Cleaning Operation
The purpose of cleaning the hydraulic oil is to remove
contaminants of all types and sludge.
Procedure
1 Retract all rams.
2 Drain the hydraulic tank.
3 Remove and flush the tank ensuring that it is clean and
dry.
4 Fit a new 5 micron rated filter element, part number
581/18020.
5 Refit the tank and fill with new oil of the recommended
grade. Note that a close check needs to be kept on the
tank level as the hydraulic system is being filled (not just
the tank).
6 Disconnect and remove the pump to motor loop hoses.
Using compressed air, blow down the loop hoses to
remove oil and debris particles. Refit the hoses.
7 Disconnect the hydraulic lines to the rams.

WARNING
Make sure all services are safely supported before
disconnecting hydraulic lines.

8 Slowly activate each circuit to flush the lines with new
oil.
! !
WARNING
The oil will be under pressure. Make sure the hose ends
are secured and emptying into a suitable container.

Check oil level and top as required.
9 Connect the hydraulic line to the head side of the rams
(the retracting side), leave the rod side disconnected.
10 At low engine revs, operate the services slowly to
extend the rams, this will expel the dirty oil from the rod
side of the rams and new oil will be put into the head
side. Check oil level and top as required.
11 Reconnect the rod side lines. Check oil level and top as
required.
12 Operate all rams for approximately 15 - 20 minutes
whilst building engine speed up to full throttle.
13 Replace the hydraulic filter, again using a 5 micron
element, part number 581/18020.
14 After 250 hours operation or at the first 250 hour service
(whichever occurs first) the hydraulic filter should be
replaced with the standard element.
