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

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.
