FAQ
-
01
What should I confirm before buying a used machine?
Confirm the exact model and identification details, available photos or videos, included attachments and the condition information available for that machine. Good cosmetic appearance or a low displayed hour reading alone does not establish mechanical condition. Agree any further checks and the written equipment description before payment.
-
02
Can I request photos, videos or an inspection?
Contact HCQ with the listing or model you are considering and ask which current photos, operating videos or inspection information are available. If you want an additional inspection, discuss its scope and arrangements before ordering. Do not assume that every machine listing includes an independent inspection report.
-
03
How is the delivery schedule confirmed?
Delivery timing depends on machine availability, agreed preparation, payment confirmation, loading arrangements and the shipping route. Ask HCQ for an order-specific schedule. Dispatch from China and arrival at the destination are different dates; confirm both where applicable.
-
