FIGURE 7. SEQUENCE OF OPERATION
OUT-OF-SERVICE PROTECTION
Protect a generator set that will be out of service for
more than 30 days from damage caused by rust or
corrosion. Use the following procedure to properly
protect the set.
1. Run the generator set with at least a 50 percent
load until thoroughly warm (usually about 1
hour).
2. Turn off fuel supply and allow the engine to run
out of fuel. Also operate the choke manually as
the engine stops to help drain the carburetor
completely.
3. Drain the oil from oil base while engine is still
warm. Replace the oil filter if so equipped.
Replace drain plug and refill. Attach a warning tag
stating type and viscosity of oil used.
4. Remove spark plugs. Pour 1 ounce of rust in¬
hibitor oil (orSAE#10) into each cylinder. (Spray
cans work well for this application.) Turn engine
over by hand at least 2 complete revolutions.
Replace the spark plugs.
5. Replace the air cleaner at least on an annual
basis.
6. Plug the exhaust outlet to prevent entrance of
moisture, dirt, bugs, etc.
7. Clean and oil all exposed engine parts including
carburetor and governor linkage.
8. Wipe generator brushes, slip rings, housing, etc.
Do not apply any lubricant or preservative.
9. Remove the battery and store in a cool dry place.
Coat the battery terminals and cable connections
with vasoline or grease to prevent any corrosion.
Recharge the battery at least monthly or maintain
with a trickle type battery charger.
10. P r ovide a suitable cover if the unit is exposed to
the elements.
RETURNING THE UNIT TO SERVICE
1. Remove the cover and all protective wrapping.
Wipe the oil film off all exposed engine parts.
Remove the plug from the exhaust outlet.
2. Visually inspect the unit for any damage. Checkto
be sure the carburetor and governor linkage are
free. Remove the generator end bell band and
check to be sure the brushes work freely in their
holders.
3. Check the tag to ensure oil of the proper brand
and grade has been installed. Check the oil level.
4. Install the battery (be sure battery is fully charg¬
ed), observing proper polarity. Ground is
negative.
