IDENTIFCCATION PLATE AND PRODUCT
1 . Injection pump adjustment and repair should be
made by the nearest ZEXEL CORPORATION or
ROBERT BOSCH Authorized Service Outlet.
2. When you ask such authorized service outlet the
adjustment or repair, the identification Plate and
Product Serial Number will give them a necessary
clue to get technical data distributed by the manu-
facturers previously.
Without this data, the Service Outlet will be unable
to effectively service your injection pump.
If you are unable to locate the data applicable to
your injection pump, please contact ISUZU MO-
TORS LTD through your machine supplier.
3. Do not remove the Identification Plate and Product
Serial Number from the injection pump.
Keep the Identification Plate and Product Serial
Number clean at all times. Do not allow it to rust or
become illegible.
