Instruction Manual
Column Press with Electric Pump “EE03116-CE”
6. MAINTENANCE.
The hydraulic circuit of the press is closed, so in normal conditions no oil leakage should be coming up.
In case of oil leakage, after the proper repairing work, you should fill up the tank with hydraulic oil by
LARZEP (Ref: AZ8902)
. The electric pump is equipped
with an oil level indicator to control the need quantity of oil.
As far as a non-continuous use of the press is concerned (1 hour per day), oil replacement should be done once a year. To empty the tank, you should remove the
cover and take the oil out to another container. Please, bear in mind the existing rules for water processing when handling the used oil.
Keep greasy and lubricated the pin bearings, the piston and in general all the parts that might be in friction.
