used, the charge indicator lamp of the charger lights for
0.3 seconds, does not light for 0.3 seconds (off for 0.3
seconds). In such a case, fi rst let the battery cool, then
start charging.
○ When the charge indicator lamp fl ickers (at 0.2-second
intervals), check for and take out any foreign objects in
the charger's battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○ Since the built-in micro computer takes about
3 seconds to confi rm that the battery being charged with
UC18YSL3 is taken out, wait for a minimum of 3 seconds
before reinserting it to continue charging. If the battery
is reinserted within 3 seconds, the battery may not be
properly charged.

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. 17)
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 "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
Also, other causes include any combination of the
aforementioned.
● When the reactive force control (RFC) is triggered

pulled, if any of the safeguard functions are triggered
during operation, the LED light will blink as described in

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.
