03 · Service guidance

Operating limits

Preferred bulk fluid operating range35°C–50°C

Normal recommended working range for viscosity and water retention.

Continuous upper limit≤55°C

Maintain cooling and reservoir control below this value for routine service.

Maximum bulk temperature60°C

Do not intentionally exceed; test water content and viscosity if reached.

Short excursion limit65°C

Correct immediately; inspect for water loss and additive concentration.

Localized hot surfacesAvoid >80°C–90°C

Localized heating can accelerate water evaporation.

Invalid abuse condition>300°C cup heating

Outside hydraulic service; residue formation is expected and is not a normal-use rating.
