Prior to Operation

English

1.Power source

Ensure that the power source to be utilized conforms to the power requirements specified on the product nameplate.

2.Power switch

Ensure that the power switch is in the OFF position. If the plug is connected to a power receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3.Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

4.Confirm the direction of bit rotation (Fig. 1)

The bit rotates clockwise (viewed from the rear side) when the reversing switch lever is set to the “R” side position. When the lever is set to the “L” side position, the bit rotates counterclockwise and can be used to loosen and remove screws.

5.Adjusting the tightening depth (Fig. 2)

The tightening depth can be adjusted by turning

locator right and left click feeling.

(1)For hex-head screws:

Mount a hex-head screw on the hex-socket and set the distance between the sub-stopper end and the screw head neck to 1–1.5 mm, as shown in Fig. 3.

(2)For drywall screws:

Mount a drywall screw on the bit, and set the distance between the sub-stopper end and the screw head to 1.5–2 mm, as shown in Fig. 4.

(3)For cross-recessed self-drilling screws:

Mount a self-drilling screw on the bit, and set the distance between the sub-stopper end and the screw head bottom to 1–1.5 mm, as shown in Fig. 5.

6.Mounting the bit

For details, refer to the item “Mounting and dismounting the bit”.

MOUNTING AND DISMOUNTING THE HEX- SOCKET OR THE BIT

1. Dismounting the hex-socket (Fig. 6)

(1)While rotating the Sub-Stopper pull it out from the locator.

(2)Remove the hex-socket, hold it with the opposite

side of bit by hand or vise and pull out the bit with pliers.

2.Dismounting the bit (Fig. 7)

Remove sub-stopper (G) as the same manner of hex- head socket and remove the bit holder, then pull out the bit with pliers.

3.Dismounting the bit (Fig. 8)

Remove the sub-stopper (F) as the same manner of hex-head socket and remove the bit holder, then pull out the bit with pliers.

4.Mounting the hex-socket or the bit

Install the bit in the reverse order to removal.

HOW TO USE THE SCREW DRIVER

1.Switch operation and rotational speed adjustment Bit rotational speed can be adjusted between 0 – 6000/min (W6VM) or 0 – 4500/min (W6V4) or 0 – 3000/min (W6VA4) or 0 – 2600/min (W6VB3) or 0 – 1700/min (W8VB2) varying the degree by which the trigger switch is pulled. Rotational speed increases as the trigger switch is pulled, and reaches a maximum speed of 6000/min (W6VM) or 4500 /min (W6V4) or 3000/min (W6VA4) or 2600 /min (W6VB3) or 1700/min (W8VB2) when the trigger switch is pulled fully.

To facilitate continuous operation, pull the trigger switch and depress the switch stopper. The switch will then remain ON even when the finger is released. By pulling the trigger switch again, the switch stopper disengages and the switch is turned OFF when the trigger switch is released.

2.Screw Driver operation

When the switch is turned ON, the motor starts to run but the hex-socket (or the bit) does not rotate. Attach the hex-socket to the screw head groove, and push the Screw Driver against the screw. The hex-socket then rotates and tightens the screw.

CAUTION

Ensure that the Screw Driver is held truly perpendicular to the head of the screw.

If held at an angle, the driving force will not be fully transferred to the screw, and the screw head and/or hex-socket will be damaged. Hex-socket rotation stops when pushing force is released.

3.Direction of hex-socket rotation

The hex-socket rotates clockwise (viewed from the rear side) when the reversing switch lever is set to the “R” side position. When the lever is set to the “L” side position, the hex-socket rotates counter- clockwise, and can be used to loosen and remove

screws.

CAUTION

Never change the direction of hex-socket (or bit holder) rotation while the motor is running. To do so would seriously damage the motor. Turn the power switch OFF before changing the direction of hex- socket (or bit holder) rotation.

MAINTENANCE AND INSPECTION

1.Inspecting the hex-socket (or bit)

Since continued use of a worn hex-socket (bit) will damage screw heads, replace the hexsocket (bit) with a new one as soon as excessive wear is noticed.

2.Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

3.Maintenance of the motor

The motor unit winding is the very ”heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
