Setup and Assembly

The GRR-RIPPER GR-100 comes with illustrated instructions for assembly. Follow these steps to prepare your push block for use:

1. Unpack Components: Carefully remove all parts from the packaging. Verify that all components listed in the included instructions are present.
2. Assemble Handle: Attach the adjustable handle to the main body of the GRR-RIPPER. Ensure it is securely fastened but allows for comfortable adjustment.
3. Adjust Center Leg: The Center Leg is adjustable to accommodate various material widths. Loosen the green knob to slide the leg to the desired position, then tighten to secure. This allows for cutting widths as thin as 1/4 inch (6.35mm) and up.
4. Set Balance Support: The Balance Support helps stabilize tricky cuts by matching the stock thickness. Adjust it to provide firm contact with the workpiece, ensuring stability and preventing tipping.
5. Inspect Green Grr-rip Pads: Ensure the high-friction green pads are clean and free of debris for optimal grip.

Operating Instructions

The GRR-RIPPER GR-100 provides superior control and safety across various woodworking machines. Its 3-directional force system (downward, inward, and forward pressure) helps prevent kickback and ensures precise cuts.

General Operation Principles:

• 3-Directional Force: Apply downward pressure to keep the workpiece flat, inward pressure to keep it against the fence, and forward pressure to feed it through the blade.
• Kickback Prevention: The GRR-RIPPER's design and grip virtually eliminate kickback by maintaining constant control over both the keeper and off-cut pieces.
• Precision Cutting: Achieve cuts as thin as 1/4 inch (6.35mm) with accuracy, without needing to readjust your fence.

The GRR-RIPPER applies three directions of force for total control over the workpiece.

The GRR-RIPPER helps virtually eliminate kickback, allowing for safe ripping as thin as 1/4 inch and up.

Applications:

Router Tables: Achieve precise control for both fence-guided and freehand routing operations.

Band Saws: Use the GRR-RIPPER on its side for resawing, ensuring no blade drift and consistent results.

Jointers: Feed material over the cutter head with controlled downward pressure for perfectly flat faces.

Continuous Feeding: Using two GRR-RIPPERs allows for continuous feeding of long stock, preventing burning and blade marks caused by inconsistent feed rates.

The GRR-RIPPER is designed for precise cutting of small parts, thin rips, and tricky cuts, with an adjustable cutting width of 1/4 inch and up.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your GRR-RIPPER GR-100.

• Cleaning: After each use, wipe down the GRR-RIPPER, especially the green high-friction pads, to remove sawdust, resin, and other debris. A damp cloth can be used, but ensure the pads are dry before storage.
• Pad Inspection: Periodically inspect the green Grr-rip pads for signs of wear, damage, or hardening. Worn pads may reduce grip effectiveness. Replacement pads are available from MICROJIG.
• Hardware Check: Ensure all knobs and fasteners are tight. Do not overtighten, as this may damage the plastic components.
• Storage: Store the GRR-RIPPER in a clean, dry place away from direct sunlight and extreme temperatures to preserve the integrity of the materials.
