Charging the Battery
The Li-ion batteries are supplied partially charged, and must be
charged to full capacity using the battery charger provided with the
drill before using the drill for the first time.
Caution: Only use the battery charger provided with
the drill. Only this battery charger is matched to the
Li-ion batteries supplied with your power tool.
Danger: Ensure that the voltage of the power supply
corresponds with the data given on the nameplate of
the battery charger.
Danger: Only use the charger in a dry environment. The
charger is not waterproof. Never attempt to charge the
battery under water.
A battery can be charged at any time without reducing its service
life. This is because the battery charger detects the charging
condition of the battery, and charges it with the optimum current
according to its temperature and voltage. This lengthens the
battery life and leaves it fully charged when stored in the charger.
Interrupting the charging procedure does not damage the battery.
1. Connect the mains plug of the battery charger to an electrical
outlet. A steady green light on the battery charger indicates
that the charger is ready for operation.
2. Press the battery charger’s CHOGORI connector into the socket

Operating the Drill
Switching the Drill On or Off
♦Press the On/Off trigger, and keep it pressed. You can increase
the speed of the drill by increasing the pressure on the switch.
To switch off the drill, release the On/Off trigger.
Note: When the On/Off trigger is not pressed, the
spindle and the tool holder are locked so that the drill
can be used as a screwdriver when the battery is dead.
Selecting the Gear Speed
1. Set the rotational direction switch to the middle position.
Caution: To minimize the risk of accidental activation,
always ensure the rotational direction switch is in the
neutral (middle) position before performing any
maintenance work on the drill, as well as during
transportation and storage.
2. Do one of the following:
⬥Push the gear selector toward the keyless chuck to select
low speed.
⬥Push the gear selector away from the keyless chuck to
select high speed.
Caution: If the gear selector cannot be pushed all the
way, lightly turn the chuck. The drill has a speed gear
clutch, and the gear teeth sometimes hit together,
causing the gear selector to stick. Turning the chuck
releases the teeth and frees the gear selector. Do not
force the gear selector when it is stuck, as this may
break the gears.
13

Selecting the Torque
1. Set the rotational direction switch to the middle position.
Caution: To minimize the risk of accidental activation,
always ensure the rotational direction switch is in the
neutral (middle) position before performing any
maintenance work on the drill, as well as during
transportation and storage.
2. Turn the torque setting ring until the desired torque setting is
aligned with the triangle on the drill body.
Reversing the Rotational Direction
The rotational direction switch is used to control the rotational
direction of the drill. The rotational direction can only be changed
when the On/Off trigger is not pressed.
1. Ensure that the On/Off trigger is not pressed.
2. Do one of the following:
⬥For drilling and driving in screws, push the rotational
direction switch all the way to the left.
⬥For loosening and unscrewing screws and nuts, push the
rotational direction switch all the way to the right.
⬥To deactivate rotation and only operate the LED flashlight,
push the rotational direction switch to the middle, which
is the neutral position.
14

Performing Drill Operations
1. Secure small workpieces using a vise or similar device.
2. Lightly press the tool tip against the workpiece. Excessive force
will damage the tool tip and will not increase the drilling speed.
3. Hold the drill firmly and carefully as the bit begins to break
through the workpiece.
4. If the drill bit gets stuck, release it by reversing the rotational
direction.
Note: When drilling wood, use a guide screw to pull the
drill bit into the workpiece for best results.
Note: When drilling metals, make an indentation at the
point to be drilled to prevent the drill from slipping. For
all metals other than brass and iron, use sufficient
cutting lubricant during drilling.
