1. Introduction
This manual provides essential information for the safe and effective operation, maintenance, and troubleshooting of your STANLEY FATMAX FMHT1-77441 Rotary Laser Level. Please read this manual thoroughly before using the product and retain it for future reference.
The STANLEY FATMAX FMHT1-77441 is a self-leveling rotary laser level with a green beam, designed for alignment, horizontal and vertical leveling, squaring, and inclined plane applications. Its robust FATMAX design ensures durability for intensive professional use.
2. Safety Information
WARNING: This product emits a Class 2 laser beam. Direct eye exposure to the laser beam may cause eye injury. Do not stare into the laser beam. Do not intentionally direct the laser beam at others.
- Always wear appropriate laser safety glasses when operating the device, especially in bright conditions where the beam may be difficult to see.
- Ensure the laser is set up on a stable surface to prevent accidental movement.
- Do not attempt to modify or disassemble the laser level. This may result in hazardous laser radiation exposure and will void the warranty.
- Keep the device out of reach of children.
- Operate the laser level only in well-ventilated areas.
- Avoid using the laser level near highly reflective surfaces that could redirect the beam.

4. Product Features
The FMHT1-77441 Rotary Laser Level is engineered with advanced features for precision and durability:
- FATMAX Design: Enhanced robustness and ergonomics for intensive professional use.
- Self-Leveling: Automatic leveling for quick and accurate setup in horizontal and vertical applications.
- Green Laser Diode: Class 2 green laser beam for improved visibility in various lighting conditions.
- Dual Plumb Beams: Projects both up (green) and down (red) plumb points for precise vertical alignment.
- Manual Slope Adjustment: Allows for manual adjustment of slopes on both X and YZ axes, up to 10%.
- Protective Glass: Durable glass protects the laser head from damage.
- High Accuracy: Provides an accuracy of 1.5mm at 30 meters.
- Extended Range: Operates with a range of up to 300 meters with a detector.
- Rubberized Protection: Rubber grip and protective elements on the base enhance solidity and impact resistance.
- ADS Alarm: An Automatic Displacement System (ADS) alarm signals any accidental movement or displacement of the level, ensuring measurement integrity.
- Tilt Function: Enables the laser to be set at an angle for specific applications.
- 5/8" Thread: Compatible with standard tripods and mounting accessories.
5. Setup
5.1. Battery Installation and Charging
- Locate the battery compartment on the laser level.
- Insert the NiMH rechargeable batteries, ensuring correct polarity.
- Close the battery compartment securely.
- Connect the battery charger to the laser level and a power outlet. Allow sufficient time for a full charge before first use.
5.2. Mounting the Laser Level
- Tripod Mounting: The laser level features a 5/8" thread on its base. Securely attach it to a compatible tripod. Ensure the tripod is stable and level.
- Wall Mounting: For vertical applications, the laser level can be mounted to a wall bracket (sold separately) using the integrated mounting points.

6. Operating Instructions
6.1. Powering On/Off
- To power on, press the power button. The laser will begin its self-leveling sequence.
- To power off, press and hold the power button until the laser beam extinguishes.
6.2. Self-Leveling Operation
Once powered on, the laser level will automatically self-level. If the device is outside its self-leveling range, an alarm may sound, and the laser beam may flash. Adjust the device's position until it self-levels.
6.3. Horizontal Leveling
- Place the laser level on a stable surface or tripod.
- Power on the device. It will self-level to project a horizontal plane.
- Use the laser detector to locate the beam at desired points across the work area.

6.4. Vertical Leveling and Squaring
- Mount the laser level vertically using a wall bracket or a tripod configured for vertical operation.
- Power on the device. It will self-level to project a vertical plane.
- The up (green) and down (red) plumb points can be used for precise vertical alignment and squaring tasks.
Figure 6.2: Vertical leveling application.
6.5. Manual Slope Adjustment (Tilt Function)
For inclined plane applications, the FMHT1-77441 allows manual slope adjustment up to 10% on both X and YZ axes.
- Engage the manual mode (refer to the device's control panel or remote for specific button). This will disable self-leveling.
- Use the directional buttons on the device or remote control to adjust the laser plane to the desired angle.
- Confirm the angle with an external measuring tool if high precision is required for the slope.

6.6. Using the Laser Target Plate
The laser target plate enhances the visibility of the laser beam, especially over longer distances or in bright conditions. Place the target plate at the desired measurement point to easily identify the laser line.

7. Maintenance
- Cleaning: Regularly clean the laser level with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the laser output window is clean for optimal performance.
- Storage: Store the device in its carrying case in a dry, cool place when not in use. Remove batteries if storing for extended periods to prevent leakage.
- Calibration: While the device is self-calibrating, periodic professional calibration is recommended to ensure continued accuracy, especially after significant impacts or prolonged use.
- Battery Care: Follow the manufacturer's instructions for charging and discharging NiMH batteries to maximize their lifespan.
