5.0 COMMISSIONING AND STARTING
This section describes the operations to be followed on commissioning along with
some advice for starting the machine for the first time.
5.1 FILLING THE PRESS WITH OIL
To fill the press, use exclusively the oils indicated in the table or ones of equivalent
reliability. The choice must be made considering the environmental conditions and
the operating features of the press.
Choose the type of oil (column A, B, C) on the basis of the average working
temperature, for temperate climates the reference column in “B”. For operating
conditions in colder climates user column “A”, for warmer climates select column “C”.
5.2 FIRST STARTING
The press was shipped without oil.
After you have filled up the tank you have to stroke the hand pump until the ram is
fully extended out of the cylinder, release the wheel under the pump to return the
ram. You have to verify the oil level in the tank and if needed refill the tank. You
have to repeat the above-mentioned operation sometimes to bleed the air from the
system. See Air Discharge Section 5.3.
The level of oil in the tank may fall on starting, because of:
- absorption of volume by the cylinder
- absorption of volume by the pumping unit
- discharge of air bubbles remaining in the piping
It is necessary to top off the level of oil bringing it up to the correct height.
