1.
Set up the Rugby and the slope adapter on a tripod.
2.
Set up the tripod at the base of the slope with the Rugby and the
slope adaptor pointing in the direction of the desired slope.
3.
Set the slope adapter to the zero position on the bracket and on
the knob. Roughly level the top of the tripod using the circular level
on the slope adapter.
4.
Turn on the Rugby and Combo.
5.
Attach the Combo to a rod.
6.
At the base of the slope, adjust the height of the Combo on the rod
until the on-grade (centre-line) position is indicated on the Combo
by:
the centre bar,
•
a solid audio tone.
•
7.
Enter maximum grade value. It is best practice to use the Rugby
lasers grading to its limits before using the slope adapter.
8.
Press the OK/Grade button to confirm the grade entry.
9.
Set manual levelling. Manual levelling stops the laser attempting to
re-level once the slope adapter is being used.
Use the slope adapter to extend the grade capabilities of the laser.
The Combo can now be used to control the grade of the slope.
☞
Batter Boards
The Rugby and the Combo create a vertical plane of laser light that acts as a
virtual string line for batter board setups.
