensions in the vicinity of electrical installations such as power cables or electrical railways.

Precautions:

Keep at a safe distance from electrical installations. If it is essential to work in this environment, first contact the safety authorities responsible for the electrical installations and follow their instructions.

With the remote control of products, it is possible that extraneous targets will be picked out and measured.

Precautions:

When measuring in remote control mode, always check your results for plausibility.

If the product is used with accessories, for example masts, staffs, poles, you may increase the risk of being struck by lightning.

Precautions:

Do not use the product in a thunderstorm.



WARNING

CAUTION

WARNING

1.6 Laser Classification

1.6.1 General

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.



1.6.2 Rugby 870/880

General The rotating laser built into the product produces a visible laser beam which emerges

from the rotating head.

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).

The 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.



WARNING

The greyed paragraph below is only applicable for products without radio.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and the receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Changes or modifications not expressly approved by Leica Geosystems for compliance could void the user's authority to operate the equipment.

2 Description of the System

2.1 System Components

General description The Rugby 870 and the Rugby 880 are laser tools for general construction, levelling

and slope applications such as

•Setting forms,

• Levelling to grade,

• Controlling depths for excavations.

If set up within the self-levelling range, the Rugby automatically levels to create an accurate horizontal or vertical (Rugby 880 only) or sloped plane of laser light. Once the Rugby has levelled, the head starts rotating and the Rugby is ready for use. 30 seconds after the Rugby has completed the levelling, the H.I.Alert system becomes active and protects the Rugby against changes in elevation caused by movement of the tripod to ensure accurate work.

Area of application Single grade

The Rugby 870 is a single grade laser; it produces an accurate plane of laser light for

applications which require level (1) or single slope (2).

Available system components

Dual grade

Rugby 870/880

The Rugby 880 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

Location • Keep the location clear of possible obstructions that could block or reflect the laser

beam.

• Place the Rugby on a stable ground. Ground vibration and extremely windy conditions can affect the operation of the Rugby.

• When working in a very dusty environment place the Rugby up-wind so the dirt is blown away from the laser.

Setting up on a tripod

007822_001

Step Description

1. Set up the tripod.

2. Place the Rugby on the tripod.

3. Tighten the screw on the underside of the tripod to secure the Rugby on the tripod.

• Attach the Rugby securely to a tripod or laser trailer, or mount on a stable level surface.

• Always check the tripod or laser trailer before attaching the Rugby. Make sure all screws, bolts and nuts are tight.

• If a tripod has chains, they should be slightly loose to allow for thermal expansion during the day.

• Secure the tripod on extremely windy days.

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:

Slope = 0.0059 Conversion = 0.0059 x 100 Percent of Grade = 0.590%

3.7 Alignment of the Axes

Aligning X- and Yaxis

After the desired grade is correctly set in the display, align the X- and Y-axis to the jobsite.

The direction of the X-Axis is seen from the front of the Rugby, sighting over the top of the Rugby.

Rotate the Rugby slightly until the alignment marks are aligned with your second control point. Once the Rugby is aligned, you can start working.

Ensure that the bubble of the circular level is positioned near the centre of the circle for maximum self-levelling capability.

Ensure that the Rugby is properly positioned over a control point.

3.8 Precise Alignment of the Axes

Precisely aligning Xand Y-axis

Under most conditions, the raised alignment marks on the top of the Rugby are adequate for alignment of the axes. For a more precise alignment, you can use the following procedure. Objective of a precise alignment:

• To establish Point A on the Y-axis as a reference and take an elevation reading.

• To enter grade into the X-axis and then adjust the position of the laser until the original elevation at Point A is again found.

Step Description

1. With 0.000% grade in both axes, set up the Rugby directly over a grade stake and roughly align the Y-axis to a second grade stake (Point A).

2. Take an elevation reading at Point A using a Rod Eye receiver and a survey rod.

3. Enter +5.000% grade into the X-axis. When grade is entered into the X-axis,

the Y-axis acts like a hinge or fulcrum.
