Feature

Purpose

Wood mode *1

3,800 min

-1

 (/min)

This mode helps to prevent a screw from falling at 

the beginning of driving. 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.

Tightening long screws. 

Bolt mode (reverse rota-

tion auto stop) *1 *2

3,800 min

-1

 (/min)

This mode helps to prevent a bolt from falling off. 

When loosening a bolt with the tool driving in coun-

terclockwise rotation, the tool automatically stops 

after the bolt/nut gets enough loosened. The stroke 

of the switch trigger to reach maximum speed will 

become short in this mode.

Loosening bolts.

T mode (1) *1

– 

(The tool stops rotating 

soon after impact starts.)

This mode helps to prevent the screws from 

over-tightening. It also accomplishes quick oper-

ation and good finish at the same time. The tool 

drives a screw with high-speed rotation and stops 

soon after the tool starts to impact.

NOTE:  

The timing to stop the driving varies depending 

on the type of the screw and material to be 

driven. Make a test driving before using this 

mode.

Driving self-drilling 

screws to a thin metal 

plate with good finish.

T mode (2) *1

2,600 min

-1

 (/min)

This mode helps to prevent the screws from 

breakage and stripping. It also accomplishes quick 

operation and good finish at the same time. The tool 

drives a screw with high-speed rotation and slows 

down the rotation when the tool starts to impact.

NOTE:  

Release the switch trigger as soon as the tight-

ening finished to avoid overtightening.

Driving self-drilling 

screws to a thick metal 

plate with good finish.

*1 : Automatic speed control works only when the switch trigger is fully pulled.

*2 : Reverse rotation auto stop works only when the tool is driving in counterclockwise rotation.

NOTE:

 When none of the lamp on the panel is lit, pull the switch trigger once before pressing the button 

.

NOTE:

 All lamps on the switch panel go out when the tool is turned off to save the battery power. The type of the 

application mode can be checked by pulling the switch trigger to the extent that the tool does not operate.
