Protecting Yourself and Those Around You

This is a high-powered machine, with moving parts operating with high energy at high speeds. You must use proper clothing and safety gear when operating this machine to prevent or minimize the risk of severe injury. This machine can cut, and sever parts of your body if they become in contact with the moving chipper blades. Always take the following precautions when operating this machine:

 Always wear protective goggles or safety glasses with side shields while operating either your tractor lawn deck, vacuum

system, chipper or performing an adjustment on your DR Leaf and Lawn Vacuum to protect your eyes from possible foreign objects thrown from the machine.

 Avoid wearing loose clothing or jewelry, which can catch on the machine’s moving parts.  We recommend wearing gloves while using the DR Leaf and Lawn Vacuum. Be sure your gloves fit properly and do not have

loose cuffs or drawstrings.

 Wear shoes with non-slip treads when using your DR Leaf and Lawn Vacuum. 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 Leaf and Lawn Vacuum.  Use ear protectors or earplugs rated for at least 20 dba to protect your hearing.

Safety for Children and Pets

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

Never

assume that children or pets will remain where you last saw them.

 Keep children and pets at least 50 feet from the working area and ensure they are under the watchful care of a responsible

adult.

 Be alert and always turn off the lawn tractor engine and the DR Leaf and Lawn Vacuum engine if children or pets enter the

work area.

 Before and while moving backwards, look behind, and

collector box.

down

for small children and pets. You cannot see directly behind the

 Never allow children to operate the Lawn Tractor or Vacuum/Chipper.  Never allow children or pets to play in the collector. If they become trapped in the enclosure they may be exposed to

temperatures similar to leaving a child or pet in a car with the windows closed on a sunny day.

 Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

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.

4 DR

LEAF and LAWN VACUUM

 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 and empty the collector box before storing the DR Leaf and Lawn Vacuum in any

enclosure. Remember, decomposing material can generate heat and start a fire. Never store the machine with 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 your hands and combustible substances away from the engine when it is hot and clean the engine area after each use.  To reduce fire hazard, keep the engine cooling fins and muffler area free of debris build-up such as leaves, grass, oil, grease or

any other combustible material.

 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, except for adjustment. 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.  The exhaust area on the engine becomes very hot with use. Allow the engine to cool before doing maintenance or making

adjustments.

Slope Operation

Slopes are a major factor related to tip over accidents, which can result in severe injury. All slopes require caution. If you feel uneasy on a slope, do not vacuum it. Always take the following precautions when using this machine on slopes: ALWAYS:

 Vacuum up and down the face of slopes, never across. Exercise extreme caution when changing direction on slopes.  Remove objects such as stones, glass and metal objects such as cans.  Watch out for holes, ruts, or bumps. tall grass can hide obstacles.

NEVER:

 Never vacuum near drop-offs, ditches, or embankments. Your tractor and the vacuum may tip over.  Never vacuum on slopes greater than 15 degrees or any excessively steep slopes.  Never vacuum on wet slopes. Reduced traction could result in slipping and a possible roll over.

General Safety

This is a high-powered machine, with moving parts operating with high energy at high speeds. 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. Always take the following precautions when using this machine:

 Never allow people who are unfamiliar with these instructions to use the DR Leaf and Lawn Vacuum.  To be safe, do not operate the machine near small children or pets, and never allow children to operate the vacuum. Stop the

vacuum engine and tractor engine when another person or pet approaches.

 Never allow people or pets to ride in the collector box or on the frame.

 Check behind your DR Leaf and Lawn Vacuum before backing up. You cannot see directly behind the collector box.  Never attempt to dump a load while the lawn tractor deck is engaged or the DR Leaf and Lawn Vacuum engine is running.  Do not operate in sandy areas where you will vacuum large quantities of sand. Sand will erode the vacuum housing. Check

for pin holes after each use and replace the housing when pin holes develop.

 Do not attempt to open the collector box when your DR Leaf and Lawn Vacuum engine or your lawn deck engine is operating.

