Rugby 320 SG Introduction4
1 Introduction
The Rugby Grade laser is designed to serve your needs in a wide variety
of applications.
It is a proven tool for increased production with substantial reduction of
labor, time and material costs. It can be used to accurately control land
leveling, sloped or level grading, trenching, open cut mining, dredging,
contouring of levees, general construction and excavation.
This manual contains operating and set-up procedures for common
applications. Its purpose is to describe the features of the Rugby and
how the Rugby operates. The manual is not intended to describe specific
applications. Contact your local dealer or Leica Geosystems for informa-
tion specific to your jobsite requirements.
The Rugby Grade lasers are rugged, accurate and fully electronic with an
operating range up to 3000 feet (900 meters) diameter.
The Rugby 320 SG is a single grade laser and is capable of producing an
accurate plane of laser light for applications that are level (1) or having
a single grade (2).
Alignment is as easy as sighting over the top of the Rugby to your control
point using the integrated alignment sights or the optional sighting
scope assembly. For increased accuracy, follow the procedure for "3.5
Precise Alignment of the Axes".

Up and Down buttons simultaneously while in either grade entry mode.
When changing grade using the direct entry method, the counter will
always stop at zero. Release the button and press again to continue
counting beyond zero.
Grade Capability The Rugby 320 SG can have up to 25.000% grade in the X-axis.
The Y-axis does not have grade capabilitiy, and is a “level only” axis.
)If no button is pressed, the display will revert to the main display after
ten seconds.
Press POWER to turn the Rugby on.
Press Xto enter X-axis grade mode.
Use the UP or DOWN buttons to set the desired grade.
Press Xto exit.
While in the grade entry screens, press the STAR button and a
cursor will appear on the +/- sign.
Press the STAR button to move the cursor to the right.
Press the UP or DOWN buttons to change the sign or the digit
that is highlighted.
Press Xto exit.

Rugby 320 SG 7Operation
Grade Swap The grade in the X-axis can easily be swapped from positive to negative
in the Grade Entry by Digit screen.
Align the Y-axis (level) to the center line, the X-axis or cross axis grade
can be made to fall to the right or lefthand side simply by changing the
+/- sign on the display.
Grade Matching In Direct Grade Entry mode the movement of the leveling mechanism
moves at the same speed as the grade counters.
To match an existing slope, set up the laser over the known gradebreak
(base) of the slope, and align the cross axis (level only) of the laser to
the end of the slope with both control points parallel to the direction of
grade.
Adjust the Rod-Eye receiver on your grade rod for the elevation of the
laser at the gradebreak next to the laser.
Move the grade rod to a point on the slope that is too be matched. Then,
dial grade into the laser until the Rod-Eye indicates an on-grade reading.
The percent of grade in the display is now equal to the grade being
matched.

3.2 Identification of the Axes
1. X+ Axis – When positive grade is entered in the X-axis, grade will
increase in this direction.
2. Y Axis – Always level
3. Front of Rugby – See also axis labeling on the side of the laser and
inside the top windows.
3.3 Slope - Percent of Grade
Slope The change in elevation per unit of measure (foot, meter, etc.)
Percent of Grade The change in elevation per 100 units of measure (feet, meters, etc.)
Calculating Percent
of Grade from the
Slope
3.4 Alignment of the Axes
When the desired grade is correctly set in the display, it is necessary to
align the X and Y axes to the jobsite.
Ensure the circular level vial is positioned near the center of the circle for
maximum self-leveling capability.
Ensure the Rugby is properly positioned over a control point.
As shown, 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 sights are aligned with your second
control point.
Once aligned, work can begin.
Slope = 0.0059
Conversion = 0.0059 x 100
Percent of Grade = 0.590%

