Koshin GEH-3100DX Instructions page 11

This manual has been prepared to acquaint you with the operation and maintenance of this product. Study the
information provided carefully to avoid problems associated with improper application or maintenance. Upon
receipt of your generator, verify that it is complete and in good condition.
The generator is comprised of a 4 stroke, air-cooled engine directly coupled to a 2 pole alternator producing
either 125VAC or 125/250VAC depending on model. The no-load speed is approximately 3750rpm with the
speed under load going to approximately 3600rpm thus producing a frequency of 60Hz.
INITIAL INSPECTION
Upon receiving your generator set, inspect the product to
make sure it is complete and in good condition. Handle
with care and place in a suitable site for storage or
operation.
GROUND CONNECTION
The generator can be grounded to earth to reduce the
chance of electrical shock. To do this you will need a
grounding rod and an appropriately sized copper ground
wire. Drive the ground rod into the earth, connect one end
of the copper wire to the rod and connect the other end to
the external ground connection on the generator set. This
is a general explanation, consult National and Local
electrical codes to ensure compliance.
BEFORE START-UP
ENGINE FUEL
Use Unleaded Gasoline with minimum Octane 86. Check
the fuel gauge beside the fuel fill and add as necessary.
ENGINE OIL
The engine manual or other information provided by the
engine manufacturer supersedes data provided here.
Proper oil grade varies with climate. The grade listed in
the table is typically a good grade but consult the engine
manual to verify proper grade. The oil fill ports are located
on both sides of the engine. The gray filler cap has an
integral dipstick. Add the proper amount of oil and check
the level using the dipstick. NOTE: The dipstick should be
placed into the filler opening but not screwed in to check
the level.
