Three collars and limit switches control the travel
limits of the shearing and notching stations. This
photo shows the factory set positions for the three
collars.
Left Collar (A):
This collar controls the downward travel
limit of the shearing station's slide. This
collar should always be positioned fully
left, against its stop. Moving this collar
away from its stop prevents the shear from
descending completely and results in
incomplete cuts.
Middle Collar (B):
This collar controls the upward travel
limit of the shear only when the Shear /
Notch switch is in the "Notch" position.
This collar is usually set in the middle of
the collar bar. Moving this collar to the
right reduces the shear's upward travel.
Moving this collar to the left increases the
shear's upward travel.
Right Collar (C):
This collar controls the upward travel
limit of the shear only when the Shear /
Notch switch is in the "Shear" position.
This collar is typically positioned fully
right, against its stop, where it provides
full upward travel of the shear. As this
collar is moved to the right, the shearing
station's upward travel is reduced.
