ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Adjusting the blade clearance (Fig. 2 & 3)
For JS1660 Only
Adjust the clearance between the side blade and the
center blade according to the thickness of the workpiece.
First use a screwdriver 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 (A) and (B).
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)
Less than 0.8
0.8 – 1.3
More than 1.3
After adjusting the clearance, tighten the screw securely.

OPERATION

Lubrication (Fig. 4)
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. 5 & 6)
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.
CAUTION:
• 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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing blades
The service life of the blades varies in terms of the work-
piece to be cut. The following reference tables indicate
the approximate service life of the blades.
When the blades become dull, ask Makita Authorized

Replacing carbon brushes (Fig. 7 & 8)
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
