INSTALLATION
OUTDOOR INSTALLATION
Install the generator in a area that is free of debris,
bystanders, and overhead obstructions. Make sure the
generator is on secure level ground so that it cannot slide
or shift around. Also install the generator in a manner so
that the exhaust will not be discharged in the direction of
nearby homes.
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in shor t circuits and
grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
CAUTION
Pay close attention to ventilation when operating the
generator inside tunnels and caves. The engine exhaust
contains noxious elements. Engine exhaust must be
routed to a ventilated area.
GENERATOR GROUNDING
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground.
Article 250 (Grounding) of the National Electrical Code
(NEC) provides guidelines for proper grounding and
specifies that the cable ground shall be connected to the
grounding system of the building as close to the point of
cable entry as practical.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator to earth ground.
a. Copper - 10 AWG (5.3 mm2)
b. Aluminum - 8 AWG (8.4 mm2)
2. When grounding the generator (Figure 2) connect the
ground cable between the lock washer and the nut on
the generator and tighten the nut fully. Connect the
other end of the ground cable to earth ground.
INDOOR INSTALLATION
Exhaust gases from diesel engines are extremely
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
3. NEC article 250-52(c) specifies that the earth ground rod
should be buried a minimum of 8 ft. into the ground.
NOTICE
When connecting the generator to any buildings
electrical system ALWAYS consult with a licensed
electrician.
NOTICE
If connection of the ground rod is not feasible, please
check city, local or state electrical requirements on
generator grounding requirements.
SG1400C3 STUDIO GENERATOR • OPERATION AND PARTS MANUAL — REV. #1 (02/15/12) — PAGE 15
GENERAL INFORMATION
Generator
The MQ Power Model SG1400C3 is a 200kVA studio
generator that is designed as a high quality power source
for entertainment and studio applications.
In keeping with Multiquip's policy of constantly improving
its products, the specifications quoted herein are subject
to change without prior notice.
Permanent Magnet Generator Excitation System
The SG1400C3 generator is equipped with a PMG
(Permanent Magnet Generator) generator end. The
excitation system provides a minimum short circuit support
current of 300% of the standby rating for 10 seconds at 60
Hz, and approximately 275% at 50 Hz.
Both the PMG and the exciter are mounted outboard of the
bearing for ease of maintenance. The rotating brushless
exciter features hermetically sealed diodes for three-phase
full-wave rectification. The three-phase bridge is protected
against abnormal transient conditions by a multiplate
selenium surge protector.
Engine
shaft continues to rotate, the main rotor (field) induces a
voltage into the generator's main stator (armature). At rated
speed, the main stator's voltage produced by the residual
magnetism of the exciter allows the automatic voltage
regulator to function.
The regulator provides voltage to the exciter resulting in
a build-up of generator terminal voltage. This system of
using residual magnetism eliminates the need for a special
field flashing circuit in the regulator. After the generator
has established the initial residual voltage, the regulator
provides a controlled DC field voltage to the exciter stator
resulting in a controlled generator terminal voltage.
Voltage Regulation
In the standard configuration (shunt excited), the automatic
voltage regulator receives both its input power and voltage
sensing from the generator's output terminals. The regulator
automatically monitors the generator's output voltage
against an internal reference set point and provides the
necessary DC output voltage to the exciter field required
to maintain constant generator terminal voltage. The
generator's terminal voltage is changed by adjusting the
regulator's reference set point.
This generator is powered by a six-cylinder, 4-cycle direct
injection, turbocharged, air-cooled Cummins QSB7-G5
diesel engine. Engine speed is set at the factory at 1800
RPM. This engine is designed to meet every performance
requirement for the generator. Refer to Table 2 for engine
specifications.
Principle Of Operation
This generator is a brushless, self-excited, externally
voltage regulated, synchronous AC generator. The
generator is made up of six major components: main stator
(armature), main rotor (field), exciter stator (field), exciter
rotor (armature), rectifier assembly, and voltage regulator.
The generator's exciter consists of a stationary field and
a rotating armature. The stationary field (exciter stator)
is designed to be the primary source of the generator's
residual magnetism. This residual magnetism allows the
exciter rotor (armature) to produce AC voltage even when
the exciter stator (field) is not powered. This AC voltage
is rectified to DC by the rotating rectifier assembly and
fed directly to the main rotor (field). As the generator
Electronic Governor System
The electronic governor system controls the RPMs of the
engine. When the engine demand increases or decreases,
the governor system regulates the frequency variation to
± 0.25%.
Battery
The battery system is located in the engine compartment
on the sub-base. The battery’s primary purpose is to
provide starting power for the diesel engine starter motor.
The battery system is comprised of two 12 VDC, sealed
lead acid batteries wired in series to provide 24 VDC to
the starting motor. The battery is charged by the charging
alternator while the engine is engaged.
Exhaust System
The exhaust system is located above the diesel engine. The
exhaust system is comprised of rigid and flexible tubing, a
silencer, and a roof-mounted exhaust riser with a rain cap.

