TURNING AND CHANGING CUTTING BLADES
Warning! Prior to maintenance or inspection, operate all the control levers to
their fully extended stroke. This will release pressure within the hydraulic
piping and prevent unexpected movement of the jaw and loss of oil through the
hydraulic lines.
Warning! Support the jaw to prevent it from closing unexpectedly during
maintenance.
Used cutting blades can be recycled. Contact your dealer for more information
about local regulations of recycling.
■
We recommend rotating the blades every 100-200 hours of work to ensure
uniform wear of the cutting edges.
■
Once you have rotated or replaced the blades, it is necessary to control the play
between the cutting edges of the lower jaw and those of the upper jaw. This
distance must be between 0.3 mm (0.01 in) and 0.5 mm (0.02 in) in order to
prevent the material, especially if it is thin, from getting caught between the
blades.
■
If the blades are not rotated regularly (every 100-200 hours), uneven wear can
develop, which makes it impossible to shim the cutting edges correctly.
■
The blades should be rotated, on average, every 100-200 hours of work,
depending on the material being cut.
■
Remove and rotate the blades where possible, using one of the 4 cutting edges
(some blades cannot be rotated, others can be rotated up to 4 times).
1. Position the product on level ground.
2. Support the jaw.
3. Make sure the carrier's transmission is in neutral and the parking brake is
engaged.
