Maintenance and Repairs
Only a qualified
electrical service
person should service and repair the
alternator on this generator. Use only
factory approved replacement parts.
You must always
run the engine at
full speed. Do not run engine at lower
speeds. At full speed, the engine runs
at 3600 RPM under load. The engine
must maintain 3600 RPM for generator
to create correct voltage. Running
engine at lower speeds will damage
generator and powered items.
Shut off generator
before performing
maintenance.
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.

ENGINE MAINTENANCE
Periodic checks and maintenance are very
important for keeping the engine in good
condition and durable. The chart on page
18 indicates which checks to make and
when to make them. The mark “•”
indicates that special tools and skills are
required. Items marked “•” should be
serviced by an authorized Yanmar dealer,
unless the owner has the proper tools and
is mechanically proficient.
Consult your Yanmar dealer.
Shut off the
engine before
performing any maintenance. If the
engine must be run, make sure the area
is well ventilated. The exhaust contains
poisonous carbon monoxide gas.
After the engine
has been used,
clean the engine immediately with a
cloth to prevent corrosion and to
remove sediment.
Only use genuine
Yanmar parts. The
use of replacement parts which are
not of equivalent quality may damage
the engine.
HOW TO CHANGE YOUR ENGINE OIL
Remove the oil filler cap. Remove the drain
plug and drain the old oil while the engine
is still warm. The plug is located on the
bottom of the cylinder block. Tighten the
drain plug and refill with the recom-
mended oil. (See the section under
“Preparations for Starting” in the engine
owner’s manual.)
CLEANING THE OIL FILTER
Loosen the fixing bolt and then pull out
the oil filter. Clean oil filter every six
months or 500 hours of operation.
CHANGING THE AIR CLEANER ELEMENT
Do not wash the air cleaner element with
detergent because this is a wet-type
element. Change air cleaner element every
six months or 500 hours of operation (or
earlier if dirty).
See the section for changing the air
cleaner element under “Preparations for
Starting” in the engine owner’s manual.
Never run the
engine without
the air cleaner element or with a
defective element.
NOTE: A clogged element hinders the
flow of air to the combustion chamber.
This reduces engine output, increases lube
oil and fuel oil consumption and makes
starting difficult. Make sure you clean your
