Column Press with Electric Pump “WP60EEC”
6. MAINTENANCE, PROBLEMS AND SOLUTION
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 LUKAS hydraulic; the 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 waste
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.
USE ONLY LUKAS HYDRAULIC OIL
Other grades of oils or types of hydraulic fluid (such as brake fluid) may affect the performance of the equipment or cause the deterioration of the seals.
DO NO ATTEMPT TO FILL THE PUMP WITH OIL WHILE IT IS CONNECTED TO A CYLINDER WHICH IS SUSTAINING A LOAD
BECAUSE IT MAY OVERPRESSURIZE THE RESERVOIR WHEN THE PISTON RETRACS AND CAUSE DAMAGE OR INJURY
Always use the original LUKAS parts to prolong the service life of your hydraulic equipment. LUKAS or your authorized dealer can supply you with
original parts for simple maintenance work
