MTS Landmark Floor Standing - Manual (Page 53)

Caution:
Hydraulic fluid must be properly filtered.
Failure to maintain clean hydraulic fluid will lead to poor system performance and expensive
repairs.
MTS supplied HPUs incorporate the necessary filtration. If the source of hydraulic fluid pressure
is customer supplied, it is the customer's responsibility to ensure proper filtration.
Important:
The internal hydraulic connections from the actuator manifold and accessories (such as the hydraulic
lifts and locks) should already be made.
1. Connect the return line from the HPU to the hydraulic port on the manifold labeled “R”.
2. Connect the pressure line from the HPU to the hydraulic port on the manifold labeled “P”.
3. Connect the drain line(s) to the HPU.
a) Connect a drain line from the hydraulic port on the actuator end cap (labeled “D”) to the HPU.
b) If applicable, connect a drain line from the hydraulic lift/locks and hydraulic grip control to the HPU.
The lift/lock and grip supply drain lines are connected together inside the frame. A short drain hose is
supplied to be connected to a second drain line connected to the HPU.
4. Turn on the HPU and check for any hydraulic pressure leaks.
5. Turn on the actuator manifold (also called a hydraulic service manifold or HSM) and check for hydraulic
leaks in the load unit.
6. If you have hydraulic lifts, bleed the air out of the hydraulic lift cylinders.
Unlock the Crosshead
When the load unit is shipped, the crosshead is clamped to the columns with the manual clamping bolts in
the crosshead.
