Frequently asked questions
What safety precautions are required when servicing the pump?
Operators must prevent machine slip, avoid using flammable cleaning agents, and handle pressurised oil with protective eyewear to avoid injury.
What control options are available for the pump?
The pump can be equipped with Pressure Compensation (PC) control or Load‑Sensitive (LS) control, the latter optionally combined with PC.
How are the control valve bolts tightened during re‑assembly?
Four control‑valve bolts (C300) are tightened to a torque of 5.4 – 7.5 N·m in a diagonal sequence, then re‑checked.
What torque values are required for the pump’s fasteners?
Typical torque values range from 10.8 – 13.5 N·m for 3/16‑inch bolts and 5.4 – 7.5 N·m for 4‑mm bolts, as listed in the torque table.
