How to Inspect a Machine Remotely: A Buyer's Live Video-Call Checklist

You cannot always fly to China to inspect a machine in person. A live video call is the next best thing — but only if you know what to ask for. Here is the complete checklist for turning a video walkaround into real due diligence: what to prepare, what to look at, what operations to request, and how to spot the common tricks that sellers use to hide problems.

Why a live call beats a recorded video

A recorded video shows you what the seller chose to record. A live video call means you control the camera: you can ask the operator to zoom in on the data plate, point at the hour meter, start the engine from cold, pan slowly across the undercarriage, or hold a phone light into a dark engine compartment. You can ask questions in real time and watch how the operator responds. A seller who is confident in the machine will happily show you everything. A seller who hesitates, deflects, or keeps the camera moving fast is hiding something.

Remote inspection is not a substitute for an in-person or third-party inspection, but it is a powerful tool for filtering out bad machines before you invest in a plane ticket or an inspector. It is also essential for buyers who are purchasing from a distance and need to verify the machine's condition before paying the balance. For the highest-value purchases, combine a remote video inspection with an independent third-party inspection — our inspection service page explains the options.

Before the call, review our guides on how to inspect a used excavator and the 29-point inspection process so you know what good condition looks like. You should also verify machine year and hour readings independently, as hour meter tampering is common.

Before the call: preparation checklist

A productive video inspection starts before the call. Send the seller these requests at least 24 hours in advance:

• Machine documents: Ask the seller to have the data plate (VIN plate), hour meter, service records, and any recent repair invoices ready to show on camera.
• Cold engine: Ask the seller not to start the engine before the call. A cold start reveals problems (smoke, hard starting, unusual noises) that a pre-warmed engine hides. This is the single most important request.
• Clean machine: Ask the seller to wash the machine before the call so you can see the frame, cylinders, and undercarriage clearly. A machine that is deliberately kept dirty may be hiding leaks or damage.
• Good lighting: Schedule the call during daylight hours if the machine is outdoors, or ensure the workshop has bright lighting. Ask the seller to have a flashlight or phone light ready for dark areas.
• Stable connection: Ask the seller to use a device with a good camera and a stable internet connection. A shaky, low-resolution feed is useless for inspection. If possible, use a platform that supports HD video (WhatsApp, WeChat, Zoom).
• Operator present: Ensure a qualified operator is present who can start the engine, operate the controls, and perform the tests you request.
• Recording: Ask the seller for permission to record the call. If they refuse, that itself is a red flag. Record the call for your records and for later review.

The video inspection walkaround

Structure the call in a logical order so you do not miss anything. Here is the sequence to follow:

1. Exterior and structure

Start with a slow 360-degree walkaround, pausing at each corner. Look for frame damage (cracks, welds, bends in the main frame, boom, arm, or bucket — repainted welds can indicate a repaired crack), body panel damage (dents, missing panels, mismatched paint), counterweight damage, and track/tire condition. For tracked machines, check track pad wear and sagging; for wheeled machines, check tread depth, sidewall damage, and whether all tires match. Ask the operator to zoom in on any suspicious areas.

2. Undercarriage

The undercarriage is the most expensive wear component on an excavator — a replacement on a 20-ton machine can cost USD 8,000–15,000. Ask the operator to show the track frame from the side, zoom in on track pins and bushings (check for wear or ovality), show bottom rollers (look for flat spots, seized rollers, leaking seals), and show the sprocket teeth (worn or hooked teeth indicate high hours). If the machine is on blocks, ask to see the underside of the track frame and center joint.

3. Hydraulic system

Hydraulic failures are the most common and expensive repairs. Check each cylinder rod (boom, arm, bucket) for scoring, pitting, chrome damage, or oil residue (leaking seal). Ask the operator to cycle each cylinder fully so you can see the entire rod. Check all hoses for cracks, bulges, seepage, or chafing. Ask to see the main hydraulic pump — look for leaks and listen for whining. Check the control valve block for wetness. If possible, ask the seller to show a small oil sample on a white surface — milky oil indicates water contamination, dark or burnt oil indicates overheating.

4. Engine

This is where the cold-start request pays off. Ask the operator to start the engine cold and watch for: hard starting, smoke (blue = burning oil, black = over-fueling, white = coolant in combustion or unburned fuel — a small amount of white smoke on cold start in cool weather can be normal, but persistent smoke is a red flag). Let it idle 2–3 minutes, listening for knocking or tapping. Then raise to high idle and check for smooth acceleration and smoke under load. Ask to see the engine compartment — turbocharger (oil leaks, shaft play), exhaust manifold (cracks, soot leaks), radiator (damage, coolant leaks), and alternator/belts. Check the coolant for oil (head gasket failure) and the engine oil dipstick for milky oil (coolant contamination).

5. Cab and controls

Zoom in on the hour meter and record the reading — compare it with the machine's age and condition (a 10-year-old machine with 2,000 hours is suspicious). Check the instrument panel for warning lights or error codes. Test the joysticks, pedals, and switches. Turn on the AC and heater to confirm they work (AC failure is common and expensive in hot climates). Check for cracked or missing glass, and inspect the seat and interior — a well-maintained cab often correlates with a well-maintained machine.

6. Operational tests

The operational test is the most revealing part. Ask the operator to perform these specific actions:

• Boom raise / hold: Raise to full height, release, hold 30 seconds. The boom should not drift down more than a few centimeters.
• Arm / bucket cycle: Cycle fully in and out several times — watch for jerking, slow movement, or unusual noises.
• Swing test: Swing fully left and right — listen for grinding from the swing bearing or motor, check for excessive play.
• Travel test: Drive forward, backward, and pivot turn — watch for uneven track movement (one track faster = worn travel motor), listen for final drive noises.
• Load test (if possible): Apply load with a full bucket or by pushing against a solid object — black smoke, stalling, or hydraulic whining indicates problems.
• Blade / stabilizer test (if equipped): Operate fully in and out, check for drift and smooth operation.