Debris may exit at high velocity as you begin to remove the collector back panel.

 Never operate the machine on slopes greater than 15 degrees.  Never tow the DR Leaf and Lawn Vacuum faster than 8 mph.  Keep your hands out of the chipper hopper and vacuum inlets while the lawn tractor and the DR Leaf and Lawn Vacuum

engines are running. If it becomes necessary to push material into the hopper, use a small diameter stick.

 Always shut off the lawn tractor engine and the DR Leaf and Lawn Vacuum engine, allow the engine to cool five (5) minutes

and disconnect the spark plug wire before attempting to clear any obstructions in the hoses or chipper hopper.

 Use the DR Leaf and Lawn Vacuum only in daylight.  Never straddle or reach over the engine area at any time.  Use only your hands to operate the DR Leaf and Lawn Vacuum engine controls.  Do not, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR Leaf and Lawn

Vacuum. Modifications to your machine could cause personal injuries and will void your warranty.

 Do not alter or tamper with safety devices or shields. Make sure they are in their proper position.  While using the DR Leaf and Lawn Vacuum, do not hurry or take things for granted.  Never leave the DR Leaf and Lawn Vacuum unattended with its engine running.  Do not operate the machine when under the influence of alcohol, drugs, or medication.

The DR Leaf and Lawn Vacuum must be operated safely to prevent or minimize the risk of minor or moderate injury. Unsafe operation can create a number of hazards for you. Always take the following precautions when operating this machine:

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

themselves.

 Remove side branches before chipping to prevent jamming the material in the chipper hopper.  Do not attempt to chip wood larger than specified in this manual.  Never use the DR Leaf and Lawn Vacuum to vacuum anything but yard waste, such as leaves, grass, small twigs and pine

cones.

 If the machine starts to make an unusual noise or vibration, immediately shut off the engine, disconnect the spark plug wire,

and allow all moving parts to come to a complete stop and cool. Inspect for clogging or damage. Clean and repair and/or replace damaged parts.

 See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by DR

Power Equipment.

 Always keep the equipment in a good safe operating condition. Always make certain nuts and bolts are tight and always use

the supplied self-locking hardware; do not substitute.

Make sure you do not shorten the Hose too much while following these procedures. Follow the steps closely to ensure the machine is not damaged.

NOTE: The Tractor must be turned fully to the left (Figure 21).

a. Loosen the Hose Clamp that secures the inlet Hose to the Inlet Elbow

with a 5/16" Wrench and pull the Hose from the Elbow (Figure 22).

b. Position the Hose beyond the Elbow to where the slack is taken up but

still has a small amount of sag (Figure 23).

c. Cut the Hose to the length required using Wire Cutters to cut the black

plastic spiral and then cut the clear Hose with the razor knife.

NOTE: Make sure you trace the area to cut around the Hose first to ensure you will

cut in the proper direction to end up on either side of the cut spiral.

d. Reinstall the Hose as far as you can

onto the Elbow with the cut end of the

Inlet Hose

spiral on the bottom and tighten the Hose Clamp. If the Tractor can be turned fully to the left, without the Hose becoming too tight (with a slight amount of sag), the Hose is the shortest length possible for your Tractor.

NOTE: DR Power offers a Hose Support

Operating Safety

 Never put your hands inside the vacuum hose or the chipper hopper to clear debris while the engine is running. Always stop

the engine and disconnect the spark plug wire before clearing the vacuum hose or chipper hopper.

 For best results, use a small stick to clear a clogged chipper hopper.  The maximum size material that you can feed into the chipper hopper is 2 inches in diameter.  Always keep your face and body back from the chipper hopper opening to prevent any material that may bounce back from

striking you.

 Do not refuel the engine while it is hot or running.

Use common sense when using the machine. Learn to recognize the change in sounds when overloaded. Stop the engine immediately if the machine becomes jammed to prevent damage to the machine.

The DR LEAF and LAWN VACUUM has an Impeller that spins at 3400 rpm and a chipper feature that will chip wood up to 2 inches in diameter.

