1.
Clean points.
2.
Loosen screws A and align contact points so that full contact area is used.
3. Loosen locknut C and adjust screw B for correct air gap. There are 40
threads per inch on contact screw, giving
.025"
movement for each turn. Air gap of
CB's 1,
2, 3
and 4 is
.025
".
On all others the air gap may vary from .012
"
to .040
"
t o obtain the correct contact duration.
4.
Form a t E so that contact surfaces meet squarely.
5. Loosen screws D and turn cam to obtain proper timing as given on electrical
timing chart supplied with each machine.
