Adjusting the Clamping Mehanism of Index Drum F.
After constant use the the clamping lever T6 may no longer function correctly to lock the the swivel
index drum F. To correct this screw U2 will need to be asdjusted. To do this remove the swivel arm
as described above. Remove screw U3 and stop plate A1. Back off nut M2 and screw U1 and
pull out the clamping lever T6. Lift off the index drum F to access the adjusting nut and screw U2.
Rotate the screw 180° relative to the nut to reduce the length. Then reassemble.
Adjusting the stop pin for the 90° Swivel Motion
Constant striking of the stop plate Al against stop pin A2 and A3, could cause the angle to no
longer be exactly 90°. Correct the adjustment by turning the two eccentric stop pin A2 and A3 until
the angle is correct. Turning the stop pin A2 will change the cylindrical setting of the collet sleeve
bearing, while turning stop pin A3 will adjust the 90° swivel motion.
