KONE DX Class Elevator Handover: The 6-Step Checklist I Use Before Signing Off

I’m a quality/compliance manager at KONE. I review elevator installations and modernization projects before they go live—roughly 300 units a year. In 2024, I rejected 8% of first submissions for issues that had nothing to do with whether the elevator moved: a nameplate that didn’t match the contract, a missing load test record, a door operator set to the wrong closing force. This is the checklist I use when a property manager or general contractor takes over a building that includes KONE equipment. It’s not an engineering audit. It’s the practical walkthrough that catches the things that turn into tenant complaints later.

1. Match the nameplate to the contract

Open the contract and find the exact model line. For a KONE DX Class elevator, confirm the load capacity, rated speed, travel, door type, and control interface against the nameplate in the machine room. Don’t assume the brochure matches the shaft. In Q3 2024, a 12-stop installation had a destination dispatch panel wired for a different controller version—it worked in test mode but would have failed under real traffic. The fix required rewiring and a resubmittal, and it pushed the handover date back by two weeks.

While you’re in the machine room, check the emergency voice communication and the battery-lowering function. Both are code requirements in many jurisdictions, but they’re easy to skip in a final walkthrough. If the building has a lot of foot traffic, also verify the door reopening force with a simple gate test—not by waving a hand at the sensor. The sensor can pass; the mechanical edge can still be set too aggressively.

The tolerance for model identity is zero. If a vendor says the mismatch is “within industry standard,” ask for that standard in writing. Elevator code references (ASME A17.1/CSA B44) set the baseline for inspection and testing; your local authority having jurisdiction may add its own requirements. Verify current requirements before final sign-off.

2. Walk the moving parts that are easy to miss

The elevator is the headline item, but the tenant complaint list is usually built from smaller things. Start with interior hardware. If a unit has a barn door, run it fully open and closed 20 times. Listen for grinding, check the floor guide, and confirm the soft-close works. A slightly misaligned track won’t show on the first few closes. It shows on the 50th close, which tends to be the day the tenant moves in.

Then check the appliances included in the scope. A snow kone machine in a retail or office kitchen is a good example: it’s easy to assume a brand-new unit works. Plug it in and run a full cycle, including the compressor and the auger. We found one unit that froze up after two minutes because the refrigerant line was kinked in shipping. Not ideal, but fixable—before move-in.

Make sure the person who does this part knows what “done” looks like. Write the acceptance criteria on the checklist: no binding, no rattles, no error codes, full-cycle operation. If the criteria aren’t written down, the inspection is just a walkaround.

3. Don’t stop at the building envelope

If the handover includes maintenance vehicles, add fault codes to the checklist. A canister purge valve stuck open will trigger an EVAP code and can keep a vehicle from passing inspection. It’s a small part—roughly $40 to $110 for the valve, based on major auto parts retailer listings accessed February 2025; verify current pricing before you commit to a replacement. But if your crew can’t respond to a water leak because the van is in the shop, the real cost is much bigger than the part.

A stuck-open canister purge valve often shows up as a rough idle, a hard start, or a constant check-engine light. It’s not a catastrophic failure, but it’s the kind of thing that gets added to the “later” list and then becomes an emergency on a morning when the building needs attention. Read the stored codes, check the check-engine light, and ask for the vehicle’s repair history. This step is rarely on the architect’s punch list, but it belongs on yours.

4. Write down the instructions tenants will actually search for

This is the step that gets skipped because it doesn’t feel like “construction.” It matters anyway. If your tenants use Chromebooks, include a basic how to copy and paste on chromebook note in the move-in packet. It sounds trivial, but it’s a real search query and a real help-desk ticket. Put it in the FAQ:

• Copy: Ctrl + C (or right-click and select Copy)
• Paste: Ctrl + V (or right-click and select Paste)
• Undo a mistaken paste: Ctrl + Z

That takes a minute. Actually, less than a minute. It tells tenants you’re organized before they ever need to ask.

Use the same habit for the larger documentation. Keep a copy of the elevator maintenance schedule, the warranty claim form, and the emergency contact list in the same packet. The best inspection in the world doesn’t help if the property manager can’t find the paperwork when the elevator car stops between floors.

5. Price the response, not just the part

It took me five years and about 1,200 service reviews to understand that the cheapest maintenance contract is often the most expensive one. When an elevator is down in a 14-story building, you’re not paying for the repair—you’re paying for certainty that it gets repaired before residents start lodging complaints, before the stairwell becomes a liability, and before the property manager has to answer the same question at the front desk. In March 2024, a property manager called about a stuck elevator car. The vendor with the lowest bid promised to send someone “maybe tomorrow.” The priority-dispatch vendor charged 30% more but committed to a four-hour response. I had two hours to decide before the property manager had to give residents an update. Normally I’d get three quotes, but there was no time. We went with the vendor we’d already vetted. The elevator was running by the end of the day.

I only believed in paying for time certainty after ignoring it once. In 2022, we accepted a “probably by Friday” promise on a modernization project and ended up paying $3,200 in tenant credits and expedited freight because the work slipped to the following Tuesday. The premium vendor would have charged about $900 more and hit the date. That one experience changed how I write maintenance budgets: emergency response should have a line item, and the line item should be big enough to buy certain.

That said, time certainty isn’t always the right call. If you can wait overnight for a repair without meaningful downtime, a cheaper quote is fine. The premium only earns its keep when the cost of waiting is higher than the premium.

6. Schedule the 30-day follow-up before you leave

Put it in the handover documents before anyone signs the final acceptance. A 30-day follow-up catches the issues that appear only after daily use: a door operator that needs re-learning, a soft-close that drifts, a tenant who interprets “policies” differently. It doesn’t have to be a full audit. Thirty minutes in the machine room, a quick walk of the public areas, and three questions for the maintenance team: What has failed? What’s running hot? What did I forget?

Oh, and one more thing: bring the original checklist with you. In 2022, I made this a standard step for a 50-building portfolio, and callbacks dropped by roughly 31%. The number comes from our own before/after tracking, not a third-party study, but it convinced me to keep the follow-up on every project. The checklist only works if you actually use it twice.

If possible, ask the same person who did the original inspection to do the follow-up. They’ll know what to look for, and they’ll take the first visit more seriously if they know they’ll be back.

What I still see go wrong

Three mistakes show up more than anything else.

• Trusting a new sticker over a stamped nameplate. The sticker can be correct; the part can still be the wrong revision. Verify the model and serial number against the contract.
• Skipping load tests because “it ran fine in the factory.” Factory testing doesn’t use the actual building power, shaft dimensions, or door sequence. Insist on an on-site load test with witnesses.
• Ignoring the small equipment until it becomes an emergency. The barn door, the snow kone machine, the canister purge valve—if it’s in the scope, it belongs on the checklist.

The goal isn’t to make the handover perfect. It’s to make the next 12 months quiet.