Towing the DR LEAF and LAWN VACUUM

1. Make sure you firmly attach the DR LEAF and LAWN VACUUM Hitch to your

Lawn Tractor using the Clevis Pin and Hitch Clip (Figure 27).

2. Remove the Jack Hitch Pin, fully raise the Jack Caster Wheel and re-install

the Jack Hitch Pin.

3. Make sure the Collector Base is secured onto the Frame with the Dump

Lever locked to the Latch on the Collector (Figure 28), the Outlet Hose Cuff is clamped tightly (Figure 29), and the Inlet Hose Cuff is securely attached to the Hose Adapter on your Tractor (Figure 30).

 Raise the Jack caster wheel as far as it will go prior to towing this

equipment. An extended Jack caster wheel can be damaged or deformed if it hits the ground or an object.

 The DR Leaf and Lawn Vacuum is not equipped for highway use.

Towing Safety



 Watch out for low branches, overhangs, and guy wires that may catch on top of the collector box.  Never allow anyone to ride in or on the DR Leaf and Lawn Vacuum.  Obey local, state, and federal regulations when you tow the DR leaf and lawn vacuum across public roads and highways.  Use caution when backing up your lawn tractor or trying to make tight turns going forward with the DR Leaf and Lawn

Vacuum attached. Trying to turn too sharply can cause damage to the hitch and/or the lawn tractor if you hit an obstacle. Go slowly in areas where tight turns are necessary. Straighten out the system before attempting to back up.

Slopes and Uneven Terrain

Never operate your machine on slopes greater than 15 degrees (Figure

31). When operating the DR Leaf and Lawn Vacuum over uneven terrain

and slopes, use extreme caution to not tip over the machine. Move slowly, especially with a full load, if the ground has ruts, bumps, and other

15º Max.

Figure 31

depressions.

 Do not use the DR Leaf and Lawn Vacuum on slopes greater than 15

degrees. Doing so could result in serious injury or damage to your machine.

 On a slope, a heavy load will tend to shift. When using your DR Leaf and

Lawn Vacuum, keep in mind that loads tend to shift to the downhill side of the collector box. The higher and heavier the load, the greater the chance you may tip over the machine.

 Travel up and down slopes and avoid going across slopes. This is the

same recommendation for mowing with your lawn tractor alone.

Figure 32

20 DR

Chipper Hopper

LEAF and LAWN VACUUM

Operating the Chipper (not available on Premier Machines)

In addition to towing the DR LEAF and LAWN VACUUM with your Lawn Tractor, and using it as a vacuum, the system also allows you to chip sticks and limbs up to 2" in diameter.

To prevent damage to your chipper, feed only wood up to 2" in diameter

into the chipper hopper.

 Never use your hand to push the remaining wood stub down into the

chipper hopper or try to remove a lodged piece of wood with the engine running.

1. Start the Engine in accordance with “Starting and Stopping” on page 18.

2. To process branches; feed them into the Chipper Hopper opening (Figure

32).

3. As the chipped branch shortens, finish chipping it by pushing the stub down

the Hopper with the next branch to be chipped.

Tips:

 It is best to trim off any side twigs from the main branch being

chipped (Figure 33).

 Green branches process quicker and easier than dry branches and

soft wood is easier than hardwood.

 Use caution with small diameter green saplings and branches. Chip

these grouped or bundled together to provide support for each other.

 Make sure the Chipper finishes chipping material in the Hopper

before shutting the engine off.

Dumping

Figure 33

 Always shut off the tractor engine and the vacuum engine and use caution

when dumping the collector box load.

 The load may have shifted against the rear panel. Push down on the

dump handle when releasing the dump lever to prevent the Collector Base from suddenly tipping.

 Never back up with the trailer in the dump position.

1. Move the Lanyard off the Outlet Hose Cuff and down onto the Outlet Duct

(Figure 34).

2. Disconnect the Outlet Hose from the Outlet Duct by loosening the

Thumbscrew Clamp and pulling the Hose away.

