2 Description

2.1 Use of the product as directed
The PM 4-M is a self-leveling multi-line laser which allows a single person to transfer right angles, level horizontally and
carry out alignment work, and plumb accurately. The tool has three lines (one horizontal and two vertical), a reference
point at the bottom as well as four points of line intersection (front, top, left and right) with a range of approx. 10 m.
The range is dependent on the brightness of ambient light.
The tool is designed for mainly 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).
Checking and transferring right angles.
Aligning components to be installed or sections of a structure in three axes.
Transferring points marked on the floor to the ceiling.
The laser lines can be switched on both separately (vertical or horizontal line only) and together. When used with
inclination angle, the pendulum for automatic leveling is blocked.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Modification of the tool is not permissible.
To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
The tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used
not as directed.
2.2 Features
The PM 4-M levels itself automatically within a range of approx. 4°. If this is not sufficient, the tool can be leveled using
the adjustable feet and circular bubble level.
Self-leveling takes only approx. 3 seconds.
The multi-line laser gives an "Out of self-leveling range" warning when the self-leveling range is exceeded (the laser
beams blink).
The PM 4-M is easy to set up and operate and features a rugged plastic housing.
The tool can be used together with the PMA 31 laser receiver.
In the normal operating mode, the tool switches itself off after 1 hour. Sustained operating mode can be activated by
pressing and holding the on/off button for four seconds.
