Handling of laser beams

• Do not look directly into the beam, not even from great distances.
• Never direct the measuring beam towards people, other living creatures or reflecting surfaces.
• Conventional laser glasses do not protect against the dangers of laser beams. They only serve for improved recognition of the laser beam.

4. Loosen the adjusting knob (9).
5. Swivel the device to the desired position.
6. Retighten the adjustment knob (9).
7. To unfasten the clamping jaws, loosen the  universal clamp (6) until the can be removed from the carrier without difficulty.

Using the tripod (not included)

1.  Place the device with the 1/4″ tripod connection (4) on the thread of the tripod or a conventional camera tripod.
2. Roughly align the tripod before switching on the device.

OPERATION

Only the centre of the laser line must be used for marking. The width of the laser line changes depending on the distance.
It’s recommended to carry out an accuracy check before first use and periodic checks during future use, especially for precise layouts. Also when the laser may have been dropped.
** Danger of injury due to defective components! The product must only be put into operation if no defects are found.
Ensure that any defective parts are replaced before the product is used again.
WARNING! Risk of injury due to laser beam!** Never direct the laser beam towards people, other living creatures or reflecting surfaces.

Charging the device (Fig. C)
**** The device must be charged before first use.

1. Plug the USB type-C plug (10) into the USB type-C connector (13) on the device.
2. Plug the USB type-A plug (12) into an power adapter (not included) or device (e.g. computerpowerbank) with suitable female USB connector. Please note that the device should be able to deliver constant 5V 2A power.

3. The Battery LED indicator (5) will lighten up and show the charging status.
   LED Charger status

   Red| Battery charging in progress
   Green| Charging finished, battery fully charged

4. After the battery is fully charged remove the USB type-C plug (10) from the USB type-C connector (13).

It is also possible if the battery is empty to power the device with the charger or with a power bank. Follow the steps as above.
When the device is not being used over a longer period of time it is best to store the battery in charged condition.

Check the device:

• Make sure all parts are fitted on the machine firmly.
• Check whether there are any visible defects: broken parts, cracks, etc.
• Check the accuracy when it is the first time you are using the laser or when the laser has not been checked for accuracy in a while.
• Also check the accuracy when the laser may have been dropped.:
• Make sure all parts are fitted on the machine firmly.
• Check whether there are any visible defects: broken parts, cracks, etc.
• Check the accuracy when it is the first time you are using the laser or when the laser has not been checked for accuracy in a while.
• Also check the accuracy when the laser may have been dropped.

Self- levelling mode (Fig. A, D1)
The lasers are aligned automatically by the pendulum so that the vertical and horizontal lines are displayed level on the wall.

1. Place the laser on a flat surface or fit it to the universal clamp (7) or tripod (not included) and fasten it as described above.
2. Slide the lock switch (2) to the right. Press the ON / OFF button (1) on the device to power on. If the laser flashes, the permissible inclination range of 5 degrees is exceeded. Position the device horizontally until the laser stops flashing.
3. To switch off, slide the lock switch (2) to the left and press the ON / OFF button (1). The laser switches off and the pendulum will be locked.

**** Slide the lock switch (2) to the left when transporting it. This locks the pendulum unit, as it can otherwise be damaged.

Manual mode (Fig. A, D2)
The laser can be aligned manually to the angle you require, to enable for example a diagonal line to be displayed.

1. Place the laser on a flat surface or fit it to the universal clamp (7) or tripod (not included) and fasten it as described above.
2. Check if the lock switch (2) is set to the left. If not, slide the lock switch (2) to the left.
3. Press the ON / OFF button (1) to switch the laser on.
4. Now you can tilt the laser to the angle you require, so that the lines are displayed diagonally on the wall as shown in Fig. D2.
5. To switch off , press the ON / OFF button (1).

MAINTENANCE

Accuracy check
**** Only the centre of the laser line must be used for marking. The width of the laser line changes depending on the distance.

Quick horizontal line check (Fig. A, E1)

1.  Set the device at approximately 5 meters from the wall.

2. Slide the lock switch (2) to the right. Press the ON / OFF button (1) on the device to power on.
   If the laser flashes, the permissible inclination range of 5 degrees is exceeded. Position the device horizontally until the laser stops flashing.

3. After it self-levels, make a horizontal mark on the wall as shown in figure E1. Label this as point A.
   4. Turn the laser 2.5 m to the right.

4. Turn the laser on, and after it self-levels, make a horizontal mark on the wall. Label this as point B as shown in figure E1. When points A and B are more than 2.5mm apart from a vertical perspective, a calibration check is necessary.

Quick vertical line check (Fig. A, E2)

1. Set the device at approximately 5 meters from the wall.

2. Hang a 2.5 meter rope on the wall with a weighon the end of the rope as shown in figure E2.
   The rope must be able to swing freely.

3. Slide the lock switch (2) to the right. Press the ON / OFF button (1) on the device to power on. Position the vertical line next to the wire. If the laser flashes, the permissible inclination range of 5 degrees is exceeded. Position the device horizontally until the laser stops flashing. After it self-levels, the difference must not exceed ± 2.5 mm. When it’s more than 2.5mm apart, a calibration check is necessary.

Calibration check (Fig. A, F)
The accuracy of the horizontal beam can be checked by following these steps:

1. Set the device on a tripod, centered in a room with walls ideally 5 meter away.

2. Slide the lock switch (2) to the right. Press the ON / OFF button (1) on the device to power on.
   If the laser flashes, the permissible inclination range of 5 degrees is exceeded. Position the device horizontally until the laser stops flashing.

3. After it self-levels, make a horizontal mark on the wall anywhere along the horizontal line to indicate the height of the beam. Label this as point A as shown in Fig. F1.

4. Turn the device 180°, and after it self-levels, mark point B as shown in Fig. F2.

5. Turn the device 180°. Position the device as near as possible to the wall at the height of point A as shown in Fig. F3.

6. Turn the device 180°, and after it self-levels, mark point C. This mark should either be directly above, below or on top of point B as shown in Fig. F4. The difference between points B and C is the tolerance. When B and C are more than 0.5 mm/ m apart, an adjustment is necessary. Contact your authorized dealer or else the Vonroc Service Department.
