Protecting Yourself and Those Around You

This is a high-powered machine, with moving parts operating with high energy. You must operate the machine safely. Unsafe operation can create a number of hazards for you, as well as anyone else in the nearby area. This machine can crush, grind, cut, and sever parts of your body if they enter the inlet or discharge area of your CHIPPER/SHREDDER. Always take the following precautions when using this machine:

 Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and

themselves.

 Always wear protective goggles or safety glasses with side shields while using the CHIPPER/SHREDDER to protect your eyes

from possible thrown debris.

 Avoid wearing loose clothing or jewelry, which can catch on moving parts or the material fed into the CHIPPER/SHREDDER.  We recommend wearing gloves while using the CHIPPER/SHREDDER. Be sure your gloves fit properly and do not have loose

cuffs or drawstrings.

 Wear shoes with non-slip treads when using your CHIPPER/SHREDDER. 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 CHIPPER/SHREDDER.  Use ear protectors or earplugs rated for at least 20 dba to protect your hearing.  Keep bystanders at least 100 feet away from your work area. Stop the engine when another person or pet approaches.

Safety for Children and Pets

Tragic accidents can occur if the operator is not alert to the presence of children and pets. Children are often attracted to the machine and the chipping/shredding activity. these precautions:

Never

assume that children will remain where you last saw them. Always follow

 Keep children and pets at least 100 feet from the working area and ensure they are under the watchful care of a responsible

adult.

 Be alert and turn the machine off if children or pets enter the work area.  Never allow children to operate the CHIPPER/SHREDDER.

CHIPPER/SHREDDER

Safety with Gasoline - Powered Machines

Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or explosion. Never overlook the hazards of gasoline. Always follow these precautions:

 Never run the Engine in an enclosed area or without proper ventilation as the exhaust from the Engine contains carbon

monoxide, which is an odorless, tasteless, and deadly poisonous gas.

 Store all fuel and oil in containers specifically designed and approved for this purpose and keep away from heat and open

flame, and out of the reach of children.

 Replace rubber Fuel Lines and Grommets when worn or damaged and after 5 years of use.  Fill the Gasoline Tank outdoors with the Engine off and allow the Engine to cool completely. Don't handle gasoline if you or

anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the Fuel Tank Cap and Fuel Container Cap securely.

 If you spill gasoline, do not attempt to start the Engine. Move the machine away from the area of the spill and avoid creating

any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly dispose of the waste.

 Allow the Engine to cool completely before storing in any enclosure. Never store a machine that has gas in the tank, or a Fuel

Container, near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.

 Never make adjustments or repairs with the Engine running. Shut down the Engine, disconnect the Spark Plug wire, keeping

it away from the Spark Plug to prevent accidental starting, wait 5 minutes before making adjustments or repairs.

 Never tamper with the Engine’s Governor setting. The Governor controls the maximum safe operation speed and protects

the Engine. Over-speeding the Engine is dangerous and will cause damage to the Engine and to the other moving parts of the machine. If required, see your authorized dealer for Engine governor adjustments.

 Keep combustible substances away from the Engine when it is hot.  Never cover the machine while the Muffler is still hot.  Do not operate the Engine with the Air Cleaner or the Carburetor Air Intake Cover removed. Removal of such parts could

create a fire hazard. Do not use flammable solutions to clean the Air Filter.

 The Muffler and Engine become very hot and can cause a severe burn; do not touch.

General Safety

Operating this CHIPPER/SHREDDER safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can create a number of hazards for you. Always take the following precautions when operating this machine:

 Your CHIPPER/SHREDDER is a powerful tool, not a plaything. Exercise extreme caution at all times. The machine is

designed to chip wood and shred most organic materials. Do not use it for any other purpose.

 Thoroughly inspect the area in which you will be working and remove all foreign objects. Look for rope, wire, etc., and remove

these objects before chipping/shredding. Inserting these objects into the CHIPPER/SHREDDER Hopper could damage the machine and/or cause injury.

 Know how to stop the CHIPPER/SHREDDER quickly; see “Stopping the Engine” in Chapter 3.  Never operate your unit on a slippery, wet, muddy, or icy surface. Exercise caution to avoid slipping or falling.  See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by DR

Power Equipment.

 Never use the machine without ensuring that all guards and shields are in place.  Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the CHIPPER/SHREDDER.

This includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will void your warranty.

 Never use the machine with the Hopper(s) or Discharge Chute removed.

General Safety (continued)

 Never place any part of your body in the CHIPPER/SHREDDER Hopper(s), discharge opening, or near any moving part while

the machine is running. Keep the area of discharge clear of anything that will obstruct a clear discharge. Wind can also change discharge direction, so be aware. If it becomes necessary to push material into the CHIPPER/SHREDDER Hopper(s), use a small diameter stick, NOT WITH YOUR HANDS.

