NFPA are appropriate.
e. Store fuel only in an approved container, and
only in a well ventilated area.
f. Follow local codes for closeness to
combustible material.
3. DEADLY EXHAUST GAS Exhaust fumes from
any gasoline engine contain carbon monoxide, an invisible, odorless and deadly gas that must be mixed
with fresh air.
a. Operate only in well ventilated areas.
b. Never operate indoors including attached
garages
c. Never operate the unit in such a way as to
allow exhaust gases to seep back into closed
rooms (i.e. through windows, walls, fl oors).
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
***********************************************************
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or
moderate injury. It may also be used to alert against

TESTING POLICY
UNIT CAPABILITIES
Before any generator is shipped from the factory, it
is fully checked for performance. The generator is
loaded to its full capacity, and the voltage, current
and frequency are carefully checked.
Rated output of generator is based on engineering
tests of typical units, and is subject to and limited
by, the temperature, altitude, fuel, and other conditions specifi ed by the manufacturer of the applicable
engines.
INTENDED USES
This engine generator set has been designed primarily for portable heavy duty commercial use. Both
120 volt and 240 volt receptacles are provided in the
control panel to plug in your loads (lights, portable
tools, and small appliances).
This portable unit requires large quantities of fresh
air for cooling the engine and generator. For safety,
long life and adequate performance, these units
should never be run in small compartments without
positive fresh air fl ow.
GENERATOR CONNECTIONS
DL6000H/DL6000HE - 120 volt and 240 volt receptacles are provided for connection to various
loads. The diagram below represents this 5500 watt
(rated output) generator. A & B represent the 120
volt output legs of this generator. Up to 2250 watts
at 120 volts (22.9 Amps) can be drawn from each
of the receptacles attached to either of the A or B
output legs. This generator is capable of producing
22.9 Amps of 240 volt current at C. Check the appliance or tool nameplates for the current and voltage
to insure compatibility. Remember that power taken
from C reduces the power available at both A and B
and vice versa.
RESTRICTED USES
DO NOT remove from the cradle assembly. Re-
moval of the generator from the cradle assembly
may cause excessive vibration and damage to the
engine-generator set.
DO NOT install and operate this generator in a small
compartment., i.e. generator compartments of vehicles, motor homes or travel trailers. These compartments will not allow enough free fl ow of fresh
air to reach the engine generator set for cooling and
will cause the unit to overheat, damaging both the
engine and generator. Small compartments will also
develop hot spots where there is very little air fl ow
and may cause a fi re.
PLEASE NOTE There are 3rd party companies
making enclosures for generators that have been
properly engineered. The use of these 3rd party
enclosures is acceptable as long as they have been
certifi ed and meet current code.
DO NOT attempt to operate at 50 cycles. These
units are designed and governed to operate at 60
cycles only.

Reference C = 120/240 Volt Twistlock Receptacle

DL5000H - the same principles apply to this unit as
the one described above, only you are limited to
4500 watts or 18.75 amps at each 120 volt receptacle and 18.75 amps at 240 volt.
STARTING ELECTRIC MOTORS
Electric motors require much more current (amps) to
start them than to run them. Some motors, particularly low cost split-phase motors, are very hard
to start and require 5 to 7 times as much starting
current as running current. Capacitor motors are
easier to start and usually require 2 to 4 times as
much starting current as running current. Repulsion
Induction motors are the easiest to start and require
only 1 1/2 to 2 1/2 times as much starting as running
current.
3072-10

60707-125
Most fractional horsepower motors take about the
same amount of current to run them whether they
are Repulsion Induction (RI), Capacitor (Cap), or
Split-Phase (SP) type.
If the electric motor is connected to a hard starting
load, such as an air compressor, it will require more
starting current. If it is connected to a light load,
or no load such as a power saw, it will require less
starting current. The exact requirement will also
vary with the brand or design of the motor.
Self-exciting generators respond to severe overloading differently than utility power. When overloaded,
the engine is not able to supply enough power to
bring the electric motor up to operating speed. The
generator responds with high initial starting current,
but the engine speed drops sharply. The overload
may stall the engine. If allowed to operate at very
low speeds, the electric motor starting winding will
burn out in a short time. The generator winding
might also be damaged.
CAUTION: EQUIPMENT DAMAGE
RUNNING THE GENERATOR SET UNDER
THESE CONDITIONS MAY RESULT IN DAMAGE
TO THE GENERATOR STATOR AS WELL AS THE
MOTOR WINDING.
1. This generator-set was in good order when
shipped. Inspect the generator-set promptly after
receiving it. If any damage is noted, notify the transportation company immediately; request proper procedures for fi ling a “concealed damage” claim. Title
to the equipment and responsibility for fi ling a claim
rests with you when a generator set is sent F.O.B.
shipping point. Only you can legally fi le a claim.
2. Before proceeding with the preparations of your
new generator set for operation, take a couple of
minutes to ensure the unit you have received is the
correct model and review the specifi cation pages in
this manual to insure that this unit meets your job
requirements.
LUBRICATION
Before starting the engine, fi ll the crankcase to the
proper level with a good quality oil. The recommended grade of oil and quantity of oil required is
listed in the engine operator’s manual and below in
this manual. This unit was shipped with most of the
oil removed. The engine normally holds 19 to 20
ounces of oil. Since there is some trapped oil in the
engine, when fi lling the crankcase the fi rst time use
the dipstick to ensure that you do not over fi ll the
crankcase. The blow-up shows the full oil level mark
on the dipstick.
The heavy surge of current required for starting
motors is required for only an instant. The generator will not be damaged if it can bring the motor up
to speed in a few seconds of time. If diffi culty is
experienced in starting motors, turn all other electrical loads off and if possible reduce the load on the
electric motor.
PREPARING THE UNIT
UNPACKING
CAUTION: EQUIPMENT DAMAGE
THIS UNIT HAS BEEN SHIPPED WITHOUT OIL.
Failure to maintain the engine oil at the proper level
will result in serious engine damage.
When you unpack your new engine-generator set be
sure to remove all the information sheets and manuals from the carton.
Oil is added to the engine by removing the oil fi ll cap
and adding oil at this point. After fi lling the crank-
case to the proper level, be sure you properly tighten
the oil fi ll cap. NOTE: This engine generator must
be on a level surface before you check or add oil to
the system.
OIL FILLER CAP/DIPSTICK
OIL FILL HOLE
(bottom edge)
The necessity of using the correct oil, and keeping
the crankcase full cannot be overemphasized. Engine failures resulting from inadequate or improper
lubricant are considered abuse and not covered by
the generator or engine manufacturer’s warranty.

Oil Recommendations
Outdoor temperatures determine the proper oil
viscosity for the engines. Use the chart to select the
best viscosity for the outdoor temperature range
expected.
