Safety Information
engine saFeTY
danger
The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.
The engine of this equipment
requires an adequate free
flow of cooling air. never
operate this equipment in
any enclosed or narrow area
where free flow of the air is
restricted. If the air flow is
restricted it will cause injury to people and property and
serious damage to the equipment or engine.
Warning
do noT place hands or fingers inside engine
compartment when engine is running.
never operate the engine with heat shields or
guards removed.
Keep fingers, hands hair and clothing away
from all moving parts to prevent injury.
do noT remove the radiator cap while the
engine is hot. High pressure boiling water
will gush out of the radiator and severely
scald any persons in the general area of
the generator.
do noT remove the coolant drain plug while the engine
is hot. Hot coolant will gush out of the coolant tank and
severely scald any persons in the general area of the
generator.
do noT remove the engine oil drain plug while the
engine is hot. Hot oil will gush out of the oil tank and
severely scald any persons in the general area of the
generator.
cauTion
never touch the hot exhaust manifold,
muffler or cylinder. Allow these parts to cool
before servicing equipment.

NOTICE
never run engine without an air filter or with a dirty air
filter. Severe engine damage may occur. Service air filter
frequently to prevent engine malfunction.
never tamper with the factory settings
of the engine or engine governor. Damage
to the engine or equipment can result
if operating in speed ranges above the
maximum allowable.
Wet stacking is a common problem with diesel engines
which are operated for extended periods with light or
no load applied. When a diesel engine operates without
sufficient load (less than 40% of the rated output), it will
not operate at its optimum temperature. This will allow
unburned fuel to accumulate in the exhaust system,
which can foul the fuel injectors, engine valves and
exhaust system, including turbochargers, and reduce
the operating performance.
In order for a diesel engine to operate at peak efficiency,
it must be able to provide fuel and air in the proper ratio
and at a high enough engine temperature for the engine
to completely burn all of the fuel.
Wet stacking does not usually cause any permanent
damage and can be alleviated if additional load is
applied to relieve the condition. It can reduce the system
performance and increase maintenance. Applying an
increasing load over a period of time until the excess
fuel is burned off and the system capacity is reached
usually can repair the condition. This can take several
hours to burn off the accumulated unburned fuel.
State Health Safety Codes and Public Resources
Codes specify that in certain locations, spark arresters
must be used on internal combustion engines that use
hydrocarbon fuels. A spark arrester is a device designed
to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified
and rated by the United States Forest Service for this
purpose. In order to comply with local laws regarding
spark arresters, consult the engine distributor or the
local Health and Safety Administrator.

Installation
Outdoor Installation

Generator Grounding

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.

To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground (Figure 2).

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 short 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.

Indoor Installation

Article 250 (Grounding) of the National Electrical Code
(NEC) provides guide lines 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 - 8 AWG (5.3 mm2)
b. Aluminum - 6 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.
3. NEC article 250-52(c) specifies that the earth ground rod
should be buried a minimum of 8 ft. into the ground.

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.

When connecting the generator to any buildings
electrical system ALWAYS consult with a licensed
electrician.

Mounting

This generator has a permanent bonding conductor
between the generator stator windings and the frame.

NOTICE

The generator must be mounted on a solid foundation (such
as concrete) and set firmly on the foundation to isolate
vibration of the generator when it is running. The generator
must set at least 6 inches above the floor or grade level (in
accordance to NFPA 110, Chapter 5-4.1). DO NOT remove
the metal skids on the bottom of the generator. They are
to resist damage to the bottom of the generator and to
maintain alignment.

General Information
Generator

Open Delta Excitation System

This generator (Figure 3) is designed as a high quality
portable (requires a trailer for transport) power source for
telecom sites, lighting facilities, power tools, submersible
pumps and other industrial and construction machinery.

