Before You Place The Generator In Long-Term Storage; Returning The Engine To Service - Yanmar YDG Series Operation Manual

LONG-TERM STORAGE
BEFORE YOU PLACE THE
GENERATOR IN LONG-TERM
STORAGE
1. Perform the next periodic maintenance
procedure. For example, if there are 10 hours
remaining before the 200 hour maintenance,
you should do the maintenance before you
place the engine in storage. See Periodic
Maintenance Schedule on page 47.
2. Start the engine. Allow the engine to run
without load for approximately five minutes and
then stop the engine.
3. Drain the engine oil while the engine is still
warm and fill with new oil. See Replace engine
oil on page 51.
4. Push the decompression lever down and hold it
while slowly pulling the recoil starter two or
three times. Do not start the engine.
5. Pull the decompression lever up. Pull the recoil
starter slowly and stop when there is
resistance. This procedure closes the intake
and exhaust valves in the compression position
and helps prevent rust.
6. Allow the engine to completely cool then drain
the fuel tank or fill it completely.
7. Protect the air cleaner, muffler and electrical
components (dynamo, starter motor, switches)
from water and dust.
8. Disconnect the negative (-) battery cable to
prevent the battery from discharging.
9. Check the battery fluid and add distilled water
as required. See Check Battery Electrolyte
Level on page 34.
10. Charge the battery once a month during
storage. See Charging the Battery on page 25.
11. Clean the generator and store it in a dry place.
Always protect the air cleaner and electric
components from damage when you use steam
or high pressure water to clean the generator.
12. Rotate the engine without starting, every four to
six months.

RETURNING THE ENGINE TO
SERVICE
1. Perform the Daily Checks on page 34.
2. Start the engine. Allow the engine to run
without load for approximately 5 to 10 minutes
while you check for:
• abnormal noises or vibration
• fuel and engine oil leaks
Avoid personal injury. Always wear eye
protection when checking for fuel leaks and
never check for a fuel leak with your hands.
Always use a piece of wood or cardboard.
Have your authorized YANMAR dealer or
distributor repair the damage.
3. Avoid prolonged operation at maximum load for
the remainder of the first hour of operation.
