Riving Knife Mounting Block - Grizzly G0853 Owner's Manual

Riving Knife
Mounting Block
The riving knife must be aligned with the blade
when installed. If the riving knife is not aligned
with the blade, then the workpiece will be forced
sideways during the cut, which will increase the
risk of kickback.
The riving knife mounts to a block that can be
repositioned to correctly align the riving knife with
the blade. The mounting block adjusts by turning
the set screws in each corner of the block. Figure
187 shows the set screws associated with control-
ling the mounting block position. Have patience
when adjusting the mounting block, because it
requires trial-and-error to perform with accuracy.

To adjust riving knife mount block:
1. Raise blade guard and move it away from
blade, then adjust blade tilt to 0° and raise
blade all the way up.
2.
DISCONNECT MACHINE FROM POWER!
3.
Move sliding table all the way backward to
expose blade cover, then lock it in place.
4. Use blade locks to open cover (see Figure
98 on Page 55) and gain access to riving
knife mounting block.
5.
Loosen hex nut that secures riving knife to
mounting block, and remove riving knife.
6.
Adjust each pair of set screws that controls
the direction required to move mounting
block so riving knife can be aligned with
blade. Make sure to move both set screws in
even increments.
7.
Re-install riving knife and check alignment
with blade. Repeat Step 6 as necessary until
riving knife is properly aligned with blade.
Note: If you discover that riving knife is bent
and cannot be properly aligned with the
blade, it is possible to bend it into alignment,
but make sure that the final result is pre-
cisely aligned so the risk of kickback is not
increased. If the riving knife is bent, and you
cannot easily bend it back into alignment, we
recommend replacing it with a new one.
8. Properly re-install riving knife as described on
Page 49, close blade cover, properly reposi-
tion blade guard, and move sliding table back
to center position.