 Keep your face and body back from the CHIPPER/SHREDDER Hopper(s) to avoid accidental bounce back of any material.  Do not allow an accumulation of processed material to build up in the discharge area as this will prevent proper discharge

and can result in kickback from the CHIPPER/SHREDDER Hopper(s).

 Allow only one person to operate the CHIPPER/SHREDDER at any time.  Always operate the machine from the Operator Zone (see Figure 10

of the machine when the Engine is running or the Rotor is turning.

 If the machine should start making an unusual noise or vibration, shut down the Engine, disconnect the Spark Plug Wire,

keeping it away from the Spark Plug to prevent accidental starting, wait 5 minutes, then inspect for damage. Vibration is generally a warning of trouble. Check for damaged parts and clean, repair, and/or replace as necessary.

 Never tamper with safety devices. Check their proper operation regularly.  Never try to pick up, move, or transport the machine while the Engine is running or the Rotor is turning.  Before performing any maintenance or inspection procedure on the CHIPPER/SHREDDER, shut the Engine OFF, remove the

Spark Plug Wire, and keep it away from the Spark Plug.

 Never allow people who do not understand and/or have not read this Safety and Operating Instructions Manual to use the

CHIPPER/SHREDDER. Allow only responsible individuals who are familiar with these rules of safe operation to use your machine.

 Never overload or attempt to Chip or Shred material beyond the manufacturer’s recommendation. Personal injury or damage

to the machine could result.

 While using the CHIPPER/SHREDDER, don't hurry or take things for granted. When in doubt about the equipment or your

surroundings, stop the machine and take the time to look things over.

 Never operate the machine when under the influence of alcohol, drugs, or medication.  Use the machine only in daylight.  Stay alert for hidden hazards or traffic.  Keep all nuts and bolts tight and keep the equipment in good operating condition.

turn, STOP the Engine and clean out the Chipper/Shredder Hopper(s) as instructed on page 16.

 ALWAYS operate the DR CHIPPER/SHREDDER from the Operator Zones

(Figure 8).

 When viewed from the Chipper Hopper side the Rotor turns in a clockwise

direction.

 NEVER assume you know where the Chipper Knife is. You do not know where

it is.

 ALWAYS stop the Engine when leaving the Operating Zone or when moving

Processing Material

Read and understand the warnings listed in “Chapter 1 General Safety Rules” before operating this CHIPPER/SHREDDER.

 Your DR 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.  Your operator experience will teach you how different materials chip/shred and how fast you can process different materials.  Most materials process well with the standard screen provided with the DR CHIPPER/SHREDDER.  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 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 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 Hopper.

 Make sure the DR CHIPPER/SHREDDER finishes processing material in the Hopper(s) before shutting the Engine off.

Using the Chipper Hopper

The Chipper Hopper is mounted on the side of the machine and is designed to chip the larger, heavier materials that the Shredder Hopper isn’t designed to handle. The revolving Chipper Knife mounted on a Rotor turns branches fed into the Hopper into “chips”. The Chipper can chip twigs and branches ranging in size from 1" to 2-1/2" in diameter. Cut your materials into manageable lengths of no more than five or six feet long

before feeding them into the Chipper Hopper.

The Chipper Hopper must be securely bolted to the side of your DR CHIPPER/SHREDDER before using the machine!

 Feed the branch into Chipper Hopper keeping the branch at the same angle as the Chipper Hopper.  As the branch becomes short and is at the outside edge of the Chipper Hopper, finish processing it by pushing it in with the

next branch.



Do not force material into the Chipper. If the machine does not chip well, the Chipper Knife may need sharpening or to be

replaced.

 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.

Never throw remaining stubs or knots into the Shredder Hopper; damage will result.

 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.

 NEVER allow processed material to build up within 3" of the Discharge opening. Move the DR 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

hands or feet!

If you jam the machine and do not stop the Engine, it can damage the machine. This damage can be costly and not covered under warranty. See “To Free a Jammed Flywheel” on page 16.

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.

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 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 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.

Knife Sharpening

 You should never attempt to sharpen the Chipper Knife freehand; take the Knife to a machine shop for proper sharpening.  It is extremely important to consistently maintain the 45-degree angle for proper performance.  Excessive heat generated during the sharpening process will damage Knives and weaken the metal.  How many times a Knife can be sharpened is determined by how much material needs to be taken off to sharpen or to

compensate for dents or gouges.

 A new Chipper Knife has a 5/16" measurement between the short side bevel edge and the Knife mounting holes (Figure 19).

