• When chipping branches, sometimes a tail will be left at the end of a branch. To avoid this,

rotate the branch as it is fed into the chute.

• Rotating the branch as you feed it into the machine will improve chipping performance.
• Optional screens are available for both greater and less reduction of the material being

processed through the shredder hopper.



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 blowback shield is an important feature. It
prevents kickback of materials! Do not use your machine unless the blowback 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.


MATERIALS BEST SUITED FOR SHREDDING

Leaves

Roots

Grass clippings

Straw

Hay

Small branches

Flowers

Soil

Garden debris

Hedge clippings

Kitchen Waste

Manure

Corn Stalks

Palm frond tops

Potato vines

Tomato vines

Paper




NOTE - The hammers within the chipper-shredder chamber can tug suddenly at material

being fed into the shredder-hopper. Do not hold on tightly to branches and vines, and don’t

feed material straight down into the hopper with your arm pointing downward toward the

opening. Instead, keep your arms parallel to the ground and several inches above the top

edge of the hopper.
