Important Trailer Safety Information
Referencing the Utility Trailer in this
Manual
All references to the trailer or component parts to either
left or right are made with the assumption that you are
standing behind the trailer facing forward. Your left hand
or right hand is the equivalent on the trailer.
Tire Safety
The most common cause of trailer tire failure is under-
inflation. Therefore, it is important that you always
maintain the specified air pressure as indicated by the
tire manufacturer on the tire's side-walls. This informa-
tion can also be found on the tire label or the air pressure
molded on the tire side-wall.
The most important things you can do to maintaining
proper tire pressure are observe all tire and trailer
maximum carrying capacities, avoid road hazards, and
inspect the tires for cuts, slashes and other irregularities.
These practices, along with other care and maintenance,
can improve handling, help protect you and others from
avoidable breakdowns and accidents, improve fuel
economy, and increase the life of your tires.
Make tire safety a regular part of your trailer mainte-
nance routine. The time you spend is minimal compared
to the amount of time, inconvenience, and potential
safety hazards that can occur from a flat tire or failure.
Basic Tire Maintenance
Properly maintained tires improve the load-carrying
capability of your trailer. You can help avoid flat tires and
tire failures by maintaining proper tire pressure,
observing tire and trailer capacity limits, avoiding road
hazards, and inspecting your tires regularly.
Identifying Your Recommended Tire
Pressure and Maximum Load Carrying
Capacity for Your Trailer
Both the tire placard and the VIN label are permanently
attached on top of the frame of your trailer and have the
required information printed on them. They also list the
maximum load that can be placed on the trailer without
exceeding the load limits of the tires or the trailers other
components. These labels indicate the manufacturer’s
information including:
• Recommended tire size.
• Recommended tire inflation pressure.
• The maximum weight the trailer is designed to
carry.
• Gross vehicle weight rating of the trailer.
• Gross axle weight rating of the trailer.
Understanding Tire Pressure and Load
Limits
Tire inflation pressure is the level of air in the tire that
provides it with the load-carrying capacity and affects the
overall performance of the trailer. The tire inflation
pressure is a number that indicates the amount of air
pressure that is inside the tire. It is measured in pounds
per square inch (PSI). The tire must be inflated to the air
pressure as designated on the labels. Also listed on the
labels is the air pressure in kilo Pascals (kPa), which is a
metric measurement. Tire manufacturers determine the
air pressure to maximize the amount of weight the tires
can safely carry. The proper tire pressure for your trailer
tires is referred to as the “recommended cold inflation
pressure.” It is difficult to obtain the recommended tire
pressure if your tires are not cold when the reading is
taken because the air will expand when it is warmed by
towing down the road, thus increasing the air pressure
inside. If air is added to a tire that is low the air pressure
should never exceed the recommended pressure.
It is important to check your trailer’s tire pressure at least
once a month for the following reasons:
Most tires will naturally lose air over time.
Tires can lose air suddenly if driven over an object that
punctures or cuts the tire. Sometimes a sharp blow from
a pothole or curb can knock the tire loose from the rim
causing immediate deflation.
Maintaining Proper Tire Pressure
Locate the recommended tire pressure on the trailer's
tire information placard or owner's manual.
Record the tire pressure of all tires. If the tire pressure is
too high in any of the tires, slowly release air by gently
pressing on the tire valve stem with the edge of your tire
gauge until you get the correct pressure.
If the tire pressure is too low, note the difference between
the measured tire pressure and the correct tire pressure.
These “missing” pounds of pressure are what you will
need to add.
Add the missing pounds of air pressure to each tire that
is under inflated.
Check all tires to make sure they have the same air
pressure.
If you have been towing your trailer and think that a tire is
under inflated, fill it to the recommended cold inflation
pressure indicated on your trailer's tire label placard or
the VIN label. You can also check the sidewall of the tire
for a correct tire inflation pressure. Your tire will have a
slightly lower air pressure because the tire is warm when
you are inflating it, but it will be much better than to
continue to tow it with the under inflation it may have had.

