How to open a FAAC 400 / 422 / S450 by hand
Open a FAAC 400, 422 or S450 hydraulic swing gate by hand. Guidance from our family-run team in Chafford Hundred.
Safety checks for the 400 / 422 / S450
Gate type: swing (hydraulic). Steps below follow the manufacturer manual as drafted by our Tech Support team.
Safety first
- Isolate the power at the gate isolator or fused spur before you touch the release, and again before you lock it. If a backup battery is fitted the gate can still move with the mains off — do not release it; call us.
- Find the release key (and any extra locks such as drop bolts or magnetic locks) before you start. Do not force a lock or use pliers.
- Do not attempt this if the gate is damaged, leaning, off its hinges or track, has no travel stops, or sits on a steep slope you cannot control.
- Keep children, pets and others clear of the gate path, hinges and the gap at the end. Move the gate slowly by hand.
- Never open a motor cover, control box or wiring. This guide is for gates only — barriers are engineer-only.
- If you are unsure at any point, stop and call our family-run team on 01375 886299.
You'll need
- The FAAC release key supplied with the gate
- A second person if the gate is heavy or on a slope
Safety first
Warning: A released gate can swing or roll on its own on a slope or in wind, and it can trap fingers, children, pets or cars. - Only release the motor when the gate has completely stopped. - Switch the power off at the isolator (the fused spur or switch for the gate) before you release it and before you lock it again. - If your gate has a back-up battery, it can still move with the mains off. Do not release it: call us. - Move the gate slowly by hand and keep everyone clear of hinges, posts and the gap at the end. - Never open the motor cover or control box, and never touch the wiring. - This guide is for gates only. It does not apply to car park barriers: barrier releases are engineer-only, so call us.
Release the motor
- Make sure the gate has stopped and switch it off at the isolator. FAAC say cut the power before releasing and before re-engaging.
- Lift the protective plug and fit the key.
- Turn the key a quarter turn (90 degrees) clockwise to open the cover, then lift the cover up.
- Turn the release knob anticlockwise about two turns.
- Open or close the gate by hand.
Put it back to automatic
FAAC's release sheet does not give steps for locking this model back to automatic. Leave the gate released and secure it by hand if you can, then call us and an engineer will re-engage it.
Still not working?
- Key will not turn, or you do not have the key: do not force it or use pliers. Call us and we will book an engineer.
- Gate will not move by hand after releasing: something may be jammed, or a hinge, wheel or track may be damaged. Stop, leave it, and call us.
- Gate moves on its own, sags, or hangs off a hinge: keep everyone away and call us straight away.
- Gate does not work on the remote after you lock it and the power is back: the gate may need to re-learn its travel. Call us; do not press buttons on the control board.
