manual.	5.	Start the engine with no load connected to the generator.
	6.	Attach the "-" lead of the battery to the negative brush.

Do not apply heavy electrical load during break-in period (the first two to three hours of operations).

MAINTENANCE

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.

INSPECTING THE BRUSHES:

1.Remove cover plate (R).

2.Remove 4 stator bolts (U) and endbell.

3.Remove screws holding the protective plate on the inside of the endbell.

4.Disconnect the green (-) or blue (+) brush wires from the tab.

5.Remove brush mounting screws (S).

6.Slide brushes (T) from holders.

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

8.Do not over tighten screws.

NOTE: Replace only with brushes specified in parts list. Other brushes may appear to be identical but may have completely different mechanical and electrical characteristics.

EXCITING THE GENERATOR:

If there is a loss of residual magnetism (voltage will not build up), it may be necessary to re-excite the unit.

1.Use a 6-volt lantern battery (dry cell) or a 12-volt automotive battery.

2.Disconnect all loads from generator.

3.Remove the brush cover.

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.

NOTE: Refer to the engine manufacturer's manual for service and maintenance of the engine.

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.Replace the old fuel.

3.Change the spark plug.

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

5.Check all generator parts for integrity.

6.Clean the Carburetor. (See engine manual for service centers)
