Surgery two of a three-chair practice that consolidated. Upholstery sound; one hydraulic seal weeps under full load and was never repaired.

Condition report

Grade B at 71% confidence

Grade B. Sound, working.
Confidence in this grade
x

Confidence is how much evidence the grade rests on — photo coverage, invoice coverage and whether running hours were verified. It is not how good the unit is.

Age basis
Serial block 2019-DL read from the base plate, corroborated by an installation invoice dated 10 Apr 2019.

Known faults

  • One hydraulic lift seal weeps under full load. Quoted at $410 fitted in Feb 2024 and not repaired. Budget the seal kit before the chair takes patients.
  • Upholstery is sun-faded on the headrest side. Sound and unsplit, but it will not match a new headrest.
  • Cuspidor bowl carries limescale staining that did not lift with a descale.
  • No handpieces, no scaler and no compressor included — the delivery arm tubings are bare.

Known faults cannot be left blank on this platform. A seller with nothing to declare has to type it.

Documents read

Uploaded by the seller and put through extraction. An invoice that could not be read is recorded as a failure, not silently dropped — and it lowers the confidence figure.

What we don’t know

Everything above is evidenced. This is what the report does not cover, named in full. The panel is on every listing and cannot be collapsed away.

  1. 01

    Three of the eight required angles are missing

    No photograph of the rear service connections, the underside of the base, or the accessories as a set.

  2. 02

    No service invoice for 2020, 2022, 2023 or 2025

    The chair is seven years old and three service records are on file. Four of those years are undocumented, so the maintenance history is not continuous.

  3. 03

    Waterline and suction condition unverified

    The unit was not connected to water, air or drainage. Biofilm load in the waterlines, suction motor condition and amalgam separator state are all unassessed.

  4. 04

    The unit was not powered or pressurised

    The lift was not cycled under load, so the severity of the known hydraulic weep is recorded from the 2024 service note, not from a current test.

From the seller

Surgery two of a three-surgery practice in Leeds city centre that consolidated onto two rooms in June. The chair was installed new in 2019 and used four days a week. It is being sold because the room is being turned into a decontamination suite, not because the chair failed. The known hydraulic weep is priced in: the seal kit was quoted at $410 fitted in Feb 2024 and the practice chose not to authorise it.

Known faults are declared in the condition report above, not in this description — 4 entries.

Included with the unit

  • Foot control and cable
  • Headrest and articulating arm
  • 4 × handpiece tubings
  • A-dec 300 LED operating light on chair-mount post

  • Water supply and suction to drain — isolate and drain before removal
Collection windowWeekdays 08:00–13:00 by appointment, until 31 October 2026
