BREAK-IN PROCEDURE
Controlled break-in helps insure proper engine and gener-
ator operation. Follow engine procedure outlined in engine
manual.
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.
4.
Plug a lamp or light into the generator before starting the
engine. The light source will illuminate when voltage has
returned.
5.
Start the engine with no load connected to the generator.
6.
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. 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)
MAINTENANCE
Do not apply heavy electrical load during break-in
period (the first two to three hours of operations).
