Rugby 300 SG 1.1.0en
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 information
specific to your jobsite requirements.
The Rugby Grade lasers are rugged,
accurate and fully electronic with an
operating range up to 2,500 feet (770
meters) diameter.
The Rugby 300 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 Precise
Alignment of the Axes.

Operation
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.

Rugby 300 SG 1.1.0en
Identification of the Axes
1X+ Axis – When positive grade is
entered in the X-axis, grade will
increase in this direction.
2Y Axis – Always level
3Front of Rugby – See also axis
labeling on the side of the laser and
inside the top windows.
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:
Slope = 0.0059
Conversion = 0.0059 x 100
Percent of Grade = 0.590%
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.
)An optional sighting scope is
also available.
)For very accurate alignment,
refer to the steps for Precise Alignment
of the Axes.

9Rugby 300 SG 1.1.0en
Operation
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
elevation 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.

10 Setup
Rugby 300 SG 1.1.0en
Setup
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.

Setup
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
environmental and windy conditions,
while still ensuring maximum
accuracy.

Checking Level Accuracy
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 qualified individual that
understands basic adjustment
principles.
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” (± 1.6 mm) from
center.
Checking the Y-Axis
Align the Y-axis by rotating the Rugby
90° so that the Y-axis is now square to
the wall. Allow the unit to self-level
completely, then check the Y-axis in
