Powermate PM0478022 manual Maintenance Service Information, Inspecting the Brushes, Heat Shield

MAINTENANCE SERVICE INFORMATION

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 (L).

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

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

4.Remove brush mounting screws (M).

5.Slide brushes (N) from holders.

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

7.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:

NOTE: If your generator is a brushless unit please contact your local service center or the Coleman Powermate Service Department for assistance with exciting your 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).

2.Remove the brush cover.

3.Start the engine with no load connected to the generator.

4.Attach the "-" lead of the battery to the negative brush. Very briefly, touch the "+" lead of the battery to the positive brush as

shown. Remove as soon as voltage builds up. To measure voltage, use a plug-in voltmeter.

HEAT SHIELD:

Inspect to ensure that all heat shields and heat deflectors are intact and in place.

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. This temporary condition can be overcome by deflecting some of the hot air from the engine over the carburetor area.

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