SELF-FEEDING WOOD CHIPPER

Always wear protective goggles or safety glasses with side shields while chipping to protect your eyes from possible thrown
debris.

Avoid wearing loose clothing or jewelry, which might catch on moving parts or the material fed into the chipper hopper.

We recommend wearing gloves while chipping. Be sure your gloves fit properly and do not have loose cuffs or drawstrings.

Wear shoes with non-slip treads when using your chipper. If you have safety shoes, we recommend wearing them. Do not
use the machine while barefoot or wearing open sandals.

Wear long pants while operating the DR SELF-FEEDING WOOD CHIPPER.

Use ear protectors or ear plugs rated for at least 20 dba to protect your hearing.
The chipper hopper must be securely bolted to your DR SELF-FEEDING WOOD CHIPPER and the blowback shield in place before
using the machine!
Processing Material
The Chipper is designed to accept wood only. The Chipper Knife mounted on a revolving flywheel turns branches fed into the
Chipper Hopper into “chips”. The Chipper can chip branches ranging in size up to 3-3/4" in diameter. Cut your branches into
manageable lengths before feeding them into the Chipper Hopper.

Your DR SELF-FEEDING WOOD CHIPPER can process dry or green wood up to 3-3/4" in diameter.

The Chipper will self-feed the wood once it contacts the knife edge so forcing the branches into the Hopper is not necessary if
the knife is sharp.

Green wood will process quicker and easier than dry wood.

Softwood processes easier than hardwood.

Your operator experience will teach you how different types of wood will chip and how fast you can process them.

When chipping branches, sometimes a tail will develop at the end of a branch. To avoid this, rotate the branch while feeding
it into the Chipper Hopper.

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 2" in diameter. Chip these grouped or bundled
together to provide support for each other. If the material is 2" or larger, feed only one at a time into the Chipper Hopper.

Make sure the DR SELF-FEEDING WOOD CHIPPER finishes processing material in the Hopper before shutting the engine
off.

Do not force material into the Chipper. If the machine does not chip well, the Chipper Knife may need sharpening or
replacement, or the gap between the Knife and the Wear Plate needs adjusting. See “Removing, Replacing and Adjusting the
Chipper Knife and Wear Plate” in Chapter 4.

Extremely hard knots will not process very well. Push any short stubs that have not self-fed through the Chipper, with the next
branch to be chipped.

Cut the material to be chipped into manageable lengths of no more than five or six feet long before chipping them.

Overloading the Chipper Hopper will cause the rotor speed to decrease. If you hear the engine RPM decreasing, stop feeding
material into the Chipper Hopper until the engine has returned to full speed.

Use common sense when using the machine. Learn to recognize the change in sounds when overloaded. Turn off the
engine immediately if the machine becomes jammed to prevent damage to the drive system.

Never throw remaining stubs or knots into the chipper hopper; damage will result.
