6. Safety & Warranty

Q1: What safety precautions should be followed when working with the A10VSO pump?

• Lockout/Tagout (LOTO): Before disassembling the pump, turn off the motor and relieve system pressure (open the relief valve) to avoid accidental startup or oil spray.
• Pressure testing: Never exceed the pump’s peak pressure (350 bar) during testing; use a pressure gauge with a range ≥ 400 bar to monitor pressure.
• Protective gear: Wear safety glasses, gloves, and oil-resistant boots when handling hydraulic oil (prevents skin irritation and eye injury).
• No modifications: Do not modify the pump’s housing, swashplate, or control mechanism (voids the warranty and may cause catastrophic failure).
