1. brush type
The brushes in the generator should be inspected once every year for chips and
cracks. Brushes should be replaced when they are over worn.
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.
2. exciting the generator
•
Brush type
If there is a loss of residual magnetism (voltage will not build up), especially if
your unit has been sitting around for a long time period or due to vibration during
shipping, it may be necessary to re-excite the unit.
This can be accomplished using a 6, 9-Volt lantern battery ( dry cell ) or a 12-
Volt automotive battery. Disconnect all loads from generator. With the generator
running, touch a lead connected from the positive battery terminal to the positive
brush terminal, and a lead from the negative battery terminal to the negative
brush terminal. The DC voltage fed through the rotor windings should restore
magnetism. If the generator does not show any output after flashing the field,
refer to the troubleshooting section for the generator.
Even if small permanent magnets are built into the rotors in order to insure the
presence of a residual magnetic field. Occasionally, even these units will require
flashing (re-exciting) due to the “permanent “ magnet losing its magnetism.

CLeANING
1.Remove the cup at the bottom
of the fuel valve with a small
wrench.
2.Remove the fuel valve filter.
3.Clean and wash out the filter and
cup and replace.

1.Remove the plastic fuel strainer,
located below the fuel tank cap.
2.Wash the strainer in solvent (1) and
replace (3).
