SAFETY

Follow these guidelines before operating any jobsite equipment:

• Read and follow all safety precautions.

• Do not operate equipment unless you have completed proper training and read the operator’s manual.

• Use equipment only as directed.

• Wear personal protective gear.

• Check that equipment is clean and in good condition.

Contact your Subsite Electronics dealer if you have any question about operation, maintenance, or equipment use.

CLASSIFICATIONS

CLASSIFICATIONS

Watch for the three safety alert levels: DANGER, WARNING and

CAUTION. Learn what each level means.

indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

Watch for two other words: NOTICE and IMPORTANT.

NOTICE can keep you from doing something that might damage the machine or someone’s property. It can also alert you against unsafe practices.

IMPORTANT can help you do a better job or make your job easier in some way.

OPERATION

The 750 tracker has four operation modes: tracker control, walkover beacon tracking, remote guidance, and line locating.

Potential radio frequency (RF) hazard. Operating this device within 4 in (10 cm) of your body may cause RF exposure levels to exceed FCC RF exposure limits and should be avoided.

IMPORTANT: Large metal objects, rebar, power lines and any other kinds of interference can adversely affect depth estimates.

BEACON TRACKING MODES

Set-up

You must calibrate tracker before beginning a beacon tracking job.

After calibration, tracker can estimate depths from approximately

9 in (0.2 m) to 100 ft (30.5 m) depending on beacon used. Keep the following in mind when calibrating system:

• Beacon and tracker should not be moved or rotated until calibration is complete.

• Only depth estimation is affected by calibration. Roll, pitch, left/right deviation, temperature, and battery status are not affected.

• Large metal objects, rebar, power lines, and any other kinds of interference will adversely affect calibration.

22

750 Tracker — OPERATION

BEACON TRACKING MODES

Calibration Procedure

1.

Install beacon into toolhead and place on ground exactly 10 ft (3 m) away from tracker. Make sure no metal objects including drilling unit and drill pipe are within 20 ft

(6 m) of tracker and toolhead.

2.

Position tracker parallel to center of toolhead.

3.

Turn tracker on and press and hold depth and up arrow keys until calibration mode is entered. Release keys.

4.

Verify calibration by moving tracker 15 ft (4.5 m) away from toolhead. Check depth. If reading is not 15 ft (4.5 m), recalibrate tracker.

BEACON TRACKING MODES

Tracker Control Mode

Overview

Incorrect procedures could result in death, injury, or property damage. Learn to use equipment correctly.

This mode allows 750 Tracker operator to disable hydraulic power to drilling unit thrust and rotation within 16 seconds. This

mode will not stop thrust and rotation immediately.

When tracker and display communications cease, green tracker control light on drilling unit will come on and thrust and rotation will be disabled.

Troubleshooting tip: If thrust and rotation do not work, check whether tracker control light on drilling unit is on. If it is, communication has probably stopped between tracker and display or tracker is set to incorrect code. If communication cannot be restored, install tracker control key on drilling unit.

Tracker control light will go off and thrust and rotation will function.

IMPORTANT:

•

Tracker operator cannot stop thrust and rotation from tracker with tracker control key installed in drilling unit and turned to disable position.

• Tracker control mode is available on units with “TC” at the end of their serial numbers.

4.

Drill and track bore until drill head enters target pit or exits ground.

5.

Turn off tracker. After 8-16 seconds, tracker control light on drilling unit will come on and hydraulic power to thrust and rotation will be disabled.

6.

Change downhole tools.

7.

If you are tracking backreamer’s path, turn on tracker and enable code transmission. After 8-16 seconds, tracker control light on drilling unit will go off and thrust and rotation will function.

If you are not tracking backreamer’s path, install tracker control key on drilling unit. Tracker control light on drilling unit will go off and thrust and rotation will function.

Walkover Tracking Mode

Location

1.

Turn on tracker. Make sure you can see fore/aft arrows in center of display. If you see left/right arrows, press fore/aft/ left/right key.

2.

Walk bore path with bottom of tracker parallel to beacon. Do not hold tracker at right angle to beacon.

IMPORTANT: A common problem when locating a beacon is secondary or ghost signals. A typical beacon signal pattern shows a main signal and two weaker secondary signals.

Track beacon at main signal. Familiarity with beacon signal pattern will lessen the effect of secondary signals. Also, the beacon tracking arrows will disappear when tracker is over secondary signal.

3.When both fore/aft arrows are on, sweep tracker from side to side and use signal strength display to find lateral location of beacon (point

A).

4.Step back until ghost is located (no arrows in center of clock face and low signal strength) and then move slightly forward until only one arrow is lit

(point B).

5.

Press fore/aft/left/right button to switch to left/right arrows and sweep tracker back and forth until both left/right arrows are on.

6.

Switch back to fore/aft arrows and move forward until both fore/aft arrows and target is lit.

7.

Take depth estimate and mark spot.

BEACON TRACKING MODES

Remote Guidance Mode

Information is transmitted directly to display at drilling unit when tracker is in remote guidance mode. Approximate distance from tracker to beacon (not the estimated depth of the drill head) is shown every 5 seconds.

28

BEACON TRACKING MODES

Distance will not be correct within one and a half times the toolhead depth. For example, if you are drilling at 4 ft (1.2 m), you will be able to drill within 6 ft (1.8 m) of tracker.

To operate in remote guidance mode, place unit in stand while it is turned off. Press and hold mode button while pressing on/off button.

Tracker and drill head can be up to 60 ft (18.3 m) apart when in remote guidance mode. IMPORTANT: Do not drill past tracker.

Displayed Information

Beacons send a variety of information to tracker. All Subsite

Electronics beacons send pitch, roll, temperature and battery information.

Roll

Beacon roll information is useful in determining the direction that the drilling tool will tend to travel when pushed without rotation.

The following chart shows typical tool face roll indications for directional drilling.

Depth

To estimate beacon depth, press depth button. Estimated depth to beacon will be displayed. To change depth units, press depth and mode buttons.

All tracking and locating systems are subject to interference. To quickly check for interference, raise tracker 1 ft (0.3 m) and make second depth estimate. If the difference between the two estimates is not 1 ft (0.3 m), there is interference.

Pitch

Tracker shows pitch (% grade) when used with beacons that provide this information (see specific beacon literature).

Pitch shows beacon grade in percentages from down arrow 99%

(45 degrees down) to up arrow 99% (45 degrees up). Tracker displays this information to the left of roll display.

Grade beacons will send pitch in 0.1% increments from 1-45% and in 1% increments from 45-90%.
