2. How to use your SKR301 laser

An overview of laser and keypad functions can be found in the inside front cover.

The laser does a self-test when turned on. The beam blinks while the laser is self-leveling. After it has leveled, the head will start to rotate.

2.1 Auto/Man key (20)

• Auto: Automatic leveling

Default mode when laser is switched on
- Man: Manual use

The SKR301 laser is always in the automatic self-leveling mode (auto) when turned on. Once the instrument has self-leveled, the laser head will start rotating.

You can choose to have constant rotation by using the manual mode. This way, the beam will rotate even if the instrument is not leveled (necessary when working on inclined planes).

For safety, a red light will blink above the Auto/Manual button to advise the user that the laser is in manual mode.

2.2 Tilt key (22)

Tilt : H.I.-Alert mode. Will work only when selected. The Tilt function is also known as the H.I. (height of instrument) Alert. This feature stops the laser automatically if the laser is jarred or moved, preventing inaccurate readings. Use this feature only in automatic mode, not in manual.

Push the Tilt key (22) after turning the instrument on. The H.I. Alert feature is available 30 seconds after the instrument has self-leveled. The red light above the Tilt key will blink when operating in this mode. If the laser is disturbed, the head will stop rotating and the red light will be on continuously. Turn the laser off, wait 5 seconds, and turn it on again (check that the beam is at its original reference).

2.3 Horizontal setup

1. The SKR301 laser can be used directly on the ground, on a wall mount or on a standard tripod (5/8 - 11).
2. Press the On/Off key (24) to switch the laser on. It will start its automatic leveling.
3. To select the Manual mode, press key (20).
4. To select the H.I.-Alert mode, press key (22). This feature is available 30 seconds after the laser has leveled itself.
5. If you wish to move the laser beam to a specific point, briefly press key (14) or (15).
6. To adjust the rotation speed, press key (14) or (15) continuously according to the direction you wish. To stop the rotation, press once on the opposite key.
7. To turn the laser off, press key (24).

2.4 Vertical setup

No accessories are needed for this position. The SKR301 can be used directly on the ground. However, it can be used on a mount for a better setup.

1. Flip up the retractable foot (7). Place the instrument in vertical position, resting on this foot. Use the adjustable feet (8) to rough level the laser.
2. Turn the instrument on. Once the instrument is leveled, the head will start rotating.

2.5 Squaring

1. Put the laser on the ground and repeat steps 1 and 2 for vertical use.

2. Stop the head rotation by pressing key (14) or (15).

3. To position the rotating vertical plane perpendicular to a reference line:

4. Align the arrow (5) located below the beam aperture with the index (6) located above the retractable foot (there is also an index mark on the foot).

5. Move the laser so that the beam is over the reference point on the ground, keeping the arrow and index aligned.
6. Align the beam projecting from the top of the head to your second reference point with key (16) or (17) on the laser or with the detector or remote control. (This beam is 90^ , or square, to the other vertical plane beam).
7. Start rotating the head using keys (14) or (15) to change speed or use the chalk line.

It is important to check while you're using the laser that it has not been moved and that your setting is still accurate.

2.6 Rotation speed

Your laser is equipped with a visible laser diode. It may be necessary to adjust the rotation speed according to the ambient light conditions using keys (14) and (15).

The laser beam is more visible in slow motion. It is possible to stop the rotation and point the beam manually to view the beam over long distances.

2.7 Using the chalk line

Ideal for viewing at short distances. To use the laser line feature, hold the head and rotate the top cover (12) so that the beam comes out of the laser line aperture (4). This will give a precise and stable laser line for working directly on your reference plane. You can move the line by rotating the head manually or by using the remote control.

The LDR180 detector will not work with the chalk line feature.

2.8 Using the scanning mode

Allows you to see the beam easier when the laser is further away. To use the scanning feature, turn the laser on. The laser should be in 'point' mode.

If it is in chalk line, hold the head and rotate the top cover (12) so that the beam comes out of the beam aperture (3). To put laser on scan mode, use keypad, detector, or remote.

1. To scan, simultaneously press (14) and (17). The beam will blink until it has self-leveled, and then will start scanning.
2. Use (14) or (15) to aim the scan.
3. Use the bottom two keys to adjust the scanning length. Use (17) to increase and (18) to decrease (3^ to 34^) .
4. To turn the scanning off, simultaneously press (14) and (17) again. The square shot cannot be moved left or right when scanning; laser must be in point or chalk line mode.

2.9 Manual slope

1. After turning the laser on and allowing it to self-level, press the Auto/Man key (20). The LED next to it (19) will blink, indicating you are in manual mode and you can set slope in the X axis. The head will start rotating.
2. Press (17) to set a positive slope in X and press (16) to set a negative slope.
3. To switch to the Y axis, press the Tilt key (22). Both LEDs (19) and (21) will blink, indicating that you are in manual mode and that you can set slope in Y axis.
4. Press (17) to set a positive slope in Y and (16) to set a negative slope.

3.0 Power

3.0.1 Installing alkaline batteries

1. To install alkaline batteries in your SKR301 laser, unscrew the battery cap located at the bottom of the instrument.
2. Remove the battery pack.
3. Insert two alkaline batteries (D or LR20) in the pack, matching the polarity (^ + ^ or - - ^ ) as indicated at the bottom of the pack.
4. Put the battery back into its place and tighten the screw. Your A 410 is ready for use.

