General Safety Information
1. GENERAL SAFETY INFORMATION
1.1. SAFETY ALERT SYMBOLS AND SIGNAL WORDS
SPECIAL NOTE: This manual contains information pertaining to both the chassis (trailer portion)
of the leaf vacuum, as well as the equipment mounted on the chassis. Throughout this manual,
the complete pull behind leaf vacuum will be referred to as a trailer, as this is how it is classified
by federal law. All rules and regulations pertaining to the operation of “regular trailers” also apply
to this ”leaf vacuum trailer”.
ANOTHER SPECIAL NOTE:An Owner’s Manual that provides general trailer information cannot
cover all of the specific details necessary for the proper combination of every trailer, tow vehicle
and hitch. Therefore, you must read, understand and follow the instructions given by the tow
vehicle and trailer hitch manufacturers, as well as the instructions in this manual.
AND ONE MORE: This trailer is 102” wide, which is within legal towing width for all US interstates
and federally designated state highways. When operating on other roadways, consult local and
state laws regarding legal towing width.
Our trailers are built with components produced by various manufacturers. Some of these items have
separate instruction manuals, and many are included in the supplemental manuals section. Where this
manual indicates that you should read another manual, but you do not have that manual, call Bonnell
Industries, Inc at 800-851-9664 for a free copy. See page 44 for a list of supplemental manuals that may
apply to this piece of equipment.
The safety information in this manual is denoted by the safety alert symbol: ^
The level of risk is indicated by the following signal words.
^ Danger
DANGER – Immediate hazards which WILL result in severe personal injury or
death if the warning is ignored.
^WARNING
WARNING – Hazards or unsafe practices which COULD result in severe
personal injury or death if the warning is ignored.
^ Caution
CAUTION – Hazards or unsafe practices which could result in minor or
moderate injury if the warning is ignored.
^ Notice
NOTICE – Practices that could result in damage to the trailer or other property.

General Safety Information
1.2. MAJOR HAZARDS
Loss of control of the trailer or trailer/tow vehicle combination can result in death or serious injury. The
most common causes for loss of control of the trailer are:
•Improper sizing the trailer for the tow vehicle, or vice versa.
•Excessive Speed: Driving too fast for the conditions.
•Failure to adjust driving behavior when towing a trailer.
•Improper or mis-coupling of the trailer to the hitch.
•Improper braking and steering under sway conditions.
•Not maintaining proper tire pressure.
•Not keeping lug nuts tight.
1.2.1. IMPROPER SIZING OF THE TRAILER TO THE TOW VEHICLE.
Trailers that weigh too much for the towing vehicle can cause stability problems, which can lead to death
or serious injury. Furthermore, the additional strain put on the engine and drive-train may lead to serious
tow vehicle maintenance problems. For these reasons the maximum towing capacity of your towing
vehicle should not be exceeded. The towing capacity of your tow vehicle, in terms of maximum Gross
Trailer Weight (GTW) and maximum Gross Combined Weight Rating (GCWR) can be found in the tow
vehicles Owner’s Manual.
^ Danger
Use of a hitch with a load rating less than the load rating of the trailer can
result in loss of control and may lead to death or serious injury.
Use of a tow vehicle with a towing capacity less than the load rating of the
trailer can result in loss of control, and may lead to death or serious injury.
Be sure your hitch and tow vehicle are rated for the Gross Vehicle Weight
Rating (GVWR) of your trailer.
1.2.2. DRIVING TOO FAST
With ideal road conditions, the maximum recommended speed for safely towing a trailer is 60 mph. If you
drive too fast, the trailer is more likely to sway, thus increasing the possibility for loss of control. Also your
tires may overheat, thus increasing the possibility of a blowout.
^WARNING
Driving too fast for conditions can result in loss of control and cause death or
serious injury.
1.2.3. ADJUSTING DRIVING BEHAVIOR TO MATCH CONDITIONS
When towing a trailer, you will have decreased acceleration, increased stopping distance, and increased
turning radius (which means you must make wider turns to keep from hitting curbs, vehicles, and anything
else that is on the inside corner). Furthermore the trailer will change the handling characteristics of your
towing vehicle, making it more sensitive to steering inputs and more likely to be pushed around in windy
conditions or when being passed by large vehicles. In addition, you will need a longer distance to pass,
due to slower acceleration and increased length. With these caveats in mind:

