Instruction Manual
Bench Press with Electric Pump “ECE01115”
4.1 START UP
Connect the machine as described in the previous point.
The maximum pressure that the hydraulic equipment develops is 700 kg/cm
2
.
The machine is provided with an external limiter valve rated on factory at 700 kg/cm
2
.
In the cover of the power pack is located the pressure regulation screw.
Release the lock nut and go tightening or releasing the screw, go checking with the gauge, and once that the wished pressure is reached; tighten the lock nut to avoid
that the vibration may decontrol the system.
5. 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.
Always use the original LARZEP parts to prolong the service life of your hydraulic equipment.
