Warnings and Safety Precautions

It is very important that Directional drilling operators note the operating procedures and safety
precautions before operating the Radiodetection DrillTrack G2 system.

- Priority must be given to local and national safety requirements all times.

All other safety procedures should be followed.

- All underground utilities MUST be located before starting the drilling operation.

Contact your local Radiodetection dealer for pipe and cable locating equipment.

- Serious injury and death can result if underground drilling equipment accidentally

hits an underground utility.

- Operators must wear protective safety clothing such as insulated boots, insulated
gloves, high visibility safety vests, safety glasses and hard hats.

The DrillTrack G2 system is not explosion-proof and is not approved for use in areas
where hazardous gases may be present.
The DrillTrack G2 system should never be used near flammable or explosive substances.

Prior to the start of each drilling, the following actions must be taken:

- An orientation working practice should be selected which is done in the
DrillTrack G2 Receiver Setup Menu.

Confirm that the DrillTrack G2 system is operating properly and check for an
accurate location of the drillhead and accurate depth readings, tilt angle and roll
position with the DataSonde inside the drillhead.

During drilling, the depth readings and locate position will not be accurate unless:

- A consistent orientation working practice will be maintained. (changing from facing
the Drilling machine to working with one’s back to the Drilling machine or visa versa)
could result in both a mis-locate position/depth error.
This effect is more likely to happen after approximately 10% Grade (5°) of Tilt angle.
Note, at any time the user may go back into the “Setup Menu” and change the
orientation method. This will not effect the Receiver’s calibration.

- The DrillTrack G2 Receiver has been calibrated correctly.

IV

Warnings and Safety Precautions

Interference can cause inaccuracies in depth readings, loss of tilt angle and/or roll position and
inaccurate location and heading of the rill head.

- Sources of interference could be power lines, cable TV, traffic signal loops, telecom
lines, pipelines, metal structures, invisible dog fences, radio frequencies,
transmission towers and cathodic protection systems.

- Due to the nature of the equipment it may be susceptible to electromagnetic fields
emitted by other apparatus. This may cause incorrect data to be displayed.

Care must be taken when using Lithium batteries to avoid drilling conditions which would result in
the DataSonde exceeding the battery manufacturers recommended maximum operating
temperature. In the event of exceeding this temperature the battery may vent toxic fumes into the
sealed battery compartment and may explode if the temperature rises further.

Ensure that the battery manufacturers specified maximum operating temperature exceeds
100°C.

Follow all safety and handling precautions specified and supplied by the battery manufacturer.

If the warranty temperature indicator of the DataSonde, located next to the slot of the anti-roll pin,
has turned black then the DataSonde temperature has exceeded 104° C. Do not remove the
battery end cap as toxic fumes or harmful chemicals may be released.

Ni-Cad batteries should be disposed of in accordance with your Company’s work practice, and/or
the relevant law or guidelines in your country.

Carefully review this user guide. If you have any questions regarding the operation of the
equipment or if you have difficulty on the job, please contact your local Radiodetection dealer for
help.

DrillTrack G2 System Overview

Features of DrillTrack G2 Receiver and DataView.

The DrillTrack G2 Receiver has been developed with the needs of the operator as the main priority.

Providing essential information automatically makes the equipment very easy to use and allows the
operator to work with confidence.

Once drilling has started the operation is fully automatic and the large LCD shows the operator
information about the drillhead.

The DrillTrack G2 Receiver LCD provides automatic walkover positioning of the drillhead.
Four arrows automatically direct the operator left/right and forward/backward.

When all four arrows are displayed the depth automatically appears on the screen and can be stored in
the integral Borelog.

The display also provides the operator with a Drill Heading (compass), Tilt angle (Inclination), Roll
Position and in the Manual Mode a Signal Strength reading (if selected in the user Setup).

Feature highlights include:

- Integral Borelogger

- Automatic tracking arrows that indicate Go... Left/Right/Forward/Backward.

- Drill head direction compass indicator.

- Interference rejection technology.

- Filtered rejection of standard line locator frequencies.

- No mis-locates due to ‘ghost signals’.

- No confusion caused by +/- locates.

- Down hole frequency change to overcome localised interference.

- Tilt angle compensated locate position and depth measurements.

- Automatic Depth readout.

- Metric or Imperial readout selection.

- Continuous display of Tilt angle and Roll.

- Tilt angle in % of Grade or degrees.

- D isplay Backlight.

- Comfortable working height to minimize fatigue.

DrillTrack G2 System Overview

The DrillTrack G2 DataView has been developed with the needs of the Drilling machine operator as the
main priority.

With its magnetic base the portable DrillTrack G2 DataView provides essential information that allows
the Drilling machine operator to work with confidence.

Once drilling has started the operation is fully automatic and the large LCD shows the Drilling machine
operator with all the relevant data transmitted from the DataSonde to the DrillTrack G2 Receiver and
which is then relayed to the DrillTrack G2 DataView in real time.

The information includes, Tilt angle (Inclination), Roll (clock), Depth, Remote Left/Right steering and
Alarm Conditions.

Feature highlights include:

- Fully automatic with no operational buttons or controls.

- Depth readout upon request.

- Automatic selection of Metric or Imperial readout.

- Continuous display of Tilt angle and Roll in real time.

- Tilt angle in % of Grade or degrees.

- Continuous display of DataSonde Temperature and DataSonde Battery status.

- Remote Left/Right steering.

- Display Backlight.

DataSonde

The Radiodetection DataSondes.

The DataSonde is installed in the drillhead/DataSonde housing.
To ensure optimum DataSonde performance and protection, the DataSonde should be securely fitted in
the drillhead/DataSonde housing. DataSondes may need minor modifications to ensure a secure fit.
O-rings or electrical tape are an acceptable means.

All Radiodetection DataSondes are constructed in three main sections.

Electronics

Antenna

Battery Compartment

Battery compartment
Batteries are inserted in the back end of the DataSonde with the positive end first. Always use ALKALINE
batteries.

Antenna
The antenna is positioned in the middle section of the DataSonde. The slots in the drillhead/DataSonde
housing should be positioned over the antenna section of the DataSonde to allow the electro magnetic
field from the DataSonde to be generated without any restriction.
Wrong positioning or length of the slots will effect the signal range and battery life of the DataSonde.

Electronics
The sensors for measuring the Roll (clock), the Tilt angle (Inclination), the DataSonde Temperature and
the Battery Status are located in the electronics section of the DataSonde.

The slot in the front end of the DataSonde fits the anti-roll pin in the drillhead/DataSonde housing
to stop the DataSonde from rotating inside the drillhead DataSonde housing, when drilling.
