STABILA LAX 400 Self Levelling Multiline Laser Instruction Manual

STABILA LAX 400 Self Levelling Multiline Laser

Operating Instructions

The STABILA-LAX 400 is an easy-to-operate self-levelling multi-line laser, designed for use on building sites. The laser unit is self-levelling within the range of ± 4°. The fine adjustment allows precise 90° angles to be projected.
The laser lines are pulsed which makes it possible to work over greater distances using a special STABILA line receiver. For more information refer to the operating instructions for the line receiver.
If you still have questions after reading through the operating instructions, you can obtain advice by telephone:

• Only permit qualified persons to operate the unit!
• Observe the safety precautions!
• Attach the warning label in your language to the laser unit. The relevant adhesive labels are enclosed. The positioning of the labels is described in the operating instructions.

Warning:
Your eyes are normally protected by their lid closure reflex and / or a natural instinct to turn away if you accidentally look into the laser beam of class 2 laser units very briefly. If a laser beam hits your eye, consciously close your eyes and move your head out of the path of the beam. Do not look into the direct or reflected beam.
The STABILA laser goggles available with laser units are not protective goggles, rather allow the laser light to be seen more easily.

•  Do not aim the laser beam directly at people!
• Avoid dazzling other people!
•  Keep out of the reach of children!
• It can result in dangerous exposure to radiation if operating and adjustment equipment, or methods other than those described in these operating instructions, are used.
• Tampering (modifications) with the laser unit is not permitted.
• The unit may malfunction if it is dropped or suffers serious vibrations!
• Always check before you start work that the unit is functioning correctly and accurately, especially if it has been exposed to heavy vibrations.
• Do not use in explosive or corrosive environments!
• Do not dispose of the batteries and unit with domestic waste!
•  Keep this user manual in a safe place and hand it over when passing the unit to another person.

Dispose of used batteries at suitable collection points – not with household waste.
Remove the batteries if you do not intend to use the unit for some time!

Always use the centre of the laser line when marking and aligning!

Commissioning with levelling function

Turn the laser casing to the working position. Use the sliding switch (9) to switch on the laser unit. Horizontal and vertical laser lines and the plumb- line laser dot appear. The LED lights up green. The LAX 400 is in self- levelling mode and levels itself automatically.

Selecting the laser functions

Once the unit has been switched on using the sliding switch (9), use button (11) to switch between the various laser functions.

Levelling functions:

• 2 x vertical laser lines at a 90° angle
• 1 x 360° horizontal laser line
• 1 x plumb-line function

Plumb-line laser function:

The plumb-line dot will be clearly visible after the laser casing has been pushed up and the feet spread apart (7). This can be used to position the LAX 400 precisely.

 Commissioning without levelling function

Only use the button (11) to switch on the LAX 400 in Marking function mode. The horizontal and vertical laser lines, plumb-line dot and LED flash quickly. The LAX 400 is not in self-levelling mode and can only be used in this mode for marking and alignment!

Marking functions:

• 2 x vertical laser lines at a 90° angle
• 1 x 360° laser line
• 1 x dot laser

Additional functions

Function: Height adjustment

Use the clamping lever (4) to adjust the height of the laser casing.

Function: Fine adjustment

Use the fine adjustment (2) to rotate the laser casing to an exceptionally high degree of precision, which allows the vertical lines to be precisely aligned.

Checking the accuracy

The LAX 400 multi-line laser is designed for use on building sites and is perfectly adjusted before leaving our premises. Regularly check the calibration of the accuracy, as is the case with all precision instruments. Always check the unit before starting work, especially if it has been exposed to heavy vibrations.

• Vertical check
• Horizontal check
• Angle check

Vertical check

Checking the 2 vertical laser lines

1.  Create a reference line, e.g. with a plumb line.
2.  Set up and align the LAX 400 at distance Y in front of this reference line.
3.  Compare the laser line with the reference line.
4.  Do not allow the laser line to deviate from the reference line by more than 1 mm ( 11/256” ) over a distance of 2 m (7’) !
5.  Perform this check for both vertical laser lines.

Checking the plumb-line function

1.  Align the LAX 400 precisely with one floor marking using the plumb dot.
2. The projected laser line cross appears on the ceiling.
3. Turn the LAX 400 around 180° and align it once again with the floor marking using the plumb-line dot.
4. The projected laser line cross appears on the ceiling.
5.  The difference measured between the markings is twice the actual discrepancy. With a ceiling height of 5 m ( 16’5” ), the difference should be no more than 3 mm ( 1/8” ).

Horizontal check

Checking the level of the horizontal laser line
2 parallel walls at a distance S of at least 5 m (16’5”) apart are needed to carry out the horizontal check.

1. Position the LAX 400 as close as possible to wall A on a horizontal surface.
2. Use an exit window for a vertical laser line to align the LAX 400 with wall A.
3.  Switch on the laser unit (sliding switch 9 )
4.  Once automatic levelling has ended, mark the cross projected onto wall A. Point 1.
5.  Turn the LAX 400 around 180° and align with wall B using the same vertical laser line exit window. Do not adjust the height.
6.  Once automatic levelling has ended, mark the cross projected onto wall B. Point 2.
7.  Now reposition the laser unit so that it is directly in front of wall B. Align the LAX 400 with wall B using the same exit window for a vertical laser line.
8.  Move the laser line cross by turning and adjusting the height until it precisely coincides with point 2.
9.  Turn the LAX 400 round 180° and align with wall A using the same vertical laser line exit window. Do not adjust the height.
10. Move the laser line cross by turning the casing until it precisely coincides with the marking line of point 1.
11.  Once automatic levelling has ended, mark the cross projected onto wall A. Point 3.
12.  Measure the vertical distance between points 1 and 3. Perform this check with both vertical laser lines!

Distance S to the wall Maximum permissible distance:

• 5 m                                      3.0 mm
• 10 m                                   6.0 mm
• 15 m                                   9.0 mm
• 16’5”                                  1/8”
• 32’10”                                  1/4”
• 49’3”                                 3/8”

Angle check

Checking the 90° angle

1.  Mark point A on the floor at a distance of 10 m (32’10”) in a sufficiently large corner of the room.

2.  Align the LAX 400 with point A using the plumb-line dot.

3.  Align the LAX 400 with the one wall using a laser line.

4.  Precisely mark point B on the floor at the halfway point.

5.  Precisely mark point C on the wall or floor.

6.  Shift the LAX 400 and align with point B using the plumb-line dot.

7. Align the LAX 400 with point C again using the laser line.

8.  Precisely mark point D on the other wall or on the floor using the 90° laser line.
   Note: The distance from A to B, B to C and B to D should be the same to guarantee accuracy.

9.  Turn the LAX 400 through 90° and align laser line 1 with point D.

10.  Mark position E on the perpendicular 2nd\ laser line as close as possible to point A.

11.  Measure the distance between points A – E.