Important Trailer Safety Information
Once the trailer has been parked long enough to allow
the tires to cool down, recheck the tire pressure and add
additional air to return the tire pressure to the recom-
mended level.
Tire Size
To maintain the trailer's carrying capacity and safety,
purchase only the same size tires as what were originally
supplied on the trailer.
Safety Tips
Slow down if you have to go over a pothole or other
object in road.
Do not run over curbs and try not to strike the curb when
parking.

IMPORTANT: Before towing this trailer be sure to
read the instructions and warnings supplied in this
manual. Also read the information supplied with
your tow vehicle so you know and understand its
limitations.
Never Tow the Trailer Before Checking:
• Coupler and latch assembly show no signs of
wear or damage.
• Coupler hitch and hitch ball are of the same size.
• Coupler and safety chains are safely secured to
the hitch.
• Check all fasteners for proper tightness.
• Load is securely tied down to the trailer.
• Wheel lug nuts are properly tightened to the right
torque.
• Wheel bearings are properly adjusted and main-
tained.
• Load is within the maximum load carrying
capacity of trailer.
• Tires are properly inflated and are road worthy.
• All trailer lighting is working properly.
• Tire pressure and tire condition
• Wheel lugs*
• Bearing lube and tightness
• Hitch
• Safety chains
• 12V running lights
• Distribution and security
• Caster up in travel position
* Check lug nuts for tightness before initial trip, at 10
miles, 25 miles and 50 miles. Recheck every 3 months or
3000 miles.
NOTE: Checking all of the above steps before
every trip is key for safety.
IMPORTANT: The load must be distributed equally
on the bed of the trailer if possible. Heavy, concen-
trated loads may cause damage or possible failure of
the trailer.
WARNING: Loads place on the trailer must be
securely tied to the trailer. Always use appropriate
tie downs designed to restrict loads from moving
when properly attached. Failure to do so will allow
shifting of the load causing potential trailer failure
and/or loss of the load and personal injury.
AVERTISSEMENT: Les charges placées sur la
remorque doivent être solidement attachées à la
remorque. Toujours utiliser des arrimages
appropriés conçus pour empêcher les charges de
bouger lorsqu'elles sont bien attachées. Le non-
respect de cette consigne permettra le mouvement
de la charge, entraînant une défaillance potentielle
de la remorque et/ou une perte de la charge et des
lésions corporelles.
This trailer is equipped to meet all applicable federal
safety standards in effect the day of manufacture. Check
local and state requirements regarding any additional
equipment that may be required.
The addition of optional equipment to your trailer may in-
crease the total weight of your trailer package to where it
now exceeds the maximum load carrying capacity of the
trailer.
Tow Vehicles
WARNING: Serious injury or property damage can
result if the total weight of your loaded trailer exceeds
the capacity of the hitch and/or your tow vehicle.
AVERTISSEMENT: Des blessures graves ou de
dommages à la propriété peuvent survenir sir le poids
total de la remorque chargée
excède la capacité de l'attelage et/ou du véhicule
remorqueur.
It is very important that you know and understand the
towing capabilities of your tow vehicle. This is especially
true with the braking abilities of the tow vehicle. You
should check with your authorized dealer to see what the
capabilities are for the total towing load and the maximum
allowable tongue weight for the vehicle you plan on using
for towing.
It is also important that the lighting system in the tow
vehicle has sufficient capacity support the additional load
the trailer lighting will add to the system. A heavy duty
flasher may be required to make your turn signals function
properly.

Important Trailer Safety Information
Trailer Ball & Couplers
WARNING: Failure to properly engage the hitch ball in
the coupler ball socket and securely lock the coupler
latch mechanism can cause the trailer to become
detached from the tow vehicle while traveling, which
may cause serious injury or property damage.
