3.5 Changing Discharge Screens
Optional discharge screens with different hole sizes
can be purchased and used in your chipper/shredder.
To change the screen proceed as follows:
1. Stop engine, disengage rotor, and allow machine to
come to a complete stop. Remove spark plug wire
from spark plug (engine models).
2. Remove the 5/16 inch bolt in the bottom center that
holds the discharge screen in place. Pull the screen
out of the machine and set aside.
3. Clean any trash or debris out of the screen area.
4. Place optional screen in machine. Hook top lip of
screen into slot and rotate screen downward to align
hole in screen with hole in machine. Place bolt
through machine and screen, attach nut and tighten.
3.6 Trailer Service Tips

1. Check wheel bolt torque every 10 hours of towing
use.
2. Check air pressure in tires every 10 hours of towing.
Tires are rated at 60 PSI maximum.
3. Check and repack wheel bearings with grease every
year.
4. When towing, use a 2" trailer ball and always
connect the safety chains. Make sure that the trailer

the bearing by over greasing.
