Cleaning Operation
The purpose of cleaning the hydraulic oil is to remove
contaminants of all types and sludge.
Procedure
1 Retract both rams.
2 Drain the hydraulic tank.
3 Remove and flush the tank ensuring that it is clean
and dry.
4 Fit a new filter element.
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.

8 Slowly activate each circuit to flush the lines with new
oil.
!MWARNING

ends are secured and emptying into a suitable
container.
0079
Check oil level and top up 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 up as required.
11 Reconnect the rod side lines. Check oil level and top
up as required.
12 Operate both rams for approximately 15 - 20 minutes
whilst building engine speed up to full throttle.
13 Replace the hydraulic filter.
14 After 250 hours operation or at the first 250 hour
service (whichever occurs first) the hydraulic filter
should be replaced.
