the oil supply felt
Broken oil pack
NOTE 1: Expected occurrence ratio
Oil supply units enclosed with new machines and in maintenance kit G (Oil Supply Unit) have been
inspected. Any oil supply units, which exhibited oil leakage, were replaced.
Therefore, it is expected that the occurrence ratio in the field is very limited.
NOTE 2: How to read the lot number of the oil supply unit
Example: Z1830J
(Z): Vendor code, (1): Year, (8): Month, (30) Day, (J): Suffix
NOTE 3: Oil pack breakage
To prevent excessive oil from soaking through the oil supply felt, a special jig has been used to assemble the
oil pack in the unit and the oil amount has been optimized.
1. The condition of the oil supply felt with the shield tape
and units without a problem have been selected.
(See NOTE 1.)
2. The oil cartridge vendor has been instructed how to set
the oil pack in the unit.
3. A special jig has been used to assemble the oil pack in
the unit and oil amount has been optimized.
(See NOTE 3.)
