A710 Multipurpose Laser Owner’s Manual
GENERAL INFORMATION Thank you for buying the Agatec A710 laser! Although the A710 is simple to use, we recommend that you read this manual before operating the laser. Description The A710 is a visible universal laser that can be used for leveling, vertical alignment, squaring, and single and dual slope grade control. It has a digital grade display and is ideal for machine control and other dual grade applications. It’s totally waterproof and has a beam designed for pipelaying.

HOW TO USE THE A710 Setup Horizontal The laser can be used on a 5/8-11 tripod, on a wall mount, or directly on a solid, stable surface. Vertical The laser can be placed directly on a solid, stable surface. If you are using it in a pipe or other confined space, you can detach the handle with a 3mm Allen wrench so it has a narrower profile. Place the laser on the side with the two adjustable feet (9). Rough level the laser by using the feet to center the bubble in the vertical vial (7).
Choice of transmission There is two-way communication between the laser and the remote control. If the remote is within range and properly communicating with the laser, a symbol (ψ or ↑ ) will appear on the display (28). The remote signal can be either radio frequency (RF/ψ) or infrared (IR/↑ ). RF is the default when the laser is turned on. All laser functions will work in RF or IR mode. Radio frequency Turn on the remote control / keypad with the On / Off key (13).
H.I. Alert H.I. (height of instrument) Alert stops the laser automatically if the laser is disturbed or moved, preventing inaccurate readings. It will function only when selected. To activate this safeguard feature, press the “lock” key (11). A lock is also shown on the display (22). If the lock is closed, it’s in the H.I. Alert mode. If the lock is open, the H.I. Alert option has not been selected. ╭╮ ▀ ╭ ▀ If the laser is disturbed while in H.I.
Scanning Scanning mode allows you to see the beam easier at a distance. To switch from rotation to scan, press the scanning key (17). A scanning symbol appears on the display (21). The scanning beam has three lengths, shown as 1, 2, or 3 on the display. Use the ½ up or ¾ down arrows on the multi key (10) to change scan lengths. Hold down the » or ¼ arrows to move the scan left or right. To stop scanning, press the rotation key (18).
Calculating percent of grade Percent of grade is the change in elevation from Point A to Point B over a 100 ft. distance. To calculate %, divide the difference in elevation between A and B by the distance and multiply by 100. Example 1 – Positive grade: Close point A and far point B are 300 ft. apart Rod reading at A is 6 ft.; at B, 2 ft. Difference in elevation: 4 ft. Divide 4 by 300 =.01333 x 100 = 1.333. Percent of grade is + 1.333% (B is 4 ft. higher than A, so it’s a positive grade.
Checking the grade It is recommended that you check if the grade you selected is correct and that the laser is positioned correctly in relation to the grade. Use a detector to pick up the beam. A +1% grade will have a 1 ft. rise in elevation over 100 ft. (10 cm rise over 10 meters of run). A -1% grade will have a fall of 1ft. over 100 ft. Setting vertical grade – Z axis Follow vertical setup on page 3. If the laser will be submerged, remove the remote control (which is not waterproof).
Batteries Laser battery The A710 has a NiMh rechargeable battery that should be charged for 15 hours before first use. A battery symbol on the display (24) indicates the battery charge. Important: If the battery charge is weak or the battery is discharged, you cannot select a grade setting. Charging the battery 1) Remove the cap on the jack located on the side of the laser. Insert the charger plug. 2) Plug the charger into an electrical outlet (110 volts or 220 volts, depending on charger and country).
Checking and adjusting the A710 THIS CHAPTER IS VERY IMPORTANT: Here are a few simple instructions to check your A710 for calibration. Remember that the laser is a precision instrument and that it is important that you keep it calibrated and in proper condition. The accuracy of your work is completely your responsibility and you should regularly check your instrument especially prior to important jobs. How to check and calibrate The laser has 3 axes: X and Y (horizontal) and z (vertical).
Checking X axis 1) Place the laser on a flat surface or tripod 50 or 100 ft. (30 m) away from a wall. Position so that -X is facing the wall (this is the side of the laser with the On/Off key). 2) Turn on the laser and remote control. There must be no grade set in the laser. Both X and Y grade displays must be at 0%. 3) Mark the location of the center of the beam. If it’s too bright to see the beam, use a detector, or put in scan mode. 4) Rotate the laser 180 degrees so that +X faces the wall.
4) If you have not moved the laser, use the X marks made in Steps 3 & 5 of “Checking X axis.” Mark the spot that’s halfway between the two marks. 5) Use the left » and right ¼ arrows on the multi key (10) to move the beam to the halfway mark. If +X is facing the wall, the right arrow moves the beam up and the left arrow, down. CAUTION: Do NOT use the up or down arrows. This will change the settings of the Y axis.
1) To put the laser in calibration mode, simultaneously press the backlight key (12) and X / Y key (15). A blinking symbol H over a point appears on the display (27) to indicate that you are calibrating a horizontal axis. 2) Press the rotation key (18) and choose a rotation speed with the multi key (10). Note that the H symbol (27) has stopped blinking. 3) Press the X/Y key (15) to re-activate the calibration mode. The H symbol will blink again.
3) Turn on the laser and remote control. There must be no grade set in the laser. The Z grade display must be at 0%. 4) Use either scan or rotation mode. Using the scanning beam is easier, but if you cannot see the beam, work in rotation mode with a detector. To change from rotation to scan mode: press scan key (17) and choose the widest scan length – 3 – with the up ½ arrow of the multi key (10). 5) Move the scan to the wall over the plumb line, using the left » and right ¼ arrows.
5) Use the up ½ and down ¾ arrows on the multi key (10) to move the beam until it’s perfectly vertical and parallel to the plumb line. Move the laser slightly so that the beam is over the plumb line for the final check. 6) After completing the Z calibration, simultaneously press the backlight key (12) and X / Y key (15) to exit calibration mode. This will also turn the laser off. Cone error checking 1) Set up the laser about 2 feet away from a wall (a) or pole and 100 feet from another wall (b) or pole.
Care and Handling CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. 1) The A710 is a precision instrument that must be handled with care. Avoid shock and vibrations. 2) After use, it’s recommend that you wipe the laser dry and store in a dry place. Do not store the laser in its case if the laser or the case are wet.
