Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and
the vacuuming activity. Never assume that children will remain where you last saw them.
•Keep children out of the work area and under the watchful care of a responsible adult.
•Be alert and always turn off the DR Walk-Behind Leaf and Lawn Vacuum engine if children or pets enter the work area.
•Before, and while moving backwards, look behind, and down for small children and pets.
•Never allow children to operate the vacuum.
•Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.
This is a high-powered machine, with moving parts operating with high energy at high speeds. Use proper clothing and safety
gear when operating this machine to prevent or minimize the risk of severe injury. 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 operating this machine:
•Always wear protective goggles or safety glasses with side shields while operating this vacuum system to protect your eyes
from possible foreign objects thrown from the machine.
•Wear shoes with non-slip treads when using your DR Walk-Behind Leaf and Lawn Vacuum. If you have safety shoes, we
recommend wearing them. Do not use the machine while barefoot or wearing open sandals.
•Avoid wearing loose clothing or jewelry, which can catch on the machine’s moving parts.
•We recommend wearing gloves while using your DR Walk-Behind Leaf and Lawn Vacuum. Be sure your gloves fit properly
and do not have loose cuffs or drawstrings.
•We recommend changing the debris bag after vacuuming glass and other debris and before using the system to vacuum
material that may be used for compost or mulch.

Slopes are a major factor related to slip and fall 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 across the face of slopes; never up and down. Exercise extreme caution when changing direction on slopes.
•Remove objects such as stones, wire, rope, or rags.
•Watch for holes, ruts, or bumps in the landscape.
Never:
•Never vacuum near drop-offs, ditches, or embankments; you could lose your footing or balance.
•Never vacuum on slopes greater than 20 degrees, or any excessively steep slopes.
•Never vacuum on wet, or slippery slopes; reduced traction could result in slipping.
•Never park the vacuum on a steep grade or slope.
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 operate the engine with the air cleaner or cover over the carburetor air-intake removed, except for adjustment. Removal
of such parts could create a fire hazard. Do not use flammable solutions to clean air filter.
•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.
•Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Do not handle gasoline if you or
anyone nearby is smoking, or if you are near anything that could cause it to ignite or explode. Replace the fuel tank and fuel
container caps 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 and empty the debris bag before storing the DR Walk-Behind Leaf and Lawn Vacuum in
any enclosure. Remember, decomposing material generates heat and could 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.
•Never make adjustments or repairs with the engine running. Disconnect the spark plug wire and keep the wire away from the
spark plug to prevent accidental starting.
•Never check for an ignition spark with the spark plug or spark plug wire removed. Use an approved spark tester.
•Never tamper with safety devices. Check their proper operation regularly.
•Never change the engine governor settings or modify the engine speed. Modifications will void your warranty.
•To reduce fire hazard, keep the engine and muffler area free of debris build-up such as leaves, grass, Oil, grease, or any other
combustible material. Clean the engine area after each use.
•Never operate the engine without the muffler. Inspect the muffler periodically and replace if necessary. If equipped with a
muffler deflector, inspect the deflector periodically and replace if necessary.
•The muffler and engine become very hot and can cause a severe burn; do not touch.
•Always check fuel lines and fittings frequently for cracks or leaks, replace if necessary.
•Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.

