The hydraulic filter located on the return side of the hydraulic tank comes

equipped with a restriction indicator gauge. This gauge shows the opera-

tor the condition of the filter element. When the needle reaches the red

band (25 psi), the filter is starting to bypass and the element needs to be

changed. Failure to change the element will result in premature wear and/

or failure of any or all of the hydraulic components. Only check gauge

with hydraulic fluid at operating temperatures. Cold oil is more dense

and will give a false indicator gauge reading.

If a cylinder seal leaks, disassemble the cylinder and ascertain the cause

of the leak. Small scores caused by chips or contaminated fluid can usu-

ally be worked out with fine emory cloth to avoid repetition of the trouble.

Whenever any seal replacement is necessary, it is always advisable to

replace all seals in that component. These seals are available in kits. Also,

thoroughly clean all components before reassembly.
