The following examples explain how to use
the thread dial and the thread dial chart.
TPI Ending in

,
use only the number 1 on the thread dial (see the
example in
Figure 85).
TPI Divisible by 2: For threading a TPI divisible
by two, use any numbered line on the thread dial
(see the example in
Figure 87).

Important: Once a number has been selected,
continue using that number or its opposite on the
dial.
For example:
• If you make the first threading pass and select
1, then all following passes you must select
the 1 or its opposite, number 5.
• If you make the first threading pass and select
3, then all following passes you must select
either the 3 or its opposite, number 7.

TPI Divisible by 4: For threading a TPI divisible
by four, use any line on the thread dial (see the
example in
Figure 88).
TPI Divisible by 8: For threading a TPI divisible
by eight, any position on the thread dial may be
used, even in-between the marks (see
