Operation; Examples Of Applications - Hilti PMP 45 Manual De Instrucciones

7 Operation

7.1 Operation
7.1.1 Switching the laser beams on
Press the on/off button once.
7.1.2 Switching the tool / laser beams off
Press the on/off button until the laser beam is no longer
visible and the LED goes out.
NOTE
The tool switches itself off automatically after approx. 15
min.
7.1.3 Deactivating the automatic power-off feature
Press and hold the on/off button for approx. 4 sec. until
the laser beam blinks three times as confirmation.
NOTE
The tool will be switched off when the on/off button is
pressed or when the batteries are exhausted.

7.2 Examples of applications

7.2.1 Setting out drywall track for a partition
wall 3
7.2.2 Marking out the position of light fittings 4
7.3 Checking
7.3.1 Checking the plumb point 5
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.
7.3.1.1 Calculation of accuracy
10
R = x
RH [m]
30
R = x
RH [ft]
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).
7.3.2 Checking leveling of the forward beam 6
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 position of the laser point on the wall (A)
with a cross.
3. Pivot the tool through 180° and mark the position of
the laser point 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 position of the laser point on the wall (B)
with a cross.
6. Pivot the tool through 180° and mark the position of
the laser point 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 dif-
ferent 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.
7.3.3 Checking perpendicularity (horizontal) 7 8 9
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 vertical laser line lies exactly in the center of
the laser point.
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.