Each generator is equipped with the state of the art “OpenDelta” excitation system. The open delta system consist
of an electrically independent winding wound among
stationary windings of the AC output section.
There are four connections of the open delta A, B, C and
D. During steady state loads, the power from the voltage
regulator is supplied from the parallel connections of A to
B, A to D, and C to D. These three phases of the voltage
input to the voltage regulator are then rectified and are the
excitation current for the exciter section.
When a heavy load, such as a motor starting or a short
circuit occurs, the automatic voltage regulator (AVR)
switches the configuration of the open delta to the series
connection of B to C. This has the effect of adding the
voltages of each phase to provide higher excitation to the
exciter section and thus better voltage response during the
application of heavy loads.
The connections of the AVR to the AC output windings are
for sensing only. No power is required from these windings.
The open-delta design provides virtually unlimited excitation
current, offering maximum motor starting capabilities. The
excitation does not have a “fixed ceiling” and responds
according the demands of the required load.

Engine
This generator is powered by a 6 cylinder, 4-cycle water
cooled, direct injection, turbocharged, air cooled Cummins
qsb7-g6 diesel engine. This engine is designed to
meet every performance requirement for the generator.
Reference Table 2 for engine specifications.
In keeping with MQ Power’s policy of constantly improving
its products, the specifications quoted herein are subject
to change without prior notice.

Electric Governor System
The electric governor system controls the RPMs of the engine.
When the engine demand increases or decreases, the
governor system regulates the frequency variation to ±.25%.

Extension Cables
When electric power is to be provided to various tools or
loads at some distance from the generator, extension cords
are normally used. Cables should be sized to allow for
distance in length and amperage so that the voltage drop
between the generator and point of use (load) is held to
a minimum. Use the cable selection chart (Table 6) as a
guide for selecting proper extension cable size.

Load Application
Single Phase Load

Three 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.

When calculating the power requirements for 3-phase
power use the following equation:

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 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
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 0.8. See Table 5 below
when connecting loads.

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. See Table 6.
When connecting a resistance load such as an
incandescent lamp or electric heater, a capacity of up
to the generating set’s rated output (kW) can be used.
When connecting a fluorescent or mercury lamp, a
capacity of up to the generating set’s rated output (kW)
multiplied by 0.6 can be used.
When connecting an electric drill or other power tools,
pay close attention to the required starting current
capacity.

Coolant (Antifreeze/Summer Coolant/
Water)
Cummins recommends antifreeze/summer coolant for use in
their engines, which can be purchased in concentrate (and
mixed with 50% demineralized water) or pre-diluted. See the
Cummins Engine Owner’s Manual for further details.

Cleaning the Radiator
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the
radiator fins with compressed air. Cleaning inside the
machine is dangerous, so clean only with the engine turned
off and the negative battery terminal disconnected.

Air Cleaner

WARNING
If adding coolant/antifreeze mix to the
radiator, DO NOT remove the radiator cap
until the unit has completely cooled. The
possibility of hot! coolant exists which can
cause severe burns.
Day-to-day addition of coolant is done from the recovery
tank. When adding coolant to the radiator, DO NOT remove
the radiator cap until the unit has completely cooled. See
Table 10 for engine, radiator, and recovery tank coolant
capacities. Make sure the coolant level in the recovery tank
is always between the “H” and the “L” markings.

Periodic cleaning/replacement is necessary. Inspect air
cleaner in accordance with the Cummins Engine Owner’s
Manual.

Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the
Cummins Engine Owner’s Manual.
The fan belt tension is proper if the fan belt bends 10 to 15
mm (Figure 33) when depressed with the thumb as shown

Battery

When connecting battery do the following:

This unit is of negative ground DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level are
not properly maintained. Add only distilled water when
replenishment is necessary.

1. NEVER connect the battery cables to the battery
terminals when the Auto-Off/Reset-Manual Switch
is in either the AUTO or MANUAL position. ALWAYS
make sure that this switch is in the OFF/RESET
position when connecting the battery.

DO NOT over fill. Check to see whether the battery
cables are loose. Poor contact may result in poor starting
or malfunctions. Always keep the terminals firmly
tightened. Coating the terminals with an approved battery
terminal treatment compound. Replace battery with only
recommended type battery. The battery type used in this
generator is BCI Group 27.

2. 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.

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, it indicates that 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 be sure the battery cables (Figure 34) are properly
connected to the battery terminals as shown below. The
red cable is connected to the positive terminal of the
battery, and the black cable is connected to the negative
terminal of the battery.
CAUTION
ALWAYS disconnect the negative terminal FIRST and
reconnect negative terminal LAST.

