FUNCTIONAL DESCRIPTION

CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before adjusting or
checking function on the tool.
Installing or removing battery cartridge
Fig.1
Always switch off the tool before installing or
•
removing of the battery cartridge.
To remove the battery cartridge, slide it from the tool
•
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
•
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red indicator
on the upper side of the button, it is not locked
completely. Install it fully until the red indicator cannot
be seen. If not, it may accidentally fall out of the tool,
causing injury to you or someone around you.
Do not use force when installing the battery
•
cartridge. If the cartridge does not slide in easily, it
is not being inserted correctly.
Battery protection system
(Lithium-ion battery with star marking)
Fig.2
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool to extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
Overloaded:
•
The tool is operated in a manner that causes
it to draw an abnormally high current.
In this situation, release the trigger switch on
the tool and stop the application that caused
the tool to become overloaded. Then pull the
trigger switch again to restart.
If the tool does not start, the battery is
overheated. In this situation, let the battery
cool before pulling the trigger switch again.
Low battery voltage:
•
The remaining battery capacity is too low and
the tool will not operate. In this situation,
remove and recharge the battery.
Switch action
Fig.3
CAUTION:
Before inserting the battery cartridge into the tool,
•
always check to see that the switch trigger
actuates properly and returns to the "OFF" position
when released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Lighting up the front lamp
Fig.4
CAUTION:
Do not look in the light or see the source of light
•
directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out 10 -15 seconds after releasing the
trigger.
NOTE:
Use a dry cloth to wipe the dirt off the lens of lamp.
•
Be careful not to scratch the lens of lamp, or it may
lower the illumination.
Reversing switch action
Fig.5
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
CAUTION:
Always check the direction of rotation before
•
operation.
Use the reversing switch only after the tool comes
•
to a complete stop. Changing the direction of
rotation before the tool stops may damage the tool.
When not operating the tool, always set the reversing
switch lever to the neutral position.
Depth adjustment
Fig.6
The depth can be adjusted by turning the locator. Turn it
in "B" direction for less depth and in "A" direction for
more depth. One full turn of the locator equals 1.5 mm
change in depth.
Adjust the locator so that the distance between the tip of
the locator and the screw head is approximately 1 mm
as shown in the figures. Drive a trial screw into your
material or a piece of duplicate material. If the depth is
still not suitable for the screw, continue adjusting until
you obtain the proper depth setting.
