Operation; Maintenance; Optional Accessories - Makita JS3201 Instruction Manual

Install the upper blade and tighten the upper blade
securing bolt with the hex wrench. Press up on the upper
blade while tightening it. (Fig. 4)
After securing the upper blade, be sure that there is no
gap left between the upper blade and the beveled surface
of the blade holder. (Fig. 5)
Then install the lower blade like the upper blade while
adjusting the clearance between the upper blade and
lower blades. When performing this adjustment, the upper
blade should be in the lowered position. (Fig. 6)
First, semi- tighten the lower blade securing bolt, then
insert the thickness gauge for the desired clearance. The
cutting thickness is indicated on the thickness gauge so
the combinations shown in the table below should be
used. Work the lower blade positioning bolt on the yoke
until the clearance is such that the thickness gauge
moves only with some difficulty. Then firmly tighten the
lower blade securing bolt. Finally, tighten the hex nut to
secure the lower blade positioning bolt.

when performing the tool.
Holding material (Fig. 8)
The materials for cutting should be fastened to the
workbench by means of workholders.

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.
The tool and its air vents have to be kept clean. Regularly
clean the tool's air vents or whenever the vents start to
become obstructed.
Replacing carbon brushes
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. (Fig. 11)
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. (Fig. 12)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