Using the Chipper Chute
The Chipper can chip twigs and branches ranging in size up to 1.5" in
diameter. Cut your materials into manageable lengths before feeding them
into the Chipper Hopper. The revolving Chipper Knife mounted on a Rotor,
turns branches fed into the Hopper into “chips”.
•Be sure that the collection bag is in place and has enough room for the
new debris before chipping.
•Always wear safety goggles, gloves, and hearing protection when
chipping.
•Start the Engine on level ground.
•Keep a moderate feed rate to prevent overloading the machine.
•Use common sense when using the chipper. Learn to recognize the
change in sound when the Engine is overloading. Pull back on the material you are chipping if overloading should occur.
•Green or dry branches chip easily and soft wood will chip easier than hard wood.
•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.
•Some side shoots or side branches may have to be trimmed from the main stalk before chipping.
•Short stubs of branches may be pushed through the Chipper section with the next branch. NEVER ALLOW YOUR HANDS
TO ENTER THE CHIPPER CHUTE. If necessary, push the material further down with a long stick or branch.
•When chipping branches occasionally a “tail” will be left at the end of the branch (usually green wood), which increases in
length as you chip and eventually wraps around the shaft. To avoid this, slowly turn the branch as you feed it into the
Chipper tube. This will also improve the chipping performance.
•When chipping, frequently empty the Collection Bag to make it easier because of the weight of the accumulative chips.
•If the machine does not chip well, the Chipper Knife may need to be replaced.
Using the Vacuum
•Before leaves drop, mow your lawn to the shortest recommended height. Your DR WALK-BEHIND LEAF AND LAWN
VACUUM will perform better on short grass.
•The DR WALK-BEHIND LEAF AND LAWN VACUUM is designed to be used frequently during periods when leaves are
dropping. It is not recommended to let leaves get 4″, or deeper.
•The drier the leaves the better.
•The thicker the leaf layer the slower you should proceed. If leaves are wet or matted down use light pressure on the Drive
Lever and it may be necessary to fluff up leaves before using the vac. If the snout clogs, try going at a slower speed.
•Snout height is critical. The snout should be positioned just above the leaf layer to allow proper vacuuming. As a general
reference, the front of the snout should scrape the top of the grass.
•You should avoid vacuuming twigs and branches into the snout. This will cause clogging. Twigs and branches should be
processed through the Chipper Chute.
•Avoid overfilling the Vacuum Snout, this will cause clogging.
•Vacuuming wet and soggy material will also cause clogging. A steady pace with a smaller flow of materials provides the
most effective results.
•Avoid clogging when vacuuming loose, stringy material such as hay or pine straw, by picking up a small amount at a time.
Check and empty the Collection Bag frequently.
•Avoid vacuuming in sandy areas, as this will cause excessive wear.
•Use care when vacuuming near plantings, ornamentals, mulches.
•Use extra caution when vacuuming around stone and gravel.

16 DR® LEAF and LAWN VACUUM
Adjusting the Vacuum Snout Height
The height of the Vacuum Snout can be adjusted to allow you to vary the
suction to meet the surface conditions.
•For short turf with light leaf fall, the Snout should be lowered closer to
the surface.
•For long turf and heavy leaf fall, the Snout should be raised above the
debris.
•For moving the machine long distances, you will avoid damage to the
snout by raising the Snout to the highest setting.
1. To raise the Snout: Pull the Height Adjust Handle out of the slot and move it forward to the next desired slot (Figure 26).
2. To lower the Snout: Pull the Height Adjust Handle out of the slot and move it rearward to the next desired slot.
Clearing the Machine of Debris Clogs
A clog in the machine can cause the vacuuming , shredding, and chipping
operations to decrease or even stop completely. If clogging occurs, check
(and clean if necessary) the following areas.Tools needed:
•1/2" Wrench
•Stick
1. Make sure the machine is off and the Impeller has stopped spinning.
2. Remove any material left in the Chipper Hopper with a stick (XTSP
Models).
3. Lift the Bag Cover Latch to open the Cover fully.
4. Check that the Collection Bag is not overfilled. Empty the Bag if Full.
5. Check the end of the Hose for debris buildup inside the Bag Top Cover. Remove any buildup and close the Cover. If you
found and removed debris from the Bag Top Cover, you can try turning the machine on to see if the clog is cleared, or if
the machine will be able to clear the remaining clog itself. If you find the machine is still clogged, turn the machine off and
make sure the Impeller has stopped spinning before continuing on to step 6.
6. Remove the four Bolts that secure the Outlet Tube to the Impeller using a 1/2" Wrench (Figure 27). Remove the Outlet
Tube from the Impeller Housing.
7. Remove any clogged debris from the Hose and Impeller Housing.
8. Reinstall the Outlet Tube and fasten it to the Impeller housing with the four bolts.

