"HOW-TO" MAINTENANCE

ENGINE OIL CHANGE

■

Initial oil change

■

Thereafter

OIL DRAIN PLUG

(ON BOTH SIDE)

1. When changing oil, stop the engine and loosen the drain plug.

2. Re-install the drain plug before refilling oil.

3. Refer to the recommended oil table on page 11.

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

OIL CAPACITY : 1.55 L (1.36 lmp qt,

1.64 US qt)

OIL FILLER CAP

ENGINE OIL FILTER

REPLACEMENT

■

Initial engine oil filter replacement should be performed after 20 hours of operation. Thereafter replace the engine oil filter every 200 hours.

OIL FILTER

■

When installing a new oil filter, apply oil to O-ring, attach the oil filter in position and tighten 2/3 turns by hand or with wrench after touching the O-ring to the sealing surface of engine.

■

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

CAUTION :

To prevent injury, pay attention to the spilled hot engine oil when replacing engine oil filter.

SPARK ARRESTER

SPARK ARRESTER

In 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 and regulations 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.

MUFFLER

How to remove the spark arrester

1. Remove the flange bolts from the muffler cover and remove the muffler cover.

2. Remove the special screw from the spark arrester and remove the spark arrester from the muffler.

ARRESTER

SCREEN

SPARK ARESSTER SCREEN

Clean the spark arrester screen

Use a brush to remove carbon deposits from the spark arrester screen.

Be careful to avoid damaging the screen.

The spark arrester must be free of breaks and holes. Replace the spark arrester if it is damaged.

Install the spark arrester, and muffler protector in the reverse order of disassembly.

PREPARATION FOR STORAGE

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

■

Drain fuel from fuel tank and strainer

(cup) carefully by disconnecting the fuel line. Gasoline left in the fuel tank will eventually deteriorate making engine-starting difficult.

Screw for Drain

■

Drain fuel from the carburetor by loosening the drain screw on the carburetor float chamber , or run the engine at no-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 available. NEVER USE WATER TO CLEAN GENERATOR !

■

Store generator in a well ventilated, low humidity area.
