VALVE CLEARANCE

Intake — 0.08-0.12 mm (.003-.005 inch)

Exhaust — 0.13-0.17 mm (.005-.007 inch)

After the first 50 hours of operation, check the valve clearance in

the engine and adjust if necessary.

NOTICE: If unsure about doing this procedure or the proper tools are

not available, take the generator to the nearest service center to have

the valve clearance adjusted. This is a very important procedure to

ensure longest life for the engine.

SPARK ARRESTER SCREEN

Remove screen every 50 hours for cleaning and inspection.

Replace if damaged.

Clean and inspect the spark arrester as follows:

1. Remove the screen retainer by removing the retainer clamp.

2. Remove the retainer screw from the muffler outlet tube.

3. Slide the spark arrester screen out from the muffler outlet tube.

4. Be careful not to damage the spark arresting screen. The

spark arrester must be free of breaks and holes. If screen

is not damaged, clean it with a commerical solvent.

5. Replace the screen and retainer and secure with retainer screw

and clamp.

GENERATOR: Brushes

The brushes in the generator should be inspected once every year

for chips and cracks. Brushes should be replaced when they are worn

to 1/4 inch (7mm).

NOTE: Replace brushes in sets only, never separately.

Replace only with brushes specified in parts list. Other brushes

may appear to be identical but may have completely different

mechanical and electrical characteristics.

INSPECTING THE BRUSHES:

1. Remove 2 screws (V) and end cover (W).

2. Remove screw (X) holding the brush module (Y).

3. Disconnect the blue (+) and yellow (-) brush wires from the

tabs.

4. Replace if worn to 1/4 inch (7mm).

5. Do not over tighten screw.

HEAT SHIELD:

Inspect to ensure that all heat shields and heat deflectors are intact

and in place. Do not remove any parts or modify parts. Removing or

modifying parts could cause serious damage to the unit.

ENGINE: Carburetor Icing

During the winter months, rare atmospheric conditions may

develop which will cause an icing condition in the carburetor. If this

develops, the engine may run rough, loose power, and may stall. Call

Product Service for more information.

QUICK STARTING TIPS FOR UNITS THAT HAVE BEEN

SITTING FOR AWHILE:

If your unit has been sitting around for a long time period and is

hard to start, try doing some of these easy steps before calling the

Customer Hotline.

1. Check the oil level.

2. Check or replace the LP Gas tank.

3. Change the spark plug.

4. Check the fuel lines. Make sure the fuel shut off valve is open.

5. Check all generator parts for integrity.

6. Clean the Carburetor.

INFREQUENT SERVICE

If the unit is used infrequently, difficult starting may result. To

eliminate hard starting, follow these instructions:

1. Run the generator at least 30 minutes every month.

2. Run the generator, then close the fuel shut-off valve and allow

the unit to run until the engine stops.

3. Move the engine switch to the “OFF” position.

LONG TERM STORAGE

When the generator set is not being operated or is being stored

more than one month, follow these instructions:

1. Replenish engine oil to upper level.

2. Run the generator, then close the fuel shut-off valve and allow

the unit to run until the engine stops.

3. Move the engine switch to the “OFF” position.

4. Pour about one teaspoon of engine oil through the spark plug

hole, pull the recoil starter several times and replace the plug.

Then pull the starter until you feel the piston is on its

compression stroke and leave it in that position. This closes

both the intake and exhaust valves to prevent the inside of the

cylinder from rusting.

5. Cover the unit and store in a clean, dry place that is well

ventilated away from open flame or sparks.
