The thickness of material to be cut depends upon the 
tensile strength of the material itself. The groove on the 
die holder acts as a thickness gauge for allowable 
cutting thickness. Do not attempt to cut any material 
which will not fit into this groove. 

Cutting line 

The notch in the die holder indicates your cutting line. 
Its width is equal to the cutting width. Align the notch to 
the cutting line on the workpiece when cutting.

CAUTION: 

• 

Before inserting the battery cartridge into the tool, 
always check to see that the slide switch actuates 
properly and returns to the "OFF" position when 
the rear of the slide switch is depressed. 

• 

Switch can be locked in "ON" position for ease of 
operator comfort during extended use. Apply 
caution when locking tool in "ON" position and 
maintain firm grasp on tool. 

To start the tool, slide the slide switch toward the "I 
(ON)" position. For continuous operation, press the front 
of the slide switch to lock it. 
To stop the tool, press the rear of the slide switch, then 
slide it toward the "O (OFF)" position.

Battery cartridge replacing signal

 

 

When the battery power is almost used up 
during operation, the red lamp lights up and 
the tool stops immediately. Replace the 
battery with fully charged one when the red 
lamp lights up. 

 

Accidental re-start preventive function

 

 

Even if the battery cartridge is inserted on the 
tool with the slide switch in the "I (ON)" position, 
the tool does not start. At this time, the lamp 
flickers slowly and this shows that the 
accidental re-start preventive function is at work. 

 

To start the tool, first slide the slide switch 
toward the "O (OFF)" position and then slide 
it toward the "I (ON)" position. 

ASSEMBLY 

 

CAUTION: 

• 

Always be sure that the tool is switched off and the 
battery cartridge is removed before carrying out 
any work on the tool.
