The Hammers within the Shredding Chamber can tug suddenly at material fed into the Shredder Hopper. Wear Gloves and 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 Chipper Chute
The Chipper Chute is designed to chip thicker materials that the Shredder Hopper isn’t designed to handle. The revolving Chipper
Knife mounted on a Flywheel turns branches fed into the Chute into “chips”. The Chipper can chip twigs and branches ranging in
size from 1/2" to 4" in diameter. Cut your materials into manageable lengths
before
feeding them into the Chipper Chute.

Hold onto and slowly feed material into the Chipper Chute while paying attention to the engine speed. Do not force material or
allow material to be pulled too quickly into the Chipper.

Larger diameter hardwood or extremely hard knots may not process as well as other materials. Discard larger diameter or
harder branch stubs before they become too short to control their feed rate.

Overloading the Chipper Chute will cause the Engine speed to decrease. If the Engine bogs down, stop feeding material into
the Chipper Chute and wait until the Engine returns to full speed before continuing.

Your DR 11.5 CHIPPER SHREDDER can process dry or green material. Green material will process quicker and easier than dry
material. Soft wood processes easier than hard wood.

If the machine does not chip well, the Chipper Knife may need sharpening or may need to be replaced.

It is best to trim off any side twigs from the main branch that you are chipping.

When chipping branches, sometimes a tail will remain at the end of a branch. To avoid this, rotate the branch while feeding it
into the Chipper Chute. Rotating the branch as you feed it into the machine will improve chipping performance.

Use caution with small diameter green saplings and branches less than 1" in diameter. Chip these grouped or bundled
together to provide support for each other. If the material is 1" or larger, feed only one at a time into the Chipper Chute.

NEVER allow processed material to build up within 3" of the Discharge opening. Move the DR 11.5 CHIPPER SHREDDER or
the pile as needed. Failure to do so could result in unnecessary jamming of the machine.

To move a pile of processed material, first shut off the Engine, and use a spade, rake, or long handle tool; NEVER use your
hands or feet!

Make sure the DR 11.5 CHIPPER SHREDDER finishes processing and discharging material before shutting the Engine off.
Using the Shredder Hopper
The Shredder Hopper can process hard wood branches up to 3/4" in diameter and softer organic material up to 4-1/2" in
diameter. You can shred most organic materials. A Guard (flap) is attached to the Hopper. You must push material past this
flap (using a branch if necessary) 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 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.

You can feed several small branches into the Shredder Hopper at once providing their combined diameter is less than 3/4".
Cut branches so they are shorter than 3 feet long to make them more manageable.

Allow green materials to dry before processing or alternate processing and discharging green/wet materials with dry materials
to avoid clogging. If wet materials begin to clog, shred a stick to clear the material through. The shredding capacity is 3/4"
hard woody material. For clearing a clog, you can intermittently shred a larger stick up to 1" diameter.