Rugby 320 SG 9Operation
)An optional sighting scope is also available.
)For very accurate alignment, refer to the steps for Precise Alignment of
the Axes.
3.5 Precise Alignment of the Axes
Under most conditions, the raised alignment marks on the top of the
Rugby are adequate for alignment of the axes. However, for more
precise alignment, use the following procedure.
Objective • To establish Point A on the Y-axis as a reference and take an eleva-
tion reading.
• To dial grade into the X-axis and then adjust the position of the laser
until the original elevation at Point A is again found.
Procedure 1. With 0.000% grade in both axes, set up the Rugby directly over a
grade stake and rough align the Y-axis to a second grade stake that
we will call 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 in the
X-axis, the Y-axis acts like a hinge or fulcrum.
4. With 5.000% in the X-axis, take a second reading at Point A.
Alignment • If the second reading is equal to the first reading, the X-axis is
aligned correctly.
• If the second reading is greater than the first reading, rotate the
Rugby clockwise (to the right) until the two readings are the same.
• If the second reading is less than the first reading, rotate the Rugby
counter-clockwise (to the left) until the two readings are the same.

Rugby 320 SG Setup10
4 Setup
4.1 General Setup
Location Make sure the location is clear of possible obstructions that may block
or reflect the laser beam.
Make the most efficient use of the Rugby’s operating radius. The Rugby
can be placed in the center of the working area or to one side.
Make sure the ground is stable. Ground vibration and extremely windy
conditions can affect the operation of the Rugby.
If working in very dusty conditions, place the Rugby up-wind. The dirt and
will then be blown away from the Rugby and reduce interference.
Recommended
Head Speeds
For surveying and manual machine control applications the typical head
speed is 10 rps (600 rpm).
For automatic machine control applications it is recommended to use the
highest head speed, 20 rps, to increase the frequency of updates.
When working at extended distances, decreasing the head speed
(increasing the pulse time on the receiver) or changing the band width
of the receiver to wide band can improve distance and performance.
Tripod Setup Attach the Rugby securely to a tripod or laser trailer, or mount on a
stable level surface.
Always check the tripod or trailer before beginning work.
Make sure all screws, bolts, and nuts are tight.
If your tripod has chains, they should be slightly loose to allow for
thermal expansion during the day.
On extremely windy days, secure the tripod. Placing a sandbag on each
leg can do this. (See also adjustment for setting the wind sensitivity of
the Rugby.)
If using a tripod with a quick disconnect adapter, point the control lever
into the wind. This places the locking mechanism also into the wind, and
will provide better stability.
4.2 Setup Options
The Rugby has several setup options that are easily accessed and
changed in the first setup screen.
From the main operating screen, Press STAR to access the
setup screen.

H.I. (Height of
Instrument)
The H.I. function is used to prevent elevation changes caused by move-
ment of the tripod.
When the H.I. Alert function is activated, the self-leveling accuracy
remains the same, but the self-leveling range of the Rugby is reduced.
Movement of the Rugby beyond its self-leveling range will cause an “alert
condition”. The Rugby will stop rotating and the following screen will
appear on the display:
Stop the “alert condition” by pressing the Star or Power button and reset
the function.
Check carefully the setup and elevation of the unit to determine what
has caused the alert condition. Adjust as required to the correct eleva-
tion.
The H.I. function can be turned on or off in the first setup screen.
When the H.I. function is turned on, the letters “HI” will appear in the
bottom, right part of the display.
The H.I. function becomes active 30 seconds after the unit has
completely leveled and the head starts rotating.
Automatic and
Manual Mode
The Rugby will always turn on in automatic mode and will continuously
self-level to maintain grade accuracy.
)In manual mode the self-leveling function is turned off.
The display screen will show the following:
The X-axis slope can be changed using the X and arrow buttons, but the
amount of change is not shown in the display.
The H.I. function can be made to turn on automatically
at power-up. This can be enabled in the second setup
screen.

