Safety Warnings
- Work Area: Keep the area clean, well-lit, and free of debris. Do not operate in explosive atmospheres.
- Electrical Safety: Do not expose the tool to rain or wet conditions.
- Personal Safety: Always wear eye protection. Keep hair, clothing, and gloves away from moving parts.
- Battery Safety: Do not short-circuit the battery. Do not dispose of batteries in fire. Charge only with the specified charger.
Battery Charging and Handling
The battery should be charged at temperatures between 0°C and 40°C. The charger indicator light provides status updates:
- Blinking (1s interval): Before charging.
- Continuous Light: Charging in progress.
- Blinking (1s interval): Charging complete.
- Blinking (0.5s interval): Overheat standby (battery too hot).
- Flickering (0.1s interval): Malfunction in battery or charger.
Note: If the battery is hot after use, let it cool before charging. If the battery usage time becomes very short, it may have reached the end of its life.
Operation
Bit Installation and Removal
To install a bit, loosen the sleeve by turning it counter-clockwise (viewed from the front) to open the chuck. Insert the bit, then tighten the sleeve by turning it clockwise.
Rotation and Speed
Use the selector button to choose the rotation direction (R for clockwise, L for counter-clockwise). Use the shift knob to select speed: LOW (0–450/min) for high torque tasks or HIGH (0–1250/min) for fast drilling.
Torque Adjustment
The clutch dial allows you to adjust tightening torque from 1 to 22. Use lower numbers for smaller screws and higher numbers for larger screws or drilling. Align the chosen number with the triangle mark on the tool body.
Maintenance and Inspection
- Tool Inspection: Sharpen or replace dull bits to prevent motor malfunction.
- Mounting Screws: Regularly check that all screws are tight.
- Cleaning: Wipe the tool with a soft, dry cloth or soapy water. Do not use solvents like gasoline or paint thinner.
- Storage: Store in a dry place below 40°C, out of reach of children.
