FAAC Gate Operator Repair — Hydraulic Service

What this video shows
FAAC builds hydraulic gate operators, which need different diagnostics and different parts to a chain drive. This shows the repair being carried out: pressure checked, seals addressed and the operator returned to normal travel speed.
The fault
- The gate had been getting progressively slower over about eighteen months. By the time we were called it was opening roughly two-thirds of the way and stopping, and the owner had been told twice that the operator was finished and needed replacing with a different brand.
How it was diagnosed
- Fluid level was low and the fluid itself was well past its service life. Operating pressure tested well below the manufacturer figure.
- The ram seals had been weeping long enough to leave a residue trail down the housing — visible once the cover came off, and the reason the level had dropped.
- Nothing was wrong with the motor, the board or the gate itself. The gate moved freely by hand through its full travel.
The fix
- Replaced the seal kit, flushed and refilled with correct-specification fluid, and reset operating pressure to manufacturer figures.
- Ran the gate through a full cycle sequence and re-checked pressure warm, since hydraulic behaviour changes as fluid comes up to temperature.
A FAAC that has become slow is almost always reporting hydraulic pressure, not a dying motor. The reason it gets quoted for replacement so often is that most technicians do not service hydraulics — which is a statement about the company, not about the gate.
