Description

Use of the product as directed

The PMC 46 is a self-leveling combilaser which allows a single person to level, plumb, align and transfer right angles quickly and accurately.
The tool projects two lines (horizontal and vertical) and five points (above, below, right, left and line intersection).
The lines and line intersection point have a range of approx. 10m.
All other points have a range of approx. 30m.
Range depends on the brightness of ambient light.
The tool is designed mainly for indoor use and is no substitute for a rotating laser.
When used for outdoor applications, care must be taken to ensure that the general conditions are similar to those encountered indoors.
Possible applications are:

• Marking the position of partition walls (at right angles and in the vertical plane).
• Aligning components to be installed or sections of a structure in three axes.
• Checking and transferring right angles.
• Transferring measuring marks from the floor to the ceiling.
• Observe the information printed in the operating instructions concerning operation, care and maintenance.
• The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used not as directed.

Features

The PMC 46 levels itself automatically within a range of approx. 5°.
Self-leveling takes only approx. 3 seconds.
The combilaser gives an “Out of self-leveling range” warning when the self- leveling range is exceeded (the laser beams blink).
The PMC 46 is characterized by its ease of operation and use, its rugged plastic casing and ease of transport due to its compact dimensions and light weight.
The tool can be used together with the PMA 31 laser receiver.
In the normal operating mode, the tool switches itself off after 15 minutes.
Sustained operating mode can be activated by pressing and holding the on- switch for four seconds.

Checking

Checking the plumb point 9

1. Make a mark on the floor (a cross) in a high room (e.g. in a stairwell or hallway with a height of 5–10 m).

2. Place the tool on a smooth, level (horizontal) surface.

3. Switch the tool on.

4. Position the tool with the lower beam on the center of the cross.

5. Mark the position of the vertical beam on the ceiling.
   Attach a piece of paper to the ceiling before making the mark.

6. Pivot the tool through 90°.
   NOTE The lower plumb beam must remain on the center of the cross.

7. Mark the position of the vertical beam on the ceiling.

8. Repeat the procedure after pivoting the tool through 180° and 270°.
   NOTE The resulting 4 marks form a circle in which the intersection of the diagonals d1 (1 – 3) and d2 (2 – 4) marks the exact center of the plumb point.

9. Calculate the accuracy as described in section 7.3.1.1.

Calculation of accuracy

The result (R) provided by this formula (RH = room height) refers to the tool’s accuracy “in mm at 10 m” (formula (1)).
This result (R) should be within the specification for the tool (3 mm at 10 m).

Checking leveling of the forward beam 10

1. Place the tool on a smooth, level surface approx. 20 cm from the wall (A) with the laser beam directed toward the wall (A).

2. Mark the point of intersection of the laser lines on the wall (A) with a cross.

3. Pivot the tool through 180° and mark the point of intersection of the laser lines on the opposite wall (B) with a cross.

4. Place the tool on an even, level surface approx. 20 cm from the wall (B) with the laser beam directed toward the wall (B).

5. Mark the point of intersection of the laser lines on the wall (B) with a cross.

6. Pivot the tool through 180° and mark the point of intersection of the laser lines on the opposite wall (A) with a cross.

7. Measure the distances d1 between 1 and 4 and d2 between 2 and 3.

8. Mark the mid points of d1 and d2.
   If the reference points 1 and 3 are located on different sides of the mid point, then subtract d2 from d1.
   If the reference points 1 and 3 are located on the same side of the mid point, then add d1 and d2 together.

9. Divide the result by twice the length of the room (room length x 2).
   The maximum permissible error is 3 mm at 10 m.

Checking leveling of the lateral beams 10
Repeat the procedure and calculate the accuracy of each of the two perpendicular beams as described at 7.3.2.

Checking perpendicularity (horizontal) 11 12 13

1. Position the tool with the lower plumb beam on the center of a reference cross in the middle of a room at a distance of approx. 5 meters from the walls so that the center of the vertical laser line lies exactly on the vertical line of the first target plate (a).

2. Attach a second target plate or sheet of paper (b) to the wall at the half-way position (as shown in the illustration).
   Mark the mid point (d1) of the right-hand perpendicular beam.

3. Pivot the tool clockwise through exactly 90° (as seen from above).
   The lower plumb beam must remain in the center of the reference cross and the center of the left-hand perpendicular beam must then lie exactly on the vertical line of target plate (a).

4. Mark the center point (d2) of the right-hand perpendicular laser beam on target plate (c).

5. Mark the mid point (d3) of the point of intersection of the laser lines on target plate (b) or the sheet of paper (from step 7).
   NOTE The horizontal distance between d1 and d3 must be no greater than 3 mm at a working distance of 5 m.

6. Pivot the tool clockwise through exactly 180° (as seen from above).
   The lower plumb beam must remain in the center of the reference cross and the center of the right-hand perpendicular beam must then lie exactly on the vertical line of target plate (a).

7. Then mark the center point (d2) of the left-hand perpendicular laser beam on target plate (c).
   NOTE The horizontal distance between d2 and d4 must be no greater than 3 mm at a working distance of 5 m.
   NOTE If d3 is to the right of d1, the sum of the horizontal distances d1-d3 and d2-d4 must be no greater than 3 mm at a working distance of 5m.
   NOTE If d3 is to the left of d1, the difference between the horizontal distances d1-d3 and d2-d4 must be no greater than 3 mm at a working distance of 5m.

Checking the horizontal lines for curvature 14 15

1. Place the tool at the edge of a room with a length of at least 10 m.
   NOTE The floor surface must be smooth and level.

2. Switch on all laser beams.

3. Set up a target plate at a distance of at least 10 m from the tool, so that the point of intersection of the laser lines lies in the center of the target plate (d0) and the vertical line on the target plate runs exactly through the middle of the vertical laser line.

4. Mark the mid point of the lower plumb beam on the floor (reference cross).

5. Pivot the tool clockwise through 45° (as seen from above). The lower plumb beam must remain on the center of the reference cross.

6. Then mark the point (d1) on the target plate where the horizontal laser line strikes the vertical line on the target plate.

7. Pivot the tool counterclockwise through 90°.
   The lower plumb beam must remain on the center of the reference cross.

8. Then mark the point (d2) on the target plate where the horizontal laser line strikes the vertical line on the target plate.

9. Measure the following vertical distances: d0-d1, d0- d2 and d1-d2.
   NOTE The greatest measured vertical distance must be no more than 5 mm at a working distance of 10 m.

Checking the vertical lines 16

1. Position the tool at a height of 2 meters.

2. Switch the tool on.

3. Position the first target plate T1 (vertical) at a distance of 2.5 meters from the tool at the same height (2 meters), so that the vertical laser beam strikes the plate. Mark this position.

4. Then place the second target plate T2 at a position 2 meters below the first target plate, so that the vertical laser beam strikes the plate. Mark this position.

5. Mark position 2 at the opposite side of the test setup (mirror image) on the laser line on the floor at a distance of 5 meters from the tool.

6. Now place the tool on the floor on the mark for position 2 which you have just made.
   Direct the laser beam toward the target plates T1 and T2 so that it strikes the plates close to their center lines.

7. Read the distances D1 and D2 from each target plate (distance of the laser line from the center of the target plate) and calculate the difference (D = D1 – D2).
   NOTE Take care to ensure that the target plates are parallel to each other and that they are in the same vertical plane. (Horizontal alignment may result in measurement error).
   If the difference D is greater than 3 mm, the tool must be returned to a Hilti repair center for adjustment.
