Periodic Maintenance Schedule table

*Note 1 : Initial oil change should be performed after first twenty (20) hours of operation.Thereafter change oil every hundred (100) hours. Before changing oil, check for a suitable way to dispose of old oil. Do not pour it down into sewage drains, onto garden soil or into open streams.Your local zoning or environmental regulations will give you more detailed instruc-tions on proper disposal.

*Note 2 : As to the procedures for these items, please refer to the SERVICE MANUAL orconsult your nearest Yamaha dealer.

*Note 3 : More frequent oil changing, oil filter replacement and air cleaner service onreplacement may be necessary depending on operating conditions.This would include dusty environment, high ambient temperature, heavy engineloading.

OIL FILTER

ENGINE OIL CHANGE■ Initial oil change

・・・・・After 20 hours of operation

■ Thereafter・・・・・Every 100 hours of operation

1. When changing oil, stop the engine andloosen the drain plug.

2. Re-install the drain plug before refillingoil.

3. Refer to the recommended oil table onpage 11.

4. Always use the best grade and cleanoil. Contaminated oil, poor quality oiland shortage of oil cause damage toengine or shorten the engine life.

OIL CAPACITY : 1.55 L (1.36 lmp qt,1.64 US qt)

ENGINE OIL FILTERREPLACEMENT■ Initial engine oil filter replacement

should be performed after 20 hours ofoperation. Thereafter replace the engineoil filter every 200 hours.

■When installing a new oil filter, apply oilto O-ring, attach the oil filter in positionand tighten 2/3 turns by hand or withwrench after touching the O-ring to thesealing surface of engine.

■Run the engine for a minute ; stop theengine and check for oil leakage aroundthe oil filter and recheck the oil level.

SPARK ARRESTER

-32 -

SPARK ARRESTERIn a dry or wooded area, it is recommendable to use the engine with a spark arrester.Some areas require the use of a spark arrester. Please check your local laws andregulations before operating your engine.

The spark arrester must be cleaned regularly to keep it functioning as designed. A clogged spark arrester :

● Prevents the flow of exhaust gas ● Reduces engine output ● Increases fuel consumption●Makes starting difficult

If the engine has been running, the muffler and the spark arrester will be very hot.Allow the muffler to cool before cleaning the spark arrester.

How to remove the spark arrester1. Remove the flange bolts from the

muffler cover and remove the mufflercover.

2. Remove the special screw from thespark arrester and remove the sparkarrester from the muffler.

PREPARATION FOR STORAGE

-33 -

The following procedures should be followed prior to storage of your generator fora period of 6 months or longer.

■ Drain fuel from fuel tank and strainer(cup) carefully by disconnecting thefuel line. Gasoline left in the fuel tankwill eventually deteriorate makingengine-starting difficult.

■ Drain fuel from the carburetor by loos-ening the drain screw on the carburetorfloat chamber , or run the engine atno-load until it stops.

■ Disconnect the terminal of the battery.

■ Change engine oil.

■ Check for loose bolts and screws, tighten them if necessary.

■ Clean generator thoroughly with oiled cloth. Spray with preservative if avail-able. NEVER USE WATER TO CLEAN GENERATOR !

■ Store generator in a well ventilated, low humidity area.

"HOW-TO" INSTALL THE WHEEL(1) Checking of supplied accessories

(2) Tool preparation

■ Hoist or square bar (100 mm (3.94 in) by 100 mm (3.94 in), length : 700 mm (27.56 in))

■ Plier

■ Spanner or socket wrench (12 mm (0.472 in)), 2 units

(3) Installation procedures

(a) Raise the generator by about 100 mm (3.94 in), with hoist or with square bar put underthe bottom panel.

(b) Attach wheel mounting parts ① ,② ,stopper ⑨ , using clamp ⑩, ⑧ and wheel ③, towheel shaft ④.Then check that wheel ③ is rotated smoothly. If moving turns out to be too compli-cated, assemble them together using grease. (4 locations / 2 pieces)

(c) Bend the tip of ① according to the shape of wheel shaft ④ as possible.

(d) Attach the assembled shaft to the foundation plate of the engine, using ⑤, ⑦, and ⑧.