LOAD APPLICATION/GENERATOR OUTPUT
SINGLE PHASE LOAD
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage, frequency,
and voltage requirements are satisfactorily supplied by the
generator for operating the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require
130—150% more wattage than the rating on the nameplate,
as the wattage is influenced by the efficiency, power factor
and starting system of the equipment.
.
NOTICE
If wattage is not given on the equipment’s name plate,
approximate wattage may be determined by multiplying
nameplate voltage by the nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 1.0. See Table 7 below
when connecting loads.
Table 7. Power Factor By Load
Type of Load Power Factor
THREE PHASE LOAD
When calculating the power requirements for 3-phase
power use the following equation.
NOTICE
If 3Ø load (kVA) is not given on the equipment
nameplate, approximate 3Ø load may be determined
by multiplying voltage by amperage by 1.732.
NOTICE
Motors and motor-driven equipment draw much greater
current for starting than during operation.
An inadequate size connecting cable which cannot carry
the required load can cause a voltage drop which can burn
out the appliance or tool and overheat the cable. Refer to
Table 8 to select the correct cable size.
When connecting a resistance loa d such as an
incandescent lamp or electric heater, a capacity of up to
the generator’s rated output (kW) can be used.

INSPECTION/SETUP
BATTERY
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. DO NOT over fill. Battery life will be shortened if
the fluid level is not properly maintained. Add only distilled
water when replenishment is necessary.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunction. Always
keep the terminals firmly tightened. Coat the terminals with
an approved battery terminal treatment compound. Replace
battery with only recommended type battery.
The battery is sufficiently charged if the specific gravity
of the battery fluid is 1.28 (at 68° F). If the specific gravity
should fall to 1.245 or lower, the battery is dead and needs
to be recharged or replaced.
Before charging the battery with an external electric source,
be sure to disconnect the battery cables.
Battery Cable Installation
ALWAYS make sure that the battery cables (Figure 17) are
properly connected to the battery terminals as shown below.
CAUTION
When connecting the battery do the following:
1. Place a small amount of battery terminal treatment
compound around both battery terminals. This will
ensure a good connection and will help prevent
corrosion around the battery terminals.
2. Connect the red cable to the positive terminal of the
battery and the black cable to the negative terminal
of the battery.
.
NOTICE
If the battery cable is connected incorrectly, electrical
damage to the generator will occur. Pay close attention
to the polarity when connecting the battery.
CAUTION
Inadequate battery connections may cause poor
starting of the generator, and create other malfunctions.
ALTERNATOR
The polarity of the alternator is negative grounding type.
When an inverted circuit connection takes place, the circuit
will short instantaneously resulting in alternator failure.
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.
Figure 17. Battery Connections
DO NOT put water directly on the alternator. Water in the
alternator can cause corrosion and damage.
WIRING
Inspect the generator for bad, worn electrical wiring or
connections. If any wiring or connections are exposed
(insulation missing), replace wiring immediately.

