Speed change

NOTICE:

 

Use the speed change knob only after 

the tool comes to a complete stop.

 Changing the 

tool speed before the tool stops may damage the tool.

NOTICE:

 

Always set the speed change knob 

carefully into the correct position.

 If you operate 

the tool with the speed change knob positioned half-
way between the position 1 and the position 2, the 
tool may be damaged.

NOTICE:

 

If the rotation speed significantly 

decreases during operation in the high speed 
mode, stop the tool and change the mode to the 
low speed mode.

 Otherwise, the motor may get 

overloaded and cause a malfunction or fire.

Two speed ranges can be preselected with the speed 
change knob.
To change the speed, turn the speed change knob so 
that the pointer points to the position 1 for low speed 
mode or the position 2 for high speed mode.