 The knife should never be sharpened to the extent that more than 3/32" is taken off this measurement.  Once this measurement is below 7/32" (Figure 20), or if you are unable to remove dents or gouges with these guidelines,

replace the Knife.

Removing and Replacing the Clutch

The design of the Clutch on your machine is for rugged, dependable service, however, it is important to understand the limitations of a Clutch. The Clutch design is to provide load free starting of the Engine, and slippage under excessive overloading of the driven application. These features help protect the Engine from damages such as broken crankshafts and starters. The Clutch on this machine is permanently lubricated and does not require oil or grease. The Drum, Shoes, and Springs in the Clutch are normal wear items. If, after long periods of use, the Drum wobbles excessively, or if you notice decreased performance of the Clutch, replace the Clutch.

The Clutch obtains its power from the Engine RPM. The lower the engagement speed, and the higher the maintained Engine speed, the more torque the Clutch can transfer to the driven unit. NEVER operate the DR CHIPPER/SHREDDER Engine at less

than full RPM.

Tools and Supplies Needed:

 Two 1/2" Wrenches  9/16" Wrench  Anti-seize compound

1. Remove the Belt as described in the “Replacing The Belt” section.

2. Remove the Clutch from the Engine Crankshaft by removing the Clutch Bolt

and Washer and then slide the Clutch Assembly from the Crankshaft (Figure

28) (any Spacers remain on the Crankshaft).

Tip: Hold the Hub with Vise Grips while loosening the Clutch Bolt.

3. Remove the Key from the Keyway in the Engine Crankshaft and set it aside.

Figure 28

4. Clean the Engine Crankshaft and remove any burrs, then apply anti-seize

compound to the Crankshaft.

5. Install the Key in the Keyway of the Engine Crankshaft, align the Key with the

slot in the new Clutch Hub, and then slide the new Clutch Assembly onto the Crankshaft followed by the Washer and Clutch Bolt. Tighten the Bolt securely.

6. Reinstall the Drive Belt and set the Belt tension as described in the

“Checking and Setting Belt Tension” section.

7. Reinstall the Belt Guard and Baffle Plate.

Daily Checklist for the DR CHIPPER/SHREDDER

To help maintain your DR CHIPPER/SHREDDER for optimum performance, we recommend you follow this checklist each time you use your Chipper/Shredder.

Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all parts to cool. Disconnect the Spark Plug Wire, keeping it away from the Spark Plug.

[ ] Check the Engine oil and Fuel Tank level. [ ] Check that Engine is clean of debris. [ ] Inspect the Chipper/Hopper(s) for accumulated debris. [ ] Check the general condition of the Chipper/Shredder, e.g.; nuts, bolts, welds, etc. [ ] Check Belt for wear and/or stretching. [ ] Check Tire Pressure and wear. [ ] Check the Chipper Knife for tightness, nicks and wear. [ ] Check the Debris Guard for wear and damage. [ ] Remove any debris wrapped around the Hammer(s) Rotor.

End of Season and Storage

Before performing any maintenance procedure or inspection, stop the Engine, wait five (5) minutes to allow all parts to cool. Disconnect the Spark Plug Wire, keeping it away from the Spark Plug.

 Change the Engine oil.  Clean or replace the Air Filter.  Check the Chipper Knife and Hammers for nicks and wear.  Remove any debris wrapped around the Hammer Rotor.  If your DR CHIPPER/SHREDDER will be idle for more than 30 days, we recommend using a gas stabilizer. This will prevent

sediment from gumming up the Carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the tank. Completely fill the tank with fresh, unleaded gas and add the appropriate amount of stabilizer or gasoline additive. Run the Engine for a short time to allow the additive to circulate. Close the Fuel Shut-Off Valve to prevent carburetor overflow and leakage.

 Clean the exterior of the unit to remove all dirt, grease, and any other foreign material. To prevent rust, touch up painted

surfaces that have been scratched or chipped.

 Be sure all nuts, bolts, and screws are securely fastened.  Inspect moving parts and the Drive Belt for damage and wear; replace if necessary.  Remove the Spark Plug and pour about 1 ounce of motor oil into the Cylinder hole. Replace the Plug and crank the Engine

over a couple of times using the Pull Cord. This will coat the piston and seat the valves to prevent moisture buildup.

 If possible, store the Chipper/Shredder in a dry, protected place. If it is necessary to store the machine outside, after the

DR CHIPPER/SHREDDER has cooled, cover the machine with a suitable protective cover that does not retain moisture. Do not use plastic as this material cannot breathe; it also allows condensation to form, which will cause your machine to rust.
