PAGE 8 — DAC7000 SERIES GENERATORS• OPERATION AND PARTS MANUAL — REV. #0 (02/15/16)
SAFETY INFORMATION
ENGINE SAFETY
DANGER

The engine fuel exhaust gases contain poisonous carbon
monoxide. This gas is colorless and odorless, and can
cause death if inhaled.

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.
WARNING

DO NOT place hands or fingers inside engine
compartment when engine is running.

NEVER operate the engine with heat shields or
guards removed.

Keep fingers, hands hair and clothing away
from all moving parts to prevent injury.

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.

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.
NOTICE
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.
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.

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.
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 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.

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.

INSTALLATION
OUTDOOR INSTALLATION
If possible 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.
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.
INDOOR INSTALLATION
Exhaust gases from gas 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.
PLACEMENT
The generator should always be placed on a flat level
surface when it is running. DO NOT place the generator on
slopes, the possibility exists that the generator could slide.
WARNING
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
DANGER
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
insulate the body from a short circuit.
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 a minimum of 8 ft. into the ground.
NOTICE
When connecting the generator to any buildings
electrical system ALWAYS consult with a licensed
electrician.
DANGER
Before connecting this generator to any building’s
electrical system, a licensed electrician must install an
isolation (transfer) switch.
Serious injury or death may result without this transfer
switch.

Engine Protection System
Engine protection fail safe features are provided in the event
of low oil pressure, high coolant temperature and failure of
the battery to charge. If any of the above conditions occur
while operating the generator it will cause a complete unit
shut down.
Battery Charge Alarm
This unit is equipped with a protective device that signals
an alarm and automatically stops the engine when the
battery cannot be charged by the alternator
Water Temperature Alarm
This unit is equipped with an apparatus that signals
an alarm and automatically stops the engine when the
cooling water temperature becomes abnormally high.
This apparatus will not function properly if the machine
is operated with less than the proper amount of coolant.
Oil Pressure Warning Alarm
This unit is equipped with a protective device that detects
low oil pressure. If the lubricating oil pressure of this unit
should become abnormally low, the protective device will
automatically stop the engine. If this condition should
occur, please refer to the engine troubleshooting table in
this manual.
Idle Control Switch
The DAC7000 series generators are provided with
an automatic idle (engine) control capability for noise
suppression and fuel cost reduction. The automatic idle
control feature automatically engages under a no-load
condition.
With AC loads of more than 150W (such as lighting
equipment, motor-powered tools, submersible water
pumps, etc.), the engine runs at high speed.When a no load
condition is produced, the engine automatically slows down.
Turn the idle control switch to the “ON” (up) position when
AC loads of more than 150W are connected. Turn the idle
control switch to the “OFF” (down) position when AC loads
of less than 100W or when a magnetic switch is used.
Excitation System
The DAC7000 series generators use a brushless exciter
to create rated output electricity. This system will use the
mechanical energy generated by the 3600 RPM engine
to spin the rotor (or armature) inside the generator (or
alternator end).
Excitation current is sourced from the battery to the
excitation windinding in the stator. Current applied to this
coil creates a magnetic field. The rotating armature is
induced with AC current.
Engine
The DAC7000 series generators are powered by a water-
cooled, 4-cycle KUBOTA diesel engine. This engine is
designed to meet every performance requirement of the
generator. Reference Table 2, engine specifications.
In keeping with Multiquip's policy of constantly improving
its products, the specifications quoted herein are subject
to change without prior notice.
Figure 3 and Figure 4 show the basic controls and indicators
for the DAC7000 series generators.
