Setup
The CRAFTSMAN Torpedo Level requires minimal setup. It is ready for use directly out of its packaging.
- Unpack: Carefully remove the level from its packaging.
- Inspect: Before first use, inspect the level for any visible damage to the body or vials. Ensure the vials are clear and the bubbles move freely.
- Familiarize: Identify the three vials: one for horizontal (level), one for vertical (plumb), and one for 45-degree angles.
Operating Instructions
Using the CRAFTSMAN Torpedo Level is straightforward. The key is to ensure the tool is placed firmly and steadily on the surface being measured.
Horizontal Leveling
- Place the bottom edge of the level flat against the surface you wish to check for levelness.
- Observe the bubble in the center (horizontal) vial.
- For a perfectly level surface, the bubble should be centered precisely between the two indicator lines on the vial.
- If the surface is metal, the rare earth magnets on the base will hold the level in place, allowing for hands-free adjustments.
Vertical Leveling (Plumb)
- Hold the side edge of the level against the vertical surface (e.g., a wall or post).
- Observe the bubble in the end (vertical) vial.
- For a perfectly plumb surface, the bubble should be centered precisely between the two indicator lines on the vial.
45-Degree Angle Leveling
- Place the level against the surface you wish to check for a 45-degree angle.
- Observe the bubble in the 45-degree vial.
- For an accurate 45-degree angle, the bubble should be centered precisely between the two indicator lines on the vial.
Maintenance
Proper care and maintenance will ensure the longevity and accuracy of your CRAFTSMAN Torpedo Level.
- Cleaning: Wipe the level clean with a soft, damp cloth after each use. Avoid abrasive cleaners or solvents that could damage the vials or the level's finish.
- Storage: Store the level in a dry place, away from extreme temperatures and direct sunlight. Protect it from impacts that could affect its accuracy.
- Accuracy Check: Periodically check the level's accuracy. For horizontal, place it on a flat surface, note the bubble position, then rotate the level 180 degrees and place it in the same spot. The bubble should be in the same position. If not, the level may be out of calibration or damaged.
Troubleshooting
If you encounter issues with your torpedo level, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inaccurate Readings | Level is dirty; Vials are damaged; Level is dropped or bent. | Clean the level and vials. Inspect for cracks or leaks. If dropped, perform an accuracy check. If consistently inaccurate, the level may need replacement. |
| Weak Magnetic Hold | Magnets are dirty; Surface is not ferromagnetic; Magnets are damaged. | Clean the magnetic strip on the level. Ensure the surface is suitable for magnetic adhesion. If magnets are physically damaged, the level may need replacement. |
| Bubble does not move freely | Vial is damaged or fluid is frozen. | Inspect the vial for cracks. If used in extremely cold conditions, allow the level to warm up to room temperature. If the issue persists, the level may be damaged. |
