Changing The Blade
To prevent personal injury, always discon-
nect plug from power source before chang-
i
ng blades.
Using the Correct Blade
IMPORTANT:
The saw blade provided on this tool has a
carbide-tipped kerf width of .128” and a plate (body) thickness
t
hat is .086” thick. When looking for a replacement blade, select
one with dimensions close to the original blade. This information
may not be printed on the blades packaging. If not, check the
m
anufacturers catalog or website. Bosch offers an extensive line
of Premium-Quality Professional Saw Blades that match the
requirements for this tool. You must select a blade with a kerf
w
idth of .092” or more and a plate (body) thickness .088” or less
(Fig. 10).
To reduce the risk of injury, do not use extra
thin kerf saw blades.
The kerf of the blade
must be wider than .092”. Extra thin kerf saw blades (less than
.092”) may cause the work piece to bind against the riving knife
during cutting. It is recommended that the kerf of the
replacement blade used on this saw be .092” or more.
To reduce the risk of injury, do not use saw
blades made with a thick body plate.
If the
replacement saw blade's plate thickness is greater than .088”,
the riving knife would not properly serve as an aid to reduce
kickback. The replacement blade's plate thickness must be less
than .088”.
To reduce the risk of injury, do not use blade
“dampeners,” “stabilizers,” or “stiffening
collars” on both sides of a replacement blade.
These are
metal plates positioned against the sides of the blade to reduce
deflection that may occur when using thin saw blades. Use of
these devices on both sides will prevent the blade from being
properly aligned with the riving knife, which may bind the work
piece during cutting. One “stabilizer” plate may be placed only
against the outside of a thin replacement blade. These plates are
not required with the supplied Bosch blade.