Common deception tactics to watch for

Unfortunately, some sellers use tricks to hide machine problems during video inspections. Here are the most common ones and how to counter them:

Tactic	What it hides	How to counter
Pre-warming the engine	Cold-start smoke, hard starting, unusual noises	Explicitly ask the seller not to start the engine before the call. If the engine is already warm, ask to see a cold start at a later time.
Keeping the camera moving fast	Leaks, damage, worn parts	Ask the operator to slow down and hold the camera steady on each area. Request close-up shots of specific components.
Covering leaks with dirt or grease	Hydraulic or oil leaks	Ask the seller to wash the machine before the call. If an area is suspiciously dirty, ask the operator to wipe it and show you the clean surface.
Pointing the camera away during operation	Smoke, unusual noises, component failure	Ask the operator to keep the camera on the exhaust and the machine during operational tests. Request a second person to film if the operator cannot both operate and film.
Replacing the hour meter	High actual hours	Cross-check the hour reading with the machine's age, wear condition, and service records. Look for signs of meter tampering (broken seals, mismatched screws). Use our verification guide.
Operating on flat ground only	Weak travel motors, steering problems	Ask the operator to drive on uneven ground or up a slope if possible. Ask for pivot turns to test both travel motors.
Showing a different machine	Bait-and-switch	Ask the operator to show the data plate and VIN on camera, and verify it matches the listing. Take screenshots of the data plate for comparison at delivery.

After the call: documentation and follow-up

When the call ends, your work is not done. Take these steps to document the inspection and follow up on any concerns:

1. Review the recording: Watch the recorded call again, taking notes on any issues you may have missed during the live call. Pause and zoom in on screenshots of specific components.
2. Write a condition report: Document the machine's condition in writing, including the hour reading, any visible issues, and the results of operational tests. Share this report with the seller and ask them to confirm or dispute your findings in writing.
3. Request still photos: Ask the seller to send high-resolution still photos of any areas that were not clear on the video, or of any issues you identified.
4. Follow up on red flags: If you identified a potential problem (smoke, leak, drift), ask the seller for an explanation and, if appropriate, a repair quote or a price adjustment. Do not ignore red flags — they will only become more expensive after delivery.
5. Arrange a third-party inspection (if needed): If the machine is high-value or if you have unresolved concerns, arrange an independent third-party inspection. ASURE offers inspection services that include a detailed written report with photos and measurements.
6. Save everything: Store the recording, screenshots, condition report, and all correspondence with the seller. These documents are your evidence if there is a dispute after delivery.

ASURE's remote inspection service

At ASURE Machinery, we offer a structured remote video inspection service for buyers who cannot visit our yard in person. Our process includes:

• A scheduled live video call with a dedicated sales representative and a qualified operator.
• A cold start (engine not started before the call) and full operational testing.
• A structured walkthrough covering all 29 inspection points from our 29-point inspection protocol.
• A written condition report sent after the call, with photos and the hour reading.
• Recording of the call provided to the buyer for their records.

We also encourage buyers to arrange their own independent inspection or to send a representative to our yard. Our goal is to make sure you know exactly what you are buying, whether you inspect in person or remotely. You can browse our current inventory — including the CAT 320D excavator, CAT 966H wheel loader, and SANY STC1000C6 truck crane — and schedule a remote inspection for any machine of interest.

FAQ

Can a remote video inspection replace an in-person inspection?

Not entirely. A live video call can reveal most visible and operational problems, but it cannot detect issues that require physical measurement (such as precise undercarriage wear percentages, internal engine compression, or hydraulic pressure readings). For high-value purchases, combine a remote inspection with an independent third-party inspection or an in-person visit. Use the remote inspection to filter out clearly problematic machines before investing in a more thorough inspection.

What if the seller refuses to do a live video inspection?

Treat it as a major red flag. A legitimate seller with nothing to hide will happily show you the machine on a live call. Refusal to do a video inspection, or insistence on sending only pre-recorded videos, is one of the 10 red flags in our buying guide. Walk away from sellers who will not cooperate with a live inspection.

How long should a remote inspection take?

A thorough remote inspection of an excavator or wheel loader takes 45–60 minutes, including the full walkaround, cold start, operational tests, and your questions. If the seller tries to rush the call or says "we only have 10 minutes," that is a red flag. Schedule enough time to inspect everything carefully — a rushed inspection is worse than no inspection because it gives you false confidence.

What should I do if I see smoke during the cold start?

Do not panic immediately — a small amount of white or gray smoke on a cold start can be normal, especially in cool weather. However, persistent smoke (lasting more than 30 seconds after startup), blue smoke (burning oil), or black smoke (over-fueling) under load are cause for concern. Ask the seller to explain the smoke and, if possible, to show you the engine after it has warmed up. If the smoke persists after warm-up, consider it a red flag and either negotiate a price reduction, require a repair before purchase, or walk away.

Should I record the call without the seller's permission?

Laws on recording video calls vary by jurisdiction, but in the context of a business transaction, it is generally best to ask for permission. Most legitimate sellers will agree to recording. If the seller refuses to allow recording, that itself is a red flag — you should take detailed notes and screenshots during the call instead. Never use a hidden recording as evidence in a dispute without consulting a legal professional.
