The Hilti PM 2-LG is a self-leveling line laser designed for professional indoor leveling and alignment tasks. It projects two green lines (horizontal and vertical) and a line intersection point. The device is intended for use by trained, authorized personnel.
Product Overview
The device features a battery compartment, charge state indicator, receiver mode button, line mode button, laser exit window, mounting thread, and a selector switch for ON/OFF and pendulum lock/unlock.
Operation
- Batteries: Insert 4x AA batteries, ensuring correct polarity. Always replace all batteries at the same time.
- Switching On: Set the selector switch to the ON/unlocked position to activate all laser lines and points.
- Line Modes: Press the line mode button repeatedly to cycle through operating modes: all lines, horizontal line, vertical line.
- Inclined Line Function: Set the selector switch to the ON/locked position. The pendulum is locked, and the laser is not leveled.
- Receiver Mode: Press the receiver mode button to activate/deactivate. The laser beam flashes five times to confirm activation.
Checking Accuracy
Regularly check the accuracy of the laser, especially before important measurements or after the device has been subjected to mechanical stress (e.g., a fall).
- Leveling Check: Follow the procedure on page 16/27 to check the leveling of the laser beam between two walls.
- Horizontal Line Accuracy: Follow the procedure on page 16/28 to check the horizontal line accuracy.
- Vertical Line Accuracy: Follow the procedure on page 17/28 to check the vertical line accuracy using a doorway.
Care and Maintenance
Carefully remove stubborn dirt. Blow dust off the laser exit window; do not touch it with fingers. Clean the housing with a slightly damp cloth. Do not use silicone-based cleaning agents.
Troubleshooting
If the device does not switch on, check the battery level, polarity, and ensure the battery compartment is closed. If automatic leveling fails, ensure the device is on a flat, horizontal surface and the pendulum is unlocked.
