The Hilti PM 24 is a self-levelling laser tool which allows a single person to do plumbing, setting out 90° angle, horizontal levelling and aligning tasks quickly and precisely. It projects four coincident laser beams (beams with the same point of origin). All beams have the same operating range of 30 m (100 ft). However, the maximum recommended distance of the reference beam (plumb down) is 1 m (3,3 ft), due to its lower accuracy.

Features

– High accuracy of horizontal beams and plumb up beam

(3 mm @ 10 m or 1/8 inch @ 30 ft)

– Additional reference beam downwards

(2 mm @ 1 m or 1/12 inch @ 3 ft) – Self-levelling within ± 5° in all directions – Fast self-levelling time: ~ 3 seconds – Out-of-level warning when the self-levelling range is exceeded

(the laser beams blink) – Robust, impact-resistant plastic housing – Small size and light weight - handy to use and transport – Automatic cut-out: the tool switches off automatically after 15

minutes. Selection of sustained operating mode is also possible. – Easy to operate

Laser warnings for the USA based on FDA 21 CFR:

2. Safety information

The PM 24 plumb laser corresponds to laser class 2, based on the standards IEC 825-1 / EN 60825, and class II based on FDA 21 CFR. The eyelid closure reflex protects the eyes should anyone happen to look briefly into the laser beam. However, this eyelid closure reflex can be impaired by medicines, alcohol or drugs. These devices may be used without further protective measures. Nevertheless, as with the sun, care should be taken to avoid looking directly into the

light source. Do not direct the laser beam at people.

Horizontal Levelling and aligning with the PM 24

The PM 24 can do horizontal levelling and aligning in two ways:

1. Directly over the surface ➪ Place the PM 24 over the reference surface. Level the other surface using the target plate.

2. Mounted with an accessory ➪ Mount the PM 24 with an appropriate accessory at the desired height. Rotate the PM 24 and mark the points or perform the installation directly.

When performing levelling and aligning applications with the PM 24 mounted on the PA 271 stand, first check the reference by holding the target plate directly in front of the tool. This reference may or may not be on the center of the target plate and will apply to all further levelling points.

3. Operation and use

Using the accessories

a) Frame clamp When using the Frame clamp (e.g. at a door frame), the magnetic bracket can be slid onto the stationary jaw of the clamp by way of the rail at the rear. The protective cover should be fitted over the magnet.

b) Magnetic bracket The protective cover should be removed from the magnets before using the magnetic bracket.

c) Wall bracket The wall bracket is used for mounting the PM 24 on a non-magnetic surface. Screws or nails can be used to fasten the wall bracket to surfaces of this kind. The PM 24 can be set up on the wall bracket with the magnetic holder (protective cover removed).

d) Tripod Head Tripod Head with 1/4 “ thread.

3. Operation and use

The tool should be checked on regular intervals at room temperatures (25˚C or 77˚F) to ensure compliance with the technical specifications.

Plumb Up Beam

1. Mark a point (a cross) on the floor of a high room (e.g. a stairwell, (5-10m or 15-30 ft)).

2. Put the tool on a level floor and switch it on.

3. Bring the reference beam point on top of the center of the cross.

4. Mark the corresponding up beam on the ceiling (easier if paper is taped there)

5. Turn the tool 90° so that the reference beam stays on the same point and mark again on the ceiling.

6. Repeat the same at 180° and at 270°.

7. The 4 resulting points on the ceiling define a circle of which the crossing point of the diagonals d

(1– 3) and d2(2– 4) mark the

exact plumb point.

8. Calculate accuracy:

The result of the formula refers to the accurcy in “mm @ 10 m” (equation (1)) or the accuracy in “inch @ 30 ft (equation (2)). The result shall be within the PM 24 specification: 3 mm @ 10 m [1/8 inch @ 30 ft].

4. Accuracy check

Level and Square Beam (horizontality)

1. Place the PM 24 on the floor near wall (A). Mark the center

of the laser spot (1) with a cross. Turn the tool through 180 °. Mark the center of the laser spot (2) with a cross.

2. Place the tool near wall (B) and direct the beam towards

wall (B). Mark the center of the laser spot (3) with a cross. Pivot the tool trough 180 °. Mark the center of the laser spot (4) with a cross.

3. Measure the distance d1 and d2. Mark the middle point in

d1 and d2. If the reference points 1 and 3 are on different sides of the middle point (see the example), subtract d2 from d1. If they are on the same side of the middle point, add d1 to d2. Divide the result by twice the length of the room. For PM 24: max. error = 3mm / 10m or 1/4” at 60feet. Example: d1 = 6mm, d2 = 4mm, room length = 10m, points 1 and 3 are on different sides of the real level line.
