Discharge Grates

charge grate has 1½” diameter holes.
• Installing a discharge grate with small-
er diameter holes can increase ne-
ness of the shredded material.
• Discharge grates with ½” and ¾” diam-
eter holes are available for the Chip
per/Shredder.
• A discharge grate with parallel bars is
available for shredding leaves or green
material.
To change discharge grates:
1. Remove the rear door hinge pin and
remove the rear safety door.
2. Remove the 6- 3/8” x 1” bolts holding the
grate in place. Remove the grate.
3. Install new grate. Make sure to install the
rounded edge of the grate to the bottom.
4. Reinstall bolts and rear safety door.

inspect the machine until you see
that the shafts have stopped turn-
ing and that there is no noise com-
ing from the machine.
• Never operate Chipper/Shredder
