Operating Instructions
General Safety Guidelines:
- Always wear appropriate personal protective equipment (PPE), such as safety glasses, when using hand tools.
- Ensure the workpiece is stable and secured before applying force with any tool.
- Never use a tool for a purpose for which it was not designed.
- Do not use damaged or worn tools. Replace them immediately.
- Keep tools clean and free of grease or oil to maintain a secure grip.
Using Sockets and Ratchets:
- Select the Correct Size: Choose a socket that precisely fits the fastener head to prevent rounding.
- Attach to Ratchet: Securely attach the selected socket to the ratchet. For hard-to-reach areas, use the appropriate extension or universal joint.
- Direction: Set the ratchet direction for tightening or loosening using the switch on the ratchet head.
- Apply Force: Apply steady, controlled force. Avoid sudden jerking motions.

Using Wrenches:
- Combination Wrenches: Use the open end for quick engagement and the box end for a more secure grip and higher torque.
- Hex Keys (Allen Wrenches): Insert fully into the hexagonal recess of the fastener. Apply rotational force evenly.

Using Screwdrivers and Bits:
- Match Tip to Fastener: Always select the screwdriver tip or bit that perfectly matches the screw head to prevent cam-out and damage.
- Ratcheting Screwdriver: Insert the desired bit into the magnetic bit adapter. Use the ratcheting mechanism for faster driving or removal of screws.
- Apply Pressure: Apply firm, downward pressure while turning to maintain engagement with the screw head.

Using Pliers:
- Groove Joint Pliers: Adjust the jaw opening to fit the workpiece. Ideal for gripping irregular shapes or pipes.
- Long Nose Pliers: Use for reaching into tight spaces, bending small wires, or holding small components.
- Diagonal Cutting Pliers: Designed for cutting wires. Ensure the wire is within the cutting capacity of the pliers. Do not use for cutting hardened steel.

Maintenance
- Cleaning: After each use, wipe down tools with a clean, dry cloth to remove dirt, grease, and moisture. For stubborn grime, a mild solvent can be used, followed by thorough drying.
- Lubrication: Periodically apply a light coat of machine oil to moving parts of ratchets and pliers to ensure smooth operation and prevent rust.
- Storage: Store all tools in their designated slots within the carrying case. Keep the case in a dry environment to prevent corrosion.
- Inspection: Regularly inspect tools for signs of wear, damage, or corrosion. Replace any compromised tools to maintain safety and performance.
Troubleshooting
Most issues with hand tools can be resolved by ensuring correct usage and maintenance. If you encounter problems:
- Fastener Slipping/Rounding: Ensure you are using the correct size and type of tool (socket, wrench, screwdriver bit) for the fastener. Apply firm, consistent pressure.
- Ratchets Not Engaging: Check the direction switch on the ratchet head. If still not engaging, the internal mechanism may be dirty or worn; clean and lubricate, or consider replacement if severely damaged.
- Stuck or Seized Components: Do not force tools. Apply penetrating oil if necessary and allow time for it to work. Use appropriate leverage, but avoid excessive force that could damage the tool or workpiece.
