Protecting Yourself and Those around You
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 activity. Never assume that children or pets will remain where you last saw them. Always follow
these precautions:
•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 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 down for small children and pets. You cannot see directly behind the
collector box.
•Never allow children to operate the Lawn Tractor or Vacuum.
•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.
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 impeller 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, the vacuum
system, or when 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 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 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
General Safety
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.
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.
•Never run the engine unless the chute, fabric collector sleeve, and hose are all securely in place and the engine frame is
securely connected to the cart frame.
•Check behind your DR Leaf and Lawn Vacuum before backing up. You cannot see directly behind the collector box.
•Never attempt to open or empty the collector while the lawn tractor deck is engaged or the DR Leaf and Lawn Vacuum engine
is running. Debris may exit at high velocity as you begin to open the collector.
•Do not operate in sandy areas where you will vacuum large quantities of sand. Sand will erode the vacuum housing. Check
for holes after each use and replace the housing and liner when holes develop.
•Never operate the machine on slopes greater than 15 degrees.
•Never tow the DR Leaf and Lawn Vacuum faster than 8 mph.
•Always shut off the lawn tractor engine and the DR Leaf and Lawn Vacuum engine and disconnect the spark plug wire before
attempting to clear any obstructions from the hose.
•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.

4. For Machines with Dual Wheels only: Slide a Wheel onto the Axle with the
Valve Stem facing in and install a Washer against the Wheel (Figure 10).
Note: No Washers are needed against the Axle Brackets. Dual Wheel machines use
one washer between the Dual Wheels and one on the outside. Single Wheel
machines only use one Washer on the outside.
5. For all Machines: Install a Wheel (second wheel for Dual Wheel models)
with the Valve Stem facing out and place a Washer against the Wheel
(Figure 11).
6. Secure the Wheel/s onto the Axle with a Cotter Pin. Use Pliers to bend the
ends of the Cotter Pin to secure the Wheels.
7. Repeat for the Wheel/s on the opposite side.
8. Tighten axle bracket hardware.
9. Tip the Cart over onto the Wheels.
Installing the First Gas Spring
1. Tilt the Cart Bed up by pulling the Lift Handle out and lifting up on the
front of the Cart (Figure 12).

orient as shown) and secure with four Bolts, Lock Washers, and Flat
Washers using a 1/2" Wrench or socket (Figure 16) .
Installing the Power Unit
(Use Power Unit Hardware Package, see Figure 6)
1. Position the Power Unit at the front of the Cart with the Tow Hitch
facing forward and the rear holes aligned.
2. Lift the Cart Frame to align the rear hole in the Engine Unit with the hole
in the Frame and insert a 1/2" X 3.5" Clevis Pin and Hitch Clip (Clevis
Pins and Hitch Clips are provided in the Product Package (Figure 18).
3. Chock the Wheels of the Cart to keep it from moving and have a helper
pull forward on the Outlet Chute so the Power Unit and Cart Frame front
holes are aligned (Figure 19).
Note: If you have a Floor Jack or similar you could jack under the Dump Lever to
align the Frames without a helper.
4. Insert the 2nd 1/2" X 3.5" Clevis Pin and Hitch Clip into the front holes of
the Engine Unit and Cart Frame (Figure 20).
5. Place the two 1/2-13 X 2.75" Bolts from underneath up through the two
vertical Holes and secure with 1/2-13 Locknuts using a 3/4" Wrench and
3/4”Ratcheting Socket. Remove the Floor Jack if one was used.

Assembling the Collector
(Use Enclosure Hardware Set, see Figure 7 and Product Package
Hardware, see Figure 3)
Note: The Enclosure Fabric is intentionally a tight fit. Assembly is
much easier when you perform the following procedures in order.
Tools Needed:
•7/16" Deep Socket with Ratchet
•7/16" Wrench
•1/2”Deep Socket with Ratchet
•1/2" Wrenches
•9/16”Deep Socket with Ratchet
•9/16”Wrench
•Hammer
Installing the Inner Link Assembly
1. Remove any bubble wrap packaging from each Tube Frame and stand up both the LH and RH Tube Frames against a wall,
making note of the Pin Orientation shown (Figure 21).
2. Orient the Inner Link Assembly onto the Tube Frames with the jogged bent link as shown (Figure 22).
3. Secure the links with hardware found in the Product Package (Figure 3) by inserting two carriage bolts (Bolt, C-Head, 5/16-
18 X 1.75) through the tube, followed by two washers (Washer-Flat 5/16 USS), the scissor links and then two lock nuts (Nut-
Lock Nylon 5/16-18) as shown in (Figure 23).
4. Tighten the lock nuts using a 1/2" Wrench just enough to engage the nylon end on the nuts. Making sure the carriage bolt is
seating correctly in the square tube hole. Do not over tighten, as the scissor links need to be able to rotate freely once
secured.

Installing the Side Retainers
1. Lay out the Enclosure onto a clean flat surface so the inside (black) is
facing up (Figure 27). Take note of the Sleeve location at the front of
the Enclosure.
2. Fold the side flaps so you can see the 5 holes in each of the side
pockets. Take note of the front pocket. It also has holes, but they are
facing down and are not visible (Figure 27).
3. Set the Tube Frame Assembly into the Enclosure with the Inner Link
positioned toward the Rear Flap (opposite the Front Sleeve) (Figure
28).
Note: The Left Hand and Right Hand Side Retainers are very similar and their
orientation needs to be checked prior to inserting into the canvas
enclosure.
4. Check that the left hand and right hand side retainers are oriented correctly by holding up one retainer at a time. With the
retainer on the outside, feed the studs through the Tube Frame Slots. The parts will be oriented correctly if all 5 studs feed
through the Slots without issue. Once you have confirmed both retainers are in the correct orientation, lay them down
(keeping its same orientation) next to the Enclosure Pocket with the studs pointing up (Figure 28).
5. Insert the front end of the Side Retainer into the rear end of the pocket so when installed the Side Retainer will be in the
same orientation shown in the photo. It works best to keep the studs tilted sideways until they all align with the Enclosure
holes, then twist the Retainer so the studs go into the holes (Figure 29).
6. Repeat steps 4 and 5 for the other Side Retainer.