General Safety Information
Be alert for slippery conditions. You are more likely to be affected by slippery road surfaces when driving
a tow vehicle with a trailer, than driving a tow vehicle without a trailer.
Anticipate the trailer “swaying.” Swaying can be caused by excessive steering, wind gusts, roadway
edges, or by the trailer reaction to the pressure wave created by passing trucks and busses.
When encountering trailer sway take your foot off the gas, and steer as little as possible in order to stay
on the road. Use small “trim-like” steering adjustments. Do not attempt to steer out of the sway; you’ll only
make it worse. Also do not apply the tow vehicle brakes to correct trailer swaying. On the other hand,
application of the trailer brakes alone will tend to straighten out the combination, especially when going
downhill. Check rearview mirrors frequently to observe the trailer and traffic. Use lower gear when
driving down steep or long grades. Use the engine and transmission as a brake. Do not ride the brakes,
as they can overheat and become ineffective. Be aware of your trailer height, especially when
approaching bridges, roofed areas and around trees.
1.2.4. TRAILER NOT PROPERLY COUPLED TO THE HITCH
It is critical that the trailer be securely coupled to the hitch ball, and that the safety chains and emergency
break-away brake cable are correctly attached. Uncoupling may result in death or serious injury to you
and to others.
^WARNING
Proper selection and condition of the coupler and hitch are essential to safely
towing your trailer. A loss of coupling may result in death or serious injury.
Be sure the hitch load rating is equal to or greater than the load rating of the
coupler.
Be sure the hitch size matches the coupler size
Observe the hitch for wear, corrosion and cracks before coupling. Replace
worn, corroded or cracked hitch components before coupling the trailer to the
tow vehicle.
Be sure the hitch components are tight before coupling the trailer to the tow
vehicle.
^WARNING
An improperly coupled trailer can result in death or serious injury.
Do not move the trailer until:
The coupler is secured and locked to hitch;
The safety chains are secured to the tow vehicle; and
The trailer jack(s) are fully retracted.
Do not tow the trailer on the road until:
Tires and wheels are checked;
The trailer brakes are checked;
The breakaway switch is connected to the tow vehicle;
The load is secured to the trailer; and
The trailer lights are connected and checked.

General Safety Information
1.2.5. PROPER USE OF SAFETY CHAINS
If your trailer comes loose from the hitch for any reason, we have provided safety chains so that control of
the trailer can still be maintained.
1.2.6. PROPER CONNECTION OF BREAKAWAY BRAKE
Your trailer is equipped with a breakaway brake system that can apply the brakes on your trailer if your
trailer comes loose from the hitch ball for any reason. See page 99 for complete instructions regarding
the break-away system. The breakaway brake system, including battery, must be in good condition and
properly rigged to be effective.
^WARNING
An ineffective or inoperative breakaway brake system can result in a runaway trailer, leading
to death or serious injury if the coupler or hitch fails.
The breakaway cable must be connected to the tow vehicle, and NOT to any part of the hitch.
Before towing the trailer, test the function of the breakaway brake system. If the breakaway
brake system is not working, do not tow the trailer. Have it serviced or repaired.
1.2.7. MATCHING TRAILER AND HITCH
^ Danger
Use of a hitch with a load rating less than the load rating of the trailer can result in loss of
control and may lead to death or serious injury.
Use of a tow vehicle with a towing capacity less than the load rating of the trailer can result in
loss of control, and may lead to death or serious injury.
Be sure your hitch and tow vehicle are rated for the Gross Vehicle Weight Rating (GVWR) of
your trailer.
1.2.8. WORN TIRES,LOOSE WHEELS,AND LUG NUTS
As with any vehicle, the trailer tires and wheels are important safety items. Therefore, it is essential to
inspect the trailer tires before each tow.
If a tire has a bald spot, bulge, cut, cracks, or is showing any cords, replace the tire before towing. If a
tire has uneven tread wear, take the trailer to a dealer service center for diagnosis. Uneven tread wear
can be caused by tire imbalance, axle misalignment or incorrect inflation.
^WARNING
Improper rigging of the safety chains can result in loss of control of the trailer
and tow vehicle, leading to death or serious injury, if the trailer uncouples
from the tow vehicle.
Fasten chains to frame of tow vehicle. Do not fasten chains to any part of the
hitch unless the hitch has holes or loops specifically for that purpose.
Cross chains underneath hitch and coupler with enough slack to permit turning
and to hold tongue up, if the trailer comes loose.

