Safety Instructions

Always follow basic safety precautions when using power tools to reduce the risk of fire, electric shock, and personal injury.

General Safety Rules:

• 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.
• Electrical Safety: Avoid body contact with earthed or grounded surfaces (e.g., pipes, radiators, ranges, refrigerators). Do not expose power tools to rain or wet conditions.
• Personal Safety: Always wear eye protection. Use safety equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection when appropriate. Dress properly; avoid loose clothing or jewelry.
• Tool Use and Care: Do not force the power 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.
• Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. Use power tools only with specifically designated battery packs.

Setup and Assembly

Charging the Battery:

1. Connect the fast charger to a standard power outlet.
2. Slide the 4.0 Ah Li-ion battery pack onto the charger until it clicks into place.
3. Allow 1-2 hours for a full charge. The charger's indicator light will show charging status.
4. Once fully charged, remove the battery from the charger.

Attaching the Battery:

• Align the battery pack with the base of the drill or impact driver.
• Slide the battery pack firmly into place until it locks securely.
• To remove, press the release button on the battery and slide it off.

Installing Bits:

For the 3/8" Cordless Driver-Drill:

• Twist the chuck counter-clockwise to open the jaws.
• Insert the desired drill bit or driver bit into the chuck.
• Twist the chuck clockwise to tighten the jaws securely around the bit. Ensure the bit is centered.

For the 1/4" Impact Driver:

• Pull the quick-release hex collet forward.
• Insert the 1/4" hex shank driver bit.
• Release the collet to lock the bit in place. Pull on the bit to ensure it is secure.

Operating Instructions

General Operation:

• On/Off Switch: Press the trigger switch to turn the tool on. Release to turn it off.
• Variable Speed Control: The speed of the tool is controlled by the amount of pressure applied to the trigger switch. More pressure results in higher speed.
• Forward/Reverse Selector: Push the selector button to the left for forward rotation (driving screws/drilling) and to the right for reverse rotation (removing screws/bits). Center position locks the trigger for safety.
• LED Work Light: The built-in LED light illuminates the work area when the trigger is pressed, improving visibility in dark spaces.

Using the 3/8" Cordless Driver-Drill:

• Torque Settings (20+3 Clutch): Rotate the torque adjustment collar to select the desired torque setting. Lower numbers are for driving small screws or drilling into soft materials, higher numbers for larger screws or harder materials. The drill setting bypasses the clutch for maximum power.
• 2-Speed Adjustment: Use the gear selector switch on top of the tool to choose between low speed (0-1200 RPM) for high torque applications and high speed (0-2200 RPM) for faster drilling.
• Maximum Torque: Up to 45 N.m (400 in-lbs).

Using the 1/4" Impact Driver:

• Variable Speed: 0-3250 RPM.
• Impacts Per Minute (IPM): 0-3450 IPM.
• 4-Speed Adjustment & 3 Scene Modes: The impact driver features multiple speed settings and scene modes that can be easily switched to adapt to different fastening tasks, providing precise control for various materials and screw sizes.
• High Torque: Up to 1950 in-lbs (220 N.m).

Maintenance

Regular maintenance ensures the longevity and optimal performance of your tools.

• Cleaning: After each use, wipe down the tools with a clean, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep ventilation openings clear of dust and debris.
• Storage: Store the tools, batteries, and charger in a cool, dry place, away from direct sunlight and moisture. Use the provided carrying bag for organized storage and transport.
• Battery Care: Do not store batteries in a discharged state. Recharge them periodically if not used for extended periods. Avoid exposing batteries to extreme temperatures.
• Brushless Motor: The tools feature brushless motors, which require less maintenance compared to brushed motors as there are no carbon brushes to replace.
