Adjusting The Riving Knife - Makita 2704N Manual De Instrucciones

3. Assemble the inner flange, ring, saw blade, outer
flange and hex nut onto the arbor, making sure that the
teeth of the blade are pointing down at the front of the
table. Always install the hex nut with its recessed side
facing the outer flange.

4. Outer flange 5. Hex nut
CAUTION:
Be sure that the saw blade is
installed so that the teeth are aligned in the cut-
ting (turning) direction.
CAUTION:
Check the arbor hole diameter of
the saw blade before installing the saw blade.
Always use the correct ring for the arbor hole of
the saw blade you intend to use. The size of the
supplied ring(s) varies depending on the country.
• For tool for a 30 mm hole-diameter saw blade,
the ring 30 mm in outer diameter is provided.
• For tool for a 25.4 mm and 25 mm hole-diameter
saw blade, the silver and black rings are pro-
vided. Use the silver ring for 25.4 mm hole-di-
ameter saw blade and the black ring for 25 mm
hole-diameter saw blade.
4. To secure the saw blade in place, hold the outer
flange with the offset wrench, then tighten the hex nut
clockwise with the wrench. BE SURE TO TIGHTEN
THE HEX NUT SECURELY.

CAUTION:
Keep the flange surface clean of dirt or
other adhering matter; it could cause blade slippage.
CAUTION:
Be sure to hold the hex nut care-
fully with the wrench. If your grip should slip, the
wrench may come off the hex nut, and your hand
could strike the sharp blade edges.
5. Attach the table insert in place with the screw.

Adjusting the riving knife

CAUTION:
If the saw blade and riving knife
are not aligned properly, a dangerous pinching
condition may result during operation. Make sure
they are properly aligned. You could suffer serious
personal injury while using the tool without a properly
aligned riving knife.
CAUTION:
NEVER make any adjustments
while tool is running. Disconnect the tool before
making any adjustments.
CAUTION:
Don't remove the riving knife.
► Fig.24: 1. Blade guard 2. Riving knife 3. Screw
The riving knife position is factory-adjusted so that
the saw blade and riving knife will be in a straight line.
However, you need to adjust it if the saw blade and
riving knife are not in a straight line.
Loosen the screw on the table insert and remove it from the
main table. Loosen the hex bolts (B) and adjust the blade
guard mounting portion (stay) so that the riving knife is
aligned directly behind the saw blade. Then tighten the hex
bolts (B) to secure the stay and put the table insert in place.
► Fig.25: 1. Blade 2. These two clearances should be equal.

There must be a clearance of about 4 - 5 mm between
the riving knife and the blade teeth. Loosen the hex
bolts (A), adjust the riving knife accordingly and tighten
the hex bolts (A) securely. Attach the table insert on the
table with the screw, then check to see that the blade
guard works smoothly before cutting.

Installing and adjusting rip fence
► Fig.27: 1. Hook 2. Knob 3. Guide rail
1.
Fit the hook on the tip of the rip fence into the far
guide rail on the table or sub table (R) and install and
push the rip fence forward so that the fence holder
engages with the nearmost guide rail.
2. To slide the rip fence on the guide rail sideways,
return the knob on the fence holder fully without pulling
the lever on the knob.
To secure the rip fence, pivot fully the knob on the fence
holder.
3. To remove the rip fence, pull the lever on the knob
and pivot the knob fully forward while pulling the lever.
To check if the rip fence is parallel with the saw blade,
secure the rip fence 2 - 3 mm from the saw blade. Raise
the blade up to maximum elevation. Mark one of the
blade teeth with a crayon. Measure the distance (A)
and (B) between the rip fence and saw blade. Take both
measurements using the tooth marked with the crayon.
These two measurements should be identical. If the
rip fence is not parallel with the saw blade, proceed as
follows:
► Fig.28: 1. Scale
1. Position the rip fence in the sliding position.
2. Loosen the two hex bolts on the rip fence with the
hex wrench provided.
► Fig.29: 1. Hex bolts
3. Adjust the rip fence until it becomes parallel with
the saw blade.
4. Pivot down the knob on the rip fence toward the
operator.
5. Tighten the two hex bolts on the rip fence.
► Fig.30
CAUTION:
Be sure to adjust the rip fence so
that it is parallel with the saw blade, or a danger-
ous kickback condition may occur.
When the rip fence cannot be secured solidly, adjust it
according to the following procedure.
1. Set the rip fence on the table and then pivot the
knob on the half way of its travel (moving position).
Tighten the screw (A) until the rip fence is immobilized.
Then loosen a 1/4 to 1/2 turn.
