Powermate PM0558023.01 - Manual (Page 11)

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 (A).
2. Remove 4 stator bolts (B)
and endbell.
3. Disconnect the green (-) or
blue (+) brush wires from
the tab.
4. Remove brush mounting
screws (C).
5. Slide brushes (D) 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
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. Attach the "-" lead of the
battery to the negative
brush. Very briefly, touch
the "+" lead of the battery to
the positive brush as
shown.
4. Replace the brush cover,
tip the generator to an
upright position and start the engine. Measure output
voltage by using a plug-in voltmeter. If voltage is not
present, turn the engine off and repeat the excitation
procedure.
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.
WARNING: If a deflector is used, it must be
made of metal.
BATTERY MAINTENANCE
Read all cautions and warnings provided by the battery
manufacturer before doing maintenance on your battery.
For Batteries with Filler Openings: Check battery fluid
level by removing the filler caps. If necessary, fill the battery
with distilled water to the indicator fill level only.
Use a terminal post brush to clean the battery terminal
posts and terminals. Good, clean terminals are necessary for
good contact.
ENGINE MAINTENANCE
NOTE: Refer to the engine manufacturer's manual for
service and maintenance of the engine.