PAGE 38 — SG1400C3 STUDIO GENERATOR • OPERATION AND PARTS MANUAL — REV. #1 (02/15/12)
MAINTENANCE
GENERAL INSPECTION
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts, and other fasteners. Also check for
fuel, oil, and coolant leaks. Use Table 14 as a general
maintenance guideline. For engine maintenance, refer to
the engine maintenance manual.
AIR FILTER
Every 250 hours: Remove air filter element (Figure 33) and
clean the filter element with low pressure compressed air.
Air pressure must not exceed 30 psi (207 kPa). The filter
can be cleaned and reused for up to six times if properly
cleaned. Replace air filter if rips or tears are detected while
cleaning.
Air Filter Dust Indicator
The air filter indicator (Figure 33) is attached to the air filter.
When the air filter element is clogged, air intake restriction
becomes greater and the air filter indicator signal shows
RED. When indicator is red, replace filter immediately. After
changing the air filter, press the air filter indicator button
to reset.
NOTICE
The air filter should be changed more frequently in
dusty operating conditions.
If the engine is operating in very dusty or dry grass
conditions, a clogged air cleaner will result. This can lead to
a loss of power, excessive carbon buildup in the combustion
chamber and high fuel consumption. Change air cleaner
more frequently if these conditions exist.
FUEL ADDITION
Add diesel fuel (the grade may vary according to season
and locations).
Removing Water from the Fuel Tank
After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally inspect the fuel tank
for water contamination and drain the contents if necessary.
During cold weather, the more empty volume inside the
tank, the easier it is for water to condense. This can be
reduced by keeping the tank full with diesel fuel.
Cleaning Inside the Fuel Tank

MAINTENANCE
FUEL TANK INSPECTION
In addition to cleaning the fuel tank, the following
components should be inspected for wear:
Rubber Suspension — look for signs of wear or
deformity due to contact with oil. Replace the rubber
suspension if necessary.
Fuel Hoses — inspect nylon and rubber hoses for signs
of wear, deterioration, and hardening.
Fuel Tank Lining — inspect the fuel tank lining for signs
of excessive amounts of oil and other foreign matter.
Replacing Fuel Filter
Replace the fuel filter cartridge with a new one every
500 hours.
Loosen the drain plug at the lower top of the fuel filter.
Drain the fuel in the fuel body together with the mixed
water. DO NOT spill the fuel during disassembly.
Vent any air.
AIR REMOVAL
If air enters the fuel injection system of a diesel engine,
starting becomes impossible. After running out of fuel, or
after disassembling the fuel system, bleed the system.
Refer to the Cummins engine manual for details.
FLUSHING OUT RADIATOR AND REPLACING