General Safety Information
Tires with too little tread will not provide adequate frictional forces on wet roadways and can result in loss
of control, leading to death or serious injury.
Improper tire pressure causes increased tire wear and may reduce trailer stability, which can result in a
tire blowout or possible loss of control. Therefore, before each tow you must also check the tire pressure.
Remember, the proper tire pressure is listed on the Certification / VIN label, normally mounted on front
left side of the trailer, and should be checked when tires are cold. Allow 3 hours cool-down after driving
as much as 1 mile at 40 mph before checking tire pressure.
^WARNING
Improper tire pressure can result in a blowout and loss of control, which can lead to death or
serious injury.
Be sure tires are inflated to pressure indicated on sidewall before towing trailer.
The tightness of the lug nuts is very important in keeping the wheels properly seated to the hub.
Before each tow, check to make sure they are tight.
^WARNING
Metal creep between the wheel rim and lug nuts will cause rim to loosen and could result in a
wheel coming off, leading to death or serious injury.
Tighten lug nuts before each tow.
The proper tightness (torque) for lug nuts is listed in Section 6.2.9.2 in the “Error! Reference source not
found.” chapter of this manual. Use a torque wrench to tighten the lug nuts, use the crisscross star
pattern on page 42. If you do not have a torque wrench, use a lug wrench (from your tow vehicle) and
tighten the nuts as much as you can. At the first opportunity, have a service garage or trailer dealer
tighten the lug nuts to the proper torque.
^WARNING
Lug nuts are prone to loosen after initial installation, which can lead to death or serious injury.
Check lug nuts for tightness on a new trailer or when wheel(s) have been remounted after the
first 10, 25 and 50 miles of driving.
^WARNING
Improper lug nut torque can cause a wheel separating from the trailer, leading to death or
serious injury. Be sure lug nuts are tight before each tow.
1.2.9. INOPERABLE BRAKES,LIGHTS OR MIRRORS
Be sure that the electric brakes and all of the lights on your trailer are functioning properly before towing
your trailer. Electric brakes and lights on a trailer are controlled via a connection to the tow vehicle,
generally a multi-pin electrical connector. Check the trailer tail lights by turning on your tow vehicle
headlights. Check the trailer brake lights by having someone step on the tow vehicle brake pedal while
you look at trailer lights. Do the same thing to check the turn signal lights.
If your trailer has electric brakes, your tow vehicle will have an electric brake controller that sends power
to the trailer brakes. Before towing the trailer on the road, you must operate the brake controller while
trying to pull the trailer in order to confirm that the electric brakes operate. While towing the trailer at less
than 5 mph, manually operate the electric brake controller in the tow vehicle cab. You should feel the
operation of the trailer brakes.

General Safety Information
^WARNING
Improper electrical connection between the tow vehicle and the trailer will result in inoperable
lights and electric brakes, and can lead to collision.
Before each tow:
Check that the taillights, brake lights and turn signals work
Check that the electric brakes work by operating the brake controller inside the tow vehicle
1.2.10. HAZARDS FROM MODIFYING YOUR TRAILER
Essential safety items can be damaged by altering your trailer. Before making any alteration to your
trailer, contact your dealer or Bonnell Industries, Inc at 800-851-9664 and describe the alteration you are
contemplating. Alteration of the trailer structure or modification of mechanical, electrical, or other systems
on your trailer must be performed only by qualified technicians who are familiar with the system installed
on your trailer.
SAFETY WARNING LABELS ON YOUR TRAILER
Below are illustrations of the safety decals applied to your machine. Familiarize yourself with their
locations & importance. To protect you and others against death or serious injury, all of the labels shown
below must be on the trailer and must be legible. If any of these labels are missing or cannot be read,
call Bonnell Industries, Inc at 800-851-9664 for free replacement labels.
