engine saFeTY
NOTICE
danger
„ 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.
„ The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.
„ 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.
„ 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.
„ 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.
Warning
„ do noT place hands or fingers inside engine
compartment when engine is running.
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.
„ never operate the engine with heat shields or
guards removed.
„ Keep fingers, hands hair and clothing away
from all moving parts to prevent injury.
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.
„ 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.
„ 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.
„ 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.

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).
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.
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.
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.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
a. Copper - 8 AWG (5.3 mm2)
b. Aluminum - 6 AWG (8.4 mm2)
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.
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.
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.
NOTICE
When connecting the generator to any buildings
electrical system alWaYs consult with a licensed
electrician.
NOTICE
This generator has a permanent bonding conductor
between the generator stator windings and the frame.
mounTing
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.

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 “open-
delta” 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.
operaTing panel
The “Operating Panel” is provided with the following:
„ ECU Controller
„ Gauge Unit Assembly
• Oil Pressure Gauge
• Water Temperature Gauge
• Charging Voltmeter
• Fuel Gauge
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.
• Tachometer
„ Panel Light/Panel Light Switch
„ Hour Check Button
„ Auto Start/Stop Switch
„ Engine Speed Switch
„ Emergency Stop Button
„ Water Temperature Gauge
conTrol panel
The “Control Panel” is provided with the following:
„ Frequency Meter (Hz)
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.

„ AC Voltmeter (Volts)
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.

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.

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.
NOTICE
Motors and motor-driven equipment draw much greater
current for starting than during operation.
WATTS = VOLTAGE x AMPERAGE
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.
The power factor of this generator is 0.8.SeeTable 5 below
when connecting loads.
„ 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.

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.
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.
air cleaner
Warning
Periodic cleaning/replacement is necessary. Inspect air
cleaner in accordance with the cummins engine owner’s
manual.
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.
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.
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.
The fan belt tension is proper if the fan belt bends 10 to 15
mm (Figure 33) when depressed with the thumb as shown
below.

„ Forced (stationary) regeneration — A forced
regeneration only occurs when the operator has initiated
this action at the ECU and the ECM recognizes a pre-
programmed set point of soot in the PDF to allow a forced
regeneration cycle.
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.
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.
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.
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.
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.
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.

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.
Pre-Alarm
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.
Alarm Screen
Acknowledge Change

Option
„ passive regeneration — Occurs during normal
operation, typically under heavy load applications. Soot
is oxidized faster than it is collected.
Figure 59. ECU DPF Pre-Alarm
The DPF pre-alarm status symbol displayed in Figure 59
indicates the soot level buildup has exceeded a pre-
determined level and a "Forced Regeneration" action is
required.
„ 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.
NOTICE
If the amBer pre-alarm warning LED is ever on,
the operator should always take immediate action to
correct the problem. If the engine is allow to run under
this condition, a higher pressure differential will be
created in the DPF and will result in the red status
LED being on, causing an engine shutdown.
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.

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.
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.
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:
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.
Figure 62. Hydraulic Brake Components
4. With a screwdriver or standard adjusting tool, rotate
the star wheel of the adjuster assembly to expand the
brake shoes.
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.
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.
Periodically check and test the surge “actuator” to make sure
that it is functioning correctly.Never use an undersize actuator.
8. Repeat steps 1 through 7 on the remaining brakes.

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.
Figure 63. Major Suspension Components
Tire Wear/inflation
Tire inflation pressure is the most important factor in tire
life. Pressure should be checked cold before operation do
noT bleed air from tires when they are hot!.Check inflation
pressure weekly during use to insure the maximum tire life
and tread wear.

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.
