CLEARING THE MACHINE OF A PLUGGED ROTOR
The most common reason to remove
the discharge screen is for sharpening
the chipper blades. Removal is also
necessary for optional discharge
screens.
A standard coarse (1-1/2 inch diam-
eter hole) discharge screen is supplied
with your machine. Optional discharge
screens may be purchased for your
machine which include:
• Fine (3/8 inch diameter holes)
• Medium (3/4 inch diameter holes)
• Coarse (1-1/2 inch diameter holes
shipped standard)
• Wet Debris screen (1-1/2 inch di-
ameter slots)
Consult your local Bear Cat Dealer for
optional equipment.
To remove change the discharge
screen follow this procedure.
1. Lift discharge door to gain access
to the discharge screen.
2. Using a 1/2” wrench, remove the
5/16” bolt and nut securing the dis-
charge screen to the chipper shred-
der frame.
3. Pull discharge screen out from the
bottom and rotate the top down.
4. Clean any trash or debris out from
the screen area.
To sharpen or replace the chipper
blades, see the Maintenance section
of this manual.
5. Select replacement screen option
and insert the top of the screen into
the slot in the chipper body and push
the bottom of the screen inward so
bolt holes align.

upward through the frame and
screen, attach nut and tighten to