if necessary.
2. Completely drain the oil from the crankcase and refill,
if necessary, with fresh oil.
3. Clean the entire generator, inside and outside.
4. Disconnect the battery.
5. Make sure engine coolant is at proper level.
6. Cover the generator and store in a clean, and dry place.
MAINTENANCE
The following trailer maintenance guidelines are intended
to assist the operator in preventive maintenance.
TRAILER BRAKES
Properly functioning brake shoes and drums are essential
to ensure safety. The brakes should be inspected the first
200 miles of operation. This will allow the brake shoes and
drums to seat properly. After the first 200 mile interval,
inspect the brakes every 3,000 miles. If driving over rough
terrain, inspect the brakes more frequently.
HYDRAULIC BRAKES
If your trailer has hydraulic brakes, they function the same
way the surge brakes do on your tow vehicle. The hydraulic
braking system must be inspected at least as often as the
brakes on the tow vehicle, but no less than once per year.
This inspection includes an assessment of the condition
and proper operation of the wheel cylinders, brake shoes,
brake drums and hubs.
MANUALLY ADJUSTING THE BRAKES
6. Replace the adjusting-hole cover.
7. Repeat the above procedure on all brakes.
8. Lower the trailer to the ground.
Check the fluid level in the master cylinder reservoir at least
every three months. If you tow your trailer an average of
1,000 miles per month in a hot and dry environment, you
must check the brake fluid level once a month. The brake
fluid reservoir is located on the tongue of the trailer. Always
fill with clean, uncontaminated DOT 4 brake fluid.
Figure 35 below displays the major hydraulic brake
components that will require inspection and maintenance.
Please inspect these components as required using steps
1 through 6 as referenced in the “Manually Adjusting The
Brakes” section on this page. See Hydraulic Brake
Troubleshooting table in maintenance section.
Most axles are fitted with a brake mechanism that will adjust
the brakes during a hard stop. However, some braking
systems are not automatically adjusted by hard stopping.
These brakes require manual adjustment. The following
steps apply to adjust most manually adjustable brakes.
1. Jack up the trailer and secure it on adequate capacity
jackstands.
2. Be sure the wheel and brake drum rotate freely.
3. Remove the adjusting-hole cover from the adjusting
slot on the bottom of the brake backing plate.
4. With a screwdriver or standard adjusting tool, rotate the
starwheel of the adjuster assembly to expand the brake
shoes. Adjust the brake shoes out until the pressure
of the linings against the drum makes the wheel very
difficult to turn. Note: Your trailer maybe equipped with
drop spindle axles. See axle manual for your axle type.
You will need a modified adjusting tool for adjusting
the brakes in these axles. With drop spindle axles, a
modified adjusting tool with about an 80 degree angle
should be used.
Figure 35. Hydraulic Brake Components
HYDRAULIC BRAKE ACTUATOR
The hydraulic brake actuator (Figure 36) is the mechanism
that activates the trailer’s brake system. This actuator
changes fluid power into mechanical power. Therefore, the
fluid level must be checked frequently to assure that the
brakes function properly.
HYDRAULIC
BRAKE FLUID
RESERVOIR
5. Rotate the starwheel in the opposite direction until the
wheel turns freely with a slight drag.
Figure 36. Hydraulic Brake Actuator
SG1400C3 STUDIO GENERATOR • OPERATION AND PARTS MANUAL — REV. #1 (02/15/12) — PAGE 41
WARNING
Failure to maintain proper fluid level in the actuator
may result in loss of braking action which could cause
severe property damage, injury or death.
Periodically check the actuator mounting fasteners for
damage or loosening. Inspect the actuator for worn or
damaged parts. As you are towing your trailer, be aware
of any changes in braking quality. This could be an early
warning of brake or actuator malfunction and requires
immediate attention. Consult a certified brake specialist to
make necessary adjustment or repairs.

(Figure 3) that allows the coupler to be raised or lowered
to a desired height. Periodically check the channel bolts for
damage or loosening.
NOTICE
When replacing channel mounting hardware (nuts,
bolts and washers), NEVER substitute substandard
hardware. Pay close attention to bolt length and grade.
ALWAYS use manufacturer's recommended parts
when replacing channel mounting hardware.
MAINTENANCE
Figure 37. Adjustable Channel
WHEEL BEARINGS
Wheel bearings (Figure 38) must be inspected and
lubricated once a year or 12,000 miles to insure safe
operation of your trailer.
If trailer wheel bearings are immersed in water, they must
be replaced.
DANGER
If trailer wheels are under water for a long period of
time, wheel bearings may fail. If this is the case, service
wheel bearings immediately.
The possibility exists of the wheels falling off causing
equipment damage and severe bodily harm even death!
If the trailer has not been used for an extended amount
of time, have the bearings inspected and packed more
frequently, at least every six months and prior to use.
Follow the steps below to disassemble the wheel hub and
service the wheel bearings. See Figure 38.

Every time the wheel hub is removed and the bearings are
reassembled, follow the steps below to check the wheel
bearings for free running and adjust.
Turn the hub slowly, by hand, while tightening the spindle
nut until you can no longer turn the hub by hand.
Loosen the spindle nut just until you are able to turn it
(the spindle nut) by hand. Do not turn the hub while the
spindle nut is loose.
DANGER
Improper weld repair will lead to early failure of the
trailer structure and can cause serious injury or death.
DO NOT repair cracked or broken welds unless you
have a certified welder perform the repair. If not, have
the welds repaired by your dealer.
WARNING
If the trailer is involved in an accident, have it inspected
immediately by qualified personnel. In addition, the
trailer should be inspected annually for signs of wear
or deformations.
LEAF SUSPENSION
The leaf suspension springs and associated components
(Figure 39) should be visually inspected every 6,000 miles
for signs of excessive wear, elongation of bolt holes, and
loosening of fasteners. Replace all damaged par ts
(suspension) immediately.
Install a new cotter pin through the spindle nut and axle.
Check the adjustments. Both the hub and the spindle nut
should be able to move freely (the spindle nut motion
will be limited by the cotter pin).
DANGER
NEVER crawl under the trailer unless it is on firm
and level ground and resting on properly placed and
secured jackstands.
The possibility exists of the trailer falling thus causing
equipment damage and severe bodily harm even death!
DANGER
When performing trailer inspection and maintenance
activities, you must jack up the trailer using jacks and
jackstands.
When jacking and using jackstands, place them so
as to clear wiring, brake lines, and suspension parts
(i.e., springs, torsion bars). Place jacks and jackstands
inside of the perimeter strip on the supporting structure
to which the axles are attached.

