the motor has been turned off. Make sure
that the crusher has stopped completely
before opening any covers, performing any
maintenance, or adjusting the crusher.
2. Before performing any maintenance or
repair work, make sure that the crusher is
stopped and locked out.
3. The surfaces of the crusher may become hot
during crushing. Hot surfaces can cause
severe burn injuries. Make sure that the
surfaces have cooled before performing any
maintenance work.
4. Before changing any wear parts of the
crusher, read chapter 6: Replacement of
wear parts and appendixes A and B
carefully.
5. Before lifting any wear parts, check the
weight of the component and ensure that
lifting equipment being used is adequate to
lift the weight. In addition, familiarize
yourself with all the special tools provided
with the crusher specifically for replacing
the wear parts.
6. Read the instructions regarding the lifting
tools and replacing wear parts carefully
before replacing any wear parts. Make sure
that the parts are adequately supported
before lifting. Never go under the suspended

crusher are designed to be used only with
original Metso wear parts.

adjustment may accumulate significant
amount of energy. Follow the instructions
strictly and be extremely accurate when
adjusting the spring. Never release the
