specified level as directed on page 6.
If contaminated or deteriorated oil is used or the
GB
quantity of the engine oil is not sufficient, the
GB
engine damage will result and its life will be
GB
greatly shortened.

4. CHECKING CARBON BRUSH
(See Fig. 5 5 -t t )
If the brush become excessively worn, its contact
pressure with the slip ring changes and causes a
roughened surface on the slip ring, resulting in
irregular generator performance.
Check the brush every 500 hours or if generator
performance is irregular.
If the brush is 5 mm long or less, replace it with a
new one.

(b) Carefully note the brush direction and relative
position with the slip ring when installing new
brush.
9. PERIODIC OPERATION AND
INSPECTION
When furnishing the generator as emergency
electric power source, periodic operation and
inspection are needed.
Fuel (gasoline) and engine oil will be deteriorated
with time, and this causes that the engine is
difficult to start and as the results improper
engine operation and fault.
CAUTION
Since the fuel (gasoline) will be deteriorated
with time, replace fuel (gasoline) with fresh
one periodically; once every three (3)
months is recommended.
