16. 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. (Fig. 24)
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.
(See "17. LED light warning signals")
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
1 Tool bit biting into material
2 Impact against nails, metal or other hard objects
3 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.
