Using suitable filtration when filling the system and replacing hydraulic oil according to the equipment manufacturer’s recommendations can help reduce wear and avoid costly repairs.

How Our Hydraulic Repair Service Works

We follow a clear repair process so that you understand what is happening with your equipment and what the repair will involve.

1. Submit a Repair Request

Contact us by phone, Viber or Telegram:

+38 068 277 99 23

Describe the equipment, its model and the symptoms. If possible, send:

• A photo of the equipment nameplate

• Photos of the hydraulic unit and connections

• A short video showing the problem

• Information about the operating voltage and pressure

2. Preliminary Assessment

Based on the information provided, we will assess the possible causes and explain what diagnostics may be required.

Where possible, we will provide an initial estimate of the repair scope.

3. Equipment Diagnostics

Diagnostics can be carried out in our workshop in Kharkiv or through an on-site visit by prior arrangement.

We inspect the equipment and identify the cause of the malfunction.

4. Repair Estimate and Approval

Before starting the repair, we prepare an estimate outlining the proposed work and the expected cost.

No repair work is carried out without your approval.

5. Professional Repair

We carry out the agreed repair using suitable replacement components and spare parts available to us in Ukraine.

6. Testing Under Operating Conditions

After the repair, we check the equipment’s operation and, where applicable, test it under working pressure.

Our goal is to return equipment that has been checked and tested, not simply switched on for a brief demonstration.

7. Warranty

We provide a 2-month warranty on completed repair work and installed replacement parts, subject to the agreed warranty conditions.

Frequently Asked Questions About Hydraulic Equipment Repair

Do you repair hydraulic equipment that was not purchased from CraftOil?

Yes. We consider repair requests for hydraulic presses, power units, cylinders and other hydraulic equipment from different manufacturers, including imported models.

Send us the model information, photos and a description of the problem so we can assess whether we can help.

How long does hydraulic equipment repair take?

Repair time depends on the fault, equipment condition and availability of replacement parts.

Common repairs, such as seal replacement, hydraulic hose replacement and solenoid coil replacement, may take several days. More complex repairs are assessed individually.

Do you provide on-site hydraulic equipment repair?

On-site service may be available for stationary or large equipment that cannot be transported economically. This is arranged individually.

How should I prepare hydraulic equipment for shipping?

Preparation depends on the equipment design.

In general, hydraulic oil may need to be drained where appropriate, hydraulic ports should be protected with suitable caps or plugs, moving components should be secured, and the equipment should be packed safely.

Contact us before shipping so we can provide instructions for your specific equipment.

Do you work with customers from Europe?

Yes. We accept enquiries from European customers and can discuss international equipment delivery and repair arrangements individually.

What warranty do you provide on repairs?

CraftOil provides a 2-month warranty on completed repair work and installed replacement parts, subject to the agreed warranty conditions.

What should I do if my hydraulic power unit does not build pressure?

Possible causes include an incorrect motor rotation direction, insufficient hydraulic oil, a pump malfunction, a faulty valve or internal leakage.

On three-phase equipment, an incorrect phase sequence can cause the motor to rotate in the wrong direction. However, electrical checks should be performed safely by a qualified person.

If the problem persists, contact CraftOil for technical consultation.

Can you help without sending the equipment for repair?

Yes. Some issues can be assessed remotely by phone or video. Our initial remote technical consultation is free of charge.

Do you repair hydraulic oil extraction presses?
