Hydraulic Press Repair / Breakdown / Servicing & Support

JPS Machinery boast the Largest Dealer Service Team in the UK and can cater for all new & used hydraulic press machinery through our in house service team.


Typical Repair Breakdown Faults:

Leaking hydraulic cylinders requiring the seals replacing
Low hydraulic pressure often caused by over heating
Hydraulic oil temperature should not exceed 150 degrees Fahrenheit Hydraulic filters in need of cleaning or changing
Replace the air cooled heat exchangers filter

Slow pressure build up,i.e more than 2 seconds – check relief valve is working

Faulty Hydraulic pump motor the motor nipple has not been used as recommended by the motor manufacturer

Oil leaks – Tighten or replace leaking hoses or fitting

Electrical faults such as sticking contactors, faulty solenoids


Typical Service Requirements

At the beginning of the work shift, inspect the Fiber laser cutting machine a visual inspection of all areas will allow you to notice and address small issues before they become significant problems

It is important to understand the function, design, and operation of your Hydraulic Presses

The operators role in service / maintenance of a hydraulic press is a major part of keeping the equipment running efficiently. It is important to immediately investigate strange noises, vibrations, or something that doesn’t look right. The quicker problems are detected and corrected, can often mean a less expensive fix.

 it’s the small preventive measures that keep a hydraulic press up and running.


A daily maintenance check list should include the following: 

Clean Hydraulic oil is the key to a healthy hydraulic system. Dirt particles may enter the hydraulic tank. Keeping the oil clean and filling the reservoir to capacity are critical, re filter the oil every 6 months using a 10/15 micron filter, completely replace the oil around 2/3000 hours of actual use

But clean the tank and replace the suction filters before replacing the hydraulic oil

Check the ram A press’s hydraulic piston rod should be moist but not dripping oil

Bronze bushings should be greased as necessary.

Check for oil leaks on all hydraulic lines

Check for loose bolts around the tooling area.

Check the connection between the hydraulic cylinders & the press brake beam

Check the oil temperature

Check light curtains to do this is to break the beam while the ram is traveling down. The press should stop immediately. Breaking the beam on the upstroke might not stop the press. Refer to the owner’s manual for proper function.

Electrical Systems:

Emergency stop buttons, check the dual circuits relays, check the safety relay, look for welding of contactors

Check all terminal strip connections , relays, terminal boxes on motors.

Reseat all printed circuit boards and check for physical damage (cracked solder points, burned parts, etc.).

Check all voltages coming from power supplies and transformers.

Check all external cables and switches fittings for damage

Check control panel cooling fans are operational.

Clean control cabinet to remove dust particles
