Guard Covers
The G0853 features two dust hood assemblies
for either straight cuts or angled cuts. Use the
flat blade cover when performing straight (90°)
cuts or the wide (bubble) cover for angled cuts.
To change between covers, loosen the lock knob
(see
Figure 80), pull the guard assembly straight
out, install the other cover, and re-tighten the lock
knob.

Riving Knife
The riving knife (see
Figure 81) is a metal
plate that prevents the freshly cut pieces of the
workpiece from pinching the backside of the blade
and causing kickback. It also acts as a barrier
behind the blade to shield hands from being pulled
into the blade if kickback occurs and the operator
is reaching behind the blade. (Reaching behind
the blade is a major safety risk and should never
be done.) Use the riving knife for all operations.

The riving knife must be correctly installed, adjust-
ed, and aligned in order to provide the maximum
safety benefit.
The riving knife attaches to the mounting block as
shown in
Figure 82. Always firmly tighten the hex
nut when securing the riving knife in place.

Figure 83. Height difference between riving knife
and blade.
Secure the riving knife so the top is 1–5mm below
the top level of the blade, as shown in
Figure 83.
For riving knife to work safely, it MUST be
aligned with and correctly adjusted to blade.
The height difference between the riving knife and
the blade allows the workpiece to pass over the
blade during non-through cuts (those in which the
blade does not cut all the way through the thick-
ness of the workpiece).
