1. Fit the dial gauge and arm to the dial gauge stand.
2. Centralise the dial gauge on the adapter and set to
the required preload.
Caution:
The measurement should be done gently. Applying
too much force will result in inaccurate measure-
ments and could damage the DMF.
3. Gently push the slotted arm towards the engine (using
your thumb, for example) until resistance can be felt.
Keep the slotted arm in this position while setting
the dial gauge to “0”.
