Instruction Manual
Column Press with Electric Pump “EE03116”
SUBSTITUTION OF THE TRANSPORT PLUG
Replace the plug of transport located in the cover of the tank, by the pressurized plug given with the press. (Plastic bag in the lever of the distributing valve).
INSTALLING THE GAUGE
1-Replace the threaded tap in the top of the cylinder by the gauge (supplied separately).
2-Tighten the gauge cone to the gauge adaptor seat by using a flan wrench size 22.
3-Hold the gauge screen by hand during threading process and after reaching a comfortable reading position set the gauge screen free so that it turns the last quarter
solidarily with the thread.
4- The hydraulic system also includes a gauge adaptor with 3/8 “BSP thread.
CHECKING THE RIGHT OPERATION OF ALL DEVICES AND MECHANISM
1.
Put the distributor valve’s command in position “C” and push the start switch button (black) of the electrical cabinet.
2.
Check the rotate of the motor.
3.
If the rotate sense is the opposite of the labelled arrow in the motor, change the phases of the electrical connection. Disconnect the equipment for this
operation.
4.
Put the distributor valve’s command ion “A” position. The cylinder’s piston advances, familiarize with the speed.
5.
Guide the piston to the end of the stroke and submit to pressure, check the reading of the gauge and that there is not oil leaks.
6.
Put the distributor valve’s command in “C” position to assure that the cylinder maintains the pressure.
7.
Put the distributor valve’s command in “B” position to return the piston, familiarize with the speed.
8.
Push the stop switch (red) of the electrical cabinet, to stop the motor. Move the command from “A” position to “B” position to depressurize the cylinder
and finally let the distributor valve’s command in “C” position.
5. START UP.
Connect the machine as explained in the previous point.
Displacement of the table’s height:
MODEL EE03116
Choose the wished height.
Elevate or descend manually in alternative way (from one column to the other) and from one hole to other hole.
Be cautious in this operation to avoid the fall of the table.
VERY IMPORTANT! THE POSITIONING SYSTEM OF TEH TABLE IS NOT DESIGNED TO RESIST THE FORCE THAT THE CYLINDER IS
ABLE TO DO. THE USE IS ONLY IN ORDER TO POSITIONING THE TABLE.
Regulation of the maximum working pressure:
The maximum pressure developed by the hydraulic system is 700 Kg/cm
²
. An internal limiter valve races in the moment that the installation reaches the pressure.
If the working pressure wished is inferior, act in the following sense:
1.
In the cover of the power pack is located the pressure regulation screw.
2.
Release the lock nut and go releasing the regulation screw. Go checking with the gauge and once the pressure wished is reached, tighten the lock nut to
avoid that the vibrations deregulate the system.
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. AZ8901
); 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 LARZEP 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
LARZEP
parts to prolong the service life of your hydraulic equipment.
