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.
Tool / battery protection system
The tool is equipped with a tool/battery protection system.
This system automatically cuts off the power to extend
tool and battery life. The tool will automatically stop during
operation if the tool or battery is placed under one of the
following conditions:
Overload protection
This protection works when the tool is operated in a
manner that causes it to draw an abnormally high current.
In this situation, turn the tool off and stop the application
that caused the tool to become overloaded. Then turn the
tool on to restart.
Overheat protection
This protection works when the tool or battery is
overheated. In this situation, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
This protection works when the remaining battery capacity
gets low. In this situation, remove the battery from the tool
and charge the battery.
Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 2)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for a few seconds.

Lighted Off
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
• The first (far left) indicator lamp will blink when the
battery protection system works.

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. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
NOTE:
• Even with the switch on and motor running, the bit will
not rotate until you fit the point of the bit in the screw
head and apply forward pressure to engage the clutch.
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 2 mm change in
depth. (Fig. 7)
Adjust the locator so that the distance between the tip of
the locator and the screw head is approximately 3 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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
