🔌 Function

Stores and delivers hydraulic pressure to crank the engine on a hydraulic starting system.

⚠️ Common Signs of Failure

• Engine cranking slowly or not at all
• Stored pressure bleeding away between starts
• Hydraulic oil weeping from the unit or its hoses
• Pressure not building while the charging pump runs
• Groaning or knocking from the unit as it charges

🛠️ Service Notes

• Discharge the stored pressure before disconnecting anything — the unit holds energy with the engine stopped
• At 47 kg this is a lifting-gear item and may need freight rather than standard parcel carriage
• Check charge pressure and the hoses before condemning the unit
