The W2900 series comes standard with a Lug-On-Center back. The
back is easily removed by unscrewing the four back screws as shown
in Fig.19.
Do not touch any of the inner workings of the indicator, and protect
them from liquids, dust, and any other for-eign matter. Replace the
back-lug as soon as possible. Some examples of the different backs
are listed below.
The Contact Point is another one of the parts on your indicator that
is interchangeable. The contact point can be removed by carefully
while holding the spindle firmly with one hand and then unscrewing
it counter- clockwise with your other hand. Replace the contact point
the same way, turning the tip on clockwise. Remember to tighten the
tip finger tight. Excessive radial rotation of the spindle shaft may cause
your indicator to stop func-tioning properly. Special contact points are
listed on the next
page.
