WORKPRO Aluminum Alloy Carpenter Square and Zinc-Alloy Square Ruler Set Instruction Manual

1. Introduction

This manual provides detailed instructions for the safe and effective use of your WORKPRO Aluminum Alloy Carpenter Square and Zinc-Alloy Square Ruler Set. This set includes a 7-inch rafter square and a 12-inch combination square. Please read these instructions carefully before use and retain them for future reference.

2. Product Features

• Durable Material: The rafter square is die-cast from heavy-gauge aluminum alloy, ensuring longevity and accurate measurements. The combination ruler features a zinc alloy head and a stainless steel ruler with a matte finish.
• Clearly Identifiable Scale: Both squares feature low-glare, powder-coated finishes with permanent deep markings and white graduations for maximum readability in various lighting conditions. The stainless steel ruler has a deep etching scale for superior legibility.
• Multiple Graduation: The 7-inch rafter square combines features of a framing square, try square, miter square, and protractor square. The 12-inch combination square's stainless steel ruler includes 1/16", 1/32", and 1mm minimum scale values.
• User-Friendly Design: The rafter square's lipped fence allows for easy bracing against wood edges for straight or angled lines. The combination square features a spring screw for easy detachment of the ruler and smooth sliding for precise measurements.
• Wide Versatility: The combination ruler includes an easy-to-read level vial and a metal scriber. Both squares are accurate at 90 and 45 degrees, and the rafter square can guide cross-cutting lumber.

3. Setup

3.1 Combination Square Setup

1. Inspect Components: Ensure the zinc alloy head and stainless steel ruler are securely attached. The spring screw should allow the ruler to slide smoothly but hold firmly when tightened.
2. Adjusting the Ruler: Loosen the brass spring screw to slide the stainless steel ruler to the desired position. Tighten the screw to lock the ruler in place.
3. Checking the Level: Verify the spirit level bubble is centered when the square is placed on a known level surface.

3.2 Rafter Square Setup

1. Familiarize with Markings: Identify the degree markings, common rafter scales, hip/val rafter scales, and pivot point.
2. Check Lipped Fence: Ensure the lipped fence is clear and free of debris for flush contact with your workpiece.

4. Operating Instructions

4.1 Using the 7-inch Rafter Square

1. Marking 90-Degree Cuts: Place the lipped fence against the edge of your material. Use the straight edge of the square to draw a perpendicular line.
2. Marking 45-Degree Cuts: Align the lipped fence against the material edge. The 45-degree angle is clearly marked on the square's hypotenuse.
3. Using as a Saw Guide: Position the square with its lipped fence against the material edge. The thick aluminum body provides a stable guide for a circular saw to ensure straight and accurate cuts.

4. Scribing Lines: Utilize the 1/4-inch spaced scribing notches and super long scriber slots to mark parallel lines at various distances from the edge.

4.2 Using the 12-inch Combination Square

1. Measuring and Marking: Slide the ruler to the desired measurement and tighten the spring screw. Use the ruler's edge for precise marking.
2. Checking Squareness (90 and 45 Degrees): Place the square head against the edge of your material. The fixed 90-degree and 45-degree angles allow for quick verification of corners and angles.

3. Using the Spirit Level: The integrated level vial allows you to check for horizontal or vertical alignment. Ensure the bubble is centered between the lines for accurate leveling.

4. Using the Scriber: The metal scriber located on the side of the combination head can be used to mark precise lines on various materials.
5. Measuring Depth: Extend the ruler and use the end of the ruler against a surface to measure the depth of a recess or hole.

5. Maintenance

• Cleaning: Wipe down both squares with a clean, dry cloth after each use to remove dust, debris, or moisture. For stubborn grime, use a mild cleaner and dry thoroughly.
• Storage: Store the tools in a dry environment to prevent rust or corrosion, especially for the stainless steel ruler. Keep them in a protective case or tool drawer to avoid damage.
• Checking Accuracy: Periodically check the accuracy of your squares against a known true square or a reliable reference. For the combination square, ensure the ruler slides smoothly and locks securely.

6. Troubleshooting

• Inaccurate Readings: Ensure the tools are clean and free of debris. Verify the ruler on the combination square is tightly secured. Check for any physical damage or bending that might affect accuracy.
• Ruler Sticking/Loose (Combination Square): If the ruler is difficult to slide or too loose, check the spring screw. Clean any accumulated dust or grime from the ruler channel.
• Spirit Level Bubble Not Centered: If the bubble is consistently off-center on a known level surface, the tool may require recalibration or replacement.
