Frequently Asked Questions - AutoCrossLaser 3C Plus Laserliner

How do I turn on the AutoCrossLaser 3C Plus?

Turn the transport fastener (2) clockwise to release the pendulum lock. The device will self-level and the horizontal laser will light constantly. Use the H and V buttons to switch individual lasers on/off.

What should I do if the lasers blink continuously?

Blinking indicates the device is beyond its self-levelling range (±2.5°). Use the adjustable feet (6) to level the device or place it on a more level surface. The round vial (8) helps with approximate alignment.

How can I check the calibration of the laser level?

Place the device midway between two walls at least 5 m apart. Mark points A1 and A2, then move the device close to one wall and mark A3. The difference between A2 and A3 should be ≤ 2 mm per 10 m. If not, contact service.

Can I use the AutoCrossLaser 3C Plus with a laser receiver?

Yes, press the hand receiver mode button (10) to switch to pulsating mode. The laser lines become darker but can be detected by compatible RX laser receivers for long distances or bright light.

How do I replace the batteries?

Open the battery compartment (9) on the bottom. Insert 3 x 1.5V AA batteries according to the polarity symbols. Close the compartment. The low battery warning is indicated by a flashing bubble level (8).

What is the transport lock and how do I use it?

The transport fastener (2) locks the pendulum system. Always turn it counterclockwise to lock the pendulum before moving or storing the device to prevent damage. Switch off the device first.

How accurate is the AutoCrossLaser 3C Plus?

The device has a precision of ± 2 mm per 10 m. Self-levelling range is ±2.5°. Regular calibration checks ensure accuracy. The vertical line accuracy can be checked against a plumb bob with a deviation ≤ ±1.5 mm.

What are PowerBright and RX-READY technologies?

PowerBright uses high-performance diodes for super bright laser lines visible over long distances and in bright light. RX-READY makes the laser lines pulsate at high frequency for detection by laser receivers in unfavorable light conditions.

Can I use the AutoCrossLaser 3C Plus outdoors?

Yes, but visibility may be reduced in bright sunlight. Using the hand receiver mode with a laser receiver is recommended for outdoor use over long distances. The device operates in temperatures from 0°C to +50°C.

How do I clean and maintain the laser level?

Keep the laser windows clean using a soft, dry cloth. Do not use solvents. Store the device in a dry place with the pendulum locked. Check calibration before use, after transport, and after long storage.

Read the operating instructions and the enclosed brochure „Guarantee and additional notices“ completely. Follow the instructions they contain. Safely keep these documents for future reference.

Function / Application

Cross-line laser vertical and horizontal alignment

• The pivoted housing can be turned with a vernier adjustment mechanism to permit exact positioning of laser lines.
• Plumb laser at bottom to position the device
• Adjustable feet with removable rubber caps
  – Automatic levelling range 2.5°, accuracy 2 mm / 10 m
  AutoCross-Laser 3C / 4C / 7C:

- A simple, precise plumb function is afforded by the additional plumb laser at the bottom and the laser cross at the top.

- The vertical lines are aligned at right angles to one another.

General safety instructions

Laser radiation! Do not stare into the beam or observe it directly with optical instruments.

Class 2M laser < 5 mW · 635-650 nm EN 60825-1:2007-10

Caution: Do not look directly into the beam. Lasers must be kept out of reach of children. Never intentionally aim the device at people. This is a quality laser measuring device and is 100% factory adjusted within the stated tolerance. For reasons of product liability, we must also draw your attention to the following: Regularly check the calibration before use, after transport and after extended periods of storage. We also wish to point out that absolute calibration is only possible in a specialist workshop. Calibration by yourself is only approximate and the accuracy of the calibration will depend on the care with which you proceed.

Special product features

LEVEL Automatic alignment of the device with a magnetically dampened pendulum system. The device is brought into initial position and aligns itself autonomously.

Transport LOCK: The device is protected with a pendelum lock during transport.

PowerBright LASER Devices with PowerBright technology have special high- performance diodes to produce super bright laser lines These remain visible over longer distances, in bright ambient light and on dark surfaces.

RX-READY technology enables line lasers to be used even in unfavourable light conditions. The laser lines pulsate at a high frequency and this can be picked up by special laser receivers over long distances.

For transport, the device must always be switched off with the transport securing device (2) so as to protect device from damage.

2Horizontal and vertical levelling

Turn the transport fastener (2) clockwise and release the pendulum lock. The lasers are now automatically aligned by the pendulum system and the horizontal laser lights constantly. The lasers can be switched on and off individually with the H and V buttons. It is now ready for levelling in the horizontal or vertical plane.

!

If the device is too far off the horizontal (more than 2.5°), the lasers will blink. Align the device using the adjustable feet (6) or place on a more level surface. The round vial (8) is provided as an aid to alignment.

B Positioning laser lines

The top section of the laser unit can be turned on the plinth to align the lasers approximately. Precise positioning can then be done with the Vernier adjustment (3). The adjustable feet (6) allow the device to be positioned on sloping surfaces.

4 Hand receiver mode

Optional: Working with the laser receiver RX

Use an RX laser receiver (optional) to carry out levelling at great distances or when the laser lines are no longer visible.

To work with a laser receiver, switch the line laser into hand receiver mode with the Hand receiver mode button (10). The laser lines will now pulsate with high frequency, making the laser lines darker. The laser receiver RX can detect these pulsating laser lines.

!

Follow the operating instructions of the corresponding laser receiver.

Preparing the calibration check:

It is possible for you to check the calibration of the laser. To do this, position the device midway between 2 walls, which must be at least 5 metres apart. Do this by turning the unit on, thus releasing the transport restraint (cross laser on). Please use a tripod.

1. Mark point A1 on the wall.
2. Turn the device through 180^ and mark point A2. You now have a horizontal reference between points A1 and A2.

Performing the calibration check:

1. Position the device as near as possible to the wall at the height of point A1.
2. Turn the device through 180^ and mark point A3. The difference between points A2 and A3 is the tolerance.

When A2 and A3 are more than 2 mm / 10 m apart, an adjustment is necessary. Contact your authorised dealer or else the UMAREX-LASERLINER Service Department.

Checking the vertical line:

Position the device about 5 m from a wall. Fix a plumb bob with a line of 2.5 m length on the wall, making sure that the bob can swing freely. Switch on the device and align the vertical laser to the plumb line. The precision is within the specified tolerance if the deviation between the laser line and the plumb line is not greater than ± 1.5 mm.

Checking the horizontal line:

Position the device about 5 m from a wall and switch on the cross laser. Mark point B on the wall. Turn the laser cross approx. 2.5 m to the right and mark point C. Check whether the horizontal line from point C is level with point B to within ± 2 mm. Repeat the process by turning the laser to the left.

Regularly check the adjustment before use, after transport and after extended periods of storage.
