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.
After adjusting the clearance, tighten the screw securely.
Storing hex wrench (Fig. 6)
Store the hex wrench as shown in the figure when not in
use.
OPERATION
Lubrication (Fig. 7)
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 operation.
OPERATION (Fig. 8)
Turn the tool on and set front ends of the side blades on
the workpiece. Now simply move the tool forward,
keeping the side blades flush with the workpiece surface.
(Fig. 9)
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 the
battery cartridge is removed before attempting to
perform inspection or maintenance.
NOTICE:
• 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 (Fig. 10)
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.
Insert the top end of slotted bit screwdriver into the notch
in the tool and remove the holder cap cover by lifting it up.
(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)
Reinstall the holder cap cover on the tool.
Replacing blades
The service life of the blades varies in terms of the
workpiece to be cut. The following reference tables
indicate the approximate service life of the blades.
When the blades become dull, ask Makita Authorized
Service Centers to replace the blades.
