Recommended Annual Inspection

It is recommended the following components and features of the ECAT to be evaluated at least
once a year.

•

Check hydraulic fluid levels

•

Check the pressure gauges

•

Check bolts and fittings for tightness

•

Check for external oil leaks

•

Check the pneumatic fittings with a leak detection product such as Snoop liquid leak

detector from Swagelok or comparable.

•

Check handpump operation functions properly

•

If/When possible, perform a function test (See Section 4.6 for instructions on how to
perform a function test)

•

Check accumulator and thermal volume controller function

•

Check the breather on the hydraulic reservoir

•

Check the return filter, if included
