CAUTION - ENGINE LOAD (WET-STACKING)
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 turbocharges, 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 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.

DCA10SPX4/DCA10SPXU4 — 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 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 - EXHAUST HAZARD
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
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 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 - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
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 aminimum 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.
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.
NOTE
When connecting the generator
to any buildings electrical
system ALWAYS consult with
a licensed electrician.

Open Delta Excitation System
The generator is equipped with the state of the art "
Delta
" excitation system. The open delta system consist of
Open-
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
The DCA-10SPX4 is powered by a 3 cylinder, water cooled,
Kubota Model D1503-M 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.

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 11 as a general engine
maintenance guideline (Refer to the Engine Instruction
Manual).
Air Cleaner
Every 250 hours: Remove air cleaner element and clean
the heavy duty paper element with light spray of compressed
air. Replace the air cleaner as needed.
Air Cleaner with Dust Indicator (If Equipped)
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
Service Daily
If the engine is operating in very
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
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.

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
Engine Manual
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 12.
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.
Check hoses for softening and kinks. Check clamps for
signs of leakage.
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.
Tighten both cocks and replace the overflow tank.
Replace with coolant as recommended by the engine
manufaturer.
Close radiator cap tightly.

Cleaning the Fuel Strainer
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
Securely fasten the fuel strainer cap so that fuel will not leak.
Check the fuel strainer every 200 hours of operation or once
a month.
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.
For longe term storage of the generator the following is
recommended:
Fill the fuel tank completely. Treat with a fuel stabilizer if
necessary.
Completely drain the oil from the crankcase and refill if
necessary with fresh oil.
Clean the entire generator, internal and external.
Cover the generating set and store in a clean, dry place.
Disconnect the battery.
Make sure engine coolant is at proper level.

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 33). 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.
