About the Knowledge Centre

Who writes these guides?

Our own sales engineers, from the questions buyers actually send us before an order.

Do the guides cover machines you do not sell?

Where it matters, yes. A buying guide is useless if it pretends only one type of machine exists.

Can I ask a question that is not covered?

Send it on WhatsApp. If the answer is useful to other buyers it usually becomes the next guide.

Are the figures in the guides model specific?

No. Guides explain the principle; model specific numbers live on the product pages and in the quotation.

Can I reuse this material?

Link to it freely. Ask first before republishing the text.

Question Not Answered Here

Ask it directly. Our engineers answer selection questions without putting you into a sales sequence.
