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 trig-
ger 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 installing 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. The tool
speed is increased by increasing pressure on the switch
trigger. Release the switch trigger to stop.
NOTE:
• The tool will stop three minutes after pulling the switch
trigger.
Lighting up the front lamp (Fig. 4 & 5)
CAUTION:
• Do not look in the lamp or see the source of lamp
directly.
Every time the lamp button
pressed, the lamp status is alternatively changed from
the ON to the OFF and from the OFF to the ON.
With the lamp button in the ON status, pull the switch trig-
ger to turn on the lamp. To turn off, release it and the
lamp goes out approximately 10 seconds after releasing.
With the lamp button in the OFF status, even if the trigger
is pulled, the lamp will not light on.
NOTE:
• To make sure the status of lamp, pull the trigger. When
the lamp lights up by pulling the switch trigger, the lamp
switch is in the ON status. When the lamp does not
come on, the lamp switch is in the OFF status.
• During the operation of switch trigger, the lamp status
cannot be changed.
• For approximately 10 seconds after releasing the
switch trigger, the lamp status can be switched.

Reversing switch action (Fig. 6)
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 counter-
clockwise 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.
Speed change (Fig. 7)
NOTICE:
• Always set the speed change lever fully to the correct
position. If you operate the tool with the speed change
lever positioned halfway between the "1" side and "2"
side, the tool may be damaged.
• Do not use the speed change lever while the tool is
running. The tool may be damaged.
• Do not force the lever to "1" side with impact driver
mode. The tool may be damaged.
To change the speed, first switch off the tool and then
slide the speed change lever to the "2" side for high
speed or "1" side for low speed. Be sure that the speed
change lever is set to the correct position before opera-
tion. Use the right speed for your job.
When turning the action mode changing ring to impact
driver mode, set the speed change lever to the "2" side.
Selecting the action mode (Fig. 8)
This tool employs an action mode changing ring. Select
one of the 4 modes suitable for your work need by turn-
ing this ring.
When driving wood screws or bolts, point the arrow at the
mark for impact driver mode. The impact force can be
adjusted on the LED display.
When drilling into concrete or tiles, point the arrow at the
mark for hammer drill mode.
When drilling into wood or metal, point the arrow at the
mark for drill mode.
When driving small wood screws or machine screws,
point the arrow at the
fastening torque can be adjusted on the LED display.
CAUTION:
• Always set the arrow correctly to either mode mark. If
you operate the tool with the action mode changing ring
positioned halfway between the mode marks, the tool
may be damaged.
• When turning the action mode changing ring, make
sure that the tool stops. If the ring does not easily
move, pull the switch trigger slightly to rotate the spin-
dle and then move the ring.
• In the hammer drill mode or drill mode, the blowing
force or torque is not adjustable. In those modes, the
number on the LED display will be off.
