HIGH
ALTITUDE
For operation at altitudes of 2500 feet or more, close
the carburetor main jet adjustment slightly to main-
tain proper air-to-fuel ratio. Referto the Fuel System
section.
Maximum power will be reduced about 4
percent for each 1000 feet increase in altitude.
PROTECTION
FOR
EXTENDED
OUT-OF-
SERVICE
PERIOD
Protect an engine that is to beout-of-service for more
than 30 days as follows:
1.
Run engine until thoroughly warmed up.
2.
Turn off fuel supply and run until engine stops
from lack of
fuel.
3. Drain oil from oil base while still warm. Attach a
warning tag to refill before operation.
4.
Remove each spark plug. Pour one ounce (two
tablespoons) of rust inhibitor (orSAE#50) oil into
cylinder. Crank engine over a few times to
distribute oil film on cylinder walls and rings.
Reinstall each spark plug.
5. Service air cleaner per maintenance schedule.
6. Lubricate governor linkage. Protect against dust,
etc. by wrapping with a clean cloth.
7. Plug exhaust outlet to prevent entrance of bugs,
moisture, or dirt.
8. Wipe entire unit clean. Coat parts likely to rust
with a light film of grease or oil.
9. Provide a suitable cover for entire unit.
10.
Disconnect battery and follow standard battery
storage procedure.
CAUTION ) Discharged batteries are subject to severe
damage if exposed to freezing temperatures.
Store all batteries in a fully charged condition and maintain charge
during storage.
RETURNING
THE SET TO
OPERATION
1.
CHECK SERVICE IDENTIFICATION TAGS to
properly service the engine.
2.
Uncover and remove all storage seals from
engine. Remove any dust, dirt, or foreign matter.
3. CHECK fuel supply tanks for moisture ac-
cumulations (drain tanks if necessary). CHECK
lubricating oil for moisture or contamination
(drain if necessary). CHECK fuel line connec-
tions,
all wiring connections, and exhaust line
connections.
4.
Service air cleaner. Bleed fuel system (if moisture
or contamination are found in
fuel,
replace filters
and clean fuel pump sediment bowl).
5. Check tag on oil base and verify that oil viscosity
is still correct for existing ambient temperature.
6. Clean and check battery. Measure specific gravity
(1.260 at 25° C [77° F]) and verify level to be at
split
ring.
If specific gravity is low, charge until
correct value is obtained. If level is low, add
distilled water and charge until specific gravity is
correct.DO NOT OVERCHARGE..
"WARNING k
Do smoke
while servicing batteries.
Explosive gases are emitted from
batteries in operation. Ignition of these gases can cause
severe personal injury.
7. Check engine forfuel oroil leaks. Correct leakage
as required.
8. Install fully charged batteries.
9. Start engine and check while running for leaks,
correct voltage output, and proper cooling.
After engine has started, excessive blue smoke will be exhausted
and the engine will run rough until the rust inhibitor or oil has
burned away.
