2. Setup

Before using your WOODRIVER Wheel Marking Gauge, ensure all components are present and in good condition.

1. Unpacking: Carefully remove the marking gauge from its packaging. Verify that the brass head, 8-inch steel rod, and hardened bevel edge marking wheel are included. The marking wheel is pre-installed at one end of the steel rod.
2. Familiarization: Identify the knurled knob on the brass head. This knob is used to loosen and tighten the brass head, allowing it to slide along the steel rod for depth adjustment.
3. Initial Inspection: Check the marking wheel for sharpness and ensure it rotates freely. Inspect the steel rod for any obstructions that might hinder the smooth movement of the brass head.

3. Operating Instructions

Follow these steps for accurate and consistent marking:

1. Adjusting the Marking Depth:

   Loosen the knurled knob on the brass head by turning it counter-clockwise. Slide the brass head along the steel rod to the desired measurement. The steel rod features etched markings to assist with approximate settings. For precise settings, it is recommended to use an external ruler or a reference piece of wood.

2. Securing the Setting:

   Once the brass head is positioned at the correct depth, tighten the knurled knob firmly by turning it clockwise. Ensure the head is securely locked in place to prevent any movement during the marking process. The marking wheel should be perpendicular to the surface you intend to mark.
3. Making a Mark:

   Hold the brass head firmly against the edge of your workpiece. Apply consistent, gentle pressure to the gauge and slide it along the edge of the wood. The hardened bevel edge marking wheel will score a clean, visible line on the wood surface. This tool is effective for marking both along the grain and across the grain.

4. Maintenance

Proper maintenance ensures the longevity and accuracy of your marking gauge.

• Cleaning: After each use, wipe down the steel rod and brass head with a clean, dry cloth to remove any wood dust, resin, or debris. This prevents buildup that could affect accuracy or smooth operation.
• Marking Wheel Sharpness: Periodically inspect the hardened bevel edge marking wheel. If the lines produced become faint or ragged, the wheel may be dull. A dull wheel may require replacement or professional sharpening to restore optimal performance.
• Storage: Store the marking gauge in a dry environment to prevent corrosion of the steel components.
• Knob Tightening: Avoid overtightening the knurled knob excessively, as this could potentially wear down the measurement markings on the steel rod over time. Tighten only enough to secure the brass head firmly.
