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 generator
requires an adequate, free
 ow of cooling air. NEVER
operate this equipment in
any enclosed or narrow area
where free  ow of the air is
restricted. If the air  ow is
restricted it will cause injury to people and property and
serious damage to the equipment or engine.

When operating the generator outdoors, DO NOT place
the generator near doors, windows or vents that could
allow carbon monoxide to enter and build up in occupied
spaces.
WARNING

NEVER place hands or fingers inside the engine
compartment when the engine is running.

NEVER operate the engine with heat shields or
guards removed.

Keep  ngers, hands, hair and clothing away
from all moving parts to prevent injury.

NEVER operate the generator with the
doors open. Stop the engine before servicing.

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 drain the engine oil while the engine is hot. Hot
oil will gush out and severely scald any persons near
the generator.
Operation of the generator may create sparks that
can start  res around dry vegetation. A spark arrestor
may be required. The operator should contact local  re
agencies for laws or regulations relating to  re prevention
requirements.
CAUTION
NEVER touch the hot exhaust manifold,
muf er or cylinder. Allow these parts to cool
before servicing the generator.
NOTICE
NEVER
run the engine without an air  lter or with a dirty
air  lter. Severe engine damage may occur. Service the
air  lter frequently to prevent engine malfunction.
NEVER tamper with the factory settings of
the engine or engine governor. Damage
to the engine or generator 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
suf cient load (less than 30-35% 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 ef 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.

PAGE 14 — TLG8SSK4F2 PORTABLE GENERATOR • OPERATION MANUAL — REV. #0 (04/06/23)
INSTALLATION
OUTDOOR INSTALLATION
Install the generator in an 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 so 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 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.
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.
MOUNTING
The generator must be mounted on a solid foundation
(such as concrete) and set rmly on the foundation to
isolate vibration of the generator when it is running. The
generator must be mounted at least 6 inches above the oor
or grade level as referenced in the National Fire Protection
Association handbook (NFPA 110, Chapter 7, Section 7.4).
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.

ENGINE PROTECTION SYSTEM
Engine protection failsafe features are provided in the event
of low oil pressure, high coolant temperature, or failure of
the battery to charge. If any of the above conditions occur
while the generator is in operation, it will cause a complete
unit shutdown.
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 shut down the engine. If this condition should
occur, please refer to the Engine Troubleshooting table
in this manual.
Water Temperature Alarm
This unit is equipped with a protective device that triggers
an alarm and automatically stops the engine when the
engine coolant temperature becomes abnormally high. This
protective device will not function properly if the machine
is operated with less than the proper amount of coolant.
Battery Charge Alarm
This unit is equipped with a protective device that triggers
an alarm and automatically stops the engine when loss of
charge from the engine alternator occurs.
EXCITATION SYSTEM
The generator uses a brushless exciter to create rated
output electricity. This system will use the mechanical
energy generated by the 3,600 rpm engine to spin the
rotor (or armature) inside the generator (or alternator end).
Excitation current is sourced from the battery to the
excitation winding in the stator. Current applied to this coil
creates a magnetic eld. The rotating armature within the
stator is then induced with AC current.
ENGINE
The generator is powered by a water-cooled, four-cycle,
Kubota diesel engine. This engine is designed to meet
every performance requirement of the generator.
In keeping with Multiquip’s policy of constantly improving
our products, the specications quoted herein are subject
to change without prior notice.
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 the proper extension cable size.

SINGLE-PHASE LOAD
Always be sure to check the nameplate on the generator
and equipment to ensure the wattage, amperage,
frequency, and voltage requirements are satisfactorily
supplied by the generator 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 inuenced by the efciency, power factor
and starting system of the equipment.
WATTS = VOLTAGE × AMPERAGE
The power factor of this generator is 0.8. See Table 5 below
when connecting loads.
NOTICE
If wattage is not given on the equipment’s nameplate,
approximate wattage may be determined by multiplying
the nameplate voltage by the nameplate amperage.
Table 5. Power Factor By Load
Type of Load Power Factor
Single-phase induction motors 0.4–0.75
Electric heaters, incandescent lamps 1.0
Fluorescent lamps, mercury lamps 0.4–0.9
Electronic devices,
communication equipment 1.0
Common power tools 0.8

CAUTION: Equipment damage can result from low voltage.
NOTICE
Cable selection table is a general guideline. ALWAYS
consult local and national electrical codes when sizing
cables.
LOAD APPLICATION
THREE-PHASE LOAD
When calculating the power requirements for 3-phase
power use the following equation:
An inadequately sized 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.
See Table 6.
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.
When connecting a uorescent or mercury lamp, a
capacity of up to the generating set’s rated output (kW)
multiplied by 0.6 can be used.
When connecting an electric drill or other power tools,
pay close attention to the required starting current
capacity.
When connecting ordinary power tools, a capacity of up
to the generating set’s rated output (kW) multiplied by
0.8 can be used.
KVA = VOLTAGE × AMPERAGE × 1.732
1000
NOTICE
If 3-phase load (kVA) is not given on the equipment
nameplate, approximate 3-phase load may be
determined by multiplying voltage by amperage by 1.732.
NOTICE
Motors and motor-driven equipment draw much greater
current for starting than during operation.
DANGER
Before connecting this generator to any building’s
electrical system, a licensed electrician must install
an isolation (transfer) switch. Serious damage to
the building’s electrical system may occur without this
transfer switch.
