- Green Laser Diode: Utilizes a 510-530 Nm Class 2 green laser for enhanced visibility.
- Wide Cross Line Projection: Projects a 150° wide cross line, offering extensive surface coverage.
- Self-Leveling System: Automatically levels within a 4° range in approximately 5 seconds.
- Pendulum Lock: Secures the pendulum during transport to prevent damage and allows for manual mode operation for angled lines.
- Magnetic Base: Features a magnetic base for direct attachment to metal structures.
- Receiver Mode: A dedicated button activates receiver mode, extending the working range up to 50 meters with an optional laser receiver.
- Durable Construction: Rubber-coated housing provides IP54 protection against dust and splashing water.
- Mounting Options: Equipped with 1/4" and 5/8" tripod threads for versatile mounting.

5. Setup
5.1 Battery Installation
- Locate the battery compartment cover on the back or bottom of the laser level.
- Open the cover by sliding or unlatching it.
- Insert 4 AA alkaline batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
5.2 Mounting the Laser Level
The FMHT77586-1 offers several mounting options:
- Flat Surface: Place the laser level directly on a stable, flat surface.
- Tripod Mounting: Attach the laser level to a tripod using the 1/4" or 5/8" thread on the bottom of the unit.
- Magnetic Mounting: Use the included L-bracket to attach the laser level to metal surfaces. The L-bracket has strong magnets for secure attachment.

6. Operating Instructions
6.1 Powering On and Self-Leveling Mode
- Unlock the pendulum by sliding the lock switch to the unlocked position.
- Press the power button (usually marked with a power symbol) to turn on the laser level.
- The laser level will automatically begin self-leveling. This typically takes about 5 seconds.
- Once leveled, the laser lines will emit a steady green light. If the device is outside its 4° self-leveling range, the laser lines may flash or an indicator light may illuminate, signaling that the device needs to be repositioned.
6.2 Switching Laser Modes
Press the mode button (often marked with a laser symbol or 'M') to cycle through different laser line configurations:
- Horizontal Line Only
- Vertical Line Only
- Cross Line (Horizontal and Vertical)

6.3 Manual Mode (Locked Pendulum)
To project angled lines, keep the pendulum locked. When the pendulum is locked, the self-leveling function is deactivated, and the laser lines can be projected at any angle. The laser lines may flash to indicate that it is in manual mode and not self-leveling.
6.4 Receiver Mode
For outdoor use or in bright conditions, activate receiver mode by pressing the dedicated receiver button (often marked with a signal icon). This increases the pulse rate of the laser, allowing it to be detected by an optional laser receiver for extended range (up to 50m). An indicator light will typically confirm receiver mode is active.

6.5 Powering Off
To turn off the laser level, press the power button again. Always engage the pendulum lock before storing or transporting the device to protect the internal mechanism.
7. Maintenance
- Cleaning: Wipe the laser level with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the laser apertures are clean for optimal beam clarity.
- Storage: Store the device in its carrying pouch in a dry, cool place, away from direct sunlight. Always engage the pendulum lock before storage.
- Battery Care: Remove batteries if the device will not be used for an extended period to prevent corrosion from battery leakage.
- Calibration Check: Periodically check the calibration of your laser level. Refer to the full product manual or STANLEY FATMAX support for detailed calibration procedures if needed.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are dim or not visible. | Low batteries; dirty laser aperture; too much ambient light. | Replace batteries; clean laser aperture; use in lower light conditions or activate receiver mode with an optional receiver. |
| Laser lines are flashing. | Device is outside its self-leveling range; pendulum is locked (manual mode). | Reposition the device on a more level surface; unlock the pendulum for self-leveling mode. |
| Device does not power on. | Batteries are dead or incorrectly installed; pendulum lock is engaged. | Replace batteries and check polarity; ensure pendulum is unlocked (for self-leveling mode). |
| Inaccurate measurements. | Device is not level; calibration issue; unstable surface. | Ensure the device is within its self-leveling range; check calibration; place on a stable surface. |
