INTERRUPTER RECEPTACLE
GENERATOR
FEATURES
All models have a 120-volt ground fault
circuit interrupter (GFCI) receptacle. The
GFCI receptacle is on the control panel or top
coverofalternator(MGR2900A). The GFCI
protects you against hazardous electrical
shock caused when your body becomes a
path through which electricity travels to
reach ground. This could happen when
you touch an appliance or cord that is ‘live’
through faulty mechanism, damp or worn
insulation, etc.
OIL ALERT SYSTEM
Theoilalertsystemprotectstheenginefrom
low oil damage. This system automatically
shuts down the engine and prevents engine
restarting if the oil level falls too low.
120 VOLT ONLY: This position sends full
power to the 120V receptacles only. 240V
power is not available. Use this position
when powering 120V items only.
Note:Whenthishappens,theengineswitch
remains in the ON position. The oil alert
system is wired into the ON/OFF Switch.
120 + 240 VOLT: This position sends full
power to the 120/240V receptacle. It also
powers the 120V receptacles at reduced
wattage capacity.
If this system shuts down the engine, the
engine will not start until you add oil. Add
oil to engine (see Engine Oil, page 7).
When protected by the GFCI, you may still
feel a shock, but the GFCI should cut it off
quickly. A person in normal health should
notreceiveseriousinjury. Note:Infantsand
very small children may still be affected.

AUTO-IDLE SYSTEM
(Except Model MGR2900A)
TheAuto-IdleSystemallowstheenginetoidle
down or run at a slower speed when the gen-
erator is not being used to supply power. The
Auto-idlesystemcanbeturnedONorOFFby
arockerswitchonthecontrolpanel.Whenthe
switch is in the OFF position, the engine runs
at full speed all of the time. When the switch
is in the ON position, the engine slows down

When a load is applied to the generator (an
electricalitemispluggedinandturnedon)the
engine speeds up to the preset speed required
to produce the correct voltage.
2. If the GFCI receptacle tests okay,
restore power by pushing the RESET
button back in. The test lamp should
work at this time. IMPORTANT: You
must press the RESET button firmly
and fully. It should lock into place. If
the GFCI does not lock into place, do
not use receptacle. Contact a qualified
electrician for repairs.
IMPORTANT: A minimum current load
of 1 Amp is required to disengage the auto
idle solenoid and cause the engine to come
up to speed for correct voltage. Powering
items at reduced engine speed will damage
generator and powered items.

3. Electric motors present a special prob-
Note: Some motors require nearly the
same wattage to run as to start. These
items include saws, drills, hair dryers,
and food mixers. See Chart 1 for typical
appliance wattage examples.
DETERMINING
lem. They require up to three-times
their rated wattage to start. Chart 2, be-
low, shows starting watts for different
size motors. For example: an electric
motor nameplate states 5 amps at 120
volts. 5 amps x 120 volts = 600 watts
running. Multiply this figure by 3. This
will show the starting watts needed. 600
watts x 3 = 1800 watts to start. When
figuring the generator load for motors,
you must use the starting watts figure.
Do not use the running watts figure.
ELECTRICAL LOAD
FOR GENERATOR
You must decide what electrical load your
generator can power. Do this before us-
ing generator. Use the following four-step
method. It will help you select a load that
is not too large. Make sure total wattage of
all electrical loads does not exceed rated
wattage of generator. For rated wattage of
your generator, see Specifications, page 5.
Electric motors present a special problem
when figuring load. Read Step 3 carefully.
4. Add watts and starting watts of all
items. This total must not be larger than
the rated wattage of your generator.
It is a good idea to have up to 25%
extra capacity for future needs or extra
equipment.
Chart 1 - Typical Electric Appliance Wattages
1. Make two lists of items you want pow-
ered by generator. List all motors and
motorpoweredappliancesinone. Listall
lights, small appliances, etc. in the other.
For standby service to home or building,
only include items you must power.

2. Enter running watts of each item except
motors. The light bulb or appliance
nameplate lists its wattage. Remem-
ber, 1KW = 1000 watts. Note: The
nameplate may not list wattage. It may
only list volts and amps. The formula
for finding wattage is: Volts x Amps
= Watts. For example: An appliance
nameplate states 3 amps at 120 volts.
3 amps x 120 volts = 360 watts.

2. Let engine run for two or three minutes
after removing electrical loads. This
lets engine cool slightly.
CAUTION: The engine speed
is preset. The throttle is locked
in preset position. Do not adjust
throttle. Preset position lets en-
gine run at 3600 RPM under load.
The engine must maintain 3600

Note: The wattage ratings for some
electrical motors are misleading. They
may require up to three-times their
rated wattage to start. You must figure
total electrical load wattage. Make sure
total wattage of all electrical loads does
not exceed rated wattage of generator.
See Determining Electrical Load For

WARRANTY INFORMATION
KEEP THIS WARRANTY

Date Purchased
Always specify model and serial numbers when communicating with the factory.
We reserve the right to amend these specifications at any time without notice. The only warranty applicable is our standard
written warranty. We make no other warranty, expressed or implied.
FIVE-YEAR LIMITED WARRANTY
GASOLINE PORTABLE GENERATORS
DESA Specialty Products™ makes no warranty with respect to the engine and engine components not of its manufac-
ture. They are subject to warranties of their manufacturers. Robin warrants the engine. See engine owner’s manual for
engine warranty information.
DESA Specialty Products™ warrants each generator, excluding engine, of its manufacture, to be free from defects in
material and workmanship for five years from the date of first purchase from an authorized dealer, provided that the
product has been properly installed, maintained, and operated in accordance with all applicable instructions. The bill
of sale or proof of purchase must be presented at the time a claim is made under this warranty.
This warranty is extended only to the original retail purchaser. This warranty covers only the parts and labor required
to restore this unit to its proper operating condition. Warranty parts must be obtained through factory authorized deal-
ers and service centers for this product. These dealers and service centers will provide original factory replacement
parts. Failure to use original factory replacement parts voids this warranty.
This warranty does not apply to parts that are not in original condition because of normal wear and tear, or parts that
fail or become damaged as a result of misuse, abuse, negligence, accident, lack of proper maintenance, alteration,
modification, tampering, contaminated fuels, repair using improper parts, or repair by anyone other than an authorized
dealer or service center. Routine maintenance is the responsibility of the owner. Travel, handling, transportation, and
incidental costs associated with warranty repairs are not reimbursable under this warranty and are the responsibility of
the owner.
To the full extent allowed by the law of the jurisdiction that governs the sale of the product, this express warranty
excludes any and all other expressed warranties and limits the duration of any and all implied warranties, including war-
ranties of merchantability and fitness for a particular purpose to five years from the date of first purchase, and DESA
Specialty Products’™ liability is hereby limited to the purchase price of the product and DESA Specialty Products™
shall not be liable for any other damages whatsoever including indirect, incidental, or consequential damages.
Some states do not allow limitation of how long an implied warranty lasts or an exclusion or limitation of incidental
or consequential damages, so the above limitation of damages may not apply to you.
This warranty provides the original purchaser with specific rights. For information regarding those rights, please con-
sult the applicable state laws.
