Product Overview

The Williams RBO-810 wrench is constructed from durable alloy steel with a chrome finish, ensuring longevity and resistance to corrosion. Its key features include:

• Double Head Design: Provides two different box-end sizes (1/4-Inch and 5/16-Inch) on a single tool.
• 25-Degree Offset Handle: This ergonomic design allows for clearance over obstructions, providing better access to fasteners in tight or recessed areas.
• Ratcheting Mechanism: Enables continuous rotation of the fastener without removing and repositioning the wrench, significantly speeding up work, especially for long bolts.
• Box End Style: Offers a secure grip on fasteners, reducing the risk of slipping and rounding corners.

Operating Instructions

1. Select Correct Size: Identify the appropriate box-end size (1/4-Inch or 5/16-Inch) that matches your fastener. Ensure the wrench fits snugly to prevent damage to the fastener head.
2. Position the Wrench: Place the box end over the fastener. The 25-degree offset allows you to clear obstacles.
3. Engage Ratcheting Mechanism: The wrench features a reversible ratcheting mechanism. To change the direction of rotation (tightening or loosening), locate the small lever or switch near the ratcheting head and flip it to the desired direction.

4. Apply Force: Apply steady, firm pressure to the handle to turn the fastener. The ratcheting action will allow you to reset your grip without removing the wrench from the fastener.
5. Avoid Over-tightening: Do not use extension bars or excessive force that could damage the wrench or the fastener. For final torque specifications, use a torque wrench.

Maintenance

• Cleaning: After each use, wipe the wrench clean with a dry cloth to remove dirt, grease, and debris. For stubborn grime, use a mild solvent and then wipe dry.
• Lubrication: Periodically apply a light coat of machine oil to the ratcheting mechanism to ensure smooth operation and prevent corrosion. Avoid over-lubrication.
• Storage: Store the wrench in a dry environment to prevent rust. Keep it away from corrosive chemicals.
• Inspection: Regularly inspect the wrench for any signs of wear, damage, or deformation. Discontinue use if any damage is observed and replace if necessary.

Troubleshooting

Problem: Ratcheting mechanism feels stiff or sticky.

Solution: The mechanism may be dirty or lack lubrication. Clean the ratcheting head thoroughly and apply a small amount of light machine oil. Operate the mechanism several times to distribute the lubricant.

Problem: Wrench slips on fastener head.

Solution: Ensure you are using the correct size wrench for the fastener. The wrench should fit snugly. If the fastener head is rounded or damaged, the wrench may not grip properly. Consider using a different type of tool for damaged fasteners.

Problem: Wrench appears bent or damaged.

Solution: Discontinue use immediately. Do not attempt to repair a damaged wrench as it may compromise its strength and safety. Replace the tool.
