4. Stop the carrier engine.
5. Clean the cutting blades and the base.
6. Lower the upper jaw until just before the front blade engage the corresponding
blade of the fixed lower jaw. Measure the distance with a gauge.
7. Continue lowering the moving shank until the entire front blade has engaged the
corresponding fixed blade. Measure the clearance between the blades with a
thickness gauge in the rearmost part of the blade.
8. Continue to lower the shank, repeating the procedure for the rear blades.
9. If the measured clearance exceeds the recommended value of 0.3 mm (0.01
in)...0.5 mm (0.02 in), insert an appropriate number of shims behind the blades
to restore the correct clearance between the blades.
NOTICE! It is recommended to keep the less worn blades in the upper jaw and
to shim only in the lower jaw. Do not exceed 3.5 mm (0.14 in) thickness;
instead, replace the worn blade.
■
To add thickness, open the shear completely, loosen the screws holding the
blades, and insert the shims between the blade and its housing.
WARNING! Use external constraints to prevent the mobile body from closing
accidentally.
■
Tighten the screws to the specified torque.
■
Close the shear slowly and recheck that the clearance is correct.
10. After any rotate of the blades, always use a gauge to check that the relative
clearance between the primary and secondary blade of the moving body and the
respective blades of the fixed body does not exceed 0,5 mm (0.02 in).
