WARRANTY QUESTIONS AND ANSWERS
Q. What costs are my responsibility during the
warranty period?
A. The customer’s responsibility includes all
costs of normal maintenance service, nonwarranty repairs, accident damages, as well
as oil and spark plugs.
Q. What are some examples of “abnormal” strain,
neglect, or abuse?
A. These terms are general and overlap each
other in areas. Specific examples include:
Running the machine out of oil; lack of proper
maintenance; operating the machine with a
broken or damaged part which causes another part to fail; and so on. If you have any
specific questions on operation or maintenance, please contact your dealer for advice.
Q. Does the warranty cover incidental costs such
as transportation due to a failure?
A. No. The warranty is limited to repair of the
machine itself.
Q. May I perform any or all of the recommended
maintenance shown in the Owner’s Manual
instead of having the dealer do them?
A. Yes, if you are a qualified mechanic and follow
the procedures specified in the Owner’s and
Service Manual. We do recommend, however,
that items requiring special tools or equipment
be done by a Yamaha generator dealer.
Q. Will the warranty be void or cancelled if I do
not operate or maintain my new Yamaha
exactly as specified in the Owner’s Manual?
A. No. The warranty on a new Yamaha cannot
be “voided” or “cancelled.”
However, if a particular failure is caused by
operation or maintenance other than as
shown in the Owner’s Manual, that failure
may not be covered under warranty.
Q. What responsibility does my dealer have
under this warranty?
A. Each Yamaha generator dealer is expected
to:
1. Check the operation of the generator
before sale.
2. Explain the operation, maintenance, and
warranty requirements to your satisfaction
at the time of sale, and upon your request
at any later date.
In addition, each Yamaha generator dealer is
held responsible for his setup, service and
warranty repair work.
Q. Is the warranty transferable to second owners?
A. Yes. The remainder of the existing warranty
can be transfered upon request.The unit has
to be inspected and reregistered by an authorized Yamaha generator dealer for the policy
to remain effective.
CUSTOMER SERVICE

741-040a
Before the generator can be connected to a building’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the building’s main fuse box. The switch is the connection
point for generator power and allows selection of
generator or main line power to the building. This
will prevent the generator from charging the main
power line (backfeeding) when the main power
supply has failed or has been turned off for line
repair. Backfeeding can electrocute or injure line
maintenance personnel. Also, generator and building electrical system damage can occur when normal operating power returns if unit is used without
an isolation switch.
AE00086
EXTENSION CORD NOTES
9 When using an extension cord, its total length
should not exceed
 60 meters for cross section of 1.5 mm square
 and
 100 meters for cross section of 2.5 mm square.
9 This extension cord should be protected by a
tough flexible rubber sheath (IEC 245) or the
equivalent to withstand mechanical stresses.

OIL WARNING SYSTEM
When the oil level falls below the lower level, the
engine stops automatically. Unless you refill with oil,
the engine will not start again.
NOTE:
If the engine stalls or does not start, turn the engine
switch to "ON" position and then pull the recoil starter.
If the oil warning light flickers for a few seconds, the
engine oil is insufficient. Add oil and restart.

(for YG4000D/YG5200D/YG6600D/YG6600DE)
The G.F.C.I. (Ground Fault Circuit Interrupter) 1 shuts
off power to the protected receptacles if a ground fault
(electrical leak) is detected.
If the reset button 2 pops out 3, the equipment
plugged into the receptacle may be faulty. If this happens, check the equipment carefully. If the equipment
appears to be in good condition, press the reset button
firmly until a click is heard. This will restore power. If
the reset button pops out again, unplug the equipment
immediately. Have the equipment inspected and
repaired by a qualified repairperson before attempting
to use it again.
w
TO REDUCE THE CHANCE OF ELECTRICAL
SHOCK:
9 Do not attempt to operate equipment if the
ground fault circuit interrupter reset button
pops out repeatedly during use.
9 Test the ground fault circuit interrupter during
the pre-operation checks according to the
maintenance instructions on page 35.
9 Remember that only receptacles labeled
“GFCI” have ground fault circuit interrupter
protection.

AIR FILTER
1. Remove the air filter cover and element.
2. Wash the element in solvent and dry.
3. Oil the element and squeeze out excess oil.
The element should be wet but not dripping.
q
Recommended oil:
Foam-air-filter oil
or
SAE #20 motor oil
cC
Do not wring out the element.
This could cause it to tear.
710-058a
NOTE:
For EF4000DE/YG4000D, the dry foam urethane
(sponge) 1 is installed to absorb any excessive oil
that comes out of the air filter element. Therefore do
not apply oil to the sponge 1. If it gets oily, squeeze
out the oil.
B
4. Insert the element into the air filter.
NOTE:
Be sure the element sealing surface matches the air
filter so there is no air leak.
cC
The engine should never run without the element;
excessive piston and cylinder wear may result.
w
Never use solvent while smoking or in the vicinity
of an open flame.

1. Remove the spark plug, pour about one tablespoon of SAE 10W30 or 20W40 motor oil into the
spark plug hole and reinstall the spark plug. Recoil
start the engine by turning over several times (with
ignition off) to coat the cylinder walls with oil.
2. Pull the recoil starter until you feel compression.
Then stop pulling. (This prevents the cylinder and
valves from rusting).
3. Clean exterior of the generator and apply a rust
inhibitor.
4. Store the generator in a dry, well-ventilated place,
with the cover placed over it.
5. The generator must remain in a vertical position
when stored, carried or operated.