to pass, due to slower acceleration and increased length.
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.
Check rearview mirrors frequently to observe the trailer
and traffi c.
NEVER drive faster than what is safe.

vehicle are rated for the Gross Vehicle Weight Rating of
your trailer.
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.
• 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.
Follow all of the safety precautions and instructions in
this manual to ensure safety of persons, equipment, and
satisfactory life of the trailer. Always use an adequate tow
vehicle and hitch. If the vehicle or hitch is not properly
selected and matched to the Gross Vehicle Weight Rating
(GVWR) of your trailer, you can cause an accident that
could lead to death or serious injury.
If you already have a tow vehicle, know your vehicle tow
rating and make certain the trailer’s rated capacity is less
than or equal to the tow vehicle’s rated towing capacity. If
you already have (or plan to buy) a trailer, make certain
that the tow rating of the tow vehicle is equal to or greater
than that of the trailer.

Be sure that the brakes and all of the lights on your trailer
are functioning properly before towing your trailer. Check

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. See Trailer
Wiring Diagram section in this manual.
Standard mirrors usually do not provide adequate visibility
for viewing traffi c to the sides and rear of a towed trailer.
You must provide mirrors that allow you to safely observe
approaching traffi c.
WARNING
Improper electrical connection between the tow vehicle
and the trailer will result in inoperable lights and can
lead to collision.
Before each tow, check that the tail lights, brake lights
and turn signals work.
TRAILER TOWING TIPS
Driving a vehicle with a trailer in tow is vastly different
from driving the same vehicle without a trailer in tow.
Acceleration, maneuverability and braking are all diminished
with a trailer in tow.
It takes longer to get up to speed, you need more room to
turn and pass, and more distance to stop when towing a
trailer. You will need to spend time adjusting to the different
feel and maneuverability of the tow vehicle with a loaded
trailer.
Because of the signifi cant differences in all aspects of
maneuverability when towing a trailer, the hazards and risks
of injury are also much greater than when driving without
a trailer. You are responsible for keeping your vehicle and
trailer in control, and for all the damage that is caused if
you lose control of your vehicle and trailer.
As you did when learning to drive an automobile, fi nd
an open area with little or no traffi c for your fi rst practice
trailering. Of course, before you start towing the trailer, you
must follow all of the instructions for inspection, testing,
loading and coupling. Also, before you start towing, adjust
the mirrors so you can see the trailer as well as the area
to the rear of it.
responds. Next, make some right and left hand turns.
Watch in your side mirrors to see how the trailer follows
the tow vehicle. Turning with a trailer attached requires
more room.

It is wise to carry these warning devices even if you are
not towing a trailer. It is particularly important to have these
when towing a trailer because the hazard fl ashers of your
towing vehicle will not operate for as long a period of time
when the battery is running both the trailer lights and tow
vehicle lights.
SAFETY CHAINS
If the coupler connection comes loose, the safety chains
can keep the trailer attached to the tow vehicle. With
properly rigged safety chains, it is possible to keep the
tongue of the trailer from digging into the road pavement,
even if the coupler-to-hitch connection comes apart.

A device that connects electrical power from the tow vehicle
to the trailer. Electricity is used to turn on brake lights,
running lights, and turn signals as required. In addition, if
your trailer has a separate braking system, the electrical
connector will also supply power to the brakes from the
tow vehicle.

