Operating instructions

• Your DR RAPID-FEED CHIPPER can process dry or green wood up to 4.5" 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 RAPID-FEED 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 5.

• 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.

THE CHIPPER HOPPER MUST BE SECURELY BOLTED TO YOUR DR RAPID-FEED CHIPPER AND THE

BLOWBACK SHIELD IN PLACE BEFORE USING THE MACHINE!

NEVER THROW REMAINING STUBS OR KNOTS INTO THE CHIPPER HOPPER

;

DAMAGE WILL RESULT.
