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

Changing the impact force

► Fig.8: 1. Hard 2. Soft 3. A mode 4. Changed in three steps 5. Button
You can change the impact force in three steps: hard, soft, and A mode.
This allows a tightening suitable to the work.
Every time the button is pressed, the number of blows changes in three steps.
“A mode (assist mode)” is an easy-to-use mode for driving screws with good control.
In this mode, the tool drives a screw with low-speed rotation at first. After the tool starts to impact, the rotation speed increases and reaches the maximum speed.
You can change the impact force within approximately one minute after releasing the switch trigger.

NOTE: A mode is available only when the tool rotates clockwise. When rotating counterclockwise in A mode, the impact force and speed are the same as hard mode.
NOTE: When all lamps on the switch panel go out, the tool is turned off to save the battery power. The impact force grade can be checked by pulling the switch trigger to the extent that the tool does not operate.
NOTE: While pulling the switch trigger, the impact force grade cannot be changed.

OPERATION

► Fig.13
The proper fastening torque may differ depending upon the kind or size of the screw/bolt, the material of the workpiece to be fastened, etc. The relation between fastening torque and fastening time is shown in the figures.
Standard bolt

1.  Fastening time (second)
2. Fastening torque
3.  Proper fastening torque corresponding to each bolt diameter

High tensile bolt 

 

1. Fastening time (second)
2. Fastening torque
3.  Proper fastening torque corresponding to each bolt diameter

Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the tool to the extent that the bit will not slip off the screw and turn
the tool on to start operation.
NOTICE: If you use a spare battery to continue the operation, rest the tool for at least 15 min.
NOTE: Use the proper bit for the head of the screw/ bolt that you wish to use.
NOTE: When fastening an M8 or smaller screw, choose a proper impact force and carefully adjust the pressure on the switch trigger so that the screw is not damaged.
NOTE: Hold the tool pointed straight at the screw.
NOTE: If the impact force is too strong or you tighten the screw for a time longer than shown in the figures, the screw or the point of the driver bit may be overstressed, stripped, damaged, etc. Before starting your job, always perform a test operation to determine the proper fastening time for your screw.

The fastening torque is affected by a wide variety of factors including the following. After fastening, always check the torque with a torque wrench.

1.  When the battery cartridge is discharged almost completely, the voltage will drop and the fastening torque will be reduced.
2. Driver bit or socket bit
   Failure to use the correct size driver bit or socket bit will cause a reduction in the fastening torque.
3. Bolt
   • Even though the torque coefficient and the class of bolt are the same, the proper fastening torque will differ according to the diameter of the bolt.
   • Even though the diameters of bolts are the same, the proper fastening torque will differ according to the torque coefficient, the class of bolt, and the bolt length.
4. The manner of holding the tool or the material of the driving position to be fastened will affect the torque.
5. Operating the tool at a low speed will cause a reduction in the fastening torque.
