• Charge the battery cartridge if not used for more than six months.

Functional Description

CAUTION: Ensure the tool is switched off and the battery cartridge is removed before any adjustments or checks.

Installing or Removing Battery Cartridge

CAUTION: Always switch off the tool before installing or removing the battery cartridge.

CAUTION: Hold the tool and battery cartridge firmly to prevent slipping and damage.

To remove: Slide the cartridge from the tool while sliding the button on the front.

To install: Align the tongue on the cartridge with the groove in the housing and slide it in until it clicks. Ensure the red indicator on the button is not visible, indicating it's fully locked.

CAUTION: Always install the battery cartridge fully until the red indicator is not seen. Otherwise, it may fall out and cause injury.

CAUTION: Do not install the battery cartridge forcibly. If it doesn't slide easily, it's not being inserted correctly.

Indicating the Remaining Battery Capacity

For battery cartridges with "B" at the end of the model number:

Press the check button on the battery cartridge to display remaining capacity via indicator lamps.

Note: Indication may vary slightly based on usage conditions and ambient temperature.

Tool / Battery Protection System

The tool has a protection system that automatically cuts off power to the motor to extend tool and battery life. The tool stops automatically under the following conditions:

• Overload Protection: When the battery draws abnormally high current, the tool stops automatically without indication. Turn the tool off, stop the overloaded application, then turn the tool on to restart.
• Overheat Protection: When the tool/battery overheats, it stops automatically. Let it cool down before restarting.
• Overdischarge Protection: When battery capacity is insufficient, the tool stops automatically. Remove and charge the battery. (Note: Overheat protection for battery works only with batteries with star marking.)

Switch Action

To start: Pull the switch trigger. Speed increases with pressure. Release to stop.

Note: The tool stops automatically if the switch trigger is held for approximately 6 minutes.

Electric Brake: If the tool fails to stop quickly after releasing the trigger, have it serviced.

Operation Details

Lighting up the Front Lamp

CAUTION: Do not look directly into the light source.

Pull the switch trigger to turn on the lamp. It turns off approximately 10 seconds after releasing the trigger.

To keep the lamp off: Pull and release the switch trigger, then press the button for one second within 10 seconds.

To turn the lamp status back on: Press the button again.

Note: If the tool overheats, the light flashes for one minute, then the LED display goes off. Cool down the tool before operating again.

Use a dry cloth to clean the lamp lens; avoid scratching.

Reversing Switch Action

CAUTION: Always check the direction of rotation before operation.

CAUTION: Use the reversing switch only after the tool has completely stopped. Changing direction before stopping may damage the tool.

CAUTION: When not operating, always set the reversing switch lever to the neutral position.

The reversing switch changes rotation direction. Press the lever from side A for clockwise rotation or side B for counterclockwise rotation. When the lever is in the neutral position, the switch trigger cannot be pulled.

Changing the Impact Force

Impact force can be changed in three levels: Hard, Soft, and A mode, allowing suitable tightening for the work. Pressing the button cycles through these levels.

• A mode (Assist Mode): For screws requiring good control. The tool starts with low-speed rotation, then increases speed and impacts. Impact force can be changed for approximately one minute after releasing the switch trigger.

Note: A mode is available only for clockwise rotation. Counterclockwise rotation in A mode uses hard mode speed and impact.

Note: When indicator lamps turn off, the tool is in power-saving mode. Impact force grade can be checked by lightly pulling the trigger without starting the tool.

Note: Impact force grade cannot be changed while pulling the switch trigger.

Assembly and Installation

CAUTION: Ensure the tool is switched off and the battery cartridge is removed before any work.

Installing or Removing Driver Bit/Socket Bit

Use only the specified driver bit/socket bit.

To install: Pull the sleeve, insert the bit as far as it will go, then release the sleeve to secure it.

To remove: Pull the sleeve, then pull the bit out.

Note: If the bit is not inserted fully, the sleeve may not return to its original position, and the bit will not be secured. Re-insert if necessary. Ensure the bit is firmly secured after insertion.

Installing Hook

The hook is for temporarily hanging the tool. It can be installed on either side. Insert into a groove in the tool housing and secure with a screw. To remove, loosen and remove the screw.

Operation and Torque

Proper fastening torque may vary depending on screw/bolt type and size, and workpiece material. The relationship between fastening torque and time is shown in the figures.

Torque Charts

These charts illustrate the proper fastening torque corresponding to fastening time for different bolt diameters and types.

Standard Bolt Torque Chart

Shows torque (N·m and ft·lbs) vs. fastening time (seconds) for bolt diameters M8, M10, M12, M14.

High Tensile Bolt Torque Chart

Shows torque (N·m and ft·lbs) vs. fastening time (seconds) for bolt diameters M8, M10, M12.

Factors Affecting Torque

• Battery cartridge discharge level (lower voltage reduces torque).
• Driver bit or socket bit size (incorrect size reduces torque).
• Bolt characteristics (diameter, torque coefficient, class, length).
• Tool holding manner and driving position material.