3. Remove the Back Panel of the Collector by unscrewing the two Knobs until

loose (the Knobs remain attached to the Back Panel)(Figure 35). Pull back on the two Back Panel Handles to separate the bottom of the Back Panel and pull down to remove the Back Panel from the Collector.

1. While holding down on the Dump Handle, pull the Dump Lever (Figure 36)

to unlock the Collector Base and then raise the Collector Base using the Dump Handle to dump the Collector.

2. After dumping the load, lower the Collector until the Dump Lever locks into

place onto the Latch (Figure 36), and replace the Back Panel (Figure 35).

3. Re-connect the Collector Hose to the Outlet Duct (Figure 34). Tighten the

Thumbscrew Clamp and slide the Lanyard back into position onto the Cuff of the Outlet Hose.

LEAF and LAWN VACUUM Tips

Pick up stones, metal objects, glass, and sticks before vacuuming.

1. Gather and pile sticks for chipping.

2. Chip the sticks and branches.

3. Dump the load at the desired location.

4. Mow and vacuum leaves.

Tips:

 Be careful in corners. Practice in first gear to understand the effects of the machine on your ability to turn sharply.

Drive your DR LEAF and LAWN VACUUM into the corner of your property and back out straight to mow as close to the corner as possible. Do not go through ditches.

 The Lawn Deck of your mower may tend to scatter some leaves in front and to the right of the Lawn Deck. Keeping the

discharge side toward the remaining leaves will simplify cleanup by avoiding blowing leaves back onto the areas that you already finished. When you need to vacuum with the discharge side toward the completed area of the lawn, overlap the discharge side of the Lawn Deck at least a foot over the already completed section of the lawn.

 To prevent clogging the Lawn Deck Adapter, mow grass that is dry and not more 2" at a time. To keep your grass

healthy, we recommend cutting less than 1/3 the grass height.

 Run your Lawn Deck with your Tractor at full throttle all the time to maximize the lift from your Lawn Deck and assist

your DR LEAF and LAWN VACUUM system.

 Avoid dragging the Hose over curbs, stonewalls, or piles of cut branches. The Hose is tough, but can puncture on

sharp objects. This could also crack the Mower Deck Adapter.

Battery Care (For Electric-Starting Models Only)

Proper care can extend the life of a Battery. Follow these recommendations to ensure your Battery’s best performance and long life:

 Do not allow the Battery charge to get too low. If the machine is not used, charge the Battery every 4 – 6 weeks. Operate the

engine for at least 45 minutes to maintain proper Battery charge.

 Store an unused Battery in a dry area that does not freeze.  Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle charger; however, when a

Battery is fully charged and the charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery will read 12V-13.2V with a voltmeter.

 Do not continue to crank your Engine when the Battery charge is low.

Charging the Battery

When you are finished charging the battery, disconnect the charger from the outlet first, then disconnect the battery charger wires from the battery. If you leave the battery charger wires connected to the battery, the battery will discharge itself back into the charger.

Operate the vacuum Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you will need to use a trickle charger (like the DR Battery Charger) to recharge it. The Charger should have an output of 12 volts at no more than 2 amps.

 At 1 amp the Battery may need to be charged for as long as 48 hours.  At 2 amps, the Battery may need to be charged for as long as 24 hours.

NOTE: Using the Recoil Starter and then running the Engine will not recharge a dead or significantly discharged Battery.

To connect a Battery Charger to your DR LEAF and LAWN VACUUM, follow the steps listed below.

1. Attach the Black (-) alligator clipped wire from the Charger Adapter to the Negative (-) terminal of the Battery, then attach the

Red (+) alligator clipped wire to the Positive (+) Battery terminal.

2. Plug the Charger into a standard wall outlet.

 Typically, the Battery takes between 6 and 8 hours to fully charge. The Battery does not have a “memory”; so don’t

worry about overcharging the Battery or charging it too often.

 You can charge the Battery many times. The Battery lasts longer if you charge it before it is fully drained. Keep it fully

charged and at room temperature when not using your DR LEAF and LAWN VACUUM.