Changing The Engine Oil
Tools and Supplies Needed:
•Engine Oil (see your Engine Manual for Oil specifications)
•Oil Extractor*
•Small Funnel
•Rags
*The Engine does not have a Drain Plug. An Oil Extractor can be used to
remove Oil. Visit our website to purchase an Oil Extractor.
Note: Remove the Oil when the Engine is warm. Warm Oil siphons quicker
and more completely.
1. Remove the Engine Oil Fill/Dipstick. (Figure 36).
2. Use an Oil Extractor to remove the Oil from the Engine.
3. Initially add 14 oz. of Oil (type recommended by the Engine
Manufacturer) into the Oil Fill and wait one minute for the Oil to settle.
4. Check the Dipstick and continue adding a few ounces of Oil at a time, rechecking the Dipstick until the Oil reaches the fill
mark. Be careful not to overfill.
Bag Maintenance
•Store bags in a dry area.
Adjusting the Traction Drive Cable (Model XTSP)
Note: When properly adjusted, tension on the Traction Drive Lever should increase when the Lever is about parallel to (almost
touching) the Handlebar Grip.
1. Locate the Traction Drive Cable along the Right Side of the Handlebar
(Figure 37). There is an In-Line Adjuster to change the length of the
Cable.
2. Rotate the center portion of the In-Line Adjuster clockwise while holding
the ends stationary to expand the In-Line Adjuster and remove slack
from the Cable.

Removing/Replacing the Chipper Knife (PILOT XTSP)
The PILOT XTSP model is shipped with a sharp Chipper Knife and, depending
upon material being chipped, will remain acceptably sharp for 40 plus hours.
When you notice diminished feeding, it is time to replace the knife. You may
also choose to have the knife sharpened instead as described on the next page.
Tools and Supplies Needed:
•1/2" Wrench
•7/16" Wrench
•Awl
•4mm Allen Wrench
1. Remove the three Bolts that secure the Chipper Chute to the Housing using
a 1/2" Wrench (Figure 38). Remove the Discharge Chute from the Frame
and set it aside to gain access inside the Impeller Housing.
2. Remove the four Bolts securing the Discharge Chute to the Frame using a
1/2″Wrench.
3. Clean out the Allen Screws using an Awl.
4. Hold the Allen Screw from turning using a 4mm Allen Wrench as you remove the Locknut from the underside of the
Impeller using a 7/16″Wrench. Remove the second Bolt and Lock Nut to remove the Knife.
5. Visually inspect the Knife mounting surface and be sure it is clean. Metal burrs may need filing so the Knife mounts flush
against the Flywheel.
6. Install a new or sharpened Knife with the sharp edge toward the Slotted Opening (Figure 39). Install In reverse order of
removal, inserting the Screws first.
Note: It is important that you use the new Allen Screws and Lock Nuts provided with each new Chipper Knife.
7. Reinstall the Outlet Tube and Chipper Chute.
Replacing the Drive Belt (PILOT XTSP)
Tools and Supplies needed:
•1/2" Wrench
•Pliers
•Diagonal Cutting Pliers
1. Locate a clean flat surface to work on.
2. Remove the two Bolts that Secure the Belt Cover to the Frame using a
1/2" wrench (Figure 40). Remove the Belt Cover.
3. Look closely at the Belt to find a small black arrow (Figure 41). The black
arrow shows the direction of rotation. The arrow would be pointing left
when viewed from the left side of the machine. The new Belt will need to
be installed in the same direction for the Belt to work properly.

Note: Another way to quickly tell what direction the Belt should be assembled
is to see what direction the “V” shaped opening is pointing. The “V”
is pointing right when viewed from the left side of the machine.
4. Cut the old Belt to be replaced using Diagonal Cutters or equivalent
and remove Belt from the Pulleys.
Note: You may want to practice assembling the Linked Belt out of the
machine before it is in placed inside where there is limited access. See
the following section “Assembling the Belt Links”.
5. Before connecting the belt into a loop, route the belt around the pulley
under the engine. Make sure the black arrow marked on the belt is
pointing left when viewed from the left side of the machine.
6. Assemble the belt links together to form a continuous belt.
7. Roll the belt over the Pulley as you turn the Pulley until the Belt falls fully into the groove of the Pulley. Check that the Belt
is seated in the groves of the Drive and Impeller Pulley’s
8. Replace the Belt Cover and the two Bolts using a 1/2”wrench.
