The main difference is the Chipper/Shredder has the Shredder compartment.

USING THE SHREDDER HOPPER
•The shredder hopper is located on the top of the unit and
is the opening into which all materials to be shredded
should be fed. Most organic materials can be shredded.
A flex guard, or blowback shield is secured to the hopper. Material must be pushed past this flap using a wooden stick in order to enter the main chipper-shredder chamber where revolving steel hammers do the shredding. The blow back shield is an important feature. It prevents kickback of materials! Do not use your machine unless the blow back shield is securely fastened in place.
•Due to the wide variety of materials that can be shredded,
and their very different physical characteristics, only feed limited quantities of any material into the hopper at first. The amount and length of material can be increased if you find that the material is being processed without any difficulty. Your judgment and operator experience is very important. Be sure not to overload the machine by feeding too much material into the hopper at one time. If you hear the RPM’s decreasing, stop feeding material into the machine at once. Do not resume feeding the machine until it has returned to full speed.
•The maximum diameter of material that can be shredded is
1 ½”. Any larger material should be fed through the chipper-hopper. Material larger than 1 ½” can cause serious damage to any of the internal parts of the chipper-shredder chamber. The unit should be inspected after every use for bent hammers, missing spacers, damage to the screen or any other obvious problems. If damage occurs, the rotor assembly can become unbalanced causing excessive vibration. If used in this state, damage can occur. Do not use the machine if vibration is present. Vibration is generally a warning sign of trouble.
•Several small branches can be fed into the shredder-hopper at once providing their combined diameter is less
than 1 1/2”. Branches longer than three feet should be
cut to make them more manageable. Green materials
should be allowed to dry, or processed in small batches with dry materials to avoid winding around the rotor assembly.
