plug while the engine is hot will result in hot coolant
to gush out of the coolant drain plug, therefore
causing severe scalding to any persons in the
general area of the generator.
3. Engine Oil Drain Plug - Removing the engine oil
drain plug while the engine is hot will result in hot oil
to gush out of the oil drain plug, therefore causing
severe scalding to any persons in the general area
of the 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.
I
Make sure the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
I
Avoid sudden stops and starts.This can cause skidding,
or jackknifing. Smooth, gradual starts and stops will
improve gas milage.
I
ALWAYS inspect the hitch and coupling for wear.NEVER
tow a trailer with defective hitches, couplings, chains
etc.
I
I

If your trailer has a braking system, the brakes should be
inspected the first 200 miles of operation. This will allow the Before any brake synchronizations adjustments can be made,
brake shoes and drums to seat properly. After the first 200 the trailer brakes should be burnished-in by applying the

brakes to cool between application. This allows the brake
shoes to slightly be seated into the brake drum surface.
Electric Brakes
Electrically actuated brakes (Figure 2) are similar to hydraulic
brakes. The basic difference is that hydraulic brakes are Figure 2 displays the major electric brake components that

will require inspection and maintenance. Please inspect these
components as required.
Listed below are some of the advantages that electric brakes
have over hydraulic brakes:
Electric Brake Adjustment
Brake system can be manually adjusted to provide the 1. Place the trailer on jack stands. Make sure the jack
corrected braking capability for varying road and load
conditions
stands are placed on secure level ground.
2. Check the wheel and drum for free rotation.
Brake system can be modulated to provide more or less
braking force, thus easing the brake load on the towing
vehicle
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.
Brake system has very little lag time between the time
the vehicle’s brakes are actuated and the trailer’s brakes
are actuated
5. Adjust the brake shoes outward until the pressure of the
lining against the wheel drum makes the wheel difficult
to turn.
Brake system can provide an independent emergency
brake system
6. Rotate the star wheel in the opposite direction until the
wheel rotates freely with slight lining drag.
Remember in order to properly synchronize the tow vehicle’s
braking to the trailer’s braking, can only be accomplished by
road testing. Brake lockup, grabbiness or harshness is due
to lack of synchronization between the tow vehicle and the
7. Replace the adjusting hole cover and lower the trailer to
the ground.

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 4) 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:
NOTE
ALWAYS wear safety glasses when removing
or installing force fitted parts. Failure to comply
may result in serious injury.

DCA-400SPK — GENERAL INFORMATION
Engine
The DCA-400SPK is powered by a 4 cycle, water cooled,
turbocharged KOMATSU Model SA6D140-Adiesel engine.
This engine is designed to meet every performance
requirement for the generator. Reference Table 1, page 16
for engine specifications.
In keeping with Multiquip's policy of constantly improving
its products, the specifications quoted herein are subject to
change without prior notice.
The basic controls and indicators for the DCA-400SPK
generator are addressed on the following pages.
Mechanical Governor System
The mechanical governor system control the RPM of the
engine. When the engine demands increase or decrease,
the mechanical governor system regulates the frequency
variation to 1.5%. The electronic governor option in-
creases frequency variation to 0.25%.
JacketWater Heater (OPTIONAL)
The jacket water heater is a 1500-watt heater designed to
keep the coolant warm in the engine block for fast starts
and load acceptance. The heater is thermostatically
controlled and once an acceptable engine temperature is
achieved it will cycle on and off, operating only about 1/3 of
the time, which makes it more efficient than the direct block
type heater. It is designed to keep the engine coolant
between 100 and 120 degrees Fahrenheit.
Under normal conditions, 20 to 15 minutes is required to
raise the engine temperature of a cold engine to 100 degrees
Fahrenheit.
Battery Charger
The battery charger will operate in a‘BOOST’mode until the
battery’s current acceptance falls to 70% of the charger’s
rating. The charger will then go into a ‘FLOAT’mode, where
it discharges a lower voltage until an AC failure, or the battery
is discharged.

DCA-400SPK — INSTALLATION
CAUTION
:
Outdoor Installation
An electric shock may happen when
vibrators are used. Pay close attention to
handling when operating vibrators and
always use rubber boots and gloves to
insulate the body from electrical shock.
Install the generator in a location where it will not be exposed
to rain or sunshine. 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.
Generator Grounding
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.
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.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and 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 27) 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 heat
excessively and possibly burn the valves.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried a minimum of 8 ft. into the ground.
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.

General Inspection Prior to Operation
Circuit Breakers
The DCA-400SPK generator has been thoroughly inspected
and accepted prior to shipment from the factory. However,
be sure to check for damaged parts or components, or loose
nuts and bolts, which could have occurred in transit.
To protect the generator from an overload, a 3-pole,1060
amp, main circuit breaker is provided to protect the UVW
output terminals from overload. In addition two single-pole,
20 amp GFCI circuit breakers are provided to protect the
GFCI receptacles from overload.Three 50 amp load circuit
breakers have also been provided to protect the load side of
the generator from overload. Make sure to switch ALL circuit
breakers to the "OFF" position prior to starting the engine.
Extension Cable
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 Guide (Table 10)
as a guide for selecting proper cable size.
NOTE
ALWAYS consult with a licensed
electrician for correct extension
cord wire size.

Figure 30. Battery Connections
Battery
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.
CAUTION
:
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.
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 the battery is
discharged and needs to be recharged or replaced.
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 inhibit corrosion.
When connecting battery do the following:
1. DO NOT connect the battery cables to the battery
terminals when the Off/Manual/Auto switch is in either
the manual or auto position (ON). ALWAYS make sure
that the Off/Manual/Auto switch is in the OFF position
when connecting the battery.
2. Place a small amount of grease around both battery
terminals. This will ensure a good connection and will

This generator is equipped with two 120VAC, 20 amp output
receptacles located on the output terminal panel, page 43,
Figure 14.
z
The engine's exhaust contains harmful
emissions. ALWAYS ventilate the
exhaust when operating inside tunnels,
excavations or buildings. Direct exhaust
away from nearby personnel.
The purpose of these receptacles is to provide power via
commercial power to the jacket water heater and internal
battery charger.
Before Starting
Engine
These receptacles will ONLY function when commercial
power has been supplied to them (Figure 31). To apply
commercial power to these receptacles, a power cord of
adequate size will be required.
1. Check the lubricating oil level prior to starting the engine.
Make sure the generator is level. The oil level must be
maintained between two notches on the dipstick.
2. When there is not enough lubricating oil, fill the crankcase
with high grade motor oil. Use a high quality detergent
oil classified CC or higher (See Table 11 on page 43).
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.
3. Check the coolant level in the radiator and subtank.
Replenish with antifreeze as necessary.Always maintain
the coolant level between the FULL and LOW markings
on the coolant container. Be sure the radiator cap is
fastened securely.
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 an power cord of
adequate size.
4. Check the fuel level on the fuel gauge. If fuel is low, fill
the fuel tank with clean fresh unleaded automotive diesel.
If diesel spillage occurs, completely wipe up the spilled
fuel immediately.
