The Hammers within the Shredding Chamber can tug suddenly at material fed into the Shredder Hopper. Do not hold on tightly
to branches and vines, and do not 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.
Using the Shredder Hopper
The Shredder Hopper is located on the top of the DR CHIPPER/SHREDDER and is the opening into which all materials to be
shredded should be fed. You can shred most organic materials. A flex guard, or blowback shield is attached to the Hopper. You
must push material past this flap using a wooden stick in order to enter the main Shredding Chamber where revolving steel
Hammers do the shredding.
 Due to the wide variety of materials that you can shred, and their very different physical characteristics, only feed limited
quantities of any material into the Shredder Hopper at first. Increase the amount and length of material if you find that the
material is processing 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 speed of the Engine decreasing, stop
feeding material into the machine at once. Do not resume feeding the machine until the Engine has returned to full speed.
 The maximum diameter of material that you can shred is 3/8". Feed any larger material through the Chipper Hopper. Material
larger than 3/8" can cause serious damage to any of the internal parts of the Shredding Chamber. Inspect the DR
CHIPPER/SHREDDER after every use for bent Hammers, missing Spacers, clogging, or 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
condition, damage can occur. Do not use the machine if vibration is present. Vibration is generally a warning sign of trouble.
 You can feed several small branches into the Shredder Hopper at once providing their combined diameter is less than 3/8".
Cut branches longer than three (3) feet to make them more manageable. Allow green materials to dry, or process in small
batches with dry materials to avoid winding around the Rotor Assembly.
 Wet materials will clog the machine easily. If clogging occurs, stop the Engine; remove the screen and process material without
it. Processing in this way will reduce the amount of reduction, but will reduce clogging.
MATERIALS BEST SUITED FOR SHREDDING
Leaves Flowers Corn Stalks Roots
Soil Palm frond tops Grass clippings Garden debris
Potato vines Straw and Hay Hedge clippings Tomato vines
Manure Kitchen Waste Small branches
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.
