  • Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

For JS1601 Only
Adjusting the blade clearance (Fig. 2 & 3)
Adjust the clearance between the side blade and the center blade according to the thickness of the workpiece. First use a hex wrench to loosen the screw.
Then use the hex wrench to adjust the clearance by tight-ening or loosening the bolt. There may be a slight differ-ence between clearances of both sides of the center blade. Check the smaller clearance with the thickness gauge and adjust it. When using the thickness gauge to adjust the blade clearance, refer to the table.

  • Workpiece thickness (mm): Marking on thickness gauge
  • Less than 0.8: 0.5
  • 0.8 – 1.3: 1.0
  • More than 1.3: 1.5

After adjusting the clearance, tighten the screw securely. Storing hex wrench (Fig. 4) Store the hex wrench as shown in the figure when not in use.

OPERATION

Lubrication (Fig. 5)
Before operation, lubricate the contact point of the center blade and the pin. To keep good cutting performance, also use a cutting lubricant from time to time during oper-ation.
Operation (Fig. 6 & 7)
Always hold the tool firmly with one hand on housing. Do not touch the metal part. Turn the tool on and set front ends of the side blades on the workpiece. Now simply move the tool forward, keep-ing the side blades flush with the workpiece surface.
NOTE: 

When cutting a small portion of the workpiece, you may have difficulty completing the end of the cut. In that case, try to cut it again, pulling the workpiece back slightly.
