The Stanley FMHT33865S FATMAX tape measure incorporates several features designed to enhance its functionality and durability:

- 16" and 19.2" Stud Center Markings: Clearly indicated on the blade to simplify framing tasks.

3. Setup
The Stanley FATMAX tape measure is ready for use directly out of its packaging. No assembly or battery installation is required.
3.1 Initial Inspection

4. Operating Instructions
Follow these steps for accurate and efficient measurement using your tape measure.
4.1 Extending and Retracting the Blade
- To extend the blade, pull the hook end away from the casing.
- To retract the blade, release the hook end. The internal spring mechanism will pull the blade back into the casing.
4.2 Using the Blade Lock
- Extend the blade to the desired length.
- Push the slide lock button forward (typically located on the top of the casing) to engage the lock. This will hold the blade in place.
- To release the lock, pull the slide lock button backward.
4.3 Measuring Techniques
- Outside Measurement: Hook the end of the blade onto the edge of the object. Extend the blade and read the measurement at the desired point. The Tru-Zero hook accounts for its own thickness.
- Inside Measurement: Push the hook end against the inside corner of the object. Extend the blade and read the measurement. The Tru-Zero hook will adjust for its thickness.
- Magnetic Measurement: For metal surfaces, attach the magnetic hook directly to the metal. This allows for stable, single-person measurements, especially useful for pipes, steel beams, or ducts.

5. Maintenance
Proper maintenance ensures the longevity and accuracy of your tape measure.
- Cleaning: Wipe the blade and casing with a dry or slightly damp cloth after use to remove dust, dirt, or debris. Avoid using harsh chemicals or abrasive cleaners.
- Storage: Store the tape measure in a dry environment, away from extreme temperatures and direct sunlight. Ensure the blade is fully retracted before storage.
- Blade Care: Avoid bending or creasing the blade excessively, especially when extending it to its maximum standout. The BladeArmor coating provides protection, but extreme force can still cause damage.
- Hook Inspection: Periodically check the magnetic hook for secure attachment and ensure it moves freely for accurate Tru-Zero measurements.
6. Troubleshooting
This section addresses common issues you might encounter.
- Blade does not retract smoothly:
- Check for dirt or debris inside the casing or on the blade. Clean as described in the Maintenance section.
- Ensure the blade is not bent or kinked.
- Blade lock is not holding:
- Verify the slide lock is fully engaged.
- Inspect the lock mechanism for any obstructions or damage.
- Magnetic hook detaches or is loose:
- While rare, if the hook becomes loose, ensure it is properly seated. If it consistently detaches, contact customer support.
- Inaccurate measurements:
- Ensure the Tru-Zero hook is functioning correctly and moves freely.
- Verify the blade is not damaged or stretched.
