Makita BLS820 Positioning kerf board, Maintaining maximum cutting capacity

Positioning kerf board

This tool is provided with the kerf boards in the turn base to

minimize tearing on the exit side of a cut. The kerf boards are

factory adjusted so that the saw blade does not contact the

kerf boards. Before use, adjust the kerf boards as follows:

First, remove the battery cartridge. Loosen all the screws

(2 each on left and right) securing the kerf boards. Re-tighten

them only to the extent that the kerf boards can still be easily

moved by hand. Lower the handle fully and push in the stop-

per pin to lock the handle in the lowered position. Adjust the

kerf boards so that the kerf boards just contact the sides of

the blade teeth. Tighten all the screws (do not tighten firmly).

After adjusting the kerf boards, release the stopper pin and

raise the handle. Then tighten all the screws securely.

CAUTION:

•Before and after changing the bevel angle, always adjust

the kerf boards as described above.

Maintaining maximum cutting capacity

This tool is factory adjusted to provide the maximum cutting

capacity for a 216 mm (8-1/2”) saw blade.

When installing a new blade, always check the lower limit

position of the blade and if necessary, adjust it as follows:

First, remove the battery cartridge. Lower the handle com-

pletely. Use the socket wrench to turn the adjusting bolt until

the periphery of the blade extends slightly below the top sur-

face of the turn base at the point where the front face of the

guide fence meets the top surface of the turn base.

With the battery cartridge removed, rotate the blade by hand

while holding the handle all the way down to be sure that the

blade does not contact any part of the lower base. Re-adjust

slightly, if necessary.

CAUTION:

•After installing a new blade, always be sure that the

blade does not contact any part of the lower base when

the handle is lowered completely. Always do this with the

battery cartridge removed.
