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'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 0.1 seconds). (Fig. 15)
(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.

MAINTENANCE AND INSPECTION
WARNING
Be sure to turned off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the tool
Since use of as dull tool will degrade effi ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. Cleaning on the outside
When the power tool is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
LED Light Display
On 0.1 second/off 0.1 second
(rapid blinking)
Blinks for approximately 3 seconds after
the switch has been released.
On 0.5 second/off 0.5 second
(slow blinking)
Blinks while protection is in eff ect.
● 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. If any of the safeguard
functions are triggered during operation, the LED light will
blink as described in Table 5. When any of the safeguard
functions are triggered, immediately remove your fi nger
from the switch and follow the instructions described under
corrective action.
Table 5
If the operating with the shift knob set on "2",
adjust to "1" and continue operation.
Remove the cause of the overburdening.
Remove the cause of the overburdening.
When operating the tool, fi rmly hold the tool to
make sure it doesn't jerk.
Allow the tool and battery to thoroughly cool.
6. Storage
Store the power tool and battery in a place in which
the temperature is less than 40°C and out of reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
