1. Introduction
Thank you for choosing the DEKO 126-Piece Tool Kit with 8V Cordless Drill. This comprehensive kit is designed for a wide range of DIY projects, home maintenance, and professional tasks. This manual provides essential information for safe operation, proper use, and maintenance of your tools. Please read it thoroughly before first use and keep it for future reference.
2. General Safety Information
Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury.
2.1. Work Area Safety
- Keep your work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.2. Electrical Safety (for Cordless Drill)
- Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Use the specified charging cable (USB-C) and a compatible 5V DC USB power source for charging the drill battery.
2.3. Personal Safety
- Always wear eye protection. Use safety glasses or goggles.
- Wear appropriate personal protective equipment (PPE) such as gloves, dust mask, and hearing protection when necessary.
- Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
2.4. Tool Use and Care
- Do not force the tool. Use the correct tool for your application.
- Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Store idle tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
- Maintain tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool’s operation. If damaged, have the tool repaired before use.

6. Operating Instructions
6.1. Using the Cordless Drill
- Select Rotation Direction: Use the forward/reverse switch (refer to Figure 3) to select the desired rotation.
- Push left for forward rotation (for drilling and tightening screws).
- Push right for reverse rotation (for removing screws).
- Center position locks the trigger for safety.
- Start and Control Speed:
- Hold the drill firmly with both hands if possible, or one hand if lightweight tasks.
- Press the control trigger to start the drill. The LED worklight will illuminate.
- The drill features variable speed control: press the trigger lightly for slower speeds and harder for faster speeds (up to 800 RPM).
- Release the trigger to stop the drill.
- Drilling and Screwdriving Applications:

Figure 4: The 8V cordless drill shown performing various tasks such as drilling into wood, plastic, and soft metal, and tightening/loosening screws. Maximum torque is 12 N·m.
- Drilling: Apply steady, even pressure. For harder materials, start with a slower speed and gradually increase. Ensure the drill bit is appropriate for the material (wood, plastic).
- Screwdriving: Use the appropriate screwdriver bit. Start at a low speed to engage the screw, then increase speed as needed. For loosening, use reverse rotation. The maximum torque is 12 N·m.
6.2. Using Hand Tools
The kit includes a variety of hand tools for common tasks.

Figure 5: Demonstrations of using various hand tools from the kit, including a screwdriver for fastening, a hammer for driving nails, long nose pliers for bending wire, and a tape measure for accurate measurements.
- Screwdrivers: Select the correct type (slotted, Phillips, precision) and size for the screw head to prevent damage to the screw or tool.
- Hammer: Use for driving nails or light demolition. Always wear safety glasses.
- Pliers: Long nose pliers are ideal for gripping, bending, and cutting small wires or objects.
- Adjustable Wrench: Adjust the jaw opening to fit the nut or bolt head snugly before applying force.
- Tape Measure: Extend the tape to measure distances. Ensure it is straight and taut for accurate readings.
- Utility Knife: Use with caution for cutting materials. Always retract the blade when not in use. Change blades when dull for safety and efficiency.
- Hex Keys: Use for fasteners with hexagonal sockets. Ensure the correct size is used to avoid stripping.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your tools.
- Cleaning: After each use, wipe down all tools with a clean, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Do not use harsh chemicals or abrasive cleaners.
- Cordless Drill Care: Keep the ventilation openings of the drill clean to prevent overheating. Do not immerse the drill in water.
- Lubrication: Moving parts of hand tools (e.g., pliers, adjustable wrench) may benefit from occasional light lubrication with a general-purpose oil to ensure smooth operation and prevent rust.
- Storage: Store all tools in the provided durable case in a dry, clean, and secure location, out of reach of children. Ensure the drill battery is partially charged (not fully depleted or fully charged for long-term storage) if storing for extended periods.
- Inspection: Periodically inspect all tools for signs of wear, damage, or loose parts. Replace worn-out bits or blades. Do not use damaged tools.
