(Off Position)
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 9.
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 larg-
est 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 min-
utes after removing electrical loads.
This lets engine cool slightly.
3. Move engine lever or turn engine switch
to the OFF position (see Figure 24).
4. Turn fuel valve lever off except model
MGH3000PR. Do this by moving valve
lever fully to the left (see Figure 25).

MAINTENANCE
AND REPAIRS
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 en-
gine run at 3600 RPM under load.
The engine must maintain 3600
RPM for generator to create cor-
rect voltage. Running engine at
lower speeds will damage gen-
erator and powered items.
WARNING: Only a qualified
electrical service person should
service and repair the alternator
on this generator. Use only fac-
tory approved replacement parts.