AVERTISSEMENT: Le non-respect d'engager
correctement la boule d'attache dans la cavité de la
boule de l'attelage et de verrouiller solidement le
mécanisme du loquet de l'attelage pourrait mener la
remorque à se détacher du véhicule remorqueur
pendant le déplacement, ce qui pourrait causer des
blessures graves ou des dommages à la propriété.
Ball diameter for which rating (GVWR) shall not exceed
the gross trailer weight marked on the trailer coupler.
The hitch balls have the rated load they are capable of
towing stamped Into the top of the ball.
Make sure the ball that you use to tow your trailer has the
same capacity rating as the coupler.
Do not use a different size ball than the size the coupler is
designed to use.
Before Towing:
Check mounting bracket hardware for wear and proper
tightness. Replace bent, broken, or worn hardware.
Tighten hardware to 75-94 ft. lbs. Use only the hardware
provided with the Trailer. If replacement hardware is
needed, order replacement kit 8.924-356.0.
Make sure that the trailer safety chains are properly
connected to the towing vehicle and trailer according to
SAE J684. See Safety Chain information in your manual.
Make sure that all trailer lighting is hooked up and working
properly.
Warning: Failure to follow all installation instructions
could result in coupler failure.
AVERTISSEMENT: Le non-respect de toutes les direc-
tives d'installation pourrait entraîner une panne du
coupleur.
Variable Height Bracket:
Coupler operation must not be impaired in any way. Do not
use if coupler operation is impaired.
Bolting Instructions:
Align holes in coupler and mounting bracket. NOTE:
Coupler must be secured to mounting bracket using two
sets of holes in the mounting bracket. Insert two (2) 5/
8”x4.5”, grade 5 bolts through desired mounting bracket
holes and coupler. For each bolt, Place one (1) washer at
the bolt head side and another at the bolt thread side
before assembling the nuts. Tighten lock nuts to 90-96 ft.
lbs. After installation, ensure coupler operation is not
impaired in any way. Do not use if coupler operation is
impaired. The hardware provided with the trailer has a
self-lubricating coating which is taken into account for the
tightening torque above, and is lower than standard
hardware and also is more consistent with re-torque spec-
ifications to first-torque than standard hardware. Order
replacements with the 8.924-356.0 replacement kit, or
consult your hardware vendor for applicable, higher,
torques for the application.
Maintenance
Keep ball pocket and mechanism clean. The following
procedures should be performed at least annually:
Check set screw torque Grease ball pocket
Oil pivot points with SAE 30 wt. motor oil
Inspect retaining pin and replace if necessary
Operation
To Couple:
1. Block trailer wheels.
2. Align hitch ball beneath coupler.
3. Open coupler locking lever. While holding locking
lever open, lower the coupler over the hitch ball until
ball is fully seated into the ball pocket.
4. If locking lever is pinned open, remove pin. Move
locking lever to the closed position. Check that the
latch is engaged by lifting up on back of locking lever.
Also, check that the hitch ball is fully seated and ball
clamp is below the ball. If the ball is not seated with
lever in the closed position and latch engaged, DO
NOT TOW.
Repeat the above steps.

To Uncouple:
1. Block trailer wheels.
2. Open locking lever. While holding locking lever fully
open, raise trailer off of hitch ball.
NOTE: A 5/16” diameter pin can be used to hold the
locking lever open.
Hitch Coupler Troubleshooting
If the coupler becomes damaged it must be repaired or
replaced before towing. When the coupler is placed on the
ball, the latch should close firmly. Keep the latch
mechanism lightly oiled and clean. Items to check for are
as follows:
1. Latch does not grasp ball securely:
• Check the ball size. Make sure the ball and
coupler are the same size.
2. Latch does not snap into full latch position:
• Check adjustment. Latch mechanism may be too
tight.
• Check to see that the coupler housing has not
been damaged, keeping the ball hitch from fitting
completely into the housing as designed.
3. Keep the tongue blocked up when not in use so the
coupler and mechanism are not in the ground being
exposed to dirt and moisture.
