DA7000 SERIES GENERATORS • OPERATION AND PARTS MANUAL — REV. #5 (01/20/11) — PAGE 7
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
fl ow of cooling air. NEVER
operate this equipment in
any enclosed or narrow area
where free fl ow of the air is
restricted. If the air fl ow 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 fi ngers, 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,
muffl er or cylinder. Allow these parts to cool
before servicing equipment.
NOTICE
NEVER run engine without an air fi lter or with a dirty air
fi lter. Severe engine damage may occur. Service air fi lter
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
suffi cient 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 effi ciency,
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 fl ames
from the engine exhaust. Spark arresters are qualifi ed
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.
PAGE 8 — DA7000 SERIES GENERATORS• OPERATION AND PARTS MANUAL — REV. #5 (01/20/11)
SAFETY INFORMATION
FUEL SAFETY
DANGER
DO NOT start the engine near spilled fuel or combustible
fl uids. Diesel fuel is extremely fl ammable and its vapors
can cause an explosion if ignited.
ALWAYS refuel in a well-ventilated area, away from
sparks and open fl ames.
ALWAYS use extreme caution when working with
fl ammable liquids.
DO NOT fi ll the fuel tank while the engine is running
or hot.
DO NOT overfi ll tank, since spilled fuel could ignite if it
comes into contact with hot engine parts or sparks from
the ignition system.
Store fuel in appropriate containers, in well-ventilated
areas and away from sparks and fl ames.
NEVER use fuel as a cleaning agent.
DO NOT smoke around or near the
equipment. Fire or explosion could result
from fuel vapors or if fuel is spilled on a
hot engine.
TOWING SAFETY
CAUTION
Check with your local county or state safety
towing regulations, in addition to meeting
Department of Transportation (DOT)
Safety Towing Regulations, before towing
your generator.
Refer to MQ Power trailer manual for additional safety

• Secure portable power cables in cable tray with tie
wraps.
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.
Avoid sudden stops and starts. This can cause skidding,
or jack-knifi ng. Smooth, gradual starts and stops will
improve towing.
Avoid sharp turns to prevent rolling.
Trailer should be adjusted to a level position at all times
when towing.
Raise and lock trailer wheel stand in up position when
towing.
Place chock blocks underneath wheel to prevent rolling
while parked.
Place support blocks underneath the trailer’s bumper
to prevent tipping while parked.

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.
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
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
specifi es 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 - 8 AWG (5.3 mm2)
b. Aluminum - 6 AWG (8.4 mm2)
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.
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 fl at level
surface when it is running. DO NOT place the generator on
slopes, the possibility exists that the generator could slide.
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.
3. NEC article 250-52(c) specifi es 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.

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.
Excitation System
The DA7000 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 fi eld. The rotating armature is
induced with AC current.
Engine
The DA7000 series generators are powered by a watercooled, 4-cycle KUBOTA diesel engine. This engine is
designed to meet every performance requirement of the
generator. Reference Table 2, engine specifi cations.
In keeping with Multiquip's policy of constantly improving

LOAD APPLICATIONS
Single Phase Load — 60 Hz
Always be sure to check the nameplate on the generators
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generators 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 infl uenced by the effi ciency, power factor
and starting system of the equipment.
NOTICE
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 generators is 1.0 See Table 3 below
when connecting loads.
Table 3. Power Factor By Load
To determine the running wattage for your load, multiply the
running wattage as indicated by steps 1, 2, and 3 below:
1. INCANDESCENT LOADS
Lights, heaters and similar appliances.
total the running wattage and multiply by 1.
Example:
29 light bulbs @ 100W each = 2.9 kW
use a 3 kW generator.
2. SMALL MOTORS
Drills and other small power tools.
Total the running wattage and multiply by 2.
Example:
A 1 inch drill runs at 1 kW
use a 2 kW generator
3. LARGE MOTORS
Submersible pumps, table saws etc.
Total the running wattage and multiply by 3.
Example:
A conveyor belt runs at 8 kW
use a 24 kW generator.

NOTICE
Motors and motor-driven equipment draw much greater
current for starting than during operation. Always use
an adequate size extension cable which can carry the
required load.
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 generators and point of use (load) is held
to a minimum. Use the cable selection chart (Table 4) as a
guide for selecting proper cable size.
NOTICE
The idle control device is operated at a minimum load
capacity of 100W. If the load capacity is less than 100W,
