Do you lube torque wrenches?

[scottproonly]

Hi all. My X-tools torque wrench has a small hole in it capped off with a rubber plug. Its not mentioned in the instructions.
Is this to lube the innards?
If so what oil and amount do you use?
Thanks

Re:

I would say that it is likely to be an access hole that can be used to calibrate the tool.

It would recommend leaving well alone - there are companies who can calibrate these tools, but it will cost a bit.
