The National Electric Code requires the frame and
external electrically conductive parts of generator be
properly connected to approved earth ground.
Local electrical codes may also require proper
grounding of this unit. For that purpose, a
GROUNDING WING NUT (Figure 1) is provided on the
frame of your unit.
Generally, connecting a No. 12 AWG (American Wire
Gauge) stranded copper ire to the grounding ing
nut and to an earth-driven copper or brass grounding
rod (electrode) provides adequate protection against
electrical shock.
Ho ever, local codes may vary idely. Consult ith a
local electrician for grounding requirements in your
area. Be sure to keep the ground ire attached hile
you connect the electrode.
Properly grounding the generator helps prevent
electrical shock if a ground fault condition exists in the

DONT OVERLOAD THE
GENERATOR
Overloading a generator in excess of its rated attage
capacity can result in damage to the generator and/or
connected electrical devices. Observe the follo ing, to
prevent overloading the unit:
 Add up the total attage of all electrical devices to
be connected at one time. This total should NOT be
greater than the generators attage capacity.
 If the appliance, tool or motor does not give attage,
multiply 120 Volts times ampere rating to determine
atts (volts x amps = atts).
 The rated attage of lights can be taken from
attage listed on the light bulbs. The rated attage
of tools, appliances and motors can usually be found
on a data plate or decal affixed to the device. Use
Figure 13 belo as a general reference.
 Some electric motors, such as induction types,
require about three times more atts of po er for
starting than for running. This surge of po er lasts
for only a fe seconds hen starting such motors.
Be sure you allo for this high starting attage
hen selecting electrical devices to connect to your
generator. First figure the atts needed to start the
largest motor. Add to that figure the running atts of
all other connected loads.

GENERAL MAINTENANCE
RECOMMENDATIONS
The o ner/operator is responsible for making sure that
all periodic maintenance tasks are completed on a
timely basis; that all discrepancies are corrected; and
that the unit is kept clean and properly stored. Never
operate a damaged or defective generator.
Engine Maintenance
See engine manual for instructions.
Generator Maintenance
Generator maintenance consists of keeping the unit
clean and dry. Operate and store the unit in a clean dry
environment here it ill not be exposed to excessive
dust, dirt, moisture or any corrosive vapors. Cooling air
slots in the generator must not become clogged ith
sno , leaves or any other foreign material.
Check the cleanliness of the generator frequently and
clean hen dust, dirt, oil, moisture or other foreign
substances are visible on its exterior surface.
NOTE: Do Not use a garden hose to clean generator.
Water can enter engine fuel system and cause
problems. In addition, if ater enters generator through
cooling air slots, some of the ater ill be retained in
voids and cracks of the rotor and stator inding
insulation. Water and dirt buildup on the generator
internal indings ill eventually decrease the
insulation resistance of these indings.
Clean the Generator
 Use a damp cloth or soft bristle brush to ipe
exterior surfaces clean.
 A vacuum cleaner may be used to pick up loose dirt
and debris.
 Lo pressure air (not to exceed 25 psi) may be used
to blo a ay dirt. Inspect cooling air slots and
opening on generator. These openings must be kept
clean and unobstructed.
SERVICE/ADJUSTMENTS
Refer to engine o ners manual for information.
STORAGE
The generator should be started at least once every
seven days and allo ed to run at least 30 minutes.
If this cannot be done and you must store the unit for
more than 30 days, use the follo ing guidelines to
prepare it for storage.
Generator Storage
 Clean the generator as outlined in To Clean the
Generator.
 Check that cooling air slots and openings on
generator are open and unobstructed.
 Disconnect the negative battery cable from the
battery.
DANGER: Storage covers can be flammable.
Do Not place a storage cover over a hot
generator. Let the unit cool for a sufficient time
before placing the cover on the unit.
Engine Storage
See engine o ners manual for instructions on ho to
properly store the engine.
Other Storage Tips
Do Not store gasoline from one season to another.
