1. Introduction

This manual provides essential information for the proper use, setup, and maintenance of your DURATECH Flex-Head Double Box End Ratcheting Wrench Set. Please read these instructions carefully before using the product to ensure safe and efficient operation.

The DURATECH 7-in-1 Metric Wrench Set includes two main ratcheting wrenches (14mm and 19mm) and five interchangeable heads (8mm, 10mm, 12mm, 13mm, 17mm), offering versatility for various tasks.

2. Product Features

• 7-in-1 Versatility: The set includes an 8.3-inch flex-head double box end ratcheting wrench with a 14mm end (compatible with 8-12mm replacement heads) and a 19mm end (compatible with 13-17mm replacement heads).
• High-Quality Material: Constructed from chrome vanadium steel with a mirror finish, heat-treated for strength, and chrome plated for corrosion and rust resistance.
• Flex-Head Design: Features a 180° rotating head for accessing fasteners at various angles and bypassing obstacles.
• 72-Tooth Ratchet Gear: Requires only a 5-degree working swing arc, ideal for use in confined spaces.
• Portable Storage: Comes with a dedicated storage box for easy organization and transport of the wrench and its interchangeable heads.

3. Setup and Head Installation

The DURATECH Flex-Head Ratcheting Wrench Set features quick-change interchangeable heads for different fastener sizes.

1. Select Head Size: Identify the correct metric size (8mm, 10mm, 12mm, 13mm, or 17mm) required for your fastener.
2. Install Head: Align the chosen interchangeable head with the appropriate end of the ratcheting wrench (8-12mm heads fit the 14mm end; 13-17mm heads fit the 19mm end). Push the head firmly into the wrench opening until it clicks securely into place.
3. Verify Installation: Gently pull on the installed head to ensure it is securely seated and will not detach during use.
4. Removal: To remove a head, simply pull it out from the wrench end.

4. Operating Instructions

This wrench set is designed for tightening and loosening nuts and bolts in various applications.

1. Choose Correct Size: Ensure the correct interchangeable head or the fixed wrench size (14mm or 19mm) is selected and securely installed for the fastener.
2. Position Wrench: Place the box end of the wrench over the fastener.
3. Adjust Flex-Head: If working in a tight or obstructed area, adjust the 180° flex-head to the desired angle to gain better leverage or access.
4. Ratcheting Action: Apply force to the handle to turn the fastener. The 72-tooth ratcheting mechanism allows for continuous turning without removing the wrench from the fastener, even with a small 5-degree swing arc.
5. Direction Change: To change the direction of the ratcheting action (tightening or loosening), use the directional switch located on the wrench head.

5. Maintenance

Proper maintenance ensures the longevity and performance of your wrench set.

• Cleaning: After each use, wipe the wrenches and interchangeable heads clean with a dry cloth to remove dirt, grease, or debris. For stubborn grime, use a mild solvent and then wipe dry.
• Lubrication: Periodically apply a small amount of light machine oil to the ratcheting mechanism and flex-head joints to ensure smooth operation. Avoid over-lubrication.
• Storage: Store the wrench set and all interchangeable heads in the provided storage box in a dry environment to prevent rust and corrosion. Keep out of reach of children.
• Inspection: Regularly inspect the tools for any signs of wear, damage, or deformation. Do not use damaged tools.

6. Troubleshooting

If you encounter issues with your wrench set, consider the following:

• Head Slippage: Ensure the interchangeable head is fully seated and locked into the wrench. If slippage persists, inspect the head and wrench for wear or damage.
• Ratcheting Mechanism Sticking: Clean the ratcheting mechanism thoroughly and apply a small amount of lubricant. If the issue persists, the internal mechanism may be damaged.
• Flex-Head Stiffness: If the flex-head is stiff, clean the pivot points and apply a small amount of lubricant.
