PORTABLE GASOLINE GENERATORS
MAINTENANCE
AND REPAIRS
WARNING: Only a qualified
electrical service person should
service and repair the alternator
on this generator. Use only factory
approved replacement parts.
HIGH ALTITUDE OPERATION
This generator will not perform well at high
altitudes without proper adjustment. See
engine owner’s manual for details.
ADDING ELECTRICAL
LOADS
IMPORTANT: Do not overload generator.
Make sure total wattage of all electrical loads
does not exceed rated wattage of generator.
Overloading may shorten generator life. It
could also cause internal damage to genera
-
tor. Overloading will trip circuit breaker.
IMPORTANT: (All models except HWI3000,
MGH3000, MGH3000PR, MGH6500IE, and
MGH10000A) Keep full power selector switch
in the 120 VOLT ONLY position if only power
-
ing 120V items. Only move switch to 120/240
VOLT position if powering 240V items.
1. Check items to be powered. Their
nameplate lists their wattage ratings.
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
Generator, page 10.
2. Start engine. Let engine reach full
speed.
3. Connect electrical loads one at a time.
If the load consists of electric motors,
start them first. Always start the largest
first. Start each motor individually.
DISCONNECTING ELECTRIC
LOADS
Remove electrical loads one at a time. Re-
move voltage sensitive items first. Voltage
sensitive items include TVs, VCRs, and other
home electronic items.
STOPPING ENGINE
IMPORTANT: The engine speed is preset.
The throttle is locked in preset position. Do
not adjust throttle.
Follow the steps below to stop engine.
1. Remove all electrical loads from gen-
erator (see Disconnecting Electrical
Loads). Remove electrical loads one
at a time.
2. Let engine run for two or three minutes
after removing electrical loads. This
lets engine cool slightly.
3. Turn engine switch to the OFF position
(see Figure 29).
4. Turn fuel valve lever off except on
Model MGH3000PR. Do this by mov-
ing valve lever fully to the left (see
Figure 30).

IMPORTANT: Keep generator level when
servicing. Never turn generator upside down
or stand it on end to service.
Note: We supply the engine owner’s manual
with generator. Refer to that manual for
questions concerning engine maintenance
and repairs.
Non-engine parts require little maintenance.
Keep generator clean. Use a damp cloth to
clean outside surfaces. Never use water to
clean generator. Water can cause damage to
internal parts. Use vacuum to clean air inlet
and outlet louvers of alternator.
CAUTION: Shut off generator
before performing maintenance.
CAUTION: The engine speed
is preset. The throttle is locked
in preset position. Do not adjust
throttle. Preset position lets
engine run at 3600 RPM under
load. The engine must maintain
3600 RPM for generator to create
correct voltage. Running engine
at lower speeds will damage gen
-
erator and powered items.
