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
First, unplug the tool. 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 stopper pin to
lock the handle in the lowered position. Loosen two clamp screws which
secure the slide poles. Pull the carriage toward you fully. Adjust the kerf boards
so that the kerf boards just contact the sides of the blade teeth. Tighten the
front screws (do not tighten firmly). Push the carriage toward the guide fence
fully and adjust the kerf boards so that the kerf boards just contact the sides of
blade teeth. Tighten the rear screws (do not tighten firmly).
After adjusting the kerf boards, release the stopper pin and raise the handle.
Then tighten all the screws securely.
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 190
mm saw blade.
When installing a new blade, always check the lower limit position of the blade
and if necessary, adjust it as follows:
First, unplug the tool. Push the carriage toward the guide fence fully and lower
the handle completely. Use the socket wrench to turn the adjusting bolt until
the periphery of the blade extends slightly below the top surface 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 tool unplugged, 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.
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 tool unplugged.
