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
