This document provides essential operating and safety instructions for the HiKOKI DV 18DGAL cordless combi drill. Key procedures include proper battery charging, bit installation, and selecting the correct operating mode (drilling or impact drilling). Always ensure the tool is switched off before changing settings or batteries to prevent accidental startup.
Battery charging
Before using the tool, ensure the battery is fully charged. Connect the charger to a power source; the pilot lamp will blink in red. Insert the battery firmly into the charger. The lamp will light continuously while charging and blink when complete. If the lamp flickers rapidly, check for foreign objects in the connector or potential malfunctions.
Operation
- Removing/Inserting Battery: Slide the battery into the tool until it clicks.
- Torque Adjustment: Use the clutch dial to set the desired torque. Do not set the dial between numbers or between the drill mark and the last number.
- Selecting Mode: Use the mode selector to switch between drilling and impact drilling.
- Speed Selection: Use the shift knob to select high or low speed. Only change speed when the motor is stopped.
- Bit Mounting: Insert the bit into the keyless chuck and tighten the sleeve securely.
Maintenance and inspection
Regularly inspect the tool for dull bits, loose mounting screws, and motor cleanliness. Keep the exterior clean by wiping with a soft, dry cloth or soapy water; avoid solvents like gasoline or paint thinner. Store the tool and battery in a dry place below 40°C, out of reach of children. Ensure batteries are fully charged before long-term storage.
Troubleshooting
If the tool fails to operate, check the battery charge and ensure it is securely inserted. If the motor stops suddenly, it may be overloaded; release the switch and remove the cause of the overload. If the drill bit slips, ensure the chuck is tightened properly and the bit size is within the 1.5 mm to 13 mm range.

- Low speed (0-400 min-1) for high torque tasks; High speed (0-1500 min-1) for fast drilling.
- Impact rate (Bpm)
- Determines the hammering frequency for impact drilling in concrete/brick.
- Drill chuck capacity
- The range of bit shank diameters the chuck can securely hold (1.5 mm to 13 mm).
