●
Use the bit that fits the cross recess on the screw
head.
Make sure to use an appropriate bit especially
when tightening self drilling screws since using
an inappropriate bit can topple the screws.

OPERATIONAL CAUTIONS

1. Continuous operation
When you perform the striking operation
continuously, the temperature protection circuit
may be activated early. (Refer to "2. Characteristics
of Electronic Pulse Driver" on page 14.)
When the activated temperature protection circuit
stops the tool, the LED light flashes to indicate that
the tool is heated to high temperature. The LED
light goes off automatically after approx. 30
seconds.
When you perform continuous operation, allow the
tool to rest for around 15 minutes at a replacement
of rechargeable battery.
NOTE:
When the tool is stopped by the activated
temperature protection circuit, allow the tool to
cool sufficiently.
You can use the tool again when it cools down.
While the tool is not cooled sufficiently, it cannot
start up by turning the switch to on. The LED light
flashes while the switch is turned on. Please wait
until the tool cools down sufficiently.
Do not touch the nose part of the tool during
continuous operation. It is heated to high
temperature.

9. Work amount possible with one charging
The following table shows the approximate
amount of work to be carried out by the tool with
one charging.
(The number of screws tightened and that of boring
operations differ slightly according to the hardness
of wood or metal, the ambient temperature, the
charger properties, etc.)

2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently,
when the switch trigger is pulled only slightly (low
speed rotation) and the motor is stopped while
continuously driving in screws, the components
of the electronic circuit parts may overheat and be
damaged.
3. Holding the tool and applying the pressing
force
Make sure to hold the tool securely with your both
hands, and keep the tool straight to a screw or bolt.
There is no need to press the tool excessively
against materials.
Be careful not to apply excessive pressing/prying
force to the tool. It may damage the tool.