To replace batteries

1. When battery power is low, the laser head will stop rotating, and the low battery light (23) will come on.
2. Replace both batteries at the same time.

3.0.2 Using rechargeable batteries

First-time use

If your SKR301 is equipped with rechargeable battery, you must recharge it for 15 hours before first use.

1. Insert the recharger jack plug into the jack located on the battery pack (10).
2. Plug the charger into an electrical outlet (110 volts or 220 volts, depending on charger and country).
3. Charge for 15 hours.

Always recycle batteries

Do not discard batteries into garbage can or the like

Later recharges

The SKR301 can be charged while working. If electricity is available on the job site, simply plug in the charger and keep on working. You can also remove the battery pack to charge it, and replace with the alkaline battery compartment to keep on working.

For optimum life of the battery, it is recommended to only charge the battery after it has been fully discharged.

To ensure battery life, do not charge over 20 hours. The battery and the charger can be damaged if damp. Always store and charge your instrument in a dry and covered place.

3. Checking and adjusting your SKR301

THIS CHAPTER IS VERY IMPORTANT: Here are a few simple instructions to check your SKR301 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. Before any checking on calibration ensure laser is in point mode when rotation stopped. Directions follow for checking each axis for calibration. If the laser needs to be calibrated, follow the instructions or take it to a service centre.

3.1 Horizontal checking and calibration (X and Y axis)

3.1.1 Horizontal checking

Y axis

Z axis

1. Place the laser on a flat surface 50 or 100 ft. (30m) from a wall. Position it so that the X 1 is facing the wall.

2. Turn the laser on. After it's level, stop the rotation so that the beam is a point.

3. Mark the location of the beam.

4. Rotate the laser 180^ . After 90 seconds, mark the location of the beam near the first mark.

5. Both measurements must be at the same place. At 100 ft., the marks should be no more than 18 apart. At 50 ft., the marks should be no more than 116 apart. (At 30 meters, no more than 6 mm apart). This is +/- 0.010% leveling accuracy.

6. If the marks are close enough, X axis is within calibration. The second axis (Y) must then be checked (see Step 7). If the marks are not close enough, the x axis needs to be re-calibrated (see instructions below).

7. To check the y axis, turn the laser 90^ from Step 4 so that Y 1 is facing the wall. Repeat the same steps: mark the Y beam, rotate 180^ , and mark again. If the marks are more than 1/8'' apart at 100 ft., Y axis should be re-calibrated.

3.1.2 Horizontal calibration

The laser must be calibrated to bring the beam to the centre of the two marks (Steps 3-4 in 3.1.1). The calibration is easily done using the laser keypad, remote control, or detector.

X axis calibration

1. Turn the laser off before switching to calibration mode. Simultaneously press two laser keys, On/Off and auto/man.
2. After a few seconds, release On/Off key.
3. The X LED indicator (23) will blink, then the y LED (21). Release the auto/man key.
4. The X LED (23) will blink rapidly, indicating the laser is ready to

be calibrated in the X axis. If you have not moved the laser, use the X marks made in Steps 3 and 4 of 3.1.1 (Horizontal Checking).

1. Mark the spot that's halfway between the two marks.
2. With X 2 facing the marks, bring the laser beam up or down to the centre mark by using (16) or (17) on the laser keypad or (2) or (3) on the detector or remote.
3. Next, check Y axis against centre mark. Tu m the laser 90^ so that Y 2 faces the wall. If the beam is not on the centre mark, calibrate Y. If Y is OK, see «Saving calibration» below.

Y axis calibration

1. To change to Y axis calibration, press (15) on the laser or (4) on detector or remote.
   The Y LED will blink rapidly, indicating that the laser is ready to be calibrated in the axis.
2. If you have not moved the laser, use the centre mark from above. Bring the laser beam up or down to that centre spot by using (16) or (17) on the laser keypad or (2) or (3) on the detector ro remote.

Saving the calibration

The laser is now calibrated in the X and Y axis. Press (14) on keypad or (5) on detector or remote to save the calibration data. If you don't wish to save the calibration, press the On/Off key (24) on the laser.

3.2 Vertical checking and calibration (Z axis)

3.2.1 Vertical checking

1. Place laser in vertical mode, on a flat surface about 10 ft. away from a plumb line (plumb bob hanging on a string, at least 8 ft. high). If you need to calibrate, beam will be easier to see in a darkened room.
2. Use the adjustable feet to rough level the laser.
3. Turn the laser on. Stop the rotation so that the beam is a point.
4. Hold the laser head and move the beam up and down the entire length of the plumb line by hand. If the beam is slanted, and not vertical like the plumb line, the z axis needs calibration.

3.2.2 Vertical calibration

1. Turn the laser off before switching to calibration mode. Simultaneously press On/Off and Auto/Man.

2. After a few seconds, release On/Off key.

3. The X LED indicator (23) will blink, then the Y LED (21). Release the Auto/Man key.
4. The Z LED (19) will blink rapidly, indicating laser is ready to be calibrated in Z axis.
5. Move the beam until it's vertical and parallel to the plumb line using (16) or (17) on the laser or (2) or (3) on the detector or remote. Move the laser slightly so that the beam is over the plumb line for the final check.

Saving the calibration

The laser is now calibrated in Z axis. Press (14) on laser or (5) on detector or remote to save the calibration data. If you don't wish to save the calibration, press the On/Off Key on the laser.