4. Apply a small amount of an automotive grease to the
ball before hitching coupler to prevent wear of the two
parts during towing.
5. Make sure the latch safety pin is in position before
towing.
Coupler & Ball Engagement
If the coupler and towing ball resist attempts to make
engagement, do not force latch assembly. Instead, check
the ball diameter to verify that it conforms to Society of
Automotive Engineers (SAE) specifications. Standard two-
inch diameter ball should be within the limits of 2.000-
inches to 1.970-inches. Balls larger than 2.000- inches will
not readily fit the coupler. A two-piece coupler ball is not
recommended.
If the coupler becomes damaged it must be repaired or
replaced before towing. When the coupler is placed on the
ball, the latch should close firmly. Keep the latch
mechanism lightly oiled and clean.
Improper engagement of the coupler and ball can cause
damage if the vehicles separate in transit, thus, caution
must be exercised to insure a secure hook-up. Lower the
coupler onto the ball with the coupler latch in the vertical
position. Continue to lower the trailer tongue until the jack
clears the ground, then flip the coupler latch to its locked
(horizontal) position. At this point visually observe that the
ball is fully engaged in the ball hitch. An even better check
to make sure the two are fully engaged is to raise the
tongue of the trailer again using the jack. Raise until the
ball hitch connection starts to raise the rear of the tow
vehicle. If the connection was not properly made, the ball
and socket will separate as the tongue of the trailer is
raised.
Safety Chains
Listed in the chart below are the different class sizes of
safety chains and the rated load each chain must be
capable of withstanding. Your trailer is equipped with
safety chains that meet the requirements of D.O.T Regula-
tion 393.70.
WARNING: Failure to properly attach safety chains
between the trailer and tow vehicle can result in a
runaway trailer.
AVERTISSEMENT: Le non-respect de fixer
correctement les chaînes de sécurité entre la
remorque et le véhicule remorqueur peut mener à
l'emballement de la remorque.
WARNING: To avoid accidents, before trailering:
AVERTISSEMENT: Pour éviter les accidents avant de
procéder à un remorquage
• Hitch only to ball size marked on coupling.
• Ball clamp must capture ball and lever or hand
wheel is fully clamped.
• Cross safety chains under coupling.
• Allow only enough slack for turns.

Important Trailer Safety Information
The safety chains on your trailer are an added
insurance that it will not become detached from the tow
vehicle. All safety chains are provided with an added
clasp to keep them from becoming accidentally
detached from the tow vehicle. Your trailer hitch on the
tow vehicle should have two attaching holes or rings for
attaching the safety chains, preferably one on each
side of the ball hitch. Crisscross the chains under the
tongue, the chain on the left side of the trailer tongue
attached to the right side of the ball hitch, the chain on
the right side of the trailer tongue attached to the left
side of the ball hitch.
This prevents the trailer tongue from dropping to the
road should the coupler or ball hitch fail. The chains
should be rigged as tight as possible with just enough
slack to allow tight turns to be made. This can be
accomplished by twisting the chain hook in a clockwise
or counterclockwise direction thus twisting the link
spacing and making the chain shorter. Also by keeping
your chains as short as possible you prevent them from
dragging on the road and wearing the chain links. If for
any reason you find it necessary to replace a safety
chain, use only original equipment.
Load-Carrying Capacity
Located on the front left-hand side of the frame, (either
the inside or the outside) is the VIN (Vehicle Identifica-
tion Number) tag. It will show the GVWR (Gross Vehicle
Weight Rating) which is the maximum load that can be
applied to the tires on the trailer. The GVWR and the
carrying capacity of the trailer are based on the tire size
installed on the trailer.
The GVWR is the maximum carrying capacity of the
trailer with its respective tires. It may not necessarily
equal the total GVWR of the trailer less the empty
weight of the trailer because there may be another
controlling factor such as frame strength that reduces
the carrying capacity to what is listed on the VIN tag.
