Is it ok to add hydrolic oil to the front suspension of my honda xl125l?

The technician added hydrolic oil in the front suspension of my Honda xl125l. Since then am nolonger feeling comfortable raiding. What should I do or what should he ought to have done.

In the internet age I may sound crazy but TALK TO HIM,.Yes, ask is it right oil? Right amount? Did he do anthing else? Like tire pressure.
