■
■
ALWAYS attach trailer's safety chain to bumper of towing  
vehicle.  
CAUTION :  
ALWAYS make sure the vehicle and trailer directional,  
backup, brake, and trailer lights are connected and are  
working properly.  
Check with your county or state safety  
towing regulations department before  
towing your generator. Vehicle towing  
codes and regulations can vary from state  
to state.  
■
The maximum speed (unless otherwise posted) for highway  
towing is 45 MPH. Recommended off-road towing is not to  
exceed 10 MPH or less, depending on type of terrain.  
To reduce the possibility of an accident while transporting  
the generator on public roads, always make sure the trailer  
and the towing vehicle 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.  
Remove wheel stand when transporting.  
DO NOT transport generator with fuel in tank.

DCA-10SPX3 —TRAILER SAFETY GUIDELINES  
Tires/Wheels/Lug Nuts  
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.  
Suspension  
The leaf suspension springs and associated components  
(Figure 2) 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 3.  
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.  
Table 2 (Tire Wear Troubleshooting) will help pinpoint the  
causes and solutions of tire wear problems.  
CAUTION:  
Figure 2. Major Suspension Components  
NOTE  
ALWAYS wear safety glasses when removing  
or installing force fitted parts. Failure to  
comply may result in serious injury.

DCA-10SPX3 — GENERAL INFORMATION  
DCA-10SPX3 3 FAMILIARIZATION  
Generator  
Open Delta Excitation System  
The DCA-10SPX3 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-10SPX3 is a 10 kW generator  
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 Leads: A, B, C and D. During light loads, the  
power to the AutomaticVoltage Regulator (AVR) is supplied  
from the leads of B & C, when loads increase, the AVR  
switches and accepts power from leads A & D. The output  
of leads A & D increase proportionally with load. This has  
the effect of adding the voltages of each phase to provide  
better voltage response during heavy loads.  
Control Panel  
The control panel is provided with the following:  
One GFCI 120 volt receptacle, 20 amp (single-phase)  
10 kW Output Terminal (UNV)  
Main Circuit Breaker 45 amps  
GFCI Circuit Breaker 20 amps  
AC Ammeter  
AC Voltmeter  
Output Voltage Adjustment  
Ignition Switch  
WaterTemperature Gauge  
Oil Pressure Gauge  
Warning Indicator  
Frequency Meter (Hz)  
Hour Meter  
GroundTerminal  
The connections of the AVR to the AC output windings are  
for the sole purpose of sensing only. No power is required  
from these windings.  
The open-delta design provides virtually unlimited excitation  
current due to its independent power supply 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-10SPX3 is powered by a 3-cylinder KUBOTA Model  
D1403 diesel engine.This engine is designed to meet every  
performance requirement for the generator.ReferenceTable  
5, page 19 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.

DCA-10SPX3 — INSTALLATION  
Outdoor Installation  
CAUTION :  
Install the generator in a location where it is not exposed to  
rain or sunshine. Make sure the generator is on a secure  
level ground so that it cannot slide or shift around. Also  
install the generator in a manner so the exhaust will not be  
discharged in the direction of nearby homes.  
An electric shock is apt to happen when  
vibrators are used. Pay close attention  
to handling when operating vibrators and  
always use rubber boots and gloves to  
protect the body from electrical shock.  
The installation site must be away from excessive 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.  
Generator Grounding  
To prevent 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.  
Foreign materials such as dust, sand, lint and abrasive  
materials cause excessive wear, to the engine parts and  
the alternator parts.  
NEC articles 250-64(b) and 250-66 set the following  
grounding requirements:  
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.  
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 12) 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 overheat.  
3. NEC article 250-52(c) specifies that the earth ground  
rod should be buried a minimum of 8 ft. into the ground.  
NOTE  
When connecting the generator to  
any buildings electrical system  
ALWAYS consult with a licensed  
electrician.  
Eliminate the danger of deadly carbon monoxide gas.  
Remember that exhaust fumes from any diesel engine are  
very poisonous if discharged in a closed room, but harmless  
if allowed to mix with the outside air. If the generator is  
installed indoors, you must make provisions from venting  
the engine exhaust to the outside of the building.  
DO NOT cover ventilation areas on the enclosure. Covering  
the ventilation grids will cause the engine to overheat.

and accepted prior to shipment from the factory. However, main circuit breaker is provided to protect the UNV output  
be sure to check for damaged parts or components, or loose from overload. In addition a 2-pole, 20 amp GFCI circuit  
nuts and bolts, which could have occurred in transit.  
breaker is provided to protect the GFCI receptacle from  
overload. Make sure to switch both circuit breakers to the  
"OFF" position prior to starting the engine.  
Extension Cable  
When electric power is to provided to loads (ie. power  
tools) at a distance from the generator, extension cables  
are 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 Table 6 (cable selection guide) as a guide for selecting  
proper cable size.  
NOTE  
ALWAYS consult with a licensed  
electrician for correct extension  
cord wire size.