The tire label will list the tire size that was installed on
the trailer as original equipment when it was sold to
you, the consumer. It also lists the maximum carrying
capacity of the trailer.
What To Check And How To Check
IMPORTANT: The total weight of the load must
never exceed the weight of cargo listed on the tire
label and/or the maximum load carrying capacity
listed on the VIN tag on your trailer. The GVWR
(Gross Vehicle Weight Rating) listed is the
maximum total weight of the trailer with accesso-
ries and all cargo allowable to be carried on the
tires that are installed on the trailer.
WARNING: Fishtailing caused from improper
tongue weight on the tow vehicle hitch ball can
cause loss of control of the tow vehicle and
resulting serious injury or property damage.
AVERTISSEMENT: Une embardée causée par un
poids de l'attelage inapproprié sur la boule
d'attache du véhicule remorqueur peut causer une
perte de contrôle du véhicule remorqueur et causer
des blessures graves et des dommages à la
propriété
CAUTION: The maximum load applied to the trailer
must never exceed the carrying capacity of the
trailer as stated on the VIN label and/or the tire
placard. Doing so may cause failure of one or more
component parts of the trailer causing potential
damage to the trailer and/ or a potential accident.
All concentrated loads must be spread over as
large an area as possible to eliminate potential
damage to the decking.
ATTENTION: La charge maximale appliquée à la
remorque ne doit jamais excéder la capacité de
charge de la remorque comme mentionné sur
l'étiquette NIV et/ou le flanc du pneu. Agir de la
sorte risquerait de causer une défaillance d'une ou
plusieurs composantes de la remorque, causant
des dommages potentiels à la remorque et/ou un
accident potentiel. Toutes les charges concentrées
doivent être réparties sur une surface aussi large
que possible pour éliminer tout dommage potentiel
au patio.
Shown on next page is an example of the tire label that
is placed on your trailer showing the items just
discussed above. Once you have familiarized yourself
with the information supplied on the example tire label
and VIN tag, check the tire size and capacity of your
trailer as shown on the VIN tag on your trailer.

What To Check And How To Check
Proper Weight Distribution & Tongue
Weight
Ensuring that your trailer has the proper GVWR is very
important. Once that has been established and you
have the load on the trailer it is equally important that
you have proper weight distribution.
Tongue Weight
The tongue weight on your trailer is 10%-15% of the
total weight of the trailer and all the cargo that it is
carrying. This is the amount of weight that is then trans-
ferred to the tow vehicle through the ball hitch.
Example: The total weight of the trailer with load is
2500 pounds. The tongue weight should not be less
than 250 pounds (10%).
Too light of tongue weight can cause the trailer to “fish-
tail” (sway Weight Rating) as you travel down the
highway. This creates excessive strains on the tow
vehicle, hitch and on the trailer itself. It can very easily
lead to an accident.
To adjust for too light of a tongue weight the load must
be shifted for-ward with respect to the axle. This will
increase the weight that is transferred to the tongue.
Adjustments should be made until the tongue weight
falls within 10% -15% recommended range. Likewise, if
you have too much tongue weight adjust the weight
backwards with respect to the axle until the tongue
weight falls in the recommended range
Tow vehicles vary on how much tongue weight they can
support for proper towing.
Tire Pressure
Proper air pressure for your tires is printed on the
sidewall. Check pressure while tires are cold. Do not
raise or lower pressure to meet load. Pressure other
than recommended pressure will lead to excessive tire
wear or tire failure. Balancing recommended.
Wheels
Check wheels for hole elongation or “out of round”. This
condition can be caused by lug nuts not being tight or
being too tight. Trailer wheels can be damaged by
chuck holes or curb jumping. You may not be aware of
the road shock to the wheels without periodic checks.
Replace any wheel that is bent. Replace any wheel if
you see elongation of the bolt holes.
Wheel Lugs
Wheel lug nuts must be tightened with a torque wrench.
Refer to the chart below for proper torque.
1. Start all bolts or nuts by hand to prevent cross
threading.