 If the Battery does not hold its charge for very long under normal conditions or it simply won’t hold a charge, then

replace it. You can purchase replacement Batteries directly from us. To install your new Battery, follow the directions below.

Tools Needed:

 Two 7/16" Wrenches

Battery Clamp

Figure 54

Battery Terminals

Bolt and Locknut

1. Disconnect the Battery Terminals (Figure 54).

2. Remove the Bolts and Locknuts that secure the Battery Clamp using two

7/16" Wrenches.

3. Remove the Clamp and the dead Battery.

Tip: Rotating the Battery will aid in removal.

4. Install the new Battery.

5. Install the Battery Clamp and secure with the Bolts and Locknuts using two

7/16" Wrenches.

6. Attach the Battery Terminals. Green Wire to negative black Terminal and

Red Wire to positive red Terminal.

Disposing of the Battery Responsibly (Electric-Start Models)

The Battery is a sealed lead-acid Battery. Recycle or dispose of it in an environmentally sound way.

 Do not dispose of a lead-acid Battery in a fire; the Battery may explode or

leak.

 Do not dispose of a lead-acid Battery in your regular, household trash. Law in

most areas prohibits incinerating, disposing in a landfill, or mixing a sealed lead-acid Battery with household trash.

Recycling a Used Battery

Please dispose of your used Batteries responsibly by recycling them. Call your local Solid Waste Management District or your local waste handler to locate the collection site nearest you. Some collection sites recycle Batteries year-round; others collect them periodically.

You can also visit the Web site of Earth 911 for more information [www.earth911.org]. Once there, click the Municipal HHW link under Hazardous Household Waste, and enter your zip code. The site lists recycling centers located near you.

For a fee, you can recycle your Batteries with the International Metals Reclamation Company. Visit them at www.inmetco.com and click Services; or contact them at:

INMETCO PO Box 720 245 Portersville Road Ellwood City, PA 16117 (724) 758-2825; fax (724) 758-2845

Daily Checklist for the DR LEAF and LAWN VACUUM

To help maintain your DR LEAF and LAWN VACUUM for optimum performance, we recommend you follow this checklist each time you use your Vacuum.

[ ] OIL: With the machine on a level surface, remove the Oil Fill Cap and check the oil level. Fill the reservoir according to

the Dipstick with the recommended motor oil.

[ ] GAS: Fill the gas tank with fresh, unleaded gasoline.

[ ] ENGINE: It is very important to keep the Engine clean. Remove dirt and other debris from the Engine cooling fins and

debris guard. A dirty Engine retains heat and can cause damage to internal Engine components.

[ ] HARDWARE: Check all nuts and bolts to be sure that the components are secure.

[ ] FRAME: Check all welds to be sure that the frame is in tact and secure.

[ ] HOSES: Inspect the Hoses for holes, frayed, worn, kinked, or abraded areas. Replace any damaged or worn Hoses.

End of Season and Storage

NOTE: Please refer to the Engine Owner’s Manual for engine-specific procedures.

 Change the oil. Refer to your Engine Owner’s Manual for detailed information.  If your DR LEAF and LAWN VACUUM 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.

 Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the plug and pull the recoil

starter rope until you feel strong resistance. This will coat the piston and seat the valves to prevent moisture buildup.

 Clean or replace the air filter. Refer to your Engine Owner’s Manual for detailed information.  Clean dirt and debris from the cylinder head cooling fins, Impeller housing, debris screen, and muffler area of the engine.  Clean out residual debris from the Hoses and Collector.  Store the Battery in a dry area that will not freeze. If you will not use the machine over a long period, charge the Battery

every four to six weeks. See page 28.

 If possible, store the DR Leaf and Lawn Vacuum in a dry, protected area. If it is necessary to store the machine outside,

cover it with a protective material (especially the Engine). Contact us at www.DRpower.com or call 1-800-DR-OWNER (376-

9637) to purchase a cover for your DR LEAF and LAWN VACUUM.
