MOUNTING AND OPERATION

REACTIVE FORCE CONTROL

This product features a reactive force control (RFC) to minimize the danger of twisting the operator’s arms when tool itself suddenly jerks during operation.
When the tool bit is suddenly overburdened, the tool itself may react to the motor’s force and twist in the opposite direction of the motor’s rotation, which could result in injury. When the tool’s built-in control detects a reactive force, it stops the motor’s output before the entire tool jerks to lessen the twisting of the operator’s arms.
When this function activates, it will be indicated by the LED light blinking (0.1-second blinks/off 0.5 seconds) while the switch is pulled.
However, as the function may not activate depending on situations or conditions during operation, so care should be taken to avoid any sudden overburdening of the tool bit when operating the tool.

Possible causes of sudden overburdening

• Tool bit biting into material.
• Impact against nails, metal or other hard objects Tasks involving prying or any excess application of pressure etc.
• Also, other causes include any combination of the aforementioned.
• When the reactive force control RFC is triggered.
• When the RFC is triggered and the motor stops, turn off the tool’s switch and remove the cause of the overburdening before continuing operation.

LED LIGHT WARNING SIGNALS

This product features functions that are designed to protect the tool itself as well as the battery. While the switch is pulled, if any of the safeguard functions are triggered during operation, the LED light will blink as described . When any of the safeguard functions are triggered, immediately remove your fi nger from the switch and follow the instructions described under corrective action.
