Riving Knife; Operation Instructions; Blade Selection; Important - Urrea SM1113 Manual De Usuario

1. Disconect saw from power source.
2. Remove the table insert.
3. Loosen the upper and lower cap screws,
then adjust the 4 set screws in or out until the
alignement is perfectly parallel.
4. Reinstall the table insert.

6. RIVING KNIFE

The key difference between the spreader and
the riving knife is that the riving knife mounts
below the blade's highest point of rotation, as
shown in figure 22.
The riving knife must be kept within the range
shown in figure 23.
WARNING: We only recommend using a 10"
blade for operations that require use of the riv-
ing knife.

OPERATION INSTRUCTIONS

IMPORTANT: MAKE CERTAIN THAT THE SAW
IS DISCONNECTED FROM THE POWER SOURCE.
WARNING: ALWAYS wear eye protection.
Any machine can throw debris into the eyes
during operations, which could cause severe
and permanent eye damage. Everyday eye-
glasses are NOT safety glasses. ALWAYS wear
Safety Goggles (that comply with ANSI stan-
dard Z87.1) when operating power tools.

BLADE SELECTION

NOTE: Choosing the correct blade for the job is
essential for the safe and efficient use of your
table saw. Ignoring this important step could
result in damage to the saw and serious injury
to the operator.
Below are the most common saw blades and
their uses.

1. Rip Blade: Used for cut-
ting with the grain.
Typically, 10" rip blades
have between 18-40 teeth
and large gullets to allow
for large chip removal
(fig.24).
2. Cross-cut Blade: Used
for cutting across
grain. 10" cross-cut blades
have between 60-80 teeth
and a shallow gullet
(fig.25).
3. Combination Blade: Used for cutting with
and across the grain. A compromise between
a rip blade and a cross-cut blade, a 10" combi-
nation blade will typically have between 40-50
teeth.
4. Thin-kerf blade: Most types of saw blades
are available in a thin-kerf style. Designed
primarily to minimize stock waste, thin-kerf
blades are used in conjunction with a blade
stabilizer to reduce blade wobble.
NOTE: Many blade guards/splitters are thicker
than many thin-kerf blades. Make sure that the
stock will pass by the guard/splitter before be-
ginning a cut.
5. Dado Blades: There are two types of dado
blades; stack and wobble. Stack dadoes involve
more setup time, but they provide a superior
finish cut when compared to a wobble dado.
Dado blades require use of accessory dado
table insert.
6. Moulding Heads: A moulding head is a cut-
terhead that attaches to the arbor and holds
individual moulding knives. They are very dan-
gerous and require training beyond the scope
of this manual.
IMPORTANT: Always follow the saw blade
manufacturer's recommendations to assure
safe and efficient operation of your table saw.
CUTS
CROSSCUTTING
Crosscutting means cutting across the grain of
the wood. In wood products without grain (i.e.
MDF, particleboard), crosscutting simply means
cutting across the width of the stock.
Crosscuts are made with the miter gauge,
