Remote assistance
Our technical team
A video call with a technician who opens your machine's parts diagram while you talk.
- Alarm and parameter review
- Installation and wiring checks
- No limit on questions
LeanSupportIncluded with every machine, at no extra cost
Buy direct from the factory without being left alone when the machine stops.
Distance from the manufacturer is the real reason almost nobody buys direct, whether that factory is in Italy or in China. LeanSupport is the structure we put in between: one point of contact in Spain, three routes of intervention, and your machine's history kept from day one.
Which machines it covers
LeanSupport covers only machines supplied through LeanZupply. We don't provide technical service for equipment acquired elsewhere, because our work rests on the history, the parts diagram and the factory channel of every machine we've supplied.
You open the case with us
Not with the manufacturer, not in another language, not in another time zone.
Remote diagnosis first
Before anyone travels, a technician looks at the machine with you.
Technicians in every province
For what needs a physical presence, there's a network across the country.
History and parts diagram kept
When you ask for a part, we know exactly which one it is.
How we work
One point of contact, whether the part is 500, 3,000 or 10,000 km away.
When something fails, the conversation starts and ends with us. We open the case, diagnose it, talk to the factory if needed, and coordinate the intervention or the shipment of the part.
The procedure is the same for an Italian manufacturer and for a Chinese one: the timeline changes, the process doesn't. You never negotiate with the manufacturer.
Three routes of intervention
We start with the fastest route and only escalate if we have to.
Most stoppages aren't breakdowns: they're settings, installation or use.

Technician in your province
Integrated technician network
When remote diagnosis isn't enough, we coordinate an on-site visit.
- Coverage across the country
- Visit coordinated by us
- Report goes into the history

Escalation to the factory
Direct after-sales channel
If the part or the decision belongs to the manufacturer, we handle it on your behalf.
- Open channel with every manufacturer
- Part identified by reference
- Case handled in your language

Warranty
What it covers and what it doesn't.
Covered
- Manufacturing defects for 12 months
- Replacement of defective components after technical diagnosis
- Full handling of the case with the factory, on your behalf
- Remote assistance with no limit on questions
Not covered
- Impact and transport damage not declared on receipt
- Incorrect installation or installation by unqualified personnel
- Improper use or use other than per the manual
- Incorrect supply voltage or poor electrical installation
- Natural wear of consumable parts
After the warranty, we're still here.
Past 12 months, remote assistance and parts handling continue unchanged. The part and the intervention are quoted separately.
Specific conditions may vary by manufacturer. Those for your machine are stated on its record.
Frequently asked questions
The questions people actually ask us.
Do you service machines I didn't buy from you?
No. LeanSupport rests on the history, the parts diagram and the factory channel of every machine we've supplied. Without those, what we could offer would be a phone number, not a service.
Is the warranty from the factory or from LeanZupply?
The warranty is the manufacturer's, but you open the claim with us and we handle it on your behalf. You never negotiate with the factory.
How long do you take to fix a breakdown?
We don't give a figure we can't meet. What we do guarantee is the order: remote diagnosis first, on-site intervention or a part next, and escalation to the factory if needed. Each step is dated in your account.
Do you keep spare parts in stock?
We don't hold spare-part stock. What we hold is your machine's parts diagram and the channel to its manufacturer, so we identify the part by reference and handle the shipment without you having to describe it over the phone.
Is the technician who visits from LeanZupply?
We work with a network of integrated technicians by province. We coordinate the visit, and the report goes into your machine's history.
What if the machine is from a European manufacturer?
The procedure is identical. With a European factory a part usually arrives sooner, but the process — who opens the case, who diagnoses, who talks to the factory — doesn't change.
What happens after the 12 months are up?
Remote assistance and parts handling continue unchanged. What changes is that the part and the intervention are quoted separately.
