Safety and Maintenance
Important: Always use genuine HiKOKI batteries. Do not short-circuit the battery terminals. Keep the tool and battery terminals free of dust and metal shavings. Store the tool in a place where the temperature is below 40°C and out of reach of children. If the tool is overloaded or overheated, the protection circuit will stop the motor; allow the tool to cool before resuming.
Troubleshooting
If the LED light blinks, a safeguard function has been triggered. Overload Protection: Adjust shift knob to LOW or remove the cause of overload. Temperature Protection: Allow the tool and battery to cool. Low Voltage Protection: Recharge the battery.
