9. "HOW-TO" MAINTENANCE
(See Fig.
55
)
The following procedures should be followed
prior to storage of your generator for periods of 6
months or longer.
Drain fuel from fuel tank carefully by
disconnecting the fuel line.
Gasoline left in the fuel tank will eventually
deteriorate making engine-starting difficult.
When draining fuel from the fuel tank, use the
hand pomp and set it into the refilling port.
(See Fig. 6-q)
Remove the drain screw of the carburetor.
(See Fig. 6-w)
q DRAIN SCREW
Change engine oil.
Check for loose bolts and screws, tighten
them if necessary.
Clean generator thoroughly with oiled cloth.
Spray with preservative if available. NEVER
USE WATER TO CLEAN GENERATOR !
Pull starter handle until resistance is felt,
leaving handle in that position.
Store generator in a well ventilated, low
humidity area.
1. ENGINE OIL CHANGE (See Fig.
55
-
qq
)
Change engine oil every 50 hours.
(For new engine, change oil after 20 hours.)
(a) Drain oil by removing the drain plug and the oil
filler cap while the engine is warm.
q OIL DRAIN PLUG
(b)
Reinstall the drain plug and fill the engine with oil
until it reaches the upper level on the oil filler cap.
Use fresh and high quality lubricating oil to the
specified level as directed on page 6.
If contaminated or deteriorated oil is used or the
quantity of the engine oil is not sufficient, the
engine damage will result and its life will be
greatly shortened.
5. CHECKING CARBON BRUSH
(See Fig.
55
-
tt
)
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 (0.2 in.) long or less, replace it
with a new one.
