Service History for a Used Machine: What to Ask

Ask the seller for the dated service reports, the engineer's company name, the counter readings at each visit and a list of parts replaced. A machine with a clear, continuous service history is worth more than the same model with none, and a seller who cannot or will not show one is telling you something.

Why does service history matter more than age?

Two machines of the same year can be very different. One has been serviced on schedule by the manufacturer's engineers; the other has been run until it failed and patched by whoever was available. You cannot tell them apart from the outside.

Our machine pages show that support differs by brand. Candela has UK and Ireland engineers, with service contracts recommended. The Lumenis M22 page notes service via the UK and strong third-party availability. The Ultraformer III page says support is distributor-dependent. Because support differs, the service record is how you find out who has looked after the unit, and whether you can continue that arrangement.

What service paperwork should you request?

1. Every service report, in date order
2. The name of the servicing company and the engineer, where listed
3. The counter readings (pulses, shots, hours) recorded at each visit
4. A parts-replaced list with part numbers where possible
5. Any calibration or output test results
6. Invoices for repairs, which are often more honest than the summary report
7. The current service contract, if one exists, and what it covers

Photographs are fine as a first step, but keep copies. If the seller says reports were lost, ask whether the servicing company can reissue them.

What questions should you ask the seller?

Service and maintenance

1. When was it last serviced, and by whom?
2. Was that the manufacturer, the distributor or an independent engineer?
3. How often was it serviced in the time you owned it?
4. Is there a gap of a year or more with no record?
5. Is a service contract in place, and can it be transferred?

Faults and repairs

1. Has it ever been out of action for more than a week?
2. What failed, what was replaced and what did it cost?
3. Were any handpieces, applicators or cartridges swapped, repaired or exchanged?
4. Has it ever been moved between sites, and how?

Use and counters

1. What are the current counters, and what were they at the last service?
2. Was it used daily, weekly or occasionally?
3. Has the lifed part been replaced, and when?

Ownership and support

1. Did you buy it new, and from whom?
2. Is any finance or lease outstanding?
3. Why are you selling?

For the lifed part in question 12, check the model's page. Our HydraFacial MD Elite page explains that consumable tips and serums are bought through the brand, while the Soprano page identifies the handpiece as the lifed part and says an exchange programme exists. A good answer names the part and the date.

What does a good service history look like?

• Dated reports from a named engineer at regular intervals
• Counters that rise steadily between visits
• Replaced parts listed with dates
• Honest account of faults and downtime
• A willingness to let you call the engineer

Which seller answers should make you pause?

None of these is proof of a problem, but each is a reason to ask more questions. Our inspection checklist shows how to test the unit itself once the paperwork looks sound.

How do you check the history with the engineer?

If the report names a service company, ring them. Ask whether the details match, whether the machine was ever flagged for a safety or output issue, and whether they would service it for you. Candela's maintenance guide says clinics should have devices calibrated and aligned and energy output checked before and after use (Candela), so ask whether output tests were ever recorded.

For new owners, a quote from the manufacturer or distributor for a full service is also a pricing tool. If the quote is large, you can reduce your offer by that amount, within reason.

Does the warranty transfer with the machine?

Service history and warranty are related. Our BTL pages say manufacturer warranty transfers only with BTL's agreement, and the EmFace page says to confirm transferability before any private purchase. On a dealer sale, the Stellar M22 page describes around 12 months as typical, and says to verify remaining manufacturer cover on a private sale. Ask for warranty status in writing, not as a verbal promise.

What if you are selling?

Put the service file in order before you list. Our guide on how to sell a used aesthetic machine lists the other documents buyers will ask for. You can then list your machine free with no commission and say in the advert that the full history is available. Our laser hair removal category shows how buyers compare models.

Frequently asked questions

What service history should a used laser have?

Dated reports from the manufacturer or a named engineer, counter readings at each visit, a parts-replaced list and any output test results. One buying guide asks for logs showing regular cleaning, part replacements and calibrations (MissLJBeauty).

Can I get a service history from the manufacturer?

Often, if you have the serial number and the owner's permission. Ask the distributor what they will release, and whether they record work done by third parties.

Is a machine with no service history a bad buy?

Not automatically, but it carries more risk. Price in a full service from an engineer, and inspect it carefully before buying.

Should I ask for a service contract to be transferred?

Yes, if one exists. Ask the provider whether it can be assigned to you and on what terms.

How often should a clinic laser be serviced and checked?

We could not verify a single interval, so ask the manufacturer for its schedule. Candela advises contacting the device maker for specific maintenance guidelines and checking energy output before and after use (Candela).

Does servicing guarantee the output is correct?

No. Field engineers typically calibrate the device, but Ophir suggests this may not give enough regular information and recommends external measurement against the displayed settings (Ophir). Ask whether an output test was recorded.

What does a high pulse count tell me?

That the laser has been heavily used. Compare the count with the manufacturer's recommendations, because some parts wear out much sooner than others (MissLJBeauty).

Prices vary by unit, so get written quotes and let an engineer inspect before you pay.
