Routine maintenance

1. ROUTINE MAINTENANCE

1.1 OVERVIEW

This product is a precision made hydraulic machine. Therefore great care and
cleanliness should be taken when handling any of the hydraulic components. Dirt is
the worst enemy in hydraulic systems.
Handle the parts carefully and remember to cover any cleaned and dried parts with
clean lint-free cloth. Do not use anything other than purpose designed materials for
cleaning hydraulic parts. Never use water, paint thinners or carbon tetrachloride.
Components, gaskets and seals in the hydraulic system should be oiled with clean
hydraulic oil before assembly.
Remember to grease the crusher parts regularly according to the instructions in this
manual. See "Greasing" on page 42.
Close the crusher jaws during maintenance or inspection. If you must leave the jaws
open, remember to block the jaws to prevent them from closing.
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.
