Note also that the pump should be attached to the supporting
structure after replacing the rubber feet with special anti-
vibration feet, which should be screwed to the pump base and to
the supporting plane.
After taking the pump out of its packing case, you are advised to
make the following checks:
a Ensure that the pump has not suffered any damage during
shipping.
b Check that there are no uncovered or loose parts.
Preliminary Operations
Before starting the pump, fill up with lubricating oil as the pumps are
delivered empty.
NOTE
A tin of oil is included in the packing.
CAUTION!
Oil must be poured into the casing through the special threaded plughole and
NOT through the suction line.
WARNING!
Take out the protective caps on the suction and exhaust flanges before doing
anything else. In the event of an accidental start-up, the air inside the pump
could violently expel the protective caps and harm the operator.
