Operation
21. Getting steel frame or rebar between crusher jaws and cylinder rod clevis can
cause damage to the cylinder rod or crusher jaws. To avoid cylinder damage,
always remove demolition debris from the housing.
22. Do not operate excavator hydraulic cylinders when the crusher jaws are closed.
Bending the object up and down when the cutter-crusher jaws are pressed on it
may cause excessive wearing of cutter-crusher teeth and cutting blades.
23. The bearings must be well greased during operation. Regular inspections during
operation are recommended. If no grease is visible, bearings require more
frequent greasing. Bearings covered with excessive grease require less frequent
greasing.