2. Tighten bolts or nuts following
sequence at right.
3. The tightening of the fasteners
should be done in stages.
Following the recommended
sequence, tighten fasteners
per wheel torque chart below.
4. Wheel nuts/bolts should be torqued before first
road use and after each wheel removal. Check and
re-torque after the first 10 miles, 25 miles and
again at 50 miles. Check periodically thereafter.

What To Check And How To Check
Ball Coupler Hitches
Coupler assembly includes a latch lever and latch lever
safety pin or hitch pin. Be sure the latch lever is locked
and the pin properly secured before moving your trailer.
The pin can be engaged fully only if ball is properly
seated in the coupler.
Tires
Before mounting tires onto wheels make certain that
the rim size and contour is approved for the tire as
shown in the Tire and Rim Association Yearbook or the
tire manufacturer’s catalog. Also make sure the tire will
carry the rated load. If the load is not equal on all tires
due to trailer weight distribution, use the tire rated for
the heaviest wheel position.
NOTE: The capacity rating molded into the sidewall
of the tire is not always the proper rating for the tire if
used in a trailer application. Use the following
guideline:
1. LT and ST tires: use the capacity rating molded into
the tire.
2. Passenger Car Tires: Use the capacity rating
molded into the tire sidewall divided by 1.10.
Use tire mounting procedures as outlined by the
Rubber Manufacturer’s Association or the tire manufac-
turers.
NOTE: Tire wear should be checked frequently
because once a wear pattern becomes firmly
established in a tire it is difficult to stop, even if the
underlying cause is corrected.

What To Check And How To Check
Breakaway Switch & D.O.T. Wet Cell
Battery
After hitching to the tow vehicle, pull the safety pin on
the breakaway switch. Check to see if system is opera-
tional. Push safety pin back in to its original position.
Check battery fluid level every 60-90 days. Remove
cover. There are two fill caps. Refill with distilled water
only.
Breakaway Switch Mounted on an A-
Frame
Attach breakaway switch cable securely in a straight
line to the tow vehicle. Locate attachments so little
“slack” is left in the cable, but enough slack to allow for
turning without disengaging the pin. The cable will
activate brakes the instant a trailer becomes disen-
gaged. Brake adjustment is critical to stopping a disen-
gaged trailer.
Check Breakaway System & Brakes Before
Each Trip
1. Disconnect 12V plug from tow vehicle.
2. Pull breakaway pin.
3. While pin is pulled, move tow vehicle forward.
Brake should be on and wheels locked.
4. Replace pin and secure to tow vehicle. Do not loop
over hitch ball.
5. Plug 12V connector into tow vehicle receptacle.
6. Test brakes with brake controller.
NOTE: When disconnecting trailer from tow vehicle,
make sure to replace safety pin.
Brakes
Your trailer is equipped with electric brakes.
Complete service and repair information for the electric
brakes is found in the Axle Break Service Manual that
is furnished with your trailer,
NOTE: It is important to strictly adhere to the axle break
instructions for brake service and repair. In this way, you
are protecting the validity of all applicable warranties.
Burnishing the Brakes
Brakes on a new trailer may tend to “grab” or pulsate.
This is normal. To correct the situation, pull the trailer
with the trailer brake control slightly engaged a short
distance (about 1000 ft or until trailer does not grab or
pull to one side anymore). This action smooths down
the brake bands.
NOTE: Do not lock up the wheels.
Reporting Safety Defects
If you believe that your trailer has a defect which could cause
a crash or could cause injury or death, you should immedi-
ately inform the National Highway Traffic Safety Administra-
tion (NHTSA) in addition to notifying Landa.
If NHTSA receives similar complaints, it may open an investi-
gation, and if it finds that a safety defect exists in a group of
trailers, it may order a recall and remedy campaign. However,
NHTSA cannot become involved in individual problems
between you, your dealer or Landa.
To contact NHTSA, you may either call the Auto Safety
Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153) or
write to:
