Setup
- Unpacking: Carefully remove the calipers from their packaging. Inspect the tool for any signs of damage during transit.
- Initial Inspection: Check the pivot point and the wing-nut assembly to ensure they are secure and move freely without excessive play. The arms should pivot smoothly.
- Familiarization: Hold the calipers and get a feel for their lightweight design and balance. Practice opening and closing the arms to understand their range of motion.
Operating Instructions
The Kemper Tools Aluminum Calipers are designed for simple and effective measurement of various objects. Follow these steps for accurate use:
1. Measuring Outside Dimensions:
- Open the Calipers: Loosen the wing-nut slightly to allow the caliper arms to move freely.
- Position the Calipers: Place the outer tips of the caliper arms around the object you wish to measure.
- Adjust for Fit: Gently close the arms until they make firm, but not forced, contact with the widest points of the object. Ensure the calipers are perpendicular to the object's surface for an accurate reading.
- Lock the Measurement: Once the desired fit is achieved, carefully tighten the wing-nut to lock the arms in place. This prevents the measurement from changing when the calipers are removed from the object.
- Read the Measurement: Remove the calipers from the object. Use a ruler or tape measure to determine the distance between the outer tips of the locked caliper arms.
2. Measuring Inside Dimensions:
- Open the Calipers: Loosen the wing-nut.
- Position the Calipers: Insert the inner tips of the caliper arms into the opening you wish to measure (e.g., the inside of a pot or a hole).
- Adjust for Fit: Gently open the arms until the inner tips make firm contact with the inner walls of the opening. Ensure the calipers are positioned to measure the true diameter or width.
- Lock the Measurement: Tighten the wing-nut to secure the measurement.
- Read the Measurement: Remove the calipers. Use a ruler or tape measure to determine the distance between the inner tips of the locked caliper arms.
3. Adjusting Hardware Assembly:
The rust-free hardware assembly, primarily the wing-nut and pivot, can be adjusted by hand. If the arms are too loose or too tight when the wing-nut is loosened, you may gently adjust the tension of the pivot screw. Do not overtighten, as this can impede smooth operation or damage the tool.
Maintenance
- Cleaning: After each use, wipe the calipers with a clean, dry cloth to remove any dust, clay, or debris. For stubborn residue, a slightly damp cloth can be used, followed immediately by thorough drying.
- Storage: Store the calipers in a dry place to prevent any potential corrosion, although the hardware is designed to be rust-free. Keep them away from abrasive materials that could scratch the aluminum surface.
- Hardware Check: Periodically check the tightness of the pivot screw and wing-nut. Ensure they are secure but allow for smooth movement when loosened. Do not apply lubricants unless specifically recommended by the manufacturer, as this tool is designed for dry operation.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Calipers arms do not hold position after tightening wing-nut. | Wing-nut not tightened sufficiently, or threads on the wing-nut/pivot screw are worn/stripped. | Ensure the wing-nut is tightened firmly. If the problem persists, inspect the threads for wear. If stripped, the hardware assembly may need replacement. |
| Arms are stiff or difficult to move. | Pivot screw is too tight, or debris is lodged in the pivot mechanism. | Loosen the pivot screw slightly. Clean the pivot area thoroughly to remove any obstructions. |
| Inaccurate measurements. | Improper positioning of calipers, or calipers are damaged/bent. | Ensure calipers are perpendicular to the object and making proper contact. Inspect the arms for any bends or deformities. |
