2. Safety Information

Always observe basic safety precautions when using hand tools to reduce the risk of injury.

• Wear appropriate personal protective equipment: Always wear safety glasses to protect your eyes from flying debris. Gloves are recommended for hand protection.
• Inspect tools before use: Ensure wrenches are clean, dry, and free from damage. Do not use damaged tools.
• Use the correct size wrench: Always select the correct wrench size for the fastener to prevent rounding the fastener head and potential injury.
• Ensure a secure grip: Maintain a firm grip on the wrench. Avoid using extensions or "cheater bars" unless specifically designed for the tool, as this can overload the wrench and cause breakage.
• Work in a well-lit area: Adequate lighting helps prevent accidents.
• Keep children and bystanders away: Ensure your work area is clear of distractions.
• Store tools safely: After use, clean and store wrenches in their designated roll-up bag in a dry, secure location.

5. Setup and Preparation

1. Unpack the set: Carefully remove the wrench set from its packaging.
2. Inspect for damage: Before first use, visually inspect each wrench for any signs of manufacturing defects or shipping damage. If any damage is found, do not use the tool and contact customer support.
3. Familiarize yourself with sizes: Identify each wrench by its clearly marked size (6mm to 19mm).
4. Prepare the work area: Ensure your work area is clean, well-lit, and free of obstructions.

6. Operating Instructions

The HYCHIKA flexible ratcheting combination wrenches are designed for tightening and loosening nuts and bolts.

1. Select the correct size: Choose the wrench that precisely fits the fastener. Using an incorrect size can damage the fastener and the wrench.
2. Position the wrench:
   • For the open end, slide it over the fastener head.
   • For the ratcheting box end, place it over the fastener. The 12-point design provides a secure grip.
3. Adjust the flexible head (if needed): The ratcheting head can pivot up to 180°. Adjust its angle to best suit the access requirements of your work area.
4. Apply force:
   • To tighten, turn the wrench clockwise.
   • To loosen, turn the wrench counter-clockwise.
   The ratcheting mechanism allows you to turn the fastener without removing the wrench from the bolt head, simply by reversing the direction of your hand movement. There is no switch; the ratchet engages in the direction of applied torque.
5. Maintain control: Apply steady, even pressure. Avoid sudden jerks or excessive force.

7. Maintenance

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

• Cleaning: After each use, wipe down the wrenches with a clean, dry cloth to remove dirt, grease, and moisture. For stubborn grime, a mild degreaser can be used, followed by thorough drying.
• Lubrication: Periodically apply a small amount of light machine oil to the ratcheting mechanism to ensure smooth operation. Wipe off any excess oil.
• Storage: Store the wrenches in their provided 600D canvas roll-up bag. This protects them from dust, moisture, and prevents them from getting lost. Store the bag in a dry, secure place away from direct sunlight and extreme temperatures.
• Inspection: Regularly inspect the wrenches for any signs of wear, cracks, or damage. Replace any damaged tools immediately.