Attaching the Enclosure,
(Use Hardware Enclosure set, see Figure 7)
It is best to do this install up against a wall, to keep the enclosure upright while
working.
1. Lift one side of the Enclosure so the studs on the Side Retainer go into the Tube
Frame Assembly slots (Figure 30). Secure with five 1/4-20 Lock Nuts. Screw the
nuts onto studs finger tight.
Note: It is important that the nuts are only finger tight as it will allow the canvas to be
pulled around much easier to align other areas of the frame and canvas.
2. Repeat step 1, lifting up the other side.
3. At the Rear Flap corner, align the two holes of the Enclosure and Tube Frame
Assembly. Insert two 5/16-18 x 2-1/4”bolts into each hole and through to the
outside of the canvas (Figure 31).
4. Repeat step 3 for the other back corner.
5. Put one 5/16 Flat Washer on each of the 4 exposed bolts.
6. Align the Outer Link Assembly “L”bracket onto the two rear
corner bolts and washers, screw on 5/16-18 nuts finger tight. Be
sure to orient the Outer Link Assembly with the Link Bend where
shown (Figure 32).
7. Repeat step 5 for the other corner.
8. Next, we need to align the front corner. Pull the canvas to align
the front corner holes with the Tube Frame. Insert two 5/16-18 x
1-3/4”bolts through the Tub Frame and canvas. Leaving the
exposed thread outside the canvas (Figure 33).
9. Repeat step 8 for the other corner.
10. Tighten four Thumb Screw Knobs onto the ends of the four
exposed bolts to keep them in place while we install the
remaining components.

Installing the Front Retainers
1. Insert one of the Front Retainers into the Front Corner canvas pocket. Slide the Front Retainers in at an angle to avoid the
studs catching on the canvas as they are inserted (Figure 34).
2. Align the studs through the holes in the canvas (Figure 35).
3. Repeat steps 1 and 2, inserting the remaining Front Retainer into the canvas from the other front corner.
4. Screw on four Thumb Screw Knobs finger tight onto each of the four exposed studs to keep the retainers from moving while
we install the other components.
Installing the Hinge Tube Assembly (Figure 36)
1. Lay the Hinge Tube Assembly into the canvas with
the eyebolt laying flat on the canvas floor as shown
in Figure 37.
2. Align one end of the assembly underneath the
Tube Frame Pin. Insert the pin through the inner
hole on the Hinge Tube ends.
Note: The outer holes on the Hinge Tube Assembly
should only be used if the canvas needs to be adjusted
tighter, once fully assembled.
3. Secure the Hinge Tube Assembly onto the pin with
a hair pin (Pin, Cotter, Hair, 1/4-3/8) that can be
found in the Product Pack (Figure 38).
4. Repeat steps 2 and 3 to secure the other end of the
Hinge Tube Assembly to the frame.

Setting the Initial Canvas Width
1. Step into the open canvas and push the sides out with both feet to
aid in setting the canvas width.
2. Set the Inner Scissor Link assembly width by pushing down on the
flat link until both parts come to parallel. When parallel, slide the
ring link across to prevent the scissors from coming apart (Figure
39).
Note: The canvas is intended to be tight but if the scissor links start to
bow out, an adjustment can be made. You can adjust the center bolt
and nut to another hole location to reduce the difficulty of this action
(Figure 40).
3. Next set the width of the front of the canvas by pushing in the Tube
Hinge Assembly until both tube parts come together and the
threaded stud feeds through the open slot. Make sure the Eyebolt is
able to feed through the Canvas Hole during the process (Figure 41).
4. With both Tube Hinge parts coming together, secure them with a
Thumb Screw Knob onto the threaded stud. Screw until tight (Figure
42).

Installing the Front Split Hinge
(Use Hardware Enclosure set, see Figure 7)
1. First assemble the Front Split Hinge by joining the RH and LH
Split Hinge parts, oriented as shown in Figure 43. Fasten them
together with one 3/8-16 X 2 3/4 Bolt and one 3/8-16 Low profile
Nut using two 9/16”Wrenches. Do not overtighten, as these
two components will need to rotate about one another.
2. Next, slip the Split Hinge Assembly through the canvas opening
in the front corner, making sure the rolled hinges are oriented
up and the Retainer Studs pass through the holes in the hinge
(Figure 44).
3. Secure the hinge onto the Retainer Studs with Thumb Screw
Knobs loosely fastened.
4. Inside the canvas, position the Split Hinge to the Tube Frame by aligning the hinge to the outer most hole on the frame
(Figure 45).
Note: The inner hole on the tube frame is to allow for adjustability if the canvas loosens over time and needs to be tightened.
5. Secure the Split Hinge to the Tube Frame by dropping in one 3/8-16 X 2 3/4 Bolt and finger tightening one 3/8-16 Low
profile Nut.
6. Repeat steps 2 through 5 in the other corner to fully secure the hinge to the canvas and the frame.
7. With the Split Hinge now positioned correctly, fully tighten down all four Thumb Screw Knobs.
8. Tighten down the 3/8-16 Bolts and Nuts to engage the nylon lock using a 9/16”wrench and 9/16”ratcheting socket. Ensure
the Split Hinge can still rotate about the Tube Frame after tightening.
