CAUTION
○ If the battery is charged while it is heated because
it has been left for a long time in a location subject to
direct sunlight or because the battery has just been
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 is equipped with a Reactive Force Control
(RFC) feature that reduces jerking of the tool body.
If the tool bit is suddenly overburdened, any jerking of the
tool body is reduced by activation of the slip clutch or by
stopping of the motor by the sensor built into the tool body.
If the motor is stopped because of overburdening detection
by the controller, this is indicated by blinking of the remaining
battery lamp while the switch is pulled. (Fig. 20)
Because the RFC feature may not activate or its performance
may be insuffi cient depending on the working environment
and conditions, be careful not to suddenly overburden the
tool bit while operating.
● 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