NOTICE
If the battery cable is connected incorrectly, electrical
damage to the generator will occur. Pay close attention
to the polarity of the battery 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

General Inspection
Prior to each use, the generator should be cleaned and
inspected for deficiencies. Check for loose, missing or
damaged nuts, bolts or other fasteners. Also check for
fuel, oil, and coolant leaks. Use Table 12 as a general
maintenance guideline Engine Side (Refer to the Engine
Instruction Manual)

Air Cleaner
Every 250 hours: Remove air cleaner element (Figure 55)
and clean the heavy duty paper element with light spray of
compressed air. Replace the air cleaner as needed.

Air Cleaner with Dust Indicator
This indicator () is attached to the air cleaner. When the air
cleaner element is clogged, air intake restriction becomes
greater and the dust indicator signal shows RED meaning
the element needs changing or service. After changing
the air element, press the dust indicator button to reset
the indicator.

Figure 55. Air Cleaner/Indicator

NOTICE
The air filter should not be changed until the indicator
reads “RED”. Dispose of old air filter. It may not be
cleaned or reused..

page 36 — dca220sscu/4i 60 hz generator • operation and Parts manual — rev. #0 (10/25/12)

Maintenance
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 exists.

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 required.
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
Drain the fuel inside the fuel tank completely. Using a spray
washer (Figure 56) wash out any deposits or debris that
have accumulated inside the fuel tank.

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 or other foreign matter.

Replacing Fuel Filter
Replace the fuel filter cartridge with new one every 500
hours or so.
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
according to the following procedure. See the Cummins
Engine Manual for details.

Figure 56. Fuel Tank Cleaning

DCA220ssCU/4i 60 hz generator• operation manual — rev. #0 (10/25/12) — page 37

Maintenance
To restart after running out of fuel, turn the switch to the
“ON” position for 15-30 seconds. Try again, if needed. This
unit is equipped with an automatic air bleeding system.

Check Oil Level
Check the crankcase oil level prior to each use, or when the
fuel tank is filled. Insufficient oil may cause severe damage
to the engine. Make sure the generator is level. The oil
level must be between the two notches on the dipstick as
shown in Figure 27.

Radiator Cleaning
The radiator (Figure 57) should be sprayed (cleaned) with
a high pressure washer when excessive amounts of dirt
and debris have accumulated on the cooling fins or tube.
When using a high pressure washer, stand at least 5 feet
(1.5 meters) away from the radiator to prevent damage to
the fins and tube.

Replacing Oil Filter
Remove the old oil filter.
Apply a film of oil to the gasket on the new oil filter.
Install the new oil filter.
After the oil cartridge has been replaced, the engine oil
will drop slightly. Run the engine for a while and check for
leaks before adding more oil if needed. Clean excessive
oil from engine.

Flushing Out Radiator and Replacing
Coolant
Open both cocks located at the crankcase side and at
the lower part of the radiator and drain coolant. Open
the radiator cap while draining. Remove the overflow
tank and drain.

Figure 57. Radiator Cleaning

Generator Storage
For long term storage of the generator the following is
recommended:
Drain the fuel tank completely. Treat with a fuel stabilizer
if necessary.

Check hoses for softening and kinks. Check clamps for
signs of leakage.

Completely drain the oil from the crankcase and refill if
necessary with fresh oil.

Tighten both cocks and replace the overflow tank.

Clean the entire generator, internal and external.

Replace with coolant as recommended by the engine
manufacturer.

Cover the generating set and store in a clean, dry place.

Close radiator cap tightly.
Flush the radiator by running clean tap water through
radiator until signs of rust and dirt are removed. DO
NOT clean radiator core with any objects, such as a
screwdriver.

Disconnect the battery.
Make sure engine coolant is at proper level.
If generator is mounted on a trailer, jack trailer up and
place on blocks so tires do not touch the ground or block
and completely remove the tires.

WARNING
Allow engine to cool when flushing out
radiator. Flushing the radiator while hot
could cause serious burns from water or
steam.

Maintenance
Jacket Water Heater and Internal Battery
Charger 120 VAC Input Receptacles
(OPTIONAL)
This generator can be optionally equipped with two 120
VAC, 20 amp input receptacles located on the output
terminal panel.
The purpose of these receptacles is to provide power via
commercial power to the jacket water heater and internal
battery charger.

