continue with soft foot measurement. Alternatively, you may wait for the process
to resume automatically.
Note
If the soft foot procedure is followed correctly, the above mentioned points will
not arise.
Parallel soft foot correction
In parallel soft foot, the machine rocks on two diagonal feet which are lower than
the other two. If two diagonal values are roughly equal and signicantly higher
than the other two, parallel soft foot can be assumed as a rst solution.
In Figure 7-14, the correction would be to place a 0.89 mm shim under foot ‘b’
(the foot with the largest gap).
Angular soft foot correction
In angular soft foot, the base of one or more feet is at an angle to the foundation
and is only partly in contact. If one value is signicantly higher than the others,
then angular soft foot can be suspected.
The ‘problem foot’ or machine frame is probably bent or distorted in some way. In
this case loosen the bolt and examine the foot more closely. Use a feeler gauge
to establish the variation of the gap and use these measurements to sketch the
shape and dimensions for a ‘stair stepped shim wedge’.
If the soft foot is purely ‘angular’ then the stepped shim will vary in thickness from
zero to twice the value displayed by the Product.
