I have one forklift (Cat TC60C).

The forklift drives and works in general. However, at idle speed, the
hydraulics does not work at all -- I have to step on gas to, say, lift
the forks or tilt.

I do not really understand how that could be the case, any ideas?

I wonder if it has a hydraulic pump keyed to engine rpm, or a pump
which is leaking so badly at low rpms, it can't perform. Ask CAT if
you don't have a manual for it which states something like that.