Rugby 320 SG 13Setup
Manual Mode with
Grade
In Manual Mode with Grade, the display will alternately show the grade
entered for the X-axis and the crossed out level vial as shown here:
In this mode, grade can be entered into the X-axis. The Rugby will self-
level to the grade input in the unit, then will lock into manual mode at
this grade.
)Once locked in manual mode the self-leveling function is turned off.
If it is desired to change the manual grade shown, a new grade can be
entered (same as in automatic mode) and the Rugby will level to this new
grade, then lock in manual mode.
Wind Sensitivity The Wind Sensitivity setting allows the Rugby to operate in adverse envi-
ronmental and windy conditions, while still ensuring maximum accuracy.
Beam Masking Electronic Beam Masking allows the operator to turn off the laser beam
in specific quadrants to prevent interference with other operations on
the job.
Using the setup menu, the beam can be turned off in up to three
selected quadrants.
When a quadrant is turned off, the space will appear dark.
The sensitivity numbers can be set from 1 to 5. Select “1”
for calm conditions. Select “5” for very windy conditions.
Use the lowest setting for conditions present.
The quadrants selected can be either diagonals of
corners of the Rugby. This selection is made in the
second setup screen.
The settings for beam masking are normally not saved
when the Rugby is turned off. The Rugby can be made to
save the mask settings in the second setup screen.

Rugby 320 SG 15Checking Level Accuracy
5 Checking Level Accuracy
)It is the responsibility of the user to follow operating instructions, and to
periodically check the accuracy of the instrument and work as it
progresses.
)The Rugby is adjusted to the defined accuracy specification at the
factory. It is recommended to check your laser for accuracy upon receipt
and periodically thereafter to ensure accuracy is maintained. If your laser
requires adjustment, contact your nearest authorized service center or
adjust the laser using the following procedure.
)Do not enter this mode or attempt adjustment unless you plan to change
the accuracy. Accuracy adjustment should be performed only by a quali-
fied individual that understands basic adjustment principles.
5.1 Checking Level Accuracy
To check level accuracy of your Rugby, place the unit on a flat, level
surface or tripod approximately 100 feet (30 meters) from a wall.
Checking the X-Axis Align the X-axis so that it is square to the wall. Allow the unit to self-level
completely (approximately one minute after the unit begins to rotate),
and then, using your Rod-Eye receiver, mark the position of the beam
(Position 1).
Rotate the Rugby 180°, allow it to self-level and then mark the opposite
side of the X-axis (Position 2).
Mark the position half-way between the two marks. The X-axis is within
its accuracy specification if the two marks are within ± 1/16” (± 1.5 mm)
from center.

6.1 Batteries
The unique battery solution in the Rugby has two independent battery
compartments that will accept various combinations of NiMH packs or
individual D-cell batteries (2).
The battery status is displayed on power-up and as small icons on the
main operating screen.
Install the NiMH batteries (1) as shown on the label of the pack.
Install individual D-cell batteries (2) as shown on the battery door cover.
The charge jack (3) is located on the laser above the locking knob of the
battery door (4).
Charge time is approximately 4-5 hours.
The Rugby can also be run directly from a 12-volt source through the
charge jack.
Charging / First
Time Use
• The batteries must be charged prior to using it for the first time
because it is delivered with an energy content as low as possible.
• The permissible temperature range for charging is between +32°F to
+104°F (0°C to +40°C). For optimal charging we recommend charging
the batteries at a low ambient temperature of +32°F to +68°F (0°C
to +20°C) if possible.
• It is normal for the battery to become warm during charging. Using
the chargers recommended by Leica Geosystems, it is not possible to
charge the battery if the temperature is too high.
• For new batteries or batteries that have been stored for a long time
(> three months), it is effectual to make 3 - 5 charge/discharge cycle.
Operation/
Discharging
• The batteries can be operated from -4°F to +122°F (-20°C to +50°C).
• Low operating temperatures reduce the capacity that can be drawn;
very high operating temperatures reduce the service life of the battery.

Rugby 320 SG Accessories18
6.2 The Sighting Scope
A sighting scope (739870) is available as an optional accessory for
alignment of the axes and second day setups.
The scope is magnetically mounted to the top of the housing and once
aligned has a repeatable accuracy of approximately ± 0.2°.
Alignment of the
crosshairs
If using the scope for reference or second day setup, use the raised
sights on the top of the laser to align your Rugby to a second control
point.
The scope is roughly aligned at the factory. If a more precise alignment
is desired, first align the Rugby to a second control point using the proce-
dure for Precise Alignment of the Axes found in this manual.
