Fig. 37 Adjusting the brake lever
Make particularly sure that the stop link snaps into the groove of the stop
cam freely. The tension springs must be strong enough to pull the stop
motion
and brake lever assembly securely against the stop cam when the
machine stops. The stop link should be allowed only a small omount of
play in the stop cam groove. If the edges of the stop link or the stop cam
are worn, these ports must be replaced instantly.
(2) Tripping Lever
Adjust the height of the tripping dog at the front end of the tripping lever
so that the stop tripping segment on the rim of the feed cam will depress
it far enough to ensure secure stopping of the machine.