If the generator will be used daily, the battery should
normally not require charging. If the generator will be idle
(not used) for long periods of time, apply power to the
battery charger receptacle via commercial power using a
power cord of adequate size.
NOTICE
To ensure adequate starting capability, always have
power applied to the generator's internal battery
charger..

These receptacles will ONLY function when commercial
power has been supplied to them (Figure 58). To apply
commercial power to these receptacles, a power cord of
adequate size will be required (See Table 6).
When using the generator in hot climates there is no reason
to apply power to jacket water heater. However, if the
generator will be used in cold climates it is always a good
idea to apply power to the jacket water heater at all times.
To apply power to the jacket water heater simply apply
power to the jacket water heater receptacle via commercial
power using an power cord of adequate size.

Maintenance
Emission control
The emission control system employed with the Cummins
QSB&-G6 diesel engine consist of a Diesel Oxidation
Catalyst (DOC) and a Diesel Particulate Filter (DPF). The
oxidation catalyst and particulate filter are housed in one
unit. See Figure 61.
These devices help in filtering out large amounts of harmful
Nitrogen Oxides (NOx) and Particulate Matter (PM) which
are emitted by diesel engines. These exhaust emissions
pose serious environmental and health risks. It is important
to maintain and service this DOC/DPF emission safety
device on a periodic basis.

Diesel Oxidation Catalyst (DOC)
The DOC does not filter particles it oxidizes them. This
catalyst (honeycomb like structure) uses a chemical
process to break down pollutants in the exhaust stream
into less harmful components. In general this catalyst
collects/burns accumulated particulates. The DOC contains
palladium and platinum which serve as a catalysts to oxidize
hydrocarbons and carbon monoxide.

Forced (Stationary) Regeneration — A forced
regeneration only occurs when the operator has initiated
this action at the ECU and the ECM recognizes a preprogrammed set point of soot in the PDF to allow a forced
regeneration cycle.
This process can take anywhere from 30 minutes to
1-1/2 hours. When forced regeneration is in process all
loads must be removed from the generator, all circuit
breakers must be placed in the OFF position (OPEN),
and the engine speed set to idle.

DPF pre-alarm
In the event the Engine Control Unit (ECU) determines
the soot level back pressure and/or tempertaure has
reached a pre-determined trip point the ECU will indicate
a maintenance action is required by the operator.
This maintenance action will be shown on the LCD display
(DPF Warning Symbol) and the AMBER pre-alarm LED on
the ECU control panel will be ON (lit). See Figure 59.

ECU

Series 800 Controller

Diesel Particulate Filter (DPF)

Engine Started

DPF STAT

A diesel particulate filter (DPF) is a device designed to
remove diesel particulate matter (soot) from the exhaust
gas of a diesel engine. This type of filter usually removes
about 85-95% of the soot.
Soot accumulated in the DPF is removed via the
"regeneration process". Regeneration is the process
of removing the accumulated soot from the filter. This
regeneration process can occur in a few different ways.
Passive Regeneration — Occurs during normal
operation, typically under heavy load applications. Soot
is oxidized faster than it is collected.
Active Regeneration — Occurs when engine exhaust
temperatures are not high enough to oxidize the soot
collected in the DPF. Active regeneration requires
assistance from the engine to help increase the heat
level in the after-treatment system.
Active regeneration occurs at a normal engine speed
of 1800 rpm. In addition active regeneration is initiated
automatically by the Engine Control Module (ECM) timer
based program every 96 hours. This timer base program
will reset at the end of any regeneration mode.

damage to the equipment.
The definitions below describe some of the major
components of a typical trailer that would be used with
the generator.
1. Fuel Cell — Provides an adequate amount of fuel for
the equipment in use. Fuel cells must be empty when
transporting equipment.
2. Braking System — System employed in stopping
the trailer. Typical braking systems are electric, surge,
hydraulic, hydraulic-surge and air.
3. GVWR — Gross Vehicle Weight Rating (GVWR) is
the maximum number of pounds the trailer can carry,
including the fuel cell (empty).
4. Frame Length — Measurement is from the ball hitch
to the rear bumper (reflector).
5. Frame Width — Measurement is from fender to fender
6. Jack Stand — Trailer support device with maximum
pound requirement from the tongue of the trailer.
7. Coupler — Type of hitch used on the trailer for towing.