If the trailer coupler connection comes loose, the breakaway
system can actuate emergency hydraulic brakes depending
on the type of actuator on the trailer. The breakaway cable
must be rigged to the tow vehicle with appropriate slack
that will activate the system if the coupler connection
comes loose.

and wheels because they carry a heavier load. Therefore,
it is essential to inspect the trailer tires before each tow.
If a tire has a bald spot, bulge, cuts, is showing any cords,
or is cracked, 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 infl ation.
Tires with too little tread will not provide adequate tracking
on wet roadways and can result in loss of control, leading
to death or serious injury.
Improper tire pressure causes an unstable trailer and
can result in a tire blowout and loss of control. Therefore,
before each tow you must also check the tire pressure. Tire
pressure must 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. Trailer tires will be
infl ated to higher pressures than passenger vehicle tires.
Since trailer wheels and lug nuts (or bolts) are subjected
to greater side loads than automobile wheels, they are
more prone to loosen. Before each tow, check to make
sure they are tight.

The proper tightness (torque) for lug nuts is listed in the
lug nut tightening section of this manual. Use a torque
wrench to tighten the lug nuts. 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. Then have a service
garage or trailer dealer tighten the lug nuts to the proper
torque.
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.

If additional work items (hoses, tools, clamps etc.) are
going to be added to the trailer, be sure they are distributed
evenly to prevent overloading front to back and side to side.
Heavy items should be placed low and as close to the axle
positions as reasonable. Too many items on one side may
overload a tire.
Excessive loads and/or underinfl ation cause tire overloading
and, as a result, abnormal tire fl exing occurs. This situation
can generate an excessive amount of heat within the tire.
Excessive heat may lead to tire failure. It is the air pressure
that enables a tire to support the load, so proper infl ation
is critical. The proper air pressure may be found on the
certifi cation/VIN label and/or on the Tire and Loading
Information placard. This value should never exceed the
maximum cold infl ation pressure stamped on the tire.
Perform the following steps to determine the load limit of
your trailer.
Step 1.
Locate the statement, “The weight of cargo should never
exceed XXX kg or XXX lbs.,” on your vehicle’s Tire and
Loading Information placard (Figure I). This value equals
the available amount of equipment load capacity.
Step 2.
Determine the weight of the equipment being loaded
on the tow vehicle. That weight may not safely exceed
the available equipment load capacity. The trailer’s Tire
Information Placard is attached adjacent to or near the

TIRE FUNDAMENTALS
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires (Figure J). This
information identifies and describes the fundamental
characteristics of the tire and also provides a tire
identifi cation number for safety standard certifi cation and
in case of a recall.
Figure J. Standard Tire Sidewall Information
P: The “P” indicates the tire is for passenger vehicles.
Next number: This three-digit number gives the width in
millimeters of the tire from sidewall edge to sidewall edge.
In general, the larger the number, the wider the tire.
Next number: This two-digit number, known as the aspect
ratio, gives the tire’s ratio of height to width. Numbers of
70 or lower indicate a short sidewall for improved steering
response and better overall handling on dry pavement.
P: The “R” stands for radial. Radial ply construction of tires
has been the industry standard for the past 20 years.
Next number: This two-digit number is the wheel or rim
diameter in inches. If you change your wheel size, you
will have to purchase new tires to match the new wheel
diameter.
Next number: This two- or three-digit number is the tire’s
load index. It is a measurement of how much weight each
tire can support. You may fi nd this information in your
owner’s manual. If not, contact a local tire dealer. Note:
You may not fi nd this information on all tires because it is

Wheel Rims
If the trailer has been struck, or impacted, on or near the
wheels, or if the trailer has struck a curb, inspect the rims for
damage (i.e. being out of round); and replace any damaged
wheel. Inspect the wheels for damage every year, even if
no obvious impact has occurred.
Wheels, Bearings and Lug Nuts
A loose, worn or damaged wheel bearing is the most
common cause of brakes that grab.
To check wheel bearings, jack trailer and check wheels
for side-to-side looseness. If the wheels are loose, or spin
