This is from the FSM - Can someone explain this to me???

7 Insert dial gauge and fasten so that contact button
rests on valve spring cap (arrow) with less than 3 mm
preloading (small dial gauge pointer).
Turn gauge dial until large pointer is on "0".

Caution:
Dial gauge contact button must be exactly perpendic-
ular to valve spring cap.

8 Continue to turn crankshaft in normal operating
direction until small dial gauge pointer has dropped
by 2 mm (valve lift) to 1 mm.

I clearly do not have much experience working with a dial indicator gauge!
