5. Setup

Before installing grommets, ensure your workspace is clean and well-lit. Prepare your material and the grommet tool as follows:

  1. Inspect the Tool: Check the grommet tool for any damage or loose parts. Ensure the molds are clean.
  2. Prepare Grommets: Separate the eyelets (the top part with the barrel) from the washers (the flat ring).
  3. Material Preparation: Lay your material (fabric, tarp, leather) flat. For thicker materials, pre-punching holes is recommended using the included 12mm hole cutter and gasket. Place the gasket under the material to protect your work surface.
  4. Insert Molds (if necessary): The tool comes with 12mm molds pre-installed. If you need to change sizes (for other kits), ensure the correct molds are securely in place. The magnetic design assists in holding the molds.

6. Operating Instructions

Follow these steps to install grommets using your Amliber Ratchet Grommet Tool:

  1. Unlock the Handle: Press the unlock handle or release mechanism to open the tool jaws.
  2. Place Washer: Place one washer into the lower mold of the tool. The magnetic design will help hold it in place.
  3. Place Eyelet: Place one eyelet onto the upper mold, ensuring the barrel faces downwards towards the washer. The magnetic design will secure it.
  4. Position Material: Carefully position the material between the upper and lower molds, aligning the desired grommet location with the center of the molds. If a hole was pre-punched, align the hole with the eyelet barrel.
  5. Press the Handle: Slowly and firmly press the handles together. The ratchet mechanism will engage, allowing you to apply consistent pressure with less effort. Continue pressing until the grommet is fully set and the tool clicks or reaches its maximum closure.
  6. Release and Inspect: Release the handle. The self-locking mechanism will disengage. Carefully remove the material and inspect the installed grommet to ensure it is securely crimped and flat.
  7. Repeat: For additional grommets, repeat steps 1-6.

7. Maintenance

Proper maintenance will extend the life of your grommet tool:

  • Cleaning: After each use, wipe down the tool with a clean, dry cloth to remove any dust or debris.
  • Lubrication: Periodically apply a light machine oil to the pivot points and ratchet mechanism to ensure smooth operation.
  • Storage: Store the tool and grommets in their original packaging or a suitable storage box in a dry environment to prevent rust and damage.
  • Hole Cutter Care: The included hole cutter may dull over time, especially with frequent use on tough materials. Sharpen or replace the cutter as needed to maintain optimal performance.

8. Troubleshooting

ProblemPossible CauseSolution
Grommet not fully crimped or looks uneven.Insufficient pressure applied; material too thick; grommet or washer misalignment.Ensure full pressure is applied until the ratchet mechanism completes its cycle. For very thick materials, consider pre-punching the hole. Verify grommet and washer are perfectly aligned before pressing. Sometimes, rotating the tool and pressing again can help.
Hole cutter is dull or not cutting cleanly.Normal wear and tear from use, especially on dense materials.Sharpen the hole cutter or replace it if severely worn. Ensure the gasket is used underneath the material to provide a clean cutting surface.
Tool handles stick or are difficult to press.Lack of lubrication; debris in the mechanism.Clean the tool thoroughly and apply a light machine oil to all moving parts and pivot points.
Grommets fall out or are loose.Improper crimping; incorrect grommet size for material thickness.Ensure the grommet is fully crimped. If the material is too thin, the grommet may not hold securely. Consider adding a reinforcing layer to the material.
