servicing the equipment. Use tools with insulated handles.
Remove the negative (--) lead first when disconnecting the
battery. Reconnect the negative (--) lead last when
reconnecting the battery. Never connect the negative (--)
battery cable to the positive (+) connection terminal of the
starter solenoid. Do not test the battery condition by shorting
the terminals together.
3.9 Belt Check
Check the belt tension at the intervals specified in the
service schedule. If the tension is not within
specification, adjust as necessary using the following

3.10 Storage Procedure
Follow the procedure below when storing your
generator set for a long period (3 months or more).
1. Start and run the generator set until it reaches
operating temperature or about 15 minutes.
2. Stop the generator set.
3. Change the oil and oil filter; see Section 3.3.5, Oil
and Filter Change.
4. Drain the fuel completely from the fuel tank to
prevent accumulated moisture from mixing with the
fuel.
5. Check the engine coolant protection; see
Section 3.6.
Note: Use antifreeze capable of withstanding the
lowest possible temperatures.
6. Keep spark plugs in their holes or seal spark plug
holes with suitable threaded metal plugs.
7. Clean the exterior of the generator set and spread a
light film of oil or silicon spray over any exposed
surfaces that may be subject to rust or corrosion.
8. Seal the air inlet, exhaust pipe, and fuel tank cap
with tape.
9. Disconnect and remove the battery. Place the
battery in a warm, dry location for the storage
period. Recharge the battery once a month to
maintain a full charge.
10. Select a well-ventilated (not humid or dusty)
location to store the generator.
11. Cover the entire unit with a dust cover.
