weight rating.”
■
■
ALWAYS know the location of the nearest and first aid kit.
ALWAYS inspect the hitch and coupling for wear. NEVER
tow a trailer with defective hitches, couplings, chains
etc.
Check the tire air pressure on both towing vehicle and
trailer. Trailer tires should be inflated to 50 psi cold.
Also check the tire tread wear on both vehicles.
In emergencies always know the location of the
nearest phone or keep a phone on the job site.
Also know the phone numbers of the nearest
ambulance, doctor and fire department. This
information will be invaluable in the case of an
emergency.
■
■
■
ALWAYS make sure the trailer is equipped with a "Safety
Chain".
ALWAYS attach trailer’s safety chains to towing vehicle
properly.
ALWAYS make sure the vehicle and trailer directional,
backup, brake, and trailer lights are connected and
working properly.
■
The maximum speed for highway towing is 55 MPH
unless posted otherwise. Recommended off-road towing
is not to exceed 15 MPH or less depending on type of
terrain.
■
■
■
Place chock blocks underneath wheel to prevent rolling,
while parked.
Use the trailer’s swivel jack to adjust the trailer height to
a level position while parked.

are in good operating condition and both units are
mechanically sound.
■
■
■
Place chocked blocks underneath wheel to prevent
rolling, while parked.
Place support blocks underneath the trailer’s bumper to
prevent tipping, while parked.
The following list of suggestions should be used when towing
your generator:
Use the trailer’s hand winch to adjust the height of the
trailer, then insert locking pin to lock wheel stand in place,
while parked.
■
Make sure the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
■
Avoid sudden stops and starts. This can cause skidding,
or jackknifing. Smooth, gradual starts and stops will
improve gas milage.
■
ALWAYS inspect the hitch and coupling for wear.NEVER
tow a trailer with defective hitches, couplings, chains
etc.
■
■
■
Avoid sharp turns to prevent rolling.
■
■
Check the tire air pressure on both towing vehicle and

DCA-125USJ (50 HZ)— GENERAL INFORMATION
DCA-125USJ (50 HZ) Series Familiarization
Open Delta Excitation System
Generator
The DCA-125USJ (50 HZ)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.
The MQ Power Model DCA-125USJ (50 HZ)is a 80 kW
generator (Figure 5) that 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.
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.
Engine Operating Panel

Auto ON/OFF Engine Controller (MPEC)
Fuel Leak Detected Alarm Lamp
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.
Generator Control Panel
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.

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.

hole, but DO NOT overfill. Make sure the generator is level.
and verify that the oil level is maintained between the two
notches (Figure 31) on the dipstick. See Table 8 for proper
selection of engine oil.
Refilling the Fuel System
WARNING:
ONLY properly trained personel who have
read and understand this section should re-
fill the fuel tank system.
Figure 31. Engine Oil Dipstick
The generator unit has an internal fuel tank located at the
bottom of the cabinet (Figure 32). ALWAYS fill the fuel tank
with clean and fresh #2 diesel fuel. DO NOT fill the fuel
tanks beyond their capacities.
When checking the engine oil, be sure to check if the oil is
clean. If the oil is not clean, drain the oil by removing the oil
drain plug, and refill with the specified amount of oil as outlined
in the John Deere Engine Owner's Manual. Oil should be
warm before draining.
Pay attention to the fuel tank capacity when replenishing
fuel.The fuel tank cap must be closed tightly after filling.

brakes more frequently.
Figure 56 displays the major hydraulic surge brake
components that will require inspection and maintenance.
Please inspect these components as required using steps 1
through 8 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.
4. With a screwdriver or standard adjusting tool, rotate the
star wheel of the adjuster assembly to expand the brake
shoes.
Figure 56. 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.
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.

loosening of fasteners. Replace all damaged parts
(suspension) immediately. Torqued suspension components
as detailed in Table 14.
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.
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.
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.
Figure 57. Major Suspension Components
Table 10 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.

Lug NutTorque 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 58). DO NOT
torque the wheel lug nuts all the way down.Tighten each
lug nut in 3 separate passes as defined by Table 15.
3. After first road use, retorque all lug nuts in sequence.
Check all wheel lug nuts periodically.