Fuel  
Lubrication Oil  
Fill the fuel tank with clean and fresh diesel fuel. DO NOT  
fill the tank beyond capacity.  
Fill the engine crankcase with lubricating oil through the filler  
hole, but do not overfill. Make sure the generator is level.  
With the dipstick inserted all the way, but without being screw  
into the filler hole, verify that the oil level is maintained  
between the two notches (Figure 13) on the dipstick. See  
Table 7 for proper selection of engine oil.  
Pay attention to the fuel tank capacity when replenishing  
fuel. Refer to the fuel tank capacity listed on page 19  
Specification Table 5.  
The fuel tank cap must be closed tightly after filling. Handle  
fuel in a safety container. If the container does not have a  
spout, use a funnel. Wipe up any spilled fuel immediately.  
CAUTION :  
Never fill the fuel tank while the engine is  
running or in the dark. Gasoline spillage  
on a hot engine can cause a fire or  
explosion. If gasoline spillage occurs, wipe  
up the spilled gasoline completely to  
prevent fire hazards.  
Coolant  
Use only drinkable tap water. If hard water or water with  
many impurities is used, the inside of the engine and radiator  
may become coated with deposits and cooling efficiency  
will be reduced. See maintenance section on page 36 and  
37 on instructions to flush out radiator.  
Figure 13. Engine Oil Dipstick  
When checking the engine oil, be sure to check if the oil is  
clean and viscous. If the oil is dirty, drain the oil by removing  
the oil drain plug, and refill with the specified amount of oil  
as outlined in the Kubota Engine Owner's Manual.  
An anticorrosion additive added to the water will help prevent  
deposits and corrosion in the cooling system.

CAUTION :  
Cleaning the Outer 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 radiator is  
dangerous, so clean only with the engine turned off and the  
battery disconnected.  
When adding coolant or antifreeze to the  
radiator, do not remove the radiator cap  
until the unit has completely cooled.  
Day-to-day addition of coolant is done from the reserve tank.  
When adding coolant to the radiator, DO NOT remove the  
radiator cap until the unit has completely cooled. See Table  
8. for engine, radiator, and reserve tank coolant capacities.  
Make sure the coolant level in the reserve tank is always  
between the "H" and the "L" markings.  
Air Cleaner  
Periodic cleaning/replacement is necessary. Inspect it in  
accordance with the Kubota Engine Owner's Manual.  
Fan BeltTension  
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 Kubota  
Engine Owner's Manual.

DCA-10SPX3 — PRE-SETUP  
Battery  
CAUTION :  
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 is not  
properly maintained. Add only distilled water when  
replenishment is necessary. DO NOT over fill.  
If the battery cable is connected  
incorrectly, damage to the generator will  
occur. Pay close attention to the polarity  
of the battery when connecting the  
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, it indicates that the battery is  
dead and needs to be recharged or replaced.  
When connecting battery do the following:  
1. DO NOT connect the battery cables to the battery  
terminals when the key is in the ignition and is set in  
'START' mode. ALWAYS remove the key from the  
ignition and the ignition switch is in the OFF position  
when connecting the battery.  
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 a thin film of grease will help to inhibit corrosion.  
2. Place a small amount of grease around both battery  
terminals. This will ensure a good connection and will  
help prevent corrosion around the battery terminals.  
Battery Cable Installation  
ALWAYS be sure the battery cables (Figure 15) 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 :  
Inadequate battery connections may  
cause poor starting of the generator, and  
create other malfunctions.  
Wiring  
Inspect the entire generator for bad or worn electrical wiring  
or connections. If any wiring or connections are exposed  
(insulation missing) replace wiring immediately.  
Piping and Hose Connection  
Inspect all piping, oil hose, and fuel hose connections for  
wear and tightness.Tighten all hose clamps and check hoses  
for leaks.  
If any hose (fuel or oil) lines are defective replace them  
immediately.

DCA-10SPX3 — LOAD APPLICATION  
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.  
Single Phase, Load  
Always be sure to check the nameplate on the generator  
and equipment to insure the wattage, amperage and  
frequency requirements are satisfactorily supplied by the  
generator for operating the equipment.  
●
●
●
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.  
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.  
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.  
NOTE  
When connecting an electric drill or other power tools,  
pay close attention to the required starting current  
capacity.  
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 10.  
below when connecting loads.

CAUTION:  
Motors and motor-driven equipment draw  
much greater current for starting than during  
operation.  
When connecting ordinary power tools, a capacity of up to  
the generating set’s rated output (kW) multiplied by 0.8 can  
be used.

DCA-10SPX3 — MAINTENANCE  
General Inspection  
Check Oil Level  
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.  
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 8, page 29.  
Engine Side (Refer to the Engine Instruction Manual)  
Replacing Oil Filter  
Air Cleaner  
Detach the oil filter cartridge with a filter wrench.  
Apply a film of oil to the gasket for the cartridge.  
Every 50 hours: Remove air cleaner element and clean heavy  
duty paper element with kerosene, or foam element with  
liquid detergent and hot water. Wrap foam element in a cloth  
and squeeze dry. For heavy duty paper element, wipe  
excess kerosene with towel.  
Screw in the cartridge by hand. When the gasket is in  
contact with the seal surface, tighten the cartridge one  
or two more times by hand.  
Fuel Addition  
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.  
Add diesel fuel (the grade may vary according to season  
and locations). Always pour through the mesh filter.  
Removing Water from the Fuel Tank  
Replacing Fuel Filter  
After prolonged use, water and other impurities accumulate  
in the bottom of the tank. Occasionally remove the drain  
cock and drain the contents. 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 as  
much as possible.  
Replace the fuel filter cartridge with new one every 400  
hours or so.  
Apply fuel oil thinly over the gasket and hand-tighten  
the cartridge into position.  
Vent any air.  
Flushing Out Radiator and Replacing Coolant  
Air Removal  
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.  
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.  
Check hoses for softening and kinks. Check clamps  
for signs of leakage.  
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.  
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.  
Service Daily  
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 in high fuel consumption.  
Tighten both cocks and replace the overflow tank.  
Replace with coolant (see page 30,Table 5 for mixture).  
Close radiator cap tightly.  
CAUTION :  
Cleaning the Fuel Strainer  
Allow engine to cool when flushing out  
radiator. Flushing the radiator while hot  
will damage radiator.  
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.