8. Tire Size — Indicates the diameter of the tire in
inches (10,12,14, etc.), and the width in millimeters
(175,185,205, etc.). The tire diameter must match the
diameter of the tire rim.
9. Tire Ply — The tire ply (layers) number is rated in
letters; 2-ply,4-ply,6-ply, etc.
10. Wheel Hub — The wheel hub is connected to the
trailer’s axle.
11. Tire Rim — Tires mounted on a tire rim. The tire rim
must match the size of the tire.
12. Lug Nuts — Used to secure the wheel to the wheel
hub. Always use a torque wrench to tighten down
the lug nuts. See Table 16 and Figure 62 for lug nut
tightening and sequence.
13. Axle — Indicates the maximum weight the axle can
support in pounds, and the diameter of the axle
expressed in inches. Please note that some trailers
have a double axle. This will be shown as 2-6000 lbs.,
meaning two axles with a total weight capacity of 6000
pounds.
14. Suspension — Protects the trailer chassis from shocks
transmitted through the wheels. Types of suspension
used are leaf, Q-flex, and air ride.
15. Electrical — Electrical connectors (looms) are
provided with the trailer so the brake lights and turn
signals can be connected to the towing vehicle.

Trailer Maintenance
Brakes

Hydraulic Surge Brakes

Trailer 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.
Figure 62 displays the major hydraulic surge brake
components that will require inspection and maintenance.
Please inspect these components as required using steps
1 through 8 and Table 13 as listed below:

Hydraulic surge brakes (Figure 62) should not require any
special attention with the exception of routine maintenance
such as shoe and lining replacement. Brake lines should
be periodically checked for cracks, kinks, or blockage.

Brake Adjustment
1. Place the trailer on jack stands. Make sure the jack
stands are placed on secure level ground.
2. Check the wheel and drum for free rotation.
3. Remove the adjusting hole cover from the adjusting
slot at the bottom brake backing plate.
4. With a screwdriver or standard adjusting tool, rotate
the star wheel of the adjuster assembly to expand the
brake shoes.
5. Adjust the brake shoes outward until the pressure of
the lining against the wheel drum makes the wheel
difficult to turn.
6. Adjust, rotate the star wheel in the opposite direction
until the wheel rotates freely with slight lining drag.
7. Replace the adjusting hole cover and lower the trailer
to the ground.
8. Repeat steps 1 through 7 on the remaining brakes.

Figure 62. Hydraulic Brake Components

Actuator
Hydraulic surge braking requires the installation of an
actuator at the tongue of the trailer. Remember the surge
or push of the trailer toward the tow vehicle automatically
synchronizes the trailer brakes with the tow vehicle brakes.
As the trailer pushes against the tow vehicle the actuator
telescopes together and applies force to the master
cylinder, supplying hydraulic pressure to the trailer brakes.
Periodically check and test the surge “actuator” to make sure
that it is functioning correctly. Never use an undersize actuator.

Trailer Maintenance
Tires/Wheels/Lug Nuts

Suspension

Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing the
trailer wheels it is important the wheels, tires, and axle are
properly matched.

The leaf suspension springs and associated components
(Figure 63) should be visually inspected every 6,000 miles
for signs of excessive wear, elongation of bolt holes, and
loosening of fasteners. Replace all damaged parts
(suspension) immediately. Torqued suspension components
as detailed in Table 15.

CAUTION
ALWAYS wear safety glasses when
removing or installing force fitted parts.
Failure to comply may result in serious
injury.
CAUTION
DO NOT attempt to repair or modify a
wheel. DO NOT install in inner tube to
correct a leak through the rim. If the rim
is cracked, the air pressure in the inner
tube may cause pieces of the rim to explode (break off)
with great force and cause serious eye or bodily injury.

Trailer Maintenance
Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the
fasteners matched to the cone angle of the wheel. Proper
procedure for attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence (see Figure 64). DO
NOT torque the wheel lug nuts all the way down.
Tighten each lug nut in 3 separate passes as defined
by Table 16.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
