PREPARATION FOR STORAGE
The following procedures should be followed prior to
storage of your generator for periods of 6 months or longer.
1. Drain fuel from fuel tank and strainer (cup) carefully by
disconnecting the fuel line. Gasoline left in the fuel tank
will eventually deteriorate making engine-starting
difficult.
2. In order to remove the fuel in the carburetor, run the
engine at no-load until it stops.
3. Disconnect the terminal of the battery.
4. Change engine oil.
5. Check for loose bolts and screws, tighten them if
necessary.
6. Clean generator thoroughly with oiled cloth. Spray with
preservative if available.
NEVER USE WATER TO CLEAN GENERATOR!
7. Store generator in a well ventilated, low humidity area.
SERVICE AND REPAIRS
All quality generators will eventually require servicing or replacement of parts because of wear from
normal use. To assure that only authorized replacement parts will be used, all service and repairs
must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY.
TROUBLESHOOTING
When generator engine fails to start after several attempts, or if no electricity is available at the
output receptacles, check the possible causes in accordance with the following table. If your
generator still fails to start or generate electricity, contact your nearest HITACHI dealer or authorized
service center for further information or corrective procedures.
